Summary: The purpose of this study is to investigate the charge transfer process and SERS enhancement mechanism in the Ag/MBA/PAN system with varying thicknesses of PAN. The results show that increasing the PAN thickness leads to higher frequency and intensity of the characteristic MBA band, as well as increased intensity of the b2 mode. The degree of CT also increases with increasing PAN thickness, due to the excited SPR from Ag. The electromagnetic enhancement mechanism at the PAN/Ag interface generates hot electrons and facilitates electron transfer in the CT process.

Summary: A simple approach to fabricate large-scale optoplasmonic hybrid materials (OHMs) for high sensitivity surface-enhanced Raman spectroscopy (SERS) is proposed. The OHM consists of a metal film, a monolayer of nanoparticles (MFON), and a microsphere. The excited wavelength of the localized surface plasmon resonance in the MFON can be controlled by the size of the nanoparticles and an additional dielectric layer. Under specific conditions, Raman signals of low concentration methylene blue can be detected. Numerical simulations show that the OHM provides enhanced sensitivity compared to traditional plasmonic nanostructures.

Summary: EC-SOERS is a new phenomenon that enhances the Raman signal during the oxidation of a metal surface. Studies show that carbonyl and carboxyl groups are necessary to observe this phenomenon, with a delocated charge being important factor. Evaluating the enhancement factors for different molecules with highly delocated charge and a carboxyl group sheds more light on the interaction of molecules with the electrochemically generated SOERS substrates.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
