Aging is a complex process resulting from internal and external changes, culminating in a
decreased efficacy of cognitive and other biological functions. Studies report that oxidative …

In this paper, we discovered that the 2, 2′-bipyridine (bipy) was able to increase the voltage
and short circuit current of dye-sensitized solar cells (DSSCs) prepared using bixin and …

This work reports the thermo-optical and photophysical properties of annatto extracted from
the seeds of the tropical shrub Bixa Orellana L. Aqueous natural dyes were extracted using …

Aiming to enhance the potential applications of bioproducts, we developed an innovative
approach for their hydrophobization using plasma activation of liquids. In this study …

Surface and interface functionalization are crucial steps to introduce new functionalities in
numerous applications, as faster dynamics occur on surfaces rather than bulk. Within this …

RESUMO A radiação solar, apesar de ser indispensável para a manutenção da vida, está
associada a uma multiplicidade de impactos na saúde humana como o envelhecimento …

Neste estudo, células solares sensibilizadas com corantes (DSSC) naturais bixina e
norbixina foram preparadas usando o semicondutor TiO2 na fase anatasa. As DSSC foram …

Os corantes alimentícios (CAs) possuem a importante função de melhorar a aparência e o
sabor dos alimentos. Existem dois tipos de CAs, os artificiais, que são obtidos por síntese …

A crescente restrição ao uso de certos corantes artificiais perigosos na fabricação de bens
de consumo é um complexo desafio à indústria coureira que busca opções seguras à …
