 E-Mail Tsukuba, Japan - A team of researchers lead by the University of Tsukuba have created a new theoretical model to understand the spread of vibrations through disordered materials, such as glass. They found that as the degree of disorder increased, sound waves traveled less and less like ballistic particles, and instead began diffusing incoherently. This work may lead to new heat- and shatter-resistant glass for smartphones and tablets. Understanding the possible vibrational modes in a ...

A breakthrough that has implications for molecular biology, pharmacology and nanotechnologies. The fields of application are many. Identifying the mechanisms behind neurodegenerative processes in some proteins, for example, can help limit their proliferation. Understanding how a protein takes on a certain shape can open the way to use the nanomachines that nature has designed to cut, edit or block damaged or defective genes. Their study was published in the international academic journal Physica...

 E-Mail Irvine, Calif., Jan. 11, 2021 - Often admired for their flawless appearance to the naked eye, crystals can have defects at the nanometer scale, and these imperfections may affect the thermal and heat transport properties of crystalline materials used in a variety of high-technology devices. Employing newly developed electron microscopy techniques, researchers at the University of California, Irvine and other institutions have, for the first time, measured the spectra of phonons - quant...

 E-Mail Atomic nuclei are held together by the strong interaction between neutrons and protons. About ten percent of all known nuclei are stable. Starting from these stable isotopes, nuclei become increasingly unstable as neutrons are added or removed, until neutrons can no longer bind to the nucleus and "drip" out. This limit of existence, the so-called neutron "dripline", has so far been discovered experimentally only for light elements up to neon. Understanding the neutron dripline and the ...

0.3Zr 2, has a superconducting transition at 8K, a relatively high temperature for an HEA. The teams approach may be applied to discovering new superconducting materials with specific desirable properties. Its been over a hundred years since the discovery of superconductivity, where certain materials were found to suddenly show minimal resistance to electrical currents below a transition temperature. As we explore ways to eliminate power waste, a way to dramatically reduce losses in power tran...

Were seeing as what you would expect to see after a tsunami there is debris littering the ground there are question cars crushed motorcycles or see buildings that are collapsed or partially collapsed walls that a fall down on each other officials of the tsunami was caused by an undersea landslide set off by the volcano Indonesian scientists are trying to establish whether it could pose further danger. The head of the United Nations team of observers is due to arrive in the Red Sea port of her d...
