Lighter vehicles can travel farther on less energy, driving demand for lighter automotive components. High-performance aluminum alloys, such as alloy 7075, are among the lightest and strongest options, but they require energy-intensive production that raises costs and therefore limits their use.
In an article recently published in the journal Additive Manufacturing, researchers discussed the mechanical characteristics and microstructure of a laser-fabricated, crack-free Al-Cu-Mg-Y alloy.
Researchers discussed the utility of de-alloyed water- and air-sensitive nanoporous metals and metalloids for emerging energy applications in a new study.
A team of Spanish researchers have applied the 5S production methodology to provide a framework for metal welding processes, with the aim of improving process efficiency, weld quality, sustainability, and worker safety. They have published their findings in a new paper in the journal Sustainability.
Master Bond EP4G-80Med is a one part epoxy designed for use in the assembly of medical devices. This system is formulated with a non-metallic, graphite filler, which leads to good thermal and electrical conductivity. It possesses a thermal conductivity of 1.44-1.73 W/(m•K) and a volume resistivity of 50-100 ohm-cm.
Metals typically soften as they expand when exposed to heat, but a research team directed by a City University of Hong Kong (CityU) scholar and other scientists have discovered a one-of-a-kind super-elastic alloy that can preserve its stiffness even upon being heated to 1,000 K (726.85 °C) or above, with almost zero energy dissipation.
A new study posted to the preprint* server Research Square, in submission to Scientific Reports, has presented organic residue analysis of ten Bronze Age daggers from archaeological digs at Pragatto, Italy.
Mature landfill leachate is a complex and highly contaminated discharge with high levels of ammonia nitrogen, toxic components, and limited biodegradability. A new review paper presented in the Sustainability journal looks at the potential of current anammox-based processes in treating mature landfill leachate.
A team of researchers recently published a paper in the journal Materials that demonstrated the effects of heat treatment on the microstructure, mechanical properties, and residual stress of the Invar alloys.
In recent years, photocatalytic solar energy conversion has become the focus of several research projects due to its potential to help end human dependency on fossil fuels. Now, a paper published in Applied Nano Materials has explored the use of MgB4 nanosheets for this purpose.
