By using a technology that is normally suited to cleaning jewelery, with common solvents, ultrasounds, and 1 milligram of layered material (such as graphite), Dr. Valeria Nicolosi, the collaborator from the University of Oxford says they can make "billions and billions of one-atom-thick nanosheets can be made at the same time from a wide variety of exotic layered materials."
A team of Ukranian and American scientists have discovered that by using structures called ferroelectric nanowires, they can generate electricity from a temperature difference. This concept is now new, but rather uses different approaches and materials. It can harvest energy by using the temperature difference between materials and/or ambients.
A team of scientists from important US research institutes such as the Brookhaven National Laboratory, Columbia University, Argonne National Laboratory, Los Alamos National Laboratory, Northwestern University and the Swiss Federal Institute of Technology, while studying lead chalcogenides (lead paired with tellurium, selenium or sulfur), have discovered how these behave at an atomic scale and how they could offer great thermoelectric properties.
