Evaluation of rheological and microstructural behavior of modified asphalt binder with chitosan derived from shrimp shell powder

Results in Engineering
Chitosan derived from shrimp shells (SSPCH) was used for the first time as a biological biopolymer to modify the properties of bitumen across high, medium, and low-temperature ranges. Therefore, physical tests (penetration, softening point, and ductility)

Machine Learning Approaches for Predicting Total Organic Carbon From Petrophysical Well Logs in the Wufeng–Longmaxi Shale, Southeast Sichuan Basin, China

Geoscience Data Journal, Volume 13, Issue 4, October 2026.
This study demonstrates the application of machine learning models—Random Forest, XGBoost, and Multiple Linear Regression—to predict Total Organic Carbon (TOC) from well logs, significantly improving TOC prediction accuracy and reliability across diverse geological settings compared to traditional log‐based methods.

Electron‐Beam Irradiation of Ground Tire Rubber in Water for Surface Activation and Improved Recycling in Natural Rubber Compounds

Macromolecular Materials and Engineering, Volume 311, Issue 10, October 2026.
Electron‐beam irradiation of ground tire rubber (GTR) in water activates its surface through water‐radiolysis‐generated oxidants, without altering the rubber's internal structure. Incorporated into natural rubber compounds, the treatment improves the tensile strength by 30% and tear strength by 42% at low doses.

The UK Clean Air Act at 70: An interdisciplinary analysis of historical air quality change

Weather, Volume 81, Issue 10, Page 316-322, October 2026.
2026 marks the 70th anniversary of the first UK Clean Air Act, a pivotal moment for air quality in modern British history. Previous narratives on this legislation have largely centred on pollution in London and monodisciplinary perspectives. This article integrates historical research with reconstructed estimates of PM2.5 concentrations to spotlight ...

Seismic Versus Sub‐Seismic Experimental Mirror‐Like Fault Surfaces in Bituminous Dolostones

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Mirror‐like Surfaces (MSs) are ultra‐polished surfaces frequently found in exhumed seismogenic fault zones in carbonates. They form over a wide range of pressure‐temperature conditions and slip rates, from seismic (≈1 m/s) to sub‐seismic (≈0.1–100 μm/s), reflecting distinct phases of the seismic cycle.

Subsurface Hydrocarbon Biodegradation in the Context of Microbial Habitability and Hydrogeologic, Thermal, and Geologic Evolution of the Colorado Plateau

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Subsurface microbial ecosystems associated with hydrocarbon reservoirs are shaped by temperature, salinity, redox gradients, and fluid flow. However, the drivers of microbial activity and hydrocarbon biodegradation over geologic timescales remain poorly constrained.

Life on the edge: Industrial footprint and edge effects variably influence the distribution of a boreal small mammal

Journal of Applied Ecology, Volume 63, Issue 10, October 2026.
While management in the oil sands typically focuses on the amount of habitat lost and looks to ‘spatial offsets’ of undisturbed habitat elsewhere as a solution, we demonstrate that both composition and spatial configuration must be considered on appropriate spatial scales when developing land‐use strategies in patchy ecosystems undergoing anthropogenic

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

Journal of Petroleum Geology, Volume 49, Issue 4, Page 1179-1194, October 2026.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.
