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...
A dynamical response of the current-voltage characteristics of ropes and individual structures of multiwalled nitrogen-doped carbon nanotubes has been observed inside a transmission electron microscope. The drastic change of the current transport properties is thought to be due to purging of contaminating...
a The structure of the octahedral cage Co6L46+ (H1) showing the large cavity volume and robust openings. b The simulation structure of cage Co6L46+ with fluorescein encapsulated showing the relative positions. c ESI–MS spectra of metal-organic capsule H1 (1.0 mM) in a CH3CN solution...
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...
Electrochemical reduction of oxygen molecules can produce H2O2, which is an important chemical for a green and sustainable society; therefore, the development of catalysts for this reaction is necessary. We propose mesoporous nitrogen-doped carbon prepared from (1-methyl-1H-pyrrole-2-yl)methanol in ...
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...
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
The residual MSA in the films was removed by immersing them in deionized water, followed by drying in nitrogen flow. PEDOT:PSS, ethylene glycol, (3-glycidyloxypropyl)trimethoxysilane and 4-dodecylbenzenesulfonic acid were mixed in the volume ratio of 100:5:1:0.1 and sonicated for 10 min....
We have built a liquid nitrogen cooled low temperature stage for scanning electron microscopes, which is specially designed for the study of high transition temperature (Tc) superconducting devices and circuits in very small and stable magnetic fields. For effective magnetic shielding of the sample we...
