纳米尺度的生物铁氧化物/氢氧化物是microetoelectronics有前途的选择。他们一直在使用“体内”核磁共振实验,为更好的对比。最近开发的生物技术是专注于获取新的物理数据的应用在电子和医学生物材料由于新陈代谢在实验室条件下获得iron-oxidizing属纤毛菌属的细菌。粉末和涂层玻璃样本进行调查。分析收集的数据表明,不同价从媒体的增长有可能变成Fe3 +的形式或Fe2.5 +两种类型的氧化物/氢氧化物(氧)如纤铁矿(ɣ-FeOOH)和磁铁矿(Fe3O4),与纳米形态。粒子的大小(低于30海里)和晶体结构的bioproducts进行了XRD、SEM、TEM、穆斯鲍尔和拉曼光谱。结构偏差是观察到生物铁氧化物/氢氧化物相比与传统材料。结果进一步证明纤铁矿的主要产品是细菌的新陈代谢,在电影和沉积物的粉末。Fe3O4经过中间相的形成——“绿锈”反应和数量控制在准备。工作报告的结果是基于鱿鱼在磁性测量生物ferroxides - M (T)。 Monodomain particles which are antiferromagnetic - ɣ-FeOOH and ferrimagnetic - Fe3O4 were received. For the needle like crystals of lepidocrocite the outer casing deviations were observed which modified the magnetic properties about 50 K. The new biogenic materials showed superparamagnetic behavior and high sensitivity to electromagnetic radiation. The biogenic tubular formation with a single-phase iron oxides/hydroxides inclusions in biogenic matrix was also investigated. Contributions for understanding the structural, magnetic and optical properties are important for fundamental research, but also some suggestions for potential applications in electronics and information technologies are proposed.
