1Controlled preparation of P-doped g-C3N4 nanosheets for efficient photocatalytic hydrogen production显示文摘Hydrogen production by photolysis of water by sunlight is an environmentally-friendly preparation technology for renewable energy.Graphitic carbon nitride(g-C3N4),despite with obvious catalytic effect,is still unsatisfactory for hydrogen production.In this work,phosphorus element is incorporated to tune g-C3N4's property through calcinating the mixture of g-C3N4 and Na H2PO2,sacrificial agent and co-catalyst also been supplied to help efficient photocatalytic hydrogen production.Phosphorus(P)doped g-C3N4 samples(PCN-S)were prepared,and their catalytic properties were studied.X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS),scanning electron microscopy(SEM)and ultraviolet diffuse reflection(UV-DRS)were used to study their structures and morphologies.The results show that the reaction rate of PCN-S is 318μmol·h^-1·g^-1,which is 2.98 times as high as pure carbon nitride nanosheets(CN)can do.Our study paves a new avenue,which is simple,environment-friendly and sustainable,to synthesize highly efficient P doping g-C3N4 nanosheets for solar energy conversion.Qiachun Lin Zesheng Li Tingjian Lin Bolin Li Xichun Liao Huiqing Yu Changlin Yu 2020Chinese Journal of Chemical Engineering2020,28,10:6
2Predictive cruise control for heavy trucks based on slope information under cloud control system显示文摘With the advantage of fast calculation and map resources on cloud control system(CCS), cloud-based predictive cruise control(CPCC) for heavy trucks has great potential to improve energy efficiency, which is significant to achieve the goal of national carbon neutrality. However, most investigations focus on the on-board predictive cruise control(PCC) system,lack of research on CPCC architecture under CCS. Besides, the current PCC algorithms have the problems of a single control target and high computational complexity, which hinders the improvement of the control effect. In this paper, a layered architecture based on CCS is proposed to effectively address the realtime computing of CPCC system and the deployment of its algorithm on vehicle-cloud. In addition, based on the dynamic programming principle and the proposed road point segmentation method(RPSM), a PCC algorithm is designed to optimize the speed and gear of heavy trucks with slope information. Simulation results show that the CPCC system can adaptively control vehicle driving through the slope prediction, with fuel-saving rate of 6.17% in comparison with the constant cruise control. Also,compared with other similar algorithms, the PCC algorithm can make the engine operate more in the efficient zone by cooperatively optimizing the gear and speed. Moreover, the RPSM algorithm can reconfigure the road in advance, with a 91% roadpoint reduction rate, significantly reducing algorithm complexity.Therefore, this study has essential research significance for the economic driving of heavy trucks and the promotion of the CPCC system.LI Shuyan WAN Keke GAO Bolin LI Rui WANG Yue LI Keqiang 2022Journal of Systems Engineering and Electronics2022,33,4:5
3Disease gene identification by using graph kernels and Markov random fields显示文摘Genes associated with similar diseases are often functionally related.This principle is largely supported by many biological data sources,such as disease phenotype similarities,protein complexes,protein-protein interactions,pathways and gene expression profiles.Integrating multiple types of biological data is an effective method to identify disease genes for many genetic diseases.To capture the gene-disease associations based on biological networks,a kernel-based Markov random field(MRF)method is proposed by combining graph kernels and the MRF method.In the proposed method,three kinds of kernels are employed to describe the overall relationships of vertices in five biological networks,respectively,and a novel weighted MRF method is developed to integrate those data.In addition,an improved Gibbs sampling procedure and a novel parameter estimation method are proposed to generate predictions from the kernel-based MRF method.Numerical experiments are carried out by integrating known gene-disease associations,protein complexes,protein-protein interactions,pathways and gene expression profiles.The proposed kernel-based MRF method is evaluated by the leave-one-out cross validation paradigm,achieving an AUC score of 0.771 when integrating all those biological data in our experiments,which indicates that our proposed method is very promising compared with many existing methods.CHEN BoLin LI Min WANG JianXin WU FangXiang 2014Science China(Life Sciences)2014,57,11:5

5Preparation of N-Doped Bi_2WO_6 Microspheres for Efficient Visible Light-Induced Photocatalysis显示文摘The N-doped bismuth tungstate(Bi_2WO_6) photocatalysts with high visible light activity were prepared by the hydrothermal method using urea as a nitrogen source.The as-prepared N-doped Bi_2WO_6 samples were characterized by X-ray diffraction,scanning electron microscopy,specific surface area,photocurrent analysis,and UV-Vis diffuse reflectrance spectroscopy.The photocatalytic activity was evaluated by photocatalytic degradation of rhodamine B(RhB)solution under visible light irradiation.The photocatalytic mechanisms were analyzed by active species trapping experiments which revealed that the holes were the main active species of N-doped Bi_2WO_6 products in aqueous solution under visible light irradiation,rather than OH and O_2^-.With the assistance of H_2O_2,the photocatalytic activity for degradation of RhB could be further improved because H_2O_2 reacted with conduction band electrons to generate more hydroxyl radicals.Bolin Tang Guohua Jiang Zhen Wei Xia Li Xiaohong Wang Tengteng Jiang Wenxing Chen Junmin Wan 2014Acta Metallurgica Sinica(English Letters)2014,27,1:4
6Female Plant Types of Ginkgo biloba L. in China显示文摘Ginkgo biloba is a dioecious and unique species within Ginkgo family and Ginkgo genus, but it shows a big variability. From 1950s, resources of female plants in China were investigated and collected, and the seed anatomical structure and morphological characters at different development stages were observed. According to the shape, length, width and thickness of ovule bracket and seed stone, as well as the characteristics of both sides and top of the stone, the female plants of Ginkgo biloba have been divided into five types, long-stone, Buddha-finger, horse-bell, mume-stone and round-stone. In addition, the important cultivars belonging to different types were also determined. The stone weight, index of stone shape, and contents of dry matter, amylose, amylopectin, starch, rough protein, soluble sugar and hydrocyanic acid in seed kernel of each type were measured, and the qualities of seed stone were appraised, which lays a foundation for the improvement and utilization of female plant resources in Ginkgo biloba.Chen Peng He Fengren Tao Jun Qian Bolin Wei Jun Ling Yuping Wang Li Department of Horticulture, Agricultural College Yangzhou University, Yangzhou 225009, P.R.China 2003Forestry Studies in China2003,5,2:4

8Image processing operations identification via convolutional neural network显示文摘Dear editor,In recent years,image forensics has attracted increasing attention,and many forensic methods have been proposed for identifying image processing operations.Until now,most existing methods have been based on hand-crafted features,and only one specific operation is considered in these methods.In many forensic scenarios,however,multiple classification for various image processing operations is more practical.In addition,for some image processing operations,it is difficult to construct effective hand-crafted features.In this study,we therefore propose a new method based on convolutional neural networks(CNNs)to adaptively learn discriminative features for identifying typical image processing operations.However,directly employ CNN structures in other fields(e.g.,computer vision)for image forensics cannot obtain satisfactory performance.Thus,we carefully design the network structures(including the highpass filter bank,the channel expansion layer,the pooling layers,and the activation functions)of the proposed method.Experimental results show that the proposed method outperforms the current best method,which is based on hand-crafted features,and three related methods based on CNNs for image steganalysis and/or forensics,achieving stateof-the-art results.Furthermore,we provide supplementary results to show the rationality and robustness of the proposed model.Bolin CHEN Haodong LI Weiqi LUO Jiwu HUANG 2020Science China(Information Sciences)2020,63,3:3
9Genome sequencing and phylogenetic analysis of allotetraploid Salix matsudana Koidz显示文摘Polyploidy is a common phenomenon among willow species.In this study,genome sequencing was conducted for Salix matsudana Koidz(also named Chinese willow),an important greening and arbor tree species,and the genome of this species was compared with those of four other tree species in Salicaceae.The total genome sequence of S.matsudana was 655.72 Mb in size,with repeated sequences accounting for 45.97%of the total length.In total,531.43 Mb of the genome sequence could be mapped onto 38 chromosomes using the published genetic map as a reference.The genome of S.matsudana could be divided into two groups,the A and B genomes,through homology analysis with the genome of Populus trichocarpa,and the A and B genomes contained 23,985 and 25,107 genes,respectively.4DTv combined transposon analysis predicted that allotetraploidy in S.matsudana appeared~4 million years ago.The results from this study will help reveal the evolutionary history of S.matsudana and lay a genetic basis for its breeding.Jian Zhang Huwei Yuan Yujuan Li Yanhong Chen Guoyuan Liu Meixia Ye Chunmei Yu Bolin Lian Fei Zhong Yuna Jiang Jichen Xu 2020Horticulture Research2020,7,1:3

12Preventing and Limiting Exposure to Geo-Hazards:Some Lessons from Two Mountain Villages Destroyed by the Wenchuan Earthquake显示文摘This paper examines the experiences of two mountain communities- Yinchanggou and Donghekou in the Wenchuan earthquake of May 12, 2008, where Yinchanggou's tourism economy and natural park system was destroyed and Donghekou was buried by a landslide. We conducted research surveys on both the communities, interviewing survivors and local officials, and observed the destruction/reconstruction, geological, and living conditions. We suggest that protracted educational processes be put into place so that mountain communities possess a knowledge base to consider long-term disaster prevention when building the economy in the fragile and geo-hazardous conditions of the Longmenshan. The Donghekou Earthquake Ruins Park is an exemplar of turning disaster into sustainable, safe development for small mountain villages.Laurence SVIRCHEV LI Yong YAN Liang MA Bolin HE Chengying 2011Journal of Mountain Science2011,8,2:2
13A Cost-Effective D-A-D Type Hole-Transport Material Enabling 20% Efficiency Inverted Perovskite Solar Celis显示文摘High-performance,cost-effective hole-transport materials(HTMs)are greatly desired for the commercialization of perovskite solar cells(PVSCs).Herein,two new HTMs,TPA-FO and TPA-PDO,are devised and synthesized,which have a donor-acceptor-donor(D-A-D)type molecule design featuring carbonyl group-functionalized arenes as the acceptor(A)units.The carbonyl group at the central core of HTMs can not only tune frontier molecular orbital(FMO)energy levels and surface wettability,but also can enable efficient surface passivation effects,resulting in reduced recombination loss.When employed as HTMs in inverted PVSCs without using dopant,TPA-FO with one carbonyl group yields a high power conversion efficiency(PCE)of 20.24%,which is among the highest values reported in the inverted PVSCs with dopant-free HTMs.More importantly,the facile one-step synthetic process enables a low cost of 30 USD g^(-1) for TPA-FO,much cheaper than the most studied HTMs used for high-efficiency dopant-free PVSCs.These results demonstrate the potential of D-A-D type molecules with carbonyl group-functionalized arene core in developing the low-cost dopant-free HTMs toward highly efficient PVSCs.Jiachen Huang Jie Yang Huiliang Sun Kui Feng Qiaogan Liao Bolin Li He Yan Xugang Guo 2021Chinese Journal of Chemistry2021,39,6:2
14Passivation of degradation path enables high performance perovskite nanoplatelet lasers with high operational stability显示文摘MAPbI_(3)perovskite has attracted widespread interests for developing low-cost near infrared semiconductor gain media.However,it faces the instability issue under operation conditions,which remains a critical challenge.It is found that the instability of the MAPbI_(3)nanoplatelet laser comes from the thermal-induced degradation progressing from the surface defects towards neighboring regions.By using PbI_(2) passivation,the defect-initiated degradation is significantly suppressed and the nanoplatelet degrades in a layer-by-layer way,enabling the MAPbI_(3)laser to sustain for 4500 s(2.7×10^(7) pulses),which is nearly three times longer than that of the nanoplatelet laser without passivation.Meanwhile,the PbI_(2) passivated MAPbI_(3)nanoplatelet laser with the nanoplatelet cavity displays a maximum quality factor up to∼7800,the highest reported for all MAPbI_(3)nanoplatelet cavities.Furthermore,a high stability MAPbI_(3)nanoplatelet laser that can last for 8500 s(5.1×10^(7) pulses)is demonstrated based on a dual passivation strategy,by retarding the defect-initiated degradation and surface-initiated degradation simultaneously.This work provides in-depth insights for understanding the operating degradation of perovskite lasers,and the dual passivation strategy paves the way for developing high stability near infrared semiconductor laser media.GUOHUI LI HUIHUI PI YANFU WEI BOLIN ZHOU YA GAO RONG WEN YUYING HAO HAN ZHANG BENG S.ONG YANXIA CUI 2022Photonics Research2022,10,6:2

18Several miRNAs derived from serum extracellular vesicles are potential biomarkers for early diagnosis and progression of Parkinson’s disease显示文摘Background:Blood-based test for predicting disease progression and early diagnosis of Parkinson’s disease(PD)is an unmet need in the clinic.The profiles of microRNAs(miRNAs)are regarded as potential diagnostic biomarkers for human diseases,whereas miRNAs in the periphery are susceptible to the influence of various components.MiRNAs enriched in serum extracellular vesicles(EVs)have demonstrated disease-specific advantages in diagnosis due to their high abundance,stability and resistance to degradation.This study was aimed to screen differentially expressed EV-derived miRNAs between healthy controls and PD patients to aid in diagnosis of PD.Methods:A total of 31 healthy controls and 72 patients with a diagnosis of PD at different Hoehn and Yahr stages in Tangdu Hospital were included.In total,185 differentially expressed miRNAs were obtained through RNA sequencing of serum EVs as well as edgeR and t-test analyses.Subsequently,the weighted gene co-expression network analysis(WGCNA)was utilized to identify the commonly expressed miRNAs in all stages of PD by constructing connections between modules,and specifically expressed miRNAs in each stage of PD by functional enrichment analysis.After aligning these miRNAs with PD-related miRNAs in Human miRNA Disease Database,the screened miRNAs were further validated by receiver operating characteristic(ROC)curves and quantitative real-time polymerase chain reaction(qRT-PCR)using peripheral blood EVs from 40 more participants.Results:WGCNA showed that 4 miRNAs were commonly associated with all stages of PD and 13 miRNAs were specifically associated with different stages of PD.Of the 17 obtained miRNAs,7 were validated by ROC curve analysis and 7 were verified in 40 more participants by qRT-PCR.Six miRNAs were verified by both methods,which included 2 miRNAs that were commonly expressed in all stages of PD and 4 miRNAs that were specifically expressed in different stages of PD.Conclusions:The 6 serum EV-derived miRNAs,hsa-miR-374a-5p,hsa-miR-374b-5p,hsa-miR-199a-3p,hsa-miR-28-5p,hsa-miR-22-5p and hsa-miR-151a-5p,may potentially be used as biomarkers for PD progression and for early diagnosis of PD in populations.Shulei He Lu Huang Ci Shao Tiejian Nie Li Xia Bozhou Cui Fangfang Lu Lin Zhu Bolin Chen Qian Yang 2021Translational Neurodegeneration2021,10,3:1
