Radiation Resistant MicrochipsWestern Sanctions Help RussiaCritical ComponentsTwo years ago experts lamented the poor state of the Russian microelectronics sector, which practically had no microchips resistant to space radiation. This situation has been rectified thanks to the tight deadlines to modernize the Russian satellite system, which must be updated in tandem with developments for land-based technologies such as telecommunications systems. "The production cycle of development, design and launch in chip production for space industries is at least two years, and that is why the government decided on the use of a foreign electronic component base," said Aryshev.

Why the EU should ban sf6 gas

What Is Sulfr hexafluoride? and How Is It used?Is Sulfr hexafluoride A Danger to Human Health?How Environmentally Damaging Is It?Has The Environmental Impact Even Been Underestimated?Is The Mitigation of Sulfr hexafluoride Emissions Difficult? Do Better Solutions Exist?Conclusioninsulating gas is a long-lived, highly potent greenhouse gas. It is manmade and combines excellent electrical properties with chemical stability and low toxicity. Moreover, It’s non-flammable and low in cost. These characteristics have led to its widespread and enthusiastic adoption by the electrical industry, which uses approximately 80% of all Sulfr hexafluorideproduced (Powell, 2002: 6). Within the electrical industry sf 6is used as an insulating medium for medium (MV) and high (HV) voltage electrical switchgear. A switchgear is the combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate sections of electrical grids. Low-voltage (LV) switchgear are used for controlling electrical circuits within buildings, medium voltage (MV) switchgear for controlling the electrical grids within cities and towns, and high voltage (HV) switchgear for grids that span a greater geographical area such as countries and regions.
