Bioengineers are trialling how to use shrimp shells to make biopolymer nanocomposite materials for biodegradable shopping bags, as a 'green' alternative to oil-based plastic, and as a new food packaging material to extend product shelf life.
Researchers have demonstrated the high-performance potential of an experimental transistor made of a semiconductor called beta gallium oxide, which could bring new ultra-efficient switches for applications such as the power grid, military ships and aircraft.
When carbon nanotubes and 3D printing combine with the right polymer, in this case a thermoplastic, something special occurs: electrical conductivity increases and makes it possible to monitor liquids in real time.
A new material, called 'rewritable magnetic charge ice', has an unprecedented degree of control over local magnetic fields. The artificial, magnetically charged structure is formed by manipulating local magnetic charges that set the state of the magnetic 'bits'.
Researchers have advanced gallium nitride (GaN)-on-silicon transistor technology by optimizing the composition of the semiconductor layers that make up the device. The team created the high electron mobility transistor (HEMT) structure on a 200 mm silicon substrate with a process that will scale to larger industry-standard wafer sizes.
