flavonoids, are a large class of polyphenols, with more than 4000 combinations. they have an antioxidant role in plant photosynthesis and in the human body they optimally act as an antioxidant, anti-inflammatory, anticancer and protector of the heart. quercetin is in the flavonol group that is used to fight protection specifically against viruses and cancer cells. in this study, comparison of e...

The increasing interest in the extraordinary thermal properties of nanostructures has led to the development of various measurement techniques. Transient thermoreflectance method has emerged as a reliable measurement technique for thermal conductivity of thin films. In this method, the determination of thermal conductivity usually relies much on the accuracy of heat capacity input. For new nano...
