A Counterintuitive Path to Carbon Storage: Leveraging EOR to Future‐Proof US Oilfields for Geologic Carbon Sequestration

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Geologic carbon sequestration (GCS) is widely seen as essential to achieving net‐zero emissions, yet its large‐scale deployment remains impractical mainly due to economic and political reasons. In this article, we explore the idea that enhanced oil recovery (EOR) may serve as a pragmatic steppingstone for getting GCS‐ready infrastructure in ...

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 34, September 10, 2026.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Methamphetamine Enantiomers: From Chemical Synthesis to Biological Fate

open access: yesChirality, Volume 38, Issue 9, September 2026.
Methamphetamine is an amphetamine‐type stimulant characterized by a single stereogenic center, resulting in two enantiomers, (R)‐(−)‐methamphetamine and (S)‐(+)‐methamphetamine, with distinct biological and pharmacological profiles. These forms exhibit differences in central nervous system activity, metabolism, excretion, and overall physiological ...

Nitrogen‐Starved Wheat: A Multi‐Omics Perspective From Epigenome Regulation to Grain Quality

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
This review establishes epigenetic regulation, specifically H3K27ac and H3K27me3 dynamics at nitrogen transporter, assimilation, and storage protein loci, as a principal determinant of cultivar‐specific nitrogen use efficiency in hexaploid wheat, independent of DNA sequence variation, and identifies the rhizosphere microbiome as an integral but ...

Exergetic efficiency and CO2 intensity of hydrogen supply chain including underground storage

open access: yesEnergy Conversion and Management: X
Hydrogen plays a crucial role in the transition to low-carbon energy systems, especially when integrated into energy storage applications. In this study, the concept of exergy-return on exergy-investment (ERoEI) is applied to investigate the exergetic ...

Maximum water stress is decoupled from climate, traits, and growth in a xeric oak

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2392-2406, September 2026.
We sampled sites across the geographic distribution of blue oak (Quercus douglasii) in California, USA, which spans a large range of mean annual precipitation. Summary Our ability to explain and predict the spatial patterns of forest mortality remains limited.

The Gamma Factory: A New Experimental Paradigm for the Post‐HL‐LHC Era

open access: yesAnnalen der Physik, Volume 538, Issue 8, August 2026.
ABSTRACT The Gamma Factory (GF) proposal is motivated by the recognition of a largely untapped potential of the CERN accelerator complex to enable a new research program at the intersection of particle, nuclear, atomic, fundamental, and applied physics. These fields could benefit from novel experimental tools made possible by a future GF facility.

Effect of Tunnel Ventilation on Hydrogen Dispersion From Leaks in Hydrogen Fuel Cell Trucks

open access: yesEnergy Science &Engineering, Volume 14, Issue 8, Page 3608-3624, August 2026.
This study investigates hydrogen leakage scenarios involving hydrogen fuel cell trucks within tunnels. Using computational fluid dynamics methods, it explores the distribution characteristics of hydrogen concentrations and the efficiency of ventilation under different forced ventilation conditions. ABSTRACT The widespread adoption of hydrogen fuel cell
