CONVECTIVE HEAT TRANSFER COEFFICIENT OF INDIAN GOOSEBERRY (EMBLICA OFFICINALIS) DRIED IN THREE DIFFERENT FORMS UNDER FORCED CONVECTION MODE [PDF]

open access: yesJournal of Engineering Science and Technology, 2012
In this paper, convective heat transfer coefficient of Indian gooseberry (Emblica officinalis), in three different forms (shreds, slices and pieces), under forced convection mode has been determined. These forms were dried in laboratory drier.

Integrity of Newton’s cooling law based on thermal convection theory of heat transfer and entropy transfer

open access: yesScientific Reports, 2022
Although thermal convection is omnipresent in nature and technology and serves important purposes in various energy transport systems, whether convection can be viewed as an independent heat transfer means has long been argued The constant coefficient in

On the scaling of convective boiling heat transfer coefficient

open access: yesInternational Journal of Heat and Mass Transfer, 2021
Abstract Flow boiling has been widely used during the last century, but the key mechanisms controlling the heat transfer process still remain elusive. In the particular case of convective flow boiling inside a heated pipe, most of the existing correlations have been proposed assuming an enhancement factor to the liquid Reynolds number.

Highly Sensitive Electrochemical Biosensor Based on Hairy Particles with Controllable High Enzyme Loading and Activity

open access: yesAdvanced Functional Materials, EarlyView.
For the first time, a highly sensitive electrochemical biosensor based on SiO2‐based hairy particles with a grafted PDMAEMA polymer brush containing a quantifiable and large amount of immobilized Laccase is reported. The fabricated biosensor exhibits a sensitivity of 0.14 A·m⁻¹, a limit of detection (LOD) of 0.1 µm, and a detection range of 0.3–750 µm,

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

open access: yesAdvanced Functional Materials, EarlyView.
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by
