We create long polymer nanotubes by directly pulling on the membrane of polymersomes using either optical tweezers or a micropipette. The polymersomes are composed of amphiphilic diblock copolymers, and the nanotubes formed have an aqueous core connected to the aqueous interior of the polymersome. We stabilize the pulled nanotubes by subsequent chemical cross-linking. The cross-linked nanotubes...

The ligand-to-metal charge transfer in gold nanoclusters gets influenced by the interacting lipid that regulates photoinduced electron aqueous medium.

A study on room temperature Suzuki cross-coupling in an aqueous medium was carried out using a simple hydrophilic palladium (II) complex, trans-PdCl2(NH2CH2COOH)2 as catalyst in the presence of K2CO3 in air. This approach with a comparatively inexpensive and hydrophilic catalyst, mild reaction condition and aqueous media exhibits excellent catalytic activity towards the Suzuki coupling of aryl ...

Seed mediated aqueous chemical growth (ACG) route was used for the growth of ZnO nanostructures on Si substrate in four different growth mediums. The growth medium has shown to affect the morphology and the size of the different nanostructures. We observed that the medium containing zinc nitrate anions yields the nanorods, in a medium containing zinc acetate anions nano-candles are obtained. Wh...

The different species formed when gaseous formaldehyde is dissolved in aqueous medium are investigated by a l3C NM R flow-through technique and the spectra of commercial aqueous form­ aldehyde solutions containing methanol com pletely interpreted. I3C H ,0 was used to study the crosslinking reaction with gelatin which leads to methylene and oxym ethylene bridges between gelatin-amino-groups. On...
