The title compound, C(10)H(12)ClNO(3), crystallizes with four independent mol-ecules in the asymmetric unit which are linked by inter-molecular N-H⋯O hydrogen bonds.

CHNHPbI perovskite nanofibers were synthesized by versatile electrospinning techniques. The synthetic CHNHPbI nanofibers were characterized by X-ray diffraction, scanning electron microscopy, thermogravimetric analysis, and photoluminescence. As counter electrodes, the synthesized nanofibers increased the performance of the dye-sensitized solar cells from 1.58 to 2.09%. This improvement was attributed to the enhanced smoothness and efficiency of the electron transport path. Thus, CHNHPbI perovskites nanofibers are potential alternative to platinum counter electrodes in dye-sensitized solar cells.

The abnormal self-assembly of the amyloid-&beta; peptide into toxic &beta;-rich aggregates can cause Alzheimer&rsquo;s disease. Recently, it has been shown that small gold nanoparticles (AuNPs) inhibit A&beta; aggregation and fibrillation by slowing down the nucleation process in experimental studies. However, the effects of AuNPs on A&beta; oligomeric structures are still unclear. In this study, we investigate the conformation of A&beta;(16-22) tetramers/octamers in the absence and presence of AuNPs using extensive all-atom molecular-dynamics simulations in explicit solvent. Our studies demonstrate that the addition of AuNPs into A&beta;(16-22) solution prevents &beta;-sheet formation, and the inhibition depends on the concentration of A&beta;(16-22) peptides. A detailed analysis of the A&beta;(16-22)/A&beta;(16-22)/water/AuNPs interactions reveals that AuNPs inhibit the &beta;-sheet formation resulting from the same physical forces: hydrophobic interactions. Overall, our computational study provides evidence that AuNPs are likely to inhibit A&beta;(16-22) and full-length A&beta; fibrillation. Thus, this work provides theoretical insights into the development of inorganic nanoparticles as drug candidates for treatment of AD.
