Solvent‐Induced Structural Modulation in Nanoscale Covalent Organic Frameworks Enables High‐Performance NO2 Sensing

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Solvent intercalation disrupts the stacking order of protonated porphyrin‐based 2D COF nanoparticles, resulting in a less compactly packed structure with increased accessibility of porphyrin sites. This structural modulation leads to significantly enhanced chemiresistive NO2 sensing performance.

A low‐cost handheld device for monitoring cutaneous photosensitivity

Photochemistry and Photobiology, EarlyView.
The cutaneous photosensitivity detection (CPD) device is a handheld contact‐based measurement device using 405 nm excitation and red fluorescence detection for monitoring skin phototoxicity risk after photodynamic therapy (PDT) procedures involving systemic aminolaevulinic acid (ALA) induced protoporphyrin IX (PpIX) photosensitization.

Soret and dufour impacts on radiative power-law fluid flow via continuously stretchable surface with varying viscosity and thermal conductivity

Scientific Reports
The intricate dynamics of mixed convective thermic and species transport in a power-law flowing fluid through a continuously stretched surface are investigated. The uniqueness of this study lies in the consideration of fluid variable thermic conductivity

Entropy‐Stable and Energy‐Conservative Fully‐Discrete Finite Element Method for Non‐Isothermal Phase‐Field Models

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT This work presents a conforming finite‐element scheme for non‐isothermal phase‐field systems coupled to the incompressible Navier–Stokes equations. The proposed numerical scheme preserves entropy production and total energy conservation exactly by variable transformations using entropy as the main variable instead of temperature.

Encapsulation of Porphyrins in Polymer Microgels and Microbeads for Heterogeneous Photooxidation

ChemSusChem, Volume 19, Issue 19, 14 October 2026.
Amino‐ or ammonium‐functionalized tetraphenylporphyrins were synthesized and encapsulated within polymers to form microgels and microbeads that act as heterogeneous photocatalysts. Photooxidation in aqueous media quantitatively converts sulfides and aldehydes into sulfoxides and carboxylic acids via the singlet‐oxygen pathway, demonstrating an ...

Linear stability analysis on the onset of Soret-driven motion in a nanoparticles suspension

, 2011
The onset of Soret-driven instability in binary mixture heated from above is analysed using the linear stability theory. The horizontal fluid layer placed between two plates is in a thermally stable state but the Soret diffusion can induce buoyancy ...
