Summary: The study developed water-soluble polymer sensors by modifying the structure of BODIPY to create polymerizable fluorescent monomers, which were copolymerized with MAA to form highly sensitive sensors for Fe3+ recognition. Even with low BODIPY content, the sensors exhibited a low detection limit, with those containing two recognition groups per BODIPY unit showing higher sensitivity.

Summary: In this study, activated nanoclusters were prepared through controlled ligand removal in the gas phase using an ion soft-landing instrument. It was found that nanoclusters with one ligand removed showed selective dimerization on self-assembled monolayer surfaces, while nanoclusters with two ligands removed underwent nonselective reactions and formed larger fused clusters. This study reveals the potential of using fragment ions for activating and depositing nanoclusters.

Summary: The development of a PET membrane with multiple biomimetic nanochannels for the detection of fluoride and chromium (III) ions is described. The membrane was created using an asymmetric chemical etching technique and was modified with specific recognition compounds for F- and Cr3+. The method showed excellent linear relationships between current values and ion concentrations, with low detection limits of 4.10 nM for Cr3+ and 0.46 nM for F-. The accuracy and reliability of the method were compared to conventional ICP-MS analysis and showed good agreement, demonstrating its potential application for detecting a wide range of ionic contaminants.

Summary: Synthetic NaX zeolite exhibited selective adsorption capacity towards heavy metal ions, with Pb2+ and Cu2+ showing higher affinity due to their higher electronegativity, impacting the stability of the framework. The negatively charged O in the Si-O-Al structure of NaX zeolite played a key role in the selective adsorption mechanism for high electronegative metal ions, resulting in a strong affinity. This study evaluates the potential application and efficiency of zeolite in separating and recovering specific metal ions from industrial wastewater.

Summary: In recent decades, great attention has been paid to the development of biobased hydrogel nanocomposites (HNCs) for the removal of metal ions from wastewater. This study demonstrates the fabrication of a nanohybrid using modified cellulose nanofiber and zinc oxide nanoparticles, which is then incorporated into a starch/itaconic acid/acrylic acid-based hydrogel matrix. The resulting HNCs show remarkable adsorption ability for metal ions (Cu(II) and Fe(II)). The incorporation of the nanohybrid enhances the metal ion adsorption capacity and the HNCs can be easily removed and reused.

Summary: Three metal-organic frameworks were synthesized using lanthanide ions (Eu3+ for 1, Tb3+ for 2, Dy3+ for 3) and a thiophenethio-functionalized linker. Among them, 1 showed the highest enhancement of photo-luminescence towards Ag+ ions, attributed to the strengthened 'antenna effect' after introduction of Ag+ ions. This study represents the first example of using Eu3+ ions as nodes and thiophenethio-functionalized linkers for selective sensing of Ag+ ions in Ln-MOFs.

Summary: A study has shown that a photoswitchable ligand and palladium(II) ions can form dynamic metallosupramolecular structures. By irradiating with light, the distribution of isomers in the ligand can be controlled, resulting in selective disassembly and formation of stable structures. This approach provides a new strategy for reversible control of self-assembled structures.

Summary: In this study, it was found that mutating a highly conserved threonine residue in CYP199A4 to glutamate can convert it to a peroxygenase and improve its peroxygenase activity. The crystal structure of the mutant demonstrated a change in spin state upon substrate binding, which was linked to the modification of the oxygen-binding groove and the retention of the iron-bound aqua ligand. The detailed characterization of this engineered heme peroxygenase will aid in the development of new methods for the selective C-H bond activation using heme enzymes.

Summary: Recent advances in mass spectrometry (MS) have allowed for the measurement of multiple molecules in single cells. This is crucial for understanding the molecular heterogeneity and function of individual cells. In this review, we discuss different methods of single-cell MS, including high-throughput, targeted, mass cytometry-based approaches, and antibody-free methods, for detailed profiling of the proteome and metabolome of single cells. We also explore the advantages and disadvantages of these methods and the challenges and opportunities for further improvements in single-cell MS. These methods have found applications in biomedical research, such as revealing tumor heterogeneity and conducting high-content drug screening.

Summary: A photoswitchable ligand based on azobenzene is self-assembled with palladium(II) ions to form a [Pd-2(E-L)(4)](4+) cage. Irradiation with 470 nm light results in the nearly complete transformation to a monomeric species [Pd(Z-L)(2)](2+), which can be reversed by irradiation with 405 nm light or heat. Self-assembly significantly improves the photoswitching selectivity and extends the thermal stability.

Summary: Sebum from sebaceous glands is a rich source of volatile organic compounds (VOCs) that can be sampled non-invasively from the skin surface. However, there is a need to establish the effects of sampling approaches and environmental factors on sebum VOC profiles. In this study, a more standardized skin swab sampling approach was investigated, and the impact of sampling materials and preparatory conditions on VOC profiles was assessed using thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS). The study highlights the importance of rigorous controls in sebum sampling and provides recommendations for future research.

Summary: Theta capillary nanoelectrospray ionization (theta-nanoESI) can be used to supercharge protein ions directly from solution for detection by mass spectrometry (MS). The mechanism for theta-nanoESI mixing has been reported to primarily occur via droplet fusion rather than in the Taylor cone prior to ESI droplet formation. This method allows for the formation of highly charged protein ions with more elongated structures.

Summary: We demonstrate a new approach to constraining rate coefficients in complex chemical reaction mechanisms using master equation modeling with genetic algorithm optimization. The approach is applied to low-temperature cyclopentane oxidation and yields temperature-dependent rate coefficients with associated uncertainties. The optimized sub-mechanism, combined with a comprehensive cyclopentane combustion mechanism, shows good extrapolation to higher temperatures.

Summary: Guided ion beam tandem mass spectrometry was used to study the reactions of U+ with O-2 and CO. The formation of UO+ in the U+ + O-2 reaction is barrierless and exothermic, with a reaction efficiency that increases with higher collision energies. Both the formation of UO+ and UC+ in the U+ + CO reaction are endothermic. Analysis of the kinetic energy dependent cross sections reveals 0 K bond dissociation energies of D-0(U+-O)=7.88 +/- 0.09 eV and D-0(U+-C)=4.03 +/- 0.13 eV, which are consistent with previous experimental values. Quantum chemical calculations were also performed to explore the electronic states of UO+ and UC+ and the potential energy surfaces for the reactions, yielding further insights into the reaction mechanisms. The experimental bond dissociation energies are found to be similar to those of transition metal congeners.
