Sample interview questions: How do you approach the design and synthesis of materials with controlled porosity or surface properties?
Sample answer:
Design and Synthesis of Materials with Controlled Porosity or Surface Properties
-
Define target properties: Identify the desired porosity (size, shape, distribution), surface area, and surface functionalization for the application.
-
Select appropriate precursor materials: Consider the chemical composition, morphology, and porosity characteristics of potential precursors.
-
Design synthetic routes: Develop tailored synthesis protocols that control the nucleation, growth, and assembly of the material. Techniques may include sol-gel processing, templating, self-assembly, and chemical vapor deposition.
-
Control processing parameters: Optimize temperature, pressure, reaction time, and the use of catalysts or surfactants to fine-tune the porosity and surface properties.
-
Utilize characterization techniques: Employ advanced characterization methods (e.g., X-ray diffraction, scanning electron microscopy, gas adsorption analysis… Read full answer
