Spouted bed drying parameters and adjuvant effects on polyphenol retention and antioxidant activity in mango peel powders

The Canadian Journal of Chemical Engineering, EarlyView.
Spouted bed drying of mango peels with colloidal SiO2 and corn starch produces a free‐flowing powder with reduced agglomeration, increased drying yield, and preserved antioxidant and polyphenol content. Abstract The production of polyphenol‐rich powders is a promising strategy for valorizing agro‐industrial byproducts. This study evaluated drying yield,

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Double scale analysis of periodic solutions of some non linear vibrating systems [PDF]

, 2013
We consider {\it small solutions} of a vibrating system with smooth non-linearities for which we provide an approximate solution by using a double scale analysis; a rigorous proof of convergence of a double scale expansion is included; for the forced ...

Environmental Policy Without Implementation? A Review of Factors Contributing to Implementation Gaps in Low‐ and Middle‐Income Countries

Environmental Policy and Governance, EarlyView.
ABSTRACT The sound formation of robust environmental policies is increasingly important for low‐ and middle‐income countries (LMICs) to achieve their national objectives and international commitments. However, policy implementation can be complex, and environmental policies may not be prioritised given other critical socio‐economic development issues ...

Robust Control Using a Matrix Converter to Enhance Wind Turbine Systems

Energy Science &Engineering, EarlyView.
This study uses a more efficient and effective solution to improve the operational performance of a wind turbine‐based power system. This system uses a doubly fed induction generator and relies on a matrix converter and fractional‐order proportional–integral controller.

Hybrid Oxygen Enrichment and Preheating Strategy for Performance Recovery in Ultra‐Lean Micro–Trapped Vortex Combustors

Energy Science &Engineering, EarlyView.
Ultra‐lean H2 micro‐combustor performance is boosted through regulated O2 enrichment and inlet preheating. A 16‐case Taguchi study (ϕ = 0.3) shows: controlled enrichment and heating increase radiative output and efficiency, but excessive O2/temperature causes flashback.
