Flexible wearable pressure sensors have attracted tremendous interest for applications in human health monitoring, electronic skin, artificial intelligence and so on. However, it is still a critical challenge for pressure sensors to simultaneously achieve high sensitivity and wide sensing range while performing well in response time, stability, reliability and wearing comfortability. Here, conductive MXene/cotton fabric was fabricated using the simple dip-coating technique and then sandwiched between polydimethylsiloxane film and an interdigitated electrode for flexible wearable piezoresistive pressure sensor. The abundant hydroxyl groups of cotton fabric and functional groups of MXene were beneficial for the good adhesion of conductive MXene nanosheets onto the entangled fiber networks, constructing effective conductive network. Taking advantage of the excellent flexibility and three-dimensional porous structure of cotton fabric and the special sandwich architecture of the sensor, the MXene/cotton fabric (MCF) based pressure sensor exhibited high sensitivity (5.30 kPa −1 in the pressure range of 0–1.30 kPa), broad sensing range (0–160 kPa), rapid response/recovery time (50 ms/20 ms), excellent stability and long-term durability. Moreover, the MCF based pressure sensor can be employed to detect and distinguish various human health signals, including finger motion, early stage Parkinson’s static tremor and wrist pulse. Importantly, E-skin was also designed based on the MCF based pressure sensor for the recognition of different tactile stimuli, exhibiting promising potential in next generation wearable electronics.

Gastrodia elata Bl. ( GE ), a widely utilized edible and functional material, exhibits notable quality variations due to distinct growing conditions across different geographical origins, making reliable methods for origin authentication and quality evaluation essential. This study integrated machine vision, flash GC e-nose and HPLC to analyze GE samples from Anhui (AH), Shaanxi (SN), and Yunnan (YN) provinces in China. Results showed comparable color characteristics among geographical origins, but distinct textural differences: SN samples displayed more complex textures with higher surface roughness, YN samples showed richer textural details but less distinct edges and lower periodicity, while AH samples exhibited smoother surfaces. Eleven flavor compounds were identified as potential flavor markers. Although no significant differences were found in the total content of six marker components, three linear machine learning models (PLS, SVM, and LDA) established based on multidimensional features achieved 100% classification accuracy in training and prediction sets, providing a reliable approach for GE geographical origin traceability.

A new photoelectrochemical (PEC) system by means of adding sodium sulfite (Na 2 SO 3 ) was developed to treat sewage. The PEC system simultaneously promoted pharmaceuticals and personal care products (PPCPs) degradation, H 2 evolution and E. coli disinfection using an optimized, visible–light driven BiVO 4 photoanode. The PEC reactions were first carried out in 1.5 mM Na 2 SO 3 electrolyte. 92.3% of 2 ppm benzophenone-3 (BZP) was degraded, and 115.36 μmol of H 2 was produced in 90 min at 1.0 V vs. Ag/AgCl, which was a significant improvement over cases where the electrolyte was either Na 2 SO 4 or NaCl. The sulfite ions were first activated by holes and then converted into sulfate radicals, which played a dominant role in the degradation of BZP. As the holes were caught by the sulfite, charge separation was also enhanced, increasing H 2 evolution. The PEC reactions were also used to treat real sewage, in which case an 82% improvement in the rate constant of BZP degradation, 60% increase of H 2 evolution, and 0.78 log enhancement of E. coli disinfection were achieved by adding 1.5 mM Na 2 SO 3. The system was also feasible to degrade various PPCPs, and showed excellent reusability and stability, proving its great potential in sewage treatment.

The low water solubility and poor thermal stability of Vitamin E (VE) limit its application in food processing. This study investigated the effects of the synergistic combination of electron beam irradiation (EBI) at doses of 0, 5, and 10 KGy and ultra-high pressure (UHP) at 100, 300, and 500 MPa on the preparation of potato starch-VE complexes. EBI pretreatment significantly reduced the degree of branching and enhanced complexation, antioxidant activity, and resistant starch (RS) content in a dose-dependent manner, whereas increasing UHP pressure progressively diminished these attributes. The combination of 10 KGy EBI with 100 MPa UHP yielded the highest RS content (67.24%) and DPPH scavenging activity (85.02%). XRD analysis indicated no V-type crystalline formation, suggesting weak but sustained complexation. The parameter-dependent effects of EBI and UHP offers a promising approach to produce starch-VE complexes with improved antioxidant capacity and digestion resistance, benefiting functional food development for diabetics.

A machine learning-driven strategy for optimal feature selection is proposed. • W1W and W1C sensors serve as key variables for aroma type classification. • 131 volatile compounds were identified in Liupao tea. • 14 aroma type differentiating compounds were identified. • 4 key variables yielded 100% accurate aroma recognition models. This study aimed to differentiate between the stale-aroma and betelnut-aroma types of Liupao tea by analyzing their volatile profiles. An integrated methodology was employed, combining electronic nose (E-nose) technology with headspace gas chromatography-ion mobility spectrometry (HS-GC-IMS). The E-nose data effectively differentiated between the two aroma types in both dry leaves and tea infusions. HS-GC-IMS enabled identification of 131 volatile compounds. Key discriminative features were selected through machine learning by integrating the variable importance in projection (VIP) from orthogonal partial least squares discriminant analysis (OPLS-DA) with Shapley additive explanations (SHAP) values from extreme gradient boosting (XGBoost). This process identified two critical E-nose sensor channels and two key volatile compounds. Utilizing these four optimal variables, three classification models were developed: principal component analysis-linear discriminant analysis (PCA-LDA), partial least squares discriminant analysis (PLS-DA), and support vector machine (SVM). All models demonstrated a perfect classification accuracy of 100% on both the training and internal test datasets. The PCA-LDA and PLS-DA models maintained 100% accuracy on the independent test set, whereas the SVM model achieved a classification accuracy of 80% on the same set. These results reveal the volatile characteristics of Liupao tea and offer valuable insights for quality assessment and targeted flavor modulation.

Modern e-waste dismantling workshops showed substantially elevated BTH and BTR levels in indoor dust. • 2-OH-BTH predominated in dust, reaching 8100 ng/g in modern e-waste dismantling workshops. • 2-OH-BTH and 1-H-BTR dominated urinary profiles, with 1.8-fold higher concentrations in e-waste workers than rural residents. • BTH EDIs via dust ingestion were ∼ 24-fold higher in workers, yet dust contributed ≤2.33% of total exposure. • Significant intra- and inter-class correlations were observed for BTHs and BTRs in both dust and urine. Benzothiazoles (BTHs) and benzotriazoles (BTRs) are high production volume chemicals widely incorporated into electronic products, yet their environmental occurrence and potential occupational exposure during e-waste recycling remain poorly characterized. In this study, four BTHs and three BTRs were quantified in 113 dust samples collected from a modern e-waste recycling facility and 15 household dust samples, as well as in urine samples from 121 e-waste dismantling workers and 20 rural residents. The median Σ(BTHs+BTRs) in modern e-waste (e.g., cell phone) dismantling workshop dust (3000 ng/g) was approximately 9–10 times higher than that observed in traditional e-waste (e.g., refrigerator) dismantling workshop (350 ng/g), e-waste storage areas (260 ng/g) and suburb residential homes (300 ng/g). These findings indicate substantial accumulation of BTHs and BTRs in indoor dust associated with modern e-waste dismantling activities. 2-Hydroxybenzothiazole (2-OH-BTH) was the predominant congener in e-waste associated dust, accounting for more than 84–95% of Σ(BTHs+BTRs) across different microenvironments, compared with 73% in reference residential dust, suggesting relatively modest differences in congener profiles between recycling and residential environments. In urine, 2-OH-BTH and 1H-BTR were the predominant detected congeners, accounting for 83% and 67% of Σ(BTHs+BTRs) in workers and rural residents, respectively. Their median urinary concentrations in workers were 4.3 and 1.8 ng/mL, respectively, representing 1.8-fold higher levels than those in rural residents (2.4 and 1.0 ng/mL). Significant positive correlations were observed among BTHs, among BTRs, and between the two chemical classes in both dust and urine, suggesting shared or related exposure sources. The median estimated daily intake of BTHs through dust ingestion among workers was 2.60 ng/kg bw/day, approximately 24-fold higher than that estimated for rural residents (0.11 ng/kg bw/day), indicating elevated occupational exposure potential. Nevertheless, dust ingestion accounted for no more than 2.33% of the total BTH exposure estimated from urinary biomonitoring, suggesting that other exposure pathways may make greater contributions to overall internal exposure.

Firefighting protective clothing is an essential equipment that can protect firefighters from burn injuries during the firefighting process. However, it is still a challenge to detect the damage of firefighting protective clothing at an early stage when firefighters are exposed to excessively high temperature in fire cases. Herein, an ultralight self-powered fire alarm electronic textile (SFA e-textile) based on conductive aerogel fiber that comprises calcium alginate (CA), Fe3O4 nanoparticles (Fe3O4 NPs), and silver nanowires (Ag NWs) was developed, which achieved ultrasensitive temperature monitoring and energy harvesting in firefighting clothing. The resulting SFA e-textile was integrated into firefighting protective clothing to realize wide-range temperature sensing at 100–400 °C and repeatable fire warning capability, which could timely transmit an alarm signal to the wearer before the firefighting protective clothing malfunctioned in extreme fire environments. In addition, a self-powered fire self-rescue location system was further established based on the SFA e-textile that can help rescuers search and rescue trapped firefighters in fire cases. The power in the self-powered fire location system was offered by an SFA e-textile-based triboelectric nanogenerator (TENG). This work provided a useful design strategy for the preparation of ultralight wearable temperature-monitoring SFA e-textile used in firefighting protective clothing.

To solve metal resource shortage and alleviate environmental issues, it is in urgent need to explore cost-effective and environment-friendly adsorbents for sustainable recovery of valuable gold from e-waste. Herein, bacterial cellulose (BC) hybrid membrane grafted with adipic dihydrazide (ADH) has been fabricated via a facile schiff base reaction strategy for efficient and selective recovery of gold from complex aqueous media. The resulting [email protected] hybrid membrane features high ratio of hydrazide groups (67% of ADH by mass content) and hierarchical porous structure, ensuring high adsorption capacity (1149 mg/g) and fast adsorption equilibrium time (20 min) toward gold. Meanwhile, the remarkable recovery selectivity of gold is achieved in the simulated e-waste leachate containing a large amount of interfering metal ions. Notably, the captured Au(III) species on [email protected] hybrid membrane can be directly converted by redox-active hydrazide groups into Au(0) with no need of any external reductant. Furthermore, the developed [email protected] membrane possesses superior recycling and reusability performance, as reflected by no obvious decrease in gold extraction capability after six cycles. More importantly, the [email protected] hybrid membrane is capable of extracting almost 100% of gold from actual waste central processing unit (CPU) leachate, yielding high-purity gold (23.7 K) after pyrolysis.

Differentiating methicillin-sensitive and methicillin-resistant Staphylococcus aureus (MRSA and MSSA) is crucial for clinical diagnosis and anti-microbial treatment. Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) is an efficient tool for identifying pathogenic microorganisms at the bacterial species level. Here, we found that MRSA and MSSA can be differentiated by MALDI-TOF MS by employing (E)-propylα-cyano-4-hydroxyl cinnamylate (CHCA-C3) as the matrix, which shows great performance for proteins/peptides, especially hydrophobic proteins. The results show that the mass spectra profile of standard MRSA (ATCC 43300) is significantly different from the profiles of standard MSSA strains (ATCC 25923 and 29213) when using CHCA-C3 as the matrix compared to traditional matrix. The mass profiles had great reproducibility and were scarcely influenced by the growth medium. Due to the enhanced discrimination ability of CHCA-C3, we collected the mass spectra of 62 clinical S. aureus strains and selected four representative peaks for principal component analysis, which showed great differentiation. Our results suggest that employing a suitable matrix could enhance the discrimination ability of antibiotic-resistant bacteria by MALDI-TOF MS.

Topical eye drops still face challenges of low-drug treatment effects and frequent dosing in ophthalmic applications due to the low preocular retention rate and low transcorneal permeability. Thus, we designed and synthesized a phenylboronic acid conjugated chitosan oligosaccharide-vitamin E copolymer (PBA-CS-VE) for use in mucoadhesive voriconazole (VRC)-loaded nanomicelles for fungal keratitis. In vitro mucin binding and ex vivo eyeball adhesion tests show that the copolymer has strong mucoadhesion . The transportation of coumarin-6 (C6) across a monolayer of HCE-T cells and 3D cell spheroids confirm the strong corneal penetration ability of PBA-CS-VE. The mechanism of promoting corneal penetration was studied in terms of intracellular calcium-ion concentration, cell membrane potential, cell membrane fluidity, and the tight junctions of cells. The pharmacokinetics in the aqueous humor were examined to evaluate the ability of nanomicelles in promoting corneal penetration and prolonging ocular retention. VRC-loaded PBA-CS-VE nanomicelles (PBA-CS-VE-VRC) yielded a very favorable therapeutic effect on a rabbit model of fungal keratitis in vivo as compared to the free drug. Overall, the results indicate that PBA-CS-VE nanomicelles are a mucoadhesive candidate with enhanced transcorneal permeability and prolonged preocular retention for efficient delivery of topical ocular drugs. Statement of significance Although eye drops are widely used in ocular drug delivery, the disadvantages such as short retention time and weak corneal penetrating ability still seriously affect the therapeutic effect of the drug. Therefore, the mucoadhesive carrier seems to be an interesting strategy for ocular drug delivery. Herein, a novel phenylboronic acid conjugated chitosan oligosaccharide-vitamin E copolymer was designed and constructed as mucoadhesive nanomicelles loaded with voriconazole for fungal keratitis. These nanomicelles were able to improve the in vitro mucin binding and to prolong the residence time of the drug on the surface of the eyeball. Moreover, the nanomicelles exhibited an enhanced drug permeability in cell monolayer models and 3D cell culture models. This work provides a promising ocular drug delivery system.

A novel ternary PPy/P-C 3 N 4 /r-GO visible light-driven photocatalyst was fabricated via chemical polymerization of pyrrole in the presence of protonated-C 3 N 4 /reduced graphene oxide (P-C 3 N 4 /r-GO). The resulting PPy/P-C 3 N 4 /r-GO composite showed excellent photocatalytic performance under visible light for brilliant red dye (X3B) degradation and E. coli inactivation. An X3B degradation efficiency of 98% was achieved in 60 min, and an E. coli removal efficiency of 100% achieved in 90 min. Moreover, PPy/P-C 3 N 4 /r-GO displayed good recycling performance, with 90% efficiency retained over 5×3B photodegradation cycles. A plausible photocatalytic mechanism for the PPy/P-C 3 N 4 /r-GO composites was proposed, where p-n heterojunctions formed between P-C 3 N 4 and PPy effective separate charges (photoexcited electrons accumulating in the conduction band of P-C 3 N 4 , holes accumulating in the valence band of PPy), with r-GO acting as an electron acceptor and trap. The valence band holes in P-C 3 N 4 directly oxidize X3B, whereas conduction band electrons react with O 2 to generate reactive oxygen species (superoxide and hydroxide radicals) which also degrade X3B and can inactivate E. coli . This work thus introduces an efficient metal-free ternary photocatalyst system for environmental applications.

6-Shogaol is one component of ginger, which has been described to possess various health-promoting effects including anticancer, antiinflammatory, antioxidant and antiatherogenic. However, poor water solubility has limited the aforementioned health benefits and clinical applications of the drug. Herein, the aforementioned drawback was circumvented by the preparation of 6-shogaol-loaded liposome through thin-film dispersion method with TPGS as the carrier, in comparison with 6-shogaol liposome and free 6-shogaol. Appropriate indices were used for the characterization of the developed liposomes viz., particle size (PS), zeta potential (Z-potential), polydispersity index (PDI), entrapment efficiency (EE) and loading capacity (LC) while their morphologies were observed under the transmission electron microscopy (TEM). In-vitro dissolution investigation showed a substantial improvement in the accumulative release rates of liposomes comparable to the free 6-shogaol. The TPGS-modified 6-shogaol and 6-shogaol liposomes had oral relative bioavailability (RBA) of 580.04% and 281.55%, respectively, with improved t 1/2 , MRT, C max , AUC 0-t and T max . Pertinently, the TPGS coated 6-shogaol liposome may enhance the targeting of the drug to the brain. Therefore, the TPGS coated 6-shogaol liposome could potentially improve oral bioavailability of lipophilic drug in-vivo . More importantly, the results of tissue distribution investigation suggest that TPGS coated 6-shogaol liposome may act as promising carrier for brain delivery in future.
