Ion beam irradiation is a promising approach to fabricate nanoporous graphene for various applications, including DNA sequencing, water desalination, and phase separation. Further advancement of this rational design experiments all require improved mechanistic understanding the physical drilling process. Here, we demonstrate that, by using oblique ion irradiation, nanopore family significantly expanded include more types nanopores tunable geometries. With hopping, sweeping, shoving...
To design microstructure and microhardness in the additive manufacturing (AM) of nickel (Ni)-based superalloys, present work develops a novel data-driven approach that combines physics-based models, experimental measurements, data-mining method. The simulation is based on computational thermal-fluid dynamics (CtFD) model, which can obtain thermal behavior, solidification parameters such as cooling rate, dilution solidified clad. Based computed information, dendrite arm spacing are estimated...
Scoliosis, an abnormal curvature of the human spinal column, is characterized by a lateral deviation spine, accompanied axial rotation vertebrae. Adolescent Idiopathic Scoliosis (AIS) most common type, affecting children between ages 8 to 18 when bone growth at its maximum rate. We propose mechanistic machine learning algorithm in order study patient-specific AIS curve progression, which associated with and other genetic environmental factors. Two different frameworks are used analyse...
Laser stealth dicing can realize material separation with negligible surface damage, but severe aberrations in thick materials degrade processing quality. This Letter presents a nonlinear point-to-point transformation method combined spherical aberration compensation to achieve aberration-free axial multi-focus beams. The focus peak intensity increases 7 times at depth of 0.5 mm after compensation, and reaches 44 3.5 mm. Spherical experiments showed that the width heat-affected zone remains...
Fe<sub>3</sub>O<sub>4</sub>@P(DVB/MAA)/Pd composite microspheres were synthesized with a combination of coating and loading processes using Fe<sub>3</sub>O<sub>4</sub> nanoparticles as core.
This paper presents the concept of reduced order machine learning finite element (FE) method. In particular, we propose an example such method, proper generalized decomposition (PGD) hierarchical deeplearning neural networks (HiDeNN), called HiDeNN-PGD. We described first HiDeNN interface seamlessly with current commercial and open source FE codes. The proposed method can reduce significantly degrees freedom for physics based modeling is able to deal high dimensional problems. found more...
We report an efficient method to generate arbitrary three-dimensional (3D) parallel multifoci inside a material. Taking into account the numerical aperture of objective lens and refractive index material, Ewald cap was modified with longer radius, then whole 3D intensity distribution material could be calculated using only single Fourier transform (FT). By introducing adaptive weight coefficient, uniformity improves from 81.3% 98.9%. adjusting axial resolution cap, 85.9% 99.7%. In...
It is of great significance to control the energy, location, topological charge, and other parameters each beam in three-dimensional space. Thus, optical array proposed widely used processing, communication, microscopy, storage, fields. However, current methods generate are only effective specific scenarios. In this work, we present an efficient general method, which separates iterative calculation parameter selection by introducing a special mapping space, allowing generation arrays with...
Abstract Fully buried portal frame-shaped piles have been widely used to control and stabilize large-scale landslides or slopes. However, the working mechanism of frame piles, such as soil–pile interaction load transfer behavior, is still not fully understood, which has limited development effective pile designs construction. In this study, a well-designed laboratory model test was conducted in sandy soil slope with man-made slip surface. Nine were installed, synthetically considering...
Axial light distribution modulation is widely applied in optical tweezers, hard-brittle material cutting, multilayer laser direct writing, etc. To generate arbitrary axial distribution, the coordinate-transformation iteration (CTI) algorithm presented. The CTI unifies equations low and high numerical aperture (NA) scenarios, using same iterative to produce phase computer-generated holograms. In a NA scenario, twin-foci, flattop, sin2 distributions have been achieved. multirings, multifoci,...
Aperture, flexibly defined as common-seen periphery-blocked structures, or special-shaped patterns, even with artificial-designed complex amplitude modulating function, are inevitably a core limitation of optical system that deteriorates the beam modulation performance. To bridge gap between ideal simplified phase and real aperture-constrained system, we propose an inverse design algorithm (GOODBAP) which uses cascaded holograms to achieve arbitrary intensity distribution behind aperture....
