Abstract Sliding ferroelectricity (SFE) found in two-dimensional (2D) van der Waals (vdW) materials, such as BN and transition-metal dichalcogenides bilayers, opens an avenue for 2D ferroelectric materials. Multiferroic coupling SFE materials brings us alternative concept spintronic memory devices. In this study, using first-principles calculations, we demonstrate that MnSe multilayers constructed by the recently-synthesized monolayer have large sliding-driven reversible out-of-plane...

Nanomaterials with enzyme-mimicking functions, termed nanozymes, offer attractive opportunities for biocatalysis and biomedicine. However, manipulating nanozyme selectivity poses an insurmountable hurdle. Here, we propose the concept of energy-governed electron lock that controls transfer between substrates to achieve manipulation enzyme-like catalysis. An can be constructed opened, via modulating nanozyme's energy match barrier enzymatic reactions. iron-doped carbon dot (FeCD)...

Modeling and formulation of a delayed cyber-physical power system (DCPPS) are the basis small-signal stability analysis control synthesis system. First, logic describing interconnections between various systems differential algebraic equations (DDAEs) (DDEs) is established. It clearly shows transformation most general DDAEs non-index-1 Hessenberg form to widely used DDEs with finite terms actual delays. Second, DDAE model index-1 formulated in detail for DCPPS, which features preserving...

Aplastic anemia (AA) is a life-threatening hematologic disease with limited therapeutic options. Stalled erythropoiesis and oxidative stress-induced hemocyte apoptosis are the main pathological features of AA, yet agents that address these issues remain elusive. In this study, we report distinctive donkey-hide gelatin-derived carbon dots (G-CDs) enable activation stress elimination to tackle refractory AA. We demonstrate G-CDs can promote proliferation erythroid differentiation hematopoietic...

The construction of highly active non-precious-metal electrocatalysts is the key to achieving an efficient hydrogen evolution reaction (HER). In this paper, a N-doped carbon layer composite was successfully synthesized by self-limiting domain thermal reduction strategy, in which embedded with Ni/VN heterogeneous nanoparticles and Ni metal nanoclusters as well anchored many single atoms (denoted Ni/VN/Ni-NC). optimized Ni/VN/Ni-NC provides abundance sites high conductivity facilitate charge...

The impact of gas hydrate dissociation on submarine landslides has become an increasingly significant issue. However, previous models cannot interpret the newly discovered non-conformity between slide surface and base stability zone. Here, authors design experimental approach for visualising fluid migration during at atmospheric pressure. results identify lateral vertical pathways. Weak layers propagate nearly laterally beyond zone, which lengthens potential surface. Vertical pathways branch...

Dissipation tests after piezocone penetration are used widely to estimate the consolidation behaviour of cohesive soils. Interpretation dissipation is complicated in intermediate soils, such as silts and silty clays, since accumulated pore pressures subsequent response affected by partially drained conditions. The influence partial drainage on investigated using a large-deformation finite-element approach within framework effective stress analysis. numerical validated comparison with...

The pump-driven two-phase loop is a promising thermal management technology for avionics, but its dynamic characteristics and control strategy are not clear. A prototype of with single/dual evaporator cooling avionics was developed characteristic under different heat loads flow rates were studied. It found that after the outlet reached saturation, increasing rate would instead reduce performance, due to resistance gas tube pump power consumption. Based on this, controlling vapor quality at...

Neighbor discovery and the power of sensors play an important role in formation Wireless Sensor Networks (WSNs) mobile networks. Many asynchronous protocols based on wake-up time scheduling have been proposed to enable neighbor among neighboring nodes for energy saving, especially difficulty clock synchronization. However, existing researches are divided two parts with neighbor-discovery methods, one is quorum-based other co-primality protocols. Their distinction arrangements slots, former...
