Summary Draft 2

The web page “How an accidental discovery made this year could change the world” from BIGTHINK (The Future, 2022) introduces the possibility of using the lithium-sulfur battery. Lithium ion batteries can be used to power most electronic devices or machinery.

Nonetheless, they are extremely toxic to vast ecosystems, have lifecycle problems from repeated charging, battery degradation which meant higher cost required for battery replacement, cumbersome for lightweight applications and it being flammable which led Drexel scientist's to look into Lithium sulfur batteries.     

The lithium-sulfur battery eliminates the above issues. However, it only has half the charging cycle of lithium-ion batteries.

To allow lithium sulfur batteries to last longer, Drexel scientists accidental discovery of a chemical phase of sulfur known as monoclinic gamma-phase sulfur prevents battery degradation.

Compared to lithium-ion batteries, lithium-sulfur batteries last two times longer, have three times more energy storage, charge equally fast, reduce battery expansion, are safer, and cheaper. Although scientists have not fully understood the phase of sulfur for practical usage. With all these advantages over lithium-ion batteries, lithium-sulfur batteries can be used for more applications such as aerospace and marine sectors to achieve low carbon goals in the near future.

Descriptive Reflection: Self-introduction Letter

 Dear Prof Brad Franklin Blackstone, My name is Chin Leon and I am writing this email to introduce myself to you as a student from your class Critical Thinking and Communication group S7. I am currently a year 1 student in Singapore Institute of Technology, majoring in Mechanical Design and Manufacturing Engineering. My interest in engineering dates back to when I was in secondary school where I excelled in math and physics as I really love numbers. Whenever I see a machine like a plane or a car I am curious as to how it functions. I, therefore, began researching math and calculation-based courses. I landed in Aeronautical Engineering at Singapore Polytechnic where I learnt the aerodynamics and how the plane is able to fly up in the sky. I was offered the opportunity to intern at an aerospace company and spoke to many of the engineers there, to learn about the different parts, and how they looked and functioned. All of this has greatly motivated me to pursue a career in engineering...

The importance of Communication skills

“Communication skills are an essential component in the education of engineering students to facilitate not just students’ education but also to prepare them for their future careers.” Communication skills are essential, engineers in addition to doing the scope of their work will also have to be involved in other roles such as managing a team to even doing sales. Their job will require them to communicate with people of different groups such as clients, co-workers, and their superiors to provide a clear solution to them which involves them doing a proper presentation or even writing a clear and detailed report. Thus, engineering students should start picking up communication skills before stepping into the workforce.

Summary Reader Response (Revised)

The web page “How an accidental discovery made this year could change the world” from BIGTHINK (Lockett, 2022) introduces the possibility of replacing our current choice of lithium-ion batteries with lithium-sulfur batteries due to their advantages. According to Lockett (2022) lithium-ion batteries have lifecycle problems from repeated charging, and battery degradation, which means a higher cost is required for battery replacement, and when mined, the materials are extremely harmful to the environment discharging toxic chemicals. Lithium-sulfur batteries are an improvement on the above issues but have only half the charging cycle of lithium-ion batteries (Lockett, 2022). However, Drexel scientists’ recent discovery of monoclinic gamma-phase sulfur, although not fully understood to be put into practical use, prevents battery degradation in lithium-sulfur batteries altogether (Lockett, 2022). Compared to lithium-ion batteries, lithium-sulfur batteries last two times longer, have three ti...
