Lifting Phenomena due to Vortex-Flame Interactions of Jet Diffusion Flames.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 2000
Lifting phenomena caused by vortex-flame interactions have been investigated about diluted-propane jet diffusion flames forced by a speaker installed at the bottom of a fuel tube. Open jet diffusion flames were formed on a co-flow burner composed of the inner fuel tube and an outer air tube. Two type nozzles of rim thickness of 1 mm and 0.2 mm were set

Noise, Vibration, and Harshness (NVH) Challenges in Hydrogen Internal Combustion Engine Vehicles

Energy Science &Engineering, Volume 14, Issue 2, Page 1067-1080, February 2026.
ABSTRACT This paper presents a state‐of‐the‐art literature review on noise, vibration, and harshness (NVH) in hydrogen‐fuelled internal combustion engines. Studies published between 2011 and 2025 were screened, covering fundamental flame physics, test‐bench work, and recent prototype vehicles.

Engineering Hierarchically Nano‐Structured Cu Foams: Dynamic Hydrogen Bubble Templated Binder‐Free Freestanding Electrodes for Energy Applications

Small, Volume 22, Issue 8, 6 February 2026.
The competition between H2 evolution (HER) and Cu electrodeposition during the dynamic hydrogen bubble templating (DHBT) crucially influences the synthesized foam morphology. Generally, when HER is dominating, numerous small H2 bubbles form, resulting in compact Cu foams.

Needling Therapy for Burn Injury and Related Complications: A Scoping Review of Experimental and Clinical Studies

International Wound Journal, Volume 23, Issue 2, February 2026.
ABSTRACT Needling therapy may be a novel alternative therapeutic intervention for burn injuries and related complications. This scoping review aimed to comprehensively evaluate the evidence status of needling therapy for burns and their complications. Studies on needling therapy for burns and related complications were retrieved from inception to 1st ...

Hydrogen in the Natural Gas Network—Relevance for Existing Fire Precautions

Fire
Power-to-gas technology can be used to convert excess power from renewable energies to hydrogen by means of water electrolysis. This hydrogen can serve as “chemical energy storage” and be converted back to electricity or fed into the natural gas grid. In

Integration of light quality signals regulates ABA abundance and stomatal movements during seedling establishment

New Phytologist, Volume 249, Issue 3, Page 1253-1267, February 2026.
Summary Obtaining sufficient light for photosynthesis and avoiding desiccation are two key challenges faced by seedlings during early establishment. Perception of light quality via specialised photoreceptors signals the availability of sunlight for photosynthesis.

Facies analysis provides new insights into event bed deposition in a hadal trench environment

Sedimentology, Volume 73, Issue 2, Page 441-477, February 2026.
ABSTRACT Hadal trenches preserve exceptional sedimentary archives of past geological events, yet their depositional processes remain poorly constrained. The Japan Trench captures complex earthquake‐triggered event beds that record repeated sediment‐gravity flows that deliver terrigenous and biogenic material into the trench, informing palaeoseismic ...
