Enhanced utilization/conservation of water using cellulose gels

Technology Overview

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.

Antifogging glass technology to tackle dirt and grim on glass

Technology Overview

The fabrication of (titanium dioxide) TiO2 coatings deposited by e-beam evaporation was achieved, with the ability to induce the production of self-cleaning superhydrophilic glass without the need for UV irradiation. After being annealed at 500 °C, the non-porous films exhibited radiation-free superwetting behavior. The superhydrophilic and antifogging
properties, which can be reactivated by a thermal treatment or prolonged through UV exposure, confirmed the excellent potential of these materials for self-cleaning application, both outdoors and indoors. The deposition of a 20 nm layer did not alter the optical and mechanical properties of the glass. In addition, film adhesion to the substrate and photocatalytic activity proved to be very effective. The prepared 20 nm coating (20-TiO2-GLASS) shows enhanced antifogging properties compared to bare glass and the commercial self-cleaning glass

Multi-chamber reactor for converting waste oil into biofuel

Technology Overview

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.

Innovative method to obtain metal and metal oxide nanostructures

Technology Overview

In this invention, a robust method for fabricating high-aspect-ratio structures through a self-folding process of planar thin films is developed. It relies solely on three standard microfabrication steps, lithography, etching, and sputtering processes, provides the flexibility to position the spalled structures
according to the application requirements, and is fully compliant with CMOS fabrication standards. This method has been successfully demonstrated for metal-oxides and metals. The width of the fabricated structures is dependent on the thickness of the film deposited by sputtering, where structures as small as 20 nm in width have been obtained.

Artificial Materials for Effective Electromagnetic Wave Absorption

Technology Overview

A gradient 3-dimensional (3D) honeycomb metamaterial structure is fabricated, and its structure parameters were optimized and fabricated by using 3D printing technology. Nanocomposites with carbon nanotubes and magnetic nanoparticles have been prepared and coated on the gradient 3D structure. The titled angle has a dramatic effect on the RL and the reduced mismatch between air and 3D meta-absorber should account for the enhanced performance. The gradient 3D meta-absorber has features of high performance and lightweight, which could find applications in many fields, especially in aerospace and military application where lightweight materials are preferred.

Steering of catalyst structures towards coke-free catalyst

Technology Overview

Dry reforming of methane (DRM) is an endothermic catalytic process (CH4 + CO2 2 CO + 2 H2) that can produce clean and green H2 fuel and synthesis gas (CO/H2). The syngas produced can be utilized for the production of fuels and high value-added chemicals such as methanol, dimethyl ether, acetic acid, and other oxygenated chemicals and long chain hydrocarbons via Fischer-Tropsch (FT) synthesis. DRM is also an attractive alternative for CO2 utilization and recycling, which consequently mitigates global warming as it uses two main greenhouse gases. However, it has not been industrialized yet due to the lack of development of robust catalysts that can sustain coke-free operation and high resistance to metal sintering at high temperatures. Ni-based catalysts present an economically viable alternative compared to noble metal-based catalysts. However, they suffer mainly from carbon deposition, which ultimately leads to catalyst deactivation. The Ni-supported catalysts prepared in the present invention showed excellent stability and carbon formation reduction.
