The bottom-up assembly of nanoparticles into diverse ordered solids is a challenge because it requires nanoparticles, which are often quasi-spherical, to have interaction anisotropy akin atoms and molecules. Typically, has been introduced by changing the shape inorganic nanoparticle core. Here, we present design, self-assembly, optical properties, total structural determination Ag29(BDT)12(TPP)4, an atomically precise tetravalent nanocluster (NC) (BDT, 1,3-benzenedithiol; TPP,...
Chemical bath deposition (CBD) of tin oxide (SnO2) thin films as an electron-transport layer (ETL) in a planar-heterojunction n–i–p organohalide lead perovskite and organic bulk-heterojunction (BHJ) solar cells is reported. The amorphous SnO2 (a-SnO2) are grown from nontoxic aqueous chloride at very low temperature (55 °C) do not require postannealing treatment to work effectively ETL or BHJ cells, lieu the commonly used materials titanium (TiO2) zinc (ZnO), respectively. Ultraviolet...
A lead-free and air-stable organohalide semiconductor exhibiting noteworthy optoelectronic properties is investigated. With improvements in thin film processing, this material expected to yield good solar cell efficiency.
Distinct photocatalytic performance was observed when Ta3N5 synthesized from commercially available Ta2O5 or prepared TaCl5 via the sol–gel route. With respect to O2 evolution with Ag+ as a sacrificial reagent, produced commercial exhibited higher activity than When photocatalysts were decorated Pt nanoparticles in similar manner, route hydrogen 10% aqueous methanol solution where no can be detected. Detailed surface and bulk characterizations conducted obtain fundamental insight into...
Presented herein is a detailed discussion of the properties lattice dynamic and optoelectronic tantalum(V) oxynitride (TaON) nitride (Ta3N5), from experimental theoretical standpoint. The active Raman infra red (IR) frequencies TaON Ta3N5 were measured using confocal Fourier Transform Infrared spectroscopies (FTIR) calculated linear response method within density functional perturbation theory (DFPT). study leads to an exhaustive description spectra, including symmetry vibrational modes....

Organic–inorganic lead‐based halide perovskite compounds currently yield thin film solar cells with a power conversion efficiency (PCE) of >23%. However, replacing the lead less‐toxic elements while maintaining high PCE remains challenge. For this reason, there has been significant effort to develop Pb‐free compounds, including methylammonium bismuth iodide (MA 3 Bi 2 I 9 ), but such systems severely underperform when compared prototypical Pb‐based (MAPbI ). latter, it is known that...
The dynamic properties of protein and lipid regions mitochondrial membranes during the permeability transition (PT) process were studied by following anisotropy changes hematoporphyrin (HP) 1,6-diphenyl-1,3,5-hexatriene (DPH), respectively. We show that opening PT pore is accompanied a remarkable increase membrane fluidity which specifically localized to sites, while domains are unaffected. increased not related collapse transmembrane potential follows PT, as demonstrated comparison between...
We report on a significant photocurrent generation from planar device obtained by coating bare n doped silicon substrate with random network of multiwall carbon nanotubes (MWCNTs).

These results suggest are able generate and plays fundamental role in our device. The former effect is...
Nanoparticles from lignin and melanin derivatives are suitable sustainable catalysts for the cycloaddition of carbon dioxide to epoxides.
Glycerol carbonate (GC) has emerged as an attractive synthetic target due to various promising technological applications. Among several viable strategies produce GC from CO2 and glycerol its derivatives, the cycloaddition of glycidol represents atom-economic efficient strategy that can proceed via a halide-free manifold through proton-shuttling mechanism.
