Heterogeneous Copper‐Catalyzed 1,4‐Conjugate Additions of Grignard Reagents to Cyclic and Linear Enones

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
The 1,4‐conjugate addition of Grignard reagents to various cyclic and linear enones using a heterogeneous catalyst is reported. Recyclable copper nanoparticles immobilized on polysaccharide support (e.g., cellulose, chitosan) enable high chemo‐ and regioselectivity.

Polyethyleneimine‐Modified Biosorbent Based on Banana Pseudostem Biomass for Environmental Remediation and Food Analysis

open access: yesAdvanced Sustainable Systems, EarlyView.
Biosorbents derived from banana pseudostem are functionalized with polyethyleneimine, with or without glutaraldehyde, and evaluated for dye removal and solid‐phase extraction. The materials exhibit high adsorption capacities and broad pH applicability in dye removal, while computational studies reveal amino groups as key interaction sites.

Life Factors and Melanoma: From the Macroscopic State to the Molecular Mechanism

open access: yesAdvanced Science, EarlyView.
Melanoma, an aggressive skin cancer, arises from dynamic interactions between genetic, environmental, and lifestyle factors. This review explores how age, gender, obesity, diet, exercise, smoking, alcohol, UV exposure, circadian rhythms, and medications influence melanoma risk and progression.
