Solid-state NMR on complex biomolecules: Methods and applications [PDF]

, 2018
Solid-state NMR (ssNMR) can provide structural information at the most detailed level and, at the same time, is applicable in highly heterogeneous and complex molecular environments, largely irrespective of solubility or crystallinity.

Self‐Assembled Crystalline Peptoid Nanomaterials as Metal‐Free Enzyme Mimics for Enhanced Carbon Dioxide Hydration and Precipitation

Advanced Functional Materials, EarlyView.
Inspired by metal‐free carbonic anhydrases (CAs) that achieve efficient catalysis without metal cofactors, we herein report a sequence‐defined supramolecular peptoid platform that mimics metal‐free CAs and exhibits hydrolytic activity via a supramolecular assembly‐mediated proton‐transfer mechanism.

Stereometric Molecular Engineering for Ultra‐Stable Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
Stereochemical configuration of molecular additives greatly influences interfacial adsorption at the Zn surface. The optimal tilted dual‐anchored adsorption geometry of myo‐inositol constructs a water‐deficient interface and regulates the solvation structure.

Charge‐Polarized Ni─S4 Single‐Atom Sites Drive Selective Photoreforming of Poly(lactic acid) to Lactate and Hydrogen

Advanced Functional Materials, EarlyView.
Atomically dispersed Ni–S4 sites on CdS nanorods induce interfacial charge polarization, directing photogenerated electrons to H2 evolution and holes to selective ester‐bond cleavage of poly(lactic acid). Without sacrificial reagents, this charge‐coupled system produces lactate while suppressing overoxidation, achieving an H2 evolution rate of 41.74 ...

Solution conformation of peptide PTSP in DMSO-d6 analyzed by 2D NMR(抑前胸腺肽溶液构象的2D NMR初步分析)

Zhejiang Daxue xuebao. Lixue ban, 2005
抑前胸腺肽PTSP是一种重要的新发现的昆虫神经肽，能够在体内和体外条件下抑制促前胸腺素PTTH对蜕皮激素合成的促进作用，实验材料PTSP以固相方法合成.用2D NMR技术来考察PTSP的DMSO-d6溶液，并记录COSY，NOESY和13C HMQC-COSY谱用于构象分析.利用2D COSY和NOESY归属了1H NMR谱的全部共振峰；再利用HMQC-COSY使全部αC和βC共振峰也得到了归属.分析得到肽链的1H和13C的化学位移和质子间的NOE，结果表明PTSP在DMSO ...
