Simple Optical Sensor for Biodiesel Contaminant in Jet Fuel
Reference: PD 13070-03The Problem: In April 2010, contamination in jet fuel caused the throttles of two engines on a Cathay Pacific flight to stick while in flight and nearly caused the lives of 322 passengers and crew on board.  Such incident is just one of the examples of the dangers posed by cross contamination in the fuel. FAME, or biodiesel, has...

Plant derived nanoparticles for cosmetics and sunscreen
The TechnologyThere are numerous sunscreen and cosmetics products on the market today that contain nanoparticles (NP’s). These NP’s increase ultraviolet light absorption of the product and also allow the product to be spread more easily. Titanium dioxide (TiO2) and Zinc oxide (ZnO) are the most commonly used NP’s, and they are commonly found together...

English ivy nanoparticle production system
The Technology Nanoparticles have grown increasing popular for their industrial, health care, and cosmetic applications. Unfortunately, many of the methods of synthesis produce highly toxic byproducts. Researchers at the University of Tennessee initially discovered that English ivy rootlets produce nanoparticles that help the plants adhere to surfaces...

A New Oxyma Derivative for Amide-forming Reactions in Water
Reference: PD 12110 Background In amide-forming reactions with R-amino acids, the use of a coupling additive such as benzotriazole derivatives (e.g., 1-hydroxy-7-azabenzotriazole (HOAt) and hydroxybenzotriazole (HOBt)) is essential to suppress racemization and improve the efficacy of peptide synthesis. Oxyma, ethyl 2-cyano-2-(hydroxyimino)acetate,...

Hydrogel coated nasal cannula
The TechnologyTwo of the main challenges in nasal-based respiratory therapy are providing a soft contact with the nasal cavity and creating a seal between the cannula and the nasal cavity. Long term users often complain of dry or bleeding nasal cavities. This irritation can in turn lead to infection. In pediatric and geriatric patients, there is a need...
