Summary: Sustainable energy supply is a major challenge for the lunar base, and a promising solution is to utilize lunar regolith heat storage. This study proposes a dish solar thermal power system with lunar regolith heat storage and investigates its performance in a lunar circadian cycle. The system gradually decreases in output power and efficiency during the lunar day and night, with average output powers of 10.8 kW and 7.0 kW, respectively, and a high energy efficiency of 48.0%. The study reveals the potential of the proposed system to continuously and efficiently supply energy to the lunar base, providing a scheme for the future lunar base's energy supply system.

Summary: In this study, the diurnal variation of microwave thermal radiation cold spots on the lunar surface was analyzed using the data from Microwave Radiometer (MRM) on Chang'e-2 Lunar satellite. Two typical craters, Jackson and Morse, were selected to compare their diurnal radiation temperature differences. It was found that the variation of cold spots is closely related to the rock abundance distribution in newly formed craters and has a certain correlation with the (FeO + TiO2) abundance.

Summary: A solar energy storage power generation system based on ISRU was established and analyzed, with an efficient linear Fresnel collector and a thermal energy reservoir coupled with a Stirling power generator for energy production during the lunar night. Results showed that the system could produce an average power of 6.5 kW during the lunar night with 19.6% utilization efficiency of collected solar energy in the daytime.

Summary: SEPs with high mass (Z > 26) and energy similar to 1 MeV nucleon(-1) leave visible damage tracks in meteoritic materials. The density of these tracks in lunar and asteroidal samples provides critical information on planetary space weathering rates, dust grain dynamics and lifetimes, and solar particle flux history. In this study, the authors calculate the flux of track-inducing particles at 1 au based on in situ observations by NASA's ACE spacecraft and discuss the discrepancy between their rate and the observed rate in lunar samples. Further research is needed to explain this discrepancy and understand SEP track formation.

Summary: A novel Critical Time Step technique is proposed to model energy storage for a solar-dominated system, which reduces computational requirements while maintaining accuracy. By using critical times of an hour after sunrise and an hour before sunset, this technique achieves a good balance between accuracy and computational complexity. The technique is evaluated by comparing results for three weather years, showing high accuracy in predicting power and energy expansion for a grid with more than 35% solar power share.

Summary: With the growing interest in lunar exploration, the construction of a lunar base has become a focus for researchers. The extreme temperature variations on the lunar surface and the long lunar night pose challenges for the energy system of the base. This study proposes a combined heating and power system with in-situ resource utilization to reduce launch costs while ensuring sufficient power and heat output.

Summary: The study reveals that some Pacific cod in the Aleutian Islands undergo seasonal migration, with the majority migrating in mid-March from winter spawning areas to summer foraging grounds. However, a few individuals choose to stay in their capture locations, suggesting a partial migration strategy.

Summary: Restoration of temperate forests has an impact on the diurnal dynamics of land surface temperature (LST) and evapotranspiration (ET). ECOSTRESS allows for the study of these dynamics at a moderate spatial resolution. The study compared and modeled the LST and ET dynamics of forest restoration sites in Southern Ontario. The results showed that restoration sites had a higher ability to buffer temperatures in the afternoon, but were still warmer than mature forest sites.

Summary: A full diurnal measurement of stratospheric column NO2 was conducted above Los Angeles, revealing diurnal variations and the influence of urban pollution. The daytime NO2 increasing rate was found to be (1.34 +/- 0.24) x 10^14 cm^(-2) h^(-1), with observed concentrations exceeding model simulations on some afternoons due to pollution from nearby counties.

Summary: This work investigates a solar-assisted pumped thermal energy storage system which utilizes solar collectors, a heat pump, a storage system, and an organic Rankine cycle. By analyzing with a mathematical program, it was found that the optimum storage temperature is 150℃ and the optimum temperature in the evaporator of the heat pump is 75℃, resulting in a power recovery ratio of 68.48%, an organic Rankine cycle efficiency of 18.45%, and a heat pump coefficient of performance of 3.704.

Summary: A novel liquefied air energy storage (LAES) system with coupled Rankine cycle and seawater desalination is proposed to improve its round-trip efficiency by energy cascade utilization. The thermodynamic model of the coupled system is established and its technical advantages are investigated, including system energy efficiency, exergy efficiency, round-trip efficiency, and desalination. The results show significant improvement in energy efficiency, exergy efficiency, and round-trip efficiency, as well as the capability to produce a large amount of fresh water.

Summary: This research aimed to identify the extent of blue sucker habitat and species mobility in the Colorado River, Texas. Critical river reaches were identified, suitable habitats were found to be limited, and larger home ranges were presumably necessary for blue suckers to find suitable habitats.

Summary: We used stable isotope analysis to investigate differences in resource use between Guadalupe bass populations in mainstem river and tributary stream habitats. Guadalupe bass in mainstem sites had higher δ13C and δ15N values, reflecting the greater importance of algae as a basal resource and influences of urban wastewater. Documenting ecological variation in different ecosystem types is crucial for fish conservation efforts, especially for species inhabiting various stream sizes.
