Intelligent wearables integrated by multifunctional sensing mechanism of biomechanics and biomolecules are crucial for personalized health management. However, there is a modal discrepancy between biomechanics and biomolecule sensing. Hence, a preparation strategy for biomimetic fibers of polyvinylidene fluoride (PVDF)@ sliver (Ag) is developed originally, and multimodal sensing for biomechanics and biomolecules is bridged by textile carrier. A nanofiber membrane of PVDF is prepared by one-step electrospinning method. Then the compact and homogeneous Ag nanoparticles (NPs) are in-situ grown on the high-curvature fibers of PVDF by reducing the reduction potential of silver ion. Thus, a fiber membrane of PVDF@Ag with piezoelectric response and localized surface plasmon resonance (LSPR) effect is produced, which is adaptive for wearable sensing both muscle movements and secreta molecules. Moreover, in order to obtain the ordered arrangement of high-density hotspots of LSPR along the three-dimensional direction, the twisting of PVDF@Ag fiber imitating the microstructure of the antennae of butterfly is designed, which has more stable output signal of surface-enhanced Raman scattering (SERS) than untwisted fiber, and could resist the signal decay caused by tensile deformation during the wearable sensing. Based on their "fingerprint" spectra of SERS, noninvasive extraction and detection for secretion signals at sweat and respiration are realized. And a reasonable relationship between the output spectrum of secretions and health information is also investigated. In sum, the fiber of PVDF@Ag bridges the barrier between the biomechanics and biomolecule. And, the integrated PVDF@Ag by polyester fabric also show excellent moisture absorption, air permeability and antibacterial ability. Such a multimodal sensing mechanism implanted by deep-learning-assisted algorithm means to be of importance during the wearable healthcare management applications. © 2024, The Authors. All rights

The use of nanomaterials to enhance bioprocessing for the removal of pharmaceuticals and personal care products (PPCPs) has received increasing attention. However, the interactions between nanomaterials and microbial communities are unclear. This study reveals the potential and mechanism of synthesized octahedral molecular sieve and activated carbon fiber (OMS-2@ACF) composites in enhancing the aerobic microbial capacity of sequencing batch reactor (SBR) for the treatment of carbamazepine. In an SBR, a series of doses (0-1.0 g/L) of OMS-2@ACF were introduced to investigate their impact on the treatment of carbamazepine by activated sludge. OMS-2@ACF demonstrated an enhancing effect on the carbamazepine removal performance of the SBR. Furthermore, the SBR reactor with the addition of 1.0 g/L of OMS-2@ACF exhibited the most effective removal of carbamazepine. Illumina high-throughput sequencing revealed that OMS-2@ACF material altered the composition of the microbial community in the SBR, identifying the Comamonas as the key genus contributing most significantly to the community response. Analysis indicated that the presence of OMS-2@ACF material increased metabolic pathways associated with contaminants degradation, resulting in improved treatment performance of the SBR. © 2023, The Authors.

Epoxy structural adhesive has good mechanical properties, especially high adhesion, low shrinkage rate, and high stability, widely used in steel plate reinforcement, crack repair, bridge splicing, and concrete bonding, etc. However, due to the high cross-linking density and high internal stress after curing, its shortcomings, such as brittleness, the poor performance of fatigue resistance and heat resistance, limit its application in special track engineering. In this work, two kinds of epoxy structural adhesives (EPA-1, EPA-2) with low viscosity and room temperature curing were synthesized by selecting different bisphenol A epoxy resin and active diluent as component A and modified amine curing agent as component B. The results showed that EPA-1 and EPA-2 presented significant toughness compared with the classic construction adhesive (AralditeXH160). The yield strengths of EPA-1 and EPA-2 were 4.88 MPa and 13.13 MPa, and the shear strengths were 11.93 MPa and 13.08 MPa, respectively, showing good adhesive properties. In addition, the viscosities of EPA-1 and EPA-2 were 127 mPa·s and 308 mPa·s, respectively, and their decomposition temperatures were all above ~280 ℃, which indicated that the self-made epoxy structural adhesives could be used for the repair of cracks in the vibration subway tunnel. © 2021 Institute of Physics Publishing.

Conductive hydrogels, regarded as an optimal flexible electronic material. Nevertheless, the pressing concern of simultaneously achieving excellent mechanical and conductive properties in hydrogels necessitates immediate attention. In the study, the exceptional mechanical properties of hydrogels were achieved by employing a strategy that involves constructing a three-dimensional nano-structure network, inspired by the highly ordered structure observed in dragonfly wings. The conductivity and anti-freezing of the hydrogel were enhanced through the construction of a conductive mechanism, achieved by combining inorganic salts with metal nano-particles. The conductive hydrogel exhibits outstanding properties, including anti-freezing, ultra-stretchable (6000%), extraordinary high toughness (8.32 MJ m-3), low Young's modulus (3.8 kPa), impressive conductivity (16.2 S m-1), a transparency level of up to 91.2% and excellent sensitivity in strain sensor. The regulation of the hydrogel matrix's topology and the formation of bionic nano-structures synergistically establish the ultra-stretching and energy dissipation mechanism of the hydrogel. And the high conductivity of the hydrogel is achieved by constructing a synergistic conduction pathway, which incorporates metal nano-particles and inorganic salts. Under the stretching-induced effect of hydrogel, the conductive structure facilitates a more efficient pathway for conduction, thereby enhancing its conductivity and sensing sensitivity under significant strains. Subsequently, this hydrogel was successfully applied to wearable sensor technology, demonstrating surprisingly remarkably prompt non-delayed sensing performance even at low-temperatures. It approach presents abundant opportunities for expanding the application scope of hydrogels in flexible electronics. © 2024, The Authors. All rights reserved.

Solar interfacial desalination is a potential pathway for freshwater using solar energy and brine. Many recent advances have been extensively studied to high-efficiency solar steam yield, however, the decrease of evaporation performance resulted from salt accumulation at absorbers inevitably hinder their development, especially in high-salinity brine (>10%). Here, we propose a Janus and superhydrophilic design for efficient and stable solar interfacial desalination in high-salinity brine. The Janus structure of the absorber, which has an upper layer of very light-absorbing (>95%) carbon fiber powder and a bottom layer of insulated aramid fiber powder, allows for efficient thermal management to prevent heat loss and promote efficient water evaporation. Furthermore, the impact of carboxylate cellulose ensures that the absorber with an ultra-high-water content. Therefore, the Janus and superhydrophilic design can realize an evaporation rate as high as 1.25 kg m −2 h −1 with a salinity of 15 wt% brine under 1-sun illumination and achieve salt resistance in outdoor conditions for a long time. Therefore, this technique simply integrates outdated fiber powder with the current solar interfacial evaporators and establishes a new paradigm for very effective and reliable high-salinity brine treatment. © 2022, The Authors.

In the framework of the model of a spatially nonuniform Bose-Einstein condensate with helicoidal spin-orbit (SO) coupling, we find abnormal Peregrine solitons (PSs) on top of flat and periodic backgrounds, with ultrahigh amplitudes. We explore the roles of the SO coupling strength and helicity pitch in the creation of these anomalously tall PSs and find that their amplitude, normalized to the background height, attains indefinitely large values. The investigation of the modulation instability (MI) in the same system demonstrates that these PSs exist in a range of relatively weak MI, maintaining the feasibility of their experimental observation.

The construction of covalent adaptable networks (CANs) without the need for post-modification, complex monomer synthesis routes, or expensive materials is highly desirable for the practical application of dynamic covalent chemistry. In the present study, the commercially available acrylate monomer, diacetone acrylamide (DAAM), was initially polymerized using a traditional radical polymerization method. Subsequently, it was cross-linked with amine agents under hot-processing conditions to form aliphatic imine-based CANs. The resulting materials exhibited glass transition temperatures (Tg) in the range of 95 to 107°C, good thermal stability, mechanical and thermomechanical properties. All samples were amenable to mechanical recycling. Post-recycling, both the tensile strength and Young's Modulus exhibited a slight deterioration, retaining approximately 80% of their original properties. The results from gel content analysis and structural characterization of both pristine and recycled samples indicate that the observed reduction in mechanical properties and Tg (approximately 70°C) can be attributed to a decrease in the degree of cross-linking and the release of aliphatic ketone groups. Furthermore, all samples demonstrated degradability under acidic conditions, attributable to their aliphatic imine structure. By using this facile approach to prepare acrylate-based imine CANs, we establish an important framework for polymer materials that are both reprocessable and biodegradable. © 2024, The Authors.

Electronic textiles with functions of temperature monitoring and human motion detection have attracted considerable interest, especially those which can be operated under extreme conditions such as high temperature. However, the restricted working conditions and poor stretchability have limited the practical application of most reported electronic textiles. Herein, we report a facile and scalable strategy to fabricate flame-resistant sensing yarn with a core–sheath structure for temperature monitoring and strain sensor applications via a large-scale spinning technique. The hierarchical yarn comprises a spandex filament as the core, carbon nanotube (CNT)-coated aramid fibers as the middle layer, and aramid fibers as the sheath. The obtained spandex/CNT@Aramid/Aramid (SCAA) yarn exhibited stretchability up to 160% with excellent thermal resistance, outstanding thermal insulation performance, and temperature monitoring ability within a wide-range of 50–400 °C. Additionally, SCAA-based textiles showed excellent strain sensing performance in a wide operating temperature range (0–300 °C). Based on the above, a SCAA-based textiles which can transmit high-temperature alarms through active (stretching) and passive (thermosensation) modes was designed, enabling temperature monitoring presenting at extremely high temperatures. We believe this work will contribute to the development of practical sensing e-textiles towards applications in harsh environment. © 2022, The Authors. All rights reserved.
