Abstract Low-dimensional materials exhibit unique quantum confinement effects and morphologies as a result of their nanoscale size in one or more dimensions, making them distinctive physical properties compared to bulk counterparts. Among all low-dimensional materials, due atomic level thickness, two-dimensional possess extremely large shape anisotropy consequently are speculated have optically anisotropic absorption. In this work, we demonstrate an optoelectronic device based on the...
Electrochromic effect refers to the electrically tunable coloration of a matter. Emerging see-through color-tunable applications pose synergetic demand on electrochromic device, concurrently having ultralow field driving, operation in transmissive mode, and high-purity interference colors sci-fi perception. However, such an device remains elusive. Herein, we invent electro-interference-color based two-dimensional titania liquid crystals (2D TiO 2 LCs), demonstrating record-high...
The interfacial bonding between carbon fibers and the resin matrix affects mechanical properties of fibers, increase modulus brings a challenge to fibers. traditional anodic oxidation with ammonium bicarbonate as an electrolyte has limited effect on surface treatment for high-modulus In this paper, acidic is used treat influence mechanism graphitized structure anodizing reaction fiber was studied. Raman spectroscopy, XPS, scanning electron microscopy, dynamic contact angle, micro-debonding...
Nanopantography is a method for massively parallel patterning of nanofeatures over large areas. Transfer patterns defined by nanopantography using highly selective plasma etching Si, with the native silicon oxide as hard mask, can improve speed and etch profile. With this method, arrays high aspect ratio (>5) ∼10 nm-diameter holes, well slots, were fabricated in no mask undercut. The ability to fabricate complex nanopantography, followed etching, was also demonstrated.

Programmable instability is crucial to the design of intelligent structures. Origami has inspired new methods designing spatial truss structures with programmable instability. In this study, finite-particle method was used investigate modes based on Miura-ori, an origami pattern. Truss models single-layer and multilayer Miura tube–based were established. The process for each structure simulated, structure’s stiffness, strain energy, processes studied. these controlled through adjustment two...
Composite materials composed of multiferroelectric nanoparticles in dielectric matrixes have attracted enormous attention for their potential applications developing future functional devices. However, the functionalities ferroelectric depend on shapes, sizes, and materials. In this paper, a time-dependent Landau-Ginzburg method has been used combined with as coupled-physics finite-element-method-based simulations are to illustrate polarization behavior isolated BaTiO3 or PbTiO3 octahedral...
The in situ evaluation of pile-soil bonding condition plays an important role for pile safety assessment its life cycle. However, so far, there is still no fully mature tool to analyze such couplings, since the coupling exhibits complex and time-varying relationships. This paper innovatively proposes a health monitoring approach evaluate status soil contact area. An impact method based on piezoelectric ceramic sensor proposed monitor bond soil. A horizontal was introduced near top pile,...

First, a broadband time inversion signal coherent synthesis model is established based on distributed array. On this basis, the change of domain, frequency domain and auto-correlation characteristics after studied. Under condition random phase modulation amplitude for signal, variation synthetic superposition gain affected by Time Position Difference also The focusing modulated under are preliminarily explored. conclusion can provide theoretical basis application in engineering.
This paper presents experimental study on effects of width-to-thickness ratio and loading history cyclic rotational capacity H-shaped steel beams subjected to pure bending. Eight Class 3 4 with large ratios were tested under four different histories. The coupling effect local buckling cracking the specimens was investigated. It found that loss load-carrying mainly induced by buckling, ductile a secondary factor. plays dominant capacity, also an important role. can decrease significantly due...
Locomotive traction gear is the key component to power transmission and speed control in locomotive system, which plays an important role running load-carrying torque. Considering that there not universal rule for method of modification at present, this paper, tooth profile considered with combination increased contact ratio variation moment arm action. Based on principle modification, according load direction after change action determined, interval range also determined. Taking a certain...
In order to reduce the volume and mass of locomotive's traction gearbox, Firstly, theoretical statics analysis gear box is carried out on basis establishing model. Then was statically analyzed in ANSYS work bench software, it can be seen that which factors have a relatively large impact stress strain, where gearbox most affected by strain deformation, best wall thickness selected according parameters optimization structure.
This paper use the method of finite element analysis, and comparing analyzing split box integrated from two aspects modal analysis static analysis. It is concluded that has characteristics excellent vibration high strength tolerance; At same time, according to S-N curve material load spectrum box, fatigue life 26.24 years by using software Fe-safe, which meets service requirements; The reliability module PDS used calculate 96.5999%, performance requirements.
