The electrical transport properties of topological insulators Bi2Te3, Bi2Se3 and related specific structures have been investigated in this thesis. Three topics of topological insulators are systematically studied, including the electron-electron interaction in antidot nanostructured Bi2Te3 thin films, the interface e…
Selol is an oily mixture of selenitetriacylglycerides that was obtained as a semi-synthetic compound containing selenite. Selol is effective against cancerous cells and less toxic to normal cells compared with inorganic forms of selenite. However, Selol’s hydrophobicity hinders its administration in vivo . Therefore,…
In this paper, crystal of EuxCa1-xFeyMn1-yO3 (1/4 x 1/2, 1/4 y 1/2) has been synthesized with sol-gel method, in which gel is sintered in 750 C with muffle furnace and then grounded into powders. The structure of the synthesized EuxCa1-xFeyMn1-yO3 has been studied using X-ray powder diffraction and the results reveal…
The front electrode of a solar cell must form an ohmic contact through the etching of the antireflection coating layer of a Si-wafer and glass frit helps the formation of an ohmic contact in the materials of the front electrode of a solar cell. Some studies have reported on the sintering mechanism of glass frit at the…

The impressive history of hardmetals starts with the Schröter Patent and is then followed by the first hardmetal company, Krupp-WIDIA. Metallwerk Plansee has also played an important part in the search of drawing dies for tungsten wires and later as one of the important hardmetal manufacturers besides Kennametal in US…
In the present era synthesis of nano-material with specific size and morphology has gained importance due to its use in various fields. Zinc oxide is n-type semiconductor and has direct wide band gap of 3.37ev and large exciton binding energy of 60 mev at room temperature 1,2 . It is used in gas sensors, near UV emiss…
In past editions of the handbook, this chapter has primarily addressed issues as they pertained to Section III of the ASME B&PV Code. In particular, it has addressed issues concerning the seismic response of nuclear facilities. Currently, many other facilities covered by the ASME B&PV Code have had to address these sa…
The complex [Eu(L)3(bipy)] (where L = 2'-hydroxy-4'-methoxyacetophenone, bipy = 2,2'-bipyridine) was synthesized and characterized by elemental analysis, energy dispersive X-ray spectroscopy, 1 H NMR spectroscopy, infra red spectroscopy, TGA/DTA, scanning electron microscopy and the excitation as well as emission spec…
The methods of synthesis and characterization of the optical properties of gold nanocages produced by templated galvanic exchange of silver nanocubes is reported. The potential applications of gold nanocages with various environmental and surface conditions were investigated based on the ability to tune the localized…

Plastics Engineering is the official publication of the Society of Plastics Engineers (SPE). We provide plastics professionals with a wealth of information about machinery, technological advances, materials innovations, sustainability, and more.
Significance and Use 4.1 The absorbed dose is a more meaningful parameter than exposure for use in relating the effects of radiation on materials. It expresses the energy absorbed by the irradiated material per unit mass, whereas exposure is related to th
Removal of endotoxins from recombinant proteins is a critical and challenging step in the preparation of intravenous therapeutics, because of their potent biological activities causing pyrogenic and shock reactions. However, the interaction between protein and endotoxin makes it more complicated to remove endotoxin fr…
Ultrafast optical response of organic metal (TMTTF)2AsF6 induced by 1.5 cycle (7 fs) infrared pulse was investigated. Intense coherent oscillation of correlated charge (18 fs) grows in the time scale of 50 fs, reflecting the spontaneous-formation of the electronic coherence before the electronic thermalization.

Maspin is a member of the serine protease inhibitor/non-inhibitor superfamily (serpin), and it is implicated in inhibition of tumor invasion, cell migration, angiogenesis and then metastasis, promotion of apoptosis, and cell adhesion. The role of maspin is different in distinct types of tumor for site and histology. T…
With reduction of oil resource, biodegradable polymers have attracted more and more attention due to their biodegradability. Poly(L-lactic acid) (PLLA) is one of the most important biodegradable polymers and have been used in more and more field such as materials 1 , medicine 2 , chemistry 3 , etc. However, PLLA has s…
Hollow copper(I) oxide microspheres were prepared by using polyoxyethylene (9) nonylphenyl ether (PONPE-9) as a shape controlling agent. Copper(II) sulphate and ascorbic acid were used as the starting and reducing agents, respectively. The reaction was conducted under sonication without rigid templates at a controlled…
Ultrafast electron diffraction is used to probe the photo-induced structural dynamics of single crystal (EDO-TTF)2PF6 with femtosecond time resolution. Structure factor phases at key time points are solved ab initio using the charge-flipping method.
