Theoretical Investigation of C_60 IR Spectrum
, 1996 A semi-empirical model of the infrared (IR) spectrum of the C$_{60}$ molecule is proposed. The weak IR-active modes seen experimentally in a C$_{60}$ crystalline sample are argued to be combination modes caused by anharmonicity. The origin of these 2-mode excitations can be either mechanical (anharmonic interatomic forces) or electrical (nonlinear ...

Synthesis And Characterization Of New Metals Complexes Of [N-(acetyl amino) Thioxomethyl] Valine
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017 A new ligand [N-(acetyl amino) thioxomethyl] valine was prepared from the reaction of acetyl iso thiocyanate with valine. The ligand was characterized by FT-IR, UV- vis and 1HNMR spectrum, The complexes with some metal ions (M +2 =Co,Ni,Cu,Zn,Cd,Hg ...

Exceptional Electro‐Optic Coefficient Unlocked via Polarization Swaying in KNbO3 Thin Films
Advanced Functional Materials, EarlyView.We present the largest reported electro‐optic response in any material to date, guided by a new design principle that exploits ultralow coercive field polarization swaying enabled by low‐symmetry ferroelectric phases in monoclinic KNbO3 thin films for energy‐efficient classical and quantum photonic integrated circuits. ABSTRACT The electro‐optic effect

Advanced Functional Materials, EarlyView.An ultrathin nanocomposite MXene‐based multilayer effectively blocks hydrogen permeation by presenting a tortuous, layered structure. When the MXene is layered with reduced graphene oxide modified with a polycation, the resulting nanocomposite retains its hydrogen gas barrier properties at temperatures as high as 400°C (permeability of 7.13 ± 0.09 × 10−

Advanced Functional Materials, EarlyView.Neuromorphic plasticity in OECTs is governed by the post‐stimulus evolution of coupled ionic and electronic states. Semiconductor chemistry and morphology, electrolyte composition and interfaces, and device architecture regulate ion injection, transport, confinement, and release, shifting responses from rapidly relaxing STP to metastable memory and ...

Beyond Primary Nucleation: Molecular Basis of Peptide Crystal Secondary Nucleation at Soft Interface
Advanced Functional Materials, EarlyView.High spatiotemporal‐resolution atomic force microscopy directly resolved peptide secondary nucleation (SN) and growth characteristics and mechanisms on HOPG. The landscape of peptide nucleation sites, growth dynamics, molecular‐scale structures, phase transitions, and cross‐seeding processes were realized.

How the Porous Transport Layer Dictates Membrane Electrode Assembly Performance of IrO2 Catalysts
Advanced Functional Materials, EarlyView.The Schottky barrier formed at the catalyst | PTL interface critically governs both the initial performance and long‐term durability of the PEMWE, and its magnitude is dictated by the catalyst's work function. This limitation can be resolved by combining a rutile IrO2 core for efficient electron transfer with an amorphous IrOx shell for high surface ...
