Summary: Anode-free lithium batteries with high-initial-efficiency, long-cycle-life, and long-calendar-life have been achieved by using an organic Li salt monolayer bonded on Cu. The functional salt results in the formation of a LiF-rich interphase on Cu and guides Li nucleation and growth, reducing Li loss and suppressing galvanic Li corrosion and Li-electrolyte reactions. The activated cell retains 95.2% capacity after 600 cycles and shows no performance damage during calendar aging.

Summary: One of the most appealing aspects of 2D transition-metal dichalcogenides (2D-TMDs) is their diverse crystal types and the ability to generate heterostructures with distinctive features. In this study, the structural and electronic properties of H-phase MoTe2 monolayer, T'-phase WTe2 monolayer, and their in-plane heterostructures (H-MoTe2/T'-WTe2) were explored using first-principles calculations. The band structures of these heterostructures were strongly influenced by the relative orientations of the monolayers at the interface. Some of the in-plane heterostructures exhibited effective Schottky barrier heights suitable for constructing field effect transistors (FETs). These findings provide insights for the design of high-performance electronic and optoelectronic devices.

Summary: The diffusion phenomenon in the Ti-Ni binary system was studied at 1173 K. Analysis of microstructure and texture revealed the presence of three stable intermetallic compounds and two metastable intermetallic compounds at the interface. The formation of Ti2Ni was found to be the first compound to form at the Ti-Ni diffusion interface. The integrated diffusion coefficients for Ti2Ni, TiNi, and TiNi3 phases were calculated to be 3.53 x 10(-12), 18.1 x 10(-15), and 6.2 x 10(-15) m(2)/s, respectively, using the Wagner method at a temperature of 1173 K.

Summary: The new two-dimensional black arsenic-phosphorus (ML b-AsP) alloy has attracted significant attention in nanoelectronic devices due to its strong structural stability, ultra-high carrier mobility, and controllable direct band gap of semiconductors. Through first-principles calculations and quantum transport simulations, the interfacial electrical properties and transport properties of ML b-AsP alloy in contact with various metal substrates have been systematically investigated. The results show that the alloy forms weak Schottky contacts with all metal interfaces, except for Pt, and the FET configuration with a Pt electrode displays superior electrical transport performance.

Summary: In aqueous lithium-ion batteries, the distortion of the local structure of the positive electrode material can reduce cell performance, and the absence of a protective layer can accelerate capacity fading. A lithiated Nafion layer coating on the electrode can delay capacity fading by limiting water movement, indicating the need for a tolerant ion channel to control water inflow.

Summary: This study investigated the microstructural changes and mechanical properties of Sn-Cu solders with Al(Si) addition after multiple reflows to evaluate their reliability under high heat and strong vibrations. It was found that the Sn-0.03Al(Si) solder exhibited the least growth of intermetallic compounds after reflows, with Al-Cu and Cu-Al-Sn IMCs present inside the solders in increasing amounts with higher Al(Si) content. The Sn-0.5Cu-0.03Al(Si) solder showed the highest shear strength and ductile fracturing in all three solders, indicating its potential application in automotive electronic components.

Summary: Heterogeneous integration of monolayers is an effective approach to combine materials with available platforms for unprecedented properties. The challenge lies in manipulating interfacial configurations in stacking architecture. This study focuses on the interfacial traps of monolayer MoS2 and illustrates a mechanism for the onset of saturation photocurrent and the reset behavior in the monolayer photodetector. The response time for photocurrent can be significantly reduced through electrostatic passivation of interfacial traps, paving the way for fast-speed and ultrahigh gain devices of stacked two-dimensional monolayers.

Summary: Solvent-free reduction of CO2 using amorphous TiOx with embedded colloidal perovskite nanocrystals (PNCs) has been achieved by carrying out hydrolysis of titanium butoxide (TBOT) on the PNC surface. The photoexcited electrons are transferred from PNCs to TBOT, enabling photocatalytic reactions using TiOx under visible-light excitation. Efficient visible-light-driven photocatalytic reactions at PNC/TiOx interfaces, with a CO production rate of 30.43 µmol g(-1) h(-1) and accelerated degradation of organic pollutants under natural sunlight, have been demonstrated.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
