Preliminary experimental results of gas recycling subsystems except carbon dioxide concentration

Oxygen concentration and separation is an essential factor for air recycling in a controlled ecological life support system (CELSS). Furthermore, if the value of the plant assimilatory quotient is not coincident with that of the animal respiratory quotient, the recovery of oxygen from the concentrated CO2 through chemical methods will become necessary to balance the gas contents in a CELSS. Therefore, oxygen concentration and separation equipment using Salcomine and O2 recovery equipment, such as Sabatier and Bosch reactors, were experimentally developed and tested

Competing Ground States of a Peierls-Hubbard Nanotube

Motivated by iodo platinum complexes assembled within a quadratic-prism lattice, [Pt(C$_2$H$_8$N$_2$)(C$_{10}$H$_8$N$_2$)I]$_4$(NO$_3$)$_8$, we investigate the ground-state properties of a Peierls-Hubbard four-legged tube. Making a group-theoretical analysis, we systematically reveal a variety of valence arrangements, including half-metallic charge-density-wave states. Quantum and thermal phase competition is numerically demonstrated with particular emphasis on doping-induced successive insulator-to-metal transitions with conductivity increasing stepwise.Comment: 6 pages, 4 figures. to be published in Europhys.

Fluid Devices by the Use of Electrohydrodynamic Effects of Water

When the high DC electric fields are applied to distilled water through needle electrodes, the jet flow with velocities up to 0.3 ms-1 is generated in bulk from the negative to positive electrodes. The flow direction and velocity can be modified by the design of electrodes and their arrangements. By controlling the flow patterns, new types of inkjet devices and liquid motor are developed. In inkjet devices, a set of electrodes consisting of short tube and needle is vertically placed in plastic tube and the distilled water so filled in the reservoir that the electrodes are completely immersed. The application of high voltages causes the vertical flow to produce a water column with free surface. The motor consists of vane wheel, cup, two sets of electrodes, and working fluid. For aqueous solutions of ethanol and glycerin, the angular velocity of motor is measured as a function of viscosity and conductivity. The high performance of motor is achieved by the solutions with viscosity of 0.85 ~ 1.7 m Pa·s and conductivity of 20 ~ 30 Sm-1. The EHD water jets have great potential in application to new fluid devices
