Opportunities for the U.S. Geological Survey's National Seismic Hazard Model to Improve Seismic Risk Assessment of Critical Infrastructure

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
As fragility and risk modeling techniques and computational capabilities evolve, complemented by moving toward more routine and systematic seismic risk assessment of all buildings and critical infrastructure, the authors pose a few critical questions to investigate how the U.S. Geological Survey (USGS) National Seismic Hazard Models (NSHMs) can be used

Thermodynamic Insights Into Direct Methane to Methanol Conversion Using O2 and CO2 Oxidants

open access: yesChemistryOpen, Volume 15, Issue 5, May 2026.
A thermodynamic analysis compares O2 and CO2 for the direct partial oxidation of methane to methanol. While O2 offers higher theoretical conversions, it poses safety risks and favors total oxidation. CO2 presents a safer, more sustainable alternative despite its thermodynamic limitations.

Energy and Environmental Performance of Biodiesel Derived From Waste Vegetable and Animal Oils: Integrated Energy Balance, Process Optimization, and Feasibility Assessment

open access: yesGCB Bioenergy, Volume 18, Issue 5, May 2026.
This study demonstrates a highly efficient biodiesel production route from waste vegetable and animal oils, achieving a net energy ratio (NER) of 7.8–8.2 and over 85% greenhouse‐gas reduction. Methanol recovery and optimized logistics enhanced energy efficiency, validating waste‐oil biodiesel as a sustainable circular‐bioeconomy fuel.

Emerging Technologies for Biobutanol Production via Syngas Fermentation

open access: yesGCB Bioenergy, Volume 18, Issue 5, May 2026.
Biobutanol production from syngas is promising but limited by microbial energy conservation and gas–liquid mass transfer. This review integrates advances in cultivation control and bioreactor engineering with next‐generation biological tools including metabolic rewiring, co‐cultivation and chain elongation, and electro‐fermentation to enable carbon ...
