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.

Physicists at the University of Arkansas have led an international team of scientists in a study to characterise the magnetic and electronic structure in transition metal oxides.
Researchers from the University of Oregon (UO) have conducted a spectroscopy experiment by illuminating four laser light pulses on nanoparticle photocells. This new research, which has been published in the Nature Communications journal, has provided an insight into the mechanism of converting captured sunlight into electricity.
The lithium-ion batteries that mobilize our electronic devices need to be improved if they are to power electric vehicles or store electrical energy for the grid. Berkeley Lab researchers looking for a better understanding of liquid electrolyte may have found a pathway forward. A team led by Richard Saykally, a chemist with Berkeley Lab’s Chemical Sciences Division, David Prendergast, a theorist with Berkeley Lab’s Molecular Foundry, and Steven Harris, a chemist with the Lab’s Materials Sciences Division, found surprising results in the first X-ray absorption spectroscopy study of a model lithium electrolyte.
An engineering team from the Kansas State University has unveiled certain vital properties of graphene oxide, which can enhance flexible batteries made of sodium and lithium-ions.
