Purdue researchers have discovered a new two-dimensional material, derived from the rare element tellurium, to make transistors that carry a current better throughout a computer chip.

Without careful management, distributed energy resources have the potential to cause unreliable power delivery, or even outages, and lead utility companies to overcharge customers. A new index will help ISOs and utilities account for uncertainties introduced by both the electricity market and DERs so utility companies can balance the distribution grid and find the fairest customer rates.

Mobile phones and tablets through so-called audio tracking, can be used by means of ultrasound to unnoticeably track the behaviour of their users: for example, viewing certain videos or staying in specific rooms and places. In the project SoniControl, St. Pölten University of Applied Sciences has developed a method for how this undetected (and usually unwanted) spying can be exposed and blocked. The result is the world's first ultrasound-firewall, which is now available for free in the app store.

Molecular switch will facilitate the development of pioneering electro-optical devices.

Scientists in Japan have shown that an oxyfluoride is capable of visible light-driven photocatalysis. The finding opens new doors for designing materials for artificial photosynthesis and solar energy research.

MIT researchers have built an ingestible sensor equipped with genetically engineered bacteria that can diagnose bleeding in the stomach or other gastrointestinal problems.
