Summary: The hydrophobicity found in rare-earth oxides is intriguing. Despite its hydrophilic nature, the CeO2 (100) surface exhibits hydrophobic behavior when immersed in water. A detailed analysis of the water structure and dynamics reveals that the first water layer in contact with the hydroxylated CeO2 surface acts as a hydrophobic interface. This discovery introduces a new concept of hydrophobicity mediated by specific water patterns on a hydrophilic surface in water/rare-earth oxide interfaces.

Summary: Two isostructural calcium-phosphonate monoester layered coordination polymers grafted with methoxyethyl (Ca-L1) and ethyl (Ca-L2) groups were synthesized using a solvothermal method. Both materials can be exfoliated into metal-organic layers (MOLs) with structure retention via a top-down approach. The introduction of phosphonate monoester (PME) grafting groups plays a crucial role in regulating the hydrophilicity-hydrophobicity and water stability of the materials.

Summary: This study investigates the dynamics of droplets impacting hybrid surfaces with varying wettabilities using a two-phase finite volume method. It is found that the maximum spreading factor for both Newtonian and non-Newtonian droplets is larger on surfaces with linear wettabilities, but minimal on stepwise wetting surfaces. The residence time of Newtonian droplets is longest on surfaces with a linear wettability distribution from hydrophilic to superhydrophobic, while for non-Newtonian droplets, it is longest on stepwise hydrophilic to superhydrophobic surfaces.

Summary: Water-soluble nonionic surfactant, C12E5, was found to spontaneously bloom to the surface of hydrophobic polyisoprenes, generating hydrophilic surfaces. The depth profiles were quantified using neutron reflectometry (NR) and the surface properties were characterized using contact angle analysis and atomic force microscopy (AFM). Despite resistance to dissolution, water exposure altered the wettability of the surface, revealing two distinct populations of surfactant on the polyisoprene film surface, with one population being laterally inhomogeneous.

Summary: The insertion of a metal layer between an active electrode and a switching layer leads to the formation of a ternary oxide at the interface. The properties of this self-formed oxide are dependent on the Gibbs free energy of oxide formation of the metal (Delta G degrees(f)). The role of various ternary oxides in the switching behavior of conductive bridge random access memory (CBRAM) devices was investigated. The ternary oxide acts as a barrier layer that limits the mobility of metal cations in the cell, promoting stable switching. Choosing a metal layer with an appropriate Delta G degrees(f) is crucial for achieving reliable CBRAM devices.

Summary: This paper proposes a memristor-assisted sign-based background calibration scheme for analog-to-digital converters (ADCs). The scheme was implemented and validated in a 12-bit asynchronous SAR ADC, which consists of a hybrid binary/R-2R DAC and other peripheral circuits. The proposed calibration technique uses a memristor to detect and correct DAC mismatches, and the circuit exploits the advantages of memristors such as small area and resistance switching property. Simulation results demonstrate that memristors can improve the linearity of high-resolution SAR ADCs.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
