THz ELECTRONICS. "Terahertz metamaterials are a new class of composite; artificial materials still under development, which interact at terahertz (THz) frequencies. The terahertz frequency range used in materials research is usually defined as 0.1 to 10 THz. This bandwidth is also known as the terahertz gap because it is noticeably underutilized. This is because terahertz waves are electromagnetic waves with frequencies higher than microwaves but lower than infrared radiation and visible light." https://lnkd.in/dD8nSe2 View in LinkedIn

“CHIRALITY IN NATURE is ubiquitous in exquisite examples wherever you look, be it at the molecular, cellular, or organismic level. However, in a biomimetic quest for new materials with new properties, a stumbling block is often the introduction of chirality into a synthetic system, to try to mimick the 60 biomineral materials made by millions of species in nature.” https://lnkd.in/dCa_nDw View in LinkedIn

CELLULOSE CHIRAL LIQUID CRYSTALS (CLC). "Biological materials, such as DNA in human cells, cellulose in plant cell walls, chitin in arthropod' cuticles and collagen in human compact bones, exhibit Bouligand's twisted plywood architecture, which is that of cholesteric liquid crystal." https://lnkd.in/dyyFFsB View in LinkedIn

CHIRAL ASYMMETRIES. "In recent years, even piezoelectric, pyroelectric, and ferroelectric effects in biological materials are the subject of investigations. Pasteur was probably the first to suggest over 100 years ago that biological systems have chiralic dissymmetric properties and that these properties are important for the functioning of biological systems." https://lnkd.in/dHfzDYk View in LinkedIn
