In this work, nitrogen doped resorcinol–melamine–formaldehyde (RMF) resins were synthesized, pyrolyzed and physically activated with CO2. The influence of the activation time on the physicochemical properties and the water sorption behavior produ

The relation among structure, electric transport, and photovoltaic effect is investigated for a $\mathrm{pn}$ heterojunction with strong correlation interactions. A perovskite interface is chosen as a model system consisting of the $p$-doped strongly

The thermoelectric performance of Ta substituted (ZrHf)NiSn-based half-Heusler compounds is studied. Here, Ta is used on the Hf site for controlling the charge carrier concentration in contrast to the widely used Sb substitution on the Sn site. The i
