Researchers from St. Petersburg have invented a way to check the viability of grains and seeds of agricultural plants without prior germination. The scientists assume that injuries of the germ and tissues of seeds can be revealed through X-ray photomicrography with the help of computer recognition system. This methodology allows determining the quality of wheat, barley, oats, rye and other crops seed grain.
The yield of agricultural cultures depends on viability and quality of seed grain. Researchers from the Agrophysical Research Institute, Russian Agricultural Academy (St. Petersburg) M.V. Arkhipov, L.P. Gusakova and D. I. Alekseyeva have developed a computer system to reveal nonviable and defective grains and seeds without prior germination.
The X-rays photograph is taken of seeds or grain. The photographs show the breaks of integrity of the corn seed storage tissue and defects of the germ. They can be caused by different reasons - mechanical load while transporting and storage, bacterial or mycosis infection, or vermin. The seeds often perish because of losing the germ - the germ can be knocked out in harvesting or can be eaten out by insects. The researchers have made reference images of each defect to compare X-ray photographs of the seeds with them.

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...
