Fitokemija i sonikacija: Ultraefikasna ultrazvučna ekstrakcija biljnog bioaktivnog sadržaja
Fitokemija je znanost o kemijskim spojevima dobivenim iz biljaka - od polifenola, flavonoida i alkaloida do terpena, saponina, glikozida, pigmenata, antioksidansa i sastojaka eteričnih ulja. Ovi fitokemijski spojevi vrijedni su za nutraceutike, farmaceutike, kozmetiku, prehrambene sastojke, prirodne boje, mirise, biljne ekstrakte i…

Sonikacija omogućuje novu razinu kontrole u samoorganizaciji celuloznih nanokristala
, Kathrin HielscherSonication holda the key to unlocking more reliable, scalable production of cellulose nanocrystal (CNC) materials. A new study reveals that sonication doesn’t just break up CNC clusters – it actively reshapes how these sustainable nanomaterials self-assemble into cholesteric liquid crystal structures responsible for brilliant structural color. By observing CNC ordering inside tiny evaporating droplets, researchers found that ultrasound can delay gelation, shift kinetic arrest, and tune the helical pitch evolution with remarkable precision. The findings highlight sonication as an industrially relevant processing lever for programming reproducible CNC-based photonic coatings and advanced bio-based materials at scale.
