查询词典 membranes

The experiments show that TiO〓 nanowire arrays have higher photodecomposition efficiency than TiO〓 film. It is due to not only their higher surface area, but also their wider energy gap. 6. Ordered NiO nanowire arrays embedded in anodic alumina membranes have been prepared by using an electrochemical deposition method. Thermogravimetry curve shows that NiOH embedded in AAO decomposed slowly compared to thin film.

可能存在两个原因：氧化钛纳米丝具有比氧化钛纳米膜更大的比表面积；氧化钛纳米丝的光学带隙大于氧化钛纳米膜的，带宽的增加，使得价带电子电位变得更正，导带电位变得更负，这实际上增加了光生电子和空穴的氧化还原能力，提高了半导体光催化氧化有机物的活性。

The structure and properties of plasticized membranes were studied in the condition of different plasticization by mechanical property measurement,surface observation,and FT-IR analysis.

纤维素是自然界广泛存在的可再生的天然资源，据专家统计，全球每年利用植物合成可生产数干亿吨的纤维素，这是石油无法与其相比的[1]。

In the current study, a series of cationic α-helical peptides of 20 a.a. were designed and synthesized based on four structural parameters, including charge, polar angle, hydrophobicity, and hydrophobic moment. Several methods were performed to describe the influence of these parameters on the antimicrobial and hemolytic activity, and on the permeabilizing effect on model membranes. The potential of these parameters to increase the antibacterial activity and to improve the prokaryotic selectivity is assessed.

本实验利用自行设计合成的人工抗菌胜肽当模型，固定长度为 20 个胺基酸，改变其电荷、极性角度、疏水性及疏水性矩等四种结构特性，并利用其对各种不同病原菌之抗菌活性及对兔子红血球细胞的溶血活性来研究其结构特性的改变对其抗菌活性、选择性及微脂体膜的渗透性之影响，以期望改变结构参数能增加抗菌活性及对原核的选择性。

The experimental results showed the air and water vapor permeability of polyurethane membranes are improved.

结果表明，白木粉的加入能改善聚氨酯膜的透气和透汽性能。

This investigation describes the one step preparation of potassium carbonate by electrolysis of potassium chloride solution in the electrolyzers with various kinds of Nafion membranes.

采用添加KHCO_3的阴极液循环法，由KCl水溶液的离子膜电解，一次得到K_2CO_3。试验中对Nafion膜的导电度进行了测定，探讨了碱金属阳离子在离子膜中的行为。

Membrane affinity quantified by IAM and liposome/buffer systems was a more efficient predicator of α values than hydrophobicity from n-octanol/buffer system. Consequently, not only hydrophobic force but also attractive polar extra-interactions involved in the binding to IAM and liposomal membranes but not in an n-octanol phase, ascribed to the binding process within AM. The binding to ordered lipid membrane in the larger part determined drugs'binding to AM intracellular compositions, and the ordered phospholipid plasma membrane was a potential site for drugs'binding in AM.

脂质体／水系统和磷脂膜色谱所测定的膜亲和性比正辛醇／水系统的疏水性更好的预测巨噬细胞内药物的α值，因此包含在磷脂膜色谱中但并不体现在正辛醇／水系统中药物与磷脂膜之间的额外吸引性极性作用力对药物在细胞内结合有着重要贡献；药物与有序磷脂膜的结合在很大程度上决定着药物与巨噬细胞内成分的结合，有序磷脂分子膜可能是巨噬细胞内部潜在的结合部位。
