| 1 | 水热亚硫酸预处理菊芋秸秆的高浓底物酶水解试验显示文摘为了有效改善菊芋秸秆用于乙醇转化过程中的酶水解糖化性能,对经水热H2SO3预处理的秸秆进行高浓底物酶水解试验,研究了适合的预处理条件及其底物质量分数提高潜力以及酶使用量缩减潜力。结果显示:在180℃条件下,添加2.0%的H2SO3进行水热预处理后的菊芋秸秆,其组分中的半纤维素可被完全去除。并且在底物质量分数为2.0%、纤维素酶和纤维二糖酶使用量分别为20FPU/g和40CBU/g条件下,获得90.0%的最大酶水解率。在此条件下预处理后的菊芋秸秆,酶水解的底物质量分数可提高的潜力为12%。在此底物质量分数下进行酶水解,纤维素酶使用量可缩减为15FPU/g,纤维二糖酶使用量可缩减至20CBU/g。在此酶使用量条件下,虽然纤维素酶和纤维二糖酶分别减少了25%和50%,酶水解率仍可达88.3%。相比最大水解率,仅降低1.8%。 | 沈飞 王卿 李阳 李秀金 Hu Jinguang | 2014 | 农业机械学报2014,45,3: | 4 |
| 2 | Creep-Induced Phase Instability and Microstructure Evolution of a Nearly Lamellar Ti–45Al–8.5Nb–(W, B, Y) Alloy显示文摘Microstructure degradation and stress-induced transformation of a high Nb-containing TiAl alloy with nearly lamellar microstructure during creep were investigated.Tensile creep experiments were performed at 800,850 and 900℃ under 150 MPa in air.Microstructures before and after creep tests were examined using scanning and transmission electron microscopy(SEM and TEM).Dislocations within the lamellar structure andβo(ω)region and twin intersection in massiveγgrains were investigated.Dislocation sliding played a critical role in the deformation ofωo phase,which preferentially occurred on the(0002)ωo plane.Possible deformation mechanisms were revealed.A stress-inducedγ→α2 phase transformation took place during the creep test at 850 and 900℃.α2 lamella could directly decompose into theωo phase at 850℃.The instability of high-temperature microstructure can weaken the creep resistance and promote the plastic deformation of the lamellar matrix,thus could be detrimental to the creep properties.The correlations between creep properties and microstructure instability were discussed. | Xuyang Wang Jieren Yang Rui Hu Zitong Gao Jinguang Li Hengzhi Fu | 2020 | Acta Metallurgica Sinica(English Letters)2020,33,12: | 3 |
| 3 | Tailoring biochar by PHP towards the oxygenated functional groups(OFGs)-rich surface to improve adsorption performance显示文摘In this work,a modification method of H_(3)PO_(4)plus H_(2)O_(2)(PHP)was introduced to targetedly form abundant oxygenated functional groups(OFGs)on biochar,and methylene blue(MB)was employed as a model pollutant for adsorption to reflect the modification performance.Results indicated that parent biochars,especially derived from lower temperatures,substantially underwent oxidative modification by PHP,and OFGs were targetedly produced.Correspondingly,approximately 21.5-fold MB adsorption capacity was achieved by PHP-modified biochar comparing with its parent biochar.To evaluate the compatibility of PHP-modification,coefficient of variation(CV)based on MB adsorption capacity by the biochar from various precursors was calculated,in which the CV of PHP-modified biochars was 0.0038 comparing to0.64 of the corresponding parent biochars.These results suggested that the PHP method displayed the excellent feedstock compatibility on biochar modification.The maximum MB adsorption capacity was454.1 mg/g when the H_(3)PO_(4)and H_(2)O_(2)fraction in PHP were 65.2%and 7.0%;the modification was further intensified by promoting temperature and duration.Besides,average 94.5%H_(3)PO_(4)was recovered after 10-batch modification,implying 1.0 kg H_(3)PO_(4)(85%)in PHP can maximally modify 2.37 kg biochar.Overall,this work offered a novel method to tailor biochar towards OFGs-rich surface for efficient adsorption. | Xinyue Xiong Zhanglin Liu Li Zhao Mei Huang Lichun Dai Dong Tian Jianmei Zou Yongmei Zeng Jinguang Hu Fei Shen | 2022 | Chinese Chemical Letters2022,33,6: | 1 |

| 5 | Carbon quantum dots modified TiO_(2) composites for hydrogen production and selective glucose photoreforming显示文摘Lignocellulosic biomass photoreforming is a promising and alternative strategy for both sustainable H_(2) production and biomass valorization with infinite solar energy.However,harsh reaction conditions(high alkalinity or toxic organic solvents),with low biomass conversion and selectivity are often reported in literature.In this work,we report glucose photoreforming for coproduction of H_(2) and arabinose with improved selectivity under neutral condition using carbon quantum dots(CQDs)modified TiO_(2) composites.We show that the conventional CQDs fabricated by a facile one-step hydrothermal process could be endowed with novel color changing property,due to the particle aggregation under the regulation of incident light.The as-fabricated CQDs/TiO_(2) composites with certain colored CQDs could greatly improve glucose to arabinose conversion selectivity(-75%)together with efficient hydrogen evolution(up to 2.43 mmolh^(-1)g^(-1))in water.The arabinose is produced via the direct C1-C2 α-scissions mechanism with reactive oxygen species of·O_(2)^(-) and·OH,as evidenced by ^(13)C labeled glucose and the electron spin-resonance(ESR)studies,respectively.This work not only sheds new lights on CQDs assisted photobiorefinery for biomass valorization and H_(2) coproduction,but also opens the door for rationale design of different colored CQDs and their potential applications for solar energy utilization in the noble-metal-free system. | Heng Zhao Xinti Yu Chao-Fan Li Wenbei Yu Aiguo Wang Zhi-Yi Hu Steve Larter Yu Li Md Golam Kibria Jinguang Hu | 2022 | Journal of Energy Chemistry2022,31,1: | 1 |

| 7 | Dual-functional marigold-like Zn_(x)Cd_(1-x)S homojunction for selective glucose photoreforming with remarkable H_(2)coproduction显示文摘The global commitment to pivoting to sustainable energy and products calls for technology development to utilize solar energy for hydrogen(H_(2))and value-added chemicals production by biomass photoreforming.Herein,a novel dual-functional marigold-like Zn_(x)Cd_(1-x)S homojunction has been the production of lactic acid with high-yield and H_(2)with high-efficiency by selective glucose photoreforming.The optimized Zn_(0.3)Cd_(0.7)S exhibits outstanding H_(2)generation(13.64 mmol h^(-1)g^(-1)),glucose conversion(96.40%),and lactic acid yield(76.80%),over 272.80 and 19.21 times higher than that of bare ZnS(0.05 mmol h^(-1)g^(-1))and CdS(0.71 mmol h^(-1)g^(-1))in H_(2)generation,respectively.The marigold-like morphology provides abundant active sites and sufficient substrates accessibility for the photocatalyst,while the specific role of the homojunction formed by hexagonal wurtzite(WZ)and cubic zinc blende(ZB)in photoreforming biomass has been demonstrated by density functional theory(DFT)calculations.Glucose is converted to lactic acid on the WZ surface of Zn_(0.3)Cd_(0.7)S via the photoactive species·O_(2)^(-),while the H_(2)is evolved from protons(H^(+))in H_(2)O on the ZB surface of Zn_(0.3)Cd_(0.7)S.This work paves a promising road for the production of sustainable energy and products by integrating photocatalysis and biorefine. | Fuyan Kang Cai Shi Yeling Zhu Malin Eqi Junming Shi Min Teng Zhanhua Huang Chuanling Si Feng Jiang Jinguang Hu | 2023 | Journal of Energy Chemistry2023,,4: | 1 |
| 8 | Selective superoxide radical generation for glucose photoreforming into arabinose显示文摘Biomass photorefinery to produce fuels and valuable chemicals is a promising approach to alleviating the energy crisis and achieving carbon neutrality.However,precisely modulating the photocatalytic conversion of biomass into value-added chemicals is still challenging.Here we demonstrate a feasible strategy to selectively produce arabinose via oriented glucose oxidation to gluconic acid,followed by the decarboxylation process for C1-C2 bond cleavage.To realize this process,gold nanoparticles(Au NPs)modified carbon nitride(AuCN)is rationally designed to regulate the electron transfer behavior of pristine carbon nitride from a two-electron pathway to a single-electron pathway.This allows selective production of superoxide(·O_(2)^(-))from oxygen reduction reaction which triggers glucose oxidation into gluconic acid.In addition,the arabinose production is synergistically promoted by the improved charge separation efficiency and extended visible-light absorption via localized surface plasmon resonance(LSPR)of Au nanoparticles.This work demonstrates an example of a mechanism-guided catalyst design to improve biofuels/chemicals production from biomass photorefinery. | Jiu Wang Heng Zhao Peng Liu Nael Yasri Na Zhong Md Golam Kibria Jinguang Hu | 2022 | Journal of Energy Chemistry2022,31,11: | 1 |

| 10 | The development and application of an inviscid inverse method显示文摘A two-dimensional inviscid inverse method is developed,verified and applied inthis paper.The method solves the Euler equation in absolute reference frame by a cell-centeredfinite volume method,and the hybrid Runge-Kutta method ls used for time integration.Different from the direct method,the inverse method imposes a unique'transpiration'boundary condition on the blade surfaces.The inputs of inverse method are pressure loadingand blade tangential thickness distribution along the blade chord.During the time marchingprocess,the blade shape is periodically updated.When the solution is converged,the bladeshape will be stabled.In the paper,the principle of the inverse method is described in detail.Then the developed inverse method is verified against a consistence test:recover an axialcompressor cascade from a different start.Finally,to demonstrate the powerful capability ofthe method,it is used to redesign the cascade,and final results give an improved aerodynamicperformance. | Jinguang Yang Hu Wu | 2013 | Propulsion and Power Research2013,2,2: | 1 |
| 11 | Control Effect and Cost Evaluation of Different Sex Pheromones and Trapping Lamps against Spodoptern litura,Helicoverpa assulta and Helicoverpa armigera in Tobacco显示文摘[Objective]The aim was to study the control effect of different sex pheromones and trapping lamps against main pests in tobacco. [Method]Control effect of sex pheromone of different matrix lures and Jiaduo trapping lamp against Spodoptern litura,Helicoverpa assulta and Helicoverpa armigera in tobacco in Tengchong of Yunnan were determined and compared,and the control cost was evaluated. [Result] The use of insect sex pheromones and insecticidal light traps had certain effect against S. litura and H. armiger. The trapping effect of sex pheromone traps was better than that of Jiaduo trapping lamp,and the PVC matrix lure had better performance than rubber matrix lure,which had strongest capturing capacity,continuous control effect and significant effort against S. litura. The traps with different settled densities and hanging heights also had different trapping effect against S. litura and H. armiger,and the hanging height of 100 - 150 cm from ground was the best; as the cost was considered,the cost of the area with low density of traps was the lowest,which was reduced by over 44% than conventional chemical control area. [Conclusion]It is safe and effective to use sex pheromone and insecticidal light traps to control S. litura and H. armigera,and it is a green environmental protection biological physical control technology,having extended application prospect in large area. | Yongliang LI Li LI Zhiming HU Xingdong YANG Yanping DUAN Jinguang YANG | 2012 | Plant Diseases and Pests2012,3,3: | 1 |
| 12 | High-timing-precision detection of single X-ray photons by superconducting nanowires显示文摘Precisely acquiring the timing information of individual X-ray photons is important in both fundamental research and practical applications. The timing precision of commonly used X-ray single-photon detectors remains in the range of one hundred picoseconds to microseconds. In this work, we report on high-timing-precision detection of single X-ray photons through the fast transition to the normal state from the superconductive state of superconducting nanowires. We successfully demonstrate a free-running X-ray single-photon detector with a timing resolution of 20.1 ps made of 100-nm-thick niobium nitride film with an active area of 50 μm by 50 μm. By using a repeated differential timing measurement on two adjacent X-ray single-photon detectors, we demonstrate a precision of 0.87 ps in the arrival-time difference of X-ray photon measurements. Therefore, our work significantly enhances the timing precision in X-ray photon counting, opening a new niche for ultrafast X-ray photonics and many associated applications. | Shuya Guo Jingrou Tan Hengbin Zhang Jinguang Wang Tianhao Ji Labao Zhang Xiaolong Hu Jian Chen Jun Xie Kai Zou Yun Meng Xiaomin Bei Ling-An Wu Qi Chen Hao Wang Xuecou Tu Xiaoqing Jia Qing-Yuan Zhao Lin Kang Peiheng Wu | 2024 | National Science Review2024,11,1: | 0 |

| 14 | Super-anti-freezing,tough and adhesive titanium carbide and L-ornithine-enhanced hydrogels显示文摘Hydrogels are highly porous three-dimensional crosslinked polymer networks consisting of hy-drophilic polymers,employed most practically in medicine and industry,often as biosensors.Simple hydrogels suffer limitations in their mechanical properties,such as tensile and com-pression,and freeze at sub-zero temperatures,which compromise their ability as useful biosen-sors.In this study,the incorporation of L-ornithine-based zwitterionic monomer(OZM),titanium carbide(MXene),and glycerol within polyacrylamide hydrogels was used to prepare a novel polyacrylamide/polyL-ornithine-based zwitterion/MXene(PAM/Porn/MXene)hydrogel to im-prove the mechanical,adhesion,and anti-freezing properties of pure polyacrylamide hydrogels.This study also analyzed the mechanical strength(tensile and compression),adhesion,and anti-freezing properties of a novel PAM/Porn/MXene hydrogel at 1%,4%,and 10%MXene concen-trations to establish to what extent the conductive MXene material enhanced these properties and concluded that the tensile and compressive properties improved linearly with the increase in the concentrations of MXene,adhesion decreased with the increased MXene concentrations,and syn-ergistic interaction between MXene and OZM significantly improved the anti-freezing properties up to-80°C. | Zhangkang Li Jamie LeBlanc Hitendra Kumar Hongguang Zhang Weijun Yang Xiao He Qingye Lu Jeffrey Van Humbeck Keekyoung Kim Jinguang Hu | 2023 | Journal of Bioresources and Bioproducts2023,8,2: | 0 |
| 15 | 浓H3PO4联合H2O2预处理能源植物地肤的性能研究显示文摘采用H3PO4联合H2O2(简称PHP)预处理地肤,基于木质素、半纤维素去除率、纤维素回收率、酶水解率等,研究温度、时间、H3PO4与H2O2浓度配比对预处理效果的影响。结果表明:提升预处理温度、时间和H3PO4浓度配比对半纤维素和木质素去除率有明显的促进作用,半纤维素和木质素去除率最大可达100.0%和90.7%,但也会加剧纤维素的损失。过高的H3PO4浓度配比(≥70%)不利于半纤维素和木质素去除。除10℃外,其他条件下,酶水解率差异不显著(>90%),但过高强度会导致一定程度的水解速率下降。 | 郑循雯 彭天娇 邱婧雯 沈飞 Jinguang Hu | 2020 | 太阳能学报2020,41,7: | 0 |
| 16 | Will biomass be used for bioenergy or transportation biofuels? What drivers will influence biomass allocation显示文摘Potential competition for biomass for current and future bioenergy/biofuel uses in Brazil, Denmark,Sweden and the USA were compared. In each of these countries, bioenergy and biofuels are already important in their energy mix. However, there is limited competition for biomass between bioenergy(heat/power/residential/industrial) and transportation biofuel applications. This situation is likely to continue until advanced biofuel technology becomes much more commercially established. In each of these countries, biomass is predominantly used to produce bioenergy, even in those regions where biofuels are significant component of their transportation sector(Brazil,Sweden and USA). The vast majority of biofuel production continues to be based on sugar, starch and oil rich feedstocks, while bioenergyis produced almost exclusively from forest biomass with agricultural biomass having a small, but increasing, secondary role. Current and proposed commercial scale biomass-to-ethanol facilities almost exclusively use agriculture derived residues(corn stover/wheat straw/sugarcane bagasse). Competition for biomass feedstocks for bioenergy/biofuel applications, is most likely to occur for agricultural biomass with coproduct lignin and other residues used to concomitantly produce heat and electricity on site at biofuel production facilities. | Jinguang HU William James CADHAM Susan van DYK Jack N.SADDLER | 2017 | Frontiers of Agricultural Science and Engineering2017,4,4: | 0 |
