纳米medicine: From increasing tissue growth to toxicity concerns

东北大学化学工程系Thomas J. Webster

Inspired from biological systems, nanotechnology is beginning to revolutionize medicine including improved prevention, diagnosis, and treatment of numerous diseases. This talk will summarize efforts over the past decade that have synthesized novel nanoparticles, nanotubes, and other nanomaterials to improve medicine. Efforts focused on the use of nanomaterials to minimize immune cell interactions, inhibit infection, and increase tissue growth will be especially emphasized.

最近涉及纳米粒子毒性的担忧也将被涵盖以及使纳米颗粒的策略减轻毒性。总之,这次谈判将提供有关再生医学中无数纳米材料的设计和使用的最新信息,同时突出了该领域继续增长所需的内容。


石墨烯中的热量和噪音:独特的性能和实用应用

Alexander A. Balandin, Department of Electrical Engineering and Materials Science and Engineering Program, University of California – Riverside

Unique electronic properties of two-dimensional (2D) graphene originate from its unusual linear Dirac-cone dispersion. Phonons – quanta of lattice vibrations – in 2D crystals also reveal features different from those in bulk materials. In 2008, we discovered that the phonon thermal conductivity of suspended graphene can be exceptionally high – exceeding that of the basal graphite planes.

This presentation will review the results of optothermal Raman measurements, and describe practical applications of graphene in the thermal management of electronics. We will also discuss graphene electronic applications that do not require an energy band-gap including graphene-on-diamond interconnects with exceptional current-carrying capacity, low-noise graphene transistors for analog electronics and communications, phase detectors and selective gas sensors implemented with pristine graphene.


胶体纳米颗粒的可控合成:How high quality can benefit new discoveries

Yugang Sun,纳隆纳国家实验室纳米级材料中心

胶体纳米粒子的合成具有量身定制的属性为探索其在许多有前途的地区的应用程序提供了基础,例如能量收集/转换/储存,催化,电子产品等。在本演示文稿中,我将突出一些允许我们工程师的指导方针通过以控制尺寸和形态学合成银纳米颗粒作为实例,通过将银纳米颗粒合成而参与胶体纳米颗粒生长的临界成核步骤。

In the second part of the presentation, reversing size-dependence of optical properties of the synthesized silver nanoparticles and exceptional tetragonal crystalline symmetry of the silver nanowires will be highlighted to shed a light on how to use the well-synthesized nanoparticles as a platform to discover the unique properties associated with nanometer dimensions.

纳米-boron-nitrides

Dmitri Golberg, World Premier International (WPI), Center for Materials Nanoarchitectonics (MANA), National Institute for Materials Science (NIMS), Tsukuba, Japan

Boron nitride (BN) nanomaterials, i.e. nanotubes and nanosheets, have long been in a shadow of their popular carbon (C) cousins. However, recently, these exciting nanostructures have started to attract the full attention of materials scientists and engineers. NanoBNs are much more thermally and chemically stable compared to their C counterparts, while possessing approximately the same values of mechanical strength and thermal conductivity. Specific features of these nanomaterials include stable electrical insulation and radiation protecting properties. Therefore, nanoBNs are rich in exciting structural and functional application potentials.

多年来,我们在日本筑波筑坝的小组群体一直在研究和利用各种领域的BN纳米管和纳米片,从聚合物,陶瓷和金属中的增强剂,到现场发射和激光应用。在这次谈话中,我将审查丰富的BN纳米材料领域,特别突出了“白色”BN石墨烯的新和蓬勃发展的领域。

作者感谢许多过去,并在尼姆斯的同事上为他们对这次谈话主题的巨大贡献。


二肽水凝胶

Dave J. Adams, Department of Chemistry, University of Liverpool

Low molecular weight gelators (LMWG) form gels by the self-assembly of the LMWG into long fibres. These fibres entangle and, at a suitable concentration, lead to the network that gives rise to the solid-like properties of the gels. Many LMWG exist, with very different molecular structures. Paradoxically, it is also clear that slight changes in molecular structure can result in a LMWG becoming a non-gelator. Linking the molecular structure to the mechanical properties of the gels is difficult. One reason for this is that it is becoming increasingly clear that the method of assembly is a critical parameter in determining the properties of the gel. The self-assembly for LMWG can be induced by a variety of stimuli including pH, temperature and solvent polarity. Each of these methods can lead to a different self-assembly pathway. Here, we describe the formation of hydrogels from dipeptide-based LMWG. Depending on the assembly process, gels can be prepared which have widely differing properties. We will show how the properties of the gels can be controlled.
