MSC sandwich structure’s limitation includes short circuit with two electrodes, electrodes should be loaded with as many active materials as possible to improve the energy storage capacity of the device, both of which will increase the ion transfer impedance, resulting in low power density. On the other hand, the sandwich structure is difficult to integrate into micro electronic devices. In recent years, the cross-fertilization of electrochromic technology with other fields has given rise to a variety of emerging smart devices and technologies by combining with supercapacitors, smart energy storage devices and smart windows. This paper focuses on hybrid of MSC and electrochromic device structure to verify bifunctional device structure by asymmetric interdigital electrodes. They require same hydrogel and electrode layer to enhance their performance, which are pursued with reduction in width, size, power consumption and price in the field of portable, etc. The material of Ag/Carbon/PVA/KCL/PEDOT:PSS(ACPKP)for new structure will be printed as to ensure device’s energy-storage and display. As expected, the micro-supercapacitor based on PET film can deliver areal capacitance up to 6.5 mF/cm2. Even if, micro-supercapacitor undergoes continuous 800 cycles, the performance of device can still remain nearly 79.4%. With printing technology, low cost, large area and green products demonstrate its great application in next-generation flexible electronics.","PeriodicalId":18230,"journal":{"name":"Materials Science","volume":"31 4","pages":"441-445"},"PeriodicalIF":0.0,"publicationDate":"2025-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://matsc.ktu.lt/index.php/MatSc/article/download/38544/17407","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147895680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thoracoscopic surgery, as a new minimally invasive technique in thoracic surgery, is of great significance in exploring the postoperative recovery quality of patients undergoing this surgery. Therefore, this study uses micro controlled flow spinning technology to prepare a calcium alginate fiber coating (CaAFC) film using materials such as sodium alginate (SA). Combined with thermal insulation nursing during the recovery period, the effect of this film was explored in patients undergoing thoracoscopic general anesthesia surgery (TGAS), and it was applied in animal experiments simulating TGAS. The results showed that the permeability of the CaAFC was 93 g/m2·24 h, the porosity was 73 %, and the water absorption rate was 21.5 g/g, demonstrating good breathability and water absorption. The relative growth rate (RGR) of HaCaT cells under CaAFC was 1.52, and the stress fiber staining intensity (SFSI) was 1.31, both of which were higher than the other two dressings. These findings indicated that the material was non-toxic to cells and could significantly improve cell activity. The wound healing rate of mice treated with CaAFC on the 15th day after surgery was 96.3 %, which was significantly higher than that of mice treated with traditional alginate medical dressings (TAMD) and medical gauze (MG). These results indicated that CaAFC could promote wound healing. The above results indicate that the CaAFC has good breathability, water absorption, and antibacterial properties. Moreover, it can significantly promote wound healing, increase cell activity, reduce postoperative infection risk, and provide support for improving postoperative care for patients undergoing thoracoscopy surgery in clinical practice.","PeriodicalId":18230,"journal":{"name":"Materials Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://matsc.ktu.lt/index.php/MatSc/article/download/41091/17070","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147909403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the storm water management model (SWMM) and environmental fluid dynamics code (EFDC) coupling model, the water quality changes of Xinfeng River under different scenarios of reclaimed water supply were simulated. The model was calibrated and verified through historical monitoring data, and the results showed that chemical oxygen demand (COD) could stably meet the Class V water quality standard, while NH3-N and total phosphorus (TP) could not meet the standard. Secondly, NH2-MIL-125(Ti) and NH2-UIO-66(Zr) were synthesized in this study. The morphology, structure, and properties of MOFs were characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), and thermogravimetric analysis (TGA), and they were used for adsorption and removal of phosphorus in water environments. The results indicate that NH2-MIL-125(Ti) has a larger adsorption capacity (10.42 mg/g), and the adsorption of phosphorus by NH2-MIL-125(Ti) and NH2-UIO-66(Zr) is more in line with the quasi second order kinetic model, and their adsorption isotherms are more in line with the Freundlich model. In addition, both adsorbents have good adsorption regeneration performance, with a phosphorus removal rate of over 85 % after 5 cycles. The water quality simulation model constructed in this study can accurately predict the impact of recycled water supply on river water quality. The selected MOFs materials have good phosphorus adsorption and removal performance, providing a scientific basis and technical support for improving water quality and controlling phosphorus pollution in recycled water supply rivers.","PeriodicalId":18230,"journal":{"name":"Materials Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://matsc.ktu.lt/index.php/MatSc/article/download/41345/17035","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147917243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The MnO₂/citric acid system proved most effective, attributed to its one-step reaction to generate primary free radicals. Optimal reaction conditions were determined as a molar ratio of AA to TPEG (Mn=2400) of 3.5:1.0 and [MnO₂]:[citric acid] of 1:1. The longer side chains of MPCE enhanced adsorption on cement particles and dispersing performance via steric hindrance. Cement paste containing MPCE-2400 showed superior dispersing ability, retention capacity, clay resistance, and hardened mechanical properties.

To address this issue, a stress luminescent material based on NaNbO3:Pr3+ was developed and applied in anti-counterfeiting devices. Experimental results demonstrate that compared to undoped NaNbO3, the Pr3+-doped material exhibits new absorption peaks within the 350 – 500 nm range. The stress luminescence intensity of the material increases initially and then decreases with rising annealing temperatures and Pr3+ doping concentrations. The optimal annealing temperature and doping concentration, yielding the highest stress luminescence intensity, were identified as 1075 °C and 0.7 %, respectively. Additionally, while the luminescence intensity of NaNbO3:Pr3+ diminishes with repeated friction, its luminescent performance is restored after UV irradiation. In anti-counterfeiting device testing, the device incorporating 1075 °C annealed NaNbO3:0.7 %Pr3+ was able to effectively capture variations in the writer’s force during the writing process. This capability reflects the writer's unique writing habits, thereby enhancing the anti-counterfeiting effectiveness of electronic signatures.

Therefore, it is very important to develop a non-noble metal catalyst with low cost, high catalytic activity and high stability for hydrogen production from water electrolysis. Up to now, transition metal sulfides, oxides, carbides, nitrides and phosphates have been proven to have good electrocatalytic activity. Among them, bimetallic phosphates have become the research hotspot in this field because of their high catalytic activity compared with others. In this study, transition metal salts, urea and ammonium fluoride were used as raw materials for in situ growth of transition metal dihydrohydride NiCo2/LDH on NF substrate based on hydrothermal reaction, the bimetallic phosphates NiCo2/NF grown on the NF substrate were obtained. The experimental results show that the prepared NiCo2P/NF catalyst exhibits excellent electrocatalytic performance. In alkaline media, a catal current density of 10 mA/cm2 can be obtained at an overpotential of 97 mV, with a Tafel slope of only 21 mV/dec. Moreover, its electrocatalytic activity can be maintained for more than 10 h, which is consistent with the before the experiment. This is mainly attributed to: the NiCo2P/NF derivative possesses the characteristics of a multimetal phosphide derived from transition metal elements Ni and Co after hydrothermal and phosphidation treatment. Its nanowire urchin-like heterostructure exposes more catalytically active sites, effectively promoting mass transfer and charge transfer accelerating the hydrogen evolution kinetics reaction process, and enhancing the catalytic performance with high catalytic stability.","PeriodicalId":18230,"journal":{"name":"Materials Science","volume":"31 3","pages":"324-330"},"PeriodicalIF":0.0,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://matsc.ktu.lt/index.php/MatSc/article/download/39603/16926","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147331588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To enhance nZVI’s removal performance, sulfurization and sodium carboxymethyl cellulose (CMC) modifications were applied. Three preparation methods were used to create modified nZVI materials with distinct structures, and their removal efficiencies were compared. Results showed that the nZVI modified via surface corrosion achieved the highest removal efficiency. Furthermore, the study explored the effects of various factors on the removal efficiency, including the molar ratio of sulfurizing agent to iron, initial pH, reaction temperature, the dosage of modified nZVI, and the initial concentration of hexavalent chromium. The results showed that the highest chromium removal rate (96.97 %) was achieved when the molar ratio of sulfurizing agent to iron was 0.4, the initial pH was 3, the reaction temperature was 25 ℃, the dosage of modified nZVI was 52 mg/L, and the initial hexavalent chromium concentration was 12 mg/L. After three cycles of reuse, the modified nZVI material still maintained a removal rate of 94.73 %. Additionally, the presence of various ions in wastewater was found to influence the removal efficiency. The effect of anions was minimal and could be neglected, while the presence of cations, particularly Mg2+, had a significant impact on removal performance.
