Topic: Summary of research interests and intended research topics

My research experience reaffirms me the significance of energy storage devices to society, strengthening my resolve to develop rechargeable batteries. I am interested in exploring them comprehensively in my doctoral study. New generations of computing and numerous technological systems, aided by the worldwide presence of the internet infrastructure are placing rechargeable batteries as necessities in the society. The increasing demand for energy storage batteries requires the development of rechargeable batteries.
Rechargeable non-aqueous Li-O2 batteries are regarded as promising alternatives to traditional Li-ion batteries due to their ultrahigh theoretical energy density of 3,500 Wh kg-1, which is about 10-fold higher than that of Li-ion batteries. The key issues for Li-O2 batteries are the high charge voltage and the corrosion of Li anode. The high charge voltage is relevant to the O2 evolution reaction (OER) process, where bulky and insulating Li2O2 particles are decomposed. A general method to tackle it is employing the soluble redox mediator (RM) to facilitate the decomposition of Li2O2 particles. In my previous work, I have developed a new bi-functional redox mediator to accelerate the kinetics of ORR and OER, greatly improving the rate performance of Li-O2 batteries. However, the Li-O2 batteries with this RM did not exhibit excellent cycling performance. This is because micron-sized Li2O2 particles formed during ORR process are found to be difficult to decompose during OER process. Thus, although the anion of the RM is of benefit for the oxidation of bulky Li2O2, the charging over-potentials are not effectively decreased. As the cycle proceeds, the over-potentials needed for OER process increases, leading to more side reactions and early fade of Li-O2 batteries. It is necessary for me to replace the anion of this RM with a more effective one to lower the activation energy process, promote the electrochemical decomposition of Li2O2, and reduce the OER over-potentials. Besides, the RM+ could chemically oxidize the Li anode, which would result in the corrosion of the Li anode. Therefore, it is also a critical factor on long-term cycles to protect Li anode. Building a stable protection layer is a delicate strategy to protect Li anode. The combination of RM and protection layer could work synergistically to reduce the over-potentials and side reactions, achieving great cycling performance. Prof. Grey’s specialization in solid-state nuclear magnetic resonance (ssNMR) could be of great help for me to investigate the electrochemistry inside the cells as ssNMR is sensitive to the electrochemical products formed during cycling, such as LiOH and Li2CO3. The formation of insoluble LiOH and Li2CO3 on the Li anode result from side reactions in the Li-O2 batteries. With the clear signatures for these products, I could gain valuable information that assist me to better design RM and protection layer. In conclusion, I intend to open up a path to promote the cycling performance of Li-O2 batteries using ssNMR.

Hi, I have to write a research paper it is a self-study and paper writing assignment in which I have to extent my knowledge of physiological and nutritional aspects of functional food products and place this in the light of safety and health aspects during both manufacturing and consumption of the food. I will upload the description of the assignment please focus on the deliverbales and the assessment rubric, put all the points the teacher wants in the report and make it all merit according to the assessment rubric.

Some important points:

1. Composition of the product and digestion physiology of the functional component.
2. Product (microbial) safety, packaging, and shelf life.
3. Use of minimal processing techniques and product safety.
4. The health benefit of your functionalized product.
5. Sustainability aspects of the product.

Discuss in your paper how minimal processing could be used (or is used) for the manufacturing of your product to achieve the desired properties:
· What is the relation between the use of a minimal processing techniques, shelf life, and safety for the consumer?
· What is the relation with microbial safety, and
how does it affect flavour and nutritional quality of your functional food product?

Description

To explain the difference between Method and Procedure, say you were going to cook some eggs for dinner. The METHOD you would use might be: Cook the eggs in boiling water for 10 minutes in a pot on the stove. The boiling water cooks the eggs by denaturing the proteins in the egg, causing them to become solid and opaque.

The PROCEDURE would be: Obtain a large cooking pot and fill with 2 liters of water. Place on the stove and heat on high until the water reaches 100C and is boiling. Add 4 eggs to the water and stir until the water returns to boiling. Boil for 10 minutes. Place a colander in the sink and pour the egg/water mixture into the colander to separate the water from the eggs. Pour cold water over the eggs to cool them. Peel the eggs and place them in a bowl to serve.

I want you to write the METHOD for the experiment, not the PROCEDURE. Be sure to state what is occurring chemically at each step.
Also they are in this experiment I used vacuum filtration Don’t write about gravity filtration.
