Solar cells made of artificial crystalline structures called perovskites have shown great promise in recent years. Now Stanford University scientists have found that applying pressure can change the properties of these inexpensive materials and how they respond to light.
A team of international researchers has successfully measured precise binding energy of a 10ËBe hypernucleus made of four protons (ñ), five neutrons (n) and and a Lambda (Ë) particle, at Thomas Jefferson National Accelerator Facility (JLab), USA.
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.
Faculty members from Cornell University are the main contributors of a new $317 million public-private collaboration, aiming to speed up innovations in the field of “smart” fabrics that can be adapted for use in apparel, electronics, consumer products, transportation, and protective gear for first responders and soldiers.
Researchers at Birmingham University have used Markes’ BenchTOF-Select time-of-flight mass spectrometer in combination with two-dimensional gas chromatography (GC×GC) to improve the separation and identification of hydrocarbons in motor oil.
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.
The silver electrical contacts that carry electricity out of about 90 percent of the solar modules on the market are also one of their most expensive parts. Now scientists from two Department of Energy national laboratories have used X-rays to observe exactly how those contacts form during manufacturing.
The detector group at the Swiss Light Source at PSI has been one of the pioneers in the development of custom-made hybrid pixel array detectors (HPADs) for synchrotron applications. In a paper published recently [Jungmann-Smith et al. (2016). J. Synchrotron Rad. 23, 385-394; doi:10.1107/S1600577515023541], this group shows that it is now possible to develop HPADs with sufficient low noise to allow single-photon detection below 1 keV as well as to perform spectroscopic imaging. A commentary has also been written about the work [Graafsma (2016). J. Synchrotron Rad. 23, 383-384; doi:10.1107/S1600577516002721].
