Here, we present a universal preoxidation strategy to improve the impedance matching and the microwave absorption performance of a Ti₃AlC₂ MAX phase absorbing material. The microwave absorption properties of Ti₃AlC₂ particles were enhanced after preoxidation at temperatures of 500–700 °C for only 30 min in air, as compared with unoxidized Ti₃AlC₂ particles. More interestingly, the 600 °C-preoxidized Ti₃AlC₂ material reached a minimum reflection loss (RL_min) value of −50.56 dB at 8.87 GHz, superior to −12.36 dB at 12.82 GHz for the original Ti₃AlC₂ material. The preoxidized Ti₃AlC₂ particles were covered by a thin oxidation layer comprising both amorphous TiO₂ (a-TiO₂) and rutile TiO₂ (R-TiO₂). The oxidation layer endows the preoxidized Ti₃AlC₂ particles with good impedance matching, and a large number of nano-interfaces of a-TiO₂/R-TiO₂ and micro-interfaces of a-TiO₂/Ti₃AlC₂ also contribute to the dielectric loss mechanism, thus improving its microwave absorption ability. This work provides a practical strategy for the fundamental study and the optimal design of MAX microwave absorbing materials.</div></div>","PeriodicalId":48517,"journal":{"name":"Materials Today Nano","volume":"28 ","pages":"Article 100539"},"PeriodicalIF":8.2,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142663711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detailed structural studies confirm that these well-faceted nanowires are pure zinc blende single crystals, and there is a strict epitaxial relationship between the nanowire and the substrate.

The catalysts were synthesized using polydopamine as a carbon and nitrogen source via the solvothermal carbonization (STC) method, followed by pyrolysis and acid washing. The effect of solvothermal carbonization temperature (120, 150, and 180 °C) on the structure and ORR activity was investigated. The physicochemical characterization showed that higher STC temperatures reduced the size of copper crystallites, slightly increased the formation of copper(I) oxide, and led to the creation of well-dispersed copper single atoms/clusters at 150 °C. This optimal dispersion enhances the interaction between the copper single atoms and the reactants, leading to faster ORR kinetics, as demonstrated by the lower charge transfer resistance values in electrochemical impedance spectroscopy measurements. Additionally, the balance between micropore and mesopore structures at this temperature facilitates efficient mass transport, which is critical for achieving higher ORR activity. Moreover, accelerated stability tests showed excellent durability for Cu-150-NC, with negligible loss in onset potential after 10,000 cycles. The solvothermal process significantly increased the electrochemically active surface area (ECSA), with Cu-150-NC displaying the highest specific activity and mass activity per gram of copper, indicating superior performance.

Ordinary cotton fabrics were impregnated into PAM flame-retardant materials using a simple impregnation process. After the impregnation, the test was performed in a non-dropping state (simulating the thermal protection effect of PAM flame retardant materials directly acting on the outside of the human body at the fire scene). The results show that the PAM flame retardant material prepared by adding 4 wt% HCB has the best comprehensive performance. TPP test shows that spraying PAM flame retardant material on the outside of the fabric can instantly give the fabric a higher thermal protection performance. Under the total heat flux of 84 kW/m², the thermal performance protection value of the fabric is 2641.8 kW s/m², and the second-degree burn time can reach 31.45 s. PAM flame retardant material does not damage the fabric.

Hence, we have developed a nanoplatform with enhanced permeability that not only generates significant amounts of ROS but also converts them into longer-lasting reactive nitrogen species (RNS), thereby improving tumor therapy efficacy. In our study, carbon dots were functionalized by doping with gold atoms and grafting nitrosoglutathione (GSNO) to form ACN, which exhibits glucose oxidase-like properties and enables laser-responsive NO release. ACN and indocyanine green (ICG) were then loaded onto MnO₂ nanoflowers to form MnO₂@AI. Upon arrival at the tumor site, MnO₂ reacts with H₂O₂ and GSH, leading to its degradation and the subsequent release of ACN, which is characterized by three permeation-promoting properties: ultra-small size, positive charge, and NO content. In addition, ACN promotes H₂O₂ production through glucose metabolism and reduces pH, both of which enhance the Fenton-like reaction of MnO₂, thereby amplifying ROS generation. The ICG in MnO₂@AI enhances its photothermal properties, leading to the responsive release of NO from GSNO grafted onto ACN, which then reacts with the increased ROS to generate more toxic RNS. Collectively, the approach described herein offers substantial potential for advancing the treatment of malignant tumors.</div></div>","PeriodicalId":48517,"journal":{"name":"Materials Today Nano","volume":"28 ","pages":"Article 100532"},"PeriodicalIF":8.2,"publicationDate":"2024-10-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142527944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the conventional diagnostic methods to visualize microcracks in the tooth suffer from severe drawbacks, such as inaccurate cold stimulation, discomfort with probing, impractical staining techniques, and difficulty in distinguishing harmless craze lines from pathological cracks. To address this challenge, for the first time, we are proposing a novel approach by utilizing luminescent Ba₂ZnWO₆:Eu³⁺ (3 mol %), K⁺ (1 wt %) nanophosphor for improved imaging and diagnosis of cracked tooth syndrome. Herein, the double perovskite structured Ba₂ZnWO₆:Eu³⁺ (1–11 mol %), M⁺ (M⁺ = Na, K, and Li (1 wt %)) nanophosphors were synthesized via the sonochemical route. The photoluminescence emission spectra of the prepared Ba₂ZnWO₆:Eu³⁺ (1–11 mol %) nanophosphors displaying distinct peaks at 583, 595, 613, 662, and 720 nm, which ascribed to transitions from state ⁵D₀ to ⁷F_J (J = 1–4) state of the Eu³⁺ ions, respectively. By adopting a strategic charge compensation mechanism, the enhancement in the luminescence emission intensity of about 1.5-fold was achieved after co-doping K⁺ (1 wt %) with Ba₂ZnWO₆:Eu³⁺ (3 mol %) nanophosphor. The photometric studies of the phosphors portray their orange-red emission with excellent quantum efficiency (82.52 %), and color purity (∼ 99 %).
