Summary: Using a diffusion Monte Carlo technique, the phase diagrams of 4He and H2 adsorbed on a (5,5) carbon nanotube were calculated. Both species undergo first-order solid-solid phase transitions with increasing adsorbate density in a single monolayer. The lowest-density solid phase of 4He exhibits supersolid behavior, while the lowest-density solid phase of H2 is normal. The nature of the second layer is also different for 4He and H2, with 4He forming a liquid layer and H2 forming a solid layer at their lowest stable densities.

Summary: Low dimensional fermionic quantum systems have attracted great interest due to their unique physical phenomena. We have successfully confined He-3 on a carbon nanotube to form a 2-dimensional Fermi system and observed a quantum phase transition from 1/3 solid to an unknown, soft, and mobile solid phase.

Summary: This study investigates the impact of orientation-position coupled interaction in a one-dimensional chain model on heat conduction, finding that the system's thermal conductivity is affected by the orientation-position coupling effect at low temperatures, while at higher temperatures, the system undergoes a transition from solid-like to fluid-like behavior.

Summary: This study investigated the effects of partially substituting soybean meal in the diet with slow-release urea (SRU) on the lactation performance, heat shock signal molecules, and environmental sustainability of heat-stressed lactating cows in the middle stage of lactation. The results showed that dietary supplementation with SRU increased milk yield and rumen fermentation, while reducing heat shock molecules in dairy cows.

Summary: Isobaric heat capacity data for supercritical mixtures of methane and propane were measured and compared with three models, showing that the Peng-Robinson EOS best describes the experimental results. The inaccuracies in other models were attributed to different factors, such as the failure of the SAFT-gamma Mie EOS to predict ideal gas heat capacity accurately at cryogenic temperatures.

Summary: The study explores the impact of coal pore characteristics on methane adsorption heat, emphasizing the significant role of micropores in determining the methane adsorption heat. Results suggest that mesopores contribute the most to the specific surface area and pore volume of the five coal samples.

Summary: The heat capacity of 3He atoms dissolved in a submonolayer 4He film has been measured. The measured heat capacity suggests that the 3He atoms can move at higher areal densities. At higher densities, the heat capacity is proportional to T^2 and depends on the number of 3He atoms, indicating anomalous behavior different from a two-dimensional Fermi fluid. The possibility of fluidity within the domain walls and the presence of a one-dimensional Fermi fluid or Dirac fermions are suggested as explanations.

Summary: This paper analyzes the capacity region of a two-user multiple-access relay channel with side information known at one encoder. By transmitting two-layer individual descriptions of side information to the relay and destination, and using different coding and decoding schemes, transmission rates can be increased. Extending the inner bound to the Gaussian version can be used to study coverage area and energy efficiency.

Summary: Measurements of heat capacities for pure gases and mixtures at different temperatures and pressures showed that the SAFT-? Mie EOS can adequately describe most data above the cricondenbar, but none of the models provide reliable predictions near the critical region.

Summary: In this study, an optimized porous anatase TiO2 one-dimensional nanotube bundle nanomaterial, prepared through a simple hydrothermal process with post calcination treatment, was investigated. The material exhibited excellent electrochemical properties, including a lithium storage capability of 181 mA hr g(-1) at 0.2C rate, a high rate performance of 70 mA hr g(-1) at 20C, an excellent cyclability of 117 mA hr g(-1) with a capacity retention of 93% at 1C after 100 cycles, and 84 mA hr g(-1) at 10C after 1,000 cycles. These properties can be attributed to the anatase crystal phase, one-dimensional nanostructure, and porous framework, which provide a large surface area and efficient electrode/electrolyte contact area, as well as a fast ion/electron diffusion pathway.

Summary: The study presents a metal electronic-state manipulation approach to construct a pair of isostructural Fe-MOFs with different Fe[II] or Fe[III] oxidation states on the Fe centers, showing mixed-valent Fe[II]/Fe[III] centers in one and sole Fe[III] centers in the other. The Fe[II] presence results in stronger Fe[II]-C2H2 interactions, playing a key role in C2H2/CO2 separation, as evidenced by adsorption isotherms and calculations as well as breakthrough experiments.

Summary: A one-dimensional molten-metal-based bubble-column reactor (MMBCR) model coupled with heat transfer and axial dispersion was developed for non-oxidative CH4 py-rolysis to produce low-carbon H2. The model includes mass, momentum, and energy balances, as well as reaction kinetics and hydro-dynamic parameters. The experimental results show that the model agrees well with the data and can be used for designing industrial-scale reactors and optimizing operating conditions.

Summary: The analysis showed that MWCNTs enhance fracture toughness by deflecting crack paths, but the higher concentration of MWCNTs leads to a reduction in composite porosity. The study also found that MWCNT addition below 0.5 wt.% does not significantly increase fracture toughness due to the competing factors.
