Designing main-group catalysts for low-temperature methane combustion by ozone

Nature Communications, 2023
The catalytic combustion of methane at a low temperature is becoming increasingly key to controlling unburned CH4 emissions from natural gas vehicles and power plants, although the low activity of benchmark platinum-group-metal catalysts hinders its ...

Navigating the Flames: Comparative Analysis of Cremation Practices in the Roman and Early Medieval Periods at Gbely‐Kojatín (SK) and Přítluky (CZ)

Archaeometry, EarlyView.
ABSTRACT Cremation became the dominant funerary practice in the Middle Danube Region during the Roman Period (RP) (1st–4th century) and reappeared in the Early Medieval Ages (EMA) (6th/7th–8th century). This study aims to reconstruct differences in cremation conditions from the Gbely‐Kojatín site (Slovakia, RP and EMA) and the Přítluky site (Czech ...

Persistence and potential of soil organic carbon in nature‐based climate solutions: A review of managed disturbances

PLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 811-830, May 2026.
Implementing nature‐based climate solutions is important for mitigating climate change, which is a global issue, but requires local adjustments in management practices. Using the association between soil carbon and minerals as a proxy for carbon persistence, we evaluated the effect of different management regimes on soil carbon sequestration and loss ...

Imaging gas in a combustion engine with high‐energy X‐ray Compton scattering

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 788-793, May 2026.
Compton‐scattering imaging has been applied to a combustion engine under operation for the first time. With a time‐resolved technique, a crank‐angle dependency of Compton‐scattered X‐ray intensity is obtained at different positions in a combustion chamber.We have developed a time‐resolved Compton‐scattering imaging technique for visualizing gas ...

Effects of warming on plant uptake of post‐fire nitrogen in an arctic heath tundra

New Phytologist, Volume 250, Issue 3, Page 1510-1521, May 2026.
Summary Postfire nitrogen (N) becomes increasingly important with the rising frequency of fires in arctic tundra, and climate warming is expected to accelerate plant recovery following fire. However, how plants differ in utilizing this postfire N and how their postfire N uptake responds to warming remains unknown.

Recycled Cellulose‐Based Colorimetric Indicators for Non‐Contact Detection of Food Contamination

Advanced Sustainable Systems, Volume 10, Issue 4, April 2026.
Recycled cellulose acetate films, functionalized with red cabbage anthocyanins, combine antioxidant activity and pH‐responsive color changes for smart food packaging. They extend shelf life by preventing oxidation and enable non‐contact detection of bacterial contamination via VOC‐triggered color shifts.

A predictive model of natural gas mixture combustion in internal combustion engines

Ingeniería e Investigación, 2007
This study shows the development of a predictive natural gas mixture combustion model for conventional com-bustion (ignition) engines. The model was based on resolving two areas; one having unburned combustion mixture and another having combustion ...

Unburned Carbon in Coal Fly Ash: Exploring Its Potential for Electrochemical Energy Storage in Supercapacitors

Advanced Energy and Sustainability Research, Volume 7, Issue 4, April 2026.
The graphical abstract illustrates a circular waste to value pathway in which coal fly ash is upgraded by isolating unburned carbon and converting it into functional carbon materials. Through carbonization and activation, UC‐derived carbon is transformed into high surface area electrodes for supercapacitors, supporting sustainable energy storage and ...
