Preparation and characterization of high surface area activated carbon from Fox nut (Euryale ferox) shell by chemical activation with H3PO4

open access: yesResults in Physics, 2016
Activated carbons were prepared from Fox nutshell by chemical activation with H3PO4 in N2 atmosphere and their characteristics were studied. The effects of activation temperature and impregnation ratio were examined. N2 adsorption isotherms characterized

On the Analysis of the Activation Volume

open access: yesZeitschrift für Naturforschung A, 1976
Abstract The stress and temperature dependence of the activation volume is often explained by a similar dependence of the measured stress sensitivity. This explanation cannot be reconciled with the nonconservative motion of jogs, with dislocation climb, nor with the intersection mechanism.

Adsorption of Carbon Dioxide onto Activated Carbon Prepared from Coconut Shells

open access: yesJournal of Chemistry, 2015
This study presents the fabrication of high-quality activated carbon (AC) from discarded coconut shells. The effects of experimental parameters such as activation temperature and activation time on the basic characteristics of AC, including charcoal ...

A Model of Enhanced Strain Rate Sensitivity in Nanocrystalline and Ultrafine-Grained Metals

open access: yesReviews on Advanced Materials Science, 2018
A model is suggested that describes enhanced strain rate sensitivity of nanocrystalline and ultrafine-grained metals. Within the model, plastic deformation of such metals incorporates dislocation transmission across grain boundaries (GBs) in the stress ...

AMPK mediates regulation of glomerular volume and podocyte survival

open access: yesJCI Insight, 2021
Herein, we report that Shroom3 knockdown, via Fyn inhibition, induced albuminuria with foot process effacement (FPE) without focal segmental glomerulosclerosis (FSGS) or podocytopenia. Interestingly, knockdown mice had reduced podocyte volumes.

Mean platelet volume in patients with nasal polyposis

open access: yesB-ENT, 2012
Mean platelet volume in patients with nasal polyposis. Objective: To investigate whether mean platelet volume (MPV) levels rise in patients with nasal polyposis (NP) and whether higher MPV levels are correlated to the extension of polyps in these ...

The Ion Transporter NKCC1 Links Cell Volume to Cell Mass Regulation by Suppressing mTORC1

open access: yesCell Reports, 2019
Summary: mTORC1 regulates cellular growth and is activated by growth factors and by essential amino acids such as Leu. Leu enters cells via the Leu transporter LAT1-4F2hc (LAT1).

Activation volumes in lead halides and other solids

open access: yesPhysical Review B, 1986
Conductivity measurements of ${\mathrm{PbCl}}_{2}$ and ${\mathrm{PbBr}}_{2}$ under pressure have been carried out by Oberschmidt and Lazarus. The migration and activation volumes scale with the corresponding enthalpies in a manner predetermined by the bulk properties.
