Thermodynamic limit for synthesis of metastable inorganic materials

Science Advances, 2018
Amorphous forms serve as thermodynamic upper bounds on the free energy scale for synthesis of metastable crystalline polymorphs. Realizing the growing number of possible or hypothesized metastable crystalline materials is extremely challenging.

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites

Advanced Functional Materials, EarlyView.
We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Properties of Lithium bis(oxatlato)borate (LiBOB) as a Lithium Salt and Cycle Performance in LiMn2O4 Half Cell

International Journal of Electrochemical Science, 2006
Crystalline LiBOB which we prepared in our lab was observed by SEM method. Impurities of product were examined by XRD experiment. The decomposition voltage under a deoxidized current was 1V vs.Li+/Li, and under a oxidized current the electrochemical ...

Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance

Bio‐Inspired Synthesis of Macroporous Single Crystal Particles as Scattering Agents

Advanced Functional Materials, EarlyView.
A general strategy is presented that delivers unique, single‐crystal microparticles that combine submicron macroporosity and uniform particle shapes. A bioinspired approach is used to occlude three distinct types of additives – polystyrene microspheres, polymer vesicles and amino acids – within calcite single crystals, and subsequent thermal annealing ...

Compressibility of eleven inorganic materials

Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1965
Volume compression measurements were made on eleven inorganic materials to a maximum pressure of 10,000 atm. Coefficients of the empirical equation -ΔV/V o =a(P -2000)+b(P-2000)2 were determined for the substances studied. Values of a in units of 10-6 atm-1 and b in units 10-10 atm-2 are as follows: Monel-a=0.62 b=0; Waspalloy-a=0.65, b=0; sapphire-a=0.

Water Adsorption‐Induced Color Sensor: Insight Into the Sensing Mechanism and Interfacial Engineering for Improved Responsiveness

Advanced Functional Materials, EarlyView.
We report a unique color‐sensing phenomenon of a TiO2/SbSI:Sb2S3 device utilizing X‐ray absorption. Based on the revealed penetration and adsorption of water onto TiO2, we successfully improved the color response speed and sensitivity by incorporating a hydrophilic polymer interlayer, thereby opening up opportunities for photodetection applications ...
