| 1 | Tuning Superhydrophobic Materials with Negative Surface Energy Domains显示文摘Hydrophobic/superhydrophobic materials with intrinsic water repellence are highly desirable in engineering fields including antiicing in aerocrafts,antidrag and anticorrosion in ships,and antifog and self-cleaning in optical lenses,screen,mirrors,and windows.However,superhydrophobic material should have small surface energy(SE)and a micro/nanosurface structure which can reduce solid-liquid contact significantly.The low SE is generally found in organic materials with inferior mechanical properties that is undesirable in engineering.Intriguingly,previous theoretical calculations have predicted a negative SE forθ-alumina(θ-Al_(2)O_(3)),which inspires us to use it as a superhydrophobic material.Here,we report the experimental evidence of the small/negative SE ofθ-Al_(2)O_(3) and aθ-Al_(2)O_(3)-based superhydrophobic coating prepared by one-step scalable plasma arcing oxidation.The superhydrophobic coating has complete ceramic and desired micro/nanostructure and therefore exhibits excellent aging resistance,wear resistance,corrosion resistance,high-temperature tolerance,and burning resistance.Owing to the rarity of the small/negative SE in inorganic materials,the concept to reduce SE byθ-Al_(2)O_(3) may foster a blowout to develop robust superhydrophobicity by complete inorganic materials. | Zhongzhen Wu Liangliang Liu Shunning Li Shunping Ji Pinghu Chen Suihan Cui Zhengyong Ma Yuchang Weng Qian Huang Zhongcan Wu Hao Wu Yuan Lin Ricky KYFu Hai Lin Xiubo Tian Paul KChu Feng Pan | 2019 | Research2019，，1： | 6 |
| 2 | Synergic catalytic effect of Ti hydride and Nb nanoparticles for improving hydrogenation and dehydrogenation kinetics of Mg-based nanocomposite显示文摘The Mg-9.3 wt%(TiH_(1.971)-TiH)-0.7 wt% Nb nanocomposite has been synthesized by hydrogen plasma-metal reaction(HPMR) approach to enhance the hydrogen sorption kinetics of Mg at moderate temperatures by providing nanosizing effect of increasing H 'diffusion channels' and adding transition metallic catalysts. The Mg nanoparticles(NPs) were in hexagonal shape range from 50 to 350 nm and the average size of the NPs was 177 nm. The small spherical TiH_(1.971), TiH and Nb NPs of about 25 nm uniformly decorated on the surface of the big Mg NPs. The Mg-TiH_(1.971)-TiH-Nb nanocomposite could quickly absorb 5.6 wt% H_2 within 5 min at 573 K and 4.5 wt% H_2 within 5 min at 523 K, whereas the pure Mg prepared by HPMR could only absorb 4 and 1.5 wt% H_2 at the same temperatures. TiH_(1.971), TiH and Nb NPs transformed into TiH_2 and Nb H during hydrogenation and recovered after dehydrogenation process. The apparent activation energies of the nanocomposite for hydrogenation and dehydrogenation were 45.0 and 50.7 kJ mol^(-1), which are much smaller than those of pure Mg NPs, 123.8 and 127.7 kJ mol^(-1). The improved sorption kinetics of the Mg-based nanocomposite at moderate temperatures and the small activation energy can be interpreted by the nanostructure of Mg and the synergic catalytic effects of Ti hydrides and Nb NPs. | Xiujuan Ma Xiubo Xie Peng Liu Li Xu Tong Liu | 2017 | Progress in Natural Science:Materials International2017，27，1： | 2 |

| 5 | Purification of four strains of endophytic fungi from Astragalus and their optimized liquid fermentations显示文摘This study was designed to isolate endophytic fungi from A. mongholicus(growing in northeast China) to determine whether they can produce bioactive metabolites. Four strains of endophytic fungi(strains 16, 17, 23 and 75) were successfully isolated from A. mongholicus using the surface disinfection method. According to ITS-rDNA sequences analysis, strains 16 and 75 were identified as Fusarium oxysporum, and strains 17 and 23 were identified as Bionectria ochroleuca. We applied the Box-Behnken design(BBD) to optimize the liquid fermentation conditions and obtain the maximum cell dry weight(CDW) yield. Optimal parameters were obtained under the following experimental conditions: temperature of 28°C, potato dextrose agar(PDA) liquid medium of 80 mL and rotation speed of 150 rpm. The four isolated endophytic fungi did not produce astragalosides I–IV, flavonoids or polysaccharides. Isolation of additional species of endophytic fungi from A. mongholicus and determination of their capacity to produce biologically active substances are subjects in need of further research. | Wei Ma Xiubo Liu Jiao Jiao Leiming Zhang Weichao Ren Ling Ma Xiangjun Kong Ning Zhang Xiwu Zhang | 2014 | Journal of Forestry Research2014，25，3： | 1 |
