Enhanced light-harvesting in quantum dot-metal-organic frameworks

Researchers report the functionalization of porphyrin-based metal-organic frameworks (MOFs) with CdSe/ZnS core/shell quantum dots for the enhancement of light harvesting via energy transfer from the QDs to the MOFs. This work paves the road for the development of efficient light harvesting complexes for solar energy conversion.

Gold Nanorods a whole new way of harvesting solar energy

A new method of harvesting the Sun's energy is emerging, thanks to scientists at UC Santa Barbara's Departments of Chemistry, Chemical Engineering, and Materials. Though still in its infancy, the research promises to convert sunlight into energy using a process based on metals that are more robust than many of the semiconductors used in conventional methods.

Researchers demonstrate fullerene crystals with bimodal pore architectures

Scientists for the first time demonstrated template-free novel mesoporous carbon material: fullerene (C60) crystals with bimodal pore architectures and having highly crystallized framework. Experiments have proven that this novel meso- and macroporous material show better electrochemical performance compared to pristine C60 due to higher electrochemically active surface areas.
