New Hydrometallurgical Processes in the Recovery of Strategic Metals

Due to the increased global demand of strategic metals – rare earths, lithium, tantalum, niobium and uranium – new processes are being developed to recover them from low-grade polymetallic ores.  An accurate description of the physicochemistry involved in the solvent phase, in the feedstock, and at the interface is a prerequisite to simulate solvent extraction processes and to develop new, efficient, and selective extractant molecules.

Fragment-based Lead Discovery (FBLD): A Powerful Method for Drug Discovery

While typical high throughput screening relies on libraries containing a million of drug-sized molecules, FBLD relies on smaller libraries of perhaps a few thousand small molecular fragments, generally less than 300 Daltons. Because the FBLD fragments are so small, the techniques to find and validate them must be sensitive and specific. These include biophysical methods such as NMR, SPR, and X-ray crystallography. Moreover, it can be difficult to improve the potency of a fragment from a millimolar hit to a nanomolar drug lead.  Despite these challenges, FBLD is now widely embraced by the pharmaceutical and biotech industries, as well as academia. The approach is responsible for putting at least 30 drugs into clinical trials, including the anticancer drug vemurafenib, approved in 2011.   Read More …

Problems Associated with Misapplication of Pesticides in Agriculture

Many problems have been associated with the misapplication of pesticides in agriculture such as, soil infertility, chemical pollution of land and water, pesticide poisoning, pest resistance against chemicals and other side effects to non-target organisms.  In order to mediate those environmental and public health issues, research is being done aiming at developing novel strategies that are more environmental-friendly. In this sense, understanding how plant chemicals mediate plant-insect interactions and determining their identity is a highly valuable resource to manipulate insect behavior in the field and therefore manage their population.     Read More…
