Novgorod scientist proposed digging the metro with an innovative knife

Metro builders can start digging metro tunnels with an innovative knife from Novgorod scientists.

A model of an improved machine for laying underground communications was proposed by the Novgorod scientist Shodmon Nozirzoda.

The item will be 15-45% smaller, but will also increase the reliability of the construction of metro tunnels and communications under standing buildings.

Industry-specific enterprises have already shown interest in the innovation and may begin to use it in the near future.

One of the key unsolved problems in the creation of the ITER thermonuclear reactor is the choice of material for the inner wall of the reactor facing the hot plasma.

Specialists from the RARMA company (Lipetsk), the Rosatom Institute in Troitsk and the National Research Nuclear University MEPhI proposed a solution - diffusion saturation of the tungsten surface (the main material of the walls) with boron atoms.

Microcracks arising from thermal loads are “healed” due to the melting of boron oxides with the formation of a glassy phase.

Comparative tests have shown a significant improvement in the performance of borated-coated tungsten compared to conventional tungsten.

By changing the energy of the particles, scientists can “scan” a sample from the surface to a depth of several tens of microns—as if conducting tomography at the nanoscale.

In addition to research, PASTekh will become a training base for training engineers in the field of accelerator and cryogenic technology - rare but critically important specialties.

At the Laboratory of Nuclear Reactions (FLNR), experiments are already underway on the synthesis of the 119th element, which should become the first in the eighth period of the table.

Particular attention is paid to radiation safety: FLNR is modernizing the “superheavy element factory” in order to obtain permission to work with materials of hazard class I.

A laboratory study examined the effects of curcumin and resveratrol on G361 melanoma cell lines and healthy melanocytes.

The most pronounced effect was recorded when both components were used simultaneously for 48 hours.

Under the influence of this combination, during the specified period, a sharp decrease in the survival of tumor cells and a significant drop in the level of ATP were observed, which indicates a critical disruption of their energy metabolism.

At the same time, healthy skin cells were affected to a much lesser extent.
