Summary: The composite of nanoporous Si particles and Li3PS4 solid electrolyte can effectively mitigate the volume expansion of Si, maintaining low interfacial resistance and high cycle stability. In contrast, non-porous Si composite anodes tend to form large cracks at the Si-Li3PS4 interface, leading to low capacity retention. This microscopic study provides the first evidence that nanoporous structure can alleviate the volume change of Si.

Summary: This study reveals that the issues with carbon nanotubes (CNTs) in flexible lithium-ion batteries (LIBs) are caused by excessive decomposition and destructive intercalation of solvated Li+, due to their large electrochemical surface area and defects. It further demonstrates that solvated Na+ is less solvated than solvated Li+ and has poor affinity with graphitic carbon materials. By replacing solvated Li+ with solvated Na+ in the first cycle, an ultrathin NaF-containing solid electrolyte sieving layer can be formed on the CNTs, isolating them from solvated Li+ and suppressing the formation of thick SEI and destructive intercalation of solvent molecules. The Si/CNT electrode with this NaF-containing solid electrolyte sieving layer exhibits excellent flexibility and high specific capacity.

Summary: This study introduces TEMPO-oxidized nanofibrillated cellulose (ONFC) with charged carboxyl groups for the efficient exfoliation of two-dimensional MoS2/graphene composites. With the assistance of ONFC, the exfoliated MoS2/graphene increases gradually in the aqueous dispersions. Self-standing flexible films of MoS2/graphene/ONFC/CNTs are constructed using ONFC as a fibrous skeleton and CNTs/graphene as an electrical network. The electrode materials based on natural cellulose show potential for green electronics with high flexibility and increased portability.

Summary: This paper investigates the combination of gold nanoparticles and tantalum-doped titanium dioxide films to control the modulation of plasmonic resonance. The study found that in a specific embedding geometry, the plasmonic resonance of gold nanoparticles is significantly blueshifted with increasing tantalum content. Despite the films' defects, Au-Ta:TiO2 nanocomposites show promise as highly tunable plasmonic conductive metamaterials for advanced light management.

Summary: The photo-induced enhanced Raman spectroscopy (PIERS) effect occurs when plasmonic nanoparticles on a semiconductor are illuminated by UV light before Raman measurement. The PIERS effect typically lasts for about an hour, with the proposed mechanism being the creation of oxygen vacancies in the semiconductor to facilitate charge transfer. However, this hypothesis has not been experimentally confirmed. In this study, gold nanoparticles co-deposited with porous TiO2 as a PIERS substrate exhibit the highest measured intensity and significantly longer duration (at least 8 days). Cathodoluminescence measurements reveal two distinct mechanisms for co-deposited and drop-casted gold nanoparticles, with the oxygen vacancies hypothesis leaning towards confirmation for the latter, while the narrowing of the depletion zone explains the prolonged PIERS effect.

Summary: Authors utilized synchrotron-based UV resonance Raman spectroscopy to study intensity behavior of multiple phonons scattering in H-capped polyynes and demonstrated size-dependent electron-phonon coupling. By exciting each H-terminated polyyne to the maxima of its vibronic absorption spectrum, they could precisely determine electronic and vibrational structure of the ground and excited states for the main observed vibrational mode. The determined Huang-Rhys factors indicated a strong and size-dependent electron-phonon coupling increasing with the sp-carbon chain length.

Summary: In this study, nanostructured ZnMn2O4 thin films were synthesized using pulsed laser deposition (PLD), and the effects of deposition and annealing conditions on the film properties were evaluated using various characterization techniques. The study revealed the modulation of film porosity by oxygen pressure and the combined effect of deposition pressure and annealing temperature on tailored properties of the film. The influence of film porosity on the voltammetric behavior of the film at higher scan rate was also highlighted. The research confirmed the complex electrochemical mechanism of ZnMn2O4 material and paved the way for nanoscale design of engineered ZnMn2O4-based electrodes.

Summary: Among post-lithium ion battery technologies, rechargeable chemistries with Zn anodes are promising due to their high energy density, low cost, material availability, and safety. However, Zn anodes in aqueous electrolytes face challenges such as hydrogen evolution, passivation, and shape changes. Deep eutectic solvents (DESs) are green and low-cost non-aqueous solvents that can address these issues. This study investigates the electrochemistry of Zn in hydrated DESs and proposes an optimized electrolyte based on fundamental electrochemical data, morphology evaluation, and modeling of the cycling response.

Summary: Ultrafast plasmonics is gaining attention for exploring new plasmonic materials that overcome the limitations of noble metals. Titanium nitride (TiN) is particularly notable due to its refractory properties and extremely fast electron-lattice cooling time (<100 fs) compared to gold (approximately 1 ps). However, the exact explanation for the ultrafast and giant optical response of TiN-based materials under femtosecond laser excitation is still unknown.

Summary: The research on molybdenum disulphide (MoS2) has made significant progress in the past decade due to its potential applications in future ultrathin optoelectronic devices. Raman spectroscopy has been widely used to characterize the structure of MoS2 films, but the effects of MoS2-metal interaction on its vibrational properties are still not fully understood. Studying this subject with experimental and theoretical methods is essential for understanding the interface physics of MoS2-metal systems and developing metal-assisted synthesis methods. This review summarizes the main findings of Raman spectroscopy studies on heterosystems between MoS2 and transition metals, providing a foundation and directions for future research.

Summary: In this work, the growth of WS2/MoS2 and MoS2/WS2 heterobilayers by pulsed laser deposition (PLD) under ultra-high vacuum conditions was studied. The heterobilayer morphology and structure at the nanoscale were investigated using in situ scanning tunneling microscopy. The experiments showed that the growth of the heterostructure can be controlled by tuning the number of laser pulses, achieving high coverage and thickness sensitivity. Raman spectroscopy revealed the effect of the interaction with the metallic substrate on the TMD vibrational properties and a strong interlayer coupling between the MoS2 and WS2 layers. The transfer of the heterobilayers onto a silica substrate confirmed that the interlayer coupling is not substrate-dependent. This work highlights the potential of PLD technique in growing TMD heterostructures and opens new perspectives in the synthesis of complex 2D layered materials.

Summary: This research demonstrates that the formation of polymers hosting sp carbon chains using anthracene-based precursor molecules on Au(111) is affected by steric hindrance between aromatic groups. Through scanning tunneling microscopy experiments and density functional theory simulations, it is found that the de-metalation of organometallic structures leads to a lateral separation of adjacent polymers, preventing the formation of ordered domains.
