Modelling aircraft fuel gauging unit using COMSOL multiphysics software
, 2011 An investigation was undertaken into the suitability of using COMSOL for modeling an aircraft capacitive fuel gauging unit. A model of a sensor immersed in a fluid was developed for rectangular tank geometry with a range of fluid levels and sensor ...

A Universal van der Waals Tunneling Injector for Monolayer CMOS
Advanced Materials, EarlyView.A universal van der Waals injector unlocks polarity‐flexible tunneling contacts for monolayer CMOS. SnSe2, an intrinsically degenerate 2D semiconductor, establishes polarity‐specific band alignments with both WSe2 and MoS2 channels, enabling steep switching, high on/off ratios, and a unified route to low‐power 2D logic.

Coupled PDEs with Initial Solution from Data in COMSOL 4
, 2013 COMSOL Conference 2013, Boston, MA, 2013Many physical applications require the solution of a system of coupled partial differential equations (PDEs). In most cases the analytic PDE solution does not exist for this system and we need to solve the problem ...

Ion Concentration and Voltage Imaging With Fluorescent Nanodiamonds
Advanced Materials, EarlyView.We demonstrate reversible switching between the fluorescent NV0 and the dark NV+ state, in sub‐30 nm FNDs via surface oxidation and hydrogenation, respectively. In an electrochemical cell, we show that the fluorescence from hydrogenated particles enables all‐optical imaging of voltages and ion concentrations at the micrometer scale.

Advanced 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

Conducting Finite Element Convergence Studies Using COMSOL 4.0
, 2010 Proceedings of the COMSOL Conference 2010 BostonIn order to gauge how reasonable a finite element solution to a partial differential equation is on a given mesh, a common strategy is to refine the mesh, compute the solution on the finer mesh, and use ...
