Summary: Recent decades have seen significant developments in the research of pure upconversion red emission, which has important applications in bioimaging and anti-counterfeiting. This study achieved a single-band red upconversion emission in the new material beta-Ba2ScAlO5: Yb3+/Er3+ with the assistance of Ce3+ doping. The red to green integrated intensity ratio reached up to 430.9. The doping of Ce3+ ions enhanced the red emitting level of Er3+ while suppressing the green emission. The study investigated the upconversion luminescence mechanism and concluded that energy transfer and cross-relaxation probabilities between Er3+ and Ce3+ ions played a key role in enhancing the red emission. This work provides a valuable insight for the development of new phosphor materials with single upconversion red emission in various fields.

Summary: Composite phosphors Thx(MoO4)2/Bi2(1-x)Mo2O9:2Ho3+/5Yb3+ were synthesized using a facile co-precipitation process in ethylene glycol medium and subsequent calcinations. The phase formation of the dual-phase composite system [Th(MoO4)2-Orthorhombic;/3-Bi2Mo2O9-Monoclinic] was confirmed by Rietveld refinement of XRD patterns and FTIR analysis. The REs ions (Ho3+/Yb3+) showed phase-dependent UV-Vis absorption, and the optical bandgap difference between the phases led to different optical property efficacy. PL emission spectra exhibited strong green, relatively weak red and NIR emissions under λexci= 450 nm, with Yb3+ ions acting as sensitizer for efficient UC emission under 980 nm excitation. Drastic changes in emission intensity (UC/DC) were observed with relative dual-phase variation, attributed to different crystal field scenarios around REs ions. The multifarious properties of these phosphors, including dual mode emission, phase-dependent emission, and color tuning properties, make them suitable for various applications such as biological cell imaging, phototherapy, optical switching, display devices, solar cells, LEDs, etc.

Summary: The surface acoustic wave (SAW) properties of potassium titanyl phosphate (KTiOPO4, KTP) single crystal were evaluated using numerical methods. The phase velocity, electromechanical coupling coefficient, power flow deflection angle, and temperature coefficient of delay (TCD) were determined for different crystal cuts of KTP. It was found that the Z-cut and wave propagation direction along the X + 70 degrees-axis have an electromechanical coupling coefficient of 0.59% and a TCD of 62 ppm/degrees C for SAW, while the Z-cut and wave propagation direction along the X-axis have a pseudo-surface wave (PSAW) characterized by a coupling coefficient of 0.46% and a TCD value of 57 ppm/degrees C. The Bleustein-Gulyaev (BG) wave has TCD values of 35 ppm/degrees C and 41 ppm/degrees C for the Y-cut and X-cut of KTP, respectively.

Summary: The oxidation reactions of BaLaCuS3 in the artificial air atmosphere at different heating rates were studied. The oxidation stages were determined using DSC-TG, XRD, and IR-vis methods. The kinetic characteristics of the reactions were analyzed using the Kissinger model. BaLaCuS3 was stable up to 280°C but underwent three main oxidation stages upon further heating up to 1200°C. The final result of the high-temperature treatment was a mixture of barium sulfate, copper (II) oxide, and La2CuO4.

Summary: The multicomponent reaction of 2-nitroacetophenone, acetaldehyde diethyl acetal, beta-dicarbonyl compound, and ammonium acetate in acetic acid solution yielded 4-methyl-substituted derivatives of previously undescribed 5-nitro-1,4-dihydropyridine. Oxidation of the obtained derivatives resulted in 2,4-dimethyl-5-nitropyridines. This study also introduced the use of acetaldehyde diethyl acetal as a source of acetaldehyde in the synthesis of unsymmetrical 1,4-dihydropyridines, which produced controlled synthesis of unsymmetrical 5-nitro-1,4-dihydropyridines. The proposed multicomponent approach allowed the synthesis of previously undescribed substituted 5(3)-nitropyridines.

Summary: Heavy-metal contaminants are a significant problem in agriculture, threatening food security due to their high toxicity and ability to accumulate in soils and crops. This study aims to develop a consortium of microorganisms isolated from technogenic sites to address soil restoration in agriculture. Promising strains capable of removing heavy metals were selected, and a consortium (Consortium D) consisting of Achromobacter denitrificans, Klebsiella oxytoca, and Rhizobium radiobacter was found to be the most effective. Consortium D demonstrated the ability to produce phytohormones and remove heavy metals from experimental media. Furthermore, the combined use of Trifolium pratense L. and Consortium D improved the efficiency of phytoremediation. Further research will focus on developing a biological product for land remediation in agriculture.

Summary: The vacancy generation dynamics in doped semiconductor heterostructures with quantum dots (QD) formed in the cationic and anionic sublattices of AlAs is investigated. It is experimentally demonstrated that the vacancy-mediated high temperature diffusion is enhanced or suppressed depending on the location of QDs in the heterostructures. A model is developed to explain the doping effect on the vacancy generation dynamics. Additionally, the impact of nonuniform charge carrier spatial distribution on the vacancy generation and diffusion at high temperatures is revealed.

Summary: The study investigates the relationship between various parameters of concrete production process and its properties, such as strength, density, and bending strength, using 48 experimental data points. The results show significant correlations among the compressive strength at different ages, suggesting that predicting only one characteristic is sufficient. Linear regression analysis is not accurate due to the lack of multiple correlations, hence Machine Learning, specifically the Random Forest method, is recommended. The study identifies key parameters for achieving high compressive and bending strengths, including air-entraining additives and specific types of crushed stone fractions.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.
