3.2 N2O decomposition over Cs-doped Cu50Ce50Ox catalysts Fig.8. Conversion of N2O over different Cs-doped Cu50Ce50Ox catalysts Conditions: 2600 ppm N2O, balance He, 0.3 Mpa, GHSV-19,000 h-1. Fig.9. The T50 and T100 of different Cs-doped Cu50Ce50Ox catalysts The activities of the catalysts with different Cs content for N2O decomposition are shown in Fig.8, and the T50 and T100 (the temperature at which 50% and 100% conversion of N2O decomposition is achieved) are shown in Fig.9. It’s found…

1.1 Overview: In a research lab, Mr. Z trying to formulate a colloidal dispersion system with sodium lauryl sulphate. What type of colloidal system is suitable for sodium laurly sulphate and also we have to discuss the different stability factors for sodium laurly sulphate dispersion. 1.2 Solution to the question: Introduction of colloids: Colloids are homogeneous non-crystalline substances. Here one substance is divide into more minute particles called colloidal particles and then it…

The purpose of this lab is to calculate a value for Avogadro’s number and compare it to the actual value for Avogadro’s number. Avogadro’s number will be determined by setting up an electrochemical cell to oxidize a copper electrode. The results of the amount of copper deposited and the average current used will be used to calculate a value for Avogadro’s number. Techniques used: In this experiment, different techniques will be used to collect the required data, such as taking the mass of…

Preparing Dilutions of the Silver Nanoparticles 1. Gather all materials. 2. Put on a pair of disposable gloves. 3. Make a paper towel damp with some 70% isopropyl rubbing alcohol. Wipe down the work surface with the rubbing alcohol-dampened paper towel. 4. Using a permanent marker, label the five baby food jars #1 to #5. 5. Using the 25 milliliter (mL) graduated cylinder, measure and pour 22.5 mL of distilled water (from a new, unopened container) into each of jars #2, #3, #4, and #5. 6. Using…

are cold. Dr. Richard L. Mueller defines TRPM8 as "an ion channel, upon activation it allows the entry of Na+ (sodium) and Ca2+ (calcium) ions to the cell that leads to depolarization and the generations of an action potential." In other words the TRPM8 cells open for sodium and calcium. However, in an article by Matt Soniak, he states that the TRPM8 ion cells don't only open to Na+ (sodium) and Ca2+ (calcium), but certain natural chemicals can activate TRPM8 on their own such as menthol that…

Purpose Ibuprofen is one of the most common over-the-counter medications. It reduces pain and inflammation by limiting certain hormones. The drug is taken orally, usually in the form of a pill, and is absorbed into the bloodstream once it dissolves. Both human saliva and human stomach acid aid in dissolving the pill. Human saliva has a pH of about 6, and stomach acid has a pH of approximately 2. The purpose of this investigation is to discover whether the pH of a solution will affect the time…

3. Preparation of microemulsion:- Microemulsion was prepared by dispersing required quantity of Aripiprazole (15 mg/ml) in appropriate quantity of oil. The mixture was homogenized and to it, accurately weighed quantity of surfactant: cosurfactant blends was added in small portion with stirring. The blends were mixed thoroughly using magnetic stirrer and to it add dropwise double distilled water with continuous stirring around 10 min. compositions of ARP microemulsion shows in Table 1. 4.…

In the present studies, we have made an attempt to investigate the catalytic activity of as synthesized AuNPs for a model reaction of reduction of 4-NP to 4-AP in the presence of sodium borohydride. The reaction was analyzed by measuring the absorbance of the reaction mixture in the wavelength range of 200-700 nm for fixed time intervals (Fig.8a-b). Initially, the absorption spectra of 4-NP (0.05 mM) showed the absorption peak at…

Synthesis of ZnO Nanostructures ZnO nanoparticles were prepared by using the following reagents : Starch solution Zinc nitrate hexahydrate {Zn〖(NO_3)〗_2 .6 H_2 O} Sodium hydroxide { NaOH) Freshly prepared ammonia solution. In order to prepare 0.01M of ZnO nanoparticles, the following steps were followed: The 0.01 M of Sodium hydroxide { NaOH} solutions in starch was prepared by adding 0.04 gm of NaOH powder dissolved in 100 ml of 3% starch solution. The solutions were stirred for 1…
