Crystal structure of chlorido[1-(4-nitrophenyl)thiourea-κS]bis(triphenylphosphane-κP)silver(I)

Acta Crystallographica Section E: Crystallographic Communications, 2017
In the title compound, [AgCl(C7H7N3O2S)(C18H15P)2], the AgI ion is in a distorted tetrahedral coordination environment formed by P atoms from two triphenylphosphane ligands, one terminal S atom from the 1-(4-nitrophenyl)thiourea ligand and a chloride ion.

Imaging Hydrogen Bond in Real Space [PDF]

arXiv, 2013
Hydrogen bond is often assumed to be a purely electrostatic interaction between a electron-deficient hydrogen atom and a region of high electron density. Here, for the first time, we directly image hydrogen bond in real space by room-temperature scanning tunneling microscopy (STM) with the assistance of resonant tunneling effect in double barrier mode.

Two Distinct Modes of Hydrogen-Bonding Interaction in the Prototypic Hybrid Halide Perovskite, Tetragonal CH3NH3PbI3 [PDF]

arXiv, 2015
In spite of the key role of hydrogen bonding in the structural stabilization of the prototypic hybrid halide perovskite, CH3NH3PbI3 (MAPbI3), little progress has been made in our in-depth understanding of the hydrogen-bonding interaction between the MA+-ion and the iodide ions in the PbI6-octahedron network.

Non-adiabatic theory of the hydrogen bond. Quantum computation? [PDF]

arXiv, 2021
The hydrogen bond is usually described within the clamped nucleus approximation in which electronic and vibrational motions are considered separately. This approach leads to a double-well potential which facilitates proton tunnelling. In this work, the hydrogen bond is described by a formalism based on the non-adiabatic Hamiltonian in which electronic ...

Impacts of Device Geometry and Layout on Temperature Profile during Large‐Area Photonic Curing

Advanced Engineering Materials, EarlyView.
The study investigates how gate geometry affects peak curing temperature during photonic curing of solution‐processed indium zinc oxide thin‐film transistors. Using 3D simulations and experimental validation, it reveals that larger gate areas and smaller aspect ratios increase curing temperature and thus improve transistor performance. Findings provide
