Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

open access: yesAdvanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Interactions between Molten High‐Silicon Electrical Steels and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

A Compact Spin‐Coated Graphene UWB Antenna for Breast Tumor Detection

open access: yesAdvanced Engineering Materials, EarlyView.
A compact, spin‐coated graphene ultra‐wideband patch antenna designed for breast tumor detection, capable of distinguishing between malignant and benign tumors. This innovative antenna can serve as an effective initial screening tool, particularly in resource‐limited settings such as rural areas, where access to advanced medical equipment like MRI and ...

Nanorobotic Mass Transport

2012 12th IEEE International Conference on Nanotechnology (IEEE-NANO), 2012
Mass transport at attogram (10−18 g) level inside, from, between, and into nanochannels is of growing interest from both fundamental and application perspectives. Nanorobotic manipulation inside a transmission electron microscope (TEM) enables these investigations through its ability to position and assemble pipes, to deliver the mass in a controlled ...

Macro-mass transport

2002
The mechanisms of mass transport include species diffusion and momentum transfer (fluid convection). The effects of these mechanisms on casting solidification will be discussed in this chapter.

Mass transport

1996
This chapter reviews physical processes that contribute to the overall kinetics of any particular reaction. It explains how the reactant molecule must be transported from the bulk solution to the electrode interface in order for electrolysis to proceed, and covers how the reaction products diffuse away from the electrode.

Heat and Mass Transport

1975
As mentioned in Chapter 1 the equations governing heat transfer with small temperature differences also govern transfer of small concentrations of other passive scalar contaminants. Particle-laden flows (Chapter 7) are excluded unless the particles are so small that they move with the flow and are negligibly affected by gravity.
