Obtenção e caracterização de blendas colágeno-quitosana [PDF]
Química Nova, 2002 Biodegradable polymer blends were obtained using collagen and chitosan. Membranes of collagen and chitosan in different proportions (3:1, 1:1 and 1:3) were prepared by mixing their acetate solutions (pH 3.5) at room temperature. The blends were characterized by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier Transform

A review on egg pasteurization and disinfection: Traditional and novel processing technologies
Comprehensive Reviews in Food Science and Food Safety, Volume 22, Issue 2, Page 756-784, March 2023., 2023 Abstract Salmonella Enteritidis is a pathogen related to many foodborne outbreaks involving eggs and egg products. Regulations about whether eggs should be pasteurized are very different and inconsistent worldwide. In the United States, eggs are not required to be pasteurized. Hence, less than 3% of the eggs in the country are pasteurized. The standard

Energy Technology, Volume 10, Issue 8, August 2022., 2022 Recently, non‐fullerene acceptors (NFAs) have revolutionized organic photovoltaics (OPVs) research. Three star‐shaped NFAs are herein reported and tested in flexible OPVs upon blending with the standard P3HT donor. The molecules have different terminal units (indene malononitrile and barbiturate) and one or two thiophene spacers. The most promising NFA

Cibalackrot Dendrimers for Hyperfluorescent Organic Light‐Emitting Diodes
Macromolecular Rapid Communications, Volume 43, Issue 16, August 2022., 2022 1st‐Generation Cibalackrot dendrimers with new highly‐twisted mesityl dendrons are synthesized, enabling high solubility and low aggregates in blend films. Hyperfluorescent dendrimer organic light‐emitting diodes (OLEDs) are first demonstrated to process external quantum efficiencies (EQEs) of >10% (@ 100 cd m−2), high current densities (>200 mA cm−2),
