More efficient conversion of heat into electricity by tinkering with nanostructure

Scientists have not only been able to explain how nanostructures in thermoelectric materials can improve energy efficiency but they also propose a commercially more attractive way to manufacture nanostructured thermoelectric materials, increasing the chances for mass-production of thermoelectric energy.

It's what on the inside that counts

Sometimes, the inside of a material can determine what happens on the outside. A team of physicists has devised a new way to make use of this general truth, in particular in systems that do not conserve energy.

Novel glass materials made from MOFs and inorganic components

Researchers succeeded in creating a new class of hybrid glass materials that combine organic and inorganic components. To do this, the scientists use special material combinations in which chemical bonds between organometallic and inorganic glasses can be generated.
