Summary: SrMoO4: Sm3+ phosphors with orange red-emitting properties were synthesized using a solid-phase method for temperature measurement applications. The phosphors had a scheelite structure belonging to the tetragonal system and I41/a space group. Sm3+ ions were successfully incorporated into the SrMoO4 lattice. The phosphors exhibited irregular microparticles with well-crystallized pomegranate seed-like morphology, and Sm3+ ions were evenly distributed in the SrMoO4 matrix. The appropriate quenching concentration of Sm3+ was found to be 1.0%, and the phosphors showed excellent thermal stability and anti-thermal quenching properties. A new dual-model thermometry strategy based on exponential function and modified Boltzmann population distribution was proposed, and the phosphors demonstrated absolute sensitivities of 0.108 K-1 and relative sensitivities of 0.601% K-1. The findings highlight the potential applications of SrMoO4: Sm3+ phosphors in pc-WLEDs and optical thermometry.

Summary: Nanomaterials have unique properties that make them highly attractive, and various solution fabrication methods have been developed for synthesizing metal and metal oxides nanoparticles. However, solid-state methods for obtaining nanomaterials are relatively scarce. This review discusses current solid-state methods and introduces a new general method for obtaining nanomaterials. By using macromolecular complexes as precursors, nanoparticles of metals and metallic oxides can be obtained via solid-state pyrolysis. The size and morphology of the nanoparticles depend on the polymer and metal arrangement. The paper also highlights the applications and challenges in this field.

Summary: The treatment of real or synthetic industrial effluents and the study of photocatalysts have attracted a lot of attention from scientists. Among various metal oxide photocatalytic materials, narrow bandgap compounds are particularly significant for their suitable efficiency in optical applications. In this study, pristine ErVO4 was synthesized using the microwave-assisted method, with different solvents and power intensities employed for size and shape control. The properties of the samples, including phase purity, surface area, magnetic and optical features, were analyzed. Microwaves with a power of 900W and ethylene glycol solvent were found to be optimal conditions for generating uniform nanosized particles. The nanostructured ErVO4 was used as a catalyst for the decolorization of colored pollutants, showing high photocatalytic efficiency in experiments with different dye concentrations and catalyst loadings.

Summary: This study successfully synthesized magnetic Fe3O4 nanoparticles using co-precipitation method with ferric chloride and ferrous sulphate as starting materials. The shape and size of the nanoparticles were controlled by using different additives. The results showed that spherical nanoparticles with uniform size were obtained when ammonium hydroxide was added, while cubic nanoparticles were obtained with the addition of sodium hydroxide. Both samples exhibited ferromagnetic behavior, but cubic Fe3O4 nanoparticles had higher adsorptive behavior towards Congo red due to enhanced magnetic properties.

Summary: We present a method for fabricating silicon micro-nanostructures of various shapes by manipulating the number and size of self-assembled polystyrene beads as a mask and adjusting the reactive ion etching time. This approach offers a simple, scalable, and cost-effective solution without requiring sophisticated nanomanufacturing equipment. The demonstration of this method includes the fabrication of silicon micro- or nanoflowers, micro- or nanobells, nanopyramids, and nanotriangles using polystyrene beads as a mask, as well as the creation of flexible micro- nanostructures using silicon molds. Furthermore, we showcase the fabrication of bandage-type electrochemical sensors for detecting dopamine in artificial sweat, indicating the potential of this method for developing wearable micro-nanostructure-enabled sensors.

Summary: This study investigates the influence of channel shape on water transport through graphene channels using molecular dynamics simulations. The results show that the water flux increases monotonously when the channel shape changes from two-dimensional to three-dimensional, due to the reduction in water translocation time, and this is consistent with the calculation by the Navier-Stokes equation.

Summary: Through studying the transmission behavior of photonic topological modes through different shapes of topological microwave channels, we found that topological modes with different intensity of up and down pseudospin can be excited in one channel, providing different transmission ratios between opposite directions. These results suggest a spin-flip process may occur at the exit end face or sharp bending position of the topological channel.
