Zr-based bulk metallic glasses (BMGs) exhibit significant potential for a wide range of applications, owing to their exceptional glass-forming ability (GFA) and mechanical properties. However, while the addition of beryllium (Be) or rare-earth elements can improve the GFA of Zr-based BMGs, it often raises safety concerns or compromises their mechanical performance, limiting their industrial applicability. Therefore, the development of Be-Ni-free Zr-based BMGs with both superior GFA and mechanical properties remains a considerable challenge. In this study, we successfully prepared an industrially applicable Be-Ni-free (Zr61Ti2Cu25Al12)100-xYx BMG via Y-doping, demonstrating high GFA and excellent mechanical properties. We found that trace Y-doping significantly enhances both GFA and plasticity, with Y0.1 achieving a critical diameter of 13 mm and Y0.3 exhibiting a remarkable compressive strain of 18.91 %. Additionally, using the (Zr61Ti2Cu25Al12)100-xYx BMGs, we successfully fabricated industrial BMGs plates with thicknesses of 2 mm via high-vacuum, high-pressure die casting (HV-HPDC). The industrial BMGs plates of Y0.3 also exhibited the unexceptionable flexural strength of the 2.46 GPa. This work provides a novel approach for the exploration of BMGs for industrial applications and represents a significant step toward their commercialization and structural use. © 2025 Elsevier B.V.

Rare Metals 2006年第4期25卷 382-388页

作者： CHENG Bei YU Xiaoxiao YU Jiaguo ZHAO Xiujian State Key Laboratory of Advanced Technology for Material Synthesis and Processing Wuhan University of Technology Wuhan 430070 China

BaCO3 whiskers exhibiting different morphologies were fabricated by a simple precipitation reaction of barium ch/oride with sodium carbonate in the absence and presence of poly-（styrene-alt-maleic acid）（PSMA） as a crystal growth modifier at room temperature. The as-prepared products were characterized by scanning electron microscopy （SEM）, transmission electron microscopy （TEM）, and X-ray diffraction （XRD）. The influences of experimental parameters on the size and morphology of BaCO3 whiskers were investigated and discussed. It was found that the as-prepared BaCO3 whiskers are single crystals with diameter ranging from 100 to 300 run, and grow along the crystallographic a-axis or [100] direction. BaCO3 whiskers with different morphologies, such as branching and dendritic structure, can be obtained depending on the experimental conditions. With increasing PSMA concentration, the diameter of BaCO3 whiskers decreases.

Relaxor-antiferroelectrics (relaxor-AFEs), known for their double polarization–electric field (P-E) hysteresis loops and relaxor characteristics, exhibit outstanding energy storage performance compared to other dielectric materials. However, the origins of their antiferroelectric-like behavior and relaxor features remain unclear due to their complex local structure. In this study, we designed relaxor-AFEs with a high degree of relaxor component and stable antiferroelectric behavior. The recoverable energy density (Wrec) of up to 4.6J/cm3 and energy efficiency of ∼ 79 % were achieved in a 0.76NaNbO3-0.16Na0.5Bi0.5TiO3-0.08CaTiO3 ceramic, demonstrating excellent thermal and frequency stability. The multiphase local polarization configuration was confirmed by atomic-resolution annular dark-field scanning transmission electron microscopy (ADF STEM). Additionally, integrated differential phase contrast (iDPC) images revealed an enhanced antiferrodistortion (AFD) induced by incorporating component with low tolerance factor, contributing to stable antiferroelectric behavior. The relationship between chemical heterogeneity, polarization configuration and energy storage performance was systematically established. This work provides insights into the structure origin and underlying mechanisms for relaxor-AFE performance, with potential implications to guide the development of advanced energy-storage dielectric materials. © 2025 Elsevier B.V.

To obtain homogenous layered oxide Li（Co1/3Ni1/3Mn1/3）O2 as a lithium insertion positive electrode material, the sol-gel process using citric acid as a chelating agent was applied. The material Li（Co1/3Ni1/3Mn1/3）O2 was synthesized at different calcination temperatures. XRD experiment indicated that the layered Li（Co1/3Ni1/3Mn1/3）O2 material could be synthesized at a lower temperature of 800℃, and the oxidation state of Co, Ni, and Mn in the cathode confirmed by XPS were ＋3, ＋2, and ＋4, respectively. SEM observations showed that the synthesized material could form homogenous particle morphology with the particle size of about 200 nm. In spite of different calcination temperatures, the charge-discharge curves of all the samples for the initial cycle were similar, and the cathode synthesized at 900℃ showed a small irreversible capacity loss of 11.24% and a high discharge capacity of 212.2 mAh·g^-1 in the voltage range of 2.9-4.6 V.

Ltd. Hangzhou311100 China

This essay aims to study how different contents of the transition element Zr modify the Ni-Cr filler alloy. The goals are to reduce the alloy's thermal corrosion on diamond, improve brazed-diamond quality, and systematically explore post-brazing diamond wear properties. The results show that adding Zr optimizes the microstructure of the Ni-Cr filler alloy and enhances its hardness. Meanwhile, Zr reacts with Ni to form two new intermetallic compounds, Ni₁₀Zr₇ and Ni₇Zr₂, which consume partial Ni atoms and reduce the catalytic corrosion of diamond. The addition of Zr also effectively improves the retention strength of diamond and inhibits thermal damage to diamond during brazing. At the brazed interface, not only Cr₃C₂ and Cr₇C₃ but also a small amount of ZrC are generated. In addition, the mechanical experiments showed that adding Zr improved the hydrostatic strength of brazed diamond, increased the removal amount of ground specimens, and reduced the degree of diamond breakage when the addition amount was 1.0 wt% Zr, the hydrostatic strength of the diamond reached 2871.6 MPa, the removal amount of the ground specimen reached 44.2 mg, and the brazed specimen possessed the best comprehensive mechanical properties. © 2025 Elsevier B.V.

Two-dimensional (2D) phase-transition memristors have demonstrated transformative potential for neuromorphic computing, yet challenges like high power consumption, limited endurance, and crystal damage from external ion intercalation persist. Here, we introduce a novel 2D phase-transition memristor leveraging a paradigm-shifting mechanism by exploiting the ultrafast intrinsic Cu+ ion migration within Cu2S. This approach eliminates the need for external ion insertion, significantly reducing crystal damage and enabling exceptional cycling stability with over 400 DC cycles and 500 pulse cycles. The susceptible monoclinic-tetragonal phase-transition induced by intrinsic Cu+ migration achieves an unprecedented SET power consumption of 1 μW at 100 mV, significantly lower in currently reported phase-transition memristors. To further demonstrate the potential of intrinsic ion migration-induced (IIM) memristor, we simulated an IIM memristor crossbar array for image preprocessing in gesture recognition with a high SSIM value of 0.94, showcasing its potential for scalable neuromorphic hardware. This work establishes a new paradigm in low-power, high-performance phase-transition memristors, advancing their practical application in next-generation computing. © 2025 Science China Press

This study aimed to curtail the secondary damage caused by traditional dressings by cross-linking TEMPO-mediated oxidized sodium alginate (TOSA) with silk fibroin (SF) through the EDC system and preparing the scaffolds through freeze-drying and anhydrous ethanol immersion. The good adsorption, mechanical properties, high porosity, and good in vitro and in vivo biocompatibility of the scaffold can improve the healing efficiency of the wound. Additionally, sodium alginate was oxidized by the TEMPO system to lower its molecular weight and hence increase the degradation rate of the scaffold. Consequently, the scaffold demonstrated a rapid degradation rate (42.26 % degradation in 7 days) in the in vitro enzyme solution. The scaffold will not induce secondary damage to the wound and does not require removal. Furthermore, the oxidation degree of sodium alginate was regulated by the TEMPO system, supporting the preparation of degradation-adapted skin tissue engineering scaffolds. © 2025 Elsevier Ltd

Ferroelectric random access memory (FeRAM) plays a vital role in information storage due to its unique advantages, driving the demand for high-capacity and high-density solutions. In this paper, a series of PbZr1-xTixO3 (x = 6 %, 8 %, 10 %, 12 %, 14 %) films were prepared using sol-gel and spin-coating methods. As the Ti content increases, the enhancement effect of the ferroelectric order is reflected structurally in XRD and Raman spectra, and electrically in the dielectric and ferroelectric properties. Notably, for x = 12 %, the P-E hysteresis loop exhibits slightly pinched and double-like, and the peaks of the I-V curve are split on both the positive and negative field sides. This ferroelectric behavior is caused by an underlying triple-well free-energy landscape, which is the basis of tristate ferroelectric memory. The measurement results show that the "±1" and "0" states of PbZr0.88Ti0.12O3 film under electric field cycling exhibit excellent programmability. It also achieves promising data retention up to 1000s and endurance up to 107 cycles. This investigation not only verifies the feasibility of applying tristate ferroelectric memory to PZT-based films but also provides a facile method for fabricating tristate ferroelectric memory devices. © 2025 Elsevier Ltd and Techna Group S.r.l.

TiB2 powders coated with BN were prepared by Hybridization System making use of dry impact blending method to achieve powder surface modification. Parameters of coating were analyzed and the most appropriate condition was summarized. Scan electron microscope of JSM-5610LV and transmission electron microscope of H-600STEM/EDS were used to observe the microstructure of coated powders. Results show that treatment time, rotation speed, granularity ratio of TiB2 to BN, pretreatment of materials etc influence the coating results evidently. Mixing raw materials and coating with BN under the appropriate condition can get round TiB2/BN composite powder with smooth surface and compact coating layer.
