Moving bodies can be attracted to each other, even when they’re quite far apart and separated by many other objects: That, in a nutshell, is the somewhat unexpected finding by a team of researchers at MIT.
In an effort to design novel materials for energy applications, scientists have developed a unique system to make artificial polymers that mimic the ubiquitous proteins, which are nature's own polymers and are involved in all aspects of life.
What happens if the symmetry of metamaterial is broken by the direction of illumination rather than by the material itself? Curiosity surrounding this question led a team of researchers from the University of Southampton to discover a new type of optical activity. The researchers have published their findings in Applied Physics Letters, from AIP Publishing.
Atomic charges in chemical solutions are like Switzerland—they strive for neutrality. The tendency to balance charges drives dynamics when charged atoms or molecules, called ions, are present in solutions. Recently, researchers at the Department of Energy’s Oak Ridge National Laboratory have found new ways to influence selectivity for specific positively charged ions (cations) with the addition of simple receptors, not for cations but rather for negatively charged ions (anions).
A team of engineers has developed and tested a type of steel with a record-breaking ability to withstand an impact without deforming permanently. The new steel alloy could be used in a wide range of applications, from drill bits, to body armor for soldiers, to meteor-resistant casings for satellites.
New study highlights the role of electron diffusivity when turning waste heat into electricity
A novel 3D-printing process called selective separation sintering (SSS), has been developed by an engineer from the University of Southern California (USC). The process has won the first prize in the NASA In-Situ Materials Challenge, due to its breakthrough application in the construction of physical structures in space.
A new material, consisting of a unique chemical structure, has been created by a group of researchers from the University of Southern California, the University of California, San Diego, and Caltech. The material has a unique combination of properties: high hardness and elasticity.
New research has identified how liquid-like materials can change into a solid-like state without the addition of extra particles or changes in volume.
A new explanation of how gypsum forms may change the way we process this important building material, as well as allow us to interpret past water availability on other planets such as Mars. The work is reported in Nature Communications.
