Sample interview questions: How do you approach designing experiments to investigate the mechanical or electrical properties of inorganic materials?
Sample answer:
Approaches to Designing Experiments for Inorganic Material Properties
-
Define experimental goals and parameters: Clearly articulate the specific mechanical or electrical properties to be investigated, ensuring that the experimental setup can measure these parameters accurately.
-
Select appropriate materials and techniques: Determine the inorganic materials of interest based on their properties, availability, and compatibility with the chosen measurement techniques. Identify suitable methods for sample preparation, characterization, and testing.
-
Control experimental conditions: Establish standardized experimental conditions to ensure reproducibility and minimize external influences. Control factors such as temperature, pressure, humidity, and sample size.
-
Utilize appropriate instrumentation: Employ robust and calibrated instrumentation capable of measuring the mechanical or electrical properties with desired accuracy and precision. Choose equipment specific to the materials and properties under investigation, such as testing machines, impedance spectroscopes, or scanning probe microscopy.
