When a train approaches or an ambulance with its siren blaring nears us, we hear the sound with an increased frequency, gradually decreasing slightly. As it passes, the frequency changes abruptly to a lower one, then decreases ...
Double-sided microlens arrays (DSMLAs) play a crucial role in improving the performance of optical devices, supporting applications from advanced imaging systems to laser beam homogenization. However, traditional manufacturing ...
One day, wind turbines may float off the coasts of California and southern Oregon, providing clean, renewable energy to millions of homes. But before construction can start, researchers are studying how to minimize the potential ...
Organic light-emitting diodes (OLED) have emerged as a new generation of display technology. Organic crystalline materials possess superior thermal stability, chemical stability, and high carrier mobility, making them an ...
Along with warmer and wetter winters across the UK and Europe, our summers are getting hotter with more frequent periods of extreme hot weather. And as well as affecting agriculture, infrastructure and wildlife, hot weather ...
Two-dimensional materials such as graphene promise to form the basis of incredibly small and fast technologies, but this requires a detailed understanding of their electronic properties. New research demonstrates that fast ...
Alloying is a key process in creating new materials. By combining metals with desirable traits, scientists can produce alloys with suitable properties. For example, stainless steel, formed by combining iron with chromium, ...
An international team of researchers has discovered that the quantum particles responsible for the vibrations of materials—which influence their stability and various other properties—can be classified through topology.
Multicomponent ultra-high temperature ceramic (UHTC) has attracted much attention in research due to its superior high-temperature mechanical properties, lower thermal conductivity and enhanced oxidation resistance.
Glasses and gels are two different types of solid materials that are commonly used in a wide range of settings. Despite their markedly different compositions, these distinct materials share some similar properties, for instance, ...
