Summary: This study demonstrates that the enhancement of orange-light luminescence of Mn-doped zinc sulfide nanoparticles induced by exposure to UV light is due to lattice-strain effects rather than passivation effects. UV irradiation in air causes surface oxidation on the nanoparticles, resulting in mechanical strains between the outer crystallographic metal sulfate lattice and the inner sulfide lattice, ultimately affecting the electronic transition processes and leading to increased emission intensity.

Summary: Iron-doped zinc sulfide thin films were synthesized by chemical bath deposition with different Fe dopant concentrations. XRF analysis showed the doped films to be zinc rich and sulfur poor, and the crystalline quality and optical performance were found to be related to the Fe dopant concentration, with the sample doped 6 at.-% Fe showing the best performance. Photoluminescence intensity was also found to be very sensitive to the rise of iron concentration.

Summary: The conversion processes of sugarcane generate a large amount of waste called sugarcane bagasse. This study proposes a zero-waste pathway to turn sugarcane bagasse into high added-value functional materials. By macerating and ultrasonication, a natural extract was obtained and used as a bio-reducing medium. Then, the sugarcane bagasse was impregnated with a bimetallic solution to produce a composite and carbonized to fabricate biochar, while residual liquid waste was used to obtain free nanoparticles. The biochar showed high catalytic activity and the nanoparticles exhibited exceptional effects against certain protozoans.

Summary: The effect of doping with Co2+ and Sn4+ on the properties of Ba0.5Sr0.5Fe12-2xO19 hexaferrite was investigated. The structure and microstructure of the samples were analyzed using XRD and SEM, while impedance spectroscopy was used to measure the dielectric properties. The results showed that the doping decreased the dielectric constant and loss tangent, and the impedance decreased with increasing frequency. An electrical equivalent circuit was proposed to explain the observed properties. The non-doped sample (x = 0.0) was found to have the best values for antenna applications.

Summary: The relationship between surface composition, graphitization degree, particle size, and catalytic activity of copper-nickel alloy decorated mandarin peel biochar at different pyrolysis temperatures was investigated. The samples prepared at 300°C exhibited the highest graphitization degree with the presence of CuNi alloy and NiO on the surface. In contrast, the samples prepared at 500°C and 700°C only contained the bimetallic alloy. The 300°C sample showed the highest catalytic activity in the oxidative degradation of Methylene Blue.

Summary: N-doped carbon quantum dots/Zn0.4Co0.6Fe2O4 (N-CQDs/ZnCF) composite was synthesized via hydrothermal method. Characterization techniques including XRD, HR-TEM, UV-Vis/DRS, PL, and XPS were utilized. The synthesized nanomaterials exhibited band gap energies less than 2 eV. Improved separation efficiency of photo-generated carriers was confirmed on N-CQDs/ZnCF by PL analysis. Both N-CQDs and ZnCF showed quasi-spherical and cubic morphology, respectively, as observed by HR-TEM. XPS analysis of 10% N-CQDs/ZnCF confirmed the presence of Zn2+, Co2+, Fe3+, N, O, and C on the composite surfaces. Photodegradation of oxytetracycline under visible light irradiation was tested for pristine NPs and N-CQDs/ZnCF NCs, with the 10% N-CQDs/ZnCF nanocomposite exhibiting the highest photocatalytic activity of up to 98% in 100 min. This enhancement was attributed to the synergistic effect of N-CQDs and ZnCF in the heterojunction, promoting charge carrier separation and boosting photoactivity in degrading OTC.
