Selective hydrogenation of C=C and C=O bonds in cinnamaldehyde (CAL) to produce desired products is a challenging task due to the complex conjugate system of the two unsaturated functional groups.In this study,a simple ball milling method is presented for synthesizing Pt-based single-atom alloy catalysts (SAAs) that can function as a control switch for the selective hydrogenation of CAL into highly valuable products.

As the third generation new battery,the power conversion efficiency(PCE)of metal halide perovskite solar cells(PsCs)has increased from 3.8%in 2009 to 25.8%currently certified,which fully shows that they have great research value and development prospect.As one of the main components of high-efficiency PSCs,hole transport materials(HTMs)play an important role in extracting and transporting holes and inhibiting charge recombination.However,commonly used HTMs require doping,and the hygroscopicity and corrosiveness of the dopants will destroy the stability of PsCs and hinder their commercialization.Therefore,it is of great significance to develop dopant-free HTMs.

Numerous Internet of Things(IoT)systems produce massive volumes of information that must be handled and answered in a quite short period.The growing energy usage related to the migration of data into the cloud is one of the biggest problems.Edge computation helps users unload the workload again from cloud near the source of the information that must be handled to save time,increase security,and reduce the congestion of networks.Therefore,in this paper,Optimized Energy efficient Strategy(OEES)has been proposed for extracting,distributing,evaluating the data on the edge devices.In the initial stage of OEES,before the transmission state,the data gathered from edge devices are supported by a fast error like reduction that is regarded as the largest energy user of an IoT system.The initial stage is followed by the reconstructing and the processing state.The processed data is transmitted to the nodes through controlled deep learning techniques.The entire stage of data collection,transmission and data reduction between edge devices uses less energy.The experimental results indicate that the volume of data transferred decreases and does not impact the professional data performance and predictive accuracy.Energy consumption of 7.38 KJ and energy conservation of 55.57 kJ was found in the proposed OEES scheme.Predictive accuracy is 97.5 percent,data performance rate was 97.65 percent,and execution time is 14.49 ms.

Organic photovoltaics(OPVs)have attracted much attention because of the advantages in low-cost and large-area fabrication and the great potentials in achieving flexible and semi-transparent devices(1)However,compared with inorganic and perovskite solar cells[2],OPVs show relatively low photoelectric conversion efficiencies,which is admittedly attributed to intrinsically low dielectric constants of organic materials[3]resulting in large energy losses(Eloss=EgqVoc,where Eg is the optical bandgap of the photoactive layer,Voc is the open-circuit voltage of photovoltaic devices and q is elementary charge).

Tea plants grow in acidic soil, but to date, their intrinsic mechanisms of acidic stress tolerance have not been elucidated. Here, we assessed the tea plant response to growth on NHt4 nutrient media having different p H and iron levels. When grown in standard NHt4 nutrient solution(iron insufficient, 0.35 mg Là1 Fe2t), tea roots exhibited significantly lower nitrogen accumulation, plasma membrane Ht-ATPase activity, and protein levels; net Htefflux was lower at pH 4.0 and 5.0 than at pH 6.0. Addition of30 mg Là1 Fe2t(iron sufficient, mimicking normal soil Fe2tconcentrations) to the NHt4 nutrient solution led to more efficient iron plaque formation on roots and increased root plasma membrane Ht-ATPase levels and activities at p H 4.0 eland 5.0, compared to the p H 6.0 condition. Furthermore,plants grown at pH 4.0 and 5.0, with sufficient iron,exhibited significantly higher nitrogen accumulation than those grown at pH 6.0. Together, these results support the hypothesis that efficient iron plaque formation, on tea roots, is important for acidic stress tolerance. Furthermore,our findings establish that efficient iron plaque formation is linked to increased levels and activities of the tea root plasma membrane Ht-ATPase, under low pH conditions.

Millions of people in poor areas are still under the threat of fluoride contamination.How to effectively separate fluorine in water is an important step to reduce the ecological risk.In this paper,we performed a systematic DFT calculation focused on the defluorination behavior between the LiAl-and MgAl-LDHs.The results indicated that the LiAl-LDHs exhibited high chemical activity before the defluorination,because of the better electronic structure.After the defluorination,the LiAl-LDHs with adsorbed-F–were also more stable than the MgAl-LDHs.In addition,the existence of coordination covalent bond for the adsorbed-F–attached to the LiAl-LDHs was confirmed.This is an important reason for the high defluorination efficiency by the LiAl-LDHs.In addition,a series of weak interaction,including hydrogen bond and van der Waals interaction were also observed.Finally,a LiAl-LDHs with excellent fluoride removal properties were synthesized well by simple hydrothermal method.The results showed that our synthesized LiAl-LDHs with the capacity of 156.09 mg/g,could be effectively defluorinated in water.Notably,it surpasses most materials and has potential applications.

Targeting-induced local lesions in genomes(TILLING)is a powerful reverse-genetics tool that enables high-throughput screening of genomic variations in plants.Although TILLING has been developed for many diploid plants,the technology has been used in very few polyploid species due to their genomic complexity.Here,we established an efficient capillary electrophoresis-based TILLING platform for allotetraploid cultivated tobacco(Nicotiana tabacum L.)using an ethyl methanesulfonate(EMS)-mutagenized population of 1,536 individuals.We optimized the procedures for endonuclease preparation,leaf tissue sampling,DNA extraction,normalization,pooling,PCR amplification,heteroduplex formation,and capillary electrophoresis.In a test screen using seven target genes with eight PCR fragments,we obtained 118 mutants.The mutation density was estimated to be approximately one mutation per 106kb on average.Phenotypic analyses showed that mutations in two heavy metal transporter genes,HMA2S and HMA4T,led to reduced accumulation of cadmium and zinc,which was confirmed independently using CRISPR/Cas9 to generate knockout mutants.Our results demonstrate that this powerful TILLING platform(available at http://***)can be used in tobacco to facilitate functional genomics applications.

Realization of robust quantum computing is a tremendous task.On one hand,one must reduce errors as many as possible using various means[1-3];on the other hand,one may make large error rates tolerable via fault-tolerant implementation.In achieving tolerant against noises,the cost to pay is the increased number of gates used.Therefore,an efficient implementation of fault-tolerant gates is crucial.As already evidenced,Clifford gates with a T gate can form a universal set of fault-tolerant gates.
