Nano-structure formation and function control of colloidal materials due to strong magnetic fields

由弱磁系统组成的胶体尺寸组合，如水凝胶、脂质囊泡、凝聚体、三嵌段聚合物/硅酸盐杂化物、介孔二氧化硅和有机金属配合物，在磁场作用下被组织和功能化。从多孔固体和生物材料的磁响应结构的角度研究了磁场的势能。研究了各种结构在磁场作用下的自组织和各向异性添加剂对功能的磁场敏化作用。这一初步成功为基于磁性控制各向异性非纹理和纳米结构提供了一种新的、简单的方法。例如，在相同的反应物、溶液和条件下，利用磁场制备了两种新型铜吡嗪配合物。这导致磁性各向异性源于晶体结构。此外，液液混合物中的浓度波动在磁场梯度产生的磁场下得到控制，并通过动态和静态光散射检测。研究了磁场作用下非线性化学反应中金属结构的形成。体积相变凝胶和囊泡在外加磁场作用下发生变形，磁性各向异性分子的加入增强了这种磁变形。H_2在不同碳（包括单壁碳纳米管）上的磁吸附率与温度有显著的关系。磁场对H_2蒸气的吸附量远大于超临界气体。在蒸气区，压力变化Ap依赖于T^<-1.4>。另一方面，在超临界区，Δp在40K以下依赖于（T-Tc）^< -0.09>，在40-303K范围内依赖于（T-Tc）^<-0.34>，表明微孔中存在超临界态的两种磁性状态。在此基础上，利用氢碳吸附体系构建了新的隧道反应体系，隧道反应由磁场控制。是否有所谓的磁化水被检查。经过周密的研究表明，纯水并没有被“磁化”，而是暴露在氧气中的水通过磁处理被“磁化”了。水的“磁化”程度可以用接触角来定量地、容易地评价。少

Colloid-dimensional assemblies comprising weak magnetic systems, such as hydrogels, lipid vesicles, coacervates, triblockpolymer/silicate hybrids, mesoporous silicas, and organometal complex, were organized and functionalized by magnetic fields. Potential ability of magnetic fields were investigated from the viewpoint of magnetically responsive structures in porous solids and biological materials.Self-organization of various structures due to magnetic fields and magnetic-field sensitization of functions due to additives with magnetic anisotropy were examined. This preliminary success led to a new, simple method to control anisotropic nono-textures and nano-structures based on their magnetism. For examples, two kinds of new cupper-pyrazine complexes were prepared from the same reactants solution and conditions, besides using magnetic fields. This results in magnetic anisotropy originated from crystal structure. Moreover, concentration fluctuation in liquid-liquid mixtures was controlled … More under magnetic force fields produced by magnetic field gradient, and detected by dynamic and static light scattering. Metal structure formation associated with non-linear chemical reaction was examined under magnetic fields. Volume phase transition gels and vesicles were deformed by external magnetic fields and the magnetic deformation was enhanced by the addition of magneitically anisotropic molecules.The magnetoadsorptivity of H_2 onto various carbons including a single wall carbon nanotube depended markedly on temperature. H_2 vapor was adsorbed much larger than the supercritical gas by magnetic field. In the vapor region, the pressure change Ap depends on T^<-1.4>. On the other hands, in the supercritical region, Δp depends on ( T-Tc)^<-0.09> below 40K and (T-Tc)^<-0.34> in the range 40-303K, suggesting two magnetic states of supercritical states in the micropores. Based on the results, new tunneling reaction systems were constructed using adsorption systems comprising hydrogen and carbons, and the tunneling reactions were controlled by magnetic fields.Whether or not there is so-called magnetized water was examind. Very elaborate investigation showed that pure water was not "magnetized", but the water exposed to oxygen was "magnetized" by magnetic treatment. The degree of "magnetization" of water can be quantitatively and easily evaluated by the contact angle. Less
