Hierarchical Flexible Ceramic Nanofiber Membrane for Simultaneous Membrane Distillation and Photocatalytic Hydrogen Evolution

open access: yesAdvanced Materials, EarlyView.
A hierarchical flexible ceramic nanofiber membrane integrates a La‐stabilized ZrO2 scaffold with superhydrophobic UiO‐66‐NH2/CdS heterojunctions. The gas–liquid–solid interfacial architecture sustains vapor‐selective desalination, visible‐light charge separation, and rapid H2 extraction, enabling simultaneous freshwater production and photocatalytic ...

Study on Dynamic Behavior of Disperse Phase Water Droplets in Non-uniform Electric Field

open access: yesShiyou jixie, 2018
To study the dynamic behavior and influencing factors of disperse phase water droplets in a non-uniform electric field formed by tubular electrodes, a physical model of water droplets in a non-uniform electric field is established using phase-field ...

Population Balance Modeling of Breakage and Coalescence of Dispersed Bubbles or Droplets in Multiphase Systems

open access: yes, 2016
Modeling of breakage and coalescence of dispersed phases such as bubbles or droplets in multiphase systems is of paramount importance to the control of the dispersed phase size distribution in process industry. Population balance model (PBM) has become

Lattice Strain and Built‐In Field Synergistically Boost Urea Oxidation via Dynamic NiOOH Mediation at Multiphase Heterointerfaces

open access: yesAdvanced Materials, EarlyView.
A sulfur‐doped lignin‐derived carbon‐coated Ni‐NiO‐MoO2 nanorod array was synthesized, exhibiting enhanced UOR performance ‐ due to lattice‐strain and built‐in electric field effects by multiphase heterogeneous interface in Ni‐NiO‐MoO2@SC, excellent corrosion resistance, mass‐transport ability, and long‐term stability (500 mA cm−2 at 1.53 V for 500 h ...

Mathematical modeling of the motion of two immiscible media with moving interfaces

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки
This article presents the results of a numerical study on the dynamics of gas bubbles in a viscous liquid under the action of gravity. The rise of a single bubble, two bubbles starting at the same level relative to the vessel bottom, and bubbles rising ...

Crack propagation and coalescence in brittle materials under compression

open access: yes, 1998
Two particular cases concerning crack propagation and coalescence in brittle materials have been modeled by using the rock failure process analysis code, RFPA(2D), and the results have been validated by reported experimental observations.

Topological Spin‐Texture Transitions in van der Waals Magnets Revealed by X‐Ray Fourier Transform Holography

open access: yesAdvanced Materials, EarlyView.
Applied here for the first time to a 2D material, high‐resolution synchrotron x‐ray Fourier transform holography directly images topological spin textures in Fe3GeTe2. Combined with atomistic tight‐binding simulations including itinerant electrons and Rashba spin‐orbit coupling, the approach reveals labyrinth, skyrmion, and mixed phases, and uncovers ...

Dynamic Electrophoretic Assembly Coupled With Water‐Splitting‐Induced pH Control Enables Precision Ion Sieving Membranes

open access: yesAdvanced Materials, EarlyView.
A green, external‐catalyst‐free route grows defect‐free covalent organic framework membranes directly on ion‐exchange supports using an alternating electric field and in situ‐generated acid. Through a self‐regulating, self‐healing mechanism, the membranes achieve near‐complete, ultra‐fast separation of monovalent ions such as Li+, Na+, and K+, offering
