Copper Oxide–Cobalt Oxide Nanoscale Heterostructures for Photocatalysis

Shi W., Chopra N., The University of Alabama, US

The research work discussed here will be focused on development of multifunctional nanoscale heterostructured photocatalysts comprised of oxides of copper and cobalt. Two fabrication approaches are described: a) solution and b) dry processing route. The [...]

Carbon nanotubes-metal nanoparticle heterostructures embedded within stimuli-responsive hydrogel for controlled delivery applications

Shi W., Venkatanarayanan A., Chopra N., The University of Alabama, US

In this work we report a novel hybrid hydrogel by embedded complex carbon nanotube-metal nanoparticle architectures within a hydrogel network. This leads to a novel triggering mechanism for release of multiple chemical species at controlled [...]

Gold Nanoparticles Encapsulated within Graphene Shells

Shi W., Chopra N., The University of Alabama, US

We report here a novel approach to fabricate graphene shell encapsulated Au nanoparticles in a chemical vapor deposition process. In addition, processing parameters were studied to result in best quality non-turbostratic graphene shells. This system [...]

Development of a Magnetically Triggered Drug Delivery System using Thermoresponsive Grafted Polymer Networks with Magnetic Nanoparticles

Ankareddi I., Hampel M.L., Sewell M.K., Kim D-H., The University of Alabama, US

A thermosensitive grafted polymeric system which can be triggered to release the loaded drug with an increase in temperature, induced by a magnetic thermal heating event (Brazel et al., 2006) was developed. The desirable carrier [...]
