Superhydrophobicity of multiscale hierarchical structures and bouncing phenomenon a water droplet on the superhydrophobic surface were studied. The carbon nanotube/ZnO ZnO/carbon nanofiber produced by hydrothermal method. structure showed superhydrophobicity with static contact angle (CA) larger than 160° due to increased air pockets in Cassie-Baxter state. effect observed nanostructure was explained free energy barrier (FEB) analysis finite element simulation. low FEBs which provoke high CA...
UV-curable high-viscosity ZrO2 ceramic nanocomposite resins were prepared for use in supportless stereolithography 3D printing. To improve their dispersion stability and photo-curing properties, the mixing ratio of nano- micro-particles was optimized to 70:30 by volume, surfaces mixed particles functionalized with acrylate groups through hydrolysis condensation a silane coupling agent (APTMS, 3-acryloxypropyl trimethoxysilane). APTMS-coated dispersed mixtures di- tri-functional monomers...
We introduce a multiplex particle focusing phenomenon that arises from the hydrodynamic interaction between viscoelastic force and Dean drag in microfluidic device. In confined microchannel, first normal stress difference of fluids results lateral migration suspended particles. Such was harnessed to focus different sized particles middle microchannel spiral channel geometry also considered order take advantage counteracting force, induces outward direction. For theoretical understanding, we...
We aimed to determine the relationship between surface chemistry and rheological properties of silicon anode slurries in lithium-ion batteries. To accomplish this, we investigated use various binders such as PAA, CMC/SBR, chitosan a means control particle aggregation improve flowability homogeneity slurry. Additionally, utilized zeta potential analysis examine electrostatic stability particles presence different binders, results indicated that conformations on can be influenced by both...
Abstract Carbon nanotubes (CNTs), owing to their superior electrical and mechanical properties, are a promising alternative nonmetallic electrically conducting materials. In practice, cellulose as low‐cost sustainable matrix has been used prepare the aqueous dispersion of cellulose‐CNT (C‐CNT) nanocomposites. However, compatibility with conventional solution‐processing structural rearrangement for improving conductivity yet be determined. Herein, straightforward route conductive composite...
Abstract Bacterial biofilms present significant challenges across microbiology, environmental science, water management, and healthcare. This study employs Quartz crystal microbalance with dissipation monitoring (QCM-D) interfacial rheology system (IRS) for in situ analysis of Escherichia coli biofilm growth viscoelastic properties. By development at both bulk micro scales real-time, we identified three distinct phases: surface attachment initial growth, maturation, dispersion. Optimal...
Particles in a viscoelastic fluid are typically focused at the center and four corners of rectangular channel because combination elasticity inertia forces. In this study, we observe transition between single-line multiple-line particle focusing microfluidic device induced by synergetic effect viscoelasticity. The elastic inertial forces acting on suspended particles manipulated controlling concentration dilute polymer solution flow rate fluid. finding shows that confinement effects...
The high separation efficiency of particles and cells can be realized by exploiting a facile two step label free technique that consists elasto-inertial focusing magnetophoresis.
The localized surface plasmon resonance (LSPR) sensitivity of metal nanostructures is strongly dependent on the interaction between supporting substrate and nanostructure, which may cause a change in local refractive index nanostructure. Among various techniques used for development LSPR chip preparation, solid-state dewetting nanofilms offers fast cost effective methods to fabricate large areas given substrate. Most previous studies have focused effect size, shape, inter-particle distance...
