The construction of lunar stations for research and living requires high-performance building materials that can adapt the harsh lunar environment. One of feasible building materials is fiber-reinforced composites, for which the composition of glass fibers can be designed like lunar soils, i.e., terrestrial basalt and in turn, the "lunar glass" can be drawn into fibers. Because of a wide variation of TiO2 in lunar soils, our study focused on a series investigation on the effect of TiO2 (0.55 wt% - 6.14 wt%) on fiber spinnability and strength of the simulated "lunar glass and glass fibers". The baseline glass composition was derived from a simulated TiO2-lean lunar soil and other glasses were made at different TiO2 doping levels. The addition of TiO2 was found to reduce the melt thermal stability, there appears a TiO2 threshold (6.14 wt%), at which fibers cannot be drawn without breakage because of melt devitrification. The fiber tensile strength exhibits a nonlinear characteristic with an apparent maximum at 1.52 wt% TiO2. FTIR and Raman spectroscopic studies were carried out to investigate the glass network structure responses to TiO2 modifications and show TiO2 functions as a network modifier, depolymerizing the silicate network. Statistical structure (FTIR & Raman based)–property modeling was attempted to further elucidate the effect of TiO2-induced structure change on Tg and fiber tensile strength. Good agreements were found between the model predictions and the measured values. © 2023, The Authors. All rights reserved.

Wearable/portable devices are essential for the automation, intelligence and digitization of next-generation electronic products. However, it is still challenging to obtain a kind of flexible, transparent and lightweight power source for these. Here, both a dual-electrode poly-(dimethylsiloxane)/copper nanowires (PDMS/Cu NWs) based TENG and a single-electrode mode TENG based on half-embedded Cu NWs electrode and PDMS/Cu NWs negative friction layer was fabricated by cost-effective and feasible methods. Respectively, these as-obtained TENGs show good flexibilities and transparency. Meanwhile, the two kinds of TENG exhibit high output voltages and power densities of 120 V and 2.0 W/m 2 , 45 V and 0.135 W/m 2 , respectively. The enhancements are ascribed to the increase of capacitance and electron flow in the friction layers caused by doping Cu NWs. The advantages of the PDMS/Cu NWs based TENG include the ease of fabrication, good biocompatibility, flexibility and transparency, empowering it as a promising sustainable method for obtaining daily environmental energy as a self-powered source to drive wearable/portable electronic devices. © 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.

A physically-based thermo-viscoelastic constitutive model of phantom and entangled networks in amorphous shape memory polymers

引用

Mechanics of Materials 2025年 208卷

作者： Jianwei Deng Haibao Lu Yong Qing Fu Science and Technology on Advanced Composites in Special Environments Laboratory Harbin Institute of Technology Harbin 150080 China Xi'an International Scientific and Technological Cooperation Base for Advanced Biosensing and Precision Instrumentation Xi'an Jiaotong University Xi'an 710049 China School of Materials Science and Engineering Xi’an University of Technology Xi’an Shanxi 710048 China

Amorphous shape memory polymers (SMPs) are one of the most prominent smart and intelligent materials, whose constitutive models play important roles for their engineering designs and applications. Over the past decades, various thermo-viscoelastic constitutive models have been developed to simulate their shape memory behaviors, but these models are mostly phenomenological and often unable to explain the underlying mechanisms of their viscoelasticity and shape memory effects. Herein we propose a physically-based thermo-viscoelastic constitutive model to describe SMPs’ shape memory behaviors. We propose that the SMPs are composed of both hard and soft phase chains. The hard phase chains form a backbone network showing strong elastic responses, which can be modeled with a phantom network model. Whereas the soft phase chains form transient networks and entangled networks exhibiting viscoelastic behaviors, which can be explained using contour length relaxation and disentanglement relaxation phenomena. Time-temperature superposition principle is then incorporated to capture critical time-temperature dependence of the viscoelasticity and thermally induced shape memory effect. The proposed model has been implemented numerically and validated using shape memory experimental results at different recovery temperatures and heating rates, during the shape memory processes of amorphous SMPs. This work presents a good understanding of the viscoelasticity and shape memory effects of amorphous SMPs at the polymer chain level, and also provides an effective constitutive model for practical applications.

Cellulose nanofiber-based thermal interface materials demonstrate significant potential for application in miniaturized electronic devices with high-power. However, they face a significant limitation: low through-plane thermal conductivity (TC). In this study, we designed a novel dual-channel structure through leveraging volumetric exclusion effect of a thermoplastic polyurethane (TPU) template during vacuum filtration process. A primary channel was constructed based on a cherimoya-like core-shell structure (TPU@Al2O3), wherein TPU microspheres served as the core and spherical Al2O3 constituted the shell. Meanwhile, functional boron nitride (f-BN) was assembled into interstitial spaces of these biomimetic core-shell particles to form an auxiliary channel. These films with 16 vol% Al2O3 and 20 vol% f-BN can achieve a through-plane TC of 2.07 W/mK, representing a thermal conductivity enhancement (TCE) ratio of 508 %. The synergistic efficiency between Al2O3 and f-BN attains an exceptional value (159.8 %), which is resulted from the high matching degree (0.413) between their phonon density of states. Thermal conduction behavior of composite films with distinct structures was simulated to investigate the mechanism of the TCE through the transient-state finite element method via COMSOL. Meanwhile, the films with the dual-channel structure exhibit excellent performance of thermal management as thermal interface materials (TIMs), effectively reducing the operating temperature of a central processing unit (CPU) with a powder dissipation of 253 W to 35 °C, which is lower than 22 °C compared to pure CNF. The innovative design of dual-channel structures in films pave the way for broad applications of CNF in the thermal management of electronic devices. © 2025

Manganese-based hexacyanoferrate has garnered unprecedented attention for sodium-ion batteries due to their high theoretical capacity. However, the structural strain associated with Jahn-Teller distortion incurs fast capacity decline and poor rate capability. Effectively reconciling the trade-off between low-strain and rapid-kinetics in manganese-based hexacyanoferrate cathode poses a considerable challenge. Herein, an elegant strategy based on the stress engineering of heterointerface on nickle-doped manganese hexacyanoferrate@nickle hexacyanoferrate core@shell cathode is proposed to balance the volume strain and charge transfer kinetics during charge/discharge process. As evidenced by the operando X-ray diffraction experiments, differential electrochemical mass spectrometry, and theoretical calculations, the interfacial stress can be regulated by precisely tailoring the shell thickness to stabilize the built-in electric field, which ensures the good structural stability and fast charge diffusion kinetics. Consequently, the as-developed cathode delivers a reversible capacity of 81.0 mAh g−1, excellent cycling stability (81.9 % of capacity retention after 800 cycles), and superior rate performance (55.1 mAh g−1 at 10 C). Our work heralds a promising strategy of heterointerface strain engineering for exploring advanced MnHCFs cathode materials toward high-performance sodium storage. © 2025 Elsevier Inc.

One stone, two birds: Polyaniline film with the difunctional characteristic of fast-response multi-color electrochromic and excellent super-capacitive behaviors

Applied Surface science 2025年 707卷

Electrochromic energy storage (EES) of polyaniline (PANI) materials holds great potential for improving energy efficiency in sustainable development. However, improving and balancing the electrochromic property and capacitance performance of the PANI material remains a significant challenge. Here, the galvanostatic (GS) electropolymerization technique is proposed to prepare a PANI film with outstanding electrochromic and excellent energy-storage properties. The evolutions of the structure mechanism of PANI films are revealed during its two-step growth process. The PANI film displays multicolor transitions across transparent, yellow, green, blue, and purple under applied potentials. Compared to those reported in the PANI-EES literature, the research achieves a greater variety of color variations. Furthermore, a large optical contrast of 50 % at 630 nm and an extremely fast electrical response time of 0.1 s are observed. The PANI film also exhibits a remarkably high specific capacitance of 509 F g−1 and maintains high contrast. The fabricated EES device provides preliminary validation that the PANI film can simultaneously achieve pseudocapacitive behavior and electrochromic behavior in one device. This work achieves PANI films with multi-functional characteristics for various emerging multicolor electronics, supercapacitors, and EES optoelectronic devices. © 2025
