The proliferation of high-power electronics and 5G technology has created an increasing demand for high-performance electromagnetic interference (EMI) shielding materials that are durable, breathable, and comfortable for wearable applications. Although silver-coated textiles offer excellent shielding, their limited durability and susceptibility to corrosion hinder their practical use. This study develops a flexible, breathable, and corrosion-resistant electromagnetic interference (EMI) shielding spacer fabric using a multi-step coating strategy. The fabric features a conductive network formed by PDA-assisted electroless silver plating, followed by a thiol self-assembled layer (HDT) and finally encapsulated with a thermoplastic polyurethane (TPU) coating. The optimized composite fabric demonstrates an EMI shielding effectiveness (EMI SE) of up to 57.74 dB in the X-band, with excellent air permeability (2436.1 mm s −1 ), superior corrosion resistance (only 7.8% resistance change after immersion in Na 2 S solution), and mechanical durability (negligible resistance changes after 3000 compression cycles). Combined with its superhydrophobicity (contact angle >140°), this fabric offers a promising solution for wearable electronics and personal protective applications. The proliferation of high-power electronics and 5G technology has created an increasing demand for high-performance electromagnetic interference (EMI) shielding materials that are durable, breathable, and comfortable for wearable applications.

Despite the practical advantages of conducting 5-hydroxymethylfurfural (HMF) electrooxidation to 2,5-furandicarboxylic acid (FDCA) in acidic media, such as facilitated product separation and improved reactant stability over alkaline environments, the lack of efficient electrocatalysts has hindered the development of efficient acidic processes. Herein, we reveal that HMF oxidation reaction (HMFOR) shares key oxygen-containing intermediates ([O], e.g., *OH and *OOH) with oxygen evolution reaction. By incorporating Ir into manganese oxide (MnOx), the kinetic constraints of acidic HMFOR were successfully broken. Specifically, in the designed Ir-MnOx, the presence of Ir sites not only accelerates the generation of [O] species to provide abundant oxidative active species but also modulates the electronic structure of Mn sites to activate their reactivity and enhance HMF adsorption. Synergistic cooperation between Ir and Mn sites endows Ir-MnOx with a record-high HMFOR current density (56.2 mA cm−2@1.40 VRHE), along with high FDCA selectivity (94%) and yield (92%) in an acidic electrolyte (pH 1.89). This work provides mechanistic insights and a design strategy for efficient HMFOR electrocatalysts in acidic environments.

Cardiovascular diseases remain a leading cause of death worldwide, with acute myocardial infarction (AMI) accounting for a significant proportion of fatalities. The rapid and accurate detection of cardiac troponin I (cTnI) is critical for early diagnosis of AMI. We report an innovative, highly sensitive, solidly mounted resonator (SMR) biosensor based on a c-axis-tilted scandium-doped aluminum nitride (Sc0.1Al0.9N) film for label-free cTnI detection. The SMR device, fabricated by magnetron sputtering and incorporating an acoustic Bragg reflector, is designed to operate in the shear acoustic mode. The sensor demonstrates a quality factor of 2030 and an effective electromechanical coupling coefficient of 2.6%. Functionalized with a self-assembled monolayer and monoclonal antibodies, the sensor achieves a detection limit of 3 pg/mL for cTnI in serum, with a rapid response time of 100 s and high selectivity against common interferents. The device also exhibits significant potential for integration with CMOS electronics, supporting the development of miniaturized, point-of-care (POC) diagnostic systems for cardiovascular diseases.

Beta-actin (ACTB), a highly conserved cytoskeletal protein, is frequently dysregulated in early-stage malignancies, making its sensitive and specific detection crucial for cancer screening. Here, we develop a reflective fiber-optic SPR biosensor functionalized with copper–glycine engineered WS₂ nanosheets for label-free ACTB detection. The Cu–glycine modification not only enables WS₂ surface amination for efficient antibody conjugation, but also introduces Cu²⁺-mediated near-infrared absorption to amplify the plasmonic resonance response. Combined with the intrinsically large surface area and high refractive index sensitivity of WS₂, this synergistic design markedly enhances both molecular binding and signal transduction. The resulting WS₂-NH₂-based sensor achieves a refractive index sensitivity of 1467.5 nm/RIU, representing a 1.67-fold enhancement over unmodified fiber probes. For ACTB detection, it delivers an ultralow detection limit down to 9.766 pM, a broadened linear range of 2.4–120 pM (5×expansion), and a biosensing sensitivity of 84.477 nm/nM (1.4× improvement). Furthermore, at 1 ng/mL, a rapid response time of 20 min is achieved, demonstrating applicability for trace-level biomarker screening. Integrating high sensitivity, broad dynamic range, amplified spectral response, and strong anti-interference capability, this plasmonic WS₂-NH₂-modified fiber platform enables highly selective, label-free ACTB quantification. These findings highlight its strong potential for early cancer diagnosis, biomarker monitoring, and precision medical applications.

Traditionally, adsorption is believed to take place only in the ground state, but here we report an excitation-driven adsorption mode. Composites of metallophthalocyanines and carbonaceous substrates are prepared, among which the potassium-phthalocyanine (KPc)/reduced graphene oxide (RG) composite shows the most typical behavior. Femtosecond transient absorption spectroscopy and first-principles simulations reveal that under ultraviolet (UV) irradiation, the excited electrons in the composite transfer efficiently from KPc to RG, leaving long-lived excited holes on KPc that enable selective adsorption of CO molecules. In the dark, the composite shows negligible CO adsorption (0.06 mmol g⁻ 1 ), whereas its CO uptake increases to 1.20 mmol g⁻ 1 upon UV light, with a UV-modulated adsorption capacity ratio of up to 95%. This adsorption mode is also applicable to other metallophthalocyanine/carbonaceous composites. This work presents a potential strategy for photoexcitation utilization and the development of energy-efficient chemical separation technologies.

Exogenous nutrient bags are essential for the artificial cultivation ofMorchella sextelata, but the effects of different formulations on yield, nutritional quality, and the soil microecological environment remain unclear. In this study, nine exogenous nutrient bag formulations and one conventional treatment (CK) were evaluated duringM. sextelatacultivation. Fruiting time, fresh and dry yields, and nutritional quality indicators were measured, and principal component analysis combined with membership function analysis was used for comprehensive evaluation. Soil physicochemical properties were determined for all treatments, and A7, A3, and CK were selected to represent the best-performing, worst-performing, and conventional treatments, respectively, for soil microbial community analysis. Different formulations significantly affected agronomic and nutritional traits (p< 0.01). A6 showed the shortest fruiting time and the highest fresh and dry yields, whereas A7 had the highest polysaccharide content and ranked first in the comprehensive evaluation. The D values of A7, A6, and CK were 0.789, 0.777, and 0.653, respectively. Soil nutrient analysis showed that morel cultivation markedly altered soil nutrient structure, especially available nutrients and phosphorus-related indicators. Microbial analysis showed that A7 had the highest bacterial richness among the three sequenced treatments and stronger colonization byM. sextelata. Its bacterial and fungal communities were also more closely associated with soil organic carbon. Overall, A6 was more suitable for yield-oriented production, whereas A7 showed the best comprehensive performance when yield, nutritional quality, and soil ecological characteristics were considered together.

Ferroptosis and sonodynamic therapy (SDT) have both been recognized as powerful weapons in cancer treatment, especially in non-small-cell lung carcinoma (NSCLC) recently. However, the lack of effective sono-sensitizer and ferroptosis regulator limited their usage. In order to overcome the limitation, a novel nanoplatform of DTX-CS/ART/PFCA@RGD (cRCAPD) was fabricated based on SDT and ferroptosis. Nanoparticles, under the action of c(RGDfk) cyclic peptides and their skeleton chondroitin sulfate (CS), could specifically target αvβ3 and CD44 receptors, respectively, thereby targeting tumor sites. Meanwhile, the peroxy-bridge structure of ART disrupted the intracellular iron homeostasis while generating highly toxic reactive oxygen species (ROS) under the SDT. Docetaxel (DTX) in nanoparticles led to the excellent apoptosis of A549 cells. Oxygen carried by PFCA alleviated the tumor hypoxic microenvironment, downregulated HIF-1α, and provided substrates for SDT. Further, the nanoparticles showed a strong immunogenic cell death (ICD) effect, modulating the number of T cells and dendritic cells in tumor-bearing mice. In summary, the proposed therapeutic strategy based on SDT and ferroptosis holds promising potential for synergistic treatment of lung cancer in future clinical applications.

Liquid
lubricants are crucial for advanced bearing equipment, as
they help mitigate key tribological issues including friction and
wear, thereby reducing the risk of failure and extending service life.
Herein, a low-viscosity, high-affinity deep eutectic solvent (TB-C 12 OH DES) was synthesized by blending tetrabutylammonium chloride
with 1-dodecanol using a simple heating-stirring method, and it was
used as a high-performance lubricant for steel substrates. The as-synthesized
TB-C 12 OH DES showed favorable physicochemical properties.
Reciprocating friction tests demonstrated that TB-C 12 OH
DES achieved low friction coefficients (0.081–0.090) and ultralow
wear rates (3.02–4.75 × 10 –9 mm 3 N –1 m –1 ) under high-load
conditions (2.16–3.12 GPa). These results are attributed to
the formation of stable adsorption film and tribofilms consisting
of carbonaceous compounds and iron oxides at the tribointerface through
adsorption and tribochemical reactions. This straightforward preparation
strategy not only meets specific lubricant requirements but also paves
the way for the development of eco-friendly DES-based lubricants with
high lubricating performance to address friction and wear challenges
under complex operating conditions.

The electrochemical CO 2 reduction reaction (CO 2 RR) is a proton−electron coupled transfer process in which active hydrogen (*H) plays a pivotal role in determining the reaction pathways, particularly for methane (CH 4 ), a representative deep hydrogenation product. However, how *H generation and migration govern CH 4 formation remains elusive, motivating mechanistic elucidation to enable rational regulation of reverse hydrogen spillover. Herein, we develop Cu-doped ZrO 2 catalysts and reveal that tuning the crystallinity of the ZrO 2 support enables control over the reverse hydrogen spillover process. Specifically, amorphous ZrO 2 functions as an efficient “hydrogen pump” by promoting *H generation and lowering the migration barrier toward adjacent Cu sites, thereby strengthening the reverse hydrogen spillover effect. This effect establishes an optimal *H coverage for deep hydrogenation of CO 2 , thereby reducing the energy barriers for key intermediates along the CH 4 formation pathway. Consequently, the Cu-doped amorphous ZrO 2 catalyst delivers a CH 4 Faradaic efficiency of 69.3% with a partial current density of −372.8 mA cm −2 , significantly surpassing that of its crystalline analogue. This work highlights that engineering the crystallinity of metal oxide supports provides an effective strategy to regulate reverse hydrogen spillover in electrocatalysis, offering valuable insights into controlling catalytic activity and product selectivity.

The recovery of lithium from spent lithium-ion battery (LIB) leachates remained challenging because strong acidity and complex ion compositions compromised the stability and selectivity of conventional nanofiltration (NF) membranes. In this work, an acid-resistant membrane was synthesized via covalent grafting of histidine (HIS) onto a polyamide (PA) layer (PA-HIS) through secondary interfacial polymerization (IP). In acidic media, imidazole protonation generated positively charged imidazolium sites that repelled H + , suppressing acid-catalyzed amide hydrolysis. Beyond this protective effect, HIS moieties enhanced surface hydration and water flux. The imidazole groups further promoted multivalent cation coordination and improved ion selectivity. This modified membrane maintained 98.9% Na 2 SO 4 rejection after 28 days at pH = 1, demonstrating excellent chemical durability. When electro-nanofiltration (ENF) based on the PA-HIS membrane was carried out for separating simulated acidic LIB leachates, the rejection of Ni 2+ , Co 2+ , and Mn 2+ of over 99.8% and Li + rejection of –35% were achieved to yield a separation factor S Li/(Ni,Co,Mn) of around 600. Continuous operational stability was further confirmed and exhibited exceptionally high ion selectivity ( S Li/(Ni,Co,Mn) > 400). These results demonstrated that HIS grafting enhanced acid durability, and electric field regulated ion discrimination, facilitating Li recovery from acidic LIB leachates.

Beta
zeolite is widely used for the deep conversion of
heavy oils
(e.g., hydrocracking) owing to its strong acidity and suitable pore
architecture; however, its purely microporous channels impose severe
diffusion limitations for bulky molecules, restricting industrial
performance. Herein, a predominantly crystalline shaped Beta zeolite
catalyst with a tunable hierarchical pore network is developed by
coupling TEAOH-induced secondary crystallization with a surfactant-assisted
soft-templating strategy. This synergistic approach enables in situ
binder-to-zeolite transformation while generating intracrystalline
mesopores, yielding shaped bodies with high mechanical strength, tunable
acidity, and interconnected micro-mesoporous pathways. A dual-template
strategy is further developed, enabling fine-tuning of the mesoporosity.
The superiority of pore engineering of shaped zeolite is further demonstrated
in tetralin hydrocracking as a model reaction. The optimized 70B Si -0.6T-C catalyst achieves significantly enhanced performance,
with a tetralin conversion of 94.9% and a high BTX yield of 28.5%
at 380 ° C and a high weight hourly space velocity of 8.0 h –1 , markedly outperforming the untreated counterpart.
The improved catalytic behavior is attributed to the synergistic effects
of binder-to-zeolite transformation, restoration of Brønsted
acidity, and enhanced mass transport enabled by intracrystalline mesopores.
This work provides a general and scalable strategy for constructing
industrially relevant hierarchical zeolite catalysts, offering improved
activity and selectivity for the hydroconversion of bulky molecules.

One-step Laser-induced graphene fabrication is achieved via chitosan modified with trimethyl phosphate and glycerol. • The modified film achieves a high carbon residue of 35.3% and low sheet resistance of 23.7 Ω/sq. • The fabricated LIG serves as a multifunctional platform for temperature sensors, supercapacitors, and TENGs. • TMP-improved flame retardancy enables one-step laser graphitization while preserving flexibility and biodegradability. Chitosan (CS), one of the most abundant natural polymers on Earth, is a potential biodegradable precursor for Laser-induced graphene (LIG) fabrication. Nevertheless, pure CS and its derivatives often face challenges regarding insufficient mechanical properties or poor conductivity during one-step laser graphitization. To address these issues, this work proposes a novel modification strategy utilizing trimethyl phosphate (TMP) as a flame retardant and glycerol as a plasticizer for CS composite films (CTM). The incorporation of TMP significantly enhanced the thermal stability of the CS films, resulting in a high carbon residue yield of 35.3% at 750 °C. Through the optimization of laser scribing parameters, the resulting CTM-LIG flexible films achieved a sheet resistance as low as 23.7 Ω/sq. Leveraging the CTM-LIG flexible films fabricated via one-step CO₂ laser scribing, we successfully constructed various proof-of-concept green electronic devices, including a flexible temperature sensor with a rapid response time of 460 ms, a supercapacitor (SC) with high cyclic stability (99.1% capacity retention after 5000 cycles), and a triboelectric nanogenerator delivering a maximum power density of 277 mW/m 2 . Collectively, these results and proof-of-concept demonstrations establish CTM-LIG as a versatile multifunctional platform for sustainable transient electronics via a simple and scalable one-step laser fabrication strategy.
