A solar battery operation is based on the light getting on the photosensitive surface characterised with a “redundancy” of electrons, the latter start shifting into the next in-depth layer of the battery made of “electron-poor” materials. The electromotive force occurs which leads to the emergence of electric current. In fact the two layers interact as electrodes of a regular battery.
Search for materials fit to make solar batteries is of great interest for researchers. Materials…Continue
Researchers at the A.N. Nesmeyanov Institute of Heteroorganic Compounds, Russian Academy of Sciences, are developing catalyst systems, which will be implemented by the biggest European pharmaceutical companies and will probably lead to changes in industrial standards for vitamin and drug production. These systems are supposed to help in increasing pharmacologic composites purity and in decreasing the final output cost. The effort is being…Continue

When people are born no spare parts are readily available for them. Soft tissue regeneration occurs quite fast but what about bone recovery? It was proved that implants — artificial bone replacements — were in use as long ago as some time BC. A piece of a mandibula of an Inca (6th century BC) was found in modern Honduras, around the De Los Muertos plateau, bearing three dental implants made of sea mussel shells. A female skull belonging to the 1st century BC, with a…Continue

The country needs special — synthetic specialists — supermen with the “nano-“ prefix. To this end, pupils at school should be already taught new technologies. The opinion was expressed by Doctor of Engineering, Director General of the Close Joint-Stock Company “Concern ‘Nanoindustry’”, Mikhail Ananian.…Continue
