The optical spectrum band positions and EPR parameters (g factors g//, g^ and hyperfine structure constants A// and A^) for VO2+ in Na3C6H5O7·2H2O powders are calculated from compl- ete diagonalization method and perturbation theory method. The theoretical results from both me- thods are in good agreement with the exp…
Density and ultrasonic velocity measurements are carried out for substituted -2,3-dihydroquinazolin-4(1H)-ones in 70% DMF-Water at T= 303K. The experimental values are used to calculate adiabatic compressibility, apparent molal volume, apparent molal compressibility and solvation number. These acoustical parameters ob…
This paper proposes a new method for forming microcarries from bacterial cellulose (BC). BC, which is produced by specific bacteria, is a hydrogel composed of a three dimensional network structure formed by cellulose nanofibers. BC as an ECM-like nanofibrous material exhibits an excellent environment for cellular adhe…
Cyanobacterium has ion channels on its cell membrane, and they work to protect the cell from osmotic stress. Since functions of some ion channels relate to intracellular pressure changes, we aim to develop the mechanical characteristics measurement system of Synechocystis sp. PCC 6803, which is one of the most commonl…
Ultrasonic velocity and density of substituted aminopyrimidine in 70% DMF solvent have been measured at300Kanddifferent concentration. The experimental data is used to calculate adiabatic compressibility (βS), specific acoustic impedance (Z) and intermolecular free length (Lf). The acoustical parameters are explained…
A novel function for FANCJ helicase in microsatellite stabilization during replication stress.Noncanonical DNA structure-forming sequences, such as hairpin structures, stall replication forks in vivo, expand or contract during DNA replication, and colocalize with chromosome fragile sites.Since the frequency of hairpin…
It is known that the thermal resistance at a solid-liquid interface is changeable when nanoparticles adhere to a heat transfer surface. This is partially because the liquid density around nanoparticles is changed by the nanoparticle-liquid interaction. In the present study, we conducted nonequilibrium molecular dynami…
Проведены исследования структуры монокристаллов халькогенидов железа Fe1+ δTe1- xSx ( х = 0; 0.09; 0.1) методами растровой, просвечивающей и просвечивающей растровой электронной микроскопии, а также рентгеноструктурный анализ образца с х = 0. В образцах Fe1+ δTe обнаружено разупорядочение позиции атома Te, что может б…
We have succeeded in generation of micro-vortex ring using cavitation phenomena and high speed micro-bubbles laden jet in microfluidic enviromnent. First of all, the relatively large mother bubble is prepared at the tip of the probe by electrically driven bubble generator. As soon as after the mother bubble is collaps…
Ice adhesion to a cooling solid surface often causes a major accident, while, recently, stronger adhesion force of ice is positively used to fix a workpiece. Therefore, it is necessary to control an ice adhesion force to the cooling solid surface. One of the authors clarified that a thin film made from a silane-couple…
Solid oxide fuel cells (SOFC) have much promise as efficient devices for the direct conversion of the energy stored in chemical fuels into electricity. The development of highly robust SOFC that can operate on a range of fuels, however, requires improvement in the electrodes, especially the anode, where nanoscale engi…

The density (ρ), viscosity (η) and ultrasonic speed (U) (2MHz) of 1, 4-dioxane solutions of symmetric double Schiff bases (SB-1 and SB-2) were determined at 303.15, 308.15 and 313.15K. Various acoustical parameters such as specific acoustical impedance (Z), isentropic compressibility ( k s), Rao’s molar sound function…

Hlavním cílem diplomové práce bylo srovnání dvou metod příprav V-katalyzátorů, a to metody impregnace a molekulární disperze. Pozornost byla zaměřena na analýzu distribuce VOx částic na alumina a SBA-15 nosičích plynoucí z obou typů příprav V-katalyzátorů a dále pak na aktivitu/selektivitu těchto částic v ODH etanu. P…
Although numerous robots have been developed inspired by animal locomotion, they could not reproduce adaptive and resilient behavior of real animals. To tackle this problem, we adopted ophiuroids as our model. In our previous work, we focused on the locomotion of an ophiuroid whose arms were shortened or removed to in…
In recent years, biological fields such as regenerative medicine require continuous non-invasive transportation of large population of cell in culture media. Conventional methods achieved this purpose by using different kinds of pump. However, no systems have developed which are capable of investigating the invasivene…
Actually platinum is still the most common metal catalyst in both anode and cathode fuel cell. In spite of the many attempts made in the last decade to develop non-Pt based catalysts for low temperature air cathodes, Pt remains the catalyst of choice, at least for acid based fuel cells. The situation in alkaline elect…
We observed the condensation process of submicron-scale droplets on silicon (100) surface by using environmental scanning electron microscope. We found that the condensation growth of a submicron-sized droplet is classified into two modes. In the first mode, the contact angle is smaller than the macroscopic contact an…
Phase field model is known to be very powerful in describing the complex pattern formation of the interface in non-equilibrium state, such as growth of dendritic crystals. In this study, the effects of anisotropy of the crystals on Mullins-Sekerka instability in growth of solid-liquid interface were investigated numer…
