Platinum-based anti-cancer agents have been used for many years to treat many different types of cancer. However, the efficacy of these drugs is limited by serious side effects. One of the strategies to reduce the side effects is encapsulation of the drug in a lipid formulation. Recently, we discovered a novel method…
We developed an interesting instrument in manufacturing a biodegradable polymer-insulated cable, with a variety of new functions. By using this instrument, we manufactured a poly-l-lactic acid (PLLA)-insulated cable. We measured the basic electrical insulation characteristic of the PLLA-insulated cable, and the follow…
CO2 photoacoustic spectroscopy was employed to analyze kinetically the CO2/CH4 reaction catalyzed by 14 wt% Ni/Al2O3 and 14 wt% Ni/TiO2. The catalytic reaction was carried out in the temperature range of 673-923 K at various partial pressures of CO2 and CH4 (40 Torr total pressure) in a closed-circulating reactor syst…
Biocomposites (biodegradable composites) are obtained by blending biodegradable polymers and fillers. Since the main components are biodegradable, the composite as a whole is also expected to be biodegradable. This paper presents various biocomposites that have been elaborated with cellulose or lignocellulose fibers f…
A novel cationic, photoresponsive azobenzene derivative with the characteristic of self-assembly, 2-{4-[(E)-(4-{[11-(dodecylthio)undecyl]oxy}phenyl)diazenyl]phenoxy}-N,N,N-trimethylethanaminium bromide (1), has been synthesized. Self-assembled monolayers (SAMs) of 1 on ultrathin, transparent platinum electrodes have b…
In fabric sound research, loudness has been proven to be the primary factor determining auditory sensation while other factors have not received enough attention in relation to their significance. This study aimed to analyze the secondary sound factors that differentiate sensations of fabric sounds at given sound pres…
The reaction in water of Cu(OH)(2) with 2,2'-bipyridine (bipy) and (NH(4))(2)HPO(4) in a 4 : 4 : 2 molar ratio under an inert atmosphere leads to the formation of a tetranuclear copper(II) complex of formula {[(H(2)O)(2)Cu(4)(bipy)(4)(mu(4)-PO(4))(2)(mu(2)-OH)] x 0.5 HPO(4) x 15.5 H(2)O}, 1, with butterfly topology. T…
Assemblies of heterodimeric particles were prepared through selective coupling of two kinds of spherical silica particles of different sizes by connection with gold nanoparticles attached anisotropically to the particles.
Artificial patina layers are often used to give final appearance and also to restore damaged old copper and bronze surfaces. The main inconvenient of this process is that it frequently requires surface heating or total immersion of the metallic object in the patina solution, which is sometimes impossible to accomplish…
Sulfonic acid-incorporated-MCM-41 mesoporous materials prepared using a silane containing tetrasulfide linkages showed exceptional yields of the acetylated product in the acetylation of anisole due to their high content of strong acid sites.

Low cycle fatigue life of structural materials diminishes remarkably as functions of various parameters in high temperature water simulating LWR coolant. Such reduction was estimated by the fatigue life reduction factor (Fen) and the equations to calculate Fen were developed and have undergone revision over the past t…
Pseudomonas aeruginosa were used for extracellular biosynthesis of gold nanoparticles (Au NPs). Consequently, Au NPs were formed due to reduction of gold ion by bacterial cell supernatant of P. aeruginos ATCC 90271, P. aeruginos (2) and P. aeruginos (1). The UV‐Vis. and fluorescence spectra of the bacterial as well as…
Nanosized layered double hydroxides (LDH) were synthesized inside the mesooporous carbon (CMK-1) known as CMK-LDH nanocomposites by simple impregnation and precipitation techniques. The catalytic activity of these nanocomposites for Claisen–Schmidt condensation reactions showed remarkably high activity and selectivity…
The paper presents results on eroded mass measurements for nanofilled silicone rubber by controlled infrared laser heating, which simulates hot spot heating by dry-band arcing on wet and polluted composite insulators. Improvement in dispersion by surface treatment of the nanofillers with surfactants and by calcination…
15-Crown-5-appended metalloporphyrin causes a K(+)-driven self-organization to bind a bifunctional guest ditopically, thereby allowing the circular dichroism (CD) detection of chirality induced in the ensemble when chiral amines are employed as the guest; the chiroptical properties are discussed.
Fluorescence spectra of Nd:YVO(4) under excitation of a continuous wave (CW) diode laser and a femtosecond laser at 800nm were investigated. It was found that Nd:YVO(4) shows different upconversion and downconversion luminescencent behaviors when excited by the diode laser and the femtosecond laser. The dependence of…
We introduce a set of new interfacial energies for approximating the Euler number of level surfaces in the phase field (diffuse-interface) representation. These new formulae have simpler forms than those studied earlier in [Q. Du, C. Liu and X. Wang, Retrieving topological information for phase field models, SIAM J. A…
The solvent promoted aggregation behaviour of a meso-substituted amphiphilic corrole derivative occurs with the formation of aggregates with regular morphology, different from those obtained in the case of related porphyrin structures, opening interesting perspectives for the application of these derivatives in import…
In summer 2004 and 2006 the TOHYCO-Riderabus with supercapacitors and IPTbwas operated by the IIEECfor public transport services in Lucerne. A second generation version of a supercapacitor storage SAMdwas implemented and tested. A very important step in industrializing hybrid vehicles with SAM became fulfilled. The qu…
