Photothermal Hydrogel with Mn3O4 Nanoparticles Alleviates Intervertebral Disc Degeneration by Scavenging ROS and Regulating Extracellular Matrix Metabolism

open access: yesAdvanced Functional Materials, EarlyView.
The MPTT‐nanozyme‐hydrogel system (Mn3O4@ChS‐HA) provides a multifunctional therapeutic strategy for intervertebral disc degeneration (IVDD), effectively targeting oxidative stress and enhancing AF repair by restoring extracellular matrix (ECM) and redox homeostasis.

Photochemical UV/TiO2 treatment of olive mill wastewater (OMW) [PDF]

open access: yes, 2008
Olive mill wastewater (OMW) was treated by photocatalysis using TiO2 under UV irradiation on the laboratory scale. The chemical oxygen demand, the coloration at 330 nm, and the level of phenols all showed decreases which, after a 24-h treatment, reached ...

Determination of Phenols in Groundwater by Solid-Phase Membrane Extraction Combined with Ultrasonic Derivatization-negative Chemical Ionization Mass Spectrometry

open access: yesYankuang ceshi, 2014
Due to their strong polarity, phenolic compounds cannot be directly determined by Gas Chromatography-Mass Spectrometry. Derivatization can reduce the strength of the polarity of phenols, and improve the detection sensitivity.

Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations

open access: yesAdvanced Functional Materials, EarlyView.
Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.
