Silk sericin (SS) is a natural water-soluble protein with the potential to chelate metal ions via its polar groups. However, difficulty of identifying saturation SS limits application as filter films. One solution construct films an indicator reflect degree silk sericin. Hence, nanocoating consisting co-assembled and anthocyanin (C3G) nanoparticles designed, constructed, characterized saturation-visualization detection behavior. Here, Zn2+ Al3+ are chosen models explore chelating ability...

In view of the wide range applications for ultra-sharp silicon (Si) nanocones, extensive research has been conducted on their fabrication processes. However, these conventional methods pose challenges in terms achieving uniformity, controllability, and cost-efficiency. This study presents a novel approach to fabricating Si nanocone structures through reactive ion etching (RIE) using tapered dioxide mask, followed by thermal oxidation sharpening reduce apex diameter 4 nm. Here SiO2 mask with...

Wind turbines with direct-driven permanent magnet synchronous generators (PMSGs) are widely used in wind power generation. According to the dynamic characteristics of PMSGs, an impact analysis PMSG-based penetration on transient stability multi-machine systems is carried out this paper based theory extended equal area criterion (EEAC). Considering most severe PMSG integration situation, changes system’s equivalent power-angle relationships after integrating PMSGs studied detail. The...

Abstract. Optimum management of irrigated crops in regions with shallow saline groundwater requires a careful balance between application irrigation water and upward movement salinity from the groundwater. Few field-validated surrogate models are available to aid under conditions. The objective this research is develop model that can using minimum input data field validated. In paper 2-year experiment was carried out Hetao district Inner Mongolia, China, physically based integrated for arid...

Abstract. Rapid population growth is increasing pressure on the world water resources. Agriculture will require crops to be grown with less water. This especially case for closed Yellow River basin, necessitating a better understanding of fate irrigation in soil. In this paper, we report field experiment and develop physically based model shallow groundwater Hetao district Inner Mongolia, arid middle reaches River. Unlike other approaches, recognizes that capacity reached when matric...

In this paper, we reported a CMOS compatible micro-Pirani gauge using the fabrication process. For first time, revealed that tiny fluid conduction gap can not only enhance sensitivity of device but also improve dynamic measurement range, especially in high-pressure region making it possible to exceed 1 atm monitoring domain. Firstly, CFD simulation was conducted simulate performance devices with (T) and large (L) validate proposed discoveries. Then, CMOS-compatible method created an overall...

Data dissemination is an important application in vehicular networks. We observe that messages networks are usually subject to both time and space constraints, therefore should be disseminated during a specified duration within specific coverage. Since vehicles moving out of region, dis-semination message repeated achieve reliability. However, the reliable for some might at cost unreliable or even no chance other messages, which raises tradeoffs between reliability fairness. In this paper,...
