Single-atom catalysts exhibit high selectivity in hydrogenation due to their isolated active sites, which ensure uniform adsorption configurations of substrate molecules. Compared with the achievement catalytic selectivity, there is still a long way go exploiting activity single-atom catalysts. Herein, we developed highly and selective by embedding Pt single atoms surface Ni nanocrystals (denoted as Pt1/Ni nanocrystals). During 3-nitrostyrene, TOF numbers based on reached ∼1800 h–1 under 3...

This study aimed to investigate the effects of expansion pretreatment on chemical structure and reaction characteristics tobacco pyrolysis. Systematic characterization pretreated feedstock was conducted analyze changes in physicochemical properties feedstock. The thermal conductivity specific heat capacity decreased significantly after pretreatment. Furthermore, average pore diameter volume increased, leading a significant enlargement surface area from 0.18 0.46 m2/g, which consequently...
We present a versatile platform for the synthesis of functional polyacetals from sugar and furfuryl alcohol derivatives using controlled cascade enyne metathesis polymerization. A range monomers with defined stereochemistry were explored that featured broad group tolerance. The polymerization showed living character permitted preparation functionalized targetable molecular weights more complex architectures. In addition, by harnessing chiral nature starting materials, method granted facile...

Abstract Rhodium (Rh) is well‐known for its catalytic application in diverse industrial reactions such as methane conversion, hydrogen generation, and olefin hydroformylation. Compared to homogeneous catalysts, heterogeneous Rh‐based nanocatalysts are facilely separated collected after reactions, thus being more compatible industrialization. To this end, the development of active stable catalysts has received everlasting interest. In review, we focus on synthesis catalysis. Recent efforts...
Objective: Astaxanthin is a natural super antioxidant. The present study was carried out to investigate the effect of astaxanthin rich <i>Phaffia rhodozyma</i> (PR) supplementation in diets on laying production performance, egg quality, antioxidant defenses and immune hens.Methods: A total five hundred twelve 60-week-old Lohmann Brown hens (2,243±12 g) were randomly assigned four groups, each including 4 replicates with 32 birds per replicate. PR added corn-soybean meal produce...
In the present work, experimental and kinetic studies are conducted to explore model tobacco pyrolysis characteristics under a wide range of heating conditions. First, thermal decomposition processes sample were investigated using thermogravimetric analysis/difference thermogravimetry (TGA/DTG) experiments rates (10-500 K/min), TGA/DTG profiles compared highlight effect rate on characteristics. The results showed that was sufficiently devolatilized at 1173.15 K (900 °C) final volatiles...
Background: The regulatory effects of carbon nanomaterials (CNMs) on plant growth and their potential applications in agriculture have attracted a great deal attention from researchers. CNMs been shown to promote nutrient absorption increase growth. However, the mechanisms by which affect are still unknown. Methods: tobacco seedling biomass, potassium (K+) concentration, accumulation hydroponic were investigated exposure nanoparticles (CNPs). To directly observe effect CNPs K+ uptake roots,...
The thermal decomposition of extractives can yield additional products, resulting in a different final product distribution bio-oil, especially for extractives-rich biomass. However, the decompositon behavior themselves has long been ignored, but deserves deep investigation. Herein, non-linear stepwise heating program based on Gaussian multi-peak fitting differential thermogravimetric curve biomass was designed. Using this program, pyrolysis process chemical substances effectively decoupled...
A methodology for predicting proximate and ultimate analysis data was developed by using near-infrared spectroscopy (NIR) combined with chemometric methods. The quantitative model has high accuracy, as evidenced low root-mean-square-error of prediction (RMSEP) values (e.g., 0.41% volatile matter 0.29% carbon). further applied to tobaccos distinct aroma profiles, the predicted lead classification 86.6% accuracy. This can be expanded discrimination imported from Brazil, United States, Canada,...
As the most basic indexes to evaluate quality of tobacco, contents routine chemical constituents in tobacco are mainly detected by continuous-flow analysis at present. However, this method suffers from complex operation, time consumption, and environmental pollution. Thus, it is necessary establish a rapid accurate detection method. Herein, different ongoing research studies that chose near-infrared spectroscopy as information source for quantitative components we proposed first use...
Two new discrete Btz-bridged pentanuclear metal complexes, [HDMF][NaHg4(Btz)6I4] (1) and [Zn5(Btz)6(L)3(Ac)] · 0.5MeOH 0.5H2O (2) (Btz = deprotonated benzotriazole, L p-aminobenzoate, HDMF protonated DMF, Ac acetate), were synthesized using three-layered diffusion natural evaporation methods, respectively.
