Formation and Characterization of Bisthiourea Zinc Formate

Croatica Chemica Acta, 2005
Ustanovljeno je da metodom topljivosti u sustavu Zn(HCOO)2-CS(NH2)2-H2O pri 25 °C nastaje novi kompleksnispoj. Određivanje sastava pokazalo je da se radi o Zn(HCOO)2 * 2CS(NH2)2. Pri 25 °C bistiourea cinkov format (BTZF) neprimjereno je topljiva sol. Spoj je opisan rentgenskom difrakcijom na prahu, IR spektroskopijom i termičkom analizom.

In Situ Pseudo‐Halide Diffusion Enables Buried Interface Regulation and Crystallinity Enhancement in Perovskite Solar Cells

Advanced Science, EarlyView.
Thermally activated LiHCOO induces in situ pseudo‐halide diffusion, promoting buried interface strain release and perovskite crystallization. The monoclinic LiHCOO phase forms an open framework structure that enhances HCOO− diffusion and drives interfacial restructuring.

Operando Raman Spectroscopy Reveals Backpressure‐Controlled Dynamics in Diluted CO2 Electrolysis

Advanced Science, EarlyView.
High backpressure operation governs the CO2 reduction reaction (eCO2RR) kinetics and selectivity, as well as the CO2 and water dynamics, as revealed through operando Raman spectroelectrochemical measurement. Operating eCO2RR near diffusion‐limited conditions provides a platform for investigating the competition between eCO2RR and the hydrogen evolution

Construction of Sabatier Volcanoes for CO2 Hydrogenation to C1‐2 Oxygenates Using Data‐Efficient Machine Learning

Advanced Science, EarlyView.
A new data‐efficient framework combining DFT calculations, a neural network model, and automated graph analysis of catalytic reaction networks is proposed and applied to CO2 hydrogenation on transition metal nanoparticles. The analysis shows how efficient C2 oxygenate production requires a balance between CHx formation, C–C coupling, protonation, and ...

Allosteric Inhibition of Polycomb Repressive Complex 2 by an EZH2‐Selective Small Molecule Inhibitor

Advanced Science, EarlyView.
The study characterizes C36, a highly selective EZH2/PRC2 inhibitor that acts via a novel allosteric mechanism. Unlike previous inhibitors, C36 inhibits EZH2/PRC2 by disrupting the allosteric communication between EZH2 and EED in a SAM‐noncompetitive manner.

Adaptive Coordination Engineering for Efficient and Robust H2 Release

Advanced Science, EarlyView.
β‐H elimination is a pivotal but challenging step in homogeneous formic acid dehydrogenation reactions due to strict hydride‐metal matching. By using a rationally designed Pd1Ag2 bimetallic system with adaptive Pd1‐Ag2/L2 coordination and formate bridges, it enables boosted formic acid dehydrogenation under ambient air (7.7 times higher than a Pd ...
