The Impulse Atomization process developed at the University of Alberta (Canada) enables metallic powders to be solidified with well controlled process parameters. The inner microstructure of several droplets of Al-4.5wt.%Cu alloy produced by this technique has been investigated by using both...

High strength low carbon microalloyed steels may be adversely affected by the high heat input and thermal cycle that they experience during tandem submerged arc welding (TSAW). The heat affected zone (HAZ), particularly the coarse grained heat affected zone (CGHAZ), i.e., the region adjacent to...

This paper investigates FeCo-based alloy glass formability by high undercooling and high cooling rate solidification technique and the hardness evaluation of the generated samples. For this investigation, Impulse Atomization was used to generate {(Fe60Co40)75B20Si5}96Nb4 powders of different...

Cryopreservation currently is the only method for long-term preservation of cellular viability and function for uses in cellular therapies. Characterizing the cryobiological response of a cell type is essential in the approach to designing and optimizing cryopreservation protocols. For cells used...

The thermal cycles that high strength low alloy (HSLA) low carbon steels experience during welding inevitably affect the microstructure and mechanical properties of the weld joints. It is generally agreed that the coarse-grained heat affected zone (CGHAZ) and the intercritical reheated...

In previous research, we successfully cryopreserved intact human articular cartilage on its bone base with high chondrocyte viability using a vitrification protocol that entailed sequential exposure to several cryopreserving agents (CPAs) at lowering temperatures resulting in a high final...

Amniotic membrane (AM) transplantation is increasingly used in ophthalmological and dermatological surgeries to promote re-epithelialization and wound healing. Biologically active cells in the epithelial and stromal layers deliver growth factors and cytokines with anti-inflammatory,...

Large articular cartilage defects have proven difficult to treat and often result in osteoarthritis of the affected joint. Cryopreservation of articular cartilage can provide an increased supply of tissues for osteochondral allograft but cryoprotective agents are required; however, few studies...

Background Vitrification is a method of cryopreservation by which cells and tissues can be preserved at low temperatures using cryoprotective agents (CPAs) at high concentrations (typically ⩾6.0 M) to limit the harmful effects of ice crystals that can form during cooling processes. However, at...
