Summary: This experimental work investigated undoped and Dy-doped MoO3 nanobelts with different doping concentrations synthesized via hydrothermal route. The influence of Dy dopant contents on structural, morphological, elemental, functional, and optical properties of MoO3 nanobelts was studied. The results showed that Dy doping affects the microstructural, morphological, and optical characteristics of MoO3 nanobelts, while having minimal impact on morphology.

Summary: In this study, pure and Fe-doped h-MoO3 microrods were successfully synthesized via the hydrothermal method. Different characterization techniques were used to analyze the resulting products. The addition of Fe dopant did not significantly change the lattice parameters of h-MoO3, but increased the particle size. The photocatalytic performance of Fe-doped h-MoO3 first increased and then decreased with increasing amount of Fe dopant. NH4+ and OH- played important roles in the formation of h-MoO3 microrods.

Summary: In this experiment, the effects of different reactions on the growth process and morphology of h-MoO3 and a-MoO3 were investigated. The optical properties and photocatalytic activities were also studied. The results showed that the morphology of h-MoO3 was influenced by the amount of ammonium molybdate tetrahydrate (AHM), the type of acid, the reaction temperature, and the holding time. The samples produced by the microwave hydrothermal method had sharp diffraction peaks and high crystallinity. The spherical sample A11 showed excellent adsorption and photocatalytic activity.

Summary: In recent years, semiconductor photocatalysts have been widely used to eliminate emerging wastewater contaminants under visible light. However, the large bandgap energy and fast charge recombination pose challenges in practical applications. This study explores the excellent photocatalytic activity of Co3O4/MoO3 nanocomposites in degrading rhodamine B and alizarin yellow dyes. The p-n heterojunctions formed between p-Co3O4 and n-MoO3 significantly enhance the visible light photocatalytic performance, with 91% RhB removal and 67% AY removal after 120 minutes of visible light exposure.

Summary: Ammonia gas sensors utilizing aligned one-dimensional orthorhombic molybdenum trioxide (α-MoO3) nanorods demonstrated high sensitivity and stability at room temperature, with the sensors annealed at 400 degrees Celsius showing response to lower concentrations of ammonia. The morphological and structural changes of α-MoO3 nanorods after annealing contributed to the improved sensing response.

Summary: A highly fluorescent ZnS-encapsulated flexible nanocellulose was synthesized using a two-step hydrothermal route. Structural studies confirmed the presence of hexagonal wurtzite (WZ) ZnS in the nanocellulose. The nanocomposite exhibited a bright ring spot pattern in selected area electron diffraction. The luminescence intensity was found to be higher in ZnS10 and lower in the other nanocomposites, attributed to the density of free sites or defects on the surface of the particles and crystallinity. The nanocellulose showed maximum UV absorption in the range of 290-310 nm, indicating strong photoactivity in the UV region due to the quantum confinement effect of semiconductor NPs.

Summary: The article investigates the processes occurring during the molecular-beam deposition of germanium layers on Si3N4 dielectric substrates within a wide range of temperatures. It is found that IR absorption bands related to vibrations of N-H and Si-N bonds decrease with increasing Ge deposition temperature, while peaks corresponding to Ge-N and Ge-O vibration bonds emerge in X-ray photoelectron spectra. Experimental results suggest diffusion of hydrogen atoms from the Si3N4 layer into the growing Ge film, triggering diffusion of germanium atoms in the opposite direction.

Summary: In this study, an efficient and green method for the preparation of hydrophobic optically transparent wood is proposed. The method involves removing lignin chromogenic groups from natural wood, immersing the wood substrate template with epoxy resin, and modifying the surface with PDMS low surface energy. The resulting hydrophobic optically transparent wood exhibits 93% light transmission, 85% haze, and a contact angle of 150 degrees. Scanning electron microscopy and chemical composition analysis confirm the successful infiltration of epoxy resin into the internal pores of the wood, forming a homogeneous interface with the wood cell walls. This preparation method effectively produces a new wood composite alternative material with excellent optical and hydrophobic properties, which has potential applications in energy-efficient buildings, smart windows, and solar cells.
