Summary: In the field of nonintrusive load monitoring (NILM), extensive research has been done on both hardware and load disaggregation algorithms, but there is a lack of publicly available hardware design schemes for real-time load disaggregation, which increases the barrier to entry. This article presents a novel smart socket using easily accessible sensors to enable more researchers to participate in NILM quickly. It combines a time-efficient automatic state detection algorithm and a factorial hidden Markov model to achieve real-time load disaggregation, addressing the issue of requiring extra information in traditional hidden Markov model-based algorithms. Experimental results confirm the efficiency and effectiveness of the proposed smart socket.

Summary: The weldability of Ti/Cu/Fe trimetallic butt welds explosively bonded was investigated, and it was found that the welds were free from cracks and had similar phase constituents at the interfaces. Cu4Ti intermetallics were formed adjacent to the Cu alloy, while CuTi2 intermetallics showed a wide distribution with different morphology. Severe cracks were observed at the Cu/Fe interface, whereas quasi-cleavage fracture occurred at the Ti/Cu interface and intergranular fracture in the Fe weld metal.

Summary: By designing a carbon bridged metal-organic framework (MOF@CC), the dissociation kinetics of Li+-solvents is catalyzed and stimulated, leading to rapid conversion kinetics of sulfur species in lithium-sulfur batteries. The bridged MOF@CC provides a special transport channel for accelerating Li+ transport and the C-N bridge enhances electron exchange, promoting catalytic efficiency and inhibiting polysulfide aggregation. The modified separators lead to high reversible capability, capacity retention, and high-rate performance of Li/S batteries. These results demonstrate the efficiency of catalyzing desolvation for fast Li+ transport kinetics and polysulfide conversion.

Summary: This article presents a simple synthetic method to prepare tin sulfide (SnS)/carbon hybrid materials. Reduced graphene oxide (rGO) was wrapped on the surface of SnS, and SnS nanospheres were in-situ coated with pyrolytic carbon, forming a hierarchical carbon network structure. This structure enhances the electronic conductivity of SnS@C@rGO hybrid and improves its performance. The double carbon coating strategy improves the structural stability and battery performance of SnS anode materials and can be applied to modify other anode materials for sodium-and lithium-ion batteries.

Summary: This study demonstrates that the capacity fading of single-crystal Ni-rich layered cathodes at high voltage is caused by surface structure degradation. The introduction of rare earth element Sc leads to a nanoscale reconstruction layer, which alleviates kinetic barriers for lithium ions and improves the reversibility of phase transition. The Sc-doped cathodes exhibit a superb capacity retention rate and minimal capacity loss per cycle. This study provides new insights for the research of Ni-rich layered cathode materials with high energy density.

Summary: In this study, the potential of InBi as a catalyst for nitrate reduction to ammonia (NRA) was systematically studied using density functional theory calculations. The results show that InBi exhibits high activity for NRA through an O-end pathway, with the free energy evolution of all intermediates being downhill in the most favorable elementary steps. The activation of nitrate is attributed to the strong orbital hybridization between oxygen and indium atoms, resulting in enhanced charge transfer and NO3- adsorption. Moreover, the competitive hydrogen evolution reaction (HER) is effectively suppressed due to the weak adsorption of proton. This study not only confirms the great electrocatalytic potential of InBi as a novel catalyst for NRA but also suggests a new approach for the design of practical NRA electrocatalysts.

Summary: This study explored the interfacial thermal energy transport ability of graphene/hexagonal boron nitride heterostructure with different symmetric tilt grain boundaries at the interface using molecular dynamics simulations. The effects of tilt angle and interface atomic connection type on the interfacial thermal conductance were considered. The results showed that the symmetric tilt grain boundaries reduced the interfacial thermal conductance of the heterostructure by decreasing the overlap of in-plane phonon density of states of atoms near the interface. It was also observed that Model II had superior interfacial thermal energy transport ability compared to Model I, with little influence of symmetric tilt grain boundaries on the interfacial thermal conductance at large tilt angles.

Summary: Molecular dynamics simulations were used to investigate the interfacial mechanical properties of periodic wrinkled graphene (GR) with a polyethylene (PE) matrix. The study considered the influence of amplitude (H), wavelength (lambda), and vacancy defect on the interfacial mechanical properties of periodic wrinkled GR, and analyzed the potential mechanisms. The results showed that periodic wrinkled GR exhibited superior interfacial mechanical properties compared to flat GR, especially when H/l = 0.51, resulting in a 29.3% increase in interfacial strength. The radial distribution function (RDF) analysis indicated that stronger interfacial mechanical properties were associated with a greater number of PE molecular chains attached to GR when separated from the PE matrix. Additionally, the study found that vacancy defects in periodic wrinkled GR did not always degrade interfacial mechanical properties. When the vacancy defect content was 20%, the interfacial mechanical properties were improved due to reduced interfacial distance and increased interface roughness.
