Sample interview questions: Can you explain the concept of celestial navigation to someone with limited mathematical or scientific knowledge?

Sample answer:

Can you explain the concept of celestial navigation to someone with limited mathematical or scientific knowledge?

Celestial navigation is the practice of determining one’s position on Earth by observing the positions of celestial bodies, such as the sun, moon, and stars. It has been used for centuries by sailors and explorers to navigate the open ocean, and is still used today as a backup to modern navigation systems.

To understand celestial navigation, you need to know a few basic concepts:

• The celestial sphere is an imaginary sphere that surrouns the Earth. The celestial bodies appear to move across this sphere as the Earth rotates.
• The horizon is the line that divides the celestial sphere into two hemispheres: the visible hemisphere and the invisible hemisphere.
• The zenith is the point directly overhead on the celestial sphere.
• The nadir is the point directly opposite the zenith, on the celestial sphere.

To determine your position using celestial navigation, you need to measure the altitude of a celestial body above the horizon… Read full answer

Sample interview questions: How do you approach problem-solving in your work as a materials scientist?

Sample answer:

As a materials scientist, my approach to problem-solving involves a systematic and well-structured process. Firstly, I thoroughly analyze the problem at hand to ensure a complete understanding of its nature and scope. This often involves reviewing existing literature, experimental data, and any relevant theories or models.

Once I have a clear understanding of the problem, I proceed to formulate hypotheses or potential explanations for the phenomena observed. These hypotheses are based on my knowledge of the underlying physics and chemistry of materials, as well as my understanding of the specific properties and behavior of the materials involved.

To test these hypotheses, I design and carry out experiments or simulations, depending on the nature of the problem. This requires careful planning and consideration of the most appropriate techniques and methodologies. I ensure that the experiments are accurately controlled, and the data collected is reliable and reproducible.

After collecting the data, I analyze it using statistical methods and various analytical techniques. This allows me to identify patterns, correlations, and trends that can help validate or refine my hypotheses. If necessary, I may also collaborate with other experts or consult additional resources to gain further insights.

Once I have a solid understanding of the problem and its potential solutions, I develop a detailed plan for further investigation or experimentation. This plan may involve modifying experimental paramete… Read full answer

Sample interview questions: Can you discuss your familiarity with the challenges and opportunities of using polymers in membrane-based processes?

Sample answer:

Can you discuss your research interests with the challenges and opportunities of using polymers in membrane-based processes?

Polymers offer a unique combination of properties that make them ideal for use in membrane-based processes. These properties include:

• Permeability: Polymers can be tailored to have the desired permeability for a given application. This is important for controlling the flux of molecules through the membrane.
• Selectivity: Polymers can be made to be selective for certain molecules over others. This is important for applications such as water purification and gas separation.
• Durability: Polymers are generally durable and can withstand the harsh conditions often encountered in membrane-based processes. This is important for long-term operation of the membrane.
• Cost-effectiveness: Polymers are relatively inexpensive to produce, which makes them a cost-effective option for membrane-based processes.

Challenges:

Despite the advantages of using polymers in membrane-based processes, there are also some challenges that need to be addressed. These challenges include:

• Membrane fouling: Membrane fouling occurs when foreign particles accumulate on the membrane surface, blocking the flow of molecules. This can lead to a decrease in the membrane’s performance over time.
• Membrane degradation: Membrane degradation occurs when the membrane material is damaged by exposure to harsh conditions, such as high temperatures or strong acids and bases. This can also lead to a decrease in the membrane’s performance over time.
• Membrane cost: While polymers are generally inexpensive to produce, the cost of fabricating a membrane can be high. This is due to the need for specialized equipment and the complex m… Read full answer
