Summary: This study examines the photophysical and photochemical properties of silicon and zinc phthalocyanines. Different phthalocyanine compounds were synthesized and characterized to study their concentration and solvent effects. The effects of the metal ion and the position of the substituted group on photodynamic therapy properties were also investigated. The results show that the fluorinated pyrazoline-linked axial silicon phthalocyanine (HY-SiPc) has the highest singlet oxygen production and can be a potential photosensitizer for PDT.

Summary: Highly water soluble Zn(II)Pcs with twelve quaternizable pyridinium groups were designed using pentaerythritol hub. Peripheral and non-peripheral tetra-2,2,2-tris[(pyridin-2-ylthio)methyl]ethoxy-substituted neutral Zn(II)Pcs (4 and 5) were synthesized first, followed by quaternizations of twelve pyridine groups to obtain highly water soluble Zn(II)Pcs (6 and 7). The branched nature of substituted groups prevented aggregation and increased dissolution. The photophysical, photochemical, singlet oxygen-producing properties, and DNA binding behaviors of quaternized Zn(II)Pcs were studied.

Summary: In this study, a scalable and facile method to immobilize long persistent phosphor and photosensitizer onto cotton fabric was reported. The resulting composite material exhibited superior antibacterial activity against Staphylococcus aureus and methicillin-resistant S. aureus under visible-light illumination. Mechanistic studies showed enhanced singlet oxygen production, resulting in effective pathogen inactivation. In addition, the composite fabric possessed excellent abrasion resistance, mechanical strength, and color fastness. These findings suggest the potential of using long persistent phosphors in composite fabrics for infection control applications.

Summary: The study found that despite different calcium carbonate distributions and morphological features, the clay mineral composition in soils developed on menilite shales slope deposits was very uniform, with secondary phases such as chlorite, illite, vermiculite, kaolinite, and mixed phases present in all horizons. This suggests a similar mass movement controlling the slope covers formation and a consistent scale of pedogenesis advancement across all soils. The weak intensity of illuviation process within the homogeneous substrate may have contributed to the uniform composition of clay minerals in the soils.

Summary: Podzolization mainly occurs in soils with highly leached and coarse-textured parent materials under the influence of humid climates where forest or heath vegetation supply enough organic matter to form organic horizons. This study aimed to determine the optimal conditions triggering podzolization in soils in the Bieszczady Mountains in southeastern Poland, with factors such as climate, parent material composition, and vegetation cover influencing the occurrence of Podzols.

Summary: This study aimed to obtain a model of the structure of Mg2+-GLY-smectite/vermiculite through molecular dynamic simulations, considering a wide range of charges and GLY/H2O contents. Relationships between atomic distribution positions and basal spacings were determined to create a simple and flexible model with minimal Gaussian functions. The new model was successfully used to fit diffraction patterns of Mg2+-montmorillonites and Mg2+-vermiculites with different layer charges.

Summary: Climate warming causes environmental changes in the Arctic that affect soil organic matter decomposition and greenhouse gas emissions. A portion of organic carbon and total nitrogen in Arctic permafrost-affected soils is found to be intercalated within swelling clay minerals, showing high resistance to chemical and thermal oxidation. These findings should be considered in climate models and research on permafrost thawing and greenhouse gas emissions.

Summary: This study reveals that surface evolution plays a crucial role in enhancing the electrocatalytic performance of transition metal oxides for electrochemical nitrate reduction reaction (e-NO3RR). Incorporating nickel into Co3O4 can promote surface reconstruction and improve the adsorption of intermediates and reduce energy barriers, leading to enhanced catalytic performance. The reconstructed cobalt-nickel hydroxides (CoyNi1_y(OH)2) on the catalyst's surface serve as the active phase.

Summary: This study explores the discriminative activities and mechanisms for activation of O-O bond in peroxy compounds via single-atom catalysts (SACs) with higher coordination numbers (M-N5). The atomic catalyst (Fe-SAC) with Fe-N5 as the active center was constructed, effectively activating peroxymonosulfate (PMS), peroxydisulfate (PDS), and hydrogen peroxide (H2O2). The study demonstrates the degradation efficiencies of acyclovir are related to the O-O bond length in different peroxy compounds, and reveals the discriminative mechanisms for activation of O-O bond in different Fenton-like systems.
