direct air capture(dAC)of CO_(2)plays an indispensable role in achieving carbon-neutral goals as one of the key negative emission *** large air flows are required to capture the ultradilute CO_(2)from the air,lab-synthesized adsorbents in powder form may cause unacceptable gas pressure drops and poor heat and mass transfer efficiencies.A structured adsorbent is essential for the implementation of gas-solid contactors for cost-and energy-efficient dAC *** this study,efficient adsorbent poly(ethyleneimine)(PEI)-functionalized Mg-Al-CO_(3)layered double hydroxide(LdH)-derived mixed metal oxides(MMOs)are three-dimensional(3d)printed into monoliths for the first time with more than 90%adsorbent *** printing process has been optimized by initially printing the LdH powder into monoliths followed by calcination into MMO *** structure exhibits a 32.7%higher specific surface area and a 46.1%higher pore volume,as compared to the direct printing of the MMO powder into a *** impregnation of PEI,the monolith demonstrates a large adsorption capacity(1.82 mmol/g)and fast kinetics(0.7 mmol/g/h)using a CO_(2)feed gas at 400 ppm at 25℃,one of the highest values among the shaped dAC *** of the amino-polymers during the post-printing process affects the diffusion of CO_(2),resulting in slower adsorption kinetics of pre-impregnation monoliths compared to post-impregnation *** optimal PEI/MeOH ratio for the post-impregnation solution prevents pores clogging that would affect both adsorption capacity and kinetics.

At present,there is a shortage of experimental and simulation studies on fire spread in medium-and large-scale compartments while the existing models of the fire spread are limited for typical engineering *** paper proposes a new model for large-scale fire spread on medium density fibreboard(MdF)*** the model with single burning item(SBI)experiments,it is found that the numerical simulation closely predicts the experimental heat release rate(HRR)with some error near the *** predicted heat flux and distance of lateral flame spread are consistent with the experiments and an existing *** effects of kinetic properties and heat of combustion are identified through a sensitivity *** decrease of activation energy and increase of pre-exponential factor make the MdF easier to pyrolyze and the increase of heat of combustion enhances the flame temperature and thus provide more heat feedback to the sample *** low activation energy(71.9 kJ/mol)and high heat of combustion(46.5 MJ/kg)of the model ensure the occurrence of flame ***,the model was validated using medium-scale compartment fire experiments and the results showed that the model can accurately predict the HRR after flashover(the error is within 7%).While the burner is ignited,the predictions of in-compartment gas temperature and heat flux are more ***,when the burner is extinguished,the modelled in-compartment gas temperature is lower than the experimental values,resulting in a lower heat flux *** model leads to easier flame spread;therefore,the modelled flame spreads faster in the compartment compared to the experiment,and thus the HRR increases more rapidly.

The Natural Killer Cell (NKC) is the cell-mediated cornerstone of innate immunity. The purpose of this reviewis to give a historical perspective of the discovery of the Natural Killer Cell (NKC)and to apply the use of supplements in the enhancement of NKC in human cancers for the developmentof human health and *** the discovery of the NKC, as observed by Nomarski optics, scanning (SEM)/transmission electron microscopy (TEM) with cellular numeration and enrichment using bovine serum albumin (BSA) continuous gradients, there have been significant research and clinical studies to increase the effectiveness of NKC in the destruction of cancer cells. Based on significant research and clinical studies, at least 16 components have been identified that enhance or may enhance, based on their immune modulator activity, the NKC. These supplements include Alpha LipoicAcid, Arabinoxylin, Curcumin, Garlic, Genistein, Ginseng, Lentinan, Mistletoe, N-Acetylcysteine, Resveratrol, Selenium, Vitamin B, Vitamin C, Vitamin d3, Vitamin E and zinc.

在阿拉斯加Prudhoe Bay油藏的一组建议注水的模拟中进行了重力正演、反演模拟。一种通过地面重力观测未监测8200ft(2500m)深处储层中气顶注水进程的新监测技术已开发出来。这种经济有效的方法要求在数年内重复进行高精度的重力勘探。重力场随时间的变化反映出储层内流体密度的变化。在Prudhoe Bay油田进行的初次现场试验表明:把改进的Lacoste&Romberg"G"型重力仪或Scintrex CG-3M型重力仪和NAVSTAR全球定位系统(GPS)联合使用,勘探精度可达5μGal～10μGal正演重力模拟预测注水5年后地表测量的变化量为100μGal,15年后为180μGal～250μGal。我们采用约束最小二乘法对合成重力数据进行反演,以得到地下密度分布。模拟步骤已写成公式并已编成程序以便于测试模型对重力采样模式、噪声类型以及对各种模型参数(如密度、总质量和惯性矩)的约束的灵敏度。对于具有5μGal标准偏差(Sd)噪声的合成重力数据的约束反演模型,其注水的水平特征分辨率大约为5000ft(1520m)。反演方法可以计算注入的总水量,误差在几个百分点之内受高级别的空间相关噪声(大于10μ～15μGal Sd)干扰的重力数据的反演可导致最糟糕的结果在这种情况下根据反演模型估算的总质量可能会将质量高估或低估10%～20%。模拟结果表明时间推移重力数据的反演对于监测储层气顶注水是一项可行的技术。

由于羟基磷灰石陶瓷与骨无机质的化学成份相似,所以10年来研究者对羟基磷灰石陶瓷在骨修复替换中的应用进行了深入的研究。羟基磷灰石因其高生物相容性和骨传导性已被广泛的应用,但羟基磷灰石的再吸收能力差。文章对由硅酸钙、β-磷酸三钙和羟基磷灰石组成的三相陶瓷复合物进行了研究。在三相陶瓷复合物环境下,采用不同比率硅酸钙、β-磷酸三钙和羟基磷灰石对骨髓夹源间充质干细胞进行体外研究。细胞在加入和没有加入成骨细胞的情况下培养28d。采用碱性磷酸酶活性、碱性磷酸酶基因码转录和骨唾液蛋白Ⅱ表达评估成骨分化水平。成骨细胞和破骨细胞在陶瓷复合80%羟基磷灰石材料上完成预实验。将鼠颅盖骨成骨细胞与人单核细胞共同培养以分析其向破骨细胞分化的可能性。结果显示人骨髓间充质干细胞在陶瓷复合物材料上表现出快速黏附和高度增殖率,在所有实验材料上,成骨诱导的骨髓间充质干细胞碱性磷酸酶活性增加,碱性磷酸酶基因码转录和骨唾液酸蛋白Ⅱ的表达在3种材料上同样增加。扫描电镜和聚焦激光扫描显微镜结果证明在陶瓷复合80%羟基磷灰石材料上的人单核细胞向破骨样细胞分化。结果提示制备的三相陶瓷复合材料支持人骨髓间充质干细胞的黏附、增殖和成骨分化,以及人单核细胞与成骨细胞联合培养条件下破骨细胞形成。
