In this study, a novel deposition technique that utilizes diethylzinc (C₄H₁₀ZnO) with H₂O to form a ZnO adhesion layer was proposed. This technique was followed by the deposition of vaporized nickel(II) 1-dimethylamino-2-methyl-2-butoxide (Ni(dmamb)₂) and H₂ gas to facilitate the deposit of uniform layers of nickel on the ZnO adhesion layer using atomic layer deposition. Deposition temperatures ranged from 220 to 300 °C. Thickness, composition, and crystallographic structure results were analyzed using spectroscopic ellipsometry, scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD), respectively. An average growth rate of approximately 0.0105 angstroms per cycle at 260 °C was observed via ellipsometry. Uniform deposition of ZnO with less than 1% of Ni was displayed by utilizing the elemental analysis function via SEM, thereby providing high-quality images. XPS revealed ionizations consistent with nickel and ZnO through the kinetic and binding energies of each detected electron. XRD provided supplemental information regarding the validity of ZnO by exhibiting crystalline attributes, revealing the presence of its hexagonal wurtzite structure.

本研究提出了一种利用二乙基锌（C4H10ZnO）与 H2O 形成氧化锌附着层的新型沉积技术。随后，利用原子层沉积技术将气化的镍(II) 1-二甲氨基-2-甲基-2-丁醇（Ni(dmamb)2）和 H2 气体沉积在氧化锌附着层上，以促进镍层的均匀沉积。沉积温度为 220 至 300 °C。使用光谱椭偏仪、扫描电子显微镜（SEM）、X 射线光电子能谱（XPS）和 X 射线衍射（XRD）分别分析了厚度、成分和晶体结构结果。通过椭偏仪观察到，在 260 °C 温度下，平均生长速率约为每周期 0.0105 埃。通过扫描电子显微镜的元素分析功能，显示出氧化锌的均匀沉积，镍含量低于 1%，从而提供了高质量的图像。XPS 通过每个检测到的电子的动能和结合能显示出与镍和氧化锌一致的电离。XRD 提供了有关氧化锌有效性的补充信息，显示了其结晶属性，揭示了其六方菱形结构的存在。

Investigating the behavior of cardiomyocytes is an important part of drug development. We present a structure and a related nanoimprint-based fabrication method, where the cardiomyocytes form isolated fibers, which is beneficial for drug testing, more closely representing the structure of the cardiomyocytes in vivo. We found that channel structures with walls with a rough top surface stimulate cardiomyocytes to form such fibers, as desired. Nanoimprint lithography is used as a fast and cost-efficient method to fabricate our hierarchically structured cell growth substrates.

This article reports on polymer (PLLA, poly(L-lactic acid)) nanosheets incorporated with Fe-ion nanoparticles, aiming at using the latter nanoparticles as a source to release Fe ions. Such Fe ions should facilitate burn wound healing when such nanosheets are applied as a biomedical tissue on skin. Laser ablation in liquid phase was used to produce Fe-containing nanoparticles that, after incorporation into PLLA nanosheets, would release Fe ions upon immersion in water. Unlike most iron-oxide nanostructures, which are poorly soluble, such nanoparticles prepared in chloroform were found to have water solubility, as they were shown by XPS to be based on iron chloride and oxide phases. After incorporation into PLLA nanosheets, the ion-release test demonstrated that Fe ions could be released successfully into water at pH 7.4. Incorporation with two different metal ions (Fe and Zn) was also found to be efficient, as both types of ions were demonstrated to be released simultaneously and with comparable release rates. The results imply that such polymer nanosheets show promise for biomedical applications as potential patches for healing of burns.

本文报道了掺入铁离子纳米粒子的聚合物(PLLA，聚l -乳酸)纳米片，旨在利用后者作为释放铁离子的源。当这种纳米片作为生物医学组织应用于皮肤时，这些铁离子应该促进烧伤伤口愈合。采用液相激光烧蚀法制备含铁纳米颗粒，将其掺入PLLA纳米片后，浸入水中释放铁离子。与大多数难溶的氧化铁纳米结构不同，在氯仿中制备的这种纳米颗粒具有水溶性，因为XPS显示它们是基于氯化铁和氧化物相。将铁离子掺入PLLA纳米片后，离子释放测试表明，铁离子可以成功释放到pH为7.4的水中。与两种不同的金属离子(铁和锌)结合也被发现是有效的，因为两种类型的离子被证明是同时释放的，并且释放速率相当。结果表明，这种聚合物纳米片作为烧伤愈合的潜在贴片在生物医学上有很大的应用前景。

Chitin (usually derived from aq. arthropods like shrimp Pandalus borealis) acts as a potent metal sorbent in both environmental monitoring and retention applications such as wastewater purification or nuclear fuel reprocessing. Given this established (starting in the 1970s) use of chitin and the fact that adsorption of metal ions/complexes to chitin does increase the currents observed in metal-centered redox couples by a factor of about 10, it is straightforward to conceive self-organized (by adsorption modified by adding certain ligands bridging M and chitin) surface films which exert electrical information processing by means of inner-sphere redox processes. Preliminary work is shown concerning the influence of ligands—including some possibly acting as inner-sphere-transfer agents, like caffeic acid—on metal ion retention by chitin. Another ligand is reported to enhance current flow into electrodes (i.e., electron injection from some reducing cation). These inner-sphere redox processes, in turn, can be controlled by creating or removing a chain of conjugated double bonds, e.g., by Diels–Alder reactions. Devices admitting corresponding reagents in a controlled manner and appropriate array then act as NAND gates, thus being components capable of performing each kind of classical computation. Applications in environmental analysis and “green” computing for simple purposes like electronic keys are suggested. The empirical basis for these conclusions includes studies on the influences of ligand additions on M adsorption (Mn, Ni, several REEs…) on chitin; some of these bridging ligands, like caffeinate and ferulate, can reversibly react with appropriate dienes. At the employed concentrations, distances among adsorbed metal ions are 1–3 nm, meaning that the charge-flow control takes spacer ligands like carotenoids. Practical setups are pointed to, using evidence from ligand-augmented metal ion–chitin interactions, which might combine oxidizing (Ce) and optically address reducing (Eu) metal ions into a framework for coligand-controlled charge flow.

几丁质(通常来自北方熊猫虾等节肢动物)在环境监测和废水净化或核燃料后处理等保留应用中都是一种有效的金属吸附剂。考虑到这种已建立的(从20世纪70年代开始)甲壳素的使用，以及金属离子/配合物对甲壳素的吸附确实使金属中心氧化还原偶中观察到的电流增加了约10倍的事实，我们可以直接设想自组织(通过添加连接M和甲壳素的某些配体修饰的吸附)表面膜通过球内氧化还原过程施加电信息处理。初步研究表明配体(包括一些可能作为球内转移剂的配体，如咖啡酸)对几丁质保留金属离子的影响。据报道，另一种配体可以增强电流流入电极(即来自某些还原阳离子的电子注入)。这些内球氧化还原过程，反过来，可以通过创建或去除一条共轭双键链来控制，例如，通过Diels-Alder反应。以可控的方式接纳相应试剂的器件和适当的阵列充当NAND门，从而成为能够执行各种经典计算的元件。建议应用于环境分析和简单用途的“绿色”计算，如电子钥匙。这些结论的经验基础包括:研究配体添加对M (Mn、Ni、几种稀土等)在甲壳素上吸附的影响;其中一些桥接配体，如咖啡酸盐和阿魏酸盐，可以与适当的二烯发生可逆反应。在所使用的浓度下，吸附金属离子之间的距离为1-3纳米，这意味着电荷流控制需要像类胡萝卜素这样的间隔配体。利用配体增强金属离子-几丁质相互作用的证据，指出了实际的设置，这可能将氧化(Ce)和光学寻址还原(Eu)金属离子结合到一个配体控制电荷流的框架中。
