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.

Prevalence and impact of prescribing cascades in community‐dwelling adults: Longitudinal analysis of the Irish longitudinal study on ageing (TILDA)

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Prescribing cascades occur when medication is prescribed to prevent/treat the adverse effects of another medication and may be intentional/unintentional. This study examines the prevalence of nine prescribing cascades (ThinkCascades) in The Irish Longitudinal StuDy on Ageing (TILDA).

The impacts of biological invasions

open access: yesBiological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

On the Usability of Pt/Al2O3 Catalysts for Exhaust Gas After Treatment in Ammonia Combustion Engines

open access: yesChemie Ingenieur Technik, EarlyView.
Ammonia engines emit no CO2 but exhibit elevated emissions of NH3 and NOx, where conventional SCR systems are not effective due to the significant excess of NH3. This study investigates Pt‐based oxidation catalysts in a bypass configuration to adjust the NH3/NOx ratio, analyzing catalyst parameters and their impact on N2O formation to identify optimal ...

A Methodology to Integrate Closed‐Cycle Heat Pumps into Batch Distillation Columns

open access: yesChemie Ingenieur Technik, EarlyView.
Batch distillation often cannot use vapor recompression due to contamination risks in food and pharma. This study proposes a design for integrating closed‐loop heat pumps using natural fluids. Results show significant energy savings, offering a sustainable alternative to traditional setups.
