Summary: Solution-processed few-layer graphene flakes are used as friction modifiers to achieve low friction and wear at technologically relevant interfaces. Superlubricity has been observed on nanoscale contacts lubricated by individual graphene flakes, but it is unclear if it persists on larger and morphologically disordered contacts. In this study, the friction performance of solution-processed graphene flakes is investigated using colloidal probe atomic force microscopy. The results show that wet-transferred flakes result in an inhomogeneous coating, and different friction dynamics are observed for different material substrates. Numerical simulations confirm the experimental findings and support the use of wet-transferred liquid-processed graphene flakes for achieving superlubricity in micro electromechanical systems.

Summary: Precisely controlled impurity doping is essential in modern semiconductor technologies, and desired properties can be achieved at very low concentrations. However, in two-dimensional semiconductors, the identification and quantification of impurities are challenging due to their dilute limit and the limitations of common analytical techniques. In this study, we utilize conductive atomic force microscopy to rapidly and accurately image dilute single atomic impurities. The local conductivity is enhanced by more than 100-fold due to resonance-assisted tunneling, and the imaging is selective for minority defects. We also demonstrate the detection of subsurface impurities with single monolayer depth resolution in multilayer materials.

Summary: The electrochemical polymerization of 3,4-ethylenedioxythiophene (EDOT) was studied in the presence of an anionic copper and zinc octa(3',5'-dicarboxyphenoxy)phthalocyaninate. It was found that the presence of phthalocyaninate ions leads to a faster polymerization of EDOT compared to a low-molecular-weight electrolyte. UV-Vis-NIR and Raman spectroscopies showed that copper phthalocyaninate leads to a higher content in the resulting PEDOT composite films, and a 1:2 EDOT-to-carboxylate group ratio was determined to be optimal for a higher phthalocyaninate content in the film.

Summary: The photochromic performance of PLD-grown nanostructured MoO3 thin film was studied, showing a shift in Raman peak frequency with increasing LASER power due to coloration process. The Raman spectra characterized strong peaks at 819 and 994 cm-1, attributed to O-Mo6+-O and Mo6+-O bonds vibrations respectively, with the peak at 994 cm-1 associated with terminal oxygen stretching mode for orthorhombic MoO3. This study also revealed enhanced photochromic response of MoO3 nanostructures under LASER excitation, demonstrating a transition from Mo6+ to Mo5+ states and subsequent coloration.

Summary: In this study, a metal-organic framework (MOF) named TMU-5 was used to synthesize the KNbO3@TMU-5 hybrid material, which exhibited higher ammonia production rate under UV light irradiation compared to pure KNbO3. Various characterization techniques revealed that the improved photoactivity of KNbO3@TMU-5 was attributed to its larger surface area, higher electron-hole separation efficiency, and higher density of negative charges on Nb sites.

Summary: In recent years, there has been a significant increase in the number of studies focusing on the synthesis and characterization of deep eutectic solvents (DESs). DESs, known for their stability, ease of synthesis, and ability to tailor properties, are considered one of the greenest solvent families used in various fields such as organic synthesis, catalysis, electrochemistry, and medicine. However, there is a lack of research on specific groups of DESs, particularly those comprising organic acids (OA-DESs), despite their potential in biomedical applications. This review aims to highlight the importance and applications of OA-DESs as antimicrobial agents and drug delivery enhancers, providing valuable insights for future developments in this field.

Summary: The hydrogen and oxygen evolution reactions (HER and OER) are crucial steps in electrochemical water splitting. Efficient electrocatalysts for both reactions under alkaline conditions are still a challenge. Currently, nitrogen-doped carbon stabilized single atom Ru and RuO2 are the preferred materials for HER and OER, respectively. This study proposes a strategy for preparing Ru embedded in a carbon nitride matrix for efficient HER and OER in KOH solution, demonstrating smaller overpotentials and high catalytic stability compared to benchmark catalysts.

Summary: Potentiostatic electrodeposition was used to manufacture gold-coated AFM tips for TERS applications. The growth of the gold film was initiated by instantaneous nucleation on the doped-silicon tip surface. This cost-effective method allowed the production of robust AFM-TERS probes with localized surface plasmon resonances, achieving a yield of 53%. These probes enable TERS mapping of graphene oxide flakes and carbon nanotubes with lateral resolution below 20 nm, independent of the curvature radius of the metallized tip apex.

Summary: Paracellular permeability is regulated by tight junctions, which not only restrict the diffusion of ions and hydrophilic molecules, but also play important roles in cell polarization and protein localization. New understanding of tight junction components has challenged the traditional concept of diffusion barriers.

Summary: The complexes of He, Ne, Ar, Kr, and Xe with B3N3H6 were investigated using MP2, CCSD(T), and SAPT ab initio methods. The complexes can be described as mono-, di-, and tri-coordinated to the N atoms, with stability following the order N-mono < N-di < N-tri. The interactions are dominated by dispersion and the binding energies are within the range of 1 or 2 kcal mol(-1). The results were compared with a recent DFT study on larger BN sheets complexes [Phys. Chem. Chem. Phys. 24 (2022) 2554-2566.].

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.

Experimental data shows that CsPbI3 nanorods have an extremely high two-photon absorption cross-section, significantly surpassing organic chromophores and other CsPbBr3 nanocrystals. Moreover, adjusting the aspect ratio can significantly enhance the absorption ability. Additionally, the study also reveals a moderate quantum confinement effect on the single-photon and two-photon absorption cross-section of the nanorods.
