Accurate measurement of ^{13}C - ^{15}N distances with solid-state NMR
, 2006 Solid-state NMR technique for measureing distances between hetero-nuclei in static powder samples is described. It is based on a two-dimensional single-echo scheme enhanced with adiabatic cross-polarization. As an example, the results for intra-molecular

Advanced Functional Materials, EarlyView.This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Interplay between Co-3d and Ce-4f magnetism in CeCoAsO [PDF]
, 2010 We have investigated the ground state properties of polycrystalline CeCoAsO by means of magnetization, specific heat and solid state NMR. Susceptibility and specific-heat measurements suggest a ferromagnetic order at about, $T_\mathrm{C}$=75 K.

Solid‐state NMR Structure Determination [PDF]
IUBMB Life, 2003 AbstractBiological applications of solid‐state NMR (SS‐NMR) have been predominantly in the area of model membrane systems. Increasingly the focus has been membrane peptides and proteins. SS‐NMR is able to provide information about how the peptides or proteins interact with the lipids or other peptides/proteins in the membrane, their effect on the ...

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions
Advanced Functional Materials, EarlyView.DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries

Hydrogen-bonded liquid crystals with broad-range blue phases [PDF]
, 2019 We report a modular supramolecular approach for the investigation of chirality induction in hydrogen-bonded liquid crystals. An exceptionally broad blue phase with a temperature range of 25 °C was found, which enabled its structural investigation by ...

Advanced Functional Materials, EarlyView.This work demonstrates the successful integration of a phenanthroline‐based 2D COF with MnI catalytic sites into a catholyte‐free membrane‐electrode‐assembly cell for CO2 electroreduction. The crystalline COF actively suppresses Mn⁰–Mn⁰ dimerization, achieving a turnover frequency of 617 h⁻¹ at 2.8 V (full‐cell potential), and enabling stable operation.

A Theoretical and Experimental Study on the Lewis Acid−Base Adducts (P4E3)·(BX3) (E = S, Se; X = Br, I) and (P4Se3)·(NbCl5) [PDF]
, 2001 The Lewis acid−base adducts (P4E3)·(BX3) (E = S, Se; X = Br, I) and (P4Se3)·(NbCl5) have been prepared and characterized by Raman, IR, and solid-state 31P MAS NMR spectroscopy. Hybrid density functional calculations (B3LYP) have been carried out for both
