Summary: The effect of excitation power density on K-SV measurement is theoretically analyzed and experimentally studied using PdOEP as an example. The real KSV of PdOEP is determined to be 58 +/- 2 kPa(-1), which is verified through the analysis of oxygen-dependent phosphorescence lifetimes and IP.

Summary: The poly(caprolactone) was modified with a thin nanocomposite layer consisting of organoclay and photoactive dye, PhB. Electron microscopy, water contact angle measurements, X-ray diffraction, and various spectroscopies were used to characterize the surface properties and composition of the nanocomposite layer. The films exhibited photoactive and antimicrobial properties.

Summary: In this study, a carboxylic acid-based deep eutectic solvent was synthesized and used for removing diclofenac from water. The designed solvent system achieved an approximate 80% removal of diclofenac and was influenced by factors such as initial concentration, solvent level, and temperature.

Summary: Benzopyran nitrile dyes, with low quantum yield of triplet state, are not suitable as qualified photosensitizers. This study successfully prepared a series of selenium-containing photosensitizers using the heavy atom effect, and demonstrated their ability to produce efficient fluorescent signals and light-induced therapeutic effects under laser irradiation. These selenium-containing photosensitizers exhibited excellent biocompatibility and phototoxicity, making them promising agents for NIR fluorescence imaging and photodynamic therapy.

Summary: This study presents a novel non-electrophoretic, electric field-based separation mechanism that can transport ions based on their dielectric properties. While similar to dielectrophoresis, this polarization-based mechanism is remarkably more efficient at small length scales compared to any dielectrophoretic separation mechanism for particles. The concentration change of the working solute, sodium fluorescein, is shown to decrease by approximately 20% in an electric field region compared to a non-electric field region with an applied electric field strength as low as 0.75 MV m(-1) across a 100 μm channel. Existing macroscopic theoretical models such as electrohydrodynamics and equilibrium thermodynamics underestimate the concentration change by two orders of magnitude for the same electric field strength, suggesting a missing key physics in the electric field-based equilibrium thermodynamic model.

Summary: A theoretical-computational procedure based on the quasi-Gaussian entropy theory and molecular dynamics simulations is proposed. It can construct an analytical model of the most relevant thermodynamic properties within a wide temperature range by automatically sampling the entire conformational repertoire of highly flexible systems. The method's reliability mainly depends on the quality of the force field used in the simulations and the ability to distinguish between semi-classical and quantum degrees of freedom in a physically coherent way.

Summary: In this study, phenalenone derivatives were synthesized with electron-donating groups to red-shift the absorption spectrum, and bromine(s) were added to enhance singlet oxygen production via the heavy-atom effect. Among the derivatives, OE19 showed the longest absorption wavelength, green fluorescence, and efficient singlet oxygen production, demonstrating potential for photodynamic cancer therapy.
