DEGRADATION OF SYNTHETIC ORGANIC DYES IN SOLUTION BY FERRATE – HYPOCHLORITE OR CALCIUM HYPOCHLORITE [PDF]

open access: yesINVESTIGACION & DESARROLLO, 2017
This study investigated the use of ferrate – hypochlorite solution or solid Ca(OCl)2 as treatment options to remove color and COD from solutions of the synthetic organic dyes: Reactive blue 19, Allura red and Reactive black 5. It was found that doses around 1000 ppm Ca(OCl)2 had color removal efficiencies around 90 % for all the dyes after 15 minutes ...

From Grave to Cradle: Kombucha Waste for Sustainable Electronics

open access: yesAdvanced Science, EarlyView.
This study introduces a sustainable method to purify kombucha bacterial cellulose (KBC) with sodium bicarbonate and hydrogen peroxide, avoiding harsh chemicals. KBC films are patterned with gold and function as pressure sensors for flatfoot gait detection. At the end‐of‐life, the KBC‐based device biodegrades in soil, leaving environmentally benign gold

Nanocellulose–MOF‐Derived Carbon Hybrid Aerogels with Hierarchical Micro/Nanostructures for Solar‐Driven Water Evaporation

open access: yesAdvanced Science, EarlyView.
A biodegradable, cellulose‐based bilayer solar evaporator is fabricated entirely via aqueous, sequential ice‐templating. The hybrid structure combines vertically aligned cellulose nanofibers for rapid water transport with a metal‐orgnic framework (MOF)‐derived porous carbon layer decorated with plasmonic nanoparticles for enhanced photothermal ...
