Ionic liquid (IL)-functionalized graphene oxide (GO) containing gold nanoparticles (Au NPs) (5.4-5.9 nm) deposited by sputtering combined with cholesterol oxidase appears to be a suitable and efficient biosensor for total detection. These biosensors showed good linear range (25-340 μmol L-1) determination colorimetric tests. In addition, control experiments in the presence of interferents demonstrated that hybrid materials provided selective detection cholesterol. The biosensing activities...
In this work, imidazole- or imidazolium-based benzothiadiazole ligands functionalized on graphene oxide combined with cholesterol oxidase constitute efficient, robust, and easy-to-handle materials high biosensing activity for the detection of by colorimetric methods. The presence lanthanum(III) supported as a possible coordinating site was also evaluated, its bioactivity compared to that analogous material without rare-earth metal. Our results demonstrated...
Abstract Tantalum oxide nanoparticles prepared from the hydrolysis of 1‐alkyl‐3‐methylimidazolium hexachlorotantalate ionic liquids showed an unprecedented efficiency for photocatalytic degradation methylene blue and methyl orange dyes in aqueous solutions. Indeed, photodegradation these (up to 94 %) promoted by Ta 2 O 5 occurred shorter reaction times when compared commercially available under same conditions. Moreover, presence residual liquid pH medium seem play significant roles process....
Resumo A ideia de que existia um arranjo espacial dos átomos na molécula foi objeto controvérsia entre os químicos no início do século XIX, pois a prevalecente era moléculas não tinham dimensões. Assim, história como as bases da estereoquímica foram construídas nos revela uma verdadeira batalha científica o ceticismo alguns influentes e ideias jovens cientistas. As desavenças impediram esforço pesquisadores passaram ser apoiados por experientes estavam igualmente convencidos havia relação...
