Summary: Incorporating suitable lanthanide ions into semiconducting WO3 enables host-sensitized luminescence for solid-state lighting applications. Codoping with additional lanthanide ions assists in transferring energy to produce bright luminescence based on the electronic structure of the doped system. The role of Tb3+ ions as a sensitizer to facilitate emission from Eu3+ ions has been investigated, leading to the development of a white-light-emitting phosphor with optimized doping concentrations.

Summary: This study constructed hyperspectral monitoring models of total flavonoids content and total phenols content in tartary buckwheat grains based on different preprocessing spectra. The results showed that the different preprocessing methods had different effects on the spectral reflectance, and fractional-order derivative (FOD) could reflect the change process from the original spectrum to the integer-order derivative spectrum. The monitoring models achieved the best accuracy under certain transformation spectra. The models can realize the rapid measurement of total flavonoids content and total phenols content in tartary buckwheat grains.

Summary: In this study, the oxidation of acetylsalicylic acid (ASA) and salicylic acid (SAL) was carried out using different oxidizing agents. The presence of terbium (III) or europium (III) ions in the Fe(II)/(III)-H2O2-ASA (or SAL)-Ln (III) system acted as sensitizers of the chemiluminescence studied. The Fe(II)/(III)-H2O2-ASA-Tb(III) system showed the highest chemiluminescence intensity, with a linear dependence on the concentration of ASA.

Summary: This study introduces a novel, inexpensive fluorescent biosensor based on terbium chloride to directly quantitate DNA damage induced by epirubicin and investigate the underlying molecular mechanisms of damage. The results show that in the presence of dithiothreitol, epirubicin has a slower DNA damage kinetics but more potent damaging effect on DNA compared to when dithiothreitol is not added. This suggests a potential alternative anticancer therapy that requires further investigation.

Summary: The solubility of mesalazine in binary mixtures of propylene glycol (PG) + 2-propanol was determined using a shake flask method followed by UV-Vis spectroscopy method. The maximum solubility was obtained in neat PG (x(m )= 4.57 x 10(- 4)) at 313.2 K and the minimum solubility in neat 2-propanol (x(m )= 6.32 x 10(- 5)) at 293.2 K. Mathematical cosolvency models were used to predict the solubility of mesalazine in the selected binary mixtures, with deviations of back-calculated data from experimental values (< 4.0%), indicating the applicability of the models.

Several cosolvency models, including van't Hoff, the lambda h equation, the Yalkowsky, the Jouyban-Acree, and the Jouyban-Acree-van't Hoff models, were used to mathematically represent the solubility profile. The performances of these models were evaluated based on mean relative deviations. Moreover, the density values of saturated solutions of ketoconazole were determined and modeled using the Jouyban-Acree model.

Summary: This study explores the use of L-tartaric acid, ascorbic acid, and L-carnitine as alternative agents to enhance the water solubility of baclofen. Co-crystallization experiments were conducted using different stoichiometric ratios and confirmed using XRD, DSC, and FT-IR. The new compounds showed significantly higher solubility than the physical mixtures, indicating the formation of a new crystal phase. However, the co-crystallization of baclofen and L-carnitine did not lead to improved solubility.

Summary: The current study investigates the solubility data and thermodynamic properties of codeine phosphate in mixtures of N-methyl-2-pyrrolidone and 1-propanol under atmospheric pressure at 293.2-313.2 K. The solubility was found to be positively correlated with temperature and N-methyl-2-pyrrolidone ratio. Mathematical models were used to correlate the measured data, and their reliability was assessed through the mean relative deviations of the back-calculated values. The density values of codeine phosphate saturated solutions were also measured and correlated using the Jouyban-Acree model. Additionally, the apparent thermodynamic properties of codeine phosphate solubilisation were calculated based on Gibbs and van't Hoff equations and reported.

Summary: A fluorescence off-on system was developed for uric acid analysis in urine using fluorescein, H2O2, and gold nanoparticles (Au NPs). The system showed quenched fluorescence in the presence of Au NPs and H2O2, but restored fluorescence when uric acid was added due to its interaction with H2O2. The system exhibited linear dependence on uric acid concentration in the range of 0.3-8.0 μg.mL(-1), with a detection limit of 0.12 μg.mL(-1). The results compared to a standard method showed high compatibility and potential for uric acid analysis in urine samples.

Summary: This study investigates the variations in lipid digestion profiles among individuals of different ages using in vitro digestion models. The findings suggest that adults have a more comprehensive lipid digestion compared to infants, and infants tend to release shorter chain length and more saturated free fatty acids during digestion. Additionally, the particle sizes in the stomach of the elderly were consistently larger. This study enhances our understanding of how lipids with different degrees of unsaturation undergo digestion in diverse age groups.

Summary: This study investigated the acidification of aroma-enhanced black tea during storage. Analysis of non-volatile substances and organic acids using UPLC-Q-TOF/MS and HPLC revealed a decrease in soluble sugars and amino acids, while an increase in organic acids such as oxalic acid, malic acid, and quinic acid. In vitro experiments further demonstrated that the acidification is a result of the decomposition of sugars and amino acids by heating, as well as the oxidation of aromatic aldehydes. Additionally, the study showed that the taste composition of tea infusion is altered, with reduced amino acids, catechins, soluble sugars, and flavonoids. This research provides a theoretical basis for improving the quality of black tea.
