Status of Designs of Lunar Surface Vehicles [PDF]

open access: yes
This report summarizes the activities of the various organizations that have been giving some thought and design effort to producing a lunar surface traversing vehicle. It is a state-of-the-art rather than a technical report.

A critical role of heterotrophic bacteria in early diagenesis of carbonates through exopolymer degradation and calcium release

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Exopolymeric substances (EPS) produced in the photic zone and surface sediments sequester calcium. Below the sediment surface, heterotrophic bacteria degrade EPS, releasing calcium resulting in carbonate precipitation. This process, which continues for millennia deep in the core, is an important sink for atmospheric carbon dioxide.

Uncovering the Key Factors Influencing Phytochemical and Phytopharmacological Properties During Medicinal Plant Processing

open access: yeseFood, Volume 7, Issue 1, February 2026.
From farm to pharma, this review details the engineering of quality in medicinal plants through a science‐driven approach: it first elucidates how genetic and environmental factors inscribe the plant's phytochemical and phytopharmacological profile before harvest, and then dissects the postharvest techniques and technologies—chemical and thermal pre ...

Assessment of Odor Removal in Rigid Polypropylene Waste: Comprehensive Characterization and Washing Comparison

open access: yesGlobal Challenges, Volume 10, Issue 2, February 2026.
This study examines how washing modifies odors in post‐consumer polypropylene plastics. Different washing conditions are compared by using sensory panels and advanced chemical analysis. Hot and detergent‐based washing removes key odor‐causing compounds, replacing moldy notes with cleaner, soapy impressions.
