Photochemical Surface Degradation in Spiropyran Based Films

open access: yesChemPhotoChem, Volume 9, Issue 6, June 2025.
Monitoring of photoswitching surface properties using molecular photochromes can give misleading results due to primary inner filter effects. The surface layer can degrade but then protect deeper layers from damage, leading to misassignment of the origin of light driven changes in surface energy.

Food Waste to Wellness: A Grape Pomace Blend in Gastric Cancer Prevention

open access: yesFood Science &Nutrition, Volume 13, Issue 6, June 2025.
Grape pomace was used to set up a phytocomplex studied for gastric cancer prevention. HPLC/MS analyses revealed that this mixture is a source of many polyphenols and amino acids. This novel nutraceutical (GPE) selectively targets cancer cells, sparing healthy ones. Molecular mechanisms confirmed that GPE acts, inducing apoptosis and autophagy.

Combining Selective Laser Sintering and Fused Deposition Modeling of Pharmaceutical Polymers: A Novel Approach to Prepare Intestine‐Targeted Tablets

open access: yesMacromolecular Materials and Engineering, Volume 310, Issue 6, June 2025.
Selective laser sintering (SLS) and fused deposition modeling (FDM) are combined to prepare intestine‐targeted tablets with controlled drug release. The SLS‐printed core contains a model drug. The FDM‐printed coating shell modifies drug release and increases tablet mechanical resistance.
