Ordered patterns of gold nanoparticles on a silicon base can be stimulated to produce collective electron waves known as plasmons that absorb only certain narrow bands of light, making them promising for a wide range of arrays and display technologies in medicine, industry, and science.

A team from NASA’s Goddard Space Flight Center in Greenbelt, Maryland, has been selected to develop a third-generation facility science instrument for the Stratospheric Observatory for Infrared Astronomy, SOFIA.The principal investigator, Samuel Harvey Moseley will lead the team to develop the High Resolution Mid-InfrarEdspectrometre(HIRMES).

Intuition suggests that a sample of material compressed uniformly from all sides should reduce its dimensions. Only a few materials subjected to hydrostatic compression exhibit the opposite behaviour, expanding slightly in one or two directions. Researchers at the Institute of Physical Chemistry of the Polish Academy of Sciences have developed a material with exceptionally high negative compressibility via a previously unknown mechanism.

With a 36% yield, the solar panels developed by startup Insolight could deliver up to twice as much energy as traditional panels. The company came up with a thin structure that directs the sun’s rays to the small surface area of very high performance solar cells. The result is a highly efficient flat photovoltaic system.

Doing a great job at keeping out water, greases or liquid, O-rings, gaskets and seals do sometimes however have such low vapour resistance that gasses, such as water vapour, can pass through them virtually unhindered (e.g cellulose, EVOH or PVOH). This dramatically reduces their effectiveness.

Using the giant ALMA telescope in Chile, astronomers in Japan, the UK, Sweden and Germany have found oxygen in an extremely distant galaxy – farther away than oxygen has ever been found before. The finding opens the door to methods of studying galaxies in the universe’s childhood and provides a key to unravelling this enigmatic epoch of the universe’s history when the gas between the galaxies shifted from being neutral to being ...

You may not think about insulation much, but it's one of those unsung industry heroes that keeps our drinks cold and homes warm on those bone-chilling winter days. Insulation also is a key component to protecting NASA's Space Launch System and its super-cold fuels for the journey to Mars.

Researchers at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have developed a tough new catalyst that carries out a solar-powered reaction 100 times faster than ever before, works better as time goes on and stands up to acid.

Researchers at Penn State and the Molecular Foundry at Lawrence Berkeley National Laboratory are pushing the limits of electron microscopy into the tens of picometre scale, a fraction of the size of a hydrogen atom.The ability to see at this subatomic level is crucial for designing new materials with unprecedented properties, such as materials that transition from metals to semiconductors or that exhibit superconductivity.

How do you know your water is clean and safe to drink? Whether you live in Flint, Michigan, or a half a world away in northwest India, many families don’t have a good answer to this question.People use countless methods to clean their water — from purchasing filters and purification products, to boiling water on a stovetop, to relying on their local governments to guarantee tap water safety.
