Title: Synthesis and Electrochemical Coating of nanostructured materials for biosensors, catalysis and Energy Storage Applications

Abstract: The existing carbon materials can be classified into activated carbon (0-dimensional), carbon nanotubes (CNT) (1-dimensional), graphene (2-dimensional) and carbon foams (3-dimensional). Among these, graphene is well known to be the top candidate; However, preparation of graphene from graphite is an intricate procedure that can lead to an explosion during the oxidation of graphite. Similarly, the preparation of CNT also has some practical difficulties due to the complicated instrument setup. Fascinatingly, the preparation of ACs is simple, environmentally friendly and cost-effective. For the first time, Pongam seed shells-derived activated carbon and cobalt oxide (~2-6 nm) nanocomposite (PSAC/Co3O4) is prepared for the high performance non-enzymatic glucose sensor and supercapacitors. Remarkably, the fabricated glucose sensor is found to be exhibit an ultra-high sensitivity with a lower detection limit, and long-term durability. Moreover, the PSAC/Co3O4 electrode possess an appreciable specific capacitance and long-term cycle stability. The high surface area carbon porous materials (CPMs) synthesized by the direct template method via self-assembly of polymerized phloroglucinol-formaldehyde resol around a triblock copolymer template were used as supports for nickel nanoparticles (Ni NPs). Further electrochemical measurements by cyclic voltammetry (CV) and differential pulse voltammetry (DPV) also revealed that the Ni/CPM modified electrodes showed excellent sensitivity (59.6 µA µM-1 cm-2) and relatively low detection limit (2.1 nM) toward the detection of Hg(II) ion. The system is also been successfully applied for detection of mercuric ion in real sea fish samples. Furthermore, a facile method has been developed for fabricating selective and sensitive electrochemical sensor for the detection of toxic metal ions, which invokes incorporation of palladium nanoparticles (ca. 3-4 nm) on fruit peels-derived porous activated carbons (PACs). The Pd/PAC-modified GCEs were exploited as electrochemical sensors for the detection of toxic heavy metal ions, viz. Cd2+, Pb2+, Cu2+, and Hg2+, which showed superior performances for both individual as well as simultaneous detections. For simultaneous detection of Cd2+, Pb2+, Cu2+, and Hg2+. Moreover, the Pd/PAC-modified GCEs is also show perspective applications in detection of metal ions in real sample, as illustrated in this study for a milk sample. In addition, the synthesis of highly dispersed and stable ruthenium nanoparticles (RuNPs; ca. 2–3 nm) on porous activated carbons derived from Moringa Oleifera fruit shells (MOC) is reported. The as-prepared MOC carbonized at 900 oC was found to possess a high specific surface area (2522 m2 g−1) and co-existing micro- and mesoporosities. Upon incorporating RuNPs, the Ru/MOC nanocomposites loaded with modest amount of metallic Ru (1.0‒1.5 wt%) exhibit remarkable electrochemical and capacitive properties, achiving a maximum capacitance of 291 F g‒1 at a current density of 1 A g‒1 in 1.0 M H2SO4 electrolyte. These highly stable and durable biomass carbons modified electrodes, which can be facily fabricated by the eco-friendly and cost-effective route, should have great potentials for practical applications in energy storage, biosensing, and catalysis.

Title: Fatigue Life and Anti-loosening Performance Improvement of Bolt-Nut Connections Having Pitch difference and Changing Thread Geometry

Abstract: In a wide industrial field, the bolt-nut joint is unitized as an important machine element and widely used. To ensure the safety of the structure and reduce cost, low-cost bolt-nut connections with good anti-loosening performance and high fatigue strength are always required. In this study, the effect of slight pitch difference between bolt and nut is considered through finite element analysis. Then, the fatigue life improvement mechanism is considered by investigating the crack location in the experiment with FEM analysis. In addition, in order to improve the fatigue life more effectively, the large root radius of bolts and nuts is considered both experimentally and analytically. And the 3D FEM results show that a large pitch difference may provide large prevailing torque that causes an anti-loosening. By taking into account the anti-loosening and fatigue strength, the most suitable pitch difference is proposed to improve anti-loosening performance and fatigue life.
