Copper is one of the most widely used metals, but extracting and refining it into a useful form can be energy intensive and requires harsh chemical treatments. But now, researchers at the University of Houston have discovered bacteria that naturally co… Continue reading “Mining” bacteria turn toxic copper ions into useful metal
Aerogel’s are extremely light and porous materials with wide-ranging potential, and mechanical engineers at the National University of Singapore (NUS) are getting pretty good at making them out of all kinds of waste products. Previously, this has inclu… Continue reading Metal waste turned into versatile aerogels in eco-friendly way
Things don’t fall from the sky without a damn good reason. US lawyers Baum Hedlund, who specialize in litigation concerning transport accidents, lists human errors as the main reasons (53 percent) for aircraft crashes, followed by manufacturing defects… Continue reading Compact imaging system promises to reinvent monitoring of metal fatigue
Rare earth magnets form an important part of many of today’s electronic devices, ranging from wind turbine generators to MRI scanners. Despite their prevalence, only a tiny fraction of these magnets are recycled once they reach the end of their lives, … Continue reading Rare earth magnets from old computers to find use in electric Bentleys
Researchers at Brown University have developed a new way to make super-hard metals. The team made nanoparticle “building blocks” that could be fused together under moderate pressure, thanks to a chemical treatment.Continue ReadingCategory: Materials, S… Continue reading “Super-hard” metals forged in new nanoparticle manufacturing process
Bacteria may seem like pretty simple lifeforms, but their ingenuity keeps surprising scientists. The latest example is a species called Geobacter sulfurreducens, which has now been found to survive exposure to toxic cobalt by building a metal “suit” li… Continue reading Bacteria build “Iron Man” suits by soaking up toxic cobalt
Like many heavy metals, arsenic can contaminate soil and groundwater as a byproduct of mining operations, and this poses all kinds of threats to human health and the environment. A novel type of biosensor could help us negate the risks of this highly t… Continue reading Sensor built into plant tissue tracks arsenic levels in real time
Treating wastewater to cleanse it of contaminants like heavy metals is a complex task, and one that often involves a slow-going, scattergun approach. Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory have now produced a mat… Continue reading New material cleans copper from wastewater with unmatched efficiency
Hybrid manufacturing systems like DMG Mori’s Lasertec 65 DED hybrid are starting to pop up here and there with the ability both to add metal via laser deposition 3D printing, and to subtract it via more traditional milling processes, giving you somewha… Continue reading Meltio Engine transforms any CNC machine into a hybrid 3D print system
Engineers at Cornell University have developed a new technique for 3D printing metallic objects – and it involves blasting titanium particles at supersonic speeds. The resulting metals are very porous, which makes them particularly useful for biomedica… Continue reading New 3D printing technique fuses titanium particles at supersonic speeds
