Noise-cancelling headphones have become a popular accessory for frequent flyers. By analyzing the background frequencies produced by an airplane in flight and generating an “anti-noise” sound wave that is perfectly out of phase, such headphones eliminate disturbing background sounds. Although the headphones can’t do anything about the cramped seating, they can make watching a film…
Computational Chemistry Supports Research on New Semiconductor Technologies
As new methods have become available for understanding and manipulating matter at its most fundamental levels, researchers working in the interdisciplinary field of materials science have been increasingly successful in synthesizing new kinds of materials. Often the goal of researchers in the field is to design materials that incorporate properties that can be useful for…
GCS Grants Hundreds of Millions of Computing Core Hours to National Science Projects
Computing time utilization has started for a new set of leading-edge, large-scale research projects on the Gauss Centre for Supercomputing’s (GCS) three Tier-0 high-performance computing (HPC) systems. GCS leadership approved 816.3 million core hours as part of the organization’s 20th Call for Large-Scale Projects—research projects that require a minimum of 35 million core hours of…
Supercomputing Simulations and Machine Learning Help Improve Power Plants
In conventional steam power plants, residual water must be separated from power-generating steam. This process limits efficiency, and in early generation power plants, could be volatile, leading to explosions. In the 1920s, Mark Benson realized that the risk could be reduced and power plants could be more efficient if water and steam could cohabitate. This…
Simulation and Experiment Help TU Dresden Researchers Study Next-generation Semiconductors
Semiconductors–a class of materials that can function as both electrical conductor and insulator, depending on the circumstances–are an essential technology for all modern electronic innovations. Silicon has long been the most famous semiconductor, but in recent years researchers have studied a wider range of materials, including molecules that can be tailored to serve specific electronic…
