Would you rather run into a brick wall or into a mattress? For most people, the choice is not difficult. A brick wall is stiff and does not absorb shocks or vibrations well; a mattress is soft and is a good shock absorber. Sometimes, in designing materials, both of these properties are needed. Materials should be good at absorbing vibrations, but should be stiff enough to not collapse under pressure. A team of researchers from the UvA Institute of Physics has now found a way to design materials that manage to do both these things.

The race is on to engineer alternatives to traditional building materials that either perform better or tread more lightly on the planet. From super-strong plastics to fungus columns, we’ve rounded up 10 materials that could be the future of construction.

The first demonstration of a functional microchip integrating atomically thin two-dimensional materials with exotic properties heralds a new era of microelectronics. The world’s first fully integrated and functional microchip based on exotic two-dimensional materials has been fabricated at KAUST.

The material can self-heal in just 24 hours when warmed to 158°F or in about a week at room temperature.

Stanford professor Zhenan Bao and his team have invented a multi-layer self-healing synthetic electronic skin.

This is according to a report by Fox News published on Friday.

Scientists have developed an advanced technique for 3D printing that is set to revolutionize the manufacturing industry.

The group, led by Dr. Jose Marques-Hueso from the Institute of Sensors, Signals & Systems at Heriot-Watt University in Edinburgh, has created a new method of 3D printing that uses near-infrared (NIR) light to create complex structures containing multiple materials and colors.

They achieved this by modifying a well-established 3D printing process known as stereolithography to push the boundaries of multi-material integration. A conventional 3D printer would normally apply a blue or UV laser to a liquid resin that is then selectively solidified, layer by layer, to build a desired object. But a major drawback of this approach has been the limitations in intermixing materials.

A team from NIST and the University of Colorado Boulder have developed a novel device using gallium nitride nanopillars on silicon that significantly improves the conversion of heat into electricity. This could potentially recover large amounts of wasted heat energy, benefiting industries and power grids.

Researchers at the National Institute of Standards and Technology (NIST) have fabricated a novel device that could dramatically boost the conversion of heat into electricity. If perfected, the technology could help recoup some of the heat energy that is wasted in the U.S. at a rate of about $100 billion each year.

From ocean depths to mountain peaks, humans have littered the planet with tiny shards of plastic. We have even absorbed these microplastics into our bodies—with uncertain implications.

Images of plastic pollution have become familiar: a turtle suffocated by a shopping bag, water bottles washed up on beaches, or the monstrous “Great Pacific Garbage Patch” of floating detritus.

Researchers have synthesized a chalcogenide compound that has the electronic structure of an ideal Dirac semimetal—which could facilitate the study of this exotic class of materials.
