Recent Advances in Catalytic Conversion of Bioethanol to 1,3‐Butadiene: Reaction Mechanism, Catalyst Design, and Process Scalability

open access: yesChemSusChem, Volume 19, Issue 1, January 2026.
Catalytic conversion of ethanol to 1,3‐butadiene (BD) can proceed via one‐step and two‐step routes. In the one‐step process, pure and metal‐modified MgO–SiO2 catalysts enable direct ethanol transformation to BD, while ZrO2‐based catalysts drive the two‐step pathway.

Mineral reconnaissance at the Highland boundary with special reference to the Loch Lomond and Aberfoyle areas [PDF]

open access: yes, 1983
Serpentinite bodies at the Highland Boundary in the Loch Lomond and Aberfoyle areas are extensively altered to magnesite-quartz and ferroan-dolomite-quartz rocks. Silicification was probably initiated before conversion to carbonate.

Seed Pelleting Technologies: Paving the Way for Resilient and Sustainable Future Farming

open access: yesFood and Energy Security, Volume 15, Issue 1, January/February 2026.
ABSTRACT Seed pelleting is an emerging precision‐agriculture technology that transforms small or irregular seeds into uniform units to enhance mechanical sowing, placement accuracy, and early crop establishment. Pelleting performance depends on the interplay among binder–filler composition, pellet structure, and post‐pelleting moisture conditions ...

Talcoma: A Diagnostic Challenge in Differential Diagnosis of Pleural Masses

open access: yesCase Reports in Radiology, 2015
Talcoma is a pleural mass which may develop as a rare complication following talc pleurodesis. Talc pleurodesis is performed to obliterate the pleural space to prevent recurrent pleural effusions or persistent pneumothoraces.
