Summary: This study investigated the effects of increased aluminum content on the glass-forming ability, microstructure, phase stability, mechanical properties, and deformation behaviors of Zr-rich Zr-Cu-Al alloys in bulk metallic glass composites (BMGCs). It was found that higher aluminum content improved the glass-forming ability of the alloys, leading to the fabrication of BMGCs with enhanced performance. The Zr-rich Zr-Cu-Al BMGCs exhibited a large fracture strain and high fracture strength under compression, with superior plastic deformation capabilities attributed to factors such as the formation of shear bands and interactions between crystals and shear bands.

Summary: The study investigates the impact of microstructure on hardness in phase-separated calcium aluminosilicate glasses. Hardness changes are governed by microstructural deformations during indentation. Phase separation leads to decreased hardness due to incongruent yielding of droplet and matrix phases. Microstructures with dilute, spherical droplets have minimal impact on hardness, whereas microstructures with concentrated, acicular droplets deform through droplet coalescence, resulting in improved hardness.

Summary: The addition of oxygen was found to enhance the plasticity of Zr60Cu25Al15 bulk metallic glass, but excessive oxygen deteriorated its plasticity, leading to partial crystallization. The improved plasticity was attributed to a heterogeneous Cu-rich amorphous phase, while the decrease in plasticity was caused by excessive oxygen leading to partial crystallization.

Summary: Until now, the focus of scientific research on recycling construction and demolition waste has been on the production of concrete, cements, and bricks. Existing methods involve the addition of binders, compaction, and possibly heat treatment, but lack a specific concrete recycling method. This study aims to develop new cement materials using 2.5% composite derived from construction and demolition waste powder for substitution in the construction industry. Characterization of the materials was done using X-ray diffraction (XRD), infrared (IR), and nuclear magnetic resonance (NMR) spectroscopy, revealing varied crystalline phases and reservoirs of water in the composite construction material. Micro-Vickers hardness measurements were taken to assess the local mechanical properties of the composite-cement mixture.

Summary: A series of instrumented nanoindentation tests were conducted on Zr52.5Cu18Ni14.5Al10Ti5 and Zr58.5Cu15.6Ni12.8Al10.3Nb2.8 as-cast and cold rolled samples to investigate the indentation size effect in three perpendicular planes. The results showed that the hardness, reduced modulus, and dynamic hardness decreased with increasing indentation depth in the rolling-width, normal-rolling, and normal-width planes. The size effect was analyzed using various models, indicating that dynamic mechanical softening and friction between the indenter and specimen were the underlying reasons for the observed indentation size effect.

Summary: The study demonstrates that laser surface melting can modify the hardness and shear banding behavior of bulk metallic glasses. Surface hardening and softening effects were observed post-LSM, with the introduction of compressive residual stress leading to increased surface hardening, and tensile residual stress resulting in surface softening. Differences in shear-banding mechanisms were detected near the surface, with reduced serrated flow and increased surface shear bands observed with compressive residual stress, and more pronounced serrated flows and deeper shear banding activity promoted with tensile residual stress following LSM.

Summary: A Zr55Cu30Al10Ni5 bulk metallic glass composite (BMGC) was fabricated using selective laser melting (SLM) with argon gas atomized powder. The microstructure and tensile deformation behavior of SLMed Zr55 BMGCs were studied, revealing a periodic microstructure with three different zones and a stepwise tensile fracture behavior. Nanoindentation tests showed that the nanocrystal + amorphous crystalline zone had lower hardness and elastic modulus, resulting in a significant stress drop after the failure of the hard amorphous layers. This study further confirmed the feasibility of SLM technology for developing high-performance BMGCs for industrial applications.

Summary: The effect of replacing P2O5 with different amounts of TiO2 on the crystallization, structure, and mechanical properties of an MgO-Al2O3-SiO2 system was investigated. The results showed that adding TiO2 favored the precipitation of fine grains and significantly increased the Vickers hardness, Young's modulus, and fracture toughness of the glasses. Introducing an appropriate amount of TiO2 can make a glass structure more compact, promote crystallization, and improve the mechanical properties of MgO-Al2O3-SiO2 glass-ceramics.

Summary: The effect of fluorine content on the crystallization, microstructure and mechanical properties of SiO2-Li2O glassceramics was investigated. Lithium disilicate (Li2Si2O5) is the main phase crystallizing during the heat treatment, while lithium metasilicate (Li2SiO3), petalite (LiAlSi4O10), and fluorapatite (Ca5(PO4)3F) appear in some samples as minor phases. The addition of fluorine increases the crystallinity and promotes the formation of Li2Si2O5 and Ca5(PO4)3F crystals, thereby regulating the microstructure and mechanical properties. Proper fluorine content significantly enhances mechanical properties.

Summary: In this study, a CO2 sensor capable of low-temperature operation was fabricated using an open-channel-type thin-film transistor structure with a polar surface of an oxide semiconductor. The sensor showed a sensitivity 2.9 times greater than that under an inert N2 atmosphere at an operating temperature of only 150 degrees C. The results suggest that TFTs fabricated with polar surfaces of oxide semiconductors are useful for gas-sensing applications.

Summary: A variety of hierarchical nanoporous silica aerogels were synthesized from well-dispersed silica sols, exhibiting diversified particle distributions and excellent thermal properties. The silica aerogels showed low thermal conductivity and high-temperature resilience. Surface modification and dilution of silica sols further improved the thermal resistance of the aerogels. The resilient skeleton structure developed from tiny particles effectively restricted heat dissipation and maintained the porous network at high temperatures.

Summary: In this study, a defective system of V-doped Fe2O3 with Pt as a cocatalyst was used for photoelectrochemical water oxidation. The defects in the VFPt-2.5 photoanode were characterized by XPS and EPR analyses. The SEM and TEM analyses revealed that the electrodeposited V-doped alpha-Fe2O3 had a nanosized morphology with an average diameter of 12 nm and a thickness of 300 nm. Under light irradiation, the VFPt-2.5 photoanode achieved a remarkable onset potential and photocurrent density. The stability test showed that Pt helped overcome the charge recombination caused by surface states.
