Oil-water mixtures, especially the surfactant-stabilized oil-in-water emulsions with high stability, are causing great difficulties for effective separation. In this work, a modification strategy was proposed to prepare functionalized stainless steel felt for emulsion separation by coating the felt with 3-triethoxysilylpropylamine, followed by the introduction of silica nanoparticles using a sulfur-based three-component coupling reaction. To satisfy the pore size requirement for effective emulsion separation, the developed felt was processed using a compression molding. With special wettability, optimized pore size, and electrostatic demulsification mechanism, the positive charged felt delivered outstanding separation capabilities for oil-in-water emulsions stabilized by various surfactants. Specifically, the flux and COD removal efficiency for the anionic-stabilized emulsion were up to 3911 L/m2/h and 95.3%, while for cationic-stabilized emulsions, which were 1305 L/m2/h and 93.1%. The results indicated that surface charges played an important role in governing the separation performance of the felt, and the electrostatic attraction demulsification demonstrated better separation capabilities than that from the electrostatic repulsion process. © 2024, The Authors.

Influence of pre-existing interfacial damage on the ballistic behavior of ceramic composite armor systems: An experimental and numerical analysis

引用

Thin-Walled Structures 2025年 215卷

作者： Shibao Wu Chaocan Cai Guanjie Wang Xiaojun Wei Zhonghai Xu Qingyu Peng National Key Laboratory of Science and Technology on Advanced Composites in Special Environments Harbin Institute of Technology Harbin 150080 China Suzhou Research Institute of HIT Harbin Institute of Technology Suzhou 215104 China

In recent years, Ceramic composite Armor Systems (CCAS) have gained extensive applications in protective configurations of various armored weapon platforms due to their exceptional ballistic behavior. Nevertheless, the integration of functional modules into cohesive interfaces for enhancing CCAS intelligence presents a technical paradox: such modifications inevitably induce pre-existing interfacial debonding/delamination defects that may adversely affect ballistic behavior. Using a simplified Al 2 O 3 /Carbon Fiber (CF)/Aramid Fiber (AF) composite armor configuration as a representative example, this work systematically examines through combined Ballistic Limit Test (BLT) and Finite Element Analysis (FEA) how pre-existing damage parameters (including location, area and quantity) at both Al 2 O 3 -CF and CF-AF interfaces influence critical ballistic behavior responses, especially the residual velocity, back face deformation, damage circumstance and its extension patterns, etc. The results of the FEA are validated with the experimental results. The key findings reveal that under equivalent damage areas with single pre-existing damage, interfacial debonding at the Al 2 O 3 -CF interface demonstrates more pronounced ballistic behavior degradation compared to the CF-AF interface defects. This detrimental effect exhibits amplification beyond critical damage tolerance thresholds. Under dual pre-existing damage conditions, the detrimental effects on the ballistic behavior of the CCAS exhibit significant dependence on damage area combination characteristics.

MXene (Ti3C2Tx) is a new 2D material with both hydrophilicity and high electrical conductivity, and it has shown promise in smart electronic devices. Reported herein is a homogeneous MXene film actuator with high electrical conductivity triggered by moisture gradients. The actuator is highly sensitive to moisture and undergoes deformation, with the maximum bending angle as high as 155° at a relative humidity difference of 65 %. Several analysis methods show that the humidity drive and large deformation of the MXene film occur in situ by asymmetric expansion of the bilayer structure. The combination of deformation and electrical conductivity makes this film applicable to flexible excavators, electrical switches, and other fields, applications that are difficult to achieve directly by using other 2D materials. More importantly, this work further expands the new application range of MXene materials and provides new opportunities for building the next generation of high-conductivity smart actuators. © 2020 Wiley-VCH Verlag GmbH & Co.

Self-powered triboelectric nanogenerators (TENG) have shown great potential in the field of electronic skin (E-skin). However, TENG is vulnerable to damage by frequent mechanical impacts during operation. In this work, a self-healable (≤ 2 h), super-stretchable (> 760%) and shape-adaptive TENG was designed as an E-skin to harvest energy and monitor human motion. The triboelectric layer is self-healing double-crosslinked polydimethylsiloxane (PDMS) prepared by adjusting the ratio of imine bonds to hydrogen bonds (H-bonds). The electrode layer is self-healable conductive composite prepared via the formation of H-bonds between MXene and lightly cross-linked PDMS. This TENG can be perfectly attached to the uneven human skin surface due to shape adaptability and can maintain original triboelectric performance after repeated damage. Also, our TENG can switch freely between single sensor and sensor arrays due to high self-healing efficiency, suggesting promising applications in E-skin and wearable device. © 2022, The Authors.

The infectivity of SARS-CoV-2 depends on the binding affinity of the receptor-binding domain (RBD) of the spike protein with the angiotensin converting enzyme 2 (ACE2) receptor. The calculated RBD-ACE2 binding energies indicate that the difference in transmission efficiency of SARS-CoV-2 variants cannot be fully explained by electrostatic interactions, hydrogen-bond interactions, van der Waals interactions, internal energy, and nonpolar solvation energies. Here, we demonstrate that low-entropy regions of hydration shells around proteins drive hydrophobic attraction between shape-matched low-entropy regions of the hydration shells, which essentially coordinates protein-protein binding in rotational-configurational space of mutual orientations and determines the binding affinity. An innovative method was used to identify the low-entropy regions of the hydration shells of the RBDs of multiple SARS-CoV-2 variants and the ACE2. We observed integral low-entropy regions of hydration shells covering the binding sites of the RBDs and matching in shape to the low-entropy region of hydration shell at the binding site of the ACE2. The RBD-ACE2 binding is thus found to be guided by hydrophobic collapse between the shape-matched low-entropy regions of the hydration shells. A measure of the low-entropy of the hydration shells can be obtained by counting the number of hydrophilic groups expressing hydrophilicity within the binding sites. The low-entropy level of hydration shells at the binding site of a spike protein is found to be an important indicator of the contagiousness of the coronavirus. © 2022, CC BY.

Zr-based ultra-high temperature ceramics (UHTCs) are widely used as the key parts of aircrafts in thermal protection systems. However, such materials usually have a high sintering temperature and it is difficult to obtain complex parts using traditional manufacturing methods. This study reports on the success preparation of complex Zr-based UHTCs by a light-curing 3D printing process. The results indicate that the smaller the precursor particle size, the higher is the viscosity of the slurry used for printing. Slurries with a better curing performance can be prepared by mixing various active diluents and photoinitiators with an optimized certain proportion. The stability of the slurry can be improved by adding coupling agents and dispersants. The main components of the 3D printed green parts are ZrC, SiC and pyrolytic carbon at 1800 °C, yielding a high compressive strength (102 ± 2 MPa) and elastic modulus (65 ± 1 GPa). ZrC/SiC composite ceramic parts with low open porosity (3.99 %) were obtained by 3D printing after heat treatment, which provides an effective way to design complex UHTC parts for extreme environment applications. © 2025
