Lowers manufacturing cost while maintaining desirable physical properties
Thermoplastic, also known as thermosoftening plastic, is a polymer that becomes pliable or moldable above a specific temperature, and returns to a solid state upon cooling. The developed thermoplastic sulfur-polymer composite is comprised of a thermoplastic polymer, such as polyethylene and polystyrene, and a sulfur element. The thermoplastic polymer is a polymer matrix with the sulfur filler is dispersed in the polymer matrix.
Providing access to fresh water in areas of scarcity
Water is one of the most important resources in the world, however there is scarce access to fresh water in some locations. The developed device can be used for collecting water from the atmospheric moisture with no without energy input except for solar radiation. The device is comprised of a water absorbing material, a protection wall and a water container. When the water absorbing material is below phase separation temperature, hydrogen bonds are formed with water molecules resulting in the absorption of water from the air.
Enhancing the structure of molybdenum disulfide
Sulfur-containing compounds are by-products from oil and gas production. Molybdenum disulfide is the preferred catalyst for hydro-desulphurization, which is the catalytic chemical process to remove sulfur from natural gas or other refined chemical products. However, molybdenum disulfide is limited to the surface area of the material. The developed process expands the surface area of the material by increasing the porosity and internal cavities of the material.
Nanotips with desirable apex atomic structures
The developed method of fabricating a super nano ion-electron source can lead to improved nanotips for applications in nanotechnology, particularly in scanning probe microscopy and electron microscopy. The method involves placing an assembly of precursor tip with an apex and a shank and a heating metal ring in a field ion microscope chamber, applying a direct current to heat the metal ring, applying an electrical field to the precursor tip, and monitoring the evolution of the tip apex until sharpened to a desirable structure.
A new binder-free catalyst and a process to produce a designed zeolite-based catalyst with high selectivity. The novel feature of this technology is the use of only catalyst active materials and therefore producing high-quality catalyst through a cost-effective process.

Smart sensors for in-situ measurement for monitoring and fracture mapping during and after geological hydro-fracturing. The sensors records and provides near to real-time data on temperature, pressue, chemical composition, etc. A record set of these sensors can be embedded in the proppant and provide status of the well. All data and information within the fractured rock and any information changes is transmitted wirelessly.

Enhanced filters designed to alleviate pharmaceutical pollution of water
Pharmaceutical compounds are emerging contaminants in the water supply due to increasing use throughout the world. The developed photo-regenerable filters are designed to remove pharmaceutical compounds and other contaminants from water. The filter is comprised of carbon nanotubes and high surface area titanium dioxide nanospheres, in which the high surface area titanium dioxide nanospheres are dispersed in the carbon nanotubes.
Enhanced utilization/conservation of water using cellulose gels
Cellulose is the most abundant biopolymer that can be extracted inexpensively from plants and other organisms. The developed cellulose gel compositions are prepared by modifying native cellulose to generate a material with enhanced water absorption and retention properties. The material is produced through the regeneration of cellulose in aqueous polyethylene oxide. The material has been demonstrated to hold twenty times its weight.
Multi-chamber reactor for converting waste oil into biofuel
Biodiesel is an important alternative fuel that includes a fatty acid methyl or (ethel) esters produced from trigylcerides as the product of vegetable, lipid, animal, trapped grease, or recycled cooking oil. However, production of biodiesel is limited due to current production methods. The developed multi-chamber continuous tubular reactor for the transesterification of oil can improve production. The multi-chamber design operates in a helical flow pattern to enhance mass transfer and increase conversion.
Improved process of preparing pharmaceutical tablets
A gel material from structure-modified or processed cellulose combined with an active pharmaceutical ingredient can be used to improve the process of tablet production. The approach introduces a continuous process that can reduce labor, time, and cost of production. In addition, the approach results in an improved tablet with desirable properties.
