CLASSIFICATION OF MATERIALS (METALS , CERAMICS AND POLYMERS COMPOSITES) {ONLINE CLASS} LECTURE 1

Summary

In this lesson, Humpted Shannon discusses advanced materials, such as biomaterials, semiconductors, and smart materials, emphasizing their importance and properties. The instructor highlights the need to master these concepts, particularly for exams and quizzes, as they are frequently tested. A quick recap of concepts from previous chemistry courses is provided, with a focus on materials' properties. Towards the end, the instructor mentions upcoming paid courses, noting that starting next week, only those who have made payments will receive the course links. The session concludes with an invitation for students to join future lessons.

Takeaways

• 😀 The lesson covers the topic of advanced materials, including polymers, ceramics, biomaterials, and smart materials.
• 😀 Polymers are long chains of molecules, categorized as either thermosetting or thermoplastic based on their heat sensitivity.
• 😀 Ceramics are inorganic materials known for their durability and heat resistance, often used in high-temperature applications.
• 😀 Biomaterials are materials designed to interact with biological systems, like semiconductors and artificial bones.
• 😀 Smart materials respond to external stimuli, and their properties can change in response to specific environmental factors.
• 😀 Understanding the properties of different materials is crucial, as they are frequently tested in quizzes and exams.
• 😀 Many of the material properties covered in the lesson were revisited from previous courses like grade 12 and first-year chemistry.
• 😀 The speaker emphasizes the importance of mastering material properties to excel in future assessments, including tests, quizzes, and final exams.
• 😀 The course also provides access to additional lessons for a fee, offering 100 questions per month for $100.
• 😀 The speaker encourages students to review the provided slides and notes to reinforce their understanding of material properties.
• 😀 Starting next week, lessons will be restricted to paid participants, with free access offered for the current week.

Q & A

What are biomaterials, and how are they related to advanced materials?

Biomaterials are substances that have been designed for use in medical or biological applications. Some of them are made from advanced materials like semiconductors and smart materials, which are engineered to interact with biological systems in a specific way.

What types of materials did the speaker mention during the lesson?

The speaker mentioned semiconductors, artificial biomaterials (like parts of bones), and smart materials as examples of materials covered in the lesson.

Why is it important to understand the properties of materials?

Understanding the properties of materials is crucial because it helps in answering questions related to tests, quizzes, and exams. The speaker emphasizes that these properties are often tested and need to be mastered for academic success.

Which subjects or courses covered the properties of materials before this lesson?

The properties of materials were covered in Grade 12 and in first-year chemistry courses, especially in relation to polymers and other materials like ceramics.

What is the speaker's approach to delivering lessons in this course?

The speaker is focusing on reviewing material quickly and ensuring students understand the properties of various materials. They are offering lessons in a structured way, with a focus on revisiting key topics to prepare for exams.

Why did the speaker rush through some slides in the lesson?

The speaker rushed through some slides because they were primarily providing notes, which students can later review on their own. The goal was to cover the material efficiently and focus on key points.

What additional support did the speaker offer to students during the lesson?

The speaker mentioned that they would send the lesson slides to students, giving them the opportunity to go over the material in more detail on their own. They also assured students that further explanations would be provided during future lessons.

What did the speaker emphasize regarding tests, quizzes, and final exams?

The speaker emphasized that questions about the properties of materials are common in tests, quizzes, and final exams, so students must understand these properties thoroughly to perform well.

What is the speaker's payment structure for continued lessons?

The speaker charges 100 questions per month for lessons. However, they are offering lessons for free during the current week. Starting next week, they will restrict access to only those who have paid.

How can students contact the speaker to make payments for continued lessons?

Students can contact the speaker using the contact details displayed on the screen to make their payments and continue attending lessons.
