“…3b shows that the LED strip remains bright at a temperature of approximate −47.1 °C, indicating that the PVA/QCS-C/MXene hydrogel has good frost-resistance. It is speculated that the crystallization of water in the hydrogel was suppressed due to the introduction of CaCl 2 , 7,46 which resulted in a sharp decrease in the freezing point of the PVA/QCS-C 15 /M hydrogel.…”

“…Much research has been conducted on liquid de-icers [23,24] but less on solids because of factors such as granulometry. Studies on solid RDPs often focus on NaCl and MgCl 2 [25][26][27]. Procedures for testing the melting capacity of ice rely on tools such as isothermal bottles [28] and ice cubes [29]; however, these methods require manipulation during testing, which increases the potential for error.…”

The “bare runway” principle aims to ensure passenger and employee safety by making runways more usable during winter conditions, allowing for easier removal of contaminants like snow and ice. Maintaining runway operations in winter is essential, but it involves considerable cost and environmental impacts. Greater knowledge about the de-icing and anti-icing performance of runway de-icing products (RDPs) optimizes operations. The ice melting test, as per the AS6170 standard, gauges the rate at which an RDP dissolves an ice mass to determine RDP effectiveness. Here, we introduce a novel integrated methodology for assessing RDP-related ice melting. We combine laboratory-based procedures with infrared thermography and Raman spectroscopy to monitor the condition of RDPs placed on ice. The plateau of maximum efficiency, marked by the most significant Raman peak intensity, corresponds to the peak minimum temperature, indicating optimal RDP performance. Beyond this point, RDP efficacy declines, and the system temperature, including melted contaminants and RDP, approaches ambient temperature. Effective RDP performance persists when the ambient temperature exceeds the mixture’s freezing point; otherwise, a freezing risk remains. The initial phases of RDP–ice contact involve exothermic reactions that generate brine, followed by heat exchange with surrounding ice to encourage melting. The final phase is complete ice melt, leaving only brine with reduced heat exchange on the surface. By quantifying these thermal and chemical changes, we gain a deeper understanding of RDP-related ice melting, and a more robust assessment can be provided to airports using RDPs.

“…In the course of freezing and thawing or rewarming, controlling the ice crystals’ formation, growth, and then recrystallization influences all aspects of human activities. − From transportation, cryopreservation, and industrial production to biomedical and other fields, ice is directly or indirectly involved, which is somehow lethal to living things at the macro/micro level . Intensive investigations have been carried out to control and inhibit ice growth and recrystallization including unique approaches by nature, but materials with favorable ice inhibition characteristics are still insufficient.…”

A Synergistic Combination of AuNRs and C Dots as a Multifunctional Material for Ice Recrystallization Inhibition and Rapid Rewarming

Robust platforms and advanced biocompatible materials having diverse performances are in tremendous demand for cryopreservation of biocells, which are greatly limited by the crystallization, formation, and growth of ice crystals. The fickle structure and the arduous extraction process of modern attainable antifreezing proteins cause fatal cryoinjury of the cells making it challenging to develop anti-icing materials. Thus, designing Au colloids is an effective way to combat cell-damaging concerns during the ice freezing–thawing process. Herein, we propose an emerging biomimetic hybrid nanomaterial (AuNR@SiO2-CDs) prepared by combining the photoheating and rewarming controlling characteristics of carbon dots (CDs) and gold nanorods (AuNRs), respectively, via a SiO2 scaffold that has an optimal aspect ratio of ∼4.4. The performance of the material is applied in the freezing and resuscitation of Hela cells. The typical linkage between the AuNR and CDs not only retains the stable structure but also possesses the symmetric functional characteristics of affirmative cryoprotectant materials and sustained low cytotoxicity of cell viability >90%. The cell recovery rate of the Hela cell is significantly improved to ∼60%, which is propped up to >4% higher by the laser irradiation dose. The above hybrid material is paving a path toward novel bionic antifreezing proteins and is envisioned for ice recrystallization inhibition and rapid rewarming.
