N conjugated polymer thin films represent a promising material for applications such as sensing or organic photovoltaics due to their enhanced interface and semi-conducting properties. While most researchers focus their studies on either elaborated chemistry or time and energy-consuming nano-imprinting methods, we her…
L temperature hydrothermal synthesis of different ZnO nanostructures with rational control over their morphology and size is important for a wide range of sensing applications. ZnO nanostructures with different dimensionalities have been synthesized through low temperature hydrothermal techniques. One dimensional ZnO…
D containing rigid conjugated backbones were prepared by a convergent method where the attachment of dendritic branches and the extension of phenylene-ethynylene units were alternatively manipulated on the structure of AB2 substituted diphenylacetylene. These dendrimer structures were applied for the construction of n…
A crystal of dithiolene complex with supramoelcular cation, (m-fluoroanilinium+) (dibenzo[18]crown-6)[Ni(dmit)2] exhibiting ferroelectric transition at 346 K originating from dipole inversion due to flip-flop motion of the aryl moiety in the supramolecular cation have been reported. The supramolecular cations are adva…
G an atom thick of carbon semimetal, has attracted a great deal of attention due to its new properties and promising applications which might have impact in new electronic devices, novel composite materials, innovative sensors, etc. However, graphene it is not alone, there is also hexagonal boron nitride (H-BN) a laye…
I this talk, it will be demonstrated that both dedecanethiol-passivated Ge nanowires and graphene-germanium composites can serve as excellent LIB anodes. Germanium (Ge) is considered as a high-capacity anode materials for lithium-ion batteries (LIBs) due to its high theoretical capacity of 1384 mAh/g, which is four ti…
T use of nanoporous membrane in fabrication of biosensorsof high sensitive and specificity for the detection of various analyte is currently an issue of great importance, and its success is often dictated by the size and nature of pore as well as the detection element (the specific ligand) along with choice of target…
A Si and Ge films were deposited by magnetron sputtering with a laboratory-built combinatorial sputtering system at temperature of 25, 300, 500, and 600°C. The Si and Ge thin films prepared at each deposition temperature were 15, 100, and 250 nm thick. We characterized the crystalline states and microstructures of the…
O of the most fundamental laws of nature is the alternate arrangement of cationic and anionic species in an ionic solid. Thus, it is very hard to imagine that a number of inorganic anions come close to each other unless Coulombic repulsion is eased by the presence of polar molecules. As part of our continuing research…
C nanotubes (CNTs) and graphene are considered as prime materials for nanometer-scale science and technology due to their unique and superior combination of electrical, thermal, optical and mechanical properties. This has inspired a widespread effort to develop CNTs and graphene based applications for next generation…
Cavitation occurs during the flow when local pressure drops to the saturation pressure according to the temperature of the flow. It includes both evaporation and condensation of the vapor bubbles, which occur alternately with high frequency. Cavitation can be very dangerous, especially for pumps, because it leads to b…
P cellulose nitrate (CN) and blends of cellulose nitrate and poly (caprolactone) (PCL) were electrospun to form nonwoven mats. Mixed solvent systems of tetrahydrofuran (THF) and N, N-dimethylformamide were employed. The concentrations were varied to obtain sub-micron and nanoscale fiber mats. These fiber mats were ana…
F bulk (multilayer) two-dimensional (2D) zero-gap state with massless Dirac particles was realized in an organic conductor α-(BEDT-TTF)2I3 under pressure. We have succeeded in detecting the zero-mode Landau level and its spin-split levels in this system probed by inter-layer magneto resistance. The Shubnikov-de Haas o…
본 연구는 거대고리 금속 이온 착화합물과 유도체를 이용하여 미세 다공성 구조를 가지는 분리막의 제조에 관한 것이다. 고분자와 금속이온 리간드 착물 시스템을 이용함으로써 기존의 방법들에 비해 상 전이 과정을 보다 정교하게 제어할 수 있었다. 금속염, cyclohexanedione dioxime, hydroxyphenylboronic acid와의 축합 반응을 통하여 금속 clathrochelate 착물을 얻을 수 있었다. PES, PVP, BE와 금속 clathrochelate 착물을 DMF에 녹인 후 비용매 유도 상 전이법을 통하여 유무기 혼성고분자막을 제조하였다.…
The specialists of the Iskra Scientific and Production Association in cooperation with the Perm National Research Polytechnic University have carried out a research work on utilization of solid-fuel rocket engine's fiberglass materials as raw-stuff for building materials such as concrete and foamed glass. Utilization…
T alkaline-earth iron perovskites AFeO3 (A=Ca, Sr, Ba), containing iron in a high valence state of Fe4+ (3d4), have been prepared using high-pressure apparatases to generate strongly oxidizing atmosphere. Recently, however, Hayashi et al. obtained BaFeO3 by heating easily prepared BaFeO2.5 at 200oC in flowing oxygen c…
The effect of gamma radiation on the dynamic mechanical properties of cortical bone was accessed in this study. The cortical bone samples were divided into two groups: an untreated control specimens and specimens subjected to gamma radiation sterilization. A dose of 30 kGy was used to sterilize the bone samples. Unlik…
The corrosion products which are formed after corrosion of metalic biomaterials enter into the surrounding cells and cause damage. Therefore, different surface processes are applied to the biomaterials. In this study, CoCrMo alloy was used as biomaterial and oxidized in 100% O2 gas atmosphere at 600°C and 800°C temper…
