Evolution of Pigments in Artificially Aged Polyethylene Plastics: A Raman Study

Journal of Raman Spectroscopy, EarlyView.
The evolution of specific pigments included in plastics exposed to UVA is studied using Raman spectroscopy. This approach is applicable to both organic and inorganic pigments and is facilitated by resonance mechanisms. ABSTRACT The degradation mechanisms of polymers under UV exposure and the evolution of additives are a major concern due to their ...

Dietary impact of agri‐food by‐products on the volatile composition of Tenebrio molitor larvae

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Incorporating Tenebrio molitor larvae as ingredients in common foods is a promising strategy to encourage their consumption. To achieve this, knowing their volatile profile and the factors that may modify the profile is essential. The effect of larval feeding over volatile composition remains under‐researched, for this reason; the ...

Advancing Therapies for Mycobacterial Diseases: From Small Molecules to Host‐Directed Strategies

Medicinal Research Reviews, EarlyView.
ABSTRACT The global burden of multidrug‐resistant tuberculosis (MDR‐TB) and the rising incidence of nontuberculous mycobacterial (NTM) infections highlight the urgent need for innovative therapeutic strategies. Current treatments are prolonged, toxic, and increasingly compromised by resistance and limited diagnostic capacity.
