Physicians have long been calling for an inherent antimicrobial wound dressing, which will be a great progress treating complicated infections. Here, we report novel bioadhesive hydrogel with antibacterial properties prepared by mixing modified hyaluronic acid (HA) and ε-polylysine (EPL). This can effectively kill Gram (+) (−) bacteria its high positive charge density on the surface. The sol–gel transition occurs within seconds via horseradish peroxidase enzymatic cross-linking Schiff base...
Abstract The past century has witnessed a large number of reports on the Z / E isomerization alkenes. However, vast majority them are still limited to di- and tri-substituted stereospecific tetrasubstituted alkenes remains be an underdeveloped area, thus lacking in stereodivergent synthesis axially chiral Herein we report atroposelective alkene analogues by asymmetric allylic substitution-isomerization, followed their via triplet energy transfer photocatalysis. In this regard, N...
Emerging organic pollutants and refractory in water bodies have caused severe harm to the ecological environment human health. Electrochemical advanced oxidation processes (EAOPs) are currently one of most effective methods deal with pollutants. Electrode materials serve as critical component influencing EAOP performance. Dimensionally stable anodes (DSAs) advantages dimensional stability, structural diversity, chemical low oxygen evolution potential long service life, etc. Herein, several...
Some novel Brønsted acidic ionic liquids (TSILs) that bear an alkane sulfonic acid group in acyclic trialkanylammonium cation were synthesized and their uses as dual solvent−catalysts for Fischer esterification reactions of acetic acid, metacetonic benzoic with ethanol, butanol, benzyl alcohol investigated. The completed smoothly at room temperature to 110 °C 1.5−3.0 h good yields 88−95%. results indicate catalytic activity depends on anion acidity the solubility starting material TSILs....
Axially chiral molecules bearing multiple stereogenic axes are of great importance in the field organic chemistry. However, efficient construction atropisomers featuring two different types has rarely been explored. Herein, we report novel atroposelective synthesis configurationally stable axially B,N-heterocycles. By using stepwise asymmetric allylic substitution-isomerization (AASI) strategy, diaxially B,N-heterocycles B-C and C-N that related to moieties enamines arylborons were also...
Three types of energetic materials with high nitrogen content, decomposition temperature and good detonation properties were obtained.
Millions of in-service concrete bridges around the world are exceeding their design life. Corrosion may lead to a sudden fracture prestressing steels, and understanding fatigue behavior corroded prestressed (PC) is essential. Accordingly, an effective analytical model for PC beams needed. In this study, experimental investigation beams, was carried out. Thirteen had experienced acceleration corrosion before high-cycle testing. All failed due tensile steel bars, three-dimensional laser...
Abstract Axially chiral N ‐substituted quinazolinones are important bioactive molecules, which presented in many synthetic drugs. However, most strategies toward their atroposelective synthesis mainly limited to the axially arylquinazolinone frameworks. The development of modular methods access diverse quinazolinone‐based atropisomers remains scarce and challenging. Herein, we report regio‐ ‐vinylquinazolinones via strategy asymmetric allylic substitution‐isomerization. catalysis system...
An understanding of how corrosion affects fatigue behavior reinforced concrete (RC) structures is essential for lifetime-oriented maintenance and design existing bridges. This paper covers an experimental investigation on corroded RC beams. Corrosion in six beams was artificially accelerated by the impressed current method before loading administered. All failed with fracturing their tension steel bars. The test results indicated that more severe bars was, sooner failed. determines...
Corrosion of stirrups is always more severe than longitudinal steel bars, leading to possible shear failure instead bending failure. This paper covers the authors' investigation on effects stirrup corrosion behaviour reinforced concrete beams. Based modified compression field theory, a method whole process analysis was developed showing beams with corroded stirrups. Of particular interest cracking damage cross sections, loss cross-sectional area and deterioration mechanical properties After...
Fe-based materials containing Fe-Nx sites have emerged as promising electrocatalysts in the oxygen reduction reaction (ORR), but they still suffer structural instability which may lead to loss of catalytic activity. Herein, a novel electrocatalyst Fe3C-FeSA@3DCN with coexistence Fe3C nanoparticles and Fe single atoms (FeSA) three-dimensional conductive network (3DCN) is prepared via lattice confinement defect trapping strategies an atomic loading high 4.36%. In ORR process, limiting current...
Compounds containing dinitromethyl groups are ideal structural units for energetic materials due to their high density and good oxygen balance. However, these compounds often have drawbacks, such as low decomposition temperatures mechanical sensitivity, which limit practical applications in materials. In order address issues, a series of novel nitrogen- oxygen-rich 7–11 been successfully designed by incorporating amino enhance hydrogen bonding. Among them, compound 8 exhibited an excellent...
Heat-resistant energetic compounds are of great importance in the field material chemistry. Here, we report a practical synthesis series fused-ring via combination 1,2,3-triazine N-oxide and 2,4,6-trinitroaniline moieties. Starting from known compound 4,6-diamino-2-chloropyrimidine-5-carbonitrile (1), nucleophilic substitution followed by one-step nitration introduced three nitro groups onto benzene ring moiety, simultaneously. The resulting 4-7 exhibited high decomposition temperature (Td >...
