This paper reports a novel manufacturing process of preparing the Three-Dimensional Multiaxial Braided Composites(3DMBCs) and the effects of various defects generated in the manufacturing process on the compressive mechanical properties of 3DMBCs through the experimental and numerical methods. The five-step fabrication process of the 3D multiaxial braided preform was firstly introduced in detail. Then, the influences of various defects such as voids, waviness, and fiber breakage defects on the compressive properties of 3DMBCs were discussed. It is found that the fiber breakage defect and waviness defects were the two primary factors on the decrease of compressive properties of 3DMBCs. However, void defects in the resin and interface had little effect on the composites. When the fiber breakage defect content was 25% and the waviness was 7°, the composite compressive modulus decreased by 51%. The progressive damage process and failure mechanism of the composite under 90° compressive loading confirmed the validity of the numerical model by comparing with the experiments.

Influence of the topological Lifshitz transition on the superconductivity of the high-pressure electride Li4Pd

引用

Physical Review B 2025年第10期111卷 L100505-L100505页

作者： Zhiyao Guan Tian Cui Da Li State Key Lab of Superhard Materials and Key Laboratory of Material Simulation Methods and Software of Ministry of Education College of Physics Jilin University Changchun 130012 People's Republic of China School of Physical Science and Technology Ningbo University Ningbo 315211 People's Republic of China

High-pressure electride (HPE) superconductors often maintain structural symmetry over a wide pressure range, whereas their interstitial anion electrons (IAEs) undergo significant changes in topology and energy levels, potentially resulting in topological Lifshitz transitions in their Fermi surfaces. These Lifshitz transitions can play critical roles in influencing superconducting properties. However, their impact on the superconductivity of HPEs remains largely unexplored. To address this gap, we investigate a novel HPE, Li4Pd, which features distinct Fermi surfaces, including a hole ellipsoid and a warped electron rectangular cylinder. This combination satisfies the conditions for a Kohn anomaly, suggesting that Li4Pd may be a potential HPE superconductor. Our theoretical calculations reveal that under high pressures, the Fermi surface of Li4Pd undergoes a Lifshitz transition that affects the momentum distribution of electrons on the Fermi surface, leading to changes in the energy provided by phonons for forming Cooper pairs. Moreover, this transition modifies the phonon frequencies involved in electron-phonon coupling. The superconducting transition temperature of Li4Pd is calculated to be 34.5 K at 250 GPa, which is comparable to that of Li6P (39.3 K at 270 GPa). Our findings indicate that the formation of closed Fermi surfaces with extended spatial scales is a general feature that could be leveraged to design new classes of high-temperature superconductors among HPEs.

In order to enhance the reliability and accuracy of the results by the transient plane source (TPS) method for measuring the thermal conductivity of wood. This paper investigates setting parameters and measurement methods to improve measurement accuracy. Criteria are proposed to determine the optimal parameters such as power output, heating time, and time window. The results show that the total to character time, temperature increase of the probe, mean deviation, and temperature drift graph are valid indicators for evaluating the detection reliability of the TPS method. The optimal parameters for measuring the thermal conductivity of wood using the TPS method are: power output of 0.05 or 0.1 W, heating time of 120 seconds, and time window covering 60% to 80% of the heating time. The thermal conductivity measured with the TPS method is higher than that measured by the steady-state method in all grain angle directions. © 2024, The Authors. All rights reserved.

Ag-doped Cu nanoboxes supported by rGO for ultra-stable Zn anodes in aqueous Zn-ion battery

Advanced aqueous zinc-ion batteries have been greatly limited application caused by uncontrollable dendrite formation, hydrogen evolution and zinc metal corrosion, which can lead to quick failure of the battery and low Coulombic efficiency. Three-dimensional (3D) porous host strategy is available to limit zinc dendrite growth and electrode interfacial side reactions. Herein, an ingenious local levelling and macro stereo strategy is rationally designed as a Zn plating/stripping scaffold. The flexible 3D carbon cloth as the structural and conductive framework is coated by Ag-Cu-reduced graphene oxide (Ag-Cu-rGO) and Ketjen black. Benefiting from the uniformly dispersed zincophilic Ag on the surface of Cu nanoboxes, the anode suppresses hydrogen evolution side reactions and reduces local current density via more nucleation sites. In addition, rGO homogenizes both the ion flux and electric field at the electrode surface, resulting from high conductivity and large specific surface area of rGO. As a result, the fabricated Zn//Ag-Cu-rGO asymmetric cells exhibit stable voltage profiles for plating and striping 250 cycles, maintain nearly 100% Coulombic efficiency at 2 mA·cm^(−2) and 1 mAh·cm^(−2) as well as behave an extremely small nucleation overpotential of 34 mV and Ag-Cu-rGO@Zn symmetric cell presents highly uniform electric field with a superior lifespan over 2500 h at 1 mA·cm^(−2) and 1 mAh·cm^(−2), respectively. Meanwhile, this efficient Ag-Cu-rGO@Zn anode also enables a substantially stable Ag-Cu-rGO@Zn//V2O_(3) full cell over 2000 cycles. The work opens a new avenue of 3D host for durable and dendrite-free flexible aqueous zinc-ion batteries anode.
