Protein amide hydrogen exchange (HDX) is a convoluted process, whose kinetics determined by both dynamics of the protein and intrinsic rate labile atoms fully exposed to solvent. Both processes are influenced variety extrinsic factors. A mathematical formalism initially developed rationalize individual now often used interpret global (e.g., as measured in HDX MS experiments). One particularly important advantage direct visualization various states observing distinct ion populations with...
The extent of internal hydrogen exchange (scrambling) within multiply charged solvent-free protein ions was investigated using a small model protein. site-specific backbone amide protection data were obtained ion fragmentation in the gas phase and compared with available NMR data. Only minimal scrambling detected when relatively high-energy collisional activation used to fragment intact ions, while low-energy resulted more significant but not random exchange. Increased conformational...
This study investigated the effects of organic amendments (straw return, fertilizer, biochar, and their combinations) on grain yield, quality, soil biochemical characteristics in black wheat. A two-year field experiment (2022–2024) was conducted with five treatments: F (conventional fertilization), FS (F + full straw return), FO 3 t/ha fertilizer), FB biochar), FSOB fertilizer biochar). achieved highest increasing by 17.3% over due to a higher spike number 1000-grain weight. Grain protein...
Direct mass spectrometric characterization of interactions between proteins and small hydrophobic ligands often poses a serious problem due to the complex instability in gas phase. We have developed method that probes efficacy ligand—protein indirectly by monitoring changes protein flexibility. The latter is assessed quantitatively using combination charge state distribution analysis amide hydrogen exchange under both native mildly denaturing conditions. was used evaluate binding model...
Metal–semiconductor–metal (MSM) ultraviolet (UV) photodetectors have been widely studied owing to their advantages such as ease of preparation, high responsivity, and low costs. However, due the overlap between light absorption layer electron channel, sensitivity UV needs be improved. In this study, direct generation zinc oxide nanowires (ZnO NWs) with short lengths by focused ion beam (FIB) exposure spin-coated acetate films was observed for first time. The bottoms ZnO NWs were in contact...
Electron-only magnetic reconnection, in which ions do not couple, has recently been observed the turbulent magnetosheath and magnetotail is associated with flux rope coalescence. This paper reproduces electron-only reconnection that plasma environments via 2.5D particle-in-cell simulations. By statistical analysis study of individual ion trajectories. We have discovered reason why cannot form an out flow turbulence. Due to weak magnetization effect turbulence, it difficult for enter...
On the basis of variable-temperature single-crystal X-ray diffraction, variable-temperature/frequency dielectric analysis, solid-state nuclear magnetic resonance spectroscopy, and molecular dynamics simulations, here we present a new model crystalline supramolecular rotor (i-PrNHMe
