Watch as this lightweight foam material stops balls as effectively as steel

Scientists have demonstrated a light foam of hollow metal balls that can withstand the incredible impact of .50 caliber bullets: the kind of bullets fired by heavy machine guns and sniper rifles. Weighing only about half of conventional steel armor, this material, referred to as composite metal foam (CMF), is equally effective at protecting these deadly projectiles, even when tested …

The old user interface is back] Google is launching a new interface for the Material Play Store with a lower navigation bar

Last month, we announced that the Play Store was about to be redesigned, including a new navigation bar at the bottom of the screen. Although this could only be activated by messing around with feature flags when we posted our first post, Google's new interface is now being extensively made available to users. As expected, the new theme elements have …

Google Material Theme redesign of the Play Store rollout

Back in April, we made a massive redesign of the Play Store possible, introducing Google Material Design. The latest version of Google Play officially introduces this revision to Android. As with other revisions, the material design of the Google Play Store theme also sets the main accents in the colors green (apps & games), red (movies & tv) or blue …

Laser technology could allow the use of tough material for next-generation electronics

Graphene, a super tough wonder material, has not yet made it into electronics because it does not conduct any electrical current itself. The researchers used a laser technique to permanently clamp graphene into a structure that allows the flow of electrical current. Credit: Purdue University / Gary Cheng In 2004, the researchers discovered a super-thin material that is at least …

A radiant cooling structural material

A stronger, cooler wood A good way to reduce the cooling requirements of a building is to ensure that infrared radiation is reflected. Passive radiant cooling materials are designed to do this very well. Li et al. Wood is processed by delignification and re-pressing into a mechanically strong material that also cools passively. They have modeled the cooling savings of …

Experiment produces new material that can conduct electricity perfectly – ScienceDaily

University of Chicago scientists are part of an international research team that has discovered superconductivity – the ability to conduct electricity perfectly – at the highest temperatures ever measured. The team studied a class of materials in superconductivity at temperatures of about minus 23 degrees Celsius (minus 9 degrees Fahrenheit) was observed – a jump of about 50 degrees compared …

New plastic material can always be recycled

As Berkeley Lab explains, the fillers and chemicals used in plastic objects are usually tightly bound to monomers – molecules that combine to form large plastic molecules, called polymers. These additives could lead to unexpected properties when blending various plastics for recycling. This means that items that have already been made from recycled plastics may need to go directly to …
