Computational Analysis of Spray Angle Effects on Combustion and Emissions in Methane‐Diesel Dual‐Fuel Engine

Energy Science &Engineering, Volume 14, Issue 3, Page 1100-1112, March 2026.
This study concluded that wider spray angles produce wall impingement and greater unburned hydrocarbons in methane‐diesel dual‐fuel engines, whereas 110° balances efficiency and emissions. ABSTRACT A diesel methane dual fuel engine appears as a potential means for lowering emissions while retaining useful thermal efficiency.

Optical diagnostics-based numerical modeling of a compression-ignition optical research engine implementing ducted fuel injection

Applications in Energy and Combustion Science
Ducted fuel injection (DFI) is a promising strategy to dramatically reduce engine-out soot emissions from compression-ignition (CI) engines. To accelerate the integration of DFI into real-world engines, computational fluid dynamics (CFD) is a powerful ...

Scutellaria Baicalensis‐Derived Carbon Dots Alleviate Colitis by Activating Anti‐Inflammatory and Barrier‐Protective Cascades

Small Structures, Volume 7, Issue 3, March 2026.
Using traditional Chinese medicine Scutellaria baicalensis as a precursor, CDs were synthesized through carbonization, microwave, and hydrothermal methods. Among these, Hydro‐CDs exhibited optimal biocompatibility and potent anti‐inflammatory and antioxidant activities.

PREAMBULAR HISTORY: THE VIEW OF THE PAST IN KEY HUMAN RIGHTS INSTRUMENTS

History and Theory, Volume 65, Issue 1, Page 3-31, March 2026.
ABSTRACT This article claims that the preambles of foundational human rights instruments, taken together, articulate a consistent view of the past. This view is firmly rooted in historical processes, embedded in metaphysical truths, and enacted in service of the future. Part 1 assesses the strengths and weaknesses of the “preambular approach to history”

Pathogenic fungus Ustilago maydis exploits the lateral root regulators to induce pluripotency in maize shoots

New Phytologist, Volume 249, Issue 6, Page 2974-2985, March 2026.
Summary Biotrophic plant–pathogens secrete effector molecules to redirect and exploit endogenous signaling and developmental pathways in their favor. The biotrophic fungus Ustilago maydis causes galls on all aerial parts of maize. However, the responsible gall‐inducing effectors and corresponding plant signaling pathway(s) remain largely unknown.

Deep Convection‐Driven Downward Transport of Trace Gases and Aerosols From the Free Troposphere to the Boundary Layer

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Deep convective clouds regulate Earth's energy and moisture budgets, yet their impact on the atmospheric boundary layer (BL) composition remains underexplored. Using long‐term observations from three mid‐latitude sites, we show that deep convection (DC) consistently enhances nighttime surface ozone and is often accompanied by modest increases ...

Semi‐Volatile Organic Partitioning Improves Simulation of Biomass Burning Aerosol Mixing State Evolution

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Biomass burning aerosols significantly contribute to atmospheric composition and radiative forcing, with black carbon (BC) mixing states critically influencing optical properties and climate impacts. Recent field observations reveal a systematic three‐phase evolution in BC coating thickness during plume aging: rapid initial growth, quasi ...

Non‐Volatile Particulate Matter as Cores Driving Aerosol Mixing States and Light Absorption

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The mixing state of light‐absorbing particles critically influences aerosol optical properties, thereby affecting global radiative forcing. This study focuses on non‐volatile particulate matter (NV‐PM)—the fraction remaining after thermal denudation at 300°C—has received limited attention.
