(Phys.org) -- Even alternative energy technologies can sometimes be a little greener, according to a Kansas State University graduate student's research.
Artificially structured metamaterials may boost wireless power transfer
Scientists calculate that a "perfect lens," a slab of artificial material engineered to focus electromagnetic fields in ways that natural materials can't, may increase the efficiency of some wireless power transfer systems.
The joy of cheques
An electronic cheque which eliminates the need for costly processing by banks but preserves the simplicity and ease of a traditional cheque book has been designed by a team of academics in the UK.
'Dark plasmons' transmit energy
Microscopic channels of gold nanoparticles have the ability to transmit electromagnetic energy that starts as light and propagates via "dark plasmons," according to researchers at Rice University.
Fluorescent probes increase understanding of bacterium's electron transfer
