The synthesis of N-CF3 compounds through fluorination or trifluoromethylation of N-containing compounds has been extensively investigated. However, general access to N-CF3 compounds simply from N-CF3 secondary amines is hampered by the challenging preparation and instability of these amines, as well as a much lower reactivity due to the strong electron-withdrawing nature and steric bulk of the trifluoromethyl moiety. Herein, we report a general and highly efficient synthesis of N-CF3 secondary amines ...

Almost all current SSVEP–BCIs use a computer screen (CS) to present flickering visual stimuli, which limits its flexible use in actual scenes. Augmented reality (AR) technology provides the ability to superimpose visual stimuli on the real world, and it considerably expands the application scenarios of SSVEP– ...

Therefore, the strategy provides a facile, low-cost, and environmentally friendly method to deploy printed temperature sensors on surfaces of widely varying ...

Laboratory experiments examined how the hydrodynamic interaction between neighboring patches of model vegetation impacted deposition and the potential for patch expansion. The evolution of the vegetated region was modeled experimentally by introducing new artificial vegetation into regions of enhanced deposition. The study began with a pair of side-by-side, circular patches, each of diameter D = 10.5 cm, constructed from circular cylinders (d = 3.2 mm) that extended through the flow depth. The interaction ...

Carbon nanotubes loaded Fe3O4 (CNTs-loaded Fe3O4) composites synthesized via a common chemical vapor deposition method showed excellent electromagnetic wave absorption performance. The effect of different Fe3O4 content on the electromagnetic parameters and wave absorption properties of the CNTs-loaded Fe3O4 composites was investigated. The results indicated that the CNTs-loaded Fe3O4 composites with the content of 42.4% Fe3O4 exhibited the best absorption property among the as-synthesized CNTs-loaded ...

Abstract Fire retardant coatings have been proven effective at reducing the heat release rate (HRR) of structural materials during burning; yet effective methods for increasing the ignition temperature and delay time prior to burning are rarely reported. Herein, a strong, fire‐resistant wood structural material is developed by combining a densification treatment with an anisotropic thermally conductive flame‐retardant coating of hexagonal boron nitride (h‐BN) nanosheets to produce BN‐densified wood. ...

Carbon nanotubes (CNTs) were synthesized on a Ni catalyst–diatomite substrate using a chemical vapor deposition (CVD) method. By controlling the synthesis conditions, we explored the influence of synthesis time and temperature on the synthesis of CNTs. The carbon yield and microstructure of the resulting CNTs were investigated by thermogravity (TG), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Raman spectroscopy analysis. Then, two kinds of purification methods, annealing ...

Abstract This laboratory study examined the influence of particle size and density, and channel velocity on the spatial deposition pattern around an emergent (extending through the entire water depth), circular patch of model vegetation located at the center of a channel. Three flow conditions and three particles of different size and density were considered. Across all particle and velocity conditions, three basic deposition patterns were observed: (1) high deposition in the patch wake and low deposition ...

The use of fragments with low binding affinity for their targets as starting points has received much attention recently. Screening of fragment libraries has been the most common method to find attractive starting points. Herein, we describe a unique, alternative approach to generating fragment leads. A binding model was developed and a set of guidelines were then selected to use this model to design fragments, enabling our discovery of a novel fragment with high LE.

A series of benzo[d]isothiazole-1,1-dioxides were designed and evaluated as inhibitors of HCV polymerase NS5B. Structure-based design led to the incorporation of a high affinity methyl sulfonamide group. Structure–activity relationship (SAR) studies of this series revealed analogues with submicromolar potencies in the HCV replicon assay and moderate pharmacokinetic properties. SAR studies combined with structure based drug design focused on the sulfonamide region led to a novel and potent cyclic ...

For each region, the force balance relationship was established, and the momentum transfer between different regions was presented. ...
