As scientists create molecular complexes to perform increasingly minute operations -- such as molecular level switches or memory devices -- it is critical that the association forces that hold the molecular components together be accurately understood.
But measurements of association constants are often not accurate, according to an article by Virginia Tech Ph.D. student Jason Jones and chemistry professor Harry W. Gibson, published in May 15, 2003 online issue of the Journal of the American Chemical Society ("Ion Pairing and Host-Guest Complexation in Low Dielectrict Constant Solvents," scheduled for print on June 25, 2003).
Designing molecules that switch on and off or that attach to a material to transport it and then release it at some external signal, requires a complexation (or connection) process that is reversible. Fine control of reversible complexation processes requires precise understanding of the attractive forces that hold two or more molecules together in the supramolecular assembly.

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...
