The materiality exhibited by manmade polymers currently relies on simple chemical bonds and the sequence order taken by molecules in the polymer chain. We now no longer need to rely on fate to determine such materiality with this new technique for precisely defining polymer-chain order. This system uses highly specific 'grabber' ends on each molecule that bond with only one type of 'pin' end on another molecule.
A test that inexpensively monitors the safe storage of industrial carbon dioxide gas emissions in carbon capture and storage technology is to be used at a $5 million test site in Canada.
HRL Laboratories, LLC, has made a breakthrough in metallurgy with the announcement that researchers at the famous facility have developed a technique for successfully 3-D printing high-strength aluminum alloys that opens the door to additive manufacturing of engineering-relevant alloys.
Chemists at the Nagoya Institute of Technology report a metal-free method to control cationic polymerization that provides a new framework for higher quality industrial polymers. The reaction depends on weak halogen bonding and the addition of a small amount of ammonium salt to produce long, homogeneous polymers. The study can be read in Chemistry - A European Journal.
The cyber team led by Dr. Mordechai Guri, head of research and development for BGU's Cyber Security Research Center (CSRC), shows how IR can be used to create a covert communication channel between malware installed on an internal computer network and an attacker located hundreds of yards outside or even miles away with direct line of sight. The attacker can use this channel to send commands and receive response messages.
Scarce metals are found in a wide range of everyday objects around us. They are complicated to extract, difficult to recycle and so rare that several of them have become "conflict minerals" which can promote conflicts and oppression. A survey at Chalmers University of Technology now shows that there are potential technology-based solutions that can replace many of the metals with carbon nanomaterials, such as graphene.
A step towards new 'beyond lithium' rechargeable batteries with superior performance has been made by researchers at the University of Bath.
Researchers are looking at advanced materials for roads and pavements that could generate electricity from passing traffic. Engineers from Lancaster University are working on smart materials such as 'piezolectric' ceramics that when embedded in road surfaces would be able to harvest and convert vehicle vibration into electrical energy.
PNNL researchers have measured the forces that cause certain crystals to assemble, revealing competing factors that researchers might be able to control. The work has a variety of implications in both discovery and applied science. In addition to providing insights into the formation of minerals and semiconductor nanomaterials, it might also help scientists understand soil as it expands and contracts through wetting and drying cycles.
What affects almost everything made of metal, from cars to boats to underground pipes and even the fillings in your teeth? Corrosion -- a slow process of decay. At a global cost of trillions of dollars annually, it carries a steep price tag, not to mention, the potential safety, environmental and health hazards it poses.
