Valorization of the peel and husk of guaraná (Paullinia cupana): oil extraction, chemical composition, cytotoxicity, and antitumor potential

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Guaraná (Paullinia cupana) is a fruit native to the Amazon region. Due to its widespread use, primarily in beverages, its production has grown over the years. The seed is the only commercially valuable part of the fruit so the guaraná production chain generates byproducts, including peel, husk, and spent seed.

High Yield Branched Puromycin Linker Design Enables Efficient cDNA Display and Chemical Modification of Peptides

open access: yesBiotechnology and Bioengineering, EarlyView.
A novel puromycin linker for cDNA display was synthesized via SPAAC reaction. Its functionality was confirmed by recovering intact DNA after selection against EpCAM. The system also enabled the verification of bicyclic peptides during display, demonstrating its utility for constructing and screening structurally complex peptide libraries.

Addressing the Attitude Behaviour Perception Gap—Multimethod Sustainable Tourist Behaviour Evaluation

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Quantitative and perceptual studies have been used to define and model sustainable tourist behaviour in past years, but few studies have undertaken qualitative research of actual behaviour to delve deeper into understanding the different classifications of such behaviour. This research employed a three‐phase design, comprising a pretrip survey,

Bifunctional Reduced Graphene Oxide Derivatives for PFOA Adsorption

open access: yesChemistryEurope, EarlyView.
A bifunctional graphene‐based material is developed for selective PFAS adsorption from water. Thermally reduced graphene oxide is modified with quaternary ammonium groups and fluorinated chains, promoting electrostatic and fluorine–fluorine interactions. Surface functionality is characterized by X‐ray photoelectron spectroscopy, atomic force microscopy,
