In this research, we reported a novel modified carbon ceramic electrode (CCE) using Ni/Al Layered double hydroxide as modifier was fabricated by sol-gel technique. The Ni/Al Layered double hydroxide modified sol gel derived carbon ceramic (Ni/Al LDH-SGD-CC) electrode was used for electrocatalytic oxidation of acetaldehyde. The oxidation of acetaldehyde happens at the potential where Ni (III) sp...
This study presents a review on advanced oxidation processes (AOP) for simultaneous removal of NO and SO2. AOP is based on using a strong oxidant such as ozone and H2O2 which is able to generate highly reactive intermediates. The pollutant will be oxidized and removed by these intermediates. In recent years, AOP has been considered as an effective and attractive technology in the field of flue ...
Background and Aim: 2,4-Dichlorophenol (DCP) is a compound generated in a variety of industrial processes and also by chlorine disinfection of water polluted with phenolic compounds . Dumping of DCP into the environment and water resources is of great concern because of the compound's intense odor and toxicity. DCP is very soluble and resistant to biodegradability so it cannot be removed throu...
compressed biscuits (cbs) were developed using wheat flour, soy flour, sugar, oil and malt extract. combining of compression and dehydration technology were applied for production. packaging cbs using vacuum packaged, use of oxygen absorber (oa) and identical samples were aerobically packaged and stored at ambient and elevated (40°с) temperature for 12 weeks. the effect of different packaging a...
In this study, ceramic coatings were prepared on AZ31B Mg alloy by plasma electrolytic oxidation technique in electrolytes containing sodium fluoride (KF), sodium silicate (Na2SiO3.5H2O) and different potassium hydroxide (KOH) concentrations. The electrochemical behavior of AZ31B alloy and plasma electrolytic oxidation coatings was studied by potentiodynamic polarization, electrochemical impeda...
The changes of protein expression that are monitored in proteomic experiments are a type of biological transformation that also involves changes in chemical composition. Accompanying the myriad molecular-level interactions that underlie any proteomic transformation, there is an overall thermodynamic potential that is sensitive to microenvironmental conditions, including local oxidation and hydr...
The present study is concerned with measuring and simulating soot formation and combustion in turbulent liquid fuel spray flames. Soot concentrations inside the combustor are measured by filter paper technique. The simulation is based on the solution of the fully-coupled conservation equations for turbulent flow, chemical species kinetic modeling, fuel droplet evaporation and combustion and...
The oxidation of lindane is investigated by photooxidation and photocatalytic procedures using solar light irradiation. The photocatalyst used in photocatalysis is Degussa P25 TiO2. The degree of oxidation is followed by chemical oxygen demand (COD) measurements. The oxidation process is carried out at different initial concentrations of lindane varying from 0.05×10 M to 1.0×10 M. The photooxid...
A novel trimacrocyclic arylamine was found to be accessible to the different spin-states by consecutive electrochemical or chemical oxidation.
Thank you for submitting your manuscript for consideration by the EMBO Journal. I apologise for the delay in getting back to you with a decision but we have still not received the final report from the third referee despite several reminders and telephone calls. Since the other two reviewers seem to be in fair agreement, I would like to provide you with a preliminary decision on your manuscript...
