Die casting thermal diffusion study using the Rao and Schumacher theory [PDF]

FME Transactions
This study investigates the cooling process' efficiency in high-pressure diecasting molds, focusing on key parameters such as the thermal conductivity of the mold material, the cooling channels' diameter, the distance between the channels, and the ...

Engineered Mycelial Scaffolds With Tunable Ultraviolet Protection, Wettability, Thermal Stability, and Spatial Mechanics

Advanced Engineering Materials, EarlyView.
Fungal mycelia grown into biodegradable scaffolds and infused with titania nanoparticles show enhanced ultraviolet shielding, thermal protection, and surface nonwettability. Properties were tuned by drying methods, revealing structure–function relationships.

Characterization upon electrical hysteresis and thermal diffusion of TiAl₃O _x dielectric film

Nanoscale Research Letters, 2011
In this paper, we have investigated the electrical properties of TiAl3O x film as electrical gate insulator deposited by pulsed laser deposition and presented a simple method to describe the thermal diffusion behaviors of metal atoms at TiAl3O x /Si ...

Thermal transport induced by stochastic magnetic fields and turbulence during the thermal quench in tokamak plasmas

Nuclear Fusion
The timescale of thermal quench (TQ) remains a long-lasting issue in tokamak plasmas, which has not been fully understood yet. In this work, based on our previous thermal diffusion model and further considering the scattering caused by the electrostatic ...

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

Advanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Characterization of a Recyclate‐Based MgO‐Steel Composite As‐Sintered Inert Anode Candidate After Exposure to Cryolite Electrolysis

Advanced Engineering Materials, EarlyView.
Carbon‐free inert anodes are essential for decarbonizing aluminum electrolysis. This study investigates a recyclate‐based MgO‐316L steel composite anode tested under galvanostatic Hall–Héroult conditions in cryolite at 1000°C. Microstructural analysis reveals selective MgO fluorination, spinel and oxide layer formation, electrolyte infiltration, and ...

Thermal diffusion measurements [PDF]

Journal of the Franklin Institute, 1925
In a previous paper an account was given of a series of experiments demonstrating the thermal diffusion effect in mixtures of hydrogen and carbon- dioxide. The gas mixtures were passed through a separating device consisting of a glass tube down the middle of which ran a helix of platinum wire heated by a current.
