Ultrathin branched PtFe and PtRuFe nanodendrites are obtained through a kinetic-controlled synthetic process. The high electrocatalytic activity can be attributed to its ultrathin branches, open porous but interconnected structure synergetic effect of multicomponents.
This work focuses on an unmanned aerial vehicle (UAV)-enabled mobile edge computing (MEC) system based device-to-device (D2D) communication. In this system, the UAV exhibits caching, and relaying capabilities to periodically provide specific service cellular users D2D receiver nodes in appointed time slot. Besides, transmitter can additional caching services reduce pressure of UAV. Note that communication between multi-type is mutually restricted different links share spectrum resources. To...
In these years, Unmanned Aerial Vehicle (UAV) is widely employed as a flying server into the Mobile Edge Computing (MEC) network to carry stochastic computation task offloaded from mobile users. However, currently, much efforts are made on individual capability of each UAV during offloading task, while neglecting coordination advantage multiple UAVs in fleeted way, leading low efficiency computing massive bursty data. this work, therefore, we propose twofold mechanism collaborative way for...
Callose plays an important role in plant development and response to a wide range of biotic abiotic stresses. However, the systematic identification callose synthase (CalS), major enzyme for biosynthesis, has been delayed crops, especially Solanaceae. In current research, 18 CalS genes (NtCalS1–NtCalS18) were identified Nicotiana tabacum classified into four subfamilies. A comprehensive analysis their physicochemical properties, gene structure, evolutionary history highlighted conservation....
Abstract Advanced oxidation processes (AOPs) have been regarded as the most promising technology for organic pollutant degradation and industrial wastewater treatment. However, lack of heterogeneous catalysts with both high activity stability long hindered development AOPs.

In this paper, therefore, we propose queue-aware cooperatively...
Abstract Self‐assembly of gold nanoparticles into one‐dimensional (1D) nanostructures with finite primary units was achieved by introducing a thin salt (NaCl) solution layer density gradient before centrifugation. The electrostatic interactions between Au would be affected and cause 1D assembly upon passing through the layer. A negatively charged polymer such as poly(acrylic acid) used an encapsulation/stabilization to help formation assemblies, which were subsequently sorted according unit...
Wireless Sensor Networks (WSNs) are one of the most commonly used network technologies and security sensing data in WSNs has attracted much attentions.
