Out of all of his innovations, Bell was most proud of the photophone. The rest of the world didn’t feel the same. For one, the device didn’t work when it was cloudy or rainy (obviously, as it needed sunlight). In an article inThe New York Timesfrom August 1880, the photophone wa...
In addition, understanding of the processes by which the micro/nano inclusions improve the properties of the SiAlON matrix is lacking, and more research is needed to fully understand the structure-property relationships of these materials [26, 27]. The objective of this study is to provide a co...
Ever since the discovery and development of polyoxometalates (POMs), it has been known that they can exist in electron-rich reduced forms of different archetypes, structural flexibilities and functionalities. There are now reliable synthetic strategies f

Therefore, during the process, a material expansion typically occurs and significantly higher activation energy than for adsorption is present. This energy is mainly related to covalent bonding of atoms and molecules. Absorbents can be liquids or solids, and the main difference is that their ...

Chronic Kidney Disease (CKD) which involves gradual loss of kidney function is characterized by low levels of a glycoprotein called Erythropoietin (EPO) that leads to red blood cell deficiency and anemia. Recombinant human EPO (rhEPO) injections th
Silicate glasses with metallic nanoparticles (NPs) have been of intense interest in art, science and technology as the plasmonic properties of these NPs equip glass with light modulation capability. The so-called striking technique has enabled precise co
