Low-dimensional heterostructured functional materials have been widely applied in new energy materials, catalysts, et al. However, to enhance photo-response in visible light and the biocompatibility improvement are still the great challenges faced. And the dendrimers act good roles in transferring the drug and gene, and has good biocompatibility. Self-assembly on the surface of low-dimensional heterostructured functional materials with dendrimers holding-COOH groups was carried out in this paper. The characterizations of the materials were examined by SEM (scanning electron microscopy), XRD (X-ray diffraction), the Fourier-Transform Infrared (FTIR) spectra, ultraviolet-visible spectroscopy (UV-Vis) and so on. The photoconductivity response to visible light and 808 nm laser with low-power were studied based on interdigital electrodes of Au on flexible PET (polyethylene terephthalate) film substrate. The results indicated that ZnO/CuS modified with dendrimers showed good photo-response to visible light and 808 nm laser, the photo-response properties enhanced greatly by adding some small amount of grapheme oxide. Photocatalytic efficiency was examined by selecting typical organic pollutants, some good results were obtained. The external stimuli driven nanorobots for removal the organic pollutants or toxins in the living body have been developed.

The unique structures formed by β-amino acid oligomers, or β-peptide foldamers, have been studied for almost two decades, which has led to the discovery of several distinctive structures and bioactive molecules. Recently, this area of research has expanded from conventional peptide drug design to the formation of assemblies and nanomaterials by peptide self-assembly. The unique structures formed by β-peptides give rise to a set of new materials with altered properties that differ from conventional peptide-based materials; such new materials may be useful in several bio- and nanomaterial applications.

Nanocelluloses (NCs), with their remarkable characteristics, have proven to be one of the most promising “green” materials of our times and have received special attention from researchers in nanomaterials. A diversity of new functional materials with a wide range of biomedical applications has been designed based on the most desirable properties of NCs, such as biocompatibility, biodegradability, and their special physicochemical properties. In this context and under the pressure of rapid development of this field, it is imperative to synthesize the successes and the new requirements in a comprehensive review. The first part of this work provides a brief review of the characteristics of the NCs (cellulose nanocrystals—CNC, cellulose nanofibrils—CNF, and bacterial nanocellulose—BNC), as well as of the main functional materials based on NCs (hydrogels, nanogels, and nanocomposites). The second part presents an extensive review of research over the past five years on promising pharmaceutical and medical applications of nanocellulose-based materials, which have been discussed in three important areas: drug-delivery systems, materials for wound-healing applications, as well as tissue engineering. Finally, an in-depth assessment of the in vitro and in vivo cytotoxicity of NCs-based materials, as well as the challenges related to their biodegradability, is performed.

Blast Effect

Building protection on our century is very important because of the terrorist attacks. The old buildings in Europe aren’t enough strong again blast loads. Nowadays we know many different explosives and theirs effects of walls and human bodies. The detonation caused blast effect provokes building damage and fragmentation effects. The explosion caused damages, parts of bricks and fragments produce other secondary damage in other buildings and human bodies.It can’t protect the historical and old buildings by new walls and fences because of the cityscape. It needs to find new possibilities to improve the buildings resistance again blast effects. It needs a effectively thin and strong materials to reinforced the buildings walls. The new materials innovated by material science can be good solution for this project. These materials usually composites likes syntactic foams, spherical shells or carbon fields reinforced composites.

Doping remains a bottleneck in discovering novel functional materials for applications such as thermoelectrics (TE) and photovoltaics. The current computational approach to materials discovery is to identify candidates by predicting the functional properties of a pool of known materials, and hope that the candidates can be appropriately doped. What if we could "design" new materials that have the desired functionalities and doping properties? In this work, we use an approach, wherein we perform chemical replacements in a prototype structure, to realize doping by design. We hypothesize that the doping characteristics and functional performance of the prototype structure are translated to the new compounds created by chemical replacements. Discovery of new <i>n</i>-type Zintl phases is desirable for TE; however, <i>n</i>-type Zintl phases are a rarity. We demonstrate our doping design strategy by discovering 7 new, previously-unreported ABX<sub>4</sub> Zintl phases that adopt the prototypical KGaSb<sub>4</sub> structure. Among the new phases, we computationally confirm that NaAlSb<sub>4</sub>, NaGaSb<sub>4</sub> and CsInSb<sub>4</sub> are <i>n</i>-type dopable and potentially exhibit high <i>n</i>-type TE performance, even exceeding that of KGaSb<sub>4</sub>. Our structure prototyping approach offers a promising route to discover new materials with designed doping and functional properties.
