Direct Synthesis of Graphene Quantum Dots with Different Fluorescence Properties by Oxidation of Graphene Oxide Using Nitric Acid

Applied Sciences, 2018
Graphene quantum dots (GQDs) play a critical role in many applications in the electrical and optical fields. We develop a simple three-step hydrothermal etching method to prepare GQDs by adopting graphene oxide (GO) as a precursor and nitric acid as an ...

Nitric Acid Extraction into TODGA

Procedia Chemistry, 2012
AbstractAdvanced solvent extraction processes, namely DIAMEX, SANEX or GANEX, for the separation of the minor actinides (americium and curium) are under development within Europe. The tridentate diglycolamide ligand, TODGA, shows many interesting properties and is under investigation in conjunction with a variety of other extractants for the DIAMEX and

Nitric Acid Pretreatment of Jerusalem Artichoke Stalks for Enzymatic Saccharification and Bioethanol Production

Energies, 2018
This paper evaluated the effectiveness of nitric acid pretreatment on the hydrolysis and subsequent fermentation of Jerusalem artichoke stalks (JAS). Jerusalem artichoke is considered a potential candidate for producing bioethanol due to its low soil and

Amount and Composition of NOx Generated by Metal (Cu, Ni, and Fe) Dissolution Reaction with Nitric Acid

Journal of Chemical Engineering of Japan
In metal dissolution processes, the amount and composition of NOx generated by a reaction using nitric acid vary with complex factors. To treat harmful NOx generated by metal dissolution with nitric acid, the amount and composition of generated NOx was ...

EFFECTS OF KAINIC ACID ON GLUTATIONE AND NITRITE IN RAT HIPPOCAMPUS [PDF]

Journal of IMAB, 2011
Epileptiformic activity could result in apoptotic neuronal death, in which oxidative stress could play an important role. In case of decreased antioxidant brain status cellular death could be facilitated.

Studies on the optimal electrodeposition of actinium in alcohol-based electrolytes

Fushe yanjiu yu fushe gongyi xuebao, 2022
To determine the optimal electrodeposition conditions for actinium in a nitric acid/ethanol electrolyte, the 228Ac nuclide was used for electrodeposition experiments in a nitric acid/ethanol electrolyte in this study. First, under a current of 0.1 A, the

Synthesis of Butyric Acid Nitrification Derivatives and Adiabatic Thermal Analysis of Reaction With Nitric Acid

He huaxue yu fangshe huaxue
Tributyl phosphate(TBP) undergoes stepwise degradation in the post-treatment system to produce butanol, which is ultimately converted into butyric acid. Butyric acid can gradually accumulate in the system and undergo nitration reactions triggered by free
