ORNL Story Tips: Pandemic impact, root studies, neutrons confirm, lab on a crystal and modeling fusion.
The research team directed by H. Shimomoto and E. Ihara in Ehime University synthesized pH-responsive dendronized polymers by C1 polymerization of dendron-containing diazoacetates, and demonstrated a unique pH-responsive behavior of the resulting polymers. These achievements will contribute to progress in the field of polymer chemistry and will allow us to develop new types of smart soft materials.
Simulations at Graz University of Technology refute earlier theories on long-range charge transfer between organic and inorganic materials.
Researchers have been working for decades on improving the anti-icing performance of functional surfaces and work published in AIP Advances investigates a unique nanostructure, modeled on moth eyes, that has anti-icing properties. Moth eyes are of interest because they have a distinct ice-phobic and transparent surface. The researchers fabricated the moth eye nanostructure on a quartz substrate that was covered with a paraffin layer to isolate it from a cold and humid environment.
Airplane wings and wind turbine blades are typically created using bulk polymerization in composite manufacturing facilities. They are heated and cured in enormous autoclaves and heated molds as big as the finished part. Frontal polymerization is a new out-of-autoclave method that doesn't require a large facility investment. Researchers at the University of Illinois Urbana-Champaign conducted a study pitting one process against the other to discover the pros and cons of each.
A team of researchers from Japan has demonstrated a light-based reaction that yields high numbers of the base chemical component required to produce bioactive compounds used in common industry products. They published their results on June 11, 2020 in Organic Letters.
An efficient in situ pathway to generate and attach oxygen functional groups to graphitic electrodes for supercapacitors by inducing hydrolysis of water molecules within the gel electrolyte.
It sounds like a magic trick: A highly charged ion penetrates several layers of a material. It creates a big hole in the top layer, but travels through the next layer without damaging it. This new technique can be used to modify surfaces with extremely hight precision.
More durable prosthetics and medical devices for patients and stronger parts for airplanes and automobiles are just some of the products that could be created through a new 3D printing technology invented by a UMass Lowell researcher.
The design of novel materials with superior characteristics by entropy stabilization is a very dynamic emerging research area in materials science. However, despite recent advances in entropy-stabilized metals and insulating ceramics targeted for structural applications, there is still a dearth of high-entropy semiconductors, which poses a major obstacle for the adoption of high-entropy materials in semiconducting functional applications. Our study aims to realize a novel class of the semiconducting entropy-stabilized chalcogenide alloys.
