Polymeric dielectric layers are pivotal in the implementation of organic electronics due to their inherent deformable characteristics as well as outstanding insulating performance. Here, the review highlights an innovative technology termed initiated chemical vapor deposition (iCVD) for synthesizing polymer dielectric materials, particularly in the context of organic thin-film transistors (OTFTs). The all-dry polymer deposition process circumvents issues associated with conventional solvent-based methods, such as residual solvent, potential damage to the substrate, and the lack of large-area uniformity, allowing for ultra-thin, high-purity polymer dielectric layers with exceptional dielectric performance comparable to inorganic dielectrics. Furthermore, iCVD process enables the incorporation of various chemical functionalities into the dielectric layer, which enables the generation of versatile, high-performance organic electronic devices.

Chalcohalide exhibit high charge carrier mobility, defect tolerance, strong absorption characteristics, and tunable optical and electrical properties owing to their unique electronic configurations and diverse compositions. Specifically, chalcohalide nanocrystals synthesized via solution-phase enable tunability of uniform size, shape, and composition, and offer colloidal stability when dispersed in various solvents. Solution-processable chalcohalide nanocrystals offer a simple and cost-effective route for device fabrication while preserving their unique size and shape-dependent properties.

However, the traditional model of large-scale nuclear reactors has encountered significant barriers, including high financial risks, stringent safety concerns, and a lack of adaptability to smaller electrical grids, and changing energy markets. With over 70 types of SMRs currently under development globally, this study reviews several prominent models to assess their general characteristics and potential advantages. Through simple physical and economic models, the paper evaluates the impact of reducing reactor size on efficiency, safety, and cost, highlighting the shared traits and innovations across different SMR designs. The findings indicate that SMRs could address many of the limitations of conventional nuclear power, offering more flexible, scalable, and economically viable options for electricity generation.

They are crosslinked with CYKC peptide through a thiol-ene click reaction. The synthesis of the CYKC peptide and its cleavage by α-chymotrypsin were confirmed using high-performance liquid chromatography (HPLC). Additionally, the in vitro release behavior was accurately monitored using the micropatterning method, demonstrating the stable immobilization and successful sustained release of 5-FU upon the addition of α-chymotrypsin in micropatterned PHcd hydrogel.
