Nanoparticles as Catalyst for Formation of Rigid Organic Polymers with Controlled Polymerization
Overview Polybenzoxazole (PBO) fibers have usually been made by condensing diaminobenzene diol and terephthalic acid with polyphosphoric acid (PA), which serves as both solvent and catalyst. The use of PA, however, causes the PBO fibers to be contaminated with PA units. We have invented a nanoparticle (NP)-based catalytic method to synthesize functional...

𝜷‐Lactamase-Responsive Degradable Hydrogels
Overview Antibiotic-resistance poses a serious public health problem. We have developed a hydrogel (hydrated polymer network) that is sensitive to β-lactamases, a class of enzymes released by a variety of harmful bacteria. In the presence of β-lactamases, the hydrogel degrades, releasing the therapeutic agent it contains. Market Opportunity The...

Cost-Effective Single-Step Process for the Catalytic Conversion of Methane to Methanol/Formaldehyde
Unmet Need: Currently there is no technology available in the market capable of producing Dimethyl Ether (DME) from methane in a single reactor. DME is an attractive substitute for diesel due to its high cetane number, which is a measure of its ignitibility in compression ignition engines. In addition, DME’s quiet combustion and inability to form...

Peptide Antagonists Prevent Pulmonary Oxygen Toxicity
Current State of the ArtPulmonary oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen at elevated partial pressures. Oxygen toxicity is a concern for scuba divers, those on high concentrations of supplemental oxygen (particularly premature babies), and those undergoing hyperbaric oxygen therapy. Problems...
