A team of researchers from UMass Amherst have developed a method of constructing self-folding reversible origami structures on small length scales using Ultraviolet photolithographic patterning on photo-crosslinkable polymers.
A new discovery explains the difficulty in making blue light-emitting diodes (LEDs). They used advanced computer simulations to reveal the properties of gallium nitride, which is the main component of blue LEDs.
A research team led by Northwestern University has solved the solubility mystery of graphene oxide (GO) films using basic inorganic chemistry.
Researchers at the Application Center for Wood Fiber Research HOFZET of the Fraunhofer Institute for Wood Research, the Wilhelm-Klauditz-Institut WKI in Braunschweig have discovered a new research approach that has enabled the creation of lightweight and cost-efficient vehicle body for automobiles.
A group of scientists led by researchers at the Université de Versailles' Institut Lavoisier in France has worked out how to stably gift-wrap a chemical gas known as nitric oxide within metal-organic frameworks. Such an encapsulated chemical may allow doctors to administer nitric oxide in a more highly controlled way to patients, suggesting new approaches for treating dangerous infections and heart conditions with the biologically-active substance.
In a world-first achievement published in Nature, scientists from the RIKEN Center for Emergent Matter Science in Japan, along with colleagues from the National Institute of Material Science and the University of Tokyo, have developed a new hydrogel whose properties are dominated by electrostatic repulsion, rather than attractive interactions.
An international team of scientists predicts that a phenomenon known in physics as Fano resonance can exist in materials that are used in electronic devices.
The elastodynamic equations for inhomogeneous media are crucial to the seismology, the NDT of composites, the elastic metamaterials, etc. Recently, Dr. XIANG Zhihai from the Applied Mechanics Laboratory, Department of Engineering Mechanics, Tsinghua University found out that the accurate elastodynamic equations for inhomogeneous media should incorporate the gradient of pre-stresses.
Mechanical property of granular materials in landslide is of great significance. A recent research demonstrates that the numerical triaxial apparatus based on discrete element method is able to simulate and reproduce the triaxial tests in laboratory, which is published in Science China: Physics Mechanics & Astronomy 2014 vol.57(12) by professor Jiachun Li from Institute of Mechanics, Chinese Academy of Sciences. The title is "Simulation of triaxial response of granular materials by modified DEM".
Researchers at EPFL have studied strange quantum events taking place in an innovative superconducting material, paving the way to understand high-temperature superconductivity better.
