Azobenzene's Cross‐Scale Optics and Photonics: Molecular Photoswitching, Mesoscopic Material Motions, and Adaptive Devices

open access: yesAdvanced Materials, EarlyView.
Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...

Frost Resistance of Polymers

Russian Chemical Reviews, 1970
Papers by Soviet and foreign authors on the problem of frost resistance are surveyed, and definitions are suggested for the concepts of the technical and the theoretical frost resistance of polymers. Existing qualitative methods for determining the frost resistance of various types of polymeric materials are discussed, together with quantitative ...

Frost resistant concrete

Construction and Building Materials, 1996
Abstract There are two basic frost durability problems: internal cracking due to freezing and thawing cycles, and surface scaling, generally due to freezing in the presence of deicer salts. Although there are still parts of the problem which are not perfectly well understood and warrant further investigation, particularly with respect to the ...

Frost Resistance in Plants

1987
Frost resistance is a genetically determined physiological trait which is expressed under environmental constraints. The ability to harden is the basis for the differences between individuals, ecotypes, varieties and species with respect to potential frost resistance.

Genes for frost resistance in wheat

Euphytica, 2001
Wheat varieties differ in their responses to low temperatures. Genetic studies on frost resistance in wheat are difficult because the effects are quantitative in nature and thus require precise genetic material and reproducible experimental conditions.

The barley Frost resistance-H2 locus

Functional & Integrative Genomics, 2014
Frost resistance-H2 (Fr-H2) is a major QTL affecting freezing tolerance in barley, yet its molecular basis is still not clearly understood. To gain a better insight into the structural characterization of the locus, a high-resolution linkage map developed from the Nure × Tremois cross was initially implemented to map 13 loci which divided the 0.602 cM ...

Mechanisms of frost resistance in Arabidopsis thaliana

Planta, 2018
Freezing resistance strategies vary in Arabidopsis depending on origin. Southern accessions may avoid or tolerate freezing, while northern ones are always tolerant and reduce the proportion of freezable tissue water during acclimation. Survival of sub-zero temperatures can be achieved by either avoiding or tolerating extracellular ice formation ...

Frost Resistance in Insects

1970
Publisher Summary Insects hibernating in temperate and cold regions are, as a rule, able to withstand climatic low temperatures, although they may suffer serious injury if the cold weather is too severe or too prolonged. They can avoid such cold injury by two common means: supercooling and frost resistance.

The Frost Resistance of LYTAG Concrete

Advanced Materials Research, 2014
This article studies the frost resistance of LYTAG concrete and ordinary concrete respectively used the RILEM recommended test method (CIF) about frost resistance of concrete. The results indicate that the single surface's frost resistance of Lytag concrete with mineral admixture is much better than normal density concrete's. And the rank of the single
