Organic–inorganic hybrid halides flourish due to their thermal stability, plasticity, and optical properties. However, performance optimization through reasonable regulation has always been a challenge. Diverse anions offer broad range of possibilities options for the development stimulus-responsive materials, thereby facilitating optimization. Here, we have successfully synthesized two organic–inorganic photoluminescent halides, (NNDP)2MnX4 (NNDP = N,N-dimethylpiperidinium chloride; X Cl,...

Abstract. Nucleophilic high molecular-weight organic compounds (HMWOCs) are sensitive to protons (H+) in Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) analysis. A comprehensive evaluation of the diurnal evolution nucleophilic HMWOCs was performed. aged significantly daily cycles, accompanied by functionality shifts, particularly oxygenated and reduced nitrogen (CHON CHN) as well organics. The intensities (HMW) increased during both daytime nighttime. produced more...

Abstract 2D semiconductors have demonstrated outstanding switching performance in resistive random‐access memory (RRAM). Despite the proposed (RS) mechanism involving penetration of electrode metal atoms, direct observation these van‐der‐Waals stacked remains absent. This study utilizes molybdenum disulfide (MoS 2 ) as material, employing gold and multilayer graphene electrodes. Through analysis characteristics RRAM devices, pivotal role grain boundaries atoms is identify achieving RS....

An unprecedented porous organic framework, BSF-11, was prepared by the self-assembly of closo-dodecaborate [B12H12]2– and cationic 2,6-diaminopurine-Cu(II) complexes via multiple proton-hydride dihydrogen bonds. Single crystal structure analysis indicated that BSF-11 displays a 1D channel with narrow bottleneck (2.79 Å) large cavity (7.12 Å). The intrinsic porosity preserved after thermal activation in vacuum; showed pore opening adsorption C2H2 C3H4 while excluding other light hydrocarbons...

Two-dimensional (2D) semiconductors like molybdenum disulfide (MoS2) exhibit superior performance at nanometer-scale thickness compared to silicon. Notably, multilayers are more resistant breakage during transfer and boast enhanced electrical properties over monolayers. In this study, we synthesized 4-in. multilayer MoS2 using a rapid thermal processing system through the ammonium tetrathiomolybdate precursor thermolysis. A 200 nm-scale space confinement on sample surface was used reduce...
