The climbing capabilities of living creatures such as geckos, tree frogs, and inchworms provide a promising platform for exploiting biomimetic soft robots, but achieving this promise remains grand challenge in materials science engineering. Inspired by the adhesive characteristics gecko toes gait inchworms, here, we exploit synergetic interactions functional material components design hybrid structure holistic robot, which can climb on walls ceilings different textures including glass,...
The biocompatibility of iron-polysaccharide complexes has been well-documented. Herein, a stable thrombo-resistant coating was fabricated by consecutive adsorption Fe (III) and polysaccharides including heparin (Hep) dextran sulfate (DS) onto various surface layer-by-layer self-assembly technique via both electrostatic interaction chemical complexation process. absorbance at 350 nm increased linearly with the number Fe3+/Hep multilayer, indicating formation multilayer structure uniform...
Abstract In this paper, a multilevel correction scheme is proposed to solve the Steklov eigenvalue problem by nonconforming finite element methods. With new scheme, accuracy of eigenpair approximations can be improved after each step which only needs source on finer space and an coarsest space. This increase overall efficiency solving problems method. Furthermore, as same direct methods, method also produce lower-bound eigenvalues.
We developed a driving module which enables the transmission of motion from liquid metal droplet out alkaline solution environment and its output readily meets some application scenarios that need low-speed rotation.
Abstract An efficient numerical method with high accuracy both in time and space is proposed for solving ‐dimensional fractional diffusion equation spectral Laplacian. The main idea discretizing the by an ‐stage implicit Runge‐Kutta approximating a Galerkin Fourier‐like basis functions. In view of orthogonality, mass matrix identity stiffness diagonal, which makes high‐dimensional problems. showed to be stable convergent at least order time, when classical () algebraically stable. As another...
Flocculation can remove large amounts of nitrogen and phosphorus from wastewater, the resulting nitrogen- phosphorus-rich floc be used to produce organic fertilizer. For biogas slurries containing high levels phosphorus, ordinary flocculants no longer meet flocculation requirements. In this study, fully utilize advantages two achieve efficient removal rates a slurry, chitosan (CTS) polyaluminum chloride (PAC) were as composite agent flocculate pig slurries. The response surface method was...

After immobilization, maximum biomass increased 2.7 times rate rates chemical...
In this paper, we discussed the gangue on mining area that have bad economic and environmental impact. It has been shown coal accumulation could seriously prevent regional ecological sustainable development. Pollution control technology is key to solve problem. So analyzed it divided into three categories: prophylaxis treatment of pollution geologic hazard, hill vegetation restoration comprehensive utilization technology.
