Heat flux balance description of unidirectional freezing and melting dynamics on a translational temperature gradient stage [PDF]
arXiv, 2020 Directional solidification occurs in industrial and natural processes, such as freeze-casting, metal processing, biological cryopreservation and freezing of soils. Translational temperature gradient stage allows to control the process of directional solidification and to visualise it with optical microscope.

Development of Islet Cryopreservation for Type 1 Diabetes Cell Therapy
Zhileng xuebao, 2021 In recent years, cell therapy technology for type 1 diabetes has advanced rapidly, but the lack of donor pancreatic islets and the time and space mismatch between donor and recipient limits its clinical application. Cryopreservation technology provides a

Cryopreservation of single-sperm: where are we today?
Reproductive Biology and Endocrinology, 2020 Background Patients with severe oligospermia and nonobstructive azoospermia have very limited numbers of viable sperm in their epididymal and testicular samples. Thus, cryopreservation of their sperm is performed to avoid repeated sperm retrievals and to

Interfacial Free Energy as the Key to the Pressure-Induced Deceleration of Ice Nucleation [PDF]
The avoidance of water freezing is the holy grail in the cryopreservation of biological samples, food, and organs. Fast cooling rates are used to beat ice nucleation and avoid cell damage. This strategy can be enhanced by applying high pressures to decrease the nucleation rate, but the physics behind this procedure has not been fully understood yet. We

Cryopreservation techniques and their application in vegetatively propagated crop plants in Finland
Agricultural and Food Science, 2008 Cryopreservation protocols have been introduced as techniques for germplasm preservation of vegetatively propagated horticultural and staple food crops. In Finland, cryopreservation has been studied since 1990s, beginning with cryopreservation of forest

Thermographic study of freezing water drops: An insight on Mpemba effect [PDF]
Rev. Mex. Fis. 7, 050601 (2024)Despite decades of research, the Mpemba Effect challenges scientists, prompting further investigation and refinement of existing hypotheses. This work uses optical tools such as thermography to analyze and study the Mpemba effect on drops. We analyze times and contact angle changes with temperature with an easily controlled experiment.
