Scientists at the U.S. Department of Energy’s Ames Laboratory were able to successfully manipulate the electronic structure of graphene, which may enable the fabrication of graphene transistors-- faster and more reliable than existing silicon-based transistors.
Eight Los Alamos National Laboratory innovations were selected as finalists for the 2017 R&D 100 Awards, which honor the top 100 proven technological advances of the past year as determined by a panel selected by R&D Magazine.
A new way of operating the powerful X-ray laser at the Department of Energy’s SLAC National Accelerator Laboratory has enabled researchers to detect and measure fluctuations in magnetic structures being considered for new data storage and computing technologies.
The American Physical Society has recognized Blair Ratcliff, an emeritus physicist at SLAC and Stanford University, with the 2017 Division of Particles and Fields Instrumentation Award “for the development of novel detectors exploiting Cherenkov radiation” – an advance that greatly enhanced BABAR’s capabilities and influenced the design of other experiments.
A science team at Berkeley Lab has precisely measured some previously obscured properties of a 2-D semiconducting material known as moly sulfide, which opens up a new avenue to applications. “That provides very important guidance to all of the optoelectronic device engineers. They need to know what the band gap is” in orderly to properly connect the 2-D material with other materials and components in a device, Yao said. Obtaining the direct band gap measurement is challenged by the so-called “exciton effect” in 2-D materials that is produced by a strong pairing between electrons and electron “holes” – vacant positions around an atom where an electron can exist. The strength of this effect can mask measurements of the band gap. Nicholas Borys, a project scientist at Berkeley Lab’s Molecular Foundry who also participated in the study, said the study also resolves how to tune optical and electronic properties in a 2-D material. “The real power of our technique, and an importa

Researchers at Columbia Engineering have developed a simple, low-cost, and environmentally sound method for fabricating a highly-efficient selective solar absorber (SSA) to convert sunlight into heat for energy-related applications. The team used a “dip and dry” approach whereby strips coated with a reactive metal are dipped into a solution containing ions of a less reactive metal to create plasmonic-nanoparticle-coated foils that perform as well or better than existing SSAs, regardless of the sun’s angle.
With this breakthrough, the high-performance polymer now could theoretically be used in any shape, size, or structure. And not just within the aerospace industry. The same material can be found in scores of electronic devices, including cell phones and televisions.
The results of the fifth and latest Collaborative Materials Exercise of the Nuclear Forensics International Technical Working Group, a global network of nuclear forensics experts, will be discussed at the American Chemical Society’s national meeting in Washington D.C. on August. 24.
Using plants and trees to make products such as paper or ethanol leaves behind a residue called lignin, a component of plant cell walls. That leftover lignin isn’t good for much and often gets burned or tossed into landfills. Now, researchers report transforming lignin into carbon fiber to produce a lower-cost material strong enough to build car or aircraft parts.

Magnesium — the lightest of all structural metals — has a lot going for it in the quest to make ever lighter cars and trucks that go farther on a tank of fuel or battery charge.Magnesium is 75 percent lighter than steel, 33 percent lighter than aluminum and is the fourth most common element on earth behind iron, silicon and oxygen.
Plutonium has more verified and accessible oxidation states than any other actinide element, an important insight for energy and security applications.
Easily manufactured, rigid membranes with ultra-small pores provides to be ultra-selective in separating chemicals.
Scientists have pinpointed how a tiny protein seems to make the deadly Ebola virus particularly contagious.
Researchers have developed a new method for thawing frozen tissue that may enable long-term storage and subsequent viability of tissues and organs for transplantation. The method, called nanowarming, prevents tissue damage during the rapid thawing process that would precede a transplant.
From smart socks to workout clothes that measure exertion, wearable body sensors are becoming the latest “must-have” technology. Now scientists report they are on the cusp of using silk, one of the world’s most coveted fabrics, to develop a more sensitive and flexible generation of these multi-purpose devices that monitor a slew of body functions in real time.
Soldiering in arctic conditions is tough. Protective clothing can be heavy and can cause overheating and sweating upon exertion. And hands and feet can grow numb despite wearing such gear. To keep military personnel more comfortable and battle-ready in bitterly cold climes, scientists are now conducting research aimed at creating high-tech fabrics that heat up when powered and that capture sweat. These fabrics could also conceivably make their way to consumer clothing in the future.
The U.S. Department of Energy’s Argonne National Laboratory and United Scientific Supplies, Inc. are introducing high school students to nanoscience with a new hands-on product.
A new uranium-based metal-organic framework, NU-1301, could aid energy producers and industry.
