Modeling nitrogen species from ammonia reciprocating engine combustion in temperature-equivalence ratio space

Applications in Energy and Combustion Science
This paper explores nitrogen species formation in temperature (T)-equivalence ratio (ϕ) space under internal combustion engine-relevant conditions using zero-dimensional modeling. The analysis reveals that N2O and NO are formed in a much larger region of

Detecting and attributing climate change effects on vegetation: Australia as a test case

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change is contributing to vegetation changes that threaten life support systems. Yet, inherent climatic variability and past and present human actions—such as clearing, burning and grazing regimes—also alter vegetation and complicate understanding of vegetation change. Australian ecosystems exemplify such complexity.

Effects of natural gas admission location and timing on performance and emissions characteristics of LPDF two-stroke engine at low load

Case Studies in Thermal Engineering
Low-pressure gas-admission marine two-stroke engines have significant potential for reducing emissions in the shipping industry. However, they exhibit poor combustion quality under low-load conditions, leading to lower thermal efficiency and high levels ...

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 ...

Biocarbon Suitability Evaluation for Direct Injection in Blast Furnace Ironmaking

steel research international, EarlyView.
This study examines densified biocarbon for direct injection in blast furnace ironmaking to reduce greenhouse gas (GHG). Enhanced burnout performance, along with favorable reactivity and carbon structure of the combustion residue, supports its suitability for blast furnace injection. Modeling results indicate that up to a 27% reduction in GHG emissions

Flame Retardant Polyolefins Using Fibers From Leather Waste: Adjusting Extrusion Variables to Balance the Property Profile

Journal of Vinyl and Additive Technology, EarlyView.
Adjusting extrusion variables are a key to balance the flame retardancy and mechanical properties of polyolefin/leather waste fiber composites. ABSTRACT The extrusion processing variables represent a key to the optimal use of additives and thus the development of flame‐retardant polymer composites. Adjusting the property profile, for example, finding a

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 ...

Fire intensity effects on flowering and post‐fire bud activity in the endemic savanna bunchgrass Aristida beyrichiana

Plant Biology, Volume 28, Issue 2, Page 452-460, March 2026.
Although flowering and bud activity are not significantly affected by fire intensity, wiregrass' bud bank changes with time since fire. Abstract The bud bank of perennial grasses is a key aspect of their reproduction and longevity in frequently burned ecosystems.

On the Usability of Pt/Al2O3 Catalysts for Exhaust Gas After Treatment in Ammonia Combustion Engines

Chemie Ingenieur Technik, Volume 98, Issue 1-2, Page 27-36, February 2026.
Ammonia engines emit no CO2 but exhibit elevated emissions of NH3 and NOx, where conventional SCR systems are not effective due to the significant excess of NH3. This study investigates Pt‐based oxidation catalysts in a bypass configuration to adjust the NH3/NOx ratio, analyzing catalyst parameters and their impact on N2O formation to identify optimal ...
