#Spinach leaves vibrate to kick off photosynthesis Vibrations deep within spinach leaves enhance the efficiency of photosynthesishe energy conversion process that powers life on our planet.

Nature energy transfer The team breakthrough centered on the electroactive materials. While previous battery designs have used metals or toxic chemicals,

and cellular respiration. hese are the types of molecules that nature uses for energy transfer, Narayan says.

While the new system has a significant advantage in energy conversion efficiency over conventional thermoelectric devices it has a much lower power densityâ##that is the amount of power that can be delivered for a given weight.

but with this design we were able to dramatically improve energy conversion to 37 percent which is comparable to

wire-free energy transfer could be as easy as wireless internet. When Katie Hall saw a light-bulb glowing in the middle of a room with no wires attached she was shocked.

In the house of the future, wire-free energy transfer could be as easy as wireless internet.

This could enable research leading to significant advances in electronics they say as well as a better understanding of natural energy transfer processes such as photosynthesis. The research is described this week in the journal Nature Communications in a paper co-authored by MIT postdocs Gleb

but the energy conversion process involves multiple steps #and it's difficult to isolate the efficiency of each step says Dr. Brendan O'connor an assistant professor of mechanical engineering at NC State and senior author of a paper on the work.

Heterostructured nanoparticles can be used as catalysts and in advanced energy conversion and storage systems. Typically these nanoparticles are created from tiny seeds of one material on top of

The advance not only addresses the problem of dead ends or discontinuous pathways that make for inefficient energy transfer

but it also solves some instability problems where the materials in mixed blends of polymers tend to lose their phase-separated behavior over time degrading energy transfer the polymer chemist says.

This interaction enables the energy transfer between the internalized molecules says Raymo director of the UM laboratory for molecular photonics.

As the energy transfer takes place the acceptors emit a fluorescent signal that can be observed with a microscope.

The next phase of this investigation involves demonstrating that this method can be used to do chemical reactions inside cells instead of energy transfers.
