The Ruddlesden-Popper (RP) series of iridates (Srn+1IrnO3n+1) have been the subject of much recent attention due to the anticipation of emergent physics arising from the cooperative action of spin-orbit (SO) driven band splitting and Coulomb interactions[1-3]. However an ongoing debate over the role of correlations in…
Nickel and graphite are selected as conductive powders. Water-based adhesive are selected as coating. Electromagnetic shielding textiles were prepared with coating method. In order to improve the shielding effectiveness of textiles, multilayer compositing is used. The surface resistivity, coating amount, electromagnet…
Volume is indexed by Thomson Reuters CPCI-S (WoS).The collection includes selected, peer reviewed papers from the 2013 International Conference on Insulating Materials, Material Application and Electrical Engineering (MAEE2013), March 16-17, 2013, Changsha. The papers are grouped as follows: Chapter 1: Research on Mat…
Kinetic energy transfer from an above failed floor slab to an impacted floor slab is theoretically analyzed for two extreme impact possibilities, namely fully plastic impact and fully rigid impact, and the influence of a ratio of the failed slab’s mass to the impacted slab’s mass on the kinetic energy transfer is disc…
Abstract (Bu4N)8 [Ag6 (γ‐H2SiW10O36)2] ·5H2O is synthesized by reaction of (Bu4N)4H4 [γ‐SiW10O36] with AgOAc using dimethylphenylsilane as a two‐electron reductant in acetone (20 °C, 3 h, 80% yield).
Chitosan, an amino-polysaccharide obtained by alkaline deacetylation of chitin, is a natural and abundant polymer that is considered as an attractive candidate of biomaterial (Miyazaki et al., 1981; Madihally and Matthew, 1999). In dentistry, chitin-chitosan is applied as a dressing for oral mucous wound and a tampon…

Structural and electrophysical studies of thin amorphous and polycrystalline films of Gd–Fe system just after evaporation as well as after 3 years ageing were carried out. The high time stability of these materials has been established.
Soot particles accumulated in a DPF should be removed after a certain service time due to high pressure drop. The most common method is oxygen active regeneration which sometimes DPF cracking or melting. In this study, the authors aim to investigate the low temperature regeneration with hydrogen, which could prolong t…
고분자 입자에 그래핀이 코팅된 복합체를 제조하고 구조 및 형태변화를 통한 그래핀의 새로운 응용 가능성이 제기되고 있다. 그래핀이 표면에 흡착된 폴리스티렌 복합입자의 물성제어를 위해서, 물 분산매 하에 혼합방법과 혼합순서를 달리하여 흡착반응 시간과 혼합물 내의 순간적인 상대농도 차이를 조사하였다. 유화중합으로 중합된 폴리스티렌 입자에 폴리에틸렌이민을 흡착시켜 표면에 양전하를 갖게 만든 고분자 입자와, 흑연의 화학적 박리법으로 표면에 음전하를 갖도록 제조된 그래핀 산화물과의 서로 반대되는 전하를 갖는 두 입자의 흡착을 유도한 결과 흡착반응 시간이 길수록, 순간 상대 농…

Aluminum doped zinc oxide (AZO) is a transparent conducting oxide (TCO) with oxygen vacancy mediated carrier density and mobility. Due to low oxygen self-diffusivity, the influence of thermal reducing treatments is strongly dependent on grain size. Electrical resistivity and Seebeck coefficient measurements suggest th…
HCl-doped polyaniline (HCl-PANI) powder is synthesized by using a chemical polymerization procedure. Then Ag nanoparticles are deposited on the HCl-PANI at room temperature by RF sputtering. After this process, the nanocomposite is obtained by the chemical and physical combinative method. The nominal Ag content in the…
The effect of phase transition in catalyst nanoparticles due to increasing growth temperatures and its effect over the morphology and field emission of carbon nanotubes (CNT) films is reported here. Thin Fe film coated Si substrates are used to obtain Fe nanoparticles under hydrogen and argon plasma treatment. For thi…
본 연구에서는 poly(ethylene terephthalate)(PET) 필름을 기재로 하여 분산코팅에 의해 형성된 poly(vinylidene fluoride)(PVDF)와 poly(methyl methacrylate)(PMMA) 블렌드 코팅의 표면 특성을 관찰하였다. 분산코팅의 특성상 저온에서 형성된 블렌드 코팅은 PVDF 입자의 형태와 결정구조가 그대로 유지되었으나 $120^{\circ}C$ 이상의 코팅온도에서 형성된 코팅의 경우 블렌드에 포함되어 있는 PVDF의 양에 따라 다양한 표면 특성을 나타내었다. 블렌드 중 PVDF의 양이 80 wt% 이상인 경우…
Graphene and Graphene oxide have intense interest in fields such as physics, chemistry, and materials science, among others. They are the promising material for solving the current limitation that organics have barely luminescence. We observed variation of photoluminescence on graphene oxide based solution with Gold n…
A new, direct, simple and high yield solution phase synthesis for preparing narrow-sized silver nanoparticles by chemical reduction in aqueous solution of AgNO 3 in the presence of incorporated Sn particles in methyltrimethoxysilane (MTMS) at room temperature is reported. The resulting MTMS-silver nanoparticles were c…
Every day use of appliances relies mostly in lithium-ion batteries to satisfy their energy requirements. However, the materials utilized and their lower power densities limit these batteries' desirability. An alternative to batteries is the supercapacitors, which are capable of storing energy in the electrical double…
Vibration resulting from high-velocity projectiles impacting a structure was simulated at multiple scales. Local impact simulations were performed to predict the material deformation and penetration phenomena at the location of impact. The resulting penetration behavior of a steel panel was analyzed for various projec…
A simplified nonincremental interaction law is used describing the nonlinear elastic-inelastic behavior of FCC polycrystals proposed recently (Abdul-Latif and Radi, 2010, “Modeling of the Grain Shape Effect on the Elastic-Inelastic Behavior of Polycrystals with Self-Consistent Scheme,” ASME J. Eng. Mater. Technol., 13…
