METHOD OF LOCAL ADRENAL ORGAN-PRESERVING CRYOLYSIS. EXPERIMENTAL STUDY

Бюллетень сибирской медицины, 2013
A method of local adrenal organ-preserving cryolysis using a porous nickelide titanium cryoprobe created for this purpose was developed in experiments in 14 dogs. The efficacy of the method was demonstrated by the morphological evidence and hormone tests.

Shape memory textiles – technological background and possible applications

Communications in Development and Assembling of Textile Products, 2021
While shape memory alloys (SMAs) and shape memory polymers (SMPs) can already be found in diverse applications, shape memory textiles are less often used. Nevertheless, they are regularly investigated. Typical ways to produce shape memory textiles (SMTs)

The effect of solution treatment temperature on SIEM and shape recovery of Fe–Mn–Si shape memory alloy

Journal of Materials Research and Technology, 2021
Solution treatment process is stepwise process in manufacturing of iron based shape memory alloy. It is well known that the grain size of austenite in the solution treatment condition depends on the austenitizing/solutionizing temperature.

Shape Memory Effect in Micro-Sized Shape Memory Polymer Composite Chains

Applied Sciences, 2019
Since the shape memory effect (SME) has been confirmed in micron and submicron sized polyurethane (PU) shape memory polymer (SMP), it might be used in novel micro/nano devices even for surgery/operation inside a single cell.
