Cold Plasma Reticulation of Shape Memory Embolic Tissue Scaffolds.
Polyurethane shape memory polymer (SMP) foams are proposed for use as thrombogenic scaffolds to improve the treatment of vascular defects, such as cerebral aneurysms. However, gas blown SMP foams inherently have membranes between pores, which can limit their performance as embolic tissue scaffolds. Reticulation, or the removal of membranes between adjacent foam pores, is advantageous for improv...
متن کاملInjectable preformed scaffolds with shape-memory properties.
Injectable biomaterials are increasingly being explored to minimize risks and complications associated with surgical implantation. We describe a strategy for delivery via conventional needle-syringe injection of large preformed macroporous scaffolds with well-defined properties. Injectable 3D scaffolds, in the form of elastic sponge-like matrices, were prepared by environmentally friendly cryot...
متن کاملA Monolithic Shape Memory Alloy Microgripper for 3-D Assembly of Tissue Engineering Scaffolds
This paper describes a microgripper used for the micro-assembly of an artificial scaffold for tissue engineering. The porous sponge-like scaffold is a three dimensional construct built by tiny unit parts of biodegradable polymer. This application requires the assembly of several parts by applying a suitable level of force. In this framework, a monolithic shape memory alloy (SMA) microgripper wa...
متن کاملEffects of Cold-Rolling/Aging Treatments on the Shape Memory Properties of Ti49.3Ni50.7 Shape Memory Alloy
In this study, the combined effects of strengthening, precipitates, and textures on the shape recovery ability and superelasticity of thermomechanically treated Ti49.3Ni50.7 shape memory alloy (SMA) in both the rolling and transverse directions were studied by experimental measurements and theoretical calculations. Experimental results and theoretical calculations showed that the 300 °C × 100 h...
متن کاملMicrobial Decontamination of Spices Using Cold Plasma
Most of spices are produced using traditional systems. In unsanitary conditions, spices can contain large numbers of pathogenic microbes such as bacteria, molds and yeasts. Some microorganisms are known as human pathogens, which need disinfection mechanisms that minimize their potential harms to active substances in spices. Use of contaminated spices in foods can significantly decrease the shel...
