Emulsion Formation using corona discharge and electrohydrodynamic pumping
Project ID: D2020-22 Background Making water-in-oil emulsions often requires high pressure, ultrasonication, or sensitive inversion techniques that may still only result in a semi-stable colloid. In addition to emulsion shelf life, these techniques have drawbacks, such as having high-energy consumption and narrow/sensitive production parameters, needing...
Selective recovery of polypropylene (and polyethylene) from mixed plastic wastes
Project ID: D2021-43 Background Polypropylene (PP) is a thermoplastic polymer used in packaging materials, consumer goods, automotive components, and medical devices. It is difficult to recover PP from mixed plastic waste streams; PP has a similar density to polyethylene (PE) and cannot be selectively separated from PE via the sink-float methods...
Production of polyesters from bio-based feedstocks
Project ID: D2014-20 Background Polyesters are often used to make fabric for clothing and other household items. Manufacturers of polyesters typically use non-renewable fossil fuels as the feedstock, resulting in an emission intensive and environmentally harmful process. On the other hand, furfural is a platform chemical and bio-based feedstock derived...
Constrained geometry catalysts for the production of polymers
Project ID: D2009-89 Background Polymerization reactions are used in industry to make widely used products, such as polyolefins. There has been an interest in improving control over polymer tacticity and co-polymerization, leading to the development of Constrained Geometry Catalysts (CGCs). The CGCs form complexes with a pi-bonded moiety bridged...
Connectors for joining aluminum plates
Project ID: D2018-49 Background Several approaches have been taken to join aluminum plates or sheets. However, each has disadvantages. For example, resistance spot welding of common alloys can cause expulsion, distortion, short electrode life, and the formation of voids and cracks. Friction stir welding is limited in that it requires equipment...
High yield production of fuels and petro- or oleo-chemical precursors from vegetables oils/liquid feedstocks in a continuous-flow pyrolysis reactor
Project ID: D2016-39Background Pyrolysis of oil seeds and microalgae has the potential to displace petroleum-derived fuels. Current methods require batch processing which produces low yield of liquid products, contamination from secondary reactions, and causes buildup inside the reactor. Therefore, there is a need to improve the efficiency of pyrolysis...
Homogenous and Reusable Superacid Polymer Catalyst for the Synthesis of 5-Hydroxymethylfurfural from Glucose
Project ID: D2018-18Background Combinations of Brønsted and Lewis acid catalysts are generally used for the production of 5-hydroxymethylfurfural (HMF) from glucose. However, reutilization of these catalysts is challenging due to their solubility in reaction medium. Heterogeneous catalysts containing both types of acid sites are not usually...
Ultrastable Silver Nanoparticles
Project ID: D2014-05Background Silver nanoparticles have shown huge technological promise in wide variety of applications due to their superior optical properties, bioactivity, and diversity of chemical and photochemical properties. However, the main challenge with silver nanoparticle is its chemical instability to oxidation, i.e. tarnishing, which...
Cost- and Energy-Efficient Device for De-watering Microalgae Using Stimuli-Sensitive Hydrogels
Project ID: D2016-01IP Status: US Patent 10,077,422Invention Description: Currently, a major hurdle for commercial-scale production of fuels and other products from microalgae is recovering algal biomass from growth media with minimal cost and energy input. When cultivated in open raceway ponds, microalgae concentrations are very low – typically...
Renewable Alternatives to Petroleum-Derived Products: Novel Approach Creates Nylon-12 and -13 Precursors from Lipids
Project ID: D2014-06 Invention Description: Invention relates to a new olefin cross-metathesis approach for making C12 and C13 amino esters from oleic acid (or alkyl esters) originating from lipids. The method allows direct conversion of the widely abundant natural fatty acid oleic acid into synthetic precursors or nylon-12 and nylon-13 in half the...
