Electrified quantum diamond to become essential for quantum networks
Dmitry Fedyanin from the Moscow Institute of Physics and Technology and Mario Agio from the University of Siegen and LENS have predicted that artificial defects in the crystal lattice of diamond can be turned into ultrabright and extremely efficient electrically-driven quantum emitters.
Flexible electronics ‘flex’ their muscles
What’s inside all electronic devices? The answer is rigid components like circuit boards, containing chips, resistors and capacitors - all held together with wires. Nicolette Emmino explains that things could be about to change.
Extended battery life enhances gas detector
The PS200 portable gas detector from Tyco Gas & Flame Detection is now available with a new catalytic bead sensor option that provides an increased battery life of up to 80 hours in diffusion mode and 20 hours in pump mode.
Efficient hydrogen production through solar water splitting
Researchers from Delft University of Technology (TU Delft, The Netherlands), in collaboration with colleagues from the École Polytechnique Fédéral de Lausanne (EPFL, Switzerland), have found a simple yet very effective solution to greatly increase the efficiency and stability of hydrogen production through solar-driven water splitting. By separating the positive and the negative electrodes using a bipolar membrane, they were ...
Making nail polish while powering fuel cells
Hydrogen is widely regarded as a promising and clean alternative energy source. The traditional source of H2 for fuel cell use is water, which is split into H2 and O2. But O2 is a low-value product. So, this week in ACS Central Science, researchers report a new approach and a new catalyst that can produce not just hydrogen but also valuable chemicals, including the most common ingredient in nail polish.
EDLCs offer long life for backup power supplies
Combining low resistance with guaranteed long life over a wide temperature range (from -40 to +65°C), Panasonic Automotive & Industrial Systems Europe announces its HL series EDLCs (Electric Double Layer Capacitors). The gold capacitors are wound radial lead type devices, which achieve far better (up to 1,000 times greater) capacitance compared to aluminium electrolytic capacitors, as well as superior charge and discharge performance comp...
Electronic skin patch monitors alcohol levels
Engineers at the University of California San Diego have developed a flexible wearable sensor that can accurately measure a person's blood alcohol level from sweat and transmit the data wirelessly to a laptop, smartphone or other mobile device. The device can be worn on the skin and could be used by doctors and police officers for continuous, non-invasive and real-time monitoring of blood alcohol content.
Swapping substrates improves edges of graphene nanoribbons
It is now feasible to make a prized material for spintronic devices and semiconductors - monolayer graphene nanoribbons withzigzag edges.Miniscule ribbons of graphene are highly sought-after building blocks for semiconductor devices because of their predicted electronic properties. But making these nanostructures has remained a challenge. Now, a team of researchers from China and Japan have devised a method to make the structures in the lab. Thei...
Boron boosts graphene's sensitivity to noxious gases
Detecting noxious gases, such as those released from power plants and other sources that can harm the environment, is something graphene does well, but it could be even better. Researchers discovered a way to significantly improve its performance by peppering high-quality graphene sheets with boron impurities. Compared to pristine graphene, these modified sheets, a.k.a. boron-doped graphene, were 27 times more sensitive at detecting nitrogen diox...
