Scientific and educational software



Until recently the perception was that scientific knowledge has to be implemented in mathematical form. Now, just as the pen became the routine tool, so does the computer. It demands an even stronger version of definition of knowledge. The scientific knowledge becomes useful only when represented by a software application.

Here is a showcase of intellectual life products. Some of them are valuable enough to put price tag on them itself. Others are to produce traffic and advertisement monetization.

Our products are commercial software.
Forum includes articles of paradoxical and controversial content as well just thinking about matters of current interest.
The software archive in some way is a just a demonstration of abilities to code web staff.
Trade places looks like not attract enough attention without massive investments in advertisement and most possible will be closed and transformed into theft store of intellectual property.
Crystallization is the passion and soon will be addition of main achievement that are universal formulas of kinetic of the crystal growth.
Guestbook is transferring into combination of comments to any page at LeoKrut. If at one page there is no ability to comment it will come soon.
Album will be the store of pictures.
Management is about Dr. Leonid Sakharov who is the key person of LeoKrut.

Dr. Leonid Sakharov
Lead developer and co-founder.

Dr. Leonid Sakharov has more than 25 years of experience in scientific research and development of multidisciplinary technology processes.

Before the move into a business of production of scientific software applications Dr. Sakharov performed as a scientific programmer/algorithms developer one year in Admetric BioChem Inc. and five years earlier in Northeastern University. There were innovative research projects in the areas of improving of revealing compounds from mass spectrometer files and predictive analysis of time series.

Twenty years of researches in Russia Academy of Science in Saint Petersburg (Physical Technical Institute, Mechanical Engineering Institute, Institute of Silicate Chemistry) gave to Dr. Sakharov extraordinary expertise in areas of fine ceramic materials technology and deep theoretical understanding of fundamentals of these processes on nanoscale/molecular level.
