Enhanced Electrochemical Properties of Biobased Activated Carbon for Supercapacitors

open access: yesAdvanced Engineering Materials, EarlyView.
Biobased activated carbons with diverse properties (pore size distribution, electrical conductivity, capacitance) for supercapacitors applications are synthesized and tested, using renewable biomass as versatile raw materials with disparate inherent heteroatom and molecular building blocks.

Can Cu(II) ions be doped into the crystal structure of potassium hydrogen tartrate? [PDF]

open access: yesarXiv, 2015
The differing binding preferences of the hydrogen tartrate ligand (HC4H4O6)- namely {\mu}7-octadentate mode for potassium ion and bidentate mode for cupric ion rules out the doping (incorporation) of any Cu(II) ion into the crystal structure of potassium hydrogen tartrate. Hence, the claim of growth of copper doped potassium hydrogen tartrate viz.

Lack of direct evidence for a functional role of voltage-operated calcium channels in juxtaglomerular cells [PDF]

open access: yes, 1990
In this study we have examined the role of voltage-gated calcium channels in the regulation of calcium in juxtaglomerular cells. Using a combination of patch-clamp and single-cell calcium measurement we obtained evidence neither for voltage-operated ...

Enhanced Mechanical Properties of Injectable Chitosan–Guar Gum Hydrogel Reinforced with Bacterial Cellulose Nanofibers for Tissue Engineering Applications

open access: yesAdvanced Engineering Materials, EarlyView.
This study presents the development and characterization of injectable nanocomposite hydrogels based on N‐succinyl chitosan, oxidized guar gum, and bacterial cellulose nanofibers. Emphasizing enhanced mechanical properties and biocompatibility, the hydrogels exhibit fast gelation, improved structural integrity, and reduced swelling. Their potential for

The effect of some soil parameters on the total alkaloid levels of tubers of Bongardia chrysogonum in three regions of Iran

open access: yesیافته‌های نوین در علوم زیستی, 2015
The tubers of Bongardia chrysogonum, belonging to to Podophyllaceae, are rich in alkaloids. In this study, total alkaloid content of the tubers of this plant in Naghadeh, Zanjan and Boukan were determined by spectrophotometeric method.
