Synthetic Control of Water‐Stable Hybrid Perovskitoid Semiconductors

Advanced Materials, EarlyView.
Hybrid metal‐halide perovskites are promising semiconductors for optoelectronics, yet their water stability is problematic. A new synthesis method is developed using lead iodide and cysteamine under various pH conditions, forming stable perovskitoid structures.

Expression and Characterization of Relaxin Family Peptide Receptor 1 Variants

Frontiers in Pharmacology, 2022
G-protein coupled receptors (GPCR) transduce extracellular stimuli into the cell interior and are thus centrally involved in almost all physiological-neuronal processes.

Domain Movements upon Activation of Phenylalanine Hydroxylase Characterized by Crystallography and Chromatography-Coupled Small-Angle X-ray Scattering.

Journal of the American Chemical Society, 2016
Mammalian phenylalanine hydroxylase (PheH) is an allosteric enzyme that catalyzes the first step in the catabolism of the amino acid phenylalanine. Following allosteric activation by high phenylalanine levels, the enzyme catalyzes the pterin-dependent ...

Computational Potential Energy Minimization Studies on the Prion AGAAAAGA Amyloid Fibril Molecular Structures [PDF]

Published in [Recent Advances in Crystallography, ISBN: 978-953-51-0754-5, Editor Jason B. Bendict, InTech Open Access Publisher, 19 Sept 2012, hardcover] Chapter 12, DOI: 10.5772/47733, pp.297-312, 2012
X-ray crystallography, NMR (Nuclear Magnetic Resonance) spectroscopy, and dual polarization interferometry, etc are indeed very powerful tools to determine the 3D structures of proteins (including the membrane proteins), though they are time-consuming and costly.
