Zwitterion-based materials by virtue of their special physical and chemical characteristics have attracted researchers to utilize them for fabricating functional coatings. The simultaneous presence of positive and negative charges renders the zwitterion-based materials with electrostatically induced hydration properties, which enables a high resistance towards oily pollutants, nonspecific protein adsorption, bacterial adhesion and biofilm formation. This review starts from the working mechanism of zwitterions and covers the fabrication strategies of zwitterion-based functional coatings, namely the zwitterion-bearing binder route, the zwitterion-bearing additive route and the post-generation of coatings containing zwitterionic precursors. The applications of zwitterion-based functional coatings are discussed, including medical implants, marine antifouling and oil-resistant coatings, with focus on the relevant mechanisms of the zwitterion-containing coatings for a specific performance. Finally, some comments and perspectives on the current situation and future development of zwitterion-based functional coatings are given.

This study investigates the structure, microstructure, and transport properties of off-stoichiometric GeTe (off-GeTe). In a narrow range of 50–53 at% Te, both the rhombohedral a-GeTe and orthorhombic g-GeTe phases coexist. Despite their similar chemical composition, GeTe and off-GeTe alloys exhibit distinct microstructural and thermal/electronic properties. Theoretical density functional theory (DFT) calculations were employed to verify that changes in the Ge/Te ratios influence the concentration of Ge vacancies, leading to a significant alteration in transport properties despite minor variations in chemical compositions. The off-GeTe alloy, which is free of Ge precipitates, displays defective domain boundaries, showcasing a non-typical herringbone nanostructure that is unprecedented for GeTe-based materials. Notably, the phase transition temperature of off-GeTe, at 620K, differs from its peak zT temperature of 698K. Moreover, a TE device incorporating off-GeTe demonstrates superior interfacial stability and higher energy conversion efficiency compared to its stoichiometric GeTe counterpart. Consequently, off-GeTe demonstrates superior TE performance and enhanced interfacial stability compared to stoichiometric GeTe. The addition of Sb to off-GeTe further improves its potential for TE applications by lifting the single-leg conversion efficiency greater than 3%. © 2024 Acta Materialia Inc.

The mechanical properties of lithium-ion batteries (LIB) are closely related to their state-of-charge (SOC) and state-of-health (SOH). Here, we introduce an in-operando acoustic technique based on acoustic impedance spectroscopy (AIS) which probes the mechanical changes that occur in the LIB during operation. Using thin, inexpensive piezoelectric resonators and widely available impedance analyzers, we can identify the acoustic resonances of commercial LIBs by measuring the complex electrical impedance of the resonator. In-operando AIS shows that these resonances are dependent on the bulk mechanical properties of the LIB, which change reversibly as the cell is cycled. We show that this technique can provide substantial information on both the SOC and SOH of a commercial LIB.

MgO has long been utilized as a catalyst/support with Lewis base properties in the chemical industry, but its synthesis with exposed (111) surfaces has received relatively little attention compared to those of (110) and (100) surfaces. The unique adsorption energy of this surface for adsorbates also remains elusive. Herein, we present a simple and scalable method for the production of MgO nanosheets exposing the (111) surface (denoted as MgO(111) NSs). This is achieved through the topotactic conversion of Mg(OH)2 NSs at elevated temperatures in an air environment. By adjusting the precursor ratio and the strength of the base, we successfully prepared Mg(OH)2 NSs consisting of approximately 6 atomic layers with lateral sizes ranging from 80 nm to 1 μm in a single step. Subsequent thermal dehydration yields MgO(111) NSs with a preserved dimension. Using Ru as the adsorbate, we found that the remarkable stability and uniformity of its atomic dispersion on the (111) surface can be attributed to the strong structural coordination provided by three oxygen atoms. In contrast, the metal-support interaction on the (110) and (100) surfaces proved to be insufficient to overcome the cohesive energy between Ru atoms, resulting in the formation of Ru clusters. Beyond Ru, this study holds great potential in guiding the rational selection of surfaces to achieve a uniform atomic dispersion of other elements. © 2024 American chemical Society.

We developed a molybdenum (Mo)-doped cobalt (Co)-heterostructure embedded on a phosphorous (P) and nitrogen (N) dual-doped porous carbon which exhibits an intrinsic electronic transport channel of Co to Mo and P. The P,Mo,O−Co/PNC/NF (NF=Nickel foam) electrode offers 335 mV overpotential at 10 mA cm−2 in OER as compared with PMA-ZIF67-NC/NF and ZIF67-NC/NF electrode with an overpotential of 357 and 373 mV respectively. Linear sweep voltammetry (LSV) of overall water splitting (OWS) supports that the current density gradually increased at a cell potential of 1.6 V with a maximum of 40 mA with a corresponding cell potential of 1.79 V at a current density of 10 mA cm−2. Density functional theory (DFT) calculations for water adsorption on optimized [111] surface of Co, CoMo, and CoMoP2 with adsorbed H2O and corresponding lattice determine the electron density difference of [111] surface with adsorbed H2O for Eads (eV) 4.23 corresponds to adsorption energy for CoMoP2. XANE-EXAFS spectroscopy of P,Mo,O−Co/PNC at Co K edge and Mo K edge suggests the presence of higher valence of both Cox+ and Mox+ without metallic Co and Mo and Co−P and Mo−P bonds as major structural units due to phosphidation as determined by R-space FT-EXAFS spectra. © 2024 Wiley-VCH GmbH.

Growing demands for precise current measurements, such as atto-ampere-level measurement of cross-cellular biological current transduction, have spotlighted a pressing need for low-noise resistors with ultra-high resistance immune to voltage fluctuations. Traditional semi-insulating materials, however, struggle to provide consistent resistance across varying voltages. To bridge this gap, we introduce a design that integrates semi-insulating 4H-SiC with atomic-level metal oxide interlayers and electrodes. The strategic adjustment of surface states via atomic-scale metal oxide layers optimizes the work functions on 4H-SiC surfaces, validated through density functional theory simulations. This design transcends conventional limitations, establishing an ideal Ohmic behavior and maintains Peta-Ohm-level resistance, unaffected by voltage variations. These on-chip devices with fine-tuned resistance are compatible with integrated circuit manufacturing processes, making them ideally suited for applications in precision electronics. © 2024, CC BY-NC-ND.
