Abstract Biaxial anisotropy, arising from distinct optical responses along the three principal directions, underlies the complex structure of many crystalline, polymeric and biological materials. However, existing techniques such as X-ray diffraction and electron microscopy require specialized facilities or destructive preparation for full three-dimensional information.

Graphene-based thermoelectric materials: Toward sustainable energy-harvesting systems Among sustainable energy-harvesting systems, thermoelectric technology has attracted considerable attention because of its ability to directly convert heat into electricity and diverse applications. Graphene, with its exceptional electrical conductivity and mechanical properties, is a promising candidate for thermoelectric materials.
