Confirming the impact origin of the São Miguel do Tapuio structure, northeastern Brazil

Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1263-1287, July 2026.
Abstract The São Miguel do Tapuio structure (SMT) is a remarkable, nearcircular feature of about 21 km diameter, centered at 5°37.6′ S, 41°23.3′ W in Piauí state, northeastern Brazil. The structure is located within the sedimentary strata of the Paleozoic–Mesozoic Parnaíba Basin and predominantly comprises sandstones of the Devonian Pimenteiras and ...

Simultaneous Generation of Topographic Models and Manning Roughness Coefficient Maps From Tri‐Stereoscopic Satellite Images: Application to the Huarmey River, Peru

The Photogrammetric Record, Volume 41, Issue 195, July‐September 2026.
Tri‐stereoscopic PeruSat‐1 imagery enables the simultaneous generation of 0.70 m‐resolution topography and spatially distributed Manning roughness maps, achieving 0.434 m vertical accuracy. Integrated into HEC‐RAS, these products provide consistent, high‐resolution inputs that improve hydraulic modelling and flood risk assessment in data‐scarce river ...

Stimuli‐Responsive Hydrogels for Optical Applications: Mechanisms, Architectures, and Translational Challenges

Aggregate, Volume 7, Issue 6, June 2026.
The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.

Detection of Particulate Matter With Lock‐In Thermography

CleanMat, Volume 3, Issue 2, Page 67-73, June 2026.
Accurate quantification of black carbon is essential due to its significant impact on climate, air quality, and human health. Lock‐in thermography (LIT), as implemented by NanoLockin's instrument Calorsito, offers a sensitive, scalable, and reproducible approach for detecting black carbon on filter substrates.

Possible gaso-petroleum occurrence from non-seismic and non-conventional exploration methods in the Central Basin, Cuba

Boletín de Ciencias de la Tierra, 2020
In various geological situations, seismic data provides little information about whether a trap contains hydrocarbons. It is well documented that the generality of hydrocarbon accumulations has predominantly vertical microfiltration.

Occupational Exposure to Factory‐Derived Particulate Matter 2.5 Induces Cutaneous Toxicity in Workers and HaCaT Keratinocytes Through Oxidative Stress and Inflammation

Journal of Applied Toxicology, Volume 46, Issue 6, Page 2145-2157, June 2026.
ABSTRACT This study aimed to evaluate the toxicological effects of occupational exposure to factory‐derived particulate matter (PM2.5) on human skin, emphasizing its role as a potential target organ of environmental toxicants. An epidemiological survey comparing factory and nonfactory workers was conducted by assessing their skin elasticity and color ...
