Plasmonic Bubbles in n-Alkanes [PDF]

, 2018
In this paper we study the formation of microbubbles upon the irradiation of an array of plasmonic Au nanoparticles with a laser in n-alkanes ($C_{n}H_{2n+2}$, with n = 5-10). Two different phases in the evolution of the bubbles can be distinguished.

Evaluating Plasma Torches as a Low‐Decarburization Preheating Method for MgO–C Refractory Linings

steel research international, EarlyView.
This study evaluates direct current (DC) plasma torches using nitrogen as an alternative preheating method for magnesia‐carbon (MgO–C) refractory‐lined ladles. Full‐scale trials at 0.7 and 1.5 MW are compared to conventional gas burner. Plasma‐heated samples show lower decarburization and improved surface integrity due to partial sintering and reduced ...

Geometry optimization of the solar micro-channel PV/T evaporator based on regional differentiation in China

Results in Engineering
Introducing micro-channel (MC) to photovoltaic/thermal (PV/T) evaporator can significantly improve the utilization efficiency of solar energy. However, the regional performance difference of a MC-PV/T evaporator and the superheat degree demand of a ...

Microstructure Evolution in Directionally Solidified Fe–C–Mn–(Si) Peritectic Steels

steel research international, EarlyView.
This study investigates how growth velocity and silicon additions affect dendritic morphology, primary arm spacing, and mushy‐zone evolution in directionally solidified quaternary peritectic steels. Silicon substantially broadens the freezing range and lengthens the mushy zone, increasing susceptibility to interdendritic cracking.

Shape‐Determined Kinetic Pathways in 2D Solid–Solid Phase Transitions

Advanced Science, Volume 13, Issue 4, 19 January 2026.
By simulating 2D ball‐stick pentagon, hexagon, and octagon systems, the kinetics of solid–solid phase transition is investigated, which is characterized by the loss of body‐orientation order. During which, the local defects of body‐orientation self‐organize into three different patterns, originated from the shape‐determined kinetic pathways, which may ...
