The spectra of nitrogen in nitrites and nitrates exhibit a structure of resonance levels in the low-energy part of the conduction band. Nitrogen K-edge absorption coefficients for the NKα radiation and the braking background are determined. Polarization spin density of nitrogen...
Electron spin resonance studies of semiquinones and related nitrogen heterocyclic molecules in acid solution Electron spin resonance (E.S.R.) spectra have been obtained from several semiquinones in strongly acidic media, where they exist as doubly protonated species. Hyperfine splitting was observed ...
Fig. 3: Influence of pyrene labeling of C374 on subunit interactions in actin filaments. Ribbon diagrams have stick figures of important side chains and balls for important backbone nitrogen atoms (blue), oxygen atoms (red), and Cα atoms (green or salmon). Gray arrows on the right column...
The selective transformation of nitrogen compounds is a foundation of the modern chemical industry. Existing thermochemical processes largely rely on fossil fuels and innovating electrocatalytic processes that could use renewable energy remains challengi
Here, we introduce a CoOx layer to tune the local electronic structure of Au nanoparticles with positive valence sites for boosting conversion of N2 to NH3. The catalysts, possessing high average oxidation states (~40%), achieve a high NH3 yield rate of ~15.1 μg·cmhand a good faradic ...
We report application of electron spin−echo envelope modulation (ESEEM) spectroscopy to the problem of metal coordination environments in structured RNA molecules. ESEEM has been used in conjunction with 15N-guanosine labeling to identify nitrogen ligation to a Mn2+ site in a hammerhead ribozyme and...
structure of nano-sized objects can be analysed with a resolution of 0.07 nm, the highest resolution capable with microscopic techniques [59]. The superior resolution ofTEMcompared to SEM stems from the higher accelerating voltage (100 keV), which provides an electron beam with smaller ...
The effect of nitrogen (N) doping on the behavior of field emission, surface energy and the band structure of strontium titanate(SrTiO3)thin films coated on silicon tip arrays has been examined in detail. Measurements using x-ray photoelectron spectroscopy, ellipsometry, water contact angle and fi...
Electronic Structure Trends in N-Heterocyclic Carbenes (NHCs) with Varying Number of Nitrogen Atoms and NHC Transition Metal Bond Properties Carbenes derived from five-membered heterocycles with different numbers of nitrogen atoms ranging from two to four lead formally either to normal N-heteroc... ...
insightful guidance for the design of SAA catalysts for targeted reactions of industrial significance, as illustrated herein for the reduction of nitrogen. Results and discussion Adsorption of adatoms We start by analysing the periodic trends in the adsorption energies of key atomic adsorbates. ...
