Modeling the sampling volume for the skin blood oxygenation measurements [PDF]

, 2001
The absolute quantified measurement of haemoglobin skin blood saturation from collected reflectance spectra of the skin is complicated by the fact that the blood content of tissues can vary both in the spatial distribution and in the amount.

Construction of a MOF‐Based Snap‐Top Delivery Nanosystem for Powerful Dual‐Responsive Synergistic Colitis Treatment

Advanced Science, Volume 13, Issue 36, 29 June 2026.
A snap‐top delivery nanosystem based on an azobenzene metal–organic framework achieves targeted release of 6‐mercaptopurine via acid‐stable frameworks and hypoxia/pH dual‐responsive β‐cyclodextrin gates. This multifunctional platform integrates three synergistic mechanisms: precision drug delivery to inflammatory sites, intrinsic antioxidant properties

Stimuli‐Responsive Hydrogels for Optical Applications: Mechanisms, Architectures, and Translational Challenges

Aggregate, Volume 7, Issue 6, June 2026.
The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.

Deciphering pH Behavior in Deep Eutectic Solvents: Synergizing Experimental Data and Computational Modeling

ChemCatChem, Volume 18, Issue 11, 15 June 2026.
Proton activity in deep eutectic solvents (DESs) remains difficult to quantify. Here, pH in hydrophilic and hydrophobic DESs is probed by combining glass electrode measurements with ultraviolet–visible (UV–vis) pH indicators and Gaussian process (GP) machine learning (ML).

Resonant metamaterial absorbers for infrared spectral filtering: quasimodal analysis, design, fabrication, and characterization

, 2014
International audienceWe present a modal analysis of metal-insulator-metal (MIM)-based metamaterials in the far infrared region. These structures can be used as resonant reflection bandcut spectral filters that are independent of the polarization and ...

Synergistic Enhancement of Photocatalytic Nitrate Reduction Over Fe‐Doped Bi/Bi2WO6 via Lewis Acidic Sites and Surface Plasmon Resonance

ChemCatChem, Volume 18, Issue 12, 26 June 2026.
The enhanced photocatalytic nitrate‐to‐ammonia conversion over H‐Fe‐B/BWO can be summarized as a cooperative process involving surface reaction chemistry and charge‐carrier dynamics. Fe dopants introduced into the Bi2WO6 lattice generate coordinatively unsaturated metal centers, which function as Lewis acidic sites capable of strongly interacting with ...

Formation and Characterization of Insoluble Anthocyanins‐λ‐carrageenan Biopolyelectrolyte Complexes: Structural Morphology, Thermal Stability, and Release Dynamics

ChemFoodChem, Volume 2, Issue 2, June 2026.
Insoluble biopolyelectrolyte complexes formed between blackberry anthocyanins and λ‐carrageenan are investigated. Optimal complexation occurs at low carrageenan ratios and acidic pH, producing porous hydrogel‐like structures with enhanced thermal stability.
