By Michael Langley Tim Briggs has built a career at Sandia National Laboratories tearing and breaking things apart with his team of collaborators. Now, he’s developed a fracture-testing tool that could help make everything from aircraft structural frames to cellphones stronger. Briggs has filed a patent for a device associated with bonded structural composite materials…

ACS Materials Letters Exposure to some odorless, colorless and tasteless gases, such as nerve agents, can be toxic or even lethal. And having the ability to detect other types of vapors could save people from eating spoiled or rotten food. Easy-to-use portable devices could, therefore, go a long way toward protecting the public. Now researchers…

Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory, Stony Brook University (SBU) and other collaborating institutions have uncovered dynamic, atomic-level details of how an important platinum-based catalyst works in the water gas shift reaction. This reaction transforms carbon monoxide (CO) and water (H2O) into carbon dioxide (CO2) and hydrogen gas (H2) — an…

It provides high elongation, superior shielding, strong adhesion, durability and conductive performance. Its unique siloxane matrix, enabled by Dow’s backward integration of raw materials, provides novel electrical and…

  Marking a major achievement in the field of spintronics, researchers at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and Yale University have demonstrated the ability to control spin dynamics in magnetic materials by altering their thickness. The study, published today in Nature Materials, could lead to smaller, more energy-efficient electronic devices. “Instead…

ShAPE (Shear Assisted Processing and Extrusion), from Pacific Northwest National Laboratory, is a revolutionary new manufacturing process for a new generation of high-performance materials. Because ShAPE is radically different from conventional extrusion methods — eliminating the need for heating and melting to alloy and form metal products — it offers a scalable pathway to entirely…

A new carbon fiber material could bring cost and performance benefits to the wind industry if developed commercially, according to a study led by researchers at Sandia National Laboratories. Wind blades containing carbon fiber weigh 25% less than ones made from traditional fiberglass materials. That means carbon fiber blades could be longer than fiberglass ones…

The M2R2 CLLBC Multimode Radioisotope Identification Detector (RIID), from the Kromek Group, is the first product of its kind incorporating the dual-mode, gamma-neutron sensitive CLLBC crystal. This next-generation material, developed by RMD, previously won this award and this is the first instrument to move the technology from material to product. The M2R2 is an all-in-one,…

Nicca Chemical Co.’s NEOSEED NR-8800, silicone-based water repellent (DWR) for textiles, provides breakthrough performance as a sustainable, durable water repellent option in the textile market, which is moving away from Perfluoro chemicals (PFC). It is the first product on the market which embraces silicone technology as a main component resulting in a fine performance balancing…

By Stephanie G Seay, ORNL In the quest for advanced vehicles with higher energy efficiency and ultra-low emissions, Oak Ridge National Laboratory researchers are accelerating a research engine that gives scientists and engineers an unprecedented view inside the atomic-level workings of combustion engines in real time. The new capability is an engine built specifically to…

Group14 Technologies, a global provider of silicon-carbon composite materials for lithium-ion markets, today announced it has secured $17 million in Series B funding led by SK Materials, a manufacturer of special gases and industrial gases, with participation from returning investor OVP Venture Partners. Group14 will use this operating capital to scale production to meet the…

Wouldn’t it be nice to have resins that can be tough, resilient and flexible all at the same time? That’s exactly the type of characteristics that ENGAGE Polyolefin Elastomers (POEs), from Dow Packaging and Specialty Plastics, bring to the table. ENGAGE POEs serve as a bridge between rubber and plastic chemistries to inspire new design…

By Chris Cogswell, customer consultant and Kane Gu, product manager Elsevier When it comes to the materials we use in industry and daily life, we’re facing a range of new challenges — from shortages to environmental issues, to the need for new materials to support technology innovation. On top of this, consumer awareness is on…

401 Tech Bridge today announced Canapitsit Customs, Nautilus Defense and TxV Aerospace Composites as the winners of the Materials Innovation Challenge. 401 Tech Bridge will provide $105,000 ($35,000 per project) to the University of Rhode Island College of Engineering. Project funding will support collaboration with URI’s Dynamic Photomechanics Laboratory, led by Mechanical, Industrial and Systems…

In the ongoing quest to build a better battery, researchers used the Canadian Light Source (CLS) at the University of Saskatchewan to identify the potential of using polymer composites as electrode matrices to increase the capacity of rechargeable lithium-ion (Li-ion) batteries. “The composition of the adhesive and conductive framework for batteries hasn’t changed in years,”…

Binary Solvent Diffusion (BSD) enables the production of new materials with better performance and structure control while reducing costs, enhancing properties and allowing direct integration of devices. It represents a new paradigm for producing functionally designed supercrystals with significant flexibility in control of materials architecture and property as well as direct integration of nanoelectronic devices…

Ordinary metallic conductors have electrical resistance, which dissipates electrical power as heat when a current flows through them. Although resistance reduces slightly as the temperature is lowered, even at close to absolute zero there is significant resistance. When a superconductor is cooled, an abrupt change occurs at its critical temperature whereby all resistance suddenly disappears.…

ACS Applied Materials & Interfaces Although most of the planet is covered by water, only a fraction of it is clean enough for humans to use. Therefore, it is important to recycle this resource whenever possible. Current purification techniques cannot adequately handle the very hot wastewater generated by some industries. But now, researchers reporting in…

By Julie Chao Understanding how matter interacts with light – its optical properties – is critical in a myriad of energy and biomedical technologies, such as targeted drug delivery, quantum dots, fuel combustion and cracking of biomass. But calculating these properties is computationally intensive, and the inverse problem – designing a structure with desired optical…

 By Theresa Duque We rely on water to quench our thirst and to irrigate bountiful farmland. But what do you do when that once pristine water is polluted with wastewater from abandoned copper mines? A promising solution relies on materials that capture heavy metal atoms, such as copper ions, from wastewater through a separation process…

Graphene is a flat hexagonal lattice of carbon atoms, just one atom thick. It is a form of carbon related to carbon nanotubes and buckyballs (C60). Although it has always occurred naturally, it is only recently that it has been isolated and it’s individual properties examined. It is now known that graphene has exceptional electrical,…

Non-destructive testing (NDT) is a general term for any method that determines material properties without damaging the object being tested. Most commonly it is used to measure cracks and pores in materials that may be subject to a brittle failure. Because these defects could act as crack initiation sites, the size and frequency of the…
