Metal‐Free and Solvent‐Free CO2 Fixation Into Cyclic Carbonates Catalyzed by a Deferiprone‐Derived Bifunctional System

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A simple bifunctional organocatalyst derived from the FDA‐approved chelator deferiprone efficiently promotes CO2 fixation into cyclic carbonates. By combining epoxide activation and nucleophilic ring opening in a single scaffold, quantitative conversions are achieved under mild, metal‐free conditions. High activity, broad substrate scope, and excellent

Validation and Application of an HPLC–UV Method for the Quantification of 3‐O‐Methylquercetin in Nasal Mucosa

open access: yesELECTROPHORESIS, EarlyView.
This study improved an HPLC–UV method for quantifying 3‐O‐methylquercetin in porcine nasal mucosa following ICH M10 and ANVISA (Brazil) guidelines, assessing selectivity, linearity, accuracy, precision, and robustness. The method was applied for the first time to evaluate release, permeation, and retention profiles of a nasal formulation.

Validated RP‐HPLC–UV Method for the Quantitative Analysis and Stability Evaluation of Amoxicillin in Paediatric Gummy Tablets

open access: yesELECTROPHORESIS, EarlyView.
A validated RP‐HPLC–UV method was successfully applied for amoxicillin determination in gummy tablets. The method is useful for an accurate amoxicillin content determination in paediatric gummies and was applied to study the stability profile of the drug, evaluated over 6 months under storage conditions.

A study of chevron type plate design on pressure drop and friction factor of brazed plate heat exchanger

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Brazed plate heat exchanger (BPHE) was analyzed using computational fluid dynamics (CFD) simulations by ANSYS Fluent to investigate the chevron‐patterned plates. The influence of geometric parameters, including corrugation pitch, depth, and angle was analyzed.
