Electronic Control System for Optimized Resonance Operation of Dielectric Elastomer Pumps through Self‐Sensing

open access: yesAdvanced Engineering Materials, EarlyView.
A powerful electronic control system enables a dielectric elastomer pump to operate at resonance, matching conventional pump performance. Using self‐sensing to reconstruct load pressure dynamically, the adaptive control adjusts resonance frequency accordingly.

Stability of Radial Flow Subjected to a Radial Magnetic Field

open access: yesRajshahi University Journal of Science, 2013
The linear stability of radial flow of a viscous fluid in the presence of a radial magnetic field is investigated. Basic velocity field q0 = (c/r,0,W) and magnetic field B0= (A/r,0,0) are considered in an annulus between two concentric cylinders. To analyze hydro-magnetic stability, inner product method is employed.

ON THE OCCASION OF THE 150TH ANNIVERSARY OF DARCY'S LAW

open access: yesRudarsko-geološko-naftni Zbornik, 2005
In the end of this year it will be a 150 years since Henry Philibert Gaspard Darcy (1803-1858) has performed first experiments which were a year after followed by publication of the famous monograph «Les fontaines publiques de la ville de Dijon ...

Nano‐Patterned CuO Nanowire Nanogap Hydrogen Gas Sensor with Voids

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
Sub‐5‐ppb hydrogen (H2) detection and sub‐10‐s response and recovery times are achieved based on nano‐patterned polycrystalline CuO nanowires nanogap gas sensors with voids using electron‐beam lithography and unique annealing processes. Pre‐H2 annealing, void‐generating oxidation, and downscaled nanogap electrodes are key to improving the sensing ...
