Photo-oxidative NO x removal often encountered with sluggish charge carrier separation kinetics and poor selectivity. Herein, Pd/ferroelectric Bi 4 Ti 3 O 12 nanoflakes (Pd/BTO NF) were constructed to investigate the photo-excited charge separation, O 2 activation and the generated reactive oxygen species (ROS) in dictating NO removal. Results showed that the depolarization field of ferroelectric BTO NF significantly promoted bulk charge separation, leading to boosted NO removal reaction kinetics (10 times higher) for Pd/BTO NF comparing with Pd/TiO 2 . Revealed by electronic paramagnetic resonance and radical scavenging tests, it is observed that the primary O 2 activation species differed among Pd, Ag and Pt supported BTO NF photocatalysts, which resulted in different selectivity. The underlying mechanism of NO photo-oxidative conversion pathway was studied by in situ diffuse reflectance infrared Fourier transform spectroscopy. This work illustrate that metal/ferroelectric interfaces can be tuned to obtain differing O 2 activation species, and notable selectivity changes in photocatalysis mediated environmental remediation reactions.

Similar to most air filtration strategies, fibrous filters have the trade-off between efficiency and air flow. An electrostatic-assisted electret filter may help improve filtration efficiency while maintaining air flow. In this work, we present a silk-nanofiber-modified polyethylene terephthalate (SNF@PET) fiber filter with an improved compression strength and modulus by 1.9 and 1.6 times respectively, at 2 wt % SNF content, increasing the structural stability of the filter to support a higher air flow. The filtration efficiencies of the SNF@PET fiber membrane for PM 0.3-0.5 and PM 0.5-1 are up to 99.7% and 99.6%, respectively, with a corresponding pressure drop of 3.3 Pa at 0.1 m s −1 air velocity. The SNF@PET fiber filter showed a slight decrease in filtration efficiency to 98.3% for PM 0.3-0.5 and a small increase of pressure drop to 3.7 Pa (from 3.3 Pa) after 400 h.

The rapid growth of lithium dendrites has seriously hindered the development and practical application of high-energy-density all-solid-state lithium metal batteries (ASSLMBs). Herein, a soft carbon (SC)-nano Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZTO) (with high ionic conductivity and diffusion coefficient) mixed ionic and electronic conducting interface layer is designed to promote the rapid migration of Li + at the interfacial layer, induce the uniform deposition of lithium metal on nanoscale (nano) LLZTO ion-conducting network inside the interface layer, effectively suppress the growth of lithium dendrites, and significantly improve the electrochemical performance of ASSLMBs. LiZrO 2 @LiCoO 2 (LZO@LCO)/Li 6 PS 5 Cl(LPSCl)-nano LLZTO/Li ASSLMB achieves high current density (12.5 mA cm −2 ), ultra-high areal capacity (15 mAh cm −2 , corresponding to LZO@LCO mass loadings of 111.11 mg cm −2 ), and ultra-long cycle life (20 000 cycles). Therefore, the introduction of SC-nano LLZTO mixed conducting interface layer can greatly improve the interfacial stability between solid-state electrolyte (SSE) and lithium metal anode to enable dendrite-free ASSLMBs.

Accurate monitoring of pulses is essential for assessing cardiovascular health. However, the specificity of the pulse wave depends on prestress applied to a wearable sensor. Here, we introduce a progressive contact area compensation strategy, which greatly extends the detection range of the sensor’s high-sensitivity region. It features a hierarchical flower surface structure and a gradient micro-/nanostructured hydrogel as the dielectric layer, compensating for the output decrease resulting from pressure hardening by gradually increasing the contact area between the contact–electrification interfaces. Consequently, the gradient micro-/nanostructured hydrogel, fabricated via electric field induction, enables the sensor’s high-sensitivity region to reach 1.1–52.2 kPa, a 5-fold improvement over that of comparable sensors. By integrating prestress adaptive units, signal processing modules, and a peak seeking algorithm, we develop a wireless wristband for continuous monitoring of cardiovascular status and blood pressure. Importantly, a preliminary 10 day blood pressure test on 22 volunteers showed an error margin of less than ±5 mm Hg, demonstrating its potential as a cardiovascular health product.

Lithium metal batteries specialize in energy density, while the immoderate dendrite growth and solid electrolyte interphase (SEI) proliferation have been impeding their practical application. The key is the regulation of Li + diffusion/nucleation behaviors toward a dense deposition. Herein, Li 9 Al 4 /Li 3 N energized mixed ionic/electronic conductive (MIEC) interfaces are pre-implanted in both the surface and bulk of the lithium metal anode. Such MIEC interfaces are activated from the in situ conversion and nano-alloying reactions between AlN and metallic Li and are uniformly dispersed via facile mechanical kneading. In vitro, MIEC interfaces participate in the formation of an inorganic-enriched SEI that balances ionic transport, electron blocking, and mechanical strength to guarantee homogeneous ion fluxes and structural integrity. In vivo, a unique nanorod-array architecture enables a released internal stress and rapid diffusion kinetics, affording a dense and large granular plating manner. As a result, the symmetric cell delivers a striking cumulative capacity of >120000 mAh cm −2 at 20 mA cm −2 @20 mAh cm −2 with a prolonged lifespan of over 6000 h. The improved machinability also enables a scalable fabrication of ultrathin foil to achieve a stable high-areal-capacity full cell for 320 cycles with enhanced energy density characteristics both gravimetrically and volumetrically.

Conducting polymer-based bioadhesive conductive interface (CP-BCI) are widely used in bioelectronics, strain sensors due to their ease of processing and fabrication, excellent electrical, and biocompatibility. However, CP-BCI is conventionally fabricated using techniques such as cast molding, screen printing, electrochemical patterning, and photolithography. These traditional methodologies often encounter challenges in achieving precise control and the generation of intricate patterns, thus limiting the widespread application and evolution of these materials. Direct ink writing has become an emerging research hotspot for processing CP-BCI due to its high degree of programmability, precision, and process stability. Herein, biointerface inks with enhanced electrical conductivity and high adhesion have been specifically developed for direct ink printing. The development of this novel ink involves the incorporation of PAM into the PVA matrix to promote composite cross-linking, coupled with the integration of PEDOT:PSS conductive nanofibers within the matrix, thereby yielding the PEDOT:PSS-PAM-PVA biointerface ink. The innovative ink showcases exceptional printability, high electrical conductivity (0.24 ± 0.053 S m −1 ), high adhesion (54 ± 2.7 kPa), and a well-balanced mechanical profile, featuring a maximum stress of 51 kPa and an elongation at break of 369%. This research introduces the novel direct writing ink, promoting advancements in the manufacturing of flexible electronics. Graphical abstract

Microwave ignition technology holds transformative potential in multi-point simultaneous uniform ignition for propulsion systems and energy conversion, attributable to its non-intrusive energy delivery and rapid response characteristics, yet it faces challenges in igniting metallic fuels like aluminum (Al) particles inert to microwaves. To address this critical problem of microwave energy coupling inefficiency in Al, interfacial layers of PF (C 8 H 12 ClNO 2 and CF 3 (CF 2 ) 7 CH 2 CH 2 SH) and APTES (C 9 H 23 NO 3 Si) were constructed to introduce chemical bonding and electrostatic adsorption on the Al surface, followed by inducing CUFO (CuFe 2 O 4 ) dielectric interface anchoring and forming Al@PF@CUFO and Al@APTES@CUFO. This construction of core/shell not only shortens the mass and heat transfer distance but also enhances the interfacial polarization, leading to a strong response to microwaves. Microwave ignition analysis indicates that Al@APTES@CUFO (23.41 ms) exhibits a shorter ignition delay time compared to Al@PF@CUFO (29.51 ms), which can be attributed to the superior bridging capability and rapid decomposition of APTES. APTES not only shortens mass and heat transfer pathways but also facilitates rapid microwave energy absorption by Al/CUFO under microwave irradiation, generating localized hotspots and accelerating the ignition reaction kinetics. Furthermore, Al@PF@CUFO reveals a 327% increase in combustion rate compared to Al@APTES@CUFO, attributed to the fluorination reaction induced by PF decomposition and carbon catalysis derived from the decomposition of PDA. These findings establish dielectric interface engineering as a paradigm-shifting approach to overcome microwave ignition barriers in metallic fuels, with implications for next-generation microwave-controlled solid propellants, pyrotechnics, explosives, etc.

The lithium (Li) metal battery reveals appealing merits in energy density but suffers from problems of dendrite growth and low coulombic efficiency before its applications. The ether electrolytes entitle Li metal batteries with more smooth Li stripping/deposition but narrow electrochemical stability in contrast to carbonate electrolyte. circumventing this contradictory, a lithium fluoride-nitride mixed ionic conducting interphase was embedded on lithium surface via formulated fluorine-rich carbonate and cyclophosphonitrile, which renders a dendrite-free plating/stripping over 2200 h and extend the electrochuemcial window of ether electrolyte to 4.5 V with the assistance of experiments and calculating simulations, ensuring LiCoO 2 to operate efficiently over 200 cycles with nearly no capacity decay.

SiO x /C composites are highly potential anode alternatives for next-generation lithium-ion batteries (LIBs) owing to their low cost and high theoretical capacity. However, the sluggish lithium-ion diffusion kinetics severely limit their practical capacity and rate performance. Herein, a high-capacity and high-rate anode based on commercial SiO x /C is facilely achieved by in situ constructing a Li + conductive interphase (LCI) to simultaneously boost the transport efficacy of Li + ions and buffer the volume expansion. The as-designed, LCI-protected SiO x /C anode delivers an exceptionally high capacity of 1420.9 mAh g −1 at 0.2 A g −1 , excellent rate performance (91.4% capacity retention from 0.2 A g −1 to 1 A g −1 ) and long cycling stability, substantially outstripping the pristine SiO x /C counterpart and most recently reported Si-based electrodes. More importantly, taking advantages of the fast and stable lithiation/delithiation processes, this electrode can also be adapted to further applications at large current densities (766.44 mAh g −1 at 5 A g −1 ) or high mass loadings (5.02 mAh cm −2 at 0.1 A g −1 , ∼3.5 mg cm −2 ). A full battery with satisfactory electrochemical performance is also demonstrated. The strategy of building ion conductive interphase to subtly tailor the transport behavior of Li + ions is anticipated to unlock the practical deployment of Si-based LIBs.

Rare circulating tumor cells (CTCs) are always harvested with large numbers of white blood cells (WBCs) by current CTC isolation techniques, which influences the accuracy of CTC-related gene and protein analysis. Therefore, it is very urgent to develop a method for efficient isolation of CTCs with high purity. In this work, we fabricated a reversibly assembled interface by layer-by-layer assembly of biotinylated poly-(L-lysine-graft-ethylene glycol) (PLL-g-PEG-biotin), streptavidin, and CTC-specific antibody on a three-dimensional conductive scaffold, and further embedded it into a customized microchip for CTC capture. The assembled multilayers increased the roughness of the scaffold, which improved the capture efficiency. Importantly, the PLL-g-PEG-biotin covalently coupled with CTCs could be detached from the scaffold by electrostatic repulsion, and the released CTCs could be recaptured on the conductive scaffold via electrostatic attraction while the WBCs were continuously drifted away. This reversible capture and release strategy significantly improved the purity of CTCs, and pure CTCs were obtained from cancer patients’ blood samples for gene mutation assay, which will be of great significance for assisting cancer diagnosis and treatment in a noninvasive way.

Conventional porous piezoresistive sensors suffer from lateral expansion due to a positive Poisson's ratio, causing conductive network fracture and unreliable signals. Existing structural solutions are limited by high costs and poor durability. This study introduces a dynamic conductive interface mechanism using liquid metal (LM) ink to bypass Poisson's ratio limitations. By coating eutectic gallium-indium (EGaIn) onto a hydrophilic porous thermoplastic polyurethane (TPU) scaffold, a strain-adaptive conductive layer is constructed, where LM droplets directionally flow to fill microcracks during deformation. This mechanism retains 98.73% of initial conductive pathways under 98% tensile strain, achieving ultra-high sensitivity (693.65 kPa −1 , 0.32-10.24 kPa). The LM-based sensor demonstrates intrinsic antibacterial properties and launderability. Integrated into an intelligent infant pillow with a 16-chanels sensor array, the system enables real-time cephalic pressure monitoring and edge-computed posture correction via a companion app. This work proposes a material-mechanics co-design strategy to overcome Poisson ratio constraints, advancing high-performance, scalable wearable biomedical devices.

Retinitis pigmentosa is the main cause of inherited human blindness and is associated with dysfunctional photoreceptors (PRs). Compared with traditional methods, optoelectronic stimulation can better preserve the structural integrity and genetic content of the retina. However, enhancing the spatiotemporal accuracy of stimulation is challenging. Quantum dot-doped ZnIn 2 S 4 microflowers (MF) are utilized to construct a biomimetic photoelectric interface with a 0D/3D heterostructure, aiming to restore the light response in PR-degenerative mice. The MF bio interface has dimensions similar to those of natural PRs and can be distributed within the curved spatial region of the retina, mimicking cellular dispersion. The soft 2D nano petals of the MF provide a large specific surface area for photoelectric activation and simulate the flexibility interfacing between cells. This bio interface can selectively restore the light responses of seven types of retina ganglion cells that encode brightness. The distribution of responsive cells forms a pattern similar to that of normal mice, which may reflect the generation of the initial “neural code” in the degenerative retina. Patch-clamp recordings indicate that the bio interface can induce spiking and postsynaptic currents at the single-neuron level. The results will shed light on the development of a potential bionic subretinal prosthetic toolkit for visual function restoration.
