Application of X-ray Microtomography to Quantify the Liquid Fraction of M2 Steel for Semi-solid Forming process [PDF]

open access: yes, 2013
Thixoforging, one variant of semi-solid metal processing in which the metallic alloys are processed at low liquid fraction (0.1< Fl < 0.3), is used to produce complex parts with high mechanical properties.

Solid-liquid equilibria for the dimethyl ether plus carbon dioxide binary system [PDF]

open access: yes, 2010
A recently built experimental setup was employed for the estimation of the solid-liquid equilibria of alternative refrigerants systems. The behavior of dimethyl ether (DME) + carbon dioxide was measured down to temperatures of 131.6 K.

Regulated Dynamics with Two Monolayer Steps in Vapor–Solid–Solid Growth of Nanowires

open access: yes, 2022
The growth of ZnTe nanowires and ZnTe–CdTe nanowire heterostructures is studied by in situ transmission electron microscopy. We describe the shape and the change of shape of the solid gold nanoparticle during vapor–solid–solid growth. We show the balance

Deterministic nucleation of InP on metal foils with the thin-film vapor–liquid–solid growth mode [PDF]

open access: yes, 2014
A method for growth of ultralarge grain (>100 μm) semiconductor thin-films on nonepitaxial substrates was developed via the thin-film vapor–liquid–solid growth mode.

Silicon Microwire Photovoltaics [PDF]

open access: yes, 2010
The favorable bandgap and natural abundance of Si, combined with the large expertise base for semiconductor wafer processing, have led to the use of wafer-based crystalline Si in the vast majority of photovoltaic cells and modules produced worldwide ...

Boundary layer chemical vapor synthesis of self-organized radial filled-carbon-nanotube structures [PDF]

open access: yes, 2013
We report a new chemical vapor synthesis method that exploits random fluctuations in the viscous boundary layer between a laminar vapor flow and a surface to yield a not previously observed product: radial ferromagnetically filled-carbon-nanotube ...

Growth of Self-Catalyzed InAs/InSb Axial Heterostructured Nanowires: Experiment and Theory

open access: yesNanomaterials, 2020
The growth mechanisms of self-catalyzed InAs/InSb axial nanowire heterostructures are thoroughly investigated as a function of the In and Sb line pressures and growth time. Some interesting phenomena are observed and analyzed. In particular, the presence

Effect of partial wetting on liquid/solid mass transfer in trickle bed reactors [PDF]

open access: yes, 2007
The wetting efficiency of liquid trickle flow over a fixed bed reactor has been measured for a wide range of parameters including operating conditions, bed structure and physico-chemistry of liquid/solid phases.

Shape modification of Si nanowires by using faceted silicide catalysts nucleated in Au-Si catalyst solution during the growth

open access: yesAIP Advances, 2013
The shape modification of Si nanowires is demonstrated using faceted solid silicide catalysts. The Si nanowires were grown on Si(111) substrates covered with Au as a catalyst using MnCl2 and Si powders as source materials.

Fast vapor phase growth of SiO2 nanowires via surface-flow on Ag core/SiO2 shell structure

open access: yesAIP Advances, 2012
Uniform, millimeter-long SiO2 nanowires were grown from co-evaporation of Ag2O and SiO powders. The ‘frozen’ growth scenario by cooling enables revelation of the vapor-liquid-solid mechanism here in action, which is generally inaccessible due to the high
