Quantum tunneling pushes the limits of self-powered sensors
The proposed device, with a theoretical operating energy budget less than 10 attojoules, uses a differential architecture to compensate for environmental variations and the device can retain sensed information for durations ranging from hours to days.
Mastering the art of nanoscale construction to breathe easy and bust fraud
A new way to arrange very small materials with perfect control could lead to more secure banknotes and passports, and quicker detection of harmful gas through a clever use of light.
Metal-organic frameworks become flexible
Researchers have used experiments and simulations to find out by what means MOFs can be rendered flexible and why: they tricked the system by using clever chemical manipulations to enable a variety of energetically similar arrangements in the crystalline order.
