AÇÕES DE EXTENSÃO EM MICROSCOPIA

Vivências, 2022
Quem nunca se encantou ao ver um microscópio e imaginar o universo por ele desvelado? A criação desse instrumento possibilitou a elaboração de teorias que até hoje são fundamentais para a Biologia. Porém, devido a diversas limitações, a experiência da maioria dos estudantes no Ensino Básico com esse instrumento não é satisfatória.

The lower deciduous dentition of protodidelphids (Mammalia, Marsupialia) from the Itaboraí Basin (lower Eocene), Brazil, and the validity of “Riolestes capricornicus” (Goin et al., 2009)

The Anatomical Record, EarlyView.
Abstract The Itaboraí Basin, Southeastern Brazil, preserved one of the most diverse mammalian faunas from the Paleogene, with Metatheria comprising more than 60% of its diversity. Among identified metatherian clades, it has been argued that Paucituberculata is represented by “Riolestes capricornicus”.

An Analytical Design Model of a Vacuum Pressure Swing Adsorption Process for Biogas Upgrading

Chemie Ingenieur Technik, EarlyView.
A steady‐state model was developed for a vacuum pressure swing adsorption (VPSA) process comprising adsorption, depressurization, and evacuation steps. The resulting analytical plant design model provides the optimal adsorber height required to achieve a target product purity with maximum bed utilization.

Production of recombinant human granulocyte‐macrophage colony‐stimulating factor in thermoinducible E. coli: Tuning inclusion body architecture and protein yield via dissolved oxygen control

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Recombinant protein expression in Escherichia coli frequently results in the formation of inclusion bodies (IBs), which provide high protein accumulation but often require additional steps to recover functional protein. Although culture conditions strongly influence IB physicochemical and structural characteristics, the impact of ...

π‐Extended COUPY Fluorophores for Targeted Near‐Infrared Fluorescence and Lifetime Imaging in Live Cells

Angewandte Chemie, Volume 138, Issue 34, 17 August 2026.
π‐Extended COUPY dyes, obtained by vinylogation of coumarin‐based COUPY scaffolds, shift absorption, and emission deep into the NIR region while preserving compactness and synthetic accessibility. These bright, photostable dyes enable live‐cell imaging, FLIM, and site‐specific peptide conjugation, offering a modular platform for targeted bioimaging and
