Fiber optic technology is the holy grail of high-speed, long-distance telecommunications. Still, with the continuing exponential growth of internet traffic, researchers are warning of a capacity crunch. In AVS Quantum Science, researchers show how quantum-enhanced receivers could play a critical role in addressing this challenge. The scientists developed a method to enhance receivers based on quantum physics properties to dramatically increase network performance while significantly reducing the error bit rate and energy consumption.
Matthew Staymates, fluid dynamicist at the National Institute of Standards and Technology, is studying different mask types to determine which are the most effective at reducing disease transmission. In Physics of Fluids, he describes exploring the basic flow dynamics of N95 masks with or without exhalation valves. To do this, he generates stunning video from his schlieren imaging, a method to visualize the fluid flow away from the surface of an object, and light scattering.
Hydrogen is becoming a crucial pillar in the clean energy movement, and developing safe and cost-effective storage and transportation methods for it is essential but complicated, because hydrogen can cause brittleness in several metals including ferritic steel. Recent advancements are starting to provide insight into the embrittlement process. A review of various methods in Applied Physics Reviews improves the understanding of the structure, property, and performance of ferritic steels subjected to mechanical loading in a hydrogen environment.
A new literature review from scientists at George Washington University and the National Institute of Standards and Technology suggests that nutrition and diet have a profound impact on the microbial composition of the gut.
