Summary: The evaporation mechanism of nanodroplets is different from that of macroscopic water droplets. Regardless of hydrophobicity, the evaporation rate of nanodroplets does not follow the traditional mode and their evaporation behavior is characterized by non-equilibrium wetting. The vapor concentration on the surface of nanodroplets does not reach a steady state. The evaporative lifetime of nanodroplets is directly related to the hydrophobicity of the substrate.

Summary: The reduction kinetics of zinc ferrite in CO atmosphere follows a step-wise mechanism influenced by reaction rate and diffusion, with higher CO concentrations accelerating the reduction process. The reduction is controlled by the rate of the first or second order in different CO conditions, with diffusion being the rate-determining step in the second stage.

Summary: Friction plays a crucial role in contact pairs at different scales, but nano-sized friction behavior differs from macroscopic behavior. The study found that multi-slip phenomenon occurs during the tangential loading of a single nano-sized asperity, and existing macroscopic friction models need to be modified to accurately describe nano-sized friction. The plastic deformation mechanism and the size effect of asperities also need to be considered.

Summary: This work investigates the effect of the size of chemically preformed gold nanoparticles (seeds) on the electrochemical deposition of gold onto their surface. The growth potential and current strongly depend on the size of the seeds due to size-dependent kinetics of the growth process. The electrochemical reversibility is determined by the size of the gold nanoparticles, scan rate, metal precursor concentration, and coverage of gold nanoparticles on the surface.

Summary: The effects of CaO, reduction time, and reduction temperature on the migration mechanism and kinetic model of Zn were investigated. Results showed that CaO enhanced the volatilization rate of Zn by promoting the precipitation and enrichment of ZnO on the surface of the Fe-CaO mixture. The reduction steps of ZnFe2O4 with CaO were ZnFe2O4 -> Ca2Fe2O5 -> FeO -> Fe. The volatilization model of ZnFe2O4 reduction shifted from a first-order chemical reaction model to a three-dimensional diffusion model, with a decrease in apparent activation energy from 313.9 to 91.77 kJ/mol, providing favorable conditions for efficient zinc reduction and volatilization.

Summary: This study demonstrates that interfacial engineering, based on the creation of a CdS mediate layer between Au and CsPbBr3, is a key strategy for overcoming the suppression of plasmon resonances in Au/CsPbBr3 heteronanocrystals. The resulting Au@CdS/CsPbBr3 heteronanocrystals generate long-lived plasmon-induced charge carriers with a lifetime several orders of magnitude longer than those reported for colloidal plasmonic metal-semiconductor systems. These long-lived carriers can efficiently drive CO2 photoreduction, outperforming previously reported CsPbBr3-based photocatalysts. These findings reveal a new paradigm for harnessing the substantial energy of transient plasmons through synergistic coupling of plasmonic metals and halide perovskites.

Summary: The physical properties of materials are determined by the valence electron configurations, and different valence shells lead to different phenomena. In this study, we examined the valence electron density and orbital population of Sc2+ in the compound ScS using quantitative convergent-beam electron diffraction. Our results show that the 4s orbital is occupied by Sc2+, which is unexpected as it is usually the 3d orbital that is occupied in transition metal atoms. This finding reveals a unique electron configuration in a transition metal compound and suggests potential ways to modulate material properties by controlling electron orbitals.

Summary: In this work, the researchers used low-dose integrated differential phase-contrast scanning transmission electron microscopy (iDPC-STEM) to directly observe the oxygen shifting and polar-nonpolar phase transitions in freestanding ZrO2 thin films. They clarified bidirectional transitions between antiferroelectric and ferroelectric orders and explained the mechanism of interfacial polarization relaxation at the unit-cell scale. The polarization switching was found to be strongly correlated with Zr-O displacement and two-step tetrahedral-to-orthorhombic phase transition.

Summary: Nanomaterials, especially nanoscale motifs of binary metal sulfides, have been used in relevant energy applications as conversion materials with high theoretical capacity and low cost. This review focuses on the structure-composition-property relationships for battery applications, involving the variation of nanoscale architectures or the introduction of conductive carbon-based entities. The microwave-mediated synthetic approach is explored extensively to generate metal sulfide nanostructures and tailor them for energy storage applications by controlling both chemical composition and physical morphology.

Summary: Understanding the driving mechanisms behind metal-insulator transitions (MITs) is crucial for controlling material properties. The nature of charge order and its role in the MIT of magnetite Fe3O4 have remained unclear. Recent research has found a nematic charge order in the high-temperature structure of Fe3O4, which competes with the lattice order and triggers the Verwey transition. This discovery uncovers an unconventional type of electronic nematicity and provides insights into the mechanism of transition in Fe3O4 via electron-phonon coupling.

Summary: In this study, surface modulation was used to stabilize the Ni-rich layered cathode and improve its cycle stability and rate capability. A wet-chemistry process was developed to deposit uniform ZrO(OH)(2) nanoshells and Li2ZrO3 nanoparticles on the surface of Ni0.905Co0.095(OH)(2)(NC0.9-OH) hydroxide precursors. This surface control technique achieved an optimized balance between surface stabilization and charge transfer, resulting in exceptional capacity retention and rate capability.

Summary: Electrospinning micro-nanofibers are gaining popularity in the medical field due to their exceptional physicochemical properties and biocompatibility, making them ideal for use as microbial immobilized carriers in wastewater treatment. This study immobilized aerobic denitrifying bacteria on micro-nanofibers made from different concentrations of polyacrylonitrile (PAN) solution. The results showed that 15% PAN micro-nanofibers with a tighter surface structure were not suitable as microbial carriers, while 12% PAN micro-nanofibers demonstrated higher cell density and total protein, making them the optimal choice for aerobic denitrification.

Summary: The correlation between cationic ordering transition and OR degradation in P3-Na0.6Li0.2Mn0.8O2 is revealed through in situ structural analysis. Suppressing the in-plane cationic ordering transition can improve the OR capacity by approximately twofold. First-principles calculations show that the charge ordering and alignment of the degenerate e(g) orbital induce lattice-level collective Jahn-Teller distortion, promoting intralayer Mn-ion migration and accelerating OR degradation.

Summary: In this study, the staging structure and evolution of lithium-intercalated graphite were revealed at the nanoscale using cryogenic-transmission electron microscopy and other methods. The intercalated lithium ions were found to distribute unevenly, leading to local stress and dislocations in the graphite structure. Each staging compound exhibited macroscopic order but microscopic inhomogeneity, revealing a localized-domains structural model.
