where polymers interact with a layer of fluid between two different surfaces. The authors acknowledge funding from the Foundation for Science and Technology, Portugal. The American Chemical Society ...

When you first enter a new world, you can either spawn near a structure or find one while exploring any of the three dimensions. While finding some can be quite easy, others are extremely hard to ...

"After the polymer is formed, there's not a whole lot holding the structure together," Dichtel said. "So, when we put it in solvent, the crystal dissolves, but each 2D layer holds together. We can ...

Nov. 12, 2020 — Chemists have determined the molecular structure of a protein found in the SARS-CoV-2 virus. This protein forms a cation-selective channel and plays a key role in the virus's ...

The international team describes their results and the underlying molecular mechanism in Cell Metabolism. Ergothioneine is a natural compound found in certain fungi such as oyster or shiitake ...

A structure of the Pd-based initiators was devised leading to success in improving their activity for C1 polymerization. For example, it is now possible to prepare high molecular weight polymers ...

ORNL’s invention may change plastic’s environmental fate by rearranging polymeric building blocks to customize the properties of plastics. Molecular subunits link to produce polymer chains that can ...

Chemical structure of Kevlar. Image credit: Wikimedia Commons “When one applies a light force to the polymer, it is extremely flexible, but if more force is applied the material becomes more ...

While the polymer is not adhesive when made that way, his lab was able to chemically re-engineer its structure to now deliver stronger adhesion than the common petroleum-derived, nonbiodegradable ...

The polymer used for the fabrication of the membranes was CA (average M n ∼ 50,000, Sigma-Aldrich, Spain). The green solvent was DMC (Merk, Spain). The commercial nanoporous fillers used were Zeolite ...
