Mono- and sub-monolayer films of a high <i>T</i>1/2 spin-crossover molecule on HOPG: temperature- and light-driven spin-state transition Open
We investigated the properties of the spin-crossover complex deposited on highly oriented pyrolytic graphite (HOPG) by x-ray absorption spectroscopy in the temperature range from 10 to 350 for sample thicknesses fro…

Femtosecond spin-state switching dynamics of spin-crossover molecules condensed in thin films Open
The photoinduced switching of Fe(II)-based spin-crossover complexes from singlet to quintet takes place at ultrafast time scales. This a priori spin-forbidden transition triggered numerous time-resolved experiments of solvated samples to e…

Defying the inverse energy gap law: a vacuum-evaporable Fe(<span>ii</span>) low-spin complex with a long-lived LIESST state Open
The novel vacuum-evaporable complex [Fe(pypypyr) 2 ] is in its LS state up to at least 510 K. Still, its light-induced HS state has a half time of several hours at 10 K, which is caused by a large structural difference between the two spin…

Thermo-Catalytic Reforming (TCR)–An important link between waste management and renewable fuels as part of the energy transition Open
The significant progress in energy demands and limited fossil fuel sources, together with environmental concerns, have enforced the study of green, renewable, and sustainable energy sources. Biomass and its residues can be converted into v…

Spin Crossover in a Cobalt Complex on Ag(111) Open
The Co‐based complex [Co(H 2 B(pz)(pypz)) 2 ] (py=pyridine, pz=pyrazole) deposited on Ag(111) was investigated with scanning tunneling microscopy at ≈5 K. Due to a bis(tridentate) coordination sphere the molecules aggregate mainly into tet…

Biochar—just a black matter is not enough Open
What differs biochar from charcoal? The simple answer is that biochar is a carbon-rich product obtained from the thermal decomposition of organic material, at the presence of no or only a bit of oxygen. In principle, the production of bioc…

Facile and Robust Solvothermal Synthesis of Nanocrystalline CuInS2 Thin Films Open
This work demonstrates that the solvothermal synthesis of nanocrystalline CuInS2 thin films using the amino acid l-cysteine as sulfur source is facile and robust against variation of reaction time and temperature. Synthesis was carried out…
