Microwave local heating was used to join silicon nitride. Glass was placed at the joint between two silicon nitride pipes and a silicon carbide susceptor was placed around the joint. The susceptor was locally heated by absorbing the microwave radiation. On heating to 1500°C, the glass melted and filled the space betwe…
CoFe/MgO nanocomposites have been prepared from single-source inorganic layered double hydroxide (LDH) precursors via a H(2) gas-phase reduction; the metal composition can be freely manipulated by tailoring the molecular composition of the LDH precursors.
The structural characteristics of amorphous silicas obtained from aqueous solutions of sodium silicate and serpentinite and kaolin minerals were studied by X-ray diffraction and differential thermal analysis. Siloxane groups of amorphous SiO 2 were found to contain Si-O bonds different in saturation.
The radiation vulcanization of natural rubber latex (NRL) has been carried out with 150 keV electrons beam with the presence of carbon nanotubes. The NRL/CNTs were prepared by using solving casting method by dispersing carbon nanotubes in a polymer solution and subsequently evaporating the solvent. The load of the car…
Bluish green-emitting Eu 2 + -doped barium silicate ( Ba 2 Si 3 O 8 : Eu 2 + ) phosphor was synthesized via a conventional solid-state reaction chemistry, and Eu concentration and firing temperature were optimized toward its highest luminescent efficiency. Ba 2 Si 3 O 8 : Eu 2 + phosphor could be excited under near-UV…
In Indonesia, shrimp industries produce solid waste in the form of the head, tail, and skin. These material can be further processed into chitosan that can be used as plastic (chitosan edible film). The chitosan film tends to be brittle. One way to increase the flexibility of plastic chitosan is by adding additional i…
Summary of Biomimetic Smart Nano-scale Interfacial Materials Living Organisms with Special Surface Performance Wettability of the Solid Surface Biomimic Superhydrophobic Surface Smart Nanoscale Interfacial Materials with Special Wettability Conclusion and Prospect.
Esta tesis se centra en el estudio de medios quirales mediante polarimetria de amtriz de Mueller. Opticamente los medios quirales se caracterizan por tener actividad optica, que se manifiesta en procesos dispersivos con la birefringencia circular o en procesos de absorcion mediante el cicroismo circular. Nuestro ambit…
We newly synthesized well-crystallized hydrotalcite-supported copper nanoparticles, denoted as Cu/HT(c), which acted as a highly efficient heterogeneous catalyst for oxidant-free lactonization of various diols under liquid-phase conditions.The Cu/HT(c) catalyst could be recovered by simple filtration and reused withou…
This paper presents a study on the air permeability of socks manufactured using the yarns of new kinds of fibres, such as soybean, bamboo, cotton/seacells and bamboo/flax. The air permeability of plain pure knits and plated knits of textured polyamide (PA) and elastane (Lycra) wrapped with textured polyamide threads w…

High solid content nanocomposites based on poly(methyl methacrylate-co-butyl acrylate)/nanosilica was synthesized via miniemulsion polymerization in a semi-continuous operation. Oleic acid was used to act as a coupling agent between silica surfaces and polymer. Latexes with solid content of 42% were obtained, containi…
The degradation of the solid oxide fuel cell cathode material with respect to the oxygen exchange kinetics in - and -containing atmospheres has been investigated at . The material exhibits excellent stability in dry atmosphere over 1000 h. No appreciable degradation has been observed after exposure to a -rich atmosphe…
The syntheses of four new ditopic ligands (L1-4), based on N,N-functionalised 4-aminomethylpyridine, was achieved via a reductive amination methodology. The ligands react with fac-[Re(CO)(3)(di-imine)(MeCN)](OTf) to give the mixed-ligand species fac-[Re(CO)(3)(di-imine)(L1-4)](OTf). X-Ray crystallography has been used…
We study dilute solutions of poly(2,3-diphenyl phenylene vinylene) with hexyl (DP6-PPV) and decyl (DP10-PPV) side chains in two solvents, chloroform and toluene. For this purpose, atomistic and coarse-grained models are parametrized using quantum-chemical calculations and structure-based coarse-graining, respectively.…
The nanometric organization of MOx (M = Co, Zn, Ni) domains partially embedded inside the mesoporous silica walls but accessible to the pore voids, which is achieved through a simple one-pot surfactant-assisted procedure, define optimal anchors for the nucleation and growth of gold nanoparticles, which in turn favours…
Several shapes of Eu2+ doped strontium aluminate have been simply obtained by hydrolysis of Sr2+ and Al3+ in hydrothermal and solvothermal systems under mild conditions. The influence of reaction conditions on the formation of the samples has been considered. Flower-like nanoparticles are synthesized in glycol, when t…
A coarse-grained simulation model for a third generation liquid crystalline dendrimer (LCDr) is presented. It allows, for the first time, for a successful molecular simulation study of a relation between the shape of a polyphilic macromolecular mesogen and the symmetry of a macroscopic phase. The model dendrimer consi…
Imidazolium-modified carbon nanohorn-based hybrid materials have been prepared and characterized by complementary spectroscopic, thermal and microscopy techniques, while the counter-anion of the positively charged imidazolium fragment has been identified by electron dispersive X-ray analysis. In particular, oxidized c…
We demonstrate that van der Waals interactions can be used to self-assemble a small, controlled number of magnetic nanoparticles onto metallic and semiconducting carbon nanotubes. We study the effect of the sequential grafting on the room temperature transport properties of carbon-nanotube electronic devices containin…
