Travelling wave for absorption-convection-diffusion equations

open access: yesElectronic Journal of Differential Equations, 2006
In this paper, we use the phase plane method for finding finite travelling waves solutions for the diffusion-absorption-convection equation $$ u_t=A(|u_x|^{p-2}u_{x})_x+B(u^n)_x-Cu^q, quad (x,t)in mathbb{R}imes mathbb{R}^{+}.

Solution of convection–diffusion equation by the method of characteristics

open access: yesJournal of Computational and Applied Mathematics, 2004
The author considers the nonlinear problem: \[ \partial_tu+ F(u) \nabla u-D\Delta u=0;\quad u(0,x)= u_0(x)\;x\in\Omega \] with homogeneous boundary conditions. This problem is solved by the method of characteristics. One of the innovations in the paper is that the velocity field must not be bounded, it is enough to be supposed continuous.

Omnidirectional Ultra‐Broadband Cu/TiO2 Metasurface Absorbers for High‐Efficiency Solar Thermal Conversion and Photothermal Plasmon‐Driven Catalysis

open access: yesAdvanced Optical Materials, EarlyView.
Metasurface shows selective solar–thermal energy conversion with high‐activity solar/laser‐driven chemistry. The breakthrough is co‐designing broadband FP‐cavity + plasmonic LSPR/SLR resonances in an ultra‐thin metamaterial so that it not only harvests the most efficient proportion of solar radiation but also suppresses mid and IR emissivity. Moreover,

Optically Active Birefringent Polymer–Lipid Hybrid Microparticles With Dual‐Stimuli Responsiveness

open access: yesAdvanced Optical Materials, EarlyView.
The present study reports on geometrically tunable, magnetic and NIR‐stimuli‐responsive anisotropic microparticles that exhibit intrinsic birefringence due to their lamellar crystalline architecture, enabling label‐free detection under a polarized light.

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators

open access: yesAdvanced Robotics Research, EarlyView.
We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.

A 3D Human Bone and Bone Marrow‐on‐a‐Chip Model for In Vitro Bone Remodeling and Immune Cell Maintenance

open access: yesAdvanced Science, EarlyView.
This study presents a human Bone (and Bone Marrow)‐on‐a‐Chip model based on native human bone scaffolds and autologous cells. Dynamic perfusion and sequential cell seeding replicate the physiological bone remodeling process in vitro, enabling the long‐term culture of functional, mature bone marrow immune subpopulations.
