Article Abstract
A morpholine-functionalized pyrrole-cyanine probe was synthesized via a simple condensation reaction in high yield. This probe exhibits high selectivity toward ClO on fluorescence and UV-vis spectra in neat aqueous solution. The strong green emission of the probe solution was quenched and the yellow color faded immediately upon the addition of ClO. The detection limit of the probe for ClO was 0.165 μM. The mechanism of hypochlorite-induced CC breakage was supposed on the basis of EIS-MS, NMR, and density functional theory (DFT) calculation. Finally, the probe was utilized to image ClO in lysosomes of living cells.

Dendrimer-modified carbon nanotubes for the removal and recovery of heavy metal ions from water.

Effective removal of trace heavy metal ions from aqueous bodies is a pressing problem and requires significant improvement in the area of absorbent material in terms of removal efficiency and sustainability. We propose an efficient strategy to enhance the adsorption efficiency of carbon nanotubes (CNTs) by growing dendrimers on their surface. First, CNTs were pre-functionalized with maleic acid (MA) via Diels-Alder reaction in presence of a deep eutectic solvent under ultrasonication.

Background: In catheter-based radiofrequency ablation (RFA), energy is delivered to heterogeneous thin-walled tissues to induce therapeutic heating. Variations in electrical and mechanical properties of tissue contents have a great effect on outcomes.
Purpose: The objective of this study is to develop models that replicate tissue heterogeneity and visualize ablation zones for effective evaluation and optimization.
Determination of alcohol concentration in a single drop blood obtained via fingertip using gas chromatography/mass spectrometry coupled with solid-phase microextraction.

This study investigated headspace solid-phase microextraction (HS-SPME)-gas chromatography (GS)/mass spectrometry as a low-complexity method for accurate measurement of blood alcohol concentration (BAC) changes in humans over time following alcohol consumption. The aim was to develop an analytical method that would require as small blood samples as possible-smaller than that required for the conventional method-thereby reducing the burden on the subject. Polyethylene glycol (PEG) was used as the fiber material for SPME, and a DB-WAX capillary column was used for GC.

Understanding hydrogen bonding and ion-specific interactions in water, sodium sulfate (NaSO), and acetonitrile (ACN) systems remains challenging due to their complex, dynamic nature. Here, Raman spectroscopy is employed to probe hydrogen bonding networks and ion reorganization in NaSO aqueous solutions with different ACN concentrations. The results indicate that, at low ACN concentrations in the ternary solutions, hydrogen bonding between ACN and water molecules disrupts the original hydration structure of the ions, resulting in the formation of small ion clusters via electrostatic interactions.

Cadmium (Cd) contamination in water poses a critical global challenge. A novel nanocomposite, montmorillonite (Mt)-supported nanoscale zero-valent iron (Mt-nZVI), synthesized by liquid phase reduction, offers a promising method for effectively removing Cd. The material underwent characterization through various techniques, including X-ray diffraction (XRD) and Scanning Electron Microscope(SEM).
