The C-3 sulfenylation reaction of indoles has been achieved under mild conditions by simply employing NaOH as promoter and thiols thiolating reagents. This simple method allows for easy rapid synthesis various 3-sulfenylated with generally good to excellent yields. Primary attempts in scale-up give satisfactory result.
Molecular simulations have been performed on adsorption equilibria and diffusivities of pure mixed-gases ethanol/water in micropores an NaA zeolite crystal by using the μVT-ensemble orientational-bias Monte Carlo NVT-ensemble equilibrium molecular dynamics techniques. The temperature total pressure were set at 378 K 0.1 MPa respectively for comparison with data vapor permeation a corresponding system. Adsorption selectivity water to ethanol was found increase increasing composition gas...
Magnetic field gradients reduce the transverse relaxation time of nuclear spins, which usually degrades sensitivity atomic sensors based on spins. We demonstrate improved magnetic gradient compensation by applying first-order and second-order simultaneously in a cubic vapor cell containing 87Rb 129Xe gas. Compared with only compensation, is up to 4.3 times longer when both compensating gradients, indicates that total greatly suppressed joint our experiment. The induced polarized static...

o-Aminophenol (OAP) has been discovered as practical precursor of directing group (DG) in the palladium-catalyzed aromatic C–H arylation benzamides. This newly identified, simple, and low cost DG exhibited broad substrate tolerance rapid synthesis various o-arylated benzamides via direct assemblies benzoyl chlorides, aryl iodides, different o-aminophenols form step economical multicomponent reaction.
Molecular dynamics simulations of oxygen molecules in NaOH and KOH solutions at different temperatures (25-120 degrees C) concentrations (1:100-1:5, molar ratios) were performed this study. The interactions with the surrounding solvent solute clarified by considering solvent-solvent, oxygen-solvent, oxygen-solute radial distribution functions. self-diffusion coefficients both determined analyzing mean-squared displacement (MSD) curves, using Einstein's relationship. It was concluded that all...

Abstract Through the comprehensive analysis of ab initio and experimental results a large number diatomic systems, systematic deviation method in vibrational energies prediction caused by physical/mathematical simplification is located. A joint machine learning based on information across molecules proposed to deal with problem. Starting from an model, then systematically modifying it through learning, many systems (SiC, HBr, NO, PC, N 2 , SiO, O ClF, etc.) have been improved, significantly...
We describe an analytical design method of shielding-coupled uniform magnetic coils for miniature quantum devices. The theoretical and simulation results point out that the 99% range along symmetrical axis 50% radius proposed m = 3 are uniform, more important is both uniformity region these kinds can be systematically improved only by adding loops at specific places obtained from our formula. A relevant experiment demonstrates feasibility this realizes with inhomogeneity below 2.6 × 10-3...

We give a detailed rigorous theoretical derivation by using perturbation-iteration demonstrate rationality this measuring method. Then,...
We analyze the scale factor linearity, steady-state, transient, and noise characteristics of a nuclear magnetic resonance oscillator coupled with phase-locked loop, which makes its performance improvement possible by balanced strategy in optimizing parameters based on proposed model. The numerical simulation indicates that simple system gives better linearity transient response than system, while steady-state solution is similar between two experimental validation. phase suppression...
