Observations of composition from Pioneer Venus [PDF]
Long latitude distributions of atmospheric neutral hydrogen were derived at Venus for the period 1979 to 1980. In-situ measurements of H+, O+, O, and CO2 obtained from the ion and neutral mass spectrometers on the Pioneer Venus orbiter are combined with ...

Carbon Energy, EarlyView.This study designs a CrOx‐engineered Ni‐based catalyst enabling efficient and stable seawater electrolysis. The catalyst utilizes a dynamic interfacial barrier that selectively adsorbs OH− to repel Cl− corrosion while activating lattice oxygen‐mediated pathways.

Long-period cosmic ray variations and their altitude dependence [PDF]
Long-period variations were studied from the data of ground-based cosmic ray (CR) observations. In spite of a large value of an 2-year variation, it is more difficult to obtain its spectrum than the spectrum of a solar diurnal variation.

In Situ Methanation on Mars: A Process Concept Study on the Impact of H2/CO2 and Recycle Ratio
Chemie Ingenieur Technik, EarlyView.The rocket propellant methane can be produced on Mars by in situ resource utilization. The H2/CO2 ratio is decisive, and excess H2 is favored for providing sufficient propellant purity. The operation mode—with or without recycling of unreacted reactants—depends on the resource availability of the selected landing site. Abstract For return missions from

Density variations of meteor flux along the Earth's orbit [PDF]
No model of distribution of meteor substance is known to explain the observed diurnal and annual variations of meteor rates, if that distribution is assumed to be constant during the year.

EcoEnergy, EarlyView.The phase transition process imparts shape‐stable gels with the capability of reversible transparency modulation and temperature‐responsive heat storage and release. When applied to smart windows, this property ensures the maintenance of thermal energy within the human thermal comfort zone, thereby facilitating indoor energy conservation.
