Safer Power Options on the Horizon for Medical Implants and Wearables

Biocompatible Supercapacitors to Transform Next-Gen Power Sources

 

Discover the future of implantable devices with biocompatible supercapacitors!—Listen now!

 

If you have ever had to replace a battery in a device, you know it can be a hassle. For many, this hassle becomes even more serious when that device is inside the body. Pacemakers, cochlear implants, and sensors are some of the medical devices that millions have come to rely on and these devices are powered by batteries that can be harmful and even require frequent replacement. A team of researchers at Khalifa University has comprehensively reviewed this challenge and found materials like activated carbon, graphene, and some of metal oxides, to make devices powered by energy storage systems, such as ‘biocompatible supercapacitors’(B-SCs), safer and more efficient.

 

H.E. Prof. Ebrahim Al Hajri, Professor of Practice, Mechanical and Nuclear Engineering, Dr. Amal Al Ghaferi, Associate Professor, and Research Scientists Dr. Nilesh R. Chodankar, Dr. Jang-Kyo Kim from Department of Mechanical and Nuclear Engineering, and Dr. Rohan B. Ambade, Aerospace Engineering, Khalifa University, published a review in a paper titled ‘Revolutionizing Implantable Technology: Biocompatible Supercapacitors as the Future of Power Sources’ in Advanced Functional Materials, a top 10% journal, in the field of Condensed Matter Physics. The team also includes Prof. Yun-Suk Huh, Inha University, South Korea; Prof. Young-Kyu Han, Dongguk University-Seoul, South Korea; and Dr. Pragati A. Shinde, National Institute for Materials Science, Japan.

 

Traditional lithium-ion batteries have long been the standard power source for not only implantable electronic medical devices — such as sensors, pacemakers, implantable cardioverter defibrillators, cochlear implants, and stimulators — but also in various wearables applications. When embedded in the body, electronic medical devices can help in treatments and diagnosis, and while they may be small, such devices contain various electronic components, such as integrated circuits, sensors, and power sources like batteries and biofuel cells, which can pose risks due to potential leakage of toxins. Another common drawback is the frequent battery or device replacements that can require surgery, increasing risks for patients and raising healthcare costs.

 

Dr. Nilesh

“Biocompatible supercapacitors can improve medical implants and wearables with safer long-lasting energy sources, reducing risks and improving patients’ quality of life.”

— Dr. Nilesh R. Chodankar, Research Scientist, Mechanical & Nuclear Engineering, Khalifa University.

Materials used in biocompatible supercapacitors, such as activated carbon and graphene improve the performance of supercapacitors and being ‘biocompatible’, they can safely interact with biological tissues. Additionally, supercapacitors have advantages even over rechargeable batteries, including high power, long lifespan, low internal resistance, affordability, non-toxicity, and low maintenance. When integrated with energy harvesting and conversion systems, supercapacitors that supply power for biomedical devices can deliver reliable energy over long periods to implantable devices which can be placed inside the body or worn on the skin.

 

Dr Nilesh R. Chodankar, said: “Recent studies have focused on the best electrode and electrolyte materials for wearable and portable devices. However, there is currently no review on biocompatible supercapacitors (B-SCs) for Implantable Electronic Medical Devices. It is essential to fill this gap to tackle existing challenges and this review will cover advancements in B-SC materials, design strategies, power requirements of various IEMD technologies, and the critical features needed for their energy storage systems.”

Khalifa University Researchers Validate Potential Discoveries of Ancient Civilization at Saruq Al Hadid and Al Ain Archaeological Sites

Satellite Imagery, Ground Penetrating Radar Reveals Buried Structure, Aflaj Systems, Umm an-Nar tombs, and Ancient Buildings

 

Khalifa University of Science and Technology today announced researchers from the Environmental and Geophysical Sciences (ENGEOS) lab and the Earth Science department have detected the presence of a long, buried remains, which may resemble a wall or an ancient building, at the Saruq Al Hadid archeology site in Dubai, and signs of historic settlements in Al Ain, through advanced ground penetrating radar, demonstrating that their method can be used to spot potential archaeological sites buried under the sand, from space.

 

The method was developed during this first phase of the project led by Khalifa University’s Dr. Diana Francis, Head, ENGEOS lab, and Assistant Professor, Earth Sciences, applying machine learning algorithms to high-resolution satellite imagery, and advanced image processing techniques to detect and map buried archaeological features at the site. An archaeological excavation is still required to confirm the discoveries at Saruq Al Hadid, while collaboration with Dubai Culture has already been initiated to proceed with manual investigations at the site by archaeological missions.

 

The researchers have already applied their innovative method to investigate sites of archeological importance in Al Ain in collaboration with the Department of Culture and Tourism – Abu Dhabi, with this ongoing work leading to the discovery of several ancient water channels (Aflaj) and related irrigation systems, buried tombs of the Bronze Age Umm an-Nar culture, and other ancient buildings. The researchers are planning to apply this method to other areas in the UAE, including Umm Al Quwain.

 

His Excellency Professor Ebrahim Al Hajri, President, Khalifa University, said: “The validation of results at the archaeological sites in Abu Dhabi and Dubai strongly reflects Khalifa University’s emphasis on locally and globally-relevant research projects that positively impact the community. By developing an effective method to support exploration of areas for information on ancient civilization, our researchers have once again demonstrated their commitment to obtain suitable solutions through scientific innovation. We believe our achievement will immensely benefit local and global stakeholders, especially those involved in archaeology.”

 

Muna Faisal Al Gurg, CEO, Culture and Heritage Sector, Dubai Culture, highlighted the site’s rich archaeological value and its role in emphasizing the historical significance of Dubai and the region, saying: “Saruq Al Hadid is one of the most important and largest archaeological sites in the southeastern part of the Arabian Peninsula dating back to the Iron Age, and the discovery of significant findings during previous excavations has enhanced the site’s status and its scientific importance.” She commended the efforts of the team at Khalifa University of Science and Technology during the period of study which has resulted in the confirmation of the presence of buried structures at Saruq Al Hadid, representing a qualitative leap in the excavation processes witnessed by the site. “The results of the study will pave the way for more archaeological discoveries within the site, which will enrich scientific research related to the archaeology sector in Dubai and the UAE, and increase knowledge about the economic activity and lifestyles experienced by the area’s inhabiting civilizations during the Iron Age.”

 

Dr. Diana Francis

“The ENGEOS Lab’s pioneering research at Saruq Al Hadid and Al Ain archaeological sites sets a benchmark for the development of remote sensing archaeology capabilities and automates and refines the process, so we can improve accuracy and minimize potential errors.”

This pioneering research not only sets a benchmark for the development of remote sensing archaeology capabilities at a national and regional level but by automating and refining the process, we can improve accuracy and minimize potential errors before expanding the methodology to larger areas.” 

 

One of the aims of the method, which used advanced satellite images, machine learning and radar sensors, was to be able to pinpoint specific regions within a vast area from which archaeologists may start their search, saving extensive time and resources for archaeologists by enabling targeted investigations based on satellite and machine learning predictions. Moreover, this groundbreaking approach conducted by the ENGEOS Lab holds other far-reaching implications, particularly in addressing the challenges of remote sensing in desert environments like the UAE, where classic satellite imagery can be compromised by the fact that archaeological sites get buried under the sand with time.

 

Looking ahead, the ENGEOS Lab has outlined two main objectives as they aim to apply and refine their method in similar desert environments to enhance the algorithm’s efficiency and provide additional evidence of its effectiveness. The team also intends to apply their approach to known sites, comparing geophysical data with the findings of professional archaeologists to further enhance the learning capabilities of the intelligent systems model.

New approach paves the way for more resilient and efficient microgrid operations, contributing to a more sustainable and stable energy future

 

Unlock the future of renewable energy storage—listen now!

‌

 

As the world shifts towards using renewable energy sources (RESs), managing their inherent intermittency becomes crucial. This is particularly evident in hybrid microgrids that combine wind and solar power. A team of researchers from Khalifa University has developed a sophisticated control strategy that promises to enhance the stability and efficiency of these systems.

 

Dr. Muhammad Bakr Abdelghany, Prof. Ahmed Al-Durra and Prof. Hatem Zeineldin, with Prof. Fei Gao, University of Technology of Belfort-Montbéliard, France, created a novel approach that integrates hydrogen energy storage with advanced model predictive control. They published their results in IEEE Transactions on Industrial Informatics, a top 1% journal.

 

Hydrogen energy storage systems are central to this new strategy. Unlike traditional batteries, hydrogen storage offers high density and is suitable for long-duration storage, making it an ideal solution for balancing the fluctuating output of RESs. In this hybrid microgrid setup, hydrogen is produced when surplus energy is consumed when there is a deficit, ensuring a steady power supply.

 

The innovation lies in a dual-layer control architecture. One layer handles long-term operations, scheduling hydrogen production and consumption to meet daily energy demands. It also participates in the daily electricity market to maximize revenue and minimize operational costs. The other is focused on short-term operations, correcting deviations between forecasted and actual conditions in real-time. This layer optimizes power production and ensures smooth energy delivery to the grid based on a sophisticated control approach.

 

By coordinating these two layers, the system effectively balances long-term planning with real-time adjustments, addressing both economic and operational challenges.

 

To validate their approach, the research team conducted extensive numerical simulations and laboratory tests at the Energy Systems and Control Optimization (ESCO) Lab, Khalifa University. They demonstrated that their system effectively manages the hybrid microgrid, meeting energy demands while optimizing economic performance. They also saw a significant reduction in power fluctuations and fewer state switches for hydrogen devices compared to traditional control methods.

 

This innovative control strategy represents a significant step forward in managing hybrid microgrids. By integrating hydrogen energy storage with advanced predictive control, the system enhances the stability and efficiency of RESs. As the world transitions towards sustainable energy, such advancements are crucial for ensuring reliable and economically viable power systems.

Can This New Material Supercharge the Future?

Iron-Based Metal Organic Framework Shows Stability for Energy Storage  

 

Explore breakthroughs in supercapacitor technology with Fe-Tp MOFs—listen now!

 

Smartphones and electric cars both need energy sources that charge quickly and last long—the kind of power supercapacitors deliver, unlike traditional batteries. But the use of acids in such devices can hinder the advancement of energy storage materials development, a limitation that researchers at Khalifa University have addressed by developing a new iron-based conjugated metal–organic framework (Fe-Tp MOF). The research findings have been protected by a US patent application. 

 

The research was published in a paper titled ‘Iron salicylaldehydate conjugated metal–organic framework for quasi solid-state supercapacitor’ in the Chemical Engineering Journal, a top 1% journal.  

 

The research effort was led by Dr. Dinesh Shetty, Associate Professor of Chemistry and a Theme leader in the Center for Catalysis and Separations (CeCaS), Khalifa University, and the team includes Safa Abdullah Gaber, a PhD student; Dr. Abdul Khayum Mohammed, a Postdoctoral Fellow, and Gigi Xavier. Other authors are Yao He, New York University – Abu Dhabi, Ajmal Pandikassala, and Maria Kurian, CSIR-National Chemical Laboratory, Pune, India, Pilar Pena S´anchez, and Dr. Felipe Gandara, Instituto de Ciencia de Materiales de Madrid-CSIC, Madrid, Spain, and Dr. Stefano Canossa, Max Planck Institute for Solid State Research, Stuttgart, Germany.  

 

A material like Fe-Tp is more compatible with several highly acidic electrolytes that conduct electricity between the electrodes in traditional supercapacitors, leading to better performance and longer life for the supercapacitor. Beyond acid resistance, Fe-Tp can also withstand high humidity levels and air pollutants. This material is durable and can be charged and discharged 36,000 times without losing much of its ability to store energy, retaining 80% of its initial capacity. It can also tolerate extreme temperatures – keeping 93% of its mass up to 280°C – while being stable in a variety of solvents, including boiling water.  

 

Dinesh-Shetty

“Our research team developed a stable material for supercapacitors, offering long-lasting performance and opening the door to more durable and efficient energy storage solutions.”

— Dr. Dinesh Shetty, Associate Professor of Chemistry and a Theme leader in CeCas, KU.

Fe-Tp also exhibits a strong capacity for capturing CO2, making it useful for carbon storage and separation. In addition, with its ability to absorb visible light and a calculated band gap, Fe-Tp could find its way into electronic devices. Additionally, the researchers employed a simple, solvent-free mechano-mixing reaction to synthesize Fe-Tp to eliminate the need for large volumes of solvents, making the production process potentially more cost-effective and environmentally friendly, which is a paradigm shift in the conjugated MOFs research field. The efforts on scalability which can be difficult to achieve for conjugated MOFs are currently underway in Dr. Shetty’s research group.  

 

Dr. Dinesh Shetty said: “The primary aim of this research was to develop a conjugated metal-organic framework (MOF) that addresses the persistent challenge of chemical instability in existing supercapacitor materials. Our findings highlight the potential of Fe-Tp as a reliable electrode material, ensuring long-term performance in supercapacitors, opening doors to more durable energy storage systems. The strong coordination bond between two oxygen atoms from the Tp and strong Lewis acid Fe3+ contributes to the material’s remarkable stability, further enhancing its practicality for large-scale production.”  

 

Dr. Shetty has six patents to his name and is the author of 53 peer-reviewed journal papers and more than 30 conference papers.

Clothes equipped with sensors and next-generation wearables could soon transform our wardrobes and gadgets into health-tracking devices. As this technology evolves, researchers at Khalifa University have developed all 2D materials-based humidity sensor that adapts to our movements—working perfectly even when bent or stretched.  

 

Using innovative 2D materials like Ti3C2Tx MXene nanosheets and Graphene Oxide, the humidity sensing device improves wearable tech in health monitors and creates a more responsive environment in smart homes. The research was published in a paper titled ‘2D Ti3C2Tx-MXene nanosheets and graphene oxide based highly sensitive humidity sensor for wearable and flexible electronics’ in the Chemical Engineering Journal, a Top 1% journal Scopus 2023.

With Ti3C2Tx MXene nanosheets as flexible and highly conductive electrodes and Graphene Oxide as the sensing layer, the humidity sensing device offers practical solutions for everyday use replacing traditional humidity sensors relying on the use of metallic electrodes with MXenes—thin layers of transition metal carbides—offering better conductivity and mechanical durability.  

 

The sensor operates on the principle that certain materials change their electrical properties when exposed to humidity. In this case, the MXene nanosheets serve as electrodes while the graphene oxide acts as the sensing layer. When humidity levels change, the sensor can detect these variations, responding to moisture levels from as low as 6% to as high as 97% at frequencies of 1 kHz and 10 kHz, maintaining stable performance over 24 hours. 

 

 

The potential uses for this technology are vast. Beyond just measuring humidity, the 2D materials-based humidity sensor can detect nearby objects or people without physical contact, making it useful for smart devices. Another standout feature is the sensor’s quick response time, taking only about 0.8 seconds to register changes in humidity – a crucial requirement for real-time monitoring of breathing patterns, creating responsive environments in smart homes, or advancing the agriculture sector. 

 

Dr. Shoaib Anwer said: “The practical applications of these nanomaterials are essential for addressing energy and environmental sustainability concerns as there is an urgent need to replace conventional, complex synthesis methods with low-cost and straightforward processes. The mechanical durability of 2D MXenes allows sensors to withstand stress, making them ideal for flexible and wearable sensing devices. This research not only showcases the potential of 2D MXenes as conductive and flexible electrodes but further explores the application of 2D materials in wearable electronics.”

Revolutionizing Fuel Cell Catalysts for a Clean Energy Future

Fluorine-doped carbon catalysts break barriers in fuel cell technology for a greener future

 

Revolutionize clean energy—listen now!

Hydrogen-based fuel cells have emerged as a leading contender to replace traditional internal combustion engines as the world moves towards cleaner, more efficient energy technologies. However, the widespread adoption of fuel cells has been hindered by the high costs and limited availability of platinum, the standard catalyst used for the crucial oxygen reduction reaction (ORR).

 

A team of researchers, including Khalifa University’s Prof. Akram Alfantazi and Dr. Karuppasamy Karuppasamy, has investigated using fluorine-doped carbons as a breakthrough innovation to revolutionize fuel cell technology. With researchers from Keimyung University, South Korea, Central Electrochemical Research Institute, India, Academy of Scientific and Jiangxi University of Science and Technology, China, the KU team reviewed the potential of fluorine-doped carbons in making fuel cells more stable and durable.

 

Their review was published in Coordination Chemistry Reviews, a top 1% journal.

 

Fuel cells generate electricity through electrochemical reactions, with the ORR at the cathode a key step. Historically, platinum supported on carbon has been preferred due to its high activity, but platinum’s high cost and susceptibility to fuel impurities limit its commercial viability.

 

Fluorine-doped carbons may represent a significant advancement. The electronic properties of carbon are modified through the introduction of fluorine, the most electronegative element in the periodic table. This doping changes the electronic band structure of carbon, enhancing its interaction with oxygen molecules and improving the ORR activity.

 

The fluorine also enhances durability, which is particularly crucial in the harsh conditions within fuel cells where stability against corrosion and oxidative potentials is paramount. Fluorine-doped carbons are exceptionally resistant to carbon corrosion, even in highly acidic and alkaline environments. This resilience is attributed to the formation of highly polarized carbon-fluorine bonds, which not only fortify the carbon matrix but also prevent degradation during the start-up and shut-down cycles of fuel cells, which are typically challenging for conventional catalysts.

 

More resistance to degradation means longer catalyst life and more reliable performance. Plus, fluorine-doped carbons can also work synergistically with other atoms like nitrogen, sulfur, boron and phosphorus. This could create more active sites for catalysis and introduce further beneficial defects in the carbon lattice, boosting the ORR activity. Nitrogen and fluorine co-doping, for example, has shown exceptional results, dramatically lowering the energy barriers for ORR and enhancing the overall efficiency of the fuel cell.

 

“The potential applications of fluorine-doped carbons extend beyond fuel cells,” Prof. Alfantazi says. “Their enhanced catalytic properties make them suitable for various electrochemical devices, including batteries and supercapacitors. Ongoing research aims to optimize the synthesis methods for these materials, focusing on achieving the perfect balance of dopants and structural properties to maximize performance and durability.”

 

By overcoming the limitations of traditional platinum-based catalysts, fluorine-doped carbons pave the way for more efficient, cost-effective and durable fuel cells.

Two Khalifa University PhD researchers from the Earth Sciences department have become the first from the UAE to attend the paleoclimatology summer school held annually in Urbino, Italy. The 20th edition of the Urbino Summer School in Paleoclimatology (USSP) consortium focuses on understanding the methods and models used to examine climate change through Earth History.  

 

The two PhD researchers, Marwa Mohamed Shahid Vadakke Painkal and Indodeep Apurba Ghoshal, also presented their research, supervised by Dr. Aisha Al Suwaidi, Associate Professor, Earth Sciences department.  

 

The researchers were among 80 climate scientists from 20 countries who convened in Urbino, Italy, to participate in a wide range of disciplines that contribute to our understanding of paleoclimate and paleoenvironment, including geochemistry, cyclostratigraphy and paleobiology. The international program allowed the students to explore paleoclimate data and discuss their research with some of the leading scientists in the field and other PhD researchers. 

 

In the 2024 edition, participants explored a range of topics including biogeochemical cycling, paleoclimatology, paleoenvironment, paleoceanography, cyclostratigraphy, and deep-time climate modeling, including Cretaceous Ocean Anoxic Events, Paleocene-Eocene hyperthermals, the Greenhouse-Icehouse transition, and Neogene and Quaternary climate dynamics.  

 

The USSP program included lectures, symposia, and field trips organized and delivered by Professor Simone Galeotti, the University of Urbino, USSP co-director, and international climate scientists, whose research focuses on past climate dynamics, with a special emphasis on long-term carbon cycling and its implications for present and future climates. 

 

Painkal’s research focuses on the Late Triassic Carnian Pluvial Episode (CPE), a critical climate transition in Earth’s history marked by biotic changes, significant disruption of the carbon cycle, and shifts in climate from arid to wet and humid conditions much more similar to our modern climate. Through the utilization of multiple proxies, she seeks to constrain the timing and determine the potential mechanisms driving the event while also understanding the associated responses and recovery processes. 

 

Ghoshal is investigating biosphere changes in the Paleo-Antarctic during the Late Triassic (~230 million years ago). His research is primarily focused on the application of sedimentology and geochemistry, including biomarkers, to understand the evidence of wildfires in the Paleo-Antarctic circle during a relatively arid period in Earth’s history.   

 

First held in 2004, the USSP program is a hub for the international community studying natural climate variability, attracting early-career climate scientists and top researchers from around the world. 

 

Dr. Aisha Al Suwaidi said: “Khalifa University is at the forefront of innovative research in Earth Sciences, focusing on critical areas such as paleoclimatology, climate dynamics, and biogeochemical processes. The Earth Sciences department is dedicated to understanding past climate changes and their implications for the future. By participating in the USSP program, the two researchers are not only contributing to the global knowledge base but also acquiring the skills to address pressing environmental challenges, fostering a new generation of scientists committed to sustainability and climate resilience.”  

The diverse lectures, symposia, and exercises helped participants in assessing research goals and objectives, shedding light on the existing methodologies in deep-time research. This internship is expected to encourage more robust findings in Geoscience, Paleoclimate and related disciplines, enhancing academic portfolio.

Discover innovations in wastewater treatment—listen now!

Researchers at Khalifa University have found the membranes with specially-engineered nanomaterial additives are effective in removing a range of contaminants in industrial wastewater due to their synergistic adsorptive-catalytic as well as separation properties.  

 

The research team led by Dr. Linda Zou, Professor, Civil and Environmental Engineering have synthesized three morphologies of the material molybdenum disulfide (MOS2) — nanospheres, nanoplatelets, and nanosheets – as potential for water treatment applications. When incorporated with the biopolymer chitosan membranes, these nanomaterials contributed to the better removal of heavy metal contaminants, reduced fouling, higher water flow, while making the membrane structure more stable. 

 
The study, which highlights the importance of carefully choosing the right nanoparticle shape when fabricating the polymer membranes was published in the article titled ‘Effect of different MoS2 morphologies on the formation and performance of adsorptive-catalytic nanocomposite membranes’, in Nature NPJ Clean Water. Dr. Zou is the lead corresponding author, and the co-authors include Delal E. Al Momani, and Fathima Arshad from the Department of Civil Infrastructure and Environment Engineering and Research & Innovation Center for Graphene and 2D Materials (RIC2D), along with Inas Taha and Dalaver H. Anjum from the Department of Physics. 

 

The MoS2 particles also had a catalytic effect, creating reactive chemical species that further helped break down and remove contaminants including dyes, organic molecules, and pathogens in wastewater, emerging as efficient membrane technology for hazardous substances.  

 

Dr. Linda Zou

“Research at Khalifa University has opened up new possibilities for incorporating specifically designed 2D nanomaterials into polymer membranes to enhance water treatment capabilities.”

— Dr. Linda Zou, Professor at Department of Civil Infrastructure and Environmental Engineering, KU

Part of a family of two-dimensional materials, MoS2 is a promising nanomaterial for water treatment applications for its ability to accelerate the catalysis of hydrogen peroxide (H2O2) to help break down organic pollutants in water. MoS2 can also capture and remove heavy metal contaminants and can be easily integrated into composite materials, which improves the efficiency of wastewater treatment even further. Wastewater resulting from industries such as textile/leather, petroleum/refineries, paint, pesticides, and metal smelting commonly presents with a complex composition of organic contaminants and heavy metals, both requiring removal during the treatment process. 

 

Dr. Linda Zou said: “Research at Khalifa University has opened up new possibilities for incorporating specifically designed 2D nanomaterials into polymer membranes to enhance water treatment capabilities. Such advances in nanotechnology which enable the precise control of nanomaterial size, structure, and properties and nanomaterial-enhanced adsorptive-catalytic membranes, like those using graphene oxide (GO) or MoS2, have demonstrated impressive abilities to remove heavy metal contaminants from water.”
