Imagine pouring a glass of ice water and having the ice cubes remain unchanged hours later, even under a broiler's heat or in the very back corner of the freezer.That's fundamentally the surprising discovery recently made by an international group of researchers led by an electrical engineering professor at Duke University in a paper published online inNature Matter. But instead of a refreshing mixture of H2O in a pint glass, the researchers were...

Better batteries that charge quickly and last a long time are a brass ring for engineers. But despite decades of research and innovation, a fundamental understanding of exactly how batteries work at the smallest of scales has remained elusive.

Expanding its offering of mid-power UV LEDs in the 365nm wavelength range, Vishay Intertechnology announces the VLMU1610-365-135 with a silicone lens in a compact 1.6x1.6x1.4mm surface-mount package. The VLMU1610-365-135 is designed to provide a reliable, energy-saving replacement for mercury lamps and delivers an exceptionally long lifetime for medical, industrial and printing applications.

Indium Corporation's reclaim and recycle program is now offering customers credit for their solder pot dross and contaminated solder. Returned solder, used in wave and other soldering processes, can be put through Indium Corporation's state-of-the art electrolytic recycling processes that removes both organic and metallic impurities from contaminated tin-lead and lead-free solder and solder dross.

It is now feasible to make a prized material for spintronic devices and semiconductors - monolayer graphene nanoribbons withzigzag edges.Miniscule ribbons of graphene are highly sought-after building blocks for semiconductor devices because of their predicted electronic properties. But making these nanostructures has remained a challenge. Now, a team of researchers from China and Japan have devised a method to make the structures in the lab. Thei...

Associate Professor Igor Aharonovich and Professor Milos Toth, photonics researchers at University of Technology Sydney, in collaboration with scientists at MIT, have discovered some of the brightest quantum emitters ever recorded – in hexagonal boron nitride (hBN), a honeycomb structure that mimics graphene. Instead of carbon atoms, however, it is an alternating array of boron and nitrogen atoms.

A new generation of thermally conductive two-part epoxy adhesives, have been introduced from Intertronics, as the latest applications in energy and electrical engineering require highest ever levels of thermal conductivity.

A team of scientists led by the Department of Energy's Oak Ridge National Laboratory has developed a novel way to produce 2D nanosheets by separating bulk materials with nontoxic liquid nitrogen. The environmentally friendly process generates a 20-fold increase in surface area per sheet, which could expand the nanomaterials' commercial applications."It's actually a very simple procedure," said ORNL chemist Huiyuan Zhu, who co-authored a study pub...

The old rules don't necessarily apply when building electronic components out of two-dimensional materials, according to scientists at Rice University.The Rice lab of theoretical physicist Boris Yakobson analysed hybrids that put 2D materials like graphene and boron nitride side by side to see what happens at the border. They found that the electronic characteristics of such "co-planar" hybrids differ from bulkier components.

Researchers from North Carolina State University and the U.S. Army Research Office have developed a way to integrate novel functional materials onto a computer chip, allowing the creation of new smart devices and systems.
