Planar Solid‐State Nanopores Toward Scalable Nanofluidic Integration Based on CMOS Technology

Advanced Engineering Materials, EarlyView.
We present a scalable silicon‐based fabrication strategy for planar solid‐state nanopores to enable their integration with complex nanofluidic systems. Prototype devices demonstrate normal voltage‐current characteristics, good noise performance, and appreciable streaming currents. Our CMOS‐compatible fabrication process offers precise geometric control

On Jacobi fields and canonical connection in sub-Riemannian geometry

, 2017
Final version, to appear on Archivum MathematicumInternational audienceIn sub-Riemannian geometry the coefficients of the Jacobi equation define curvature-like invariants. We show that these coefficients can be interpreted as the curvature of a canonical

Prediction of Surface Topography Parameters in Direct Laser Interference Patterning of Stainless Steel Using Infrared Monitoring and Convolutional Neural Networks

Advanced Engineering Materials, EarlyView.
This study presents an infrared monitoring approach for direct laser interference patterning (DLIP) combined with a convolutional neural network (CNN). Thermal emission data captured during structuring are used to predict surface topography parameters.

Recurrence relations for connection coefficients between Q-orthogonal polynomials of discrete variables in the non-uniform lattice x(s)=q2S

, 1999
We obtain the structure relations for q-orthogonal polynomials in the exponential lattice and from these we construct the recurrence relation for the connection coefficients between two families of polynomials belonging to the classical class of discrete

A Thermodynamic 3D Model for the Simulation of Diffusion‐Controlled Alloying Processes in Heterogeneous Material Structures

Advanced Engineering Materials, EarlyView.
A numerical model resulting from irreversible thermodynamics for describing transport processes is introduced, focusing on thermodynamic activity gradients as the actual driving force for diffusion. Implemented in CUDA C++ and using CalPhaD methods for determining the necessary activity data, the model accurately simulates interdiffusion in aluminum ...

Connection Coefficients Between Generalized Rising and Falling Factorial Bases

, 2015
Let S = (s1, s2, . . .) be any sequence of nonnegative integers and let Sk = ∑ki=1si. We then define the falling (rising) factorials relative to S by setting (x) ↓k,S=(x - S1)(x - S2) · · · (x - Sk) and (x) ↑k,S= (x + S1)(x + S2) · · · (x + Sk) if k ≥ 1 ...
