The current socio-environmental and health problems that have arisen from the research of the presence of microplastics in the human body expose the need not only to reduce the use of plastics but to eliminate those that are already there. This proje

Actualment, més de la meitat de l'energia primària dels combustibles fòssils es perd a tot el món com a calor residual. Reciclar eficaçment aquesta calor residual és útil per superar la crisi energètica mundial. Els dispositius termoelèctric

Radiative thermal diodes based on two-element structures rectify heat flows thanks to a temperature dependence of material optical properties. The heat transport asymmetry through these systems, however, remains weak without a significant change in m

An organic free radical is a molecule with one or more unpaired electrons. Although most free radicals are highly reactive, chemists have developed a few families of so-called persistent organic radicals with high kinetic stabilities. Polychlorinated
