Researchers at Oak Ridge National Laboratory, Oak Ridge, Tenn., demonstrated that stainless steel and other metal alloys coated with hexagonal boron nitride, or hBN, exhibit non-stick or low-friction qualities along with improved long-term protection against harsh corrosion and high-temperature oxidation in air.
In powder manufacture, particle size distribution, known as classification, categorizes powders into groups or cuts; sieving, the primary method for separating powders into their size fractions, serves as a diagnostic tool for quality assessment or a manufacturing technique for selecting specific size distributions.
Companies are facing evolving market demands, regulatory pressures, and competition from alternative energy sources. For Chevron, this means leveraging the company’s strengths to advance new products and solutions that improve reliability and lower the carbon intensity of their operations around the world. Modernization is a key component in tackling these challenges and driving competitive advantage. […]
Materials so thin they are considered two-dimensional are only a couple atoms thick and, at this scale, they behave in surprising ways. Graphene, for example, is ultrathin graphite, the same material used in pencils. But once sliced to a nanosized thickness, it becomes stronger than steel by weight and is among the best materials for […]
New research, conducted at the Department of Energy’s SLAC National Accelerator Laboratory, illuminates the strange behavior of gold when zapped with high-energy laser pulses. When certain materials, such as silicon, are subjected to intense laser excitation, they quickly fall apart. But gold does the opposite: It becomes tougher and more resilient. This is because the […]
