“…Note that the molar masses of the PNCI#s were controlled within a narrow range of 448-461 kg mol −1 to ensure a fair comparison with the PVDF binder. [37] We intentionally targeted the high molecular weights within the controllable range to maximize cycling performance by achieving robust mechanical strength and strong adhesion properties. [37,38] As revealed by DSC, the T g values of the PNCI#s were in the range of 39-48 °C, which ensures mechanical robustness at room temperatures (Figure S7, Supporting Information).…”

Nickel‐rich layered oxide, LiNixCoyMnzO2 (NCM, x > 0.8), has emerged as a promising cathode material for lithium‐ion batteries due to its high specific capacity and energy density. However, there remains a challenge regarding NCM degradation during cycling, associated with interfacial side reactions and microcrack formation. Herein, a functional poly(norbornene‐co‐norbornene dicarboxylic acid‐co‐heptafluorobutyl norbornene imide) (PNCI)‐based binder system is introduced, with controlled functionalities and monomer compositions, to preserve the structural integrity of NCM. The PNCI binder system incorporates three different norbornene‐derived monomers with distinct functionalities, allowing for multifunctionality, including electro‐chemo‐mechanical stability, strong adhesion, and dispersibility. By systematically adjusting the molar composition of the PNCI binders, the overall binder characteristics are fine‐tuned, optimizing the adhesion and dispersion of electrode components. The optimized PNCI binder, with desired adhesion strength, surface energy, and polarity, plays a crucial role in facilitating the formation of a uniform electrode structure with a high areal mass loading of NCM, ensuring long‐term cycling stability. This study highlights the significance of striking a balance between functionalities and composition in binder systems to achieve high‐performance NCM cathodes.

“…Recently, Janus materials have attracted tremendous attention in various applications such as functional surfactants, photoelectric materials and catalytic agents due to its two distinct faces with anisotropic properties [14][15][16]. Among these Janus-type materials, the twodimensional (2D) ones with asymmetrical properties on each side are called Janus film [16].…”

AuNPs monolayer doping Poly(3,4-ethylenedioxythiophene):polystyrenesulfonate (PEDOT : PSS) film on interdigitated electrode had been fabricated into AuNPs/PEDOT : PSS Janus film sensor to detect hydrogen sulfide (H 2 S). The results show that the Janus film sensors have a wide measurement range of H 2 S concentration. The sensitivity of PEDOT : PSS/AuNPs sensor grows up with the thickness of Janus film increases. The resistance response of AuNPs Janus film was affected little by the rough surface states of PEDOT : PSS film. In addition, the PEDOT : PSS/AuNPs film sensor had been used again to detect H 2 S. This work presents a platform to inspire a novel high sensitive chemiresistive sensor via nanoparticles monolayer.

Noncentrosymmetric nanostructures are composed of two different materials displayed on spatially distinct surface regions. These nontrivial building blocks facilitate self-assembly of hierarchical nanostructures with increased complexity and support cooperative material behaviors. The arrangement of M13 bacteriophage structural proteins within its capsid creates a promising monodisperse and readily modifiable template for these low-symmetry nanomaterials. Here, a 9-mer ZnS-binding peptide was inserted into the p3 minor coat protein (capsid tip) of an M13 bacteriophage with Au-binding motif fused to its p8 major coat protein (capsid body). Multiple vortex/rest cycles with chloroform were used to convert this bifunctional, Au/ZnS (p8/p3)-binding phage from filament to spheroid. The shape transformation was studied with transmission electron microscopy, circular dichroism spectroscopy, and fluorescence spectroscopy. The effects of the p3 peptide fusion and conversion temperature were evaluated. Compared to the Au-binding phage without a p3 peptide fusion, the insertion of the ZnS-binding motif increased spheroid size, molar ellipticity loss, and intrinsic fluorescence quenching. Reduced temperature (0 °C) within early transformation cycles diminished spheroid polydispersity and increased agglomeration resistance. In addition, Au/ZnS-binding spheroids retained peptide motif affinity and relative placement of the p3 and p8. Site-specific synthesis of ZnS and Au on the p3 and p8, respectively, produced noncentrosymmetric hybrid metal/semiconductor nanostructures. This work highlights the effect of a p3 mutation on filament to spheroid transformation as well as the importance of temperature in producing a robust scaffold for inorganic material synthesis. Finally, the manufactured bifunctional M13 spheroids were used for the biodirected synthesis of noncentrosymmetric nanoparticle assemblies demonstrating the potential for heterojunction formation.
