Therefore, enhancing its water repellency and anti‐icing capabilities is essential. In this work, a photothermal superhydrophobic Al 2 SiO 5 FP coated with MWCNT@SiO 2 aerogels is presented featuring highly porous hierarchical micro/nanostructures, fabricated using a simple, rapid, and fluorine‐free spraying technique. The as‐prepared superhydrophobic surface exhibits excellent water repellency, superior self‐cleaning ability, and outstanding mechanical and chemical durability. Notably, it retains high insulation performance even under wet conditions. Furthermore, the surface demonstrates remarkable photothermal properties, achieving ≈95.7% light absorption. Under one‐sun irradiation (1 kW/m 2 ), it reaches a peak temperature of 102.6°C, confirming efficient solar‐to‐thermal energy conversion. Anti‐icing evaluations reveal that the surface delays ice formation by a factor of 3.7 compared to the pristine Al 2 SiO 5 FP substrate, indicating robust passive anti‐icing capability. Subsequent photothermal de‐icing tests demonstrate that the surface effectively melts ice layers, facilitating rapid and energy‐efficient ice removal. Consequently, this multifunctional superhydrophobic coating greatly broadens the practical applications of aluminosilicate fiber paper in harsh environments.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"222 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147908084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Characterization analyses reveal their rich porous structure and large specific surface area, which facilitate the adsorption and desorption of target gases. Gas sensing performance tests demonstrate that the sensor exhibits high sensitivity and good selectivity towards formaldehyde gas. At 120 °C, the response to 100 ppm formaldehyde reaches 22.18%. The response and recovery times are 4 s and 8 s. Additionally, the sensor exhibits a linear response over the concentration range of 5–100 ppm formaldehyde, indicating its potential application value in environmental monitoring and smart home areas. Density functional theory calculations suggest that the strong electronic interaction between 3D rGO/MXene and formaldehyde effectively promotes molecular adsorption and activation. This orbital coupling and charge transfer mechanism form the electronic structure basis for the material's excellent response capability.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"222 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147906343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its findings show that incorporating bimetal elements significantly reduces the energy barrier value: from 0.59 eV for undoped crystal to 0.09 eV for Li/La and 0.20 eV for Li/Ti dopant, respectively. Furthermore, this study assesses the impact of bimetal doping on the structural characteristics, morphology, and thermal storage properties using techniques such as X‐ray diffraction, scanning electron microscopy, and thermogravimetric analysis.

Surface properties affect the osseointegration of implants; however, the surface for the optimal osseointegration is still being researched. Herein, the surface roughness and topography of dental implant screws after polishing, sandblasting, and laser treatment via tapping‐mode atomic force microscopy are investigated. The measurements are performed at the implants’ shank, crest, and root sites and evaluated for surface roughness, kurtosis, and skew values. Laser‐treated and sandblasted samples have a significantly higher roughness compared to the machined sample. The roughness at the root of the samples is higher in case of the laser‐treated and machined samples, while lower for the sandblasted implant. It is found that laser treatment leads to a roughness lower than that of sandblasted dental screws but significantly higher than that of mechanically polished implants. Differences in the roughness at different topological sites show the need for more precise treatment of implants in order to optimize the roughness.","PeriodicalId":87717,"journal":{"name":"Physica status solidi (A): Applied research","volume":"308 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79689305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Not only daily nutrition plays an important role, but also the so called “pellicle” on the outer surfaced of teeth, which is mainly formed by saliva proteins. Moreover, numerous bacteria are part of this pellicle, which might cause caries by acidic metabolites. In the here presented study, a method for electrophoretic deposition (EPD) of hydroxyapatite (HAP) nanoparticles on gold surfaces, suitable for Surface Plasmon Resonance (SPR) measurements has been developed. An “artificial tooth” has been created and loaded by natural saliva in different concentrations (to form a natural pellicle), while the influence of an environment with different pH values has been studied. It could be demonstrated that even slight acid solutions damage the pellicle significantly within seconds, exposing the HAP to acidic degradation, which would lead to caries in the human oral cavities. This model allows to study pellicle formation as well as degradation in real time. As a practical example, the influence of beverages on the pellicle could be demonstrated.This article is protected by copyright.

Further, the processing maps were constructed at different strains based on dynamic material models, from which the feasible processing window of the experimental alloy was determined in the areas of deformation temperatures of 425‐450 °C and strain rates of 0.01‐0.1 s‐1.This article is protected by copyright.
