| 1 | Antiviral adsorption activity of porous silicon nanoparticles against different pathogenic human viruses显示文摘New viral infections,due to their rapid spread,lack of effective antiviral drugs and vaccines,kill millions of people every year.The global pandemic SARS-CoV-2 in 2019-2021 has shown that new strains of viruses can widespread very quickly,causing disease and death,with significant socio-economic consequences.Therefore,the search for new methods of combating different pathogenic viruses is an urgent task,and strategies based on nanoparticles are of significant interest.This work demonstrates the antiviral adsorption(virucidal)efficacy of nanoparticles of porous silicon(PSi NPs)against various enveloped and non-enveloped pathogenic human viruses,such as Influenza A virus,Poliovirus,Human immunodeficiency virus,West Nile virus,and Hepatitis virus.PSi NPs sized 60 nm with the average pore diameter of 2 nm and specific surface area of 200 m^(2)/g were obtained by ball-milling of electrochemically-etched microporous silicon films.After interaction with PSi NPs,a strong suppression of the infectious activity of the virus-contaminated fluid was observed,which was manifested in a decrease in the infectious titer of all studied types of viruses by approximately 104 times,and corresponded to an inactivation of 99.99%viruses in vitro.This sorption capacity of PSi NPs is possible due to their microporous structure and huge specific surface area,which ensures efficient capture of virions,as confirmed by ELISA analysis,dynamic light scattering measurements and transmission electron microscopy images.The results obtained indicate the great potential of using PSi NPs as universal viral sorbents and disinfectants for the detection and treatment of viral diseases. | Liubov A.Osminkina Svetlana N.Agafilushkina Ekaterina A.Kropotkina Nikolay Yu Saushkin Ivan V.Bozhev Sergei S.Abramchuk Jeanne V.Samsonova Alexandra S.Gambaryan | 2022 | Bioactive Materials2022，7，1： | 1 |

| 7 | Hole-doping of mechanically exfoliated graphene by confined hydration layers显示文摘By the use of non-contact atomic force microscopy (NC-AFM) and Kelvin probe force microscopy (KPFM), we measure the local surface potential of mechanically exfoliated graphene on the prototypical insulating hydrophilic substrate of CAF2(111). Hydration layers confined between the graphene and the CaF2 substrate, resulting from the graphene's preparation under ambient conditions on the hydrophilic substrate surface, are found to electronically modify the graphene as the material's electron density transfers from graphene to the hydration layer. Density functional theory (DFT) calculations predict that the first 2 to 3 water layers adjacent to the graphene hole-dope the graphene by several percent of a unit charge per unit cell. | Tjeerd R.

| 12 | High yield production of ultrathin fibroid semiconducting nanowire of Ta2Pd3Se8显示文摘Immediately after the demonstration of the high-quality electronic properties in various two dimensional(2D)van der Waals(vdW)crystals fabricated with mechanical exfoliation,many methods have been reported to explore and control large scale fabrications.Comparing with recent advancements in fabricating 2D atomic layered crystals,large scale production of one dimensional(1D)nanowires with thickness approaching molecular or atomic level still remains stagnant.Here,we demonstrate the high yield production of a 1D vdW material,semiconducting Ta2Pd3Se8 nanowires,by means of liquid-phase exfoliation.The thinnest nanowire we have readily achieved is around 1 nm,corresponding to a bundle of one or two molecular ribbons.Transmission electron microscopy(TEM)and transport measurements reveal the as-fabricated Ta2Pd3Se8 nanowires exhibit unexpected high crystallinity and chemical stability.Our low-frequency Raman spectroscopy reveals clear evidence of the existing of weak inter-ribbon bindings.The fabricated nanowire transistors exhibit high switching performance and promising applications for photodetectors. | Xue Liu Sheng Liu Liubov Yu.Antipina Yibo Zhu Jinliang Ning Jinyu Liu Chunlei Yue Abin Joshy Yu Zhu Jianwei Sun Ana M.Sanchez Pavel B.Sorokin Zhiqiang Mao Qihua Xiong Jiang Wei | 2020 | Nano Research2020，13，6： | 0 |

| 14 | Magnetic force microscopy of an operational spin nano-oscillator显示文摘Magnetic force microscopy(MFM)is a powerful technique for studying magnetic microstructures and nanostructures that relies on force detection by a cantilever with a magnetic tip.The detected magnetic tip interactions are used to reconstruct the magnetic structure of the sample surface.Here,we demonstrate a new method using MFM for probing the spatial profle of an operational nanoscale spintronic device,the spin Hall nano-osillator(SHNO),which generates high-intensity spin wave auto-osillations enabling novel microwave applications in magnonics and neuromorphic computing.We developed an MFM system by adding a microwave probe station to allow electrical and microwave characterization up to 40 GHz during the MFM process.SHNOs-based on NiFe/Pt bilayers with a specific design compatible with the developed system-were fabricated and scanned using a Co magnetic force microscopy tip with 10 nm spatial MFM resolution,while a DC current sufficient to induce auto-oscillation flowed.Our results show that this developed method provides a promising path for the characterization and nanoscale magnetic field imaging of operational nano-osilators. | Seyed Amir Hossein Banuazizi Afshin Houshang Ahmad A Awad Javad Mohammadi Johan Akerman Liubov M.Belova | 2022 | Microsystems & Nanoengineering2022，8，3： | 0 |
| 15 | Using Bayesian multitemporal classification to monitor tropical forest cover changes in Kalimantan,Indonesia显示文摘Significant areas of native forest in Kalimantan,on the island of Borneo,have been cleared for the expansion of plantations of oil palm and rubber.In this study multisource remote sensing was used to develop a time series of land cover maps that distinguish native forest from plantations.Using a study area in east Kalimantan,Landsat images were combined with either ALOS PALSAR or Sentinel-1 images to map four land cover classes(native forest,oil palm plantation,rubber plantation,non-forest).Bayesian multitemporal classification was applied to increase map accuracy and maps were validated using a confusion matrix;final map overall accuracy was>90%.Over 18 years from 2000 to 2018 nearly half the native forests in the study area were converted to either non-forest or plantations of either rubber or oil palm,with the highest losses between 2015 and 2016.Trending upwards from 2008 large areas of degraded or cleared forests,mapped as non-forest,were converted to oil palm plantation.Conversion of native forests to plantation mainly occurred in lowland and wetland forest,while significant forest regrowth was detected in degraded peatland.These maps will help Indonesia with strategies and policies for balancing economic growth and conservation. | Inggit Lolita Sari Christopher J.Weston Glenn J.Newnham Liubov Volkova | 2022 | International Journal of Digital Earth2022，15，1： | 0 |
| 16 | 桉树树干维管形成层和次生韧皮部热致细胞坏死的定量试验显示文摘桉树(Eucalyptus)树干暴露在森林火灾辐射热中会杀死形成层细胞及其内嵌的再生分生组织,阻止树木萌枝和恢复。目前尚无组织水平的方法来量化热处理对桉树形成层细胞活力的影响。本研究的目标包括:(1)采用并验证四氮唑还原法检测桉树细胞活力;(2)应用该方法确定斜叶桉(Eucalyptus oblique)形成层细胞活力的阈值水平,进而确定临界温度。采用四氮唑还原法量化该桉树韧皮部-形成层细胞活力。从斜叶桉成树上切下带有形成层和韧皮部的圆形树皮切片,将质量为1-30 mg不等的样品在20-85℃的温度处理中放置1分钟,并在室温条件下在0.8%的2,3,5-氯化三苯基四氮唑(TTC)中保存20-22小时以检测细胞活力。用乙醇冷萃取得到1,3,5-三苯基四唑甲臜(TPF),在485nm处测定吸光度。结果表明,TTC还原法准确地量化了组织切片(包括维管形成层)中细胞活力随温度升高而下降的情况,并确定60℃为枝树物种形成层-韧皮部细胞的临界温度。细胞活力按[TPF处理温度]/[TPF20℃]计算,在20-85℃之间下降90%.细胞活力结果证实,在50-70℃的温度区间,经过1分钟体外组织加热,桉树的组织坏死显著增加。TTC方法显示细胞活力随温度升高而下降,这与温度处理和中性红染色处理后独立获得的活细胞计数一致。 | Yasika Medhavi Subasinghe Achchige Liubov Volkova Andrew Drinnan Christopher J.Weston | 2021 | Journal of Plant Ecology2021，14，1： | 0 |
| 17 | Reversible hydrogenation restores defected graphene to graphene显示文摘Graphene as a two-dimensional material is prone to hydrocarbon contaminations,which can significantly alter its intrinsic electrical properties.Herein,we implement a facile hydrogenation-dehydrogenation strategy to remove hydrocarbon contaminations and preserve the excellent transport properties of monolayer graphene.Using electron microscopy we quantitatively characterized the improved cleanness of hydrogenated graphene compared to untreated samples.In situ spectroscopic investigations revealed that the hydrogenation treatment promoted the adsorption of water at the graphene surface,resulting in a protective layer against the re-deposition of hydrocarbon molecules.Additionally,the further dehydrogenation of hydrogenated graphene rendered a more pristine-like basal plane with improved carrier mobility compared to untreated pristine graphene.Our findings provide a practical post-growth cleaning protocol for graphene with maintained surface cleanness and lattice integrity to systematically carry a range of surface chemistry in the form of a well-performing and reproducible transistor. | Lin Jiang Pauline MGvan Deursen Hadi Arjmandi-Tash Liubov ABelyaeva Haoyuan Qi Jiao He Vincent Kofman Longfei Wu Valery Muravev Ute Kaiser Harold Linnartz Emiel JMHensen Jan PHofmann Grégory FSchneider | 2021 | Science China Chemistry2021，64，6： | 0 |

| 20 | Additive predictions of aboveground stand biomass in commercial logs and harvest residues for rotation age Pinus radiata plantations in New South Wales,Australia显示文摘Two systems of additive equations were developed to predict aboveground stand level biomass in log products and harvest residue from routinely measured or predicted stand variables for Pinus radiata plantations in New South Wales,Australia.These plantations were managed under three thinning regimes or stand types before clear-felling at rotation age by cut-to-length harvesters to produce sawlogs and pulpwood.The residue material following a clear-fell operation mainly consisted of stumps,branches and treetops,short off-cut and waste sections due to stem deformity,defects,damage and breakage.One system of equations did not include dummy variables for stand types in the model specification and was intended for more general use in plantations where stand density management regimes were not the same as the stand types in our study.The other system that incorporated dummy variables was for stand type-specific applications.Both systems of equations were estimated using 61 plot-based estimates of biomass in commercial logs and residue components that were derived from systems of equations developed in situ for predicting the product and residue biomass of individual trees.To cater for all practical applications,two sets of parameters were estimated for each system of equations for predicting component and total aboveground stand biomass in fresh and dry weight respectively.The two sets of parameters for the system of equations without dummy variables were jointly estimated to improve statistical efficiency in parameter estimation.The predictive performances of the two systems of equations were benchmarked through a leave-one-plot-out cross validation procedure.They were generally superior to the performance of an alternative two-stage approach that combined an additive system for major components with an allocative system for sub-components.As using forest harvest residue biomass for bioenergy has increasingly become an integrated part of forestry,reliable estimates of product and residue biomass will assist harvest and management planning for clear-fell operations that integrate cut-to-length log production with residue harvesting. | Xixi Qiao Huiquan Bi Yun Li Fabiano Ximenes Christopher JWeston Liubov Volkova Mohammad Reza Ghaffariyan | 2021 | Journal of Forestry Research2021，32，6： | 0 |
