"We're trying to generate polymers that interact with microbes in a very different way than traditional antibiotics," says James Hedrick, a materials scientist at IBM's Almaden Lab in San Jose, California.
Optimization of reaction conditions has led to a highly efficient procedure to generate polymers with controlled molecular weight (Mw), ranging from 10,000 to above 500,000 depending on the requirements of the desired applications.
The obtained results indicate that a process involving a single enzymatic step could be adequate to decrease the effluent COD and to generate polymers with potential applications in the food and pharmaceutical industries.
There are many different synthetic techniques used in the sol-gel process to generate polymer-silica hybrid materials.
A year later, he took a permanent position at NIST as a research chemist in the same division and spent the next 3 years developing methods to generate polymers and test their flammability.
Different types of polymer are possible, but, experimentally only heat has been shown to generate polymers in vitro consistent with ex vivo pathological specimens.
The primary hypothesis that we present here is that composomes and their functions evolved by means of a series of SUMIs that endowed prebiotic ecologies with unprecedented ways: to control ion fluxes and osmotic pressure gradients; to store carbon, nitrogen and phosphate, and to store and release energy; to select interacting molecules; to catalyze reactions and to generate polymers.
This was then followed with an isothermal amplification of the desired region with biotin-deoxynucleotides (dNTPs) to generate polymers of biotin/DNA which then served as substrates for the HRP/TMB colorimetric reaction and therefore indicating the presence of a HDMR.
His team's research focuses on a new approach to generating polymer membranes with three-dimensional porosity.
The two latter reactions required the prior deprotonation of the imidazolium salt units with a strong base to successfully generate polymer-supported N-heterocyclic carbenes, referred to as poly(NHC s.
