Abstract Owing to the strong nucleophilicity of NH 2 group, free‐NH glycinates react with MBH acetates usually deliver N‐allylated products even in absence catalysts. Without protection chiral pyridoxal catalysts bearing an amide side chain at C3 position naphthyl ring switched chemoselectivity from intrinsic N‐allylation α‐C allylation. The reaction formed multisubstituted glutamic acid esters as S N 2′–S 2′ good yields excellent stereoselectivity (up 86 % yield, >20 : 1 dr, 97 ee). As...
Abstract Submicrometer‐sized 2,6‐diamino‐3,5‐dinitropyrazine‐1‐oxide (LLM‐105) crystals were prepared by spray‐crystallization method with dimethyl sulfoxide (DMSO) and ultra‐pure water surfactant as the solvent anti solvent, respectively. LLM‐105 particles characterized scanning electron microscopy (SEM), X‐ray diffraction (XRD), particle size analysis. The thermal stability sensitivity properties of submicrometer‐sized also investigated. results revealed that are spherelike in morphology a...
In order to evaluate the effects of carbohydrate levels on growth, glycometabolism, antioxidant capacity and metabolome largemouth bass (Micropterus salmoides), two test diets were prepared with 100 g kg−1 α-starch (LS group) 200 (HS respectively. Largemouth an initial weight 7.56 ± 0.02 was fed for 8 weeks. Comparing LS group, in HS gain (WG), specific growth rate (SGR) feed conversion ratio (FCR) significantly reduced, protein efficiency (PER) improved, plasma aspartate aminotransferase...
Aiming at the electrical safety problem of a high-voltage lithium-ion battery system caused by an arc, and based on establishment arc fault experimental platform, evolution law in negative terminal under different working conditions is discussed. On this basis, model magnetohydrodynamics established to analyze arc’s electro-thermal coupling characteristics further obtain distribution multi-physical field. The results show that generated grade pack will break down cell’s shell form hole,...
<sec>In order to meet the switching requirements of high-frequency pulsed-power systems and further enhance peak power turn-on speed solid-state switches, comparative experiments on structure optically controlled multi-gate thyristors parameter injected light are investigated in this work. The research results show that semiconductor chips based thyristor exhibit different conduction characteristics under varying laser injection conditions, resulting unique inflection point curves. By...
In the cyclodextrins family, native α-cyclodextrin has almost been abandoned in capillary electrophoresis chiral separation due to its much weaker enantioselectivity compared with β-cyclodextrin and their derivatives. this work, several amino acid ionic liquids were selected establish synergistic enantioseparation systems α-cyclodextrin. Enhanced enantioselectivities observed liquids/α-cyclodextrin single system. A series of comparison experiments performed demonstrate superiority systems....
Cosmography can be used to constrain the kinematics of Universe in a model-independent way. In this work, we attempt combine Padé approximations with latest Pantheon+ sample test cosmological principle. Based on approximations, first applied cosmographic constraints different-order polynomials including third-order (Padé (2, 1) ), fourth-order 2) and fifth-order (3, ) ones. The statistical analyses show that polynomial has best performance. Its fits are H 0 = 72.53 ± 0.28 km s −1 Mpc , q...
Systems of second-order linear ordinary differential equations (ODEs) to arbitrary input functions appear in many fields physics and engineering. Numerical methods for solving these kinds problems have been mainly performed the time frequency domains. In contrast, this paper develops an efficient, seminumerical pole-residue method implemented Laplace domain. article, a key concept development is on how compute poles residues output from those system transfer functions. Once are known,...
On-site protein analysis is crucial for disease diagnosis in community and family medicine which microfluidic paper-based analytical devices (μPADs) have attracted growing attention. However, the practical applications of μPADs physiological samples with high complexity still limited. Herein, we developed a three-dimensional (3D) isoelectric focusing (IEF) platform, composed power supply, reservoirs, separation channel made by origami stacking method, to simultaneously separate enrich...
Developing miniaturized and rapid protein analytical platforms is urgently needed for on-site analysis, which important disease diagnosis monitoring. Liquid marbles (LMs), a kind of particle-coated droplets, as ideal microreactors have been used in various fields. However, their application limited due to the difficulty pretreating complex samples simple LMs. Herein, inspired by microfluidic chip, we propose strategy through fabricating fluid channels using deformable LM, termed liquid...
A fractured rock mass was characterized by strong heterogeneity, discontinuity, and anisotropy. The study of flow in a complex challenging task. As the main seepage channels mass, fracture network mainly affected density, trace length, aperture, direction angle. In this paper, influence parameters on permeability studied orthogonal experimental design numerical modeling. series networks were established to obtain rules permeability. results showed that increase aperture increased model angle...
