Title: Synergy of Liquid and 2D Nanoflakes based Superlubricity
Abstract: In this work, the recent progress in liquid superlubricity would be discussed, especially the synergy of Liquid and 2D Nanoflakes based Superlubricity. First, we found that the superlubricity could be achieved with the lubrication of phosphoric acid. Thereafter, we extended the Superlubricity of phosphoric acid to mixture of acid and glycerol, and then, established an acid-based superlubricity system. We also synthesized an ionic liquid based on the reaction between ethylene glycol and Lithium salt, which could achieve superlubricity with a friction coefficient of 0.004. The superlubricity mechanism can be mainly attributed to the formed composite tribochemical layer. Thereafter, a robust liquid-superlubricity state (μ ≈ 0.005) under a pressure of 600 MPa was realized, which was enabled by the combination of graphene-oxide (GO) nanosheets with an ionic liquid between the frictional pairs of Si3N4/sapphire…

Title: Creative Thoughts on Precision Mechatronic Motion Control with Performance Orientation
Abstract: To meet the progressively stringent demands for trajectory tracking performance in precision/ultra-precision industry, the research on advanced mechatronic motion control methods has attacted more and more attentions. Several performance-oriented motion control strategies represented by extended iterative learning control, gated recurrent units control, and real-time iterative control, will be introduced from an interesting creative thought perspective. Various trajectory tracking tasks are accomplished on precision mechatronic motion stages, and the tracking performances to be examined include tracking accuracy, extrapolation capability for non-repetitive trajectories, and disturbance rejection ability. Experimental results are sufficiently summarized with underlying control mechanism analysis, which can provide a comprehensive and reliable selection guidance of feedforward compensation strategies in motion control of different practical industrial scenarios.

Title: Deep Learning-based Path Planning for Vehicles on 3D Map
Abstract: In the traditional vehicle area, energy-based motion control technology and battery technology usually use to solve the energy-saving problem. Our research proposes a new solution from the perspective of path planning. For vehicles traveling on the complex 3D terrains, the energy consumption of up-slope is far greater than that of the flat road and down-slope. To realize this, a path with a good trade-off between the energy consumption and distance would be the expected route for electric vehicle and mining transportation. A novel multi-objective path planning method is investigated to solve this problem for EV and mining truck. The simulation experiments prove that the proposed method can generate an optimal path which saves much energy in comparison with the path provided by the distance-based method.

Title: Rapid solid state volumetric additive manufacturing for any environment
Abstract: Rapid 3D printing on space/air/sea missions, where either gravitational force is missing or severe random disturbance may present continuously, is highly in demand. However, till today, there is no reliable technique for such working environments. The purpose of this study is to develop a technology for rapid 3D printing in solid state of polymeric materials for any environment, including those harsh environments.
The basic concept is to cross-link by either UV-light or photo-induced-heat of polymeric materials in the solid state for rapid 3D printing. The uncross-linked parts can be removed by heating or cooling for melting, or washing away by solvent. Finally, the shape memory effect (SME) of the cross-linked polymers is applied to ensure high accuracy of the printed items…
