André Guinier

André Guinier was a French physicist renowned for his work in studying the structure of materials at a microscopic level. He developed techniques, such as Guinier analysis, which use X-ray or neutron scattering to determine the size and shape of tiny particles or clusters within a substance. This helps scientists understand materials like minerals, metals, or biological samples better. His contributions are fundamental in materials science and chemistry, providing tools to analyze nanometer-scale structures that influence a material’s properties and behavior.
