Dirichlet problem for Laplace–Beltrami equation on hypersurfaces—FEM approximation

, 2016
We consider Dirichlet boundary value problem for Laplace–Beltrami Equation On Hypersurface S, when the Laplace–Beltrami operator on the surface is described explicitly in terms of Günter’s differential operators. Using the calculus of Günter’s tangential

3D printing of fluorine‐free omniphobic surfaces

Droplet, EarlyView.
Our work demonstrates that the simple and inexpensive digital light processing three‐dimensional printing can be used to fabricate micropillar arrays with doubly reentrant and triply reentrant features. The printed fluorine‐free surfaces display omniphobicity and resist the wetting of liquids with a wide range of surface tensions.

Photothermal bubble: Dynamics, manipulation, and applications

Droplet, EarlyView.
As a versatile platform for bubble manipulation, photothermal techniques empower diverse operations: planar translation by scanning the laser spot, sustained periodic bouncing from competing thermal and hydrodynamic flows, and even guided 3D trajectories achieved by tailoring the heating configuration.

Enhancing hydrogen evolution reaction by harnessing bubble dynamics regulation: Principles, methods, and outlook

Droplet, EarlyView.
Bubble dynamics pose critical bottlenecks to hydrogen evolution reaction efficiency, causing active site isolation, increased ohmic resistance, and concentration overpotential, especially at high current densities. This review comprehensively summarizes passive and active bubble manipulation strategies, elucidates their underlying principles, and ...

Photothermal–Magnetocaloric Coupled Evaporators for Actively Adjustable Water Evaporation and Oil–Water Purification in Complex Environments

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A photothermal–magnetocaloric coupled aerogel evaporator is developed for actively adjustable water evaporation in complex environments. Magnetocaloric heating provides active energy compensation under low‐light conditions and disrupts interfacial hydrogen‐bond networks to promote evaporation.

Enabling Ultrastable Microbubbles With Graphene Aerogel Enrichment and Machine Learning for Highly Efficient Carbon Storage

Electron, EarlyView.
This study aims to introduce a novel‐designed structure of the colloidal aphron microbubbles reinforced by incorporating hydrophobic aerographene microparticles onto the hydrophobic outer shell. This results in the formation of a robust composite film and armored microbubble that offers exceptional ultrastability under elevated pressures of up to 400 ...

Design and Experimental Study of Pressure Maintenance and Temperature Control System for Hydrate Pressure Core Processing Device

Energy Science &Engineering, EarlyView.
This paper presents a hydrate pressure core processing device integrated with a high‐precision active control system to perform nondestructive transfer, cutting, and analysis. To address the limitations of slow dynamic response and high thermal inertia in traditional passive systems, a differentiated control scheme is implemented.

A critical fractional Laplace equation in the resonant case

, 2014
In this paper we complete the study of the a non-local fractional equation involving critical nonlinearities depending on a real parameter, started in some recent papers by the same authors (joint with other coauthors). Aim of this paper is to study this
