steel research international, Volume 97, Issue 4, Page 2241-2249, April 2026.Cold spray deposition of stainless steel (grade: SS304) is evaluated for marine applications, with emphasis on martensitic transformation during impact. Analytical modeling, simulations, and experiments reveal that helium‐assisted spraying of fine powders promotes cooling below the martensitic start temperature, enabling up to ≈40% austenite to ...

Downdraft Devices for Negative Emissions—Quantification Study and Environmental Implication
Greenhouse Gases: Science and Technology, Volume 16, Issue 1, Page 75-89, February 2026.ABSTRACT Methane (CH4) is a potent greenhouse gas with a global warming potential far exceeding that of CO2 over short time horizons. Its removal from the atmosphere remains challenging due to its low ambient concentration and chemical stability. This study explores downdraft energy towers (DETs) as an innovative CH4 mitigation technology that enhances

Flow Structure of a Coaxial Circular Jet with Axisymmetric and Helical Instability Modes
Journal of Fluid Science and Technology, 2011 The flow structures in a coaxial jet with axisymmetric and helical instability modes for a comparatively low Reynolds number were investigated. The flow visualization and the measurements of velocities were carried out in an open water tank. In addition,

Effects of Processing on the Mechanical Performance of GF‐PC Composites: A Multiscale Investigation
Polymer Composites, Volume 47, Issue 2, Page 1300-1315, 20 January 2026.From processing and interface conditions, to macro/micro scale characterization, and postmortem analysis. ABSTRACT A robust fiber‐matrix interface is crucial for any composite system, with higher challenges in thermoplastic matrices compared to thermosets (reaction in composite level).

Design of axisymmetric aerospike nozzle based on modified MOC [PDF]
Scientia Iranica, 2018 In this study a direct method based on the method of characteristics with the assumptions of non-viscous flow and thermal perfect gas is provided to design of axisymmetric plug nozzle. Inputs for numeric code are including output Mach number, specific heat ratio, global gas constant and the number of discrete steps of Prandtl–Meyer expansion fan.

Polymer Engineering &Science, Volume 66, Issue 1, Page 105-121, January 2026.Study on transient parison formation at various strokes during extrusion of Newtonian and viscoelastic fluids. In the presence of an offset between the mandrel and the bushing, Newtonian fluids exhibit a reduction in extrudate diameter, whereas viscoelastic fluids display diameter swelling only at flow rates exceeding a critical threshold.
