Summary: The growing population has caused an increase in water contamination, prompting the development of an efficient and eco-friendly catalyst to remove pollutants from water bodies. This study presents the development of a Sm-doped Fe2O3 photocatalyst through a low-cost sol-gel route for degrading methylene blue under sunlight. Various characterizations were conducted to analyze the photocatalyst, confirming the successful doping of Sm and the enhanced photocatalytic performance attributed to structural variations and efficient charge carriers separation/transportation. The synergistic photocatalytic performance of the doped catalyst proves its potential in water remediation.

Summary: This investigation examines the differences in fluorescence behavior of dyes with various nitro substituents. The presence of the NO2 group significantly enhances fluorescence intensity at 298 K. Methylene green (MG) exhibits a non-radiative process where the excitation energy migrates to triplet states, resulting in absence or low fluorescence compared to methylene blue (MB). However, at liquid nitrogen temperature, MG shows significantly higher fluorescence and phosphorescence in ethanol. Similarly, MB exhibits a six-fold increase in fluorescence intensity at 77 K in ethanol. The study reveals different lifetimes in the excited state for each dye in various solvents. Additionally, MG exhibits phosphorescence at 780 nm in ethanol and at 810 nm in chloroform.

Summary: In this study, two new phenothiazinium dyes with N-piperidinyl-carbinol auxochrome units were designed, synthesized, and evaluated for fluorescence imaging and cytotoxicity in ovarian cancer cells. A solvent-free mechanochemical method was used for the synthesis of the dyes, providing a greener alternative to the traditional solution-based synthesis. The optical properties of the dyes were characterized by UV-vis absorption/emission spectroscopy, showing red-shifted absorption and emission peaks in more polar solvents. Theoretical DFT calculations were performed, and the results were in good agreement with the experimental data. The new dyes exhibited hydrophilic properties and showed selective staining of the cytoplasm of tumoral cells. They also displayed moderate cytotoxicity against ovarian cancer cell lines, with one of the dyes showing a deeper influence on the function of chemoresistant cells.

Summary: Anionic drugs atorvastatin and valsartan were successfully intercalated into Mg-Al LDH host with high drug loading. XRD analysis confirmed the intercalation of both drugs, while molecular modeling showed the interaction between drugs and LDH at the atomic scale. Experimental measurements supported the findings from the modeling, indicating weak electrostatic interactions between LDH layers and drug molecules. The release of the drugs from the intercalated LDH slightly differed in different media, following pseudo-second-order kinetics.

Summary: The aim of this work was to construct maps of anthropogenic contamination of agricultural soils in Czech Republic by risk elements. Conventional approaches to geochemical maps can only visualize extreme contamination, while weak and/or diffuse contamination requires expert opinion to distinguish natural and anthropogenic factors. Geogenic and lithological anomalies play important roles in understanding contamination sources. Element concentration ratios, such as Co, Cu, Pb, and Zn, can be used to separate geogenic and lithogenic anomalies. Expert opinion is necessary to distinguish anthropogenic contamination from natural variability. The interpretation of geochemical maps and identification of anthropogenic contamination become more complicated in larger and more heterogeneous mapped areas.

Summary: Diamond thin films with a high-density of light-emitting negatively charged silicon vacancy (SiV) centers can be prepared at a relatively low cost, which has potential applications in photonics or sensing. The composition of the films, which consist of diamond grains with SiV centers and sp(2)-carbon phase, can be adjusted by changing the preparation conditions. Surface defects and the sp(2)-related defects in the grains can trap the carriers excited within the SiV centers, leading to a decrease in their internal photoluminescence (PL) quantum efficiency.

Summary: This paper reports on the enhancement of high harmonic generation (HHG) yield using a metasurface made of amorphous silicon disks. The structure was designed and optimized to achieve a 20-fold enhancement compared to an unstructured surface. A broadband magnetic resonance mode enhanced the local field, allowing the use of ultrashort laser pulses as short as 40 fs. Due to the anisotropic structure of the metasurface, both the local-field enhancement and the HHG yield exhibit strong polarization anisotropy.

Summary: This review summarizes research articles on the photocatalytic fixation of nitrogen using graphitic carbon nitride (g-C3N4) from 2015 onwards. The NH3/NH4+ production rates from these articles were statistically processed, with the highest rate achieved by the composite g-C3N4 and 1T-MoS2 being 11120 mu mol g(-1) L-1 h(-1). The highest reported rate provided by bulk g-C3N4 was 5561 mu mol g(-1) L-1 h(-1), which surpassed 90% of the rates from various g-C3N4 composites. The quantum efficiency of the composites ranged from 0.033 to 5.65% with a median of 1.25%. Although not competitive with the industrial Haber-Bosch process, graphitic carbon nitride shows promise for future investigations into photocatalytic nitrogen fixation under visible light.

Summary: This study searched for an empirical relationship between the number of review and research articles published per year. The simple idea based on proportionality between the numbers of both kinds of articles was expressed using a quadratic relationship that accounts for negative or positive deviations from assumed linearity. The quadratic relationship was able to accurately describe the early and mature phases of research fields and detect unexpectedly high numbers of review articles. The findings were verified using articles from 20 different research fields across various time spans obtained from the Web of Science.

Summary: In this study, the ultrafast dynamics of valley-polarized excitons in monolayer WSe2 were experimentally investigated using transient reflection spectroscopy with few-cycle laser pulses of 7 fs duration. It was observed that at room temperature, the anisotropic valley population of excitons decayed on two different timescales. The shorter decay time of approximately 120 fs was related to the initial hot exciton relaxation caused by fast direct recombination of excitons from the radiative zone, while the slower picosecond dynamics corresponded to valley depolarization induced by Coloumb exchange-driven transitions of excitons between two inequivalent valleys.

Summary: Sufficient photochemical stability is crucial for the successful environmental applications of g-C3N4 photocatalyst. This study investigates the photostability of g-C3N4 materials under UV and visible light irradiation, and analyzes the production of organic compounds. The results show that g-C3N4 materials produce organic compounds under UV or visible light, while TiO2 does not. This may be due to the surface oxidation reaction of g-C3N4 materials, which leads to the disruption of C-N bonds and the release of organic compounds.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
