Hybrid organic-inorganic halide perovskites (HPs) show great potential for optoelectronic applications. However, their poor stability against moisture and oxygen significantly limits practical Developing hybrid with improved is essential yet remains a considerable challenge. Lead-free A3Bi2I9 have become attractive semiconductor materials next-generation X-ray sensing because of elevated bulk resistivity, efficient absorption, low ion migration. Nonetheless, the increased spacing between...
A methyl parathion electrochemical sensor based on nano-TiO2 and graphene composite film modified glassy carbon electrode has been developed. The behavior of MP at the was investigated by cyclic voltammetry linear sweep voltammetry. Scanning electron microscopy used to characterize surface morphology film. Compared with a bare or mono-film electrode, redox peak currents improved greatly, indicating that showed good catalytic effects. optimal experimental condition obtained. results indicated...
A palladium-catalyzed N-acylation of tertiary amines by carboxylic acids was achieved through C-N cleavage. This reaction showed a wide substrate scope. Both aromatic and aliphatic served well as the acylating reagents coupled with to produce corresponding amides in good excellent yields. With strategy, bioactive were also efficiently modified, highlighting synthetic value process organic synthesis.
A useful versatile samarium–CuI based carbonyl addition protocol <italic>via</italic> organohalides was achieved, with the advantages of excellent efficiency, broad applicability and high chemoselectivity.
Aiming to address the serious problem of coal wall spalling in triangular zone face end under high-intensity mining, this paper introduces inorganic cement grouting reinforcement technology for medium-depth holes based on specific geological conditions Sihe mine China. Firstly, effects different water-to-material ratios and various accelerators setting time uniaxial compressive strength (UCS) materials consolidation are studied. The results show that combination 2% accelerator I, 0.3% II,...
The structures and energies of a Ga4N4 cluster have been calculated using full-potential linear-muffin-tin-orbital molecular-dynamics (FP-LMTO MD) method. We obtained twenty-four for cluster. most stable structure we is Cs three-dimensional structure, the energy which lower than that C2v symmetry proposed by Kandalam et al. [J. Phys. Chem. B 106 (2002) 1945] results show isomer with an N3 subunit preferred, supporting previous result made found clusters presented semiconductor-like...
A novel three-component reaction was developed via a one-pot strategy for the construction of diarylmethanol esters by using halobenzene and an ester in N,N-dimethylformamide (DMF) under mild conditions. The involves direct functionalization Sm–CuI catalyst system. It proved that 10% (mol) CuI is sufficient to realize reductive coupling reaction. Influences substituents were illustrated from both electronic steric effects. mechanism also discussed.
The structures of Ga3N, GaN3, Ga3N2 and Ga2N3 clusters are studied using the full-potential linear-muffin-tin-orbital molecular dynamics (FP-LMTO MD) method. Four for five nine have been obtained. most stable these planar ones. A strong dominance N–N bond over Ga–N Ga–Ga bonds appears to control structural skeletons, supporting previous result obtained by Kandalam co-workers. small GaN displayed semiconductor-like properties through calculation HOMO–LUMO gaps.
