In this paper, we reviewed researches about the titanium nitride (TiN) and titanium carbide (TiC) single and multilayer coatings. These coatings were deposited by the plasma assisted chemical vapor deposition (PACVD) technique. Plasma-based technologies are used for the processing of thin films and coatings for different applications such as automobile and aerospace parts, computer disc drives,...
World population growth and requirement to global food security, application of genetic engineering and utilization of transgenic organisms have made more important. Using this technology, without regarding to its risks, can cause loses to environment. To generate transgenic organisms, selection systems are applied that cause to selective growth of transformed cells. Antibiotic resistance genes...
one of the applications of nanotechnology is use of carbon nanotubes for the targeted delivery of drug molecules. to demonstrate the physical and chemical properties of biomolecules and identify new material of drug properties, the interaction of carbon nanotubes (cnts) with biomolecules is a subject of many investigations. cnts is a synthetic compound with extraordinary mechanical, thermal, el...
Kinase-mediated resistance to antibiotics is a significant clinical challenge. These enzymes share a common protein fold characteristic of Ser/Thr/Tyr protein kinases. We screened 14 antibiotic resistance kinases against 80 chemically diverse protein kinase inhibitors to map resistance kinase chemical space. The screens identified molecules with both broad and narrow inhibition profiles, provin...
polyurethanes (purs) are polymers that can be generated by a step-growth polyadditionreaction of diisocyanates with polyols. the number of well-developed chemical procedures applicable to theirmanufacture, and the diversity of chemical structures in which polyurethanes can be built, account for thewidespread use of these materials in the last few decades for both domestic and technical applicat...
INTRODUCTION Like all living things, cattle ticks have the ability to overcome adversity in order to survive. They can adapt genetically over time so that they and their offspring build up resistance to the normal tick treatments used. This is known as tick acaricide (chemical) resistance. The prolonged or incorrect use of tick chemicals can lead to resistance in ticks, enabling the ticks to to...
