Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Unraveling the symmetry of Al5C3N

open access: yesActa Crystallographica Section B, Volume 82, Issue 3, Page 299-309, June 2026.
From experimental and theoretical techniques employed in this thorough reexamination of the structure of Al5C3N, the crystal structure is better described in centrosymmetric space group P63/mmc (No. 194) rather than in the previously reported noncentrosymmetric space group P63mc (No. 186).High‐temperature ceramic compound Al5C3N belongs to the scarcely

Savannah and Boreal Biomass Burning as a Source for Cloud Condensation Nuclei

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Aerosol particles emitted in wildfires can contribute to radiative forcing via aerosol‐cloud interactions and by directly interacting with solar radiation. Wildfire emissions increase the concentration of cloud condensation nuclei (CCN) in the atmosphere and thus affect cloud properties (e.g., cloud brightness).

A study of Free Convection in A solar Chimney Model [PDF]

open access: yesEngineering and Technology Journal, 2011
A solar chimney is a hot air channel attached to a circular translucent roof opens at the periphery. The roof and the ground below it form an air collector. It enhances natural ventilation by employing air temperature difference between channal inlet and

Surface‐Driven Protocell Formation in Geologically Relevant Early Earth Environment

open access: yesChemSystemsChem, Volume 8, Issue 2, March 2026.
Illustration of a prebiotic early‐Earth environment showing cell‐like protocells (blue spheres) and other complex organic molecules (pink and green spheres) distributed across terrestrial surfaces and within subsurface niches. Volcanic landscapes and mineral‐rich substrates provide diverse geochemical settings for the assembly and evolution of ...

CFD‐Assisted Design and Prototyping of a Solar Dryer for Pomegranate Arils: From Virtual Models to Physical Implementation

open access: yesJournal of Food Process Engineering, Volume 49, Issue 3, March 2026.
CFD‐guided design of a solar dryer for pomegranate arils demonstrated effective drying under both natural and forced convection, with virtual simulations closely matching experimental results. The study highlights performance trade‐offs, uniformity challenges, and practical design insights for sustainable postharvest processing.

Analysis of Solar Chimney Power Plants Based on the Bam's Climate

open access: yesTehnički Glasnik, 2022
One of the ways to generate power from the solar energy is to use the solar chimney technology. In the present study, by examining the weather map of Iran and using GIS software for selecting the appropriate area for the power plant site, the four ...

Solar Chimney Operation Variant

open access: yesEnergies
This paper presents a solar chimney that acts as a heat accumulator. It is based on its alternating charging (melting of the phase change material—PCM) and discharging (solidification), which helps to save energy and ensures stable operation of the solar chimney.

Urban and Power Plant NOx Emissions in Sub‐Saharan Africa Inferred From TROPOMI

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Nitrogen oxides (NOx) emissions are increasing rapidly in Sub‐Saharan Africa, affecting local air quality. Outside South Africa, most hotspots are relatively small, posing a challenge for traditional top‐down inversions. We tailor an existing top‐down wind rotation and Gaussian plume fit inversion to suit the relatively small NOx hotspots for ...

Advanced Flame Retardant Strategies and Fire Performance Assessment for Safer Photovoltaics in Buildings: A Two‐Part Review

open access: yesAdvanced Functional Materials, Volume 36, Issue 16, 23 February 2026.
The integration of photovoltaic (PV) systems into building structures introduces distinct fire risks with critical implications for occupant safety. This review examines the key fire hazards associated with PV implementation and explores mitigation strategies, including flame‐retardant additives.
