Luminescent Pb-free perovskites: low-cytotoxicity materials for primary thermal...
Passini, Luan N.; Maturi, Fernando E.; Pugina, Roberta S.; Hilário, Eloísa G.; Fontes, Marina; Barud, Hernane S.; Carlos, Luís D.Selecting a suitable host matrix to perform temperature sensing in biomedical applications requires low cytotoxicity, facile synthesis, and an ability to be doped with light-emitting ions. With this perspective, indium-based halide double perovskites, specifically Cs2AgIn0.9Bi0.1Cl6, Cs2Ag0.6Na0.4InCl6, and Cs2Ag0.6Na0.4In0.9Bi0.1Cl6, were chosen as host materials to develop lanthanide-based primary thermometer...
Cashew Gum (Anacardium occidentale) as a Potential Source for the Production of...
Loureiro, Kahynna C.; Jäger, Alessandro; Pavlova, Ewa; Lima-Verde, Isabel B.; Štěpánek, Petr; Sangenito, Leandro S.; Santos, André L. S.Every year, more than thirty thousand tons of Cashew gum (Anacardium occidentale, family: Anacardiaceae) are produced in Brazil; however, only a small amount is used for different applications in foodstuff and in pharmaceutical industries. As a raw material for the production of drug delivery systems, cashew gum is still regarded as an innovative compound worth to be exploited. In this work, cashew gum was extr...

No. of bitstreams: 0 Previous issue date: 2020-10-14; Cellulose is everywhere and renovates in nature continuously and rapidly, while petroleum does not. Unlike the latter, cellulose biodegrades and may represent a carbon sink. Inspired by the multiscale architecture of cellulose, we report on all-cellulose composites comprising cellulose ether as a matrix...
