Artificial cells, or liposomes, are a promising area in biotechnology and nanotechnology, and now they have a new power source. An experimental finding has revealed a new method for converting light to stored chemical energy within the cells.
A team headed by Arizona State University chemistry professors Thomas Moore and Devens Gust has developed a light-powered molecular pump that shuttles calcium ions through a phospholipid membrane – calcium ion pumping that resembles various key cellular activities in living organisms, but engineered to be powered by light through specially designed molecules.
The research is reported in the November 28 issue of the journal Nature by Ira M. Bennett, Hebe M. Vanegas Farfano, Federica Bogani, Alex Primak, Paul A. Liddell, Ana L. Moore, Thomas A. Moore and Gust from Arizona State University and Luis Otero, Leonides Sereno and Juana J. Silber from Universidad National de Rio Cuarto in Argentina.

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.
Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
Empa researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range – and they are unrivalled in terms of weight.
Electric motors and electronic devices generate electromagnetic fields that sometimes have to be shielded in order not to affect neighboring electronic...

With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams. Thanks to a special evaluation method based on artificial intelligence (AI), the detection process is completed in just 70 milliseconds.
Laser welding is a process suitable for joining metals and thermoplastics. It has become particularly well established in highly automated production, for...
