In the present technological era, energy storage devices like batteries and supercapacitors hold immense importance, and their hybrid variants have gained notable interest. The aim of this study was to develop a dual-linker ...
An optimized CT-dense agent perfusion and micro-CT imaging protocol for chick embryo developmental stages.
(
BMC
, 2024 , Article)
Compared to classical techniques of morphological analysis, micro-CT (μ-CT) has become an effective approach allowing rapid screening of morphological changes. In the present work, we aimed to provide an optimized micro-CT ...
Robust and General Model to Forecast the Heat Transfer Coefficient for Flow Condensation in Multi Port Mini/Micro‐Channels
(
Multidisciplinary Digital Publishing Institute (MDPI)
, 2022 , Article)
A general correlation for predicting the two‐phase heat transfer coefficient (HTC) during condensation inside multi‐port mini/micro‐channels was presented. The model was obtained by correlating the two‐phase multiplier, ...
Broadband vibration energy harvesting from a non-deterministic system: Performance of different piezoelectric patch shapes
(
IOP Publishing Ltd
, 2021 , Article)
Harvesting energy from ambient structural vibration using piezoelectric materials gained massive interest in the past decade. Piezoelectric harvesters can be incorporated in many applications; however, one of the main ...
Enhancing the damping effect of MRF damper using an external magnetic excitation system
(
Institute of Physics Publishing
, 2023 , Article)
The magnetic field generated by the damper’s magnetic circuit governs the yield stress value of the Magnetroholgical Fluid (MRF) damper and hence its damping effect. This paper contributes to the literature on the development ...
Development of eco-friendly chitosan-g-polyacrylamide preformed particle gel for conformance control in high-temperature and high-salinity reservoirs
(
Elsevier
, 2023 , Article)
Oil and gas extraction has become challenging nowadays due to the accompanying amount of excess produced water that results in poor recoverability of hydrocarbon, besides other environmental and economic isues. A recent ...
