1Synergistic cerium doping and MXene coupling in layered double hydroxides as efficient electrocatalysts for oxygen evolution显示文摘Oxygen evolution reaction(OER) is a bottle-neck process in many sustainable energy conversion systems due to its sluggish kinetics.The development of cost-effective yet efficient electrocatalysts towards OER is highly desirable but still a great challenge at current stage.Herein,a new type of hybrid nanostructure,consisting of two-dimensional(2D) Cerium-doped NiFe-layered double hydroxide nanoflakes directly grown on the 2D Ti3C2Tx MXene surface(denoted as NiFeCe-LDH/MXene),is designed using a facile insitu coprecipitation method.The resultant NiFeCe-LDH/MXene hybrid presents a hierarchical nanoporous structure,high electrical conductivity and strong interfacial junction because of the synergistic effect of Ce doping and MXene coupling.As a result,the hybrid catalyst exhibits an excellent catalytic activity for OER,delivering a low onset overpotential of 197 mV and an overpotential of 260 mV at a current density of 10 mA·cm-2 in the alkaline medium,much lower than its pure LDH counterparts and IrO2 catalyst.Besides,the hybrid catalyst also displays a fast reaction kinetics and a remarkable stable durability.Further theoretic studies using density function theory(DFT) methods reveal that Ce doping could effectively narrow the bandgap of NiFe-LDH and reduce the overpotential in OER process.This work may shed light on the exploration of advanced electrocatalysts for renewable energy conversion and storage systems.Yangyang Wen Zhiting Wei Jiahao Liu Rui Li Ping Wang Bin Zhou Xiang Zhang Jiang Li Zhenxing Li 2021Journal of Energy Chemistry2021,30,1:4

3A review on SRAM-based computing in-memory:Circuits,functions,and applications显示文摘Artificial intelligence(AI)processes data-centric applications with minimal effort.However,it poses new challenges to system design in terms of computational speed and energy efficiency.The traditional von Neumann architecture cannot meet the requirements of heavily datacentric applications due to the separation of computation and storage.The emergence of computing inmemory(CIM)is significant in circumventing the von Neumann bottleneck.A commercialized memory architecture,static random-access memory(SRAM),is fast and robust,consumes less power,and is compatible with state-of-the-art technology.This study investigates the research progress of SRAM-based CIM technology in three levels:circuit,function,and application.It also outlines the problems,challenges,and prospects of SRAM-based CIM macros.Zhiting Lin Zhongzhen Tong Jin Zhang Fangming Wang Tian Xu Yue Zhao Xiulong Wu Chunyu Peng Wenjuan Lu Qiang Zhao Junning Chen 2022Journal of Semiconductors2022,43,3:2
4Upstream CRP-binding site is not essential for CRP-cAMP-mediated inhibition on the nifU promoter显示文摘When the NifA-mediated activation of Kleb-siella pneumontae nifU promoter is recreated in Escherichia coli, it has been observed that CRP-cAMP has an inhibitory effect on the nifU promoter. Sequence analysis indicates that there is a strong CRP-binding site located upstream of the nifU promoter, overlapping completely with a previously identified Nif A-binding site. In vitro gel retardation analysis indicates that this putative CRP-binding site has similar affinity for CRP, when compared with that at the lac promoter, suggesting that CRP could effectively compete with NifA for such a binding site under physiological conditions. When this putative CRP-binding site on nifU was mutated, in vitro gel retardation analysis indicates that CRP can no longer bind to the mutant promoter. However, when constitutively expressed NifA is used as the activator, CRP-cAMP-mediated inhibitory effect on this mutant nifU promoter has no significant difference when compared with that obtained from its wild-type promoter.LI Zhiting ZHANG Weijia WANG Yiping 2002Chinese Science Bulletin2002,47,21:1

7Genome assembly and resequencing analyses provide new insights into the evolution, domestication and ornamental traits of crape myrtle显示文摘Crape myrtle(Lagerstroemia indica)is a globally used ornamental woody plant and is the representative species of Lagerstroemia.However,studies on the evolution and genomic breeding of L.indica have been hindered by the lack of a reference genome.Here we assembled the first high-quality genome of L.indica using PacBio combined with Hi-C scaffolding to anchor the 329.14-Mb genome assembly into 24 pseudochromosomes.We detected a previously undescribed independent whole-genome triplication event occurring 35.5 million years ago in L.indica following its divergence from Punica granatum.After resequencing 73 accessions of Lagerstroemia,the main parents of modern crape myrtle cultivars were found to be L.indica and L.fauriei.During the process of domestication,genetic diversity tended to decrease in many plants,but this was not observed in L.indica.We constructed a high-density genetic linkage map with an average map distance of 0.33 cM.Furthermore,we integrated the results of quantitative trait locus(QTL)using genetic mapping and bulk segregant analysis(BSA),revealing that the major-effect interval controlling internode length(IL)is located on chr1,which contains CDL15,CRG98,and GID1b1 associated with the phytohormone pathways.Analysis of gene expression of the red,purple,and white flower-colour flavonoid pathways revealed that differential expression of multiple genes determined the flower colour of L.indica,with white flowers having the lowest gene expression.In addition,BSA of purple-and green-leaved individuals of populations of L.indica was performed,and the leaf colour loci were mapped to chr12 and chr17.Within these intervals,we identified MYB35,NCED,and KAS1.Our genome assembly provided a foundation for investigating the evolution,population structure,and differentiation of Myrtaceae species and accelerating the molecular breeding of L.indica.Yang Zhou Tangchun Zheng Ming Cai Lu Feng Xiufeng Chi Ping Shen Xin Wang Zhiting Wan Cunquan Yuan Man Zhang Yu Han Jia Wang Huitang Pan Tangren Cheng Qixiang Zhang 2023Horticulture Research2023,10,9:1

11Effect of Exogenous Lanthanum on Accumulation of Cadmium and Its Chemical Form in Tomatoes显示文摘In the condition that soil is polluted by Cd(20 mg·L-1),two varieties of tomato(Lycopersicon esculintum Mill.)(plant high Cd-enriched variety(Yufen109)and plant low Cd-enriched variety(4641))treated with LaCl3 of different concentration(0,10 and 20mg·L-1)were determined for their effect on plant dry weight,anti-oxidase activity(CAT,SOD and POD),tomato fruit Cd chemical form and Cd accumulation.The results show that 10 mg?L-1LaCl3 can increase dry weight of plant at various positions and can reduce the concentration of Cd of different forms.Spraying with LaCl3(10,20 mg·L-1)can reduce Cd concentration in leaves,stems,roots and fruits of tomato plants with lowering rates of 13.7%-31.9%,9.5%-30.6%,10.8%-44.5%and 19.4%-37.0%,respectively.Suitable amount of lanthanum(10 mg·L-1 LaCl3)can increase yield of tomatoes,reduce Cd accumulation in the fruit.In the two tomato varieties,Lanthanum and Cadmium react interactively,expressing to be coexisting of both synergism and antagonistic.XIE Wenwen XIONG Shijuan XU Weihong CHEN Rong ZHANG Jinzhong XIONG Zhiting 2014Wuhan University Journal of Natural Sciences2014,19,3:0
12Insights into the architecture of human-induced polygenic selection in Duroc pigs显示文摘Background:As one of the most utilized commercial composite boar lines,Duroc pigs have been introduced to China and undergone strongly human-induced selection over the past decades.However,the efficiencies and limitations of previous breeding of Chinese Duroc pigs are largely understudied.The objective of this study was to uncover directional polygenic selection in the Duroc pig genome,and investigate points overlooked in the past breeding process.Results:Here,we utilized the Generation Proxy Selection Mapping(GPSM)on a dataset of 1067 Duroc pigs with 8,766,074 imputed SNPs.GPSM detected a total of 5649 putative SNPs actively under selection in the Chinese Duroc pig population,and the potential functions of the selection regions were mainly related to production,meat and carcass traits.Meanwhile,we observed that the allele frequency of variants related to teat number(NT)relevant traits was also changed,which might be influenced by genes that had pleiotropic effects.First,we identified the direction of selection on NT traits by G,and further pinpointed large-effect genomic regions associated with NT relevant traits by selection signature and GWAS.Combining results of NT relevant traits-specific selection signatures and GWAS,we found three common genome regions,which were overlapped with QTLs related to production,meat and carcass traits besides“teat number”QTLs.This implied that there were some pleiotropic variants underlying NT and economic traits.We further found that rs346331089 has pleiotropic effects on NT and economic traits,e.g.,litter size at weaning(LSW),litter weight at weaning(LWW),days to 100 kg(D100),backfat thickness at 100 kg(B100),and loin muscle area at 100 kg(L100)traits.Conclusions:The selected loci that we identified across methods displayed the past breeding process of Chinese Duroc pigs,and our findings could be used to inform future breeding decision.Zitao Chen Jinyan Teng Shuqi Diao Zhiting Xu Shaopan Ye Dingjie Qiu Zhe Zhang Yuchun Pan Jiaqi Li Qin Zhang Zhe Zhang 2023Journal of Animal Science and Biotechnology2023,14,1:0
13Structural Phase Transitions of Iodine at High Pressure显示文摘The compression and polymorphic phase transitions of iodine have been studied by using x-ray diffraction with a diamond anvil cell at high pressure up to 77GPa.Considering that iodine is reactive with iron in air,a corrosion-resisting and high-strength gasket was put between the diamonds,thus the sample can be mounted at atmospheric pressure and room temperature.Pressure was measured in terms of the ruby fluorescence and the molybdenum diffraction as an internal pressure standard.According to the x-ray diffraction results,the iodine undergoes the following three structural phase transitions with pressure increasing:(1)At 21 GPa,from base centred orthorhombic phase(phase Ⅰ)to body centred orthorhombic phase(phase Ⅱ).A 2%change in volume occurs.(2)At 44 GPa,from phase II to body centred tetragonal phase(phase Ⅲ).This is a second order phase transition.(3)At 71 GPa,from phase III to fcc phase(phase Ⅳ).The volume decreases by 3%.At this time,the volume is 45%of the original one at atmospheric pressure.CHEN Liangchen ZHANG Zhiting CHE Rongzheng YU Tingnan WANG Jifang 1994Chinese Physics Letters1994,11,2:0
14Mapping the emergence of visual consciousness in the human brain via brain-wide intracranial electrophysiology显示文摘Consciousness lies at the heart of our existence and experience.To probe how perceptual consciousness emerges in the brain,we recorded brainwide intracranial electroencephalography signals from human patients while their perceptual consciousness was effectively manipulated using the continuous flash suppression paradigm.We observed substantial differences in brain activities when visual information gradually enters consciousness.Liang Shan Hui Huang Zhiting Zhang Yuyin Wang Fei Gu Mingwei Lu Wen Zhou Yi Jiang Ji Dai 2022The Innovation2022,3,3:0
15Molecular biomarkers:multiple roles in radiotherapy显示文摘Preoperative chemoradiation therapy(CRT)is becoming the standard treatment for patients with locally advanced rectal cancer.However,individual differences in response to treatment range from a complete response to complete resistance.Predicting the tumor response to radiotherapy may improve the efficacy of radiotherapy.This review mainly summarizes recent studies about the molecular biomarkers that can predict the response to radiotherapy in rectal cancer.These studies have indicated that the molecular markers involved in the response to radiotherapy mainly include genes related to radiosensitivity,cancer stem cell-related markers,non-coding RNAs(ncRNAs),single-nucleotide polymorphisms(SNPs)and gene methylation,and other factors including carcinoembryonic antigen(CEA)level,anemia,lymphocytes,and signaling pathways.Many of these identified markers are mainly associated with DNA repair,apoptosis,and cell cycle,but some involve unknown cell mechanisms.We speculate that predictors of radiotherapy response may involve combinations of multiple molecular biomarkers that may be useful for the development of individualized therapy for rectal cancer patients.YUE CHEN ZHITING TANG MIAO YU RUI ZHANG XINXIN DONG LIANQUN CAO 2020BIOCELL2020,44,4:0

20Integrating genome-wide association study with multi-tissue transcriptome analysis provides insights into the genetic architecture of teat traits in pigs显示文摘Porcine teat numbers are crucial indicators of the reproductive performance of sows in the pig industry.During lactation periods,sows with fewer teats may lead to inadequate colostrum intake in piglets,which affects piglet weight gain and mortality(Tummaruk,2013).In pig breeding,high-intensity artificial selection on litter traits potentially gives rise to the functional weakening of teat traits due to the pleiotropic effects of genes affecting both traits(Chen et al.,2022).Chen Wei Xiaodian Cai Shuqi Diao Jinyan Teng Zhiting Xu Wenjing Zhang Haonan Zeng Zhanming Zhong Xibo Wu Yahui Gao Jiaqi Li Zhe Zhang 2023Journal of Genetics and Genomics2023,50,10:0
