Selenium is an important element for human’s health, small size is very helpful for Se nanoparticles to be absorbed by human's body. Here, we present a facile approach to fabrication of small selenium nanoparticles (Nano-Se) as well as nanorods by dissolving sodium selenite (Na2SeO3) in glycerin and using glucose as the reduction agent. The as-prepared selenium nanoparticles have been characterized by X-ray diffraction (XRD), UV-Vis absorption spectroscopy and high resolution transmission electron microscope (HRTEM). The morphology of small Se nanoparticles and nanorods have been demonstrated in the TEM images. A small amount of 3-mercaptoproprionic acid (MPA) and glycerin play a key role on controlling the particle size and stabilize the dispersion of Nano-Se in the glycerin solution. In this way, we obtained very small and uniform Se nanoparticles; whose size ranges from 2 to 6 nm. This dimension is much smaller than the best value (>20 nm) ever reported in the literatures. Strong quantum confinement effect has been observed upon the size-dependent optical spectrum of these Se nanoparticles. © 2017, The Author(s).

Hydroxyapatite (HAP), similar to inorganic phase in bones, shows good biocompatibility and bioactivity as bone defect repairing material. Recently, nanoscaled HAP shows the special properties differing from bulk HAP in physics, chemistry and biology. This paper demonstrates that HAP nanoparticle (nHAP) possesses the ability for inhibiting cancer cell growth in vitro and in vivo. In vitro, after treatment with nHAP for 3 days, proliferation of human cancer cells are inhibited by more than 65% and by less than 30% for human normal cells. In vivo, injection of nHAP in transplanted tumor results in significant reduction (about 50%) of tumor size. The anticancer effect of nHAP is mainly attributed to high amount by endocytosis in cancer cells and inhibition on protein synthesis in cells. The abundant nHAP internalized in cancer cells around endoplasmic reticulum may inhibit the protein synthesis by decreasing the binding of mRNA to ribosome due to its high adsorption capacity for ribosome and arrest cell cycle in G0/G1 phase. nHAP shows no ROS-involved cytotoxicity and low cytotoxicity to normal cells. These results strongly suggest that nHAP can inhibit cancer cell proliferation and have a potential application in cancer treatment.

Nb 2O 5 and Nb-Co doped 0.85BaTiO 3-0. 15Bi(Mg 1/2Ti 1/2)O 3 (0.85BT-0.15BMT) ceramics were investigated. From XRD patterns, undesired phase was observed when the (Nb 2O 5/Nb-Co) doping levels exceed 3 wt.%/2 wt.%, giving rise to the deteriorate dielectric constant. The 0.85BT-0.15BMT ceramics doped with 2 wt.%Nb 2O 5 was found to possess a moderate dielectric constant (ε ∼ 1000) and low dielectric loss (tan δ = 0.9%) at room temperature and 1 kHz, showing flat dielectric behavior over the temperature range from -55 to 155°C. It was found that the formation of core-shell structure in the BT based ceramics is controlled by the doping sequence of Nb- and Bi-oxides. © 2011 Elsevier Ltd and Techna Group S.r.l.

A scheme for predicting the effective permeability of composites containing flaky inclusions with various spatial distributions based on equivalent parameters of homogeneous comparison materials is proposed. This scheme leads to completely explicit formulas for the effective permeability in terms of microstructural characteristics that characterize the shape, concentration, distribution, and orientation of the inclusions. This scheme can also retrieve the intrinsic permeability of any ellipsoidal inclusions from the measured effective permeability of composites. The intrinsic permeability of flaky and crumb-like carbonyl iron powders obtained from different concentrations is almost identical, and the predicted effective permeability of composites containing random and oriented flaky inclusions based on the numerical results agree well with the experimental data. © 2013 Elsevier B.V.

A scheme is proposed for predicting the electromagnetic shielding properties of multilayered composites containing multiple inclusions of diverse shapes, volume concentrations, and spatial distributions based on homogeneous comparison materials and the plane-wave shielding theory. This scheme leads to completely explicit formulas for the shielding effectiveness and reflected loss of multilayered composites in terms of microstructural parameters that characterize the shape, distribution, and orientation of the inclusions. The predicted shielding effectiveness and reflected loss of single layer composite containing randomly oriented and distributed flaky silver-coated carbonyl-iron particles and two-layer composite containing randomly oriented and distributed nickel-plated short carbon fibers agree well with the experimental data. © 2013 Elsevier B.V.

The connections between the thermoelectric modules are crucial importance for the performance of the thermoelectric power system. Many studies have been done to improve the output of thermoelectric system, but very little specific to the connections between the modules. A mathematical model of a module has been established, and based on this model, the performance of two systems composed of 6 pieces of thermoelectric modules, one in series connection and the other in parallel connection, is simulated with MATLAB software and then compared. The results can be used as reference for the design and prediction of thermoelectric system. © (2013) Trans Tech Publications, Switzerland.

This review presents studies and investigations of the use of gold catalysts in environmental applications, from the oxidation of CO and volatile organic compounds (VOCs) in environmental technologies to the production of hydrogen, a non-polluting energy source, in the water-gas shift (WGS) reaction. It summarizes a variety of results, from the discovery made by Haruta et al. about the catalytic behaviour of gold in CO oxidation, to the use of gold-based catalysts in environmental remediation, by the catalytic removal of different types of VOC using a wide variety of oxide supports and finally to the use of this highly active noble metal in WGS applications. It also discusses gold loading methods, comparing them in terms of simplicity, efficiency and the resultant particle size and dispersion of Au over various supports. The application of different types of supporting materials is also presented, with a critical discussion of the parameters affecting the choice and use of such materials, i.e. how the support interacts with gold particles and with pollutant molecules along with the advantages a support offers to VOC oxidation and WGS reactions. It ends by highlighting the potential of gold catalyts in the future. This journal is © The Royal Society of Chemistry 2013.

Porous materials have been prepared via a single-source pathway. A one-step synthesis pathway has been developed for the design of hierarchically structured macro-mesoporous aluminosilicates with high tetrahedral aluminium content from a single molecular alkoxide precursor already containing Si-O-Al bonds (sec-BuO)2-Al-O-Si(OEt)3. The compensation of the cleavage of the intrinsic Al-O-Si linkage is successfully achieved by using highly alkaline media and the employment of reactive silica co-reactants, or aluminium selective chelating agents, leading to aluminosilicate materials with Si/Al ratios close to one and very high proportion of tetrahedral aluminium species. The macro-mesoporosity was spontaneously generated by the hydrodynamic flow of solvents released during the rapid hydrolysis and condensation processes of this double alkoxide. Secondly, recent advances in the conception of mesoporous zirconosilicate with homogeneous repartition of zirconium into the silicate structure (Si/Zr ∼ 4), achieved by the use of Zr[OSi(O sBu)3]4 molecular precursor, are presented. © 2010 Elsevier B.V.

Highly ordered TiO2 nanotube arrays prepared by electrochemical anodization gets considerable interest as a practical air purifier, since the nanotube arrays can form a TiO2 film with a porous surface and straight gas diffusion channel. Here, we investigate photocatalytic decompositions of HCHO over TiO2 and Ag/TiO2 nanotube arrays. Compared with the pure TiO2 nanotube arrays with similar thickness and geometric area, the results showed that Ag loading TiO2 nanotube arrays within a certain range could significantly improve the degradation rate of HCHO, the main product of HCHO degradation was detected to be CO2. ©2010 IEEE.
