This paper aims to improve the hydrothermal stability and catalytic activity of metal–organic frameworks (MOFs), which are believed play an important role in practical applications MOFs catalysis. Our strategy is incorporate graphite oxide into a typical MOF, namely HKUST-1 (Cu3(BTC)2, BTC = 1,3,5-benzenetricarboxylic acid; HKUST Hong Kong University Science Technology), properties MOF successfully tailored by use this strategy. The obtained MOF/graphite composites show enhanced porosity...
Polarized-light detection in the deep ultraviolet solar-blind region is indispensable for optoelectronic applications. 2D hybrid perovskite ferroelectrics with inherent anisotropy and bulk photovoltaic effect (BPVE) have become a robust candidate this portfolio. We here report wide band-gap ferroelectric, (isobutylammonium)2 (methylamium)Pb2 Cl7 (1), which BPVE behaves as self-driving source polarized-light detection. It exhibits large dichroism ratio (≈15.7) superior BPVE-directed...
Ferro-pyro-phototronic (FPP) effect is a triple coupling of ferroelectricity, light-induced pyroelectricity, and photo-excitation, which holds bright promise for next-generation modern optoelectronic devices. However, except few oxides (e.g., BaTiO3 ), new FPP-active candidates remain extremely scarce due to the knowledge lacking on underlying role three components. By tailoring interlayered spacers, authors present series 2D cesium-based perovskite ferroelectrics, (A')2 CsPb2 Br7 (where...

Abstract 2D organometallic halide perovskites are recently emerging as a robust family of ferroelectrics, which their inherent spontaneous polarization ( P s ) endows fascinating quadratic nonlinear optical properties. However, up to date, few studies reported tune and control the second harmonic generation (SHG) effect in this ferroelectric branch. Herein, first improper multilayered hybrid perovskites, (IA) 2 (EA) Pb 3 Br 10 1 , where IA is isoamylammonium EA ethylammonium), exhibits high...
Two-dimensional (2D) hybrid perovskites with intrinsic attributes of structural and optical anisotropy are holding a bright promise for polarization-sensitive photodetection. However, studies on self-powered detection to quite weak polarized light remain scarce in this 2D family. By incorporating an aromatic spacer into the 3D cubic prototype, we have successfully assembled new perovskite polar motif, (FPEA)2(MA)Pb2I7 (FMPI, where FPEA is 4-fluorophenethylammonium MA methylammonium). Its...
Abstract The evolution of proteins that bind to small molecules and catalyze chemical transformations played a central role in the emergence life. While natural have finely tuned affinity for their primary ligands, they also often weak affinities other molecules. These interactions serve as starting points new specificities functions. Inspired by this concept, we determined ability simple de novo protein set diverse (< 300 Da) crystallographic fragment screening. We then used information...
By confining the secondary dimethylammonium (DMA) cation in a distorted perovskite cavity, we assembled new 2D Ruddlesden-Popper metal halide of (i-BA)2(DMA)Pb2Br7 (i-BA = n-isobutylammonium), which DMA templates its inorganic framework and quantum-well motif renders fascinating photoresponse. Crystal-based planar arrays exhibit effective photodetection behaviors, including notable detectivity (∼5.6 × 1012 Jones), high responsivity (∼1.25 A W-1) large switching ratio (∼1.5 103). These...
Abstract Two‐dimensional (2D) organic–inorganic hybrid perovskites, benefiting from their natural anisotropy of quantum‐well motifs and optical properties, have shown remarkable polarization‐dependent responses superior to the 3D counterparts. Here, for first time, multiwavelength polarization‐sensitive detectors were fabricated by using single crystals a guanidine‐based 2D perovskite, (BA) 2 (GA)Pb I 7 (where BA + is n ‐butylammonium GA guanidium). Its unique structure results in strong...

A disadvantage in the design of gerotor pump is a lack parts that can be adjusted to compensate for wear rotor set, and as consequence, it causes sharp reduction efficiency. In this paper, an attempt has been made reduce rate between rotors pump. To do this, floating genetic algorithm (FGA) used optimization technique minimizing proportional factor (WRPF). The result shows reduced considerably, e.g. approximately 8% throughout using FGA.
