Summary: Zinc-based batteries have gained attention for their cost-effectiveness and safety, but suffer from poor interface stability between the zinc anode and the electrolyte. This review systematically discusses the relationship between interface properties, solvation sheath structure, and the components of the Helmholtz layer, highlighting the possible transport pathway of zinc ions and the structural evolution mechanism of the electrical double layer (EDL) at the interface. The scientific principles for EDL regulation are proposed to inspire future electrolyte and interface design.

Summary: The dynamic behaviors of double emulsion droplets flowing through a Y-shaped bifurcation were experimentally investigated, focusing on the influences of droplet length, droplet velocity, and liquid viscosity. Flow patterns were categorized based on typical features of motion, including the number of interfacial breakups and the coupling effect between interfaces. The critical conditions for the coupling effect were determined using the relative difference in residence time of inner and outer droplets. The impact of droplet length and velocity on flow pattern transitions was summarized, and the corresponding dynamic mechanisms were discussed based on interfacial deformations.

Summary: The experimental investigation focused on the build-up of small coating layers from deposited droplets dried under forced convection. The evolution from single droplet residue to multi-deposit coating layer, as well as the development of porosity during incremental layer formation, were analyzed. The study compared three model substances representing nano-and microsuspensions, as well as solutions, and investigated the morphologies, porosities, and characteristic phenomena of resulting layers obtained via sessile droplet drying on a flat, partially wetting substrate.

Summary: A composite layer consisting of a lithophilic layer and a LiF-rich solid-electrolyte interphase (SEI) layer is achieved on a Cu foam current collector through thin film deposition coating and in-situ fluoridation. This well-designed 3D current collector enables dendrite-free Li deposition behavior and exhibits high coulombic efficiency, stable Li plating/stripping behavior, and remarkable cycling stability/rate performance in both coin-type and pouch full cells.

Summary: We investigated the formation of a 2D wetting layer during quantum dot growth using the droplet epitaxy technique. By combining photoluminescence excitation spectroscopy, lifetime measurements, and transmission electron microscopy, we identified the presence of an InGaAs wetting layer in these quantum dots, even without distinguishable wetting layer luminescence. We observed that increasing the amount of Ga deposited on a GaAs (100) surface prior to the growth of InGaAs quantum dots significantly reduced the emission wavelength of the wetting layer, making it indistinguishable from the GaAs acceptor peak emission. However, increasing the amount of Ga deposited did not suppress the formation of a wetting layer under the growth conditions used here.

Summary: Constructing a reliable solid-electrolyte interphase (SEI) plays a vital role in achieving highly reversible zinc metal (Zn-0) electrodes. Instead of the traditional bulk solvation mechanism, this study reveals that the structure of SEI is mainly influenced by electric double layer (EDL) adsorption. By manipulating the EDL adsorption and Zn2+ solvation using ether additives, a layer-structured SEI with high rigidity and toughness is formed, leading to improved performance of the zinc metal electrodes.

Summary: In an electron double-slit experiment, interference fringes composed of dot images were controlled using two electron biprisms. Interference features of electron waves were observed under different conditions, and it was concluded that interference fringes can only be observed when the path information of individual electrons is not available.

Summary: The study combines experiments and simulations to provide a molecular picture of double-layer formation under applied voltage, showing the stripping away of cation/anion hydration shells for an NaCl electrolyte at the Au surface at varying bias potentials. Results indicate that Na+ is attracted towards the electrode at the smallest negative potentials, while stripping of the Cl- hydration shell occurs only at higher potential values. The phenomena are measured directly by THz spectroscopy using ultrabright synchrotron light and rationalized by molecular dynamics simulations and electronic-structure calculations.

Summary: This study reports the current-voltage characteristics of La0.5Gd0.2Ca0.3MnO3 (LGCMO) manganite thin films grown by pulsed laser deposition on Nb:SrTiO3 substrates, irradiated with swift heavy ions. Measurements such as X-ray diffraction and atomic force microscopy were performed to understand structural behaviors, while current-voltage data was collected to analyze lattice strain, grain size, and grain boundary density effects. Additionally, the impact of annealing on ZnO/LGCMO interfaces was studied, discussing modifications induced by annihilation, structural strain, and surface morphology.

Summary: Low-energy off-normal Ar+ ion irradiation on Si (100) surface leads to triangular features with nano-scale ripple patterns, showing stronger lateral dependency on angle of incidence. Simulations incorporating dispersion term reproduce experimentally observed triangular features, with tuning of parameters generating angle and fluence effects similar to experiments. Both experiment and simulation confirm more triangular elevations than depressions, with their number increasing with incidence angle up to 67 degrees.

Summary: The spatial variation of the nanoplasmonic behavior of Ag decorated TiO2 film structure was achieved by using a novel collimated glancing angle deposition technique (collimated-GLAD) to prepare a tailored optical response of the underlying dielectric TiO2 thin film. The blue shift in maximum attenuation coefficient region and minimum film transmittance region of the Ag/collimated-GLAD TiO2 nanocomposite coating with increase in height from the evaporation source was due to the localized surface plasmon resonance (LSPR) phenomenon and thin film interference. The measured transmittance spectra showed spatial selectivity in LSPR wavelength, and the variation of the refractive index of the surrounding TiO2 layer was the key factor responsible for the spatially varying nanoplasmonic response. The Ag/collimated-GLAD TiO2 film exhibited enhanced Raman scattering and photocatalysis driven dimerization conversion, resulting in the substantial enhancement of Raman peak intensities compared to the blank substrate.

Summary: Strontium oxide (SrO) loaded borosilicate glass-ceramics were synthesized and the effect of loading on the phase and chemical durability of the matrix was investigated. The samples with increasing content of SrO showed a more pronounced ceramic phase, and Sr element was distributed homogeneously throughout the matrix. The normalized leaching rates of Si, B, Ba, Ca, Sr, and Ti were obtained after 30 days with 25 mol% SrO loading, suggesting that glass-ceramic wasteforms with a perovskite phase are advantageous for immobilizing short-lived radionuclides such as Sr.

Summary: This study proposes a technique to improve the interfacial adhesion of graphene membrane to a periodically trenched PDMS substrate by suppressing the mechanical folding instabilities in a prestretch-release process. The conformal wrinkling of the graphene membrane is confirmed through AFM imaging, which results from its pinning into the trenches. The impact of the substrate's topography on the buckling behavior of the graphene membrane is shown by surface-engineering of the PDMS substrate using ion beam irradiation.

Summary: The effect of oxygen plasma processing on the wettability of PTFE surfaces was studied. By adjusting the RF power and treatment time, the surface of PTFE was transformed from hydrophobic to superhydrophobic. Atomic force microscopy revealed that surface roughness played a key role in the changes in wettability. XPS and FTIR analysis showed no significant chemical alteration on the treated PTFE surfaces.
