In their article the Bioinformaticists listed the experimentally calculated hematocrit values of a total of 57 species of vertebrates from the literature. “However there are some aberrations from the optimum,“ Stark points out. The hematocrit of seals for instance is considerably higher with 63 percent. “Additional criteria might apply in this case.“ Marine mammals for instance need a bigger capacity to store oxygen as they dive for long periods of time.With their results the Jena scientists also question the illegal practice of blood doping in sports: This means trying to raise the concentration of the oxygen transporting hemoglobin in the blood and thereby trying to increase the athlete’s performance. This leads to an artificial increase of the hematocrit value. “This is not only a criminal offence, but at the same time its physiological effect is highly questionable according to our calculations“, Prof. Schuster summarizes.

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...
