Small, EarlyView.Boron seed formation governs BNNT selectivity in an inductively‐coupled plasma system. Local thermodynamics and flow conditions control the abundance and the size of these seeds. BNNT selectivity scales with seed abundance, while the nanotube diameters remain largely unaffected despite seed size changes.

Small Methods, EarlyView.Single‐walled carbon nanotubes (SWNTs) are promising for a wide range of applications. In particular, their exceptional electrical conductivity positions them as potential alternatives to traditional metal conductors. This review identifies the key mechanisms governing their conductivity within composites and proposes practical pathways for translating

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 ...

Characterization of Microwave Plasma Torch for Decontamination [PDF]
Plasma Processes and Polymers, 2008 AbstractAn atmospheric low‐temperature microwave plasma torch has been developed and applied to disinfection. The size of the plasma output is relatively large (35 mm in diameter). Ar gas at a flow rate of 2.2 slm and 85 W microwave power are used. Plasma discharges are produced between the tip of each electrode and the inner surface of the cylinder ...
