Extraction and Analytical Standardisation of DMPBD and Related Phenylbutenoids From Cassumunar Ginger: A Systematic Review and Quantitative Evidence Map

open access: yesPhytochemicals in Food and Medicine, Volume 1, Issue 4, December 2026.
Across 15 studies, extraction technologies produced nonequivalent DMPBD‐related outcomes, preventing a universal method ranking. Reliable comparison requires authenticated plant material, validated compound‐specific quantification, plant‐normalised DMPBD yield, mass balance and transparent resource‐use reporting.

Toward Integrated Solar Fuel Platforms: Advances in Oxide‐Based Photoelectrochemical Water Splitting and CO2 Reduction

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 11, November 2026.
Comprehensive review of advances in oxide‑based PEC materials for water splitting and CO2 reduction. ABSTRACT Photoelectrochemical (PEC) solar‑fuel production has emerged as a compelling route to carbon‑neutral energy. Yet, its practical deployment remains limited by the intrinsic constraints of metal‑oxide semiconductors, restricted visible‑light ...

Bioeconomy, sustainability, and digital technologies in Haematococcus lacustris biomass and astaxanthin production: advances and outlook

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 6, Page 2203-2216, November/December 2026.
Abstract Astaxanthin is a carotenoid with strong antioxidant properties, used in research on cancer treatment, ocular injuries, and neurological disorders. When produced by the microalgae Haematococcus lacustris, its antioxidant potential is even higher than that of the synthetic molecule, making it particularly attractive for pharmaceutical and ...
