Reduction of CO 2 to methanol using renewable hydrogen is a promising but challenging strategy for carbon capture and utilization.
Conversion of CO2 to value-added chemicals has been a long-standing objective, and direct hydrogenation lower olefins is highly desirable but still challenging. Herein, we report selective conversion through over ZnZrO/SAPO tandem catalyst fabricated with ZnO-ZrO2 solid solution Zn-modified SAPO-34 zeolite, which can achieve selectivity for as high 80–90% among hydrocarbon products. This realized on the basis dual functions catalyst: production SAPO zeolite. The thermodynamic kinetic...
Hydrogenation of CO2 to methanol utilizing the hydrogen from renewable energy sources offers a promising way reduce emissions through utilization as carbon source. However, it is challenge convert with high activity and selectivity. Herein, we report class metal-oxide solid-solution catalysts: MaZrOx (Ma = Cd, Ga), which show selectivity up 80% single pass conversion reaching 4.3%–12.4% under reaction conditions H2/CO2 3/1, 24 000 h–1, 5 MPa. Structural electronic characterizations combined...
Stable 2-D metal-organic framework nanosheets were utilized as a superior clean-background matrix for MALDI-TOF MS analysis of small biomolecules and pollutants in both positive negative ion modes. The could unusually afford up to 1000 mM the salt concentrations monitoring enzymatic hydrolysis neurotransmitter acetylcholine.
Dynamic vision sensor (DVS) is a new type of image sensor, which has application prospects in the fields automobiles and robots. sensors are very different from traditional terms pixel principle output data. Background activity (BA) data will affect quality, but there currently no unified indicator to evaluate quality event streams. This paper proposes method eliminate background activity, performance index for evaluating filter performance: noise real (NIR) (RIN). The lower value, better...
Optical remote sensing images are widely used in the fields of feature recognition, scene semantic segmentation, and others. However, quality is degraded due to influence various noises, which seriously affects practical use images. As have more complex texture features than ordinary images, this will lead previous denoising algorithm failing achieve desired result. Therefore, we propose a novel image network (RSIDNet) based on deep learning approach, mainly consists multi-scale extraction...
Abstract Background While multiple replication origins have been observed in archaea, considerably less is known about their evolutionary processes. Here, we performed a comparative analysis of the predicted (proved part) orc/cdc6 -associated 15 completely sequenced haloarchaeal genomes to investigate diversity and evolution halophilic Archaea. Results Multiple were all analyzed following identification putative ORBs (origin recognition boxes) that are associated with genes. Five these...
An efficient and convenient method is developed for the synthesis of 2-trifluoromethyl benzimidazoles using Cu 2 O as pre-catalyst. The reaction mechanism involving a seven-membered cyclic diimine intermediate was thoroughly investigated.
Ruthenium catalyzed oxidative dearomatization-hydroxylation of N-Boc indoles for the synthesis 2-hydroxyindolin-3-ones was described. The can be transformed into with RuCl3·3H2O as catalyst, p-toluenesulfonic acid (TsOH·H2O) promoter and tert-butyl peroxide (TBHP, 3.0 equiv) oxidant in acetonitrile. mechanism had been proposed on basis control experiments isolation intermediate.

The InCl3/TfOH-mediated tandem Knoevenagel condensation–deacylation sequence various 2-oxindoles with 1,3-diones or acetoacetate furnished satisfactory to excellent yields (up >99% yield). Employing reaction system, condensation ketones aldehydes also proceeded smoothly produce 3-alkylideneoxindoles. This protocol can be amenable scale up. effect acids on intermolecular competition...

Abstract Carboxylation of arenes utilizing CO 2 into value‐added chemicals has received much attention but remains a challenge. Herein, we report Ti−Zr oxide catalyst which shows high activity in the carboxylation toluene with ‐derived dimethyl carbonate (DMC) methyl methylbenzoates, while individual TiO and ZrO component show poor catalytic performance. It was found that excellent performance is related to amorphous state mixed‐metal possesses acidity moderate basicity together specific...
