Cucurbituril-Functionalized Nanocomposite as a Promising Industrial Adsorbent for Rapid Cationic Dye Removal.

A supramolecular cucurbit[6]uril (CB[6])-enriched magnetic montmorillonite (CBCM) nanocomposite was prepared and characterized. CB[6] played a prominent role as a capping agent, helping in better distribution of the nanoparticles, and as a binder between nanoparticles. Montmorillonite provided structural stability and fortified ultrafast adsorption toward dyes.

Nested seaweed cellulose fiber deposited with cuprous oxide nanorods for antimicrobial activity.

Bird's nest type architectural network of cellulosic nanofibers was extracted, with nearly 34% yield, from green filamentous seaweed Chaetomorpha antennina using mild bleaching agent. Nanorods of cuprous oxide (CuO) were grown over the porous sheet, prepared from the seaweed cellulose, by one step hydrothermal method. The seaweed cellulose and CuO nanorods deposited seaweed cellulose sheets, were characterized by XRD, SEM-EDX, FT-IR, TGA and tensile test.

Zinc oxide nanorod clusters deposited seaweed cellulose sheet for antimicrobial activity.

Seaweed cellulose was isolated from green seaweed Ulva fasciata using a common bleaching agent. Sheet containing porous mesh was prepared from the extracted seaweed crystalline cellulose along with zinc oxide (ZnO) nanorod clusters grown over the sheet by single step hydrothermal method. Seaweed cellulose and zinc oxide nanorod clusters deposited seaweed cellulose sheet was characterized by FT-IR, XRD, TGA, and SEM-EDX.
