Mimicking the nanostructure of bone matrix to regenerate bone 模拟骨基质的纳米结构到可再生骨
Robert Kane, Peter X. Ma
Key features of bone tissue structure and composition are capable of directing cellular behavior toward the generation of new bone tissue. Bone tissue, as well as materials derived from bone, have a long and successful history of use as bone grafting materials. Recent developments in design and processing of synthetic scaffolding systems has allowed the replication of the bone's desirable biological activity in easy to fabricate polymeric materials with nano-scale features exposed on the surface. The biological response to these new tissue-engineering scaffold materials oftentimes exceeds that seen on scaffolds produced using biological materials.

Properties of interlayer for organic photovoltaics 有机光伏器件中的界面特性
Tzung-Han Lai, Sai-Wing Tsang, Jesse R. Manders, Song Chen, Franky So
Interfacial materials play an important role in determining the efficiency of an organic photovoltaic (OPV) cell. They are not only responsible for establishing ohmic contact, but also determining different device parameters such as the internal electric field, the film morphology, and the carrier recombination rate which are important to the device performance. Here, we will present the material properties and requirements for these interlayers used in high efficiency OPV cells. This paper aims to reveal the different roles of interlayers, introduce techniques for characterizing their properties, and provide an insight into the future development of novel interlayers for high efficiency organic photovoltaic cells.

Recent advances in graphene quantum dots for sensing 用于传感器中石墨烯量子点的最新进展
Hanjun Sun, Li Wu, Weili Wei, Xiaogang Qu
Graphene quantum dots (GQDs) are a kind of 0D material with characteristics derived from both graphene and carbon dots (CDs). Combining the structure of graphene with the quantum confinement and edge effects of CDs, GQDs possess unique properties. In this review, we focus on the application of GQDs in electronic, photoluminescence, electrochemical and electrochemiluminescence sensor fabrication, and address the advantages of GQDs on physical analysis, chemical analysis and bioanalysis. We have summarized different techniques and given future perspectives for developing smart sensing based on GQDs.

Radiation damage tolerant nanomaterials 纳米材料的放射性损坏容忍度
I.J. Beyerlein, A. Caro, M.J. Demkowicz, N.A. Mara, A. Misra, B.P. Uberuaga
Designing a material from the atomic level to achieve a tailored response in extreme conditions is a grand challenge in materials research. Nanostructured metals and composites provide a path to this goal because they contain interfaces that attract, absorb and annihilate point and line defects. These interfaces recover and control defects produced in materials subjected to extremes of displacement damage, impurity implantation, stress and temperature. Controlling radiation-induced-defects via interfaces is shown to be the key factor in reducing the damage and imparting stability in certain nanomaterials under conditions where bulk materials exhibit void swelling and/or embrittlement. We review the recovery of radiation-induced point defects at free surfaces and grain boundaries and stabilization of helium bubbles at interphase boundaries and present an approach for processing bulk nanocomposites containing interfaces that are stable under irradiation.
