有害细菌黏附在各种材料表面会时刻危害着人类生命健康,每年为应对有害细菌黏附所付出的经济成本数以亿计。黏附在材料表面的细菌最终将形成难以清除的生物膜,预防细菌在初始阶段的黏附可以显著减少生物膜的形成,这是应对细菌黏附的有效途径。迄今为止,预防细菌的初始黏附所采用的手段包括超疏水表面、超亲水表面、润滑表面和智能响应型防黏附表面等。但上述提到的绝大多数抗细菌黏附手段属于静态的被动式抗细菌黏附策略,本研究提出了一种基于重力驱动实现液滴定向运输的主动式抗细菌黏附策略,并且结合银纳米粒子负载的杀菌区构建了一种新型主动式抗细菌黏附系统。通过实验探究了微坡高度、倾角与液滴运动的关系,并得到了最优条件。动态抗细菌黏附测试发现对大肠杆菌和金黄色葡萄球菌的抗黏附率高达99.71%和98.79%,具有良好的主动抗细菌黏附效果,验证了重力驱动细菌液滴定向运输主动式抗细菌黏附策略的有效性。末端杀菌区不但具有良好的被动抗黏附效果,并且可以有效地杀死运动至杀菌区的细菌液滴,对大肠杆菌和金黄色葡萄球菌的抗菌率高达100%和100%。本研究提出的基于重力驱动实现液滴定向运输的主动式抗细菌黏附策略的抗黏附效果显著,构建的整个新型主动式抗细菌黏附系统具有良好的抗细菌黏附和杀菌能力,为应对细菌黏附提供了一种全新的策略,在生物医学、微流控技术和工业生产等领域具有重要的应用前景。

Although many material designs or strategic methods have been proposed for treating oil spills and oily wastewater,the complex oily state,dealing with the harsh operating conditions of oil–water separation(such as the recovery of viscous spilled crude oil,bacteria-containing oily wastewater,and removal of spilled oil under fire),and the autorecycling of oil and absorption materials remain a great *** work proposed an ingenious design strategy of“several birds with one stone”to prepare p H/thermoresponsive flame-retardant/photothermal bactericidal P-Fe_(3)O_(4)-polydopamine(PDA)@melamine–formaldehyde(MF)*** design makes the foams remarkably effective in the recovery of spilled viscous crude oil as well as in the separation of bacteria-containing oily emulsions,particularly for instant fire extinguishing by magnetically controlled oil absorption as well as for fire *** photothermal effect and p H response induce a change in the surface wettability of the foams,facilitating excellent autoadsorption/desorption of the spilled *** photothermal bactericidal activity and fouling resistance of the foam are beneficial to the separation of bacteria-containing oily *** flame-retardant properties and maneuverable magnetic control enable the foam to rapidly recover the spilled oil in a large range of fires,extinguish fires instantly,and facilitate early fire *** proposed strategy is expected to inspire further research on treating oil spills under complex conditions.

Amorphous Ni-Ru-B/ZrO2 catalysts were prepared by chemical reduction method. The effects of Ni-Ru-B loading and Ru/Ni mole ratio on the catalytic performance for selective CO methanation from reformed fuel were studied, and the catalysts were characterized by BET, ICP, XRD and TPD. The results showed that Ru strongly affected the catalytic activity and selectivity by increasing the thermal stability of amorphous structure, promoting the dispersion of the catalyst particle, and intensifying the CO adsorption. For the catalysts with Ru/Ni mole ratio under 0.15, the CO methanation conversion and selectivity increased significantly with the increasing Ru/Ni mole ratio. Among all the catalysts investigated, the 30 wt% Ni-Ru-B loading amorphous Ni61Ru9B30/ZrO2 catalyst with 0.15 Ru/Ni mole ratio presented the best catalytic performance, over which higher than 99.9% of CO conversion was obtained in the temperature range of 230℃-250℃, and the CO2 conversion was kept under the level of 0.9%.

Nano ZrO2 and MgO-ZrO2 were prepared by a self-assembly route and were employed as the support for Ni catalysts used in hydrogen production from glycerol reforming in supercritical water （SCW）. The reforming experiments were conducted in a tubular fixed-bed flow reactor over a temperature range of 600-800 ℃. The influences of process variables such as temperature, contact time, and water to glycerol ratio on hydrogen yield were investigated and the catalysts were charactered by ICP, BET, XRD and SEM. The results showed that high hydrogen yield was obtained from glycerol by reforming in supercritical water over the Ni/MgO-ZrO2 catalysts in a short contact time. The MgO in the catalyst showed significant promotion effect for hydrogen production likely due to the formation of the alkaline active site. Even when the glycerol feed concentration was up to 45 wt%, glycerol was completely gasified and transfered to the gas products containing hydrogen, carbon dioxide, and methane along with small amounts of carbon monoxide. At a diluted feed concentration of 5 wt%, near theoretical yield of 7 mole of H2/mol of glycerol could be obtained.
