Summary: This paper explores an unexplored area in geopolymer and develops high-performance concrete. The optimal percentages of slag and activators, such as potassium and calcium hydroxide ratio, in metakaolin-based geopolymer are investigated. Different proportions of geopolymer concrete are cast using alkaline to binder ratios of 0.25, 0.35, and 0.45 and tested at 7, 28, and 90 days. The fresh, mechanical properties, probability, matrix, and smoothening plot for modulus of elasticity of geopolymer are investigated. The Ishikawa diagram discusses cause-and-effect factors of geopolymer concrete. Geopolymer exhibits medium workability and mechanical properties, and shows excellent results compared to traditional concrete at 30% slag usage and a 0.35 ratio of A/B. The optimum mix for geopolymer concrete with 30% GGBS achieves maximum strength.

Summary: In this study, a CsAlSi2O6-based glass-ceramic was prepared by sintering Cs-polluted soil and phosphate glass. Optimum glass addition was determined through extensive experiments and characterizations using XRD, DSC, SEM, and EDS. CsAlSi2O6 was formed at a significantly lower temperature (approximately 900 degrees C) compared to conventional sintering methods for Cs-pollucite. Raman spectroscopy and SEM studies confirmed the immobilization of Cs+ in the crystalline structure of CsAlSi2O6, with the crystals being encapsulated in the glass matrix. When the addition of phosphate glass was 10 wt%, the leaching rate was lowest (3.35 x 10-4 g m-2 d-1) and the bending strength was the highest (30 MPa). This study provides a potential alternative and useful data for the safe processing of radioactive waste at a relatively low temperature.

Summary: In this study, high porosity and high strength slag-based geopolymer syntactic foams were achieved through a combination of embedding hollow glass microspheres and direct foaming with H2O2 and a surfactant. The addition of hollow glass microspheres had a significant impact on the pore morphology, porosity, density, mechanical strength, and thermal conductivity of the foam material, leading to improved overall performance. The results indicated that the hollow glass microspheres were uniformly dispersed and well bonded with the geopolymer matrix.

Summary: Zirconia-based ceramics are popular in dental implantology due to their natural color and mechanical properties, but their biological inertness limits tissue integration. Doping with calcium and phosphorus in ZrO2-SiO2 nanocrystalline glass-ceramics enhances bioactivity and alters crystal phases during sintering, affecting strength and hardness. The resulting NCGCs exhibit plastic deformation behavior and sustained ion release, showing good biological activity and potential for sub-gingival applications.

Summary: Developing radiation-resistant materials and understanding structural damage caused by radiation are important goals for material scientists. In this study, ZrO2-SiO2 nanocrystalline glass-ceramics were irradiated with 1.4 MeV He ions at different fluences, and the resulting structural integrity and damage were investigated. The results showed that microstrain from the irradiation induced a phase transformation in the ZrO2 crystals, while the addition of yttrium stabilized the tetragonal-ZrO2 phase. Raman spectroscopy indicated changes in the electronic structure of the amorphous SiO2 component, and microscopy revealed the formation of microcracks and lattice defects as the main structural damage.

Summary: By recycling waste clays, non-foamed and foamed geopolymers were successfully prepared. Geopolymers made from calcined Feeder's waste-clay exhibited the best compressive strength, while geopolymers made from a mixture of 50% calcined Feeder's waste-clay and 50% calcined Cyclone's waste-clay also showed good compressive strength. Additionally, foamed geopolymer with suitable compressive strength was prepared from calcined Cyclone's waste-clay, showing higher apparent porosity and lower bulk density than non-foamed geopolymers.

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: 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.
