Calcium sulfide can be prepared by the direct reaction of the elements, calcined in an inert atmosphere, at a 1:1.05 molecular ratio: Ca+S+heat→CaS This white material crystallizes in a cubic structurelike rock salt and the bonding is highly ionic. This is consistent with its description as...
The periodic interconnection structure induced by π-π conjugation between TBPO molecules facilitates the more robust and stable bonding between TBPO and perovskite. After passivation, the stability of the device has been significantly improved, and the maximum efficiency reaches 22%. After 250 h of ...

The Functional-Type Treating Agent (Polysulfide) This component of the treating composition comprises a bis(alkoxysilyl)polysulfide. Some general examples of bis(alkoxysilylalkyl)polysulfides which can be used include the bis(2-trialkoxysilylethyl)polysulfides in which the trialkoxy groups consist of...
of SO2may be attributed to its effect on the reduction of Fe2O3and its bonding with C–O, COOH, and C(O)–O–C. NO enhanced Hg0removal by HICCA primarily through the homogeneous reactions of Hg0with N2O and O. In addition, NO also interacted with HICCA and promoted the ...
Enrofloxacin (EFX) reacting with Ca(II) afforded a new complex, [Ca(EFX)2(H2O)4] (EFX-Ca), which was structurally characterized both in solid and solution chemistry. E. coli and S. typhi were tested to be the most sensitive strains for EFX-Ca. The LD50 v
It encompasses (a) substrate ring-opening with pyrrolidine/AgNO3, (b) trapping of the intermediate silver sulfide with a suitable halide, (c) replacement of the pyrrolidino moiety with the aryl of a Grignard reagent, (d) oxidation of sulfur, and (e) cyclization to the final thiopyran (5)...
