• 要約等: Efficiency at maximum power (MP) output for an engine with a passive piston without mechanical controls between two reservoirs is studied theoretically. We enclose a hard core gas partitioned by a massive piston in a temperature-controlled container and analyze the efficiency at MP under a heating and cooling protocol without controlling the pressure acting on the piston from outside. We find the following three results: (i) The efficiency at MP for a dilute gas is close to the Chambadal–Novikov–Curzon–Ahlborn (CNCA) efficiency if we can ignore the sidewall friction and the loss of energy between a gas particle and the piston, while (ii) the efficiency for a moderately dense gas becomes smaller than the CNCA efficiency even when the temperature difference of the reservoirs is small. (iii) Introducing the Onsager matrix for an engine with a passive piston, we verify that the tight coupling condition for the matrix of the dilute gas is satisfied, while that of the moderately dense gas is not satisfied because of the inevitable heat leak. We confirm the validity of these results using the molecular dynamics simulation and introducing an effective mean-field-like model which we call the stochastic mean field model.

• 要約等: An x-ray diffraction measurement and a density functional theory (DFT) calculation of the pressure-induced transformation in LiBH4 were performed. The structure of its first high pressure phase at room temperature (phase-III) was determined to be <i>I</i>4₁/<i>acd</i> structure, whose unit cell was a √ 2 ×√ 2 ×2 supercell of <i>Ama</i>2 structure proposed previously. Pressure-induced transformation from phase-III took place at 16 GPa and the structure of the second high-pressure phase was analyzed as <i>I</i>4/<i>mmm</i> structure (phase-V′), in which hydrogen atoms were disordered. However, an annealing treatment for phase-V′ under high-pressure suggested that it was a metastable phase. With the pressure elevated up to 30 GPa, the tetragonal <i>I</i>4/<i>mmm</i> structure was gradually transformed to a cubic <i>Fm</i><span style="text-decoration:overline;">3</span><i>m</i> structure, which has been reported as a stable phase of phase-V previously. The <i>P</i>-<i>T</i> diagram was examined using high-pressure/high-temperature Raman scattering, and pressure/temperature dependence of the relative ionic conductivity was observed across the phase boundaries.<br>
