In this work, Ecoflex was used as the main material for flexible devices, and a charge capture layer with both triboelectric and piezoelectric effects was prepared by doping with tetragonal barium titanate (T-BTO). An electrode with charge capture functionality was created by doping with carbon spheres (CS). Additionally, a layer-by-layer self-assembly process was employed to construct a piezoelectric effect-enhanced integrated triboelectric nanogenerator Ecoflex/CS/T-BTO (CTB-TENG). By polarization treatment, the output voltage and current of the CTB-TENG were enhanced to 532 V and 72 μA. To enhance the tactile sensing capability of the CTB-TENG, a deep learning model based on convolutional neural networks was proposed, achieving an object recognition accuracy of 98.6 %. Based on this, an active tactile sensing system and a passive tactile control system based on CTB-TENG were developed. The active tactile sensing system achieved intelligent sorting of objects, while the passive tactile sensing system enabled detection and control of objects. This lays a solid foundation for the further application of CTB-TENG in the fields of smart factories and smart homes. It also provides broader application prospects for tactile sensors based on the triboelectric effect and contributes to the advancement of flexible electronic technology.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"28 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study introduces a novel therapeutic approach targeting glucose utilization, and develops an acid-stable adhesive hydrogel co-loaded with glucose oxidase (GOx) and allicin (AG@G). This enables sustained and simultaneous intervention in tumor and bacterial proliferation within tumor. Allicin, a traditional Chinese medicine (TCM) extracted from garlic, exhibits dual efficacy by inhibiting both tumor growth and bacterial proliferation, while GOx catalyzes glucose consumption, depleting cellular energy reserves and initiating NADPH-mediated disulfidptosis. The synergistic combination of allicin and GOx amplifies intracellular disulfide stress and oxidative stress, effectively triggering disulfidptosis and ferroptosis. <em>In vivo</em> studies confirm the potent antitumor activity of AG@G, effectively suppressing the growth of tumor and associated microbiota in breast cancer, even in the drug-resistant lung cancer. Notably, AG@G treatment prevents lung metastasis of breast cancer and the homing of subcutaneous osimertinib-resistant lung cancer.

A few nanometers thick hydrochar layer was uniformly coated on the surface of TiO<sub>2</sub> nanoparticles, with Ti-O-C bonding linkage and abundant oxygen vacancy defects at the interface. HC-TENPs/H<sub>2</sub>O<sub>2</sub>/visible light system can efficiently degrade various nitrogen heterocyclic compounds (pyridine, quinoline, benzoquinoline, pyrrole, indole, and carbazole) at ambient temperatures and pressures. The hydrochar hybridization narrowed the bandgap of photocatalysts, broadened the range of light absorption, and enhanced the separation of photogenerated charge carriers and photoelectric response. Hydroxyl radicals, superoxide radicals, and singlet oxygen are recognized as reactive oxygen species, in which singlet oxygen contributed over 60% to quinoline degradation. The oxygen vacancy defects served as the centers to trap superoxide radicals where they were oxidized to singlet oxygen by holes.

Despite its significance, there are few clear and environmentally friendly methods for directly managing this interface. In this study, a value-added wood waste recycling method is introduced that creates a porous carbon structure (Pc-S) on the aggregate surface. This modification process uses thermal cross-linking technology, in which biochar is converted at high temperatures into carbon on the aggregate surface in an activation reaction.

This carbon modification of granite not only fortifies the interface but also enhances its water intrusion resistance by over 78.9 %, outperforming basalt, which is one of the best aggregates for pavement construction. Moreover, using these modified aggregates in road construction can lead to negative carbon emissions, estimated at 349.23 tCO<sub>2</sub>/km.

The simulation results, validated by experimental measurements, demonstrate that rough foams achieve a 60.08% to 104.28% increase in heat transfer efficiency due to increased specific surface area and intensified flow disturbance caused by the micro-rods. However, the addition of micro-rods also increases pressure drop due to impeding flow, expanding low-pressure areas, and generating local eddies. Despite these drawbacks, rough foams still demonstrate superior comprehensive thermal efficiency, with an average improvement of 44.47% to 82.90% under <em>iso</em>-pumping conditions.

To pursue a sustainable end-of-life solution for TPU-based products, self-disintegrating biocomposite TPUs have recently been developed by embedding spores of TPU-degrading bacteria into TPUs via melt extrusion. Herein, we improve upon spore-bearing biocomposites and demonstrate industrially relevant manufacturing conditions for fabricating biocomposite TPUs. To minimize the coloration of biocomposite TPUs, spore production was modified. The innate brown color of the resulting materials was diminished by reducing FeSO<sub>4</sub> in sporulation media, generating white spores without compromising spore productivity, viability, morphology or heat-shock tolerance. Biocomposite TPUs containing white spores displayed a 45 % increase in toughness compared to TPUs without spores, while retaining ∼ 90 % spore viability post processing. Furthermore, biocomposite TPU fabrication was demonstrated using a scalable continuous extruder followed by injection molding. Biocomposite TPUs generated by these industry-relevant processes exhibited comparable toughness improvement and spore viability to biocomposite TPU prepared using a lab scale microcompounder, while enhancing productivity by 30-fold. Finally, spore addition significantly improved the recyclability of biocomposite TPUs, enabling 80 % toughness retention after 5 rounds of iterative melt processing. Additionally, no negative effect on the lifespan of the generated TPUs was observed over 1 year of storage. Overall, this study confirms that spore-bearing biocomposite TPUs are promising for practical applications, offering an accessible method to enhance toughness and sustainability of commercial TPUs through the incorporation of spore-based living fillers.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"8 1","pages":""},"PeriodicalIF":15.1,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143020320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
