Nanocellulose bụ akụ kacha baa ọgaranya n'ụwa. Ọ nwere uru nke nbibi dị mfe, mmeghari ohuru, adịghị egbu egbu, ọnụ ala ma dịkwa mfe ịnweta, a na -atụkwa anya na ọ ga -edochi akụrụngwa mmanụ ala ọdịnala wee jiri ya wepụta ngwa ọrụ dị iche iche dị elu nwere nnukwu uru. Dị ka usoro nkwadebe na isi mmalite nke nanocellulose, nanocellulose nwere ike kewaa ụzọ atọ: nanocrystalline cellulose (CNC), cellulose nanocellulose (CNF) na cellulose nje (BC).




Ọgụgụ 1. Isi mmalite, microstructure na ngwa nwere ike nke nanocellulose



Nanocellulose ihe eji arụ ọrụ maka photonics chiral
Chirality juru ebe niile na -arụ ọrụ dị mkpa na sayensị ndụ na sayensị ihe. CNC bụ ihe nanometer chiral photonic crystal material. Ọdịdị chiral nematic liquid crystal phase nke CNC enweghị ike iji ya kwadebe ihe nkiri ihe eji arụ ọrụ nwere akụrụngwa dị elu yana ngwa anya pụrụ iche., mana a ga -ejikwa ya dị ka ụdị ndebiri nro dị nro iji kpalite nanoparticles iji mepụta ihe arụ ọrụ nwere usoro chiral. Ya mere, catalysis chiral, ụdị chiral metamaterials, izo ezo polarization na biosensing nwere uru ngwa dị mkpa.



Ọgụgụ 2. Ngwa nke nanocellulose ihe na -arụ ọrụ na photonics chiral
