Summary: The interactions of toxic dye, thioflavin T, with different forms of clay and clay minerals were studied. The uptake of dye was higher in the pristine clay and clay minerals compared to their organically modified forms. The dye was found to be mainly on the surface of the clay minerals, supported by changes in zeta potential values and particle size. The extracted colored residues were used as colorants for polymer films with enhanced characteristics, preventing the accumulation of second-generation waste materials.

Summary: This study investigates the correlations between semiconductor type and gas sensing properties in soluble acene/polymer blends, and demonstrates an unusual solid-state morphology that is effective for amperometric gas sensing performance. The blend film of 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS-pentacene)/poly(fluorine-co-triarylamine) (PTAA) shows uniformly mixed phases due to similar solubility and surface tension. The blend film of 2,8-difluoro-5,11-bis(triethylsilylethynyl) anthradithiophene (diF-TES ADT)/PTAA exhibits phase separation and a crater-like via hole structure of PTAA, allowing selective penetration of the target NO2 gas and enhancing sensitivity towards NO2. The findings provide protocols for fabricating high-performance field-effect transistors and gas sensors in a blending system.

Summary: This study reports a facile carbon doping strategy to enhance the phase transition of MoS2 and explains the counterintuitive directionality of the transitions using density functional theory calculations. The results show that the existence of carbon as interstitial atoms is more favorable to the phase transition, and the heterogeneous interfaces between 2H and 1T or 1T' are more conducive to charge transfer. The trinary-heterostructure nanofilm exhibits excellent electrocatalytic activities, providing insights into the phase transition mechanism of 2D transition metal dichalcogenides and guidance for scalable production of trinary-heterostructure electrocatalysts.

Summary: In this study, humidity-independent alpha-Fe2O3/ZnFe2O4 (FZFO) hetero-junctions with strong magnetism were prepared for N-butanol gas detection, potentially serving as electronic noses for early lung cancer screening. The magnetism of FZFO allows for more oxygen capture and redox, while the n-n heterojunctions greatly enhance gas sensitivity, even responding to 0.1 ppm at 160 degrees Celsius. The FZFO-4 sample has a detection limit of 1 ppb, meeting accuracy requirements, and both FZFO-2 and FZFO-4 samples maintain humidity independence at 91% relative humidity, minimizing the influence of water vapor exhaled by patients. This work introduces FZFO heterojunctions as electronic noses for lung cancer screening, potentially revolutionizing non-invasive diagnosis.

Summary: Sulfide compounds show promise as electrocatalysts for water splitting, but their performance is limited by factors such as limited active sites and hindered substance transport. This study successfully prepared a high-entropy sulfide (ZnCoMnFeAlMg)(9)S-8, which reduced grain size and increased specific surface area, enabling the realization of a dual-functional catalyst with multiple catalytic sites. High entropy also modulated the electronic properties of sulfides, reducing the potential energy barrier for hydrolysis. This research introduces a new approach for functionalizing high entropy nanomaterials and improves the performance of water splitting catalysts.
