We report a deoxygenative amidation reaction of alcohols with carbamoyl chlorides to afford amides through nickel–photoredox dual catalysis. Good excellent yields can be obtained even for diverse complex sugar and steroid derivatives. The is scalable, the synthetic utility was demonstrated by homologation deliver several important γ-amino synthetically challenging bioactive compound intermediate.
High-reflectivity metallic films on aluminum substrates are crucial in advanced aerospace and military applications due to their excellent reflectivity workability. In order further improve the thermal stability of films, this study investigated deposition AgInCux (x = 1, 3, 5 wt.%) Al 6061 alloy using magnetron sputtering, exploring impact parameters composition optical properties stability. Increased copper content improved stability, while it compromised reflectivity. Additionally,...
Summary A method based on microbial fuel cells ( MFCs ) was used to evaluate the effects of copper Cu 2+ soil microorganisms. Soil spiked with 50–400 mg kg −1 as CuCl 2 incubated for 24 hours before being packed into MFC anode chambers and assayed dehydrogenase activity DHA ), substrate‐induced respiration SIR biomass carbon C mic ). amended 5% w / glucose accelerate ‘start‐up’ improve power generation, followed by 150 operation. Anode biofilm extracted recover total nucleic acids 16S rRNA...
To study the simultaneous removal of Sulfur Dioxide (SO 2 ) and Nitrogen Oxides (NO x from simulated flue gas by wet method, a bubbling device containing calcium hypochlorite (Ca(ClO) solution was used in experiments. In first place, thermodynamic analysis conducted to determine depth reaction process, mechanism desulfurization denitration proposed. After that, experimental results exhibited that SO could be removed Ca(ClO) completely while efficiency NO 41.2%. Moreover, on basis high...
Transition-metal-catalyzed asymmetric allylic alkylation is one of the most powerful and well-known strategies for construction C–C bonds; nevertheless, propargylation elusive remains far less explored. Here, we report copper-catalyzed propargylic substitution N-acyl phenylglycine N-hydroxyphthalimide (NHP) esters racemic carbonates, which afforded multifunctionalized products bearing a terminal alkyne unit in high yields with good stereoselectivities. Moreover, product can be readily...
An effective and friendly method was developed for the production of reducing sugars (RS) from hydrolysis cellulose over solid catalyst Ca-montmorillonite (Mt) grafted by non-acidic ionic liquid (Mt-IL) in water. The effect mass ratio, water dosage, reaction temperature, time were investigated a batch reactor. Raw Mt showed only 7.9% total (TRS) yield catalytic As -SO3H IL, TRS greatly increased under same conditions. highest 35.7% obtained on IL at 200 °C with ratio to 0.2 120 min. high...
ABSTRACT Polyaspartic acid (PASP) is a biodegradable green material with carboxyl groups (COOH) and amido (CONH). In the article, novel urea‐formaldehyde (UF) resin modified by PASP Ca‐montmorillonite (Ca‐Mt) was prepared alkaline‐acid‐alkaline method. The synthesized materials were characterized X‐ray diffraction, Fourier transform‐infrared spectroscopy, thermal analysis (TG‐DTG), scanning electron microscopy. effects of viscosity, curing time, free formaldehyde investigated. results...
<title>Abstract</title> Shallow water problems such as tidal bore, dam-break wave, shallow wave etc. are important for design, construction, and operation of conservancy projects. In this study, a 2-D vertical flow model having strong adaptability the nonlinear free surface describing normally bed source term is established by combining turbulence Youngs-VOF method. The turbulent equations discreted with implicit scheme in coordinate explicit horizontal based on power-law scheme. applied dam...
Abstract Tuberculosis is a major public health threat demanding more than one million lives every year. Many challenges exist to defeat this deadly infectious disease which address the importance of thorough understanding biology causative agent Mycobacterium tuberculosis (MTB). We generated non-redundant pangenome 420 epidemic MTB strains from China. estimate that have 4,278 genes encoding 4,183 proteins, 3,438 are core genes. However, due 99,694 interruptions in 2,447 coding genes, only...
Abstract In this paper, we aimed at developing immobilized cellulase biocatalyst by enhancing the anchor of on support surface. A mesoporous Zr-based MOF was first synthesized biomineralization method using dextran as template. The resultant PVP-cellulase@CD-UIO-66-Zr exhibited a high loading capacity 265 mg g − 1 support. physical adsorption CD-UIO-66-Zr could be further enhanced capping with PVP. About 83% activity retained after six cycles, and its equilibrium leakage ratio 36% during...
Tween 60 and 80 as dispersant had been adding in the preparation process to increase surface area of VPO catalysts. XRD、 XPS TEM characterization tests show that crystalline phase catalyst surfactant are different from did not. Although two types (VO) 2 P O 7 but their microscopic structures found former is 35-40m / g, while without surfactants only 19m g.
Making VPO catalyst in the condition of different concentrations Phosphoric acid and temperatures，determine average valence vanadium. with method Potassium permanganate-Ferrous ammonium sulfate, to investigate effect concentration phosphoric on catalyst, under temperatures. The structure, composition, crystal, Particle size has been characterized by XRD SEM. results confirmed that compare higher acid，the were made lower had low valence, greater specific surface area, better crystallinity,...
Epigenetic modifications play an important role in the regulation of senescence. N6-methyladenosine (m6A) is most abundant modification mRNA. However, impact m6A on senescence remains largely unknown at animal individual level. Standard model organisms Caenorhabditis and Drosophila lack many gene homologs vertebrate system that are present other invertebrates. In this study, we employed a small aquatic invertebrate Brachionus plicatilis which has been used aging studies for nearly 100 years...
