Scientists 'bend' elastic waves with new metamaterials that could have commercial applications
Sound waves passing through the air, objects that break a body of water and cause ripples, or shockwaves from earthquakes all are considered "elastic" waves. These waves travel at the surface or through a ...
Researchers find salmon semen can be used to extract rare earth elements from waste
Wearable tech for the battlefield and people at risk for heart attacks
Wearable devices can count the steps you take and the calories you burn. But can they help soldiers in the field? Or prevent someone from having a heart attack?
Startup scales up graphene production, develops biosensors and supercapacitors
An official of a materials technology and manufacturing startup based on a Purdue University innovation says his company is addressing the challenge of scaling graphene production for commercial applications.
LEDs made from 'wonder material' perovskite
(Phys.org) —Colourful LEDs made from a material known as perovskite could lead to LED displays which are both cheaper and easier to manufacture in future.
US college has system to extract water from manure
A technology for extracting drinkable water from manure is on its way to commercial application this year, a U.S. university said Thursday.
Making money from lignin: Roadmap shows how to improve lignocellulosic biofuel biorefining
When making cellulosic ethanol from plants, one problem is what to do with a woody agricultural waste product called lignin. The old adage in the pulp industry has been that one can make anything from lignin ...
Genetic engineering increases yield of biodegradable plastic from cyanobacteria
The production of plastics using biological systems such as bacteria could lead to the sustainable manufacture of biodegradable and biocompatible plastics using carbon from the atmosphere. So far, however, ...
Tiny camera records details of scene without losing sight of the big picture
To capture all the details of a crime scene, you might take many photos at close range. To get the whole scene at once, you could use a wide-angle or fisheye lens; but without an especially large lens you ...
Device that can manipulate radiofrequency signals could soon reduce size of short-distance communication systems
Millimeter waves are a type of radiofrequency electromagnetic radiation with wavelengths between 0.1 and 10 millimeters long. Because they are susceptible to absorption by water in the atmosphere, they travel ...
Mobile PCB cleanup system developed
University of Calgary scientists have developed new technology that promises a safer, cheaper way to clean up hazardous PCBs in soil using ultraviolet light – the first technology of its kind in the world.
Brown algae reveal antioxidant production secrets
Brown algae contain phlorotannins, aromatic (phenolic) compounds that are unique in the plant kingdom. As natural antioxidants, phlorotannins are of great interest for the treament and prevention of cancer ...
Size matters as nanocrystals go through phases
(Phys.org) —Understanding what happens to a material as it undergoes phase transformations – changes from a solid to a liquid to a gas or a plasma – is of fundamental scientific interest and critical ...
Jagged graphene edges can slice into cell membranes
(Phys.org) —A collaboration of biologists, engineers, and material scientists at Brown University has found that jagged edges of graphene can easily pierce cell membranes, allowing graphene to enter the ...
