Advanced Functional Materials, EarlyView.Cyclic unloading‐aging‐reloading micro‐tensile tests under various aging durations and temperatures, combined with comprehensive microstructural characterization reveal that the yield point phenomenon in Aluminum‐Carbon (Al‐C) thin films originates from Cottrell atmosphere formation.

Advanced Functional Materials, EarlyView.Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...

Advanced Functional Materials, EarlyView.This work develops polyacrylamide‐alginate (PAM‐Alg) double‐network hydrogel fibers for multimodal perception and intelligent human‐machine interfaces. The covalent‐ionic network provides high strength, toughness, and stable conductivity. Easily woven into wearables and integrated with soft robots, the fibers enable object and temperature recognitions ...

Cooling Rates During Flash Cooling
Journal of Applied Crystallography, 1998Flash cooling of macromolecular crystals was investigated by measurement of the cooling rates achieved by different cryoprotectant solutions (glycerol, sucrose and polyethylene glycol) with different sample volumes (0.2–0.8 mm3) and by different cooling agents (cold nitrogen or helium gas, liquid nitrogen and liquid propane).

Plunge‐cooling of tissue blocks: determinants of cooling rates
Journal of Microscopy, 1985SUMMARYTissue blocks have been plunged into a liquid coolant and the resultant ice‐crystal damage is discussed. Some blocks have been frozen without apparent ice‐crystal damage; they were not treated with cryo‐protectants but were mounted on streamlined foil supports which separated the specimen from the thermal mass of the support pin.

Rapid cooling is essential to prevent multiplication of microorganisms in potentially hazardous foods. This requirement is frequently not met with viscous foods in large containers. The time required to cool an 8-gal container of white sauce from 105 to 57 F was 25 hr.

Cool! Rates of Heating and Cooling
Journal of Chemical Education, 2007In this Activity, students measure and graph the rate of warming for a chilled thermometer bulb held in room temperature air, for a chilled bulb held between two fingers, and for a few milliliters of chilled water. Students are familiar with the everyday phenomena of warming, but measurement affords the unexpected result that the process is not linear.

On crystal size and cooling rate
Journal of Microscopy, 1986SUMMARYA theoretical model is proposed which is used to derive a quantitative relationship between the critical cooling rate and average crystal size at any location within a biological specimen of given shape subject to rapid freezing. The model is applicable to the slamming, plunging or spraying methods of cryofixation provided the ice crystal size ...

Cooling rates in splat cooling
Materials Science and Engineering, 1967Abstract Calculations and experimental observations made on cooling rates during splat quenching are presented. Three possible types of cooling behavior are discussed: ideal cooling, intermediate cooling and Newtonian cooling. The effects of splatting-process variables on the cooling rates are described, the most important of these variables being ...
