Abstract ：
As one of the most potent greenhouse gases, SF6 has a significant economic and environmental impact on the purification and recovery of exhaust gases from the semiconductor industry. The adsorption and separation performance of SF6 on a two-dimensional covalent organic framework TAT-COFs-1-AB with different functional groups (-SO3H, -Et, -NH2, -OMe, -OH, -H) was investigated by using grand canonical Monte Carlo (GCMC) simulations and density functional theory (DFT) calculations. The results show that the adsorption at low pressure depends on the interactions between the SF6 and COF frameworks, while at high pressure it is mainly affected by the porosity. The highest adsorption capacity of 8.44 mmol/g (298 K, 100 kPa) is exhibited by TAT-COF-1-AB-H, which has the highest porosity. Chemical functionalization was found to be effective in enhancing the SF6/N-2 selectivity. Among all the functionalized COFs, TAT-COF-1-AB-NH2, with the highest specific surface area and strong heat of adsorption, showed the highest selectivity. The simulation of self-diffusion also shows consistent results with the GCMC simulation. The findings highlight that the adsorption capacity is influenced by substituent and porosity, with SF6 showing a consistent preference for adsorption at hollow sites, as evidenced by binding energy and charge transfer analyses.

Abstract ：
CoSx materials with high catalytic activity are considered as promising HER electrocatalysts, but their inherent low electrical conductivity and easy loss of active sites have greatly limited their applications in OER electrocatalysis. Herein, we present a convenient method to synthesize Co-Cu hollow nanoprisms after wrapping and calcining with trithiocyanuric acid (C3H3N3S3) (denoted N-Co-Cu-S-x HNs). The results showed that Cu doping modified the charge density of Co center, leading to the enhancement of the intrinsic activity of the Co3S4 active center, meanwhile wrapping trithiocyanuric acid on the sur-faces and calcinating to form N-containing C skeleton as a flexible substrate to encapsulate the catalysts, which effectively protected the active sites inside the catalysts. Notably, the OER catalyst that was opti-mized by adjusting the metal ratio and controlling the trithiocyanuric acid incorporation exhibited a low overpotential of 306 mV under a current density of 10 mA cm-2 and showed a superior durability of more than 27 h. This work may provide some insights into the preparation of oxygen evolution reaction cata-lysts with excellent performance through doping transition metals and protecting the internal active sites strategies.(c) 2022 Elsevier Inc.

Abstract ：
Fabrics are considered to be promising alternatives to silicon wafers in wearable electronics, and the strain sensors developed based on them have attracted widespread attentions for their promising applications in health and motion monitoring, soft robotics and human-computer interaction, etc. However, existing fabric-based strain sensors (FSS) are usually prepared by complicated methods which greatly limit their practical applicability. Herein, high-performance FSSs were prepared by transferring graphene nanosheets (GNSs)/multi-walled carbon nanotubes (MWCNTs) mixing ink onto stretchable cloth adhesive tape via a simple one-step screen-printing method. The sensing range and sensitivity of the prepared FSSs were adjustable by designing different sensing patterns, and the FSS with a high GF (40) and a suitable strain range (30%) was used for detection of finger bending angles. The optimized FSS features excellent linearity (0.99), outstanding durability (>5000), superior breathability, good adhesion and ease of storage and use. Combined with morphological characterization and tensile tests, the sensing principle of the FSS was explained. Furthermore, a FSS-based sensing glove was inte-grated, and combined with LSTM deep learning model; it achieves a high accuracy (95%) of dynamic gesture recognition and can be used to control manipulator which demonstrates its promising applications in the field of smart wearable electronics and human-computer interaction.

Abstract ：
Constructing multi-component materials with dielectric-magnetic synergy effects has been a significant focus of recent works to enhance microwave absorption efficiency. Herein, a top-down exfoliation strategy for forming carboxylated g-C3N4 (CCN) was demonstrated to achieve rich interfaces and enhanced interface compatibility. The abundant defects and functional groups (-COOH, -OH, C-O, and CQO) of CCN enhanced the dipole polarization. Furthermore, MWCNTs and Fe3O4 were facilely decorated onto the surface of CCN by the general co-precipitation method to form CCN/C-Fe3O4 composite absorbers with multiple heterogeneous interfaces and attenuation mechanisms. Changing the content of CCN, CN/C-Fe3O4 exhibits excellent wave absorption and impedance matching charac-teristics with a minimum reflection loss value (RLmin) of -51.74 dB at only 1.9 mm (11.12 GHz), and the efficient absorption bandwidth can reach up to 4.28 GHz at 1.4 mm. This work reveals how CCN enhanced the synergistic balance between the dielectric-magnetic loss in composites. It also provides a new idea for the facile synthesis of novel multi-component composites for high-performance micro-wave absorption.

Abstract ：
The ability of electronic skin to detect and distinguish multiple tactile stimuli is important to properly mimic human skin. Although a few dual-parameter sensors have recently been designed to identify the most common tactile stimuli such as pressure and heat, it remains a difficult task to develop a dual-parameter sensor that is free from signal interference, easy to prepare, and signal readout, and requires no bias voltage. Here, we develop a simple but effective vertical stacking of sensing components strategy for high-performance dual-parameter sensing systems, in which multiwalled carbon nanotubes (MWCNTs)/textile and PEDOT:PSS/photopaper were designed as pressure- and thermal-sensitive components, and a layer of double-sided tape with a thickness of 200 mu m is sandwiched between two sensitive components for electrical and thermal isolation. The dual-parameter sensor exhibits good sensing performance in terms of sensitivity, response time, detection range, and stability for both pressure and temperature detection. More importantly, the tactile inputs of pressure and temperature can be distinguished without signal decoupling. The preparation of the dual-parameter sensor is simple and low cost, and its requirements for the readout device are as low as a single-chip microcomputer. This work provides a promising prototype for multiparameters e-skin, which has great potential for applications in robot applications, human-computer interaction, and intelligent wearable devices.

Abstract ：
Polyimide (PI) is widely used in the communication field benefited from its low dielectric properties and good electrical insulating properties, however, its low thermal conductivity simultaneously limits its application in electronic packaging. Delayed heat dissipation can exacerbate the thermal stress generated by device operation to damage electronic structures, thereby affecting work efficiency. As a result, it is necessary to improve the thermal conductivity of polyimide and maintain excellent dielectric performance. Here, we demonstrate the polyimide (BPDA-ODA) composites with ordered structure are prepared by filling commercial polyimides with aramid nanofibers connection nitrides greatly improve thermal conductivity and maintain the low dielectric loss. When the filling amount of SBN@CN is 30 wt%, the thermal conductivity increases to 1.162 W/mK, which is 8 times higher than that of pure PI (0.0147 W/mK). Moreover, thermal stability and mechanical properties are maintained, realizing that the dielectric constant is about 3.81 and the dielectric loss is as low as 0.0034 at 100 MHz, which endows a new insight for the application of polyimide in electronic packaging.

Abstract ：
Flexible strain sensors have made great progress and been applied tentatively in recent years. However, there are still many challenges and problems hindering their widespread application, including incompatible high sensitivity and wide detection range, poor durability, and time-consuming fabrication procedures. In this work, a dual-nozzle-assisted one-step strategy for the fabrication of integrated flexible strain sensors is proposed. During the fabrication, Ecoflex and its composite multiwalled carbon nanotube (MWCNT)/Ecoflex were extruded and thermally cured from the two nozzles, respectively. Taking advantage of the same base resin, the strain-sensitive and the insulating components in the fabricated flexible strain sensors are chemically bonded firmly and form an integrated device. The fabricated sensor exhibits good performance in terms of high gauge factor (GF = 165.3), good stability, low hysteresis, fast response time (60 ms), wide detection range (0%-300% strain), and ultralow detection limit (0.1% strain), showing promising applications in health monitoring and human-computer interaction.

Abstract ：
Covalent organic frameworks (COFs) have been remarkably evolved within the field of photocatalysis owing to their customizability and targeted functionalization. However, the exciton effect arising from the Coulomb interaction among electrons-holes cannot be disregarded. Exploring new approaches to regulate exciton dissociation on COFs to facilitate photocatalysis is significant. Within this work, localized defects were fabricated on the skeleton of the COFs by the one-step synthesis method of introducing monoaldehyde electron donors (pyrene, ferrocene, and triphenylamine). The formation of D-A configuration defects can directionally change the local electronic structure and charge distribution of COFs and induce enhanced dipole polarization, thus, promoting exciton dissociation and enhancing photocatalytic activity. Among them, the pyrene electron donor-constructed defective COF exhibited a 7.8-fold increase in the aqueous-phase oxygen-containing photopolymerization rate relative to the pristine COF, with a conversion rate of 80% within 30 min.

Abstract ：
Two-dimensional Ti3C2Tx (MXene) nanosheets with excellent electrical conductivity, a vast range of func-tional groups, and abundant surface defects reveal tremendous potential for electromagnetic wave (EMW) absorption. Nonetheless, the excessive conductivity of pure MXene may result in mismatches of electro-magnetic parameters and an inability to meet impedance matching requirements. Here, a facile self-as-sembly strategy was used to assemble MXene with ZnFe2O4 (ZFO) through polydopamine (PDA) to form ZFO@PDA@MXene (ZFPM) core/ shell/ shell composites, which solved this problem. By strong hydrogen bonding, MXene was successfully affixed to the interface of ZFO@PDA, forming a core/shell/shell structure, in which ZFO is the core, and PDA and MXene are the shells. Furthermore, the influence of MXene content on the EMW absorption performance for ZFPM composites was also investigated. Remarkably, the ZFPM composites containing 20 wt. % MXene exhibit strong EMW absorption, achieving an optimum reflection loss of -53.0 dB (99.9995 % absorption of EMWs) at a matched thickness of only 1.5 mm. The excellent EMW absorption performance is mainly attributed to the synergistic effect related to the core/shell/shell structure of the ZFPM composites and the magnetic dielectric loss. These results demonstrate that ZFPM composites are attractive candidates for EMW absorption applications and offer new ideas for the design of magnetic MXene-based absorbers.(c) 2023 Elsevier B.V.
