The two crystal structures of C17H17,N2O2Cl2PS （NP-8） and C17H19N2O2PS （NP-10-Ⅱ） have beendetermined by Patterson method. The crystals belong to monoclinic system with space group of P21/aand P21/n respectively. There are four molecules in the unit cell. Cell parameters: a = 26.622 （7）A, b = 7.711 （2） A., c = 9.461 （3） A, β = 94.90°（4） and a = 18.879（3） A, b = 10.199 （13） A, c = 8.948（3） A, β= 94.30°（3） for the two cells. After refinement by block diagonal matrix least squares me-thod, R factors are 0.046 for 2971 reflections of NP-8 and 0.076 for 1711 reflections of NP-10-Ⅱ. Referring to molecular structures of NP-8 and NP-10-Ⅱ spectra data have been satisfactorilycxplained. The characteristic features of the structures have been discussed.

Theranostic prodrugs are promising for cancer medicine;however,the inability to activate these systems exclusively at the desired tumor location compromises the specificity and efficacy of cancer treatment.Here,we developed a fluorescent theranostic nanoprodrug with synergistic hydrogen-sulfidespecific and near-infrared(NIR)-light-controllable activation for imaging-guided chemo-photothermal cancer therapy.This nanoprodrug system was fabricated by the inclusion of hydrogen sulfide(H2S)-activatable small molecule to the theranostic prodrug and a photothermal transducer in the interior of a NIR-light-responsive container.

A method is described for determining dimethylI sulfide （DMS） in seawater. DMS was first extractedfrom the seawater using organic reagent, then reverse-extracted by 5% HgCl2. In the laboratory DMS wasreleased by concentrated HCI and finally measured by GC-FPD. The limit of detection me O.05 ng ofS. Measurements of DMS along surface transects and on wtital profibe across the EaSt China Sca （Ers）continental sheif showed tha itS conodIations of S in the surface seawater ranged from 64-180 ng/L andthat itS vertical djstribuion was divided into 3 trpes. Model talculations of a stagnant film show a DMSflux of 10.6 umol/m2d the air-sea inteIha.

A set of 201 experimental data on solubility of sulfur in silicate melts was collectedfrom literature to formulate the changes of sulfur solubility as a function of bulk compo-sition of the melts and pressure, temperature, and the fugacity of oxygen and sulfur. Aregular solution model and a polynomial function have been put forward, from which sol-ubility of sulfur in natural silicate magmas can be estimated. Synthetic application of twomethods makes it possible to evaluate activity of FeS in a silicate melt, which will be po-tentially valuable for predicting immiscibility of sulfide liquid in magmatic processes.

Biological removal of sulfide, nitrate, and p-cresol at a loading rate of 340 gS/(m^3 · d), 340 gN/(m^3 · d) and600 gC/(m^3 · d), respectively, was achieved in an upflow anaerobic sludge blanket(UASB) reactor. The ratio of C/S could affect the elemental sulfur(S^0) accumulation, and the C/S ratio of 1.75:1 was optimal for S^0 accumulation. Strains Pseudomonas sp., Simplicispira sp., and Rhizobium sp. could likely yield heterotrophs. Strains Arcobacter sp.,Sulfurimonas sp., Sulfurovum sp., and Sulfurospirillum sp. are the autotrophics required for the proposed UASB system. At high loading rate, the autotrophic denitrification pathway declined faster than the heterotrophic pathway.

Ⅰ. INTRODUCTIONA problem needing urgent resolution in the world at present is the study of the polyacetylene (PA) conductive material which is stable in the air. We produce the polyacetylene-like sulfide (SLPA) which is stable in the air from polyvinyl chloride, and characterize its structure and property, and make studies on the influence of sulfidation on PA’s electronic property by means of the quantum method.

Garnets have found important applications in modern technologies including magnetorestriction,spintronics,lithium batteries,etc.The overwhelming majority of experimentally known garnets are oxides,while explorations(experimental or theoretical)for the rest of the chemical space have been limited in scope.A key issue is that the garnet structure has a large primitive unit cell,requiring a substantial amount of computational resources.To perform a comprehensive search of the complete chemical space for new garnets,we combine recent progress in graph neural networks with high-throughput calculations.We apply the machine learning model to identify the potentially(meta-)stable garnet systems before performing systematic density-functional calculations to validate the predictions.We discover more than 600 ternary garnets with distances to the convex hull below 100 meV⋅atom−1.This includes sulfide,nitride,and halide garnets.We analyze their electronic structure and discuss the connection between the value of the electronic band gap and charge balance.

The stability issue has been acknowledged as the bottleneck in the practical application of perovskite photovoltaics,while the stabilized interface between the perovskites and charge transport layers dominates their stability performance under different stresses.Here,we developed a high-performance sulfurized zinc-titanium mixed oxide(ZTO-S)electron transport layer(ETL)to fabricate large-area efficient and long-term 85℃/85%RH stable perovskite solar modules.The scalably prepared ZTO-S using the facile spray coating method demonstrates excellent electron mobility close to that of Zn O,in addition to promoting the uniform crystallization of perovskite film across the entire module via the interaction between surface S and Pb^(2+).Furthermore,this novel coordination stabilized the interface and reduced the interfacial non-radiative recombination defects within the devices,yielding an efficient and stable performance for the modules.High efficiency of 21.73%and 17.50%was achieved for blade-coated 36 cm^(2)and 100 cm^(2)perovskite solar modules,respectively.In addition,the encapsulated module(36 cm^(2))shows an attractive humidity and heat stability(85℃/85%RH)performance with a maintained 93.5%of the initial PCE over 1000 h.
