Cloning of novel low and high molecular weight heat shock genes in wheat
… a vital role in the plant's ability to survive high temperature stress. Cloning low and high molecular weight HSPs from a thermotolerant variety of wheat will provide a building block for later studies of their function. Moreover, once significance of a HSP gene in plant thermotolerance is …

Chain-end functionalization and modification of polymers using modular chemical reactions
Taking advantage of ATRP and using functionalized initiators, different functionalities were introduced in both α and ω chain-ends of synthetic polymers. These functionalized polymers could then go through modular synthetic pathways such as click cycloaddition (copper-catalyzed or copper-free) or …
