ABSTRACT Nitrogen deposition can alter the interactions between litter types during their decomposition, and thus affect material cycling ecosystem stability. However, it is unclear how differences in initial chemical properties of mixtures response to nitrogen deposition. In this study, we investigated three mixtures: high quality–high quality ( Robinia pseudoacacia – Stipa grandis , Rp‐Sg, mixed form F1), quality–low (Rp– Setaria viridis Rp‐Sv, F2), low Artemisia gmelinii –Sv, Ag‐Sv, F3)....
ABSTRACT Graphene nanosheets‐filled epoxy composites (GNS/Epoxy) were prepared at different filler loading levels from 0.25 to 3.00 wt %. A fast dispersion method as short 5 min is employed disperse GNS in matrix, which was enough for the homogeneous of with help high ultrasonic frequency 100 kHz and power 200 W heat treatment temperature 70 °C. The maximum electrical conductivity thermal achieved 0.058 S m −1 0.57 K , respectively, a low percolation threshold 1.50 conductivities further...
Wind power systems participating in primary frequency regulation have become a novel trend. In order to solve the problem of over-speed deloading (OSD) control wind failing provide reserved capacity for while under turbulent winds, this paper analyzes influence mechanism turbulence characteristics on OSD and relationship between reserve coefficient speeds, also quantifying characteristic index coefficient. The range is obtained accordingly, based which improved proposed dynamically optimize...

Thermal interface material (TIM) is crucial for heat transfer from a source to sink. A high-performance thermal with solid–solid phase change properties was prepared improve both conductivity and interfacial wettability by using reduced graphene oxide (rGO)-coated polyurethane (PU) foam as filler, segmented (SPU) matrix. The rGO-coated (rGOF) fabricated self-assembling method the SPU synthesized an in situ polymerization method. pure rGOF/SPU composite exhibited obvious proper temperature,...
Polylactic acid (PLA)/poly(ε-caprolactone) (PCL) blends have exhibited good shape memory properties and degradable characteristics in various 4D printing fields such as biomedicine, flexible electronics, soft robotics, where the service temperature fluctuates easily by environment polymer characteristics. In this work, printed PLA/PCL samples with different infill densities were prepared material extrusion of pre-extruded filaments characterized under temperatures. The results show that...
Abstract The viscoelastic properties of the epoxy surface have been investigated by nanodynamic mechanical analysis (nano‐DMA). Both a Berkovich tip and conospherical were used under condition different forces (i.e., penetration depths) in frequency range 10–200 Hz. Loss tangent storage modulus are characteristics that describe properties. effect force frequency, depth, shape on is studied discussed according to features microstructures mobility molecular chains. experimental results show...
With the rapid development of power grid, high penetration new energy sources and diversity loads have further aggravated uncertainty "source-load", which has brought huge challenges to peak shaving grid. In order ensure reliable operation system during electricity peak, this paper combines IoT technology propose a flexible control strategy for controllable large industrial that considers interrupt priority. Firstly, perception fusion framework load information is constructed based on...
Selenium materials are widely used in photoelectrical devices, owing to their unique semiconductive properties. Single‐crystal selenium nanobelts with large specific surface area, fine photoconductivity, and biocompatibility provide potential applications biomedical nanodevices, such as implantable artificial retina rapid photon detector/stimulator for optogenetics. Here, we present a nanobelt based nanodevice, which is fabricated single Se nanobelt. This device shows photo response,...
The wireless charging system (WCS) is widely employed to solve the problem of underwater autonomous vehicles (AUVs). However, AUV prone misalignment caused by tidal currents, which directly leads fluctuations in transmission efficiency and output power. For this reason, a circular-arc-type (CA-type) magnetic coupler with strong tolerance was proposed article. Compared ring-type coupler, had better field convergence lower weight. Further, effect dimensional parameters on CA-type performance...
