PolymPart -- Crude oil is sticky stuff and often clogs filter membranes and other equipment used in the oil and gas industry. To address this problem, scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory have developed a novel approach, which will prolong the lifetime of key industrial equipment. The new invention consists of a type of coating that produces thin films of water-loving, oil-repelling molecules on the surface of filter membranes. These metal oxide molecules grab onto any loose water atoms while resisting oil. To scientists, these twin properties are known as hydrophilicity and oleophobicity. "One of the best ways to clean oily water is with membranes," said Seth Darling, Director of the Institute for Molecular ...

The PVT-6000 Polymer PVT Tester has been specifically designed for users interested in analyzing the volume of plastics as a function of both temperature and pressure in molten and/or solid states. During the test, specific volume is achieved following the formation of the polymer through constant or stepwise pressure and temperature. The data acquired during the test is then applied to the Moldex3D injection molding simulation to determine the accuracy and production stability of the analysis. Once the Moldex3D injection molding has been optimized, work efficiency and polymer production quality increases while simultaneously reducing the occurrence of product defects that occur during injection molding processes. Some product defects that are greatly ...

PolymPart: UPTON, NY--Scientists from the Center for Functional Nanomaterials (CFN)--a U.S. Department of Energy (DOE) Office of Science User Facility at Brookhaven National Laboratory--have dramatically improved the response of graphene to light through self-assembling wire-like nanostructures that conduct electricity. The improvement could pave the way for the development of graphene-based detectors that can quickly sense light at very low levels, such as those found in medical imaging, radiation detection, and surveillance applications. Graphene Graphene is a two-dimensional (2-D) nanomaterial with unusual and useful mechanical, optical, and electronic properties. It is both extremely thin and incredibly strong, detects light of almost any color, ...
