Biologically active compounds from the marine fungus Penicillium dimorphosporum protect cells from paraquat, the highly toxic herbicide with no remedy, and might enhance the action of some drugs. The fungus was isolated from soft coral collected in the South China Sea during an expedition on the Akademik Oparin research vessel. Scientists of Far Eastern Federal University (FEFU) and G. B. Elyakov Pacific Institute of Bioorganic Chemistry reported the results in
Marine Drugs.
Paraquat a herbicide compound highly toxic for animals and humans. About a hundred countries, including the United States, apply it for crop cultivation and weed control. Dozens of countries, including Russia, have banned the poisonous compound. The problem of paraquat harm to people is widely known in India. Farmers who work in the fields risk dying because of getting a dangerous dose of the substance.
Scientists Advance the Technology of High-Speed Sintering for Optical Ceramics
Written by AZoOpticsFeb 5 2021
Scientists of Far Eastern Federal University (FEFU) have advanced the technology of high-speed sintering for optical ceramics (Nd3+:YAG), i.e. active elements generating laser emission in the near-infrared wavelength range (1.06 μm) for cutting the edge microelectronics and medicine. The researchers have managed to reduce significantly the initial nanopowders consolidation period (10 - 100 times) forming a nanostructure with ensured high optical transparency of the ceramic material.

Optical Materials.
Diode-pumped microlasers based on Nd3+:YAG nanoceramics, due to their short lasing pulse duration, high peak power, and beam quality in combination with the elements small size, are relevant for the ranging, telecommunications, space technology, industry, and medicine.
