Summary: In this study, hierarchical and hollow microspheres assembly of one-dimensional zinc-trimesic acid (Zn-BTC) MOF nanospikes were successfully synthesized using a single step solvothermal synthesis method. The formed Zn-BTC hierarchical and hollow microspheres were annealed to form ZnO/C hierarchical nanocomposite microspheres. These hierarchical nanocomposite microspheres exhibited enhanced photocatalytic activities for water remediation. The improved photocatalytic performance was attributed to the synergistic effect between the carbon matrix and well-dispersed ZnO quantum dots.

Summary: A one-step approach is developed for the decoration of CdTe QDs onto the surface of GO nanosheets/integration of QDs into GO nanosheets through self-assembly, forming sandwiched hybrid heterojunctions. Interlinking QDs and GO nanosheets improves photocurrent generation (~5.8 μA cm-2) and enhances electron transfer by prolonging decay time (58.25 ms). The obtained higher rate constant value (k = 0.135 min-1) enables the degradation of 93% MB dye in 20 min. This work demonstrates a cost-effective strategy for constructing CdTe QDs/GO nanosheet hybrid heterojunctions with potential application in photocatalysis.

Summary: Inserting Gd ions into the crystalline lattice of ZnS quantum dots (QDs) enhanced their photo-catalytic activity. The influence of graphene oxide (GO) and graphitic carbon nitride (g-C3N4) on the photocatalytic activity of the ZnS QDs was also investigated. The results showed that the presence of Gd-doped ZnS QDs/g-C3N4 nanocomposite achieved the highest photocatalytic degradation efficiency and total organic carbon removal.

Summary: The objective of this study is to analyze the impact of shape and size alterations on the photoluminescence (PL) emission and photocatalytic activity of ZnO nanostructures. The study describes the controlled synthesis of ZnO nanoassemblies (NA) and nanocrystals (NC) using a soft chemical approach. The synthesized ZnO nanostructures were characterized using various techniques, including TEM, SEM, UV-vis, and PL measurement. The results show that the morphology of ZnO can be tuned by adjusting the molar ratio of DEG and water, which also affects the PL emission spectra. The controlled nanostructured growth demonstrates potential for sustainable photocatalytic activity under both UV and sunlight irradiation.

Summary: Carbon dots (CDs) have gained attention for their biocompatibility and tunable photoluminescence, but further analysis is needed before their use in clinical trials. A new type of carbon nitride dot (CND) has been found to selectively uptake cancer cells due to structural similarities with glutamine. The study investigates the effects of surface structural differences on the cellular uptake of CNDs and finds that the uptake mechanism is linked with ASCT2 and LAT1 transporters. CNDs show promise for selective cancer cell targeting by utilizing highly expressed transporters on cancer cells.

Summary: This study successfully synthesized multi-doped carbon dots (xCDs) with excellent fluorescence properties from microalga Chlorella pyrenoidosa using simple hydrothermal and microwave-assisted methods. The nonmetal doping in the nanomaterials was confirmed by XPS, while the existence of metals in the CDs was confirmed by ICP-OES and TEM, with Mg, Ca, K, and Na being the dominant doped metals. The synthesized xCDs were used for the modification of ZnO, and their photocatalytic properties were evaluated, showing promising potential for the degradation of carbamazepine.

Summary: In this study, Ni cocatalysts on a TiO2 composite photocatalyst with different graphene oxide (GO) contents were prepared using a hydrothermal method and characterized. It was found that the TiO2/GO/Ni nanosheet composites have a large specific surface area and can provide a large number of active sites for photocatalytic hydrogen production. GO can broaden the optical absorption range of TiO2 and absorb more visible light, stimulating the generation of more electron-hole pairs. Additionally, GO can collect electrons and promote the separation of electron-hole pairs. Ni, as a cocatalyst, can adsorb hydrogen ions and facilitate the migration of photogenerated electrons, thus ensuring high efficiency of the photocatalytic reaction.

Summary: In this study, CBS glass/Al2O3 composites were developed for LTCC applications based on a CaO-B2O3-SiO2 (CBS) glass system with a high boron content. The study revealed that the softening of glass and interfacial reaction between the glass and Al2O3 were the two most important factors affecting LTCC's densification process. Real-time shrinkage rate of LTCC during sintering was successfully simulated, and it was proven that the formation of the CaAl2(BO3)O phase played a significant role in reducing glass viscosity and promoting dense structure formation. The resulting LTCC composite exhibited excellent performance for high-frequency applications.

Summary: In this study, the disordering caused by swift heavy ion irradiation in two different compositions of pyrochlore structures was investigated. X-ray diffraction, Raman spectroscopy, and high-resolution transmission electron microscopy were used to analyze the samples before and after irradiation. It was found that both compositions underwent amorphization due to irradiation, with a slower rate observed in Nd1.8Zr2.2O7.1. The irradiation-induced modified track region in Nd1.8Zr2.2O7.1 consisted of defect-rich pyrochlore structure, anion-deficient fluorite structure, and amorphous domains.

Summary: Silicide ceramics, including tantalum disilicide (TaSi2), are known for their exceptional physical properties but are limited in practical applications due to their inherent brittleness at room temperature. In this study, we successfully improved the mechanical properties of TaSi2 ceramics and increased their electrical conductivity by modifying the preparation methods and sintering conditions. These findings provide valuable insights for future applications of TaSi2 and the design of advanced ceramic materials.

Summary: Microstructure design plays a crucial role in regulating the microwave dielectric properties of materials, however, the understanding of frequency temperature stability and related micromechanism remains limited. In this study, a combination of first-principles calculations and experimental observation was used to investigate the correlation among sintering behavior, crystal structure, bonding nature, and microwave dielectric properties of LnPO(4) (Ln = Eu, Pr) ceramics. The research findings systematically clarify the optimized effect and micromechanism of lanthanides on the dielectric properties of monazite ceramics, providing insights into the design and enhancement of microwave dielectric materials.

Summary: The study investigates the frictional and wear behaviors of carbon fiber-reinforced SiC ceramic matrix composites with different fiber orientations mating with ceramic balls. The results show that fiber orientation significantly affects the friction and wear properties of the composites. Pads with randomly arranged fibers demonstrate better friction stability and lower wear volume, potentially suitable for bearing material applications. The research also explores the factors influencing the formation of continuous tribo-film and identifies abrasive wear and oxidation wear as the dominant wear mechanisms for the friction pairs.

Summary: This study reveals the significant influence of resting time on the rheological properties of cement suspensions, which is closely related to non-absorbed polycarboxylate superplasticizers (PCEs) size variation. Adsorbed PCE during resting tends to bridge particles instead of dispersing them, leading to an increased yield stress.

Summary: This study investigates the effect of K/Na ratio on the phase structure, ferroelectric domains, and piezoelectric properties of potassium sodium niobate (KNN)-based ceramics. It reveals that high Na+ content leads to large ferroelectric domains, while high K+ content results in local polarity heterogeneity and distinct dielectric relaxational behavior. The balanced local polarity and stress heterogeneities contribute to improved piezoelectricity.

Summary: In this study, the micro-geometry morphology variation and microstructural transformation mechanism of muscovite crystals under electron beam irradiation were explored. The results revealed the instability of the muscovite lattice under irradiation, as well as the expansion and shrinkage of the lattice with increasing dose. The study also identified changes in chemical structure and other mechanisms involved. These findings are significant for the design of radiation-resistant silicate materials and the manufacturing of electronic components used in the aerospace industry.
