Article Abstract
Sublimation drying is used in the drying process of semiconductor device manufacturing. However, the solidification behavior mechanics of sublimation agents on substrates has not been clarified. Therefore, the properties of solidified films within substrate surfaces can become nonuniform, leading to their collapse. This study aimed to analyze the interface growth behavior during the cooling and solidification of a water/ice system as a basic case and to clarify the dynamic mechanism of the solidification behavior of liquid films on Si substrates. The solidification behavior of a water/ice system on Si substrates was captured on a video at different cooling rates. The recorded video was subjected to a digital image analysis to examine the crystal morphology and quantify the interface growth rate. The least-squares method with kinetic formulas was used to evaluate the feasibility of fitting the temperature variation to the interface growth rate. A visual examination of the morphology of interfacial growth revealed that it can be classified into four morphologies. The proposed kinetic equation describes the experimental results regarding the temperature dependence of the interfacial growth rate. Through image analysis, the interface growth rate of water and ice was quantified, and an evaluation formula was proposed.

Glycosaminoglycan-based biohybrid hydrogels represent a powerful class of cell-instructive materials with proven potential in tissue engineering and regenerative medicine. Their biomedical functionality relies on a nanoscale polymer network that standard microscopy techniques cannot resolve. Here, we introduce an advanced analytical approach that integrates transmission electron microscopy, X-ray scattering, and computer simulations to directly and quantitatively characterize the nanoscale molecular network structure of these hydrogels.

In this study, we report the synthesis of single-crystalline h-BN on Ni(111) under ultrahigh vacuum (UHV) conditions using hexamethylborazine (HMB) as a nonclassical precursor. The novel use of HMB facilitates the diffusion of methyl groups into the bulk of Ni(111), playing a critical role in the achievement of high-quality crystalline h-BN layers. The synthesis is performed on a 2 mm-thick Ni(111) single crystal and on a 2-μm-thick Ni(111) thin film on sapphire to evaluate the feasibility of synthesizing h-BN on industrially relevant substrates.

Lithium metal batteries (LMBs) have emerged as the most promising candidate for next-generation high-energy-density energy storage systems. However, their practical implementation is hindered by the inability of conventional carbonate electrolytes to simultaneously stabilize the lithium metal anode and LiNiCoMnO (NCM811) cathode interfaces, particularly under extreme operating conditions. Herein, we present a transformative molecular design using 3,5-difluorophenylboronic acid neopentyl glycol ester (DNE), which uniquely integrates dual interfacial stabilization mechanisms in a single molecule.

Li-metal batteries promise ultrahigh energy density, but their application is limited by Li-dendrite growth. Theoretically, fluorine-containing anions such as bis(fluorosulfonyl)imide (FSI) in electrolytes can be reduced to form LiF-rich solid-electrolyte interphases (SEIs) with high Young's modulus and ionic conductivity that can suppress dendrites. However, the anions migrate toward the cathode during the charging process, accompanied by a decrease in the concentration of interfacial anions near the anode surface.

Hypothesis: Gas hydrate formation in sediments is influenced by the availability of gas-water interfacial areas, which governs gas-water interactions. The surface wettability of sediment particles is expected to affect the spatial distribution of water within the pore space, thereby altering the extent of gas-liquid contact. Consequently, by tuning the wettability heterogeneity of the sediment, the spatial distribution of pore water can be regulated, which in turn influences the gas-water interactions and the kinetics of gas hydrate formation.
