The story of how it took one 23-year-old engineer a day to remake swimming masks into medical
It has been a month since the Peoples’ Friendship University of Russia joined the #мейкерыпротивковид (makers against Covid) movement and has been helping doctors and patients with 3D printing. Engineer Mark Dyachenko from the Center for Additive and Foreign Technologies of RUDN University used a 3D-printer to print 1,149 adapters for mask filters, which are used by doctors in more than 15 hospitals in Moscow.

At the beginning of the epidemic, when medical institutions faced a shortage of personal protective equipment in the “red zone”, in Italy they came up with a technology how to make a medical mask for doctors from a swimming mask. Decathlon company was ready to give diving masks to hospitals. However, to use these masks, it was necessary to attach a special filter requiring an adapter. At the same time, the masks were of different models each needing specially designed additional parts.

Regular manufacturing would have been long and expensive, because first it would have taken producing molds for thermoplastic machines for each part and each machine separately. RUDN University Institute of Innovative Engineering Technologies (IIIT) proposed using additive, SLS (selective laser sintering) technologies and printing parts on Farsoon SS403P industrial 3D printers (Prodways x 4500).

It took RUDN Additive and Edge Technologies Center just one day to launch the production of adapters of the required parameters from certified medical plastic. Work included setting the task for the 3D printer, printing and cooling of the parts themselves, extracting and cleaning. In a day, 400 adapters of the required parameters were printed, and after two days, the Blokhin Cancer Center and the Mukhin City Clinical Hospital received the first batches of adapters and got effective and comfortable masks. Since most employees are in lockdown, part of the industrial design and logistics work was done remotely. The entire production was performed by only one engineer-technologist of the Center —a 23-year-old Mark Dyachenko!

"We began to print adapters for diving masks when it became clear that doctors lacked personal respiratory tract protective equipment. The adapter is installed on the top of the mask, to which 1 or 2 filters are attached. Each printing round makes 400 adapters, as soon as I took out the printed parts, I immediately prepared and started a new print. While the machine was printing parts, I cleaned the finished product. To print adapters, we used special medical plastic, absolutely harmless to the human body. Due to lockdown the work became more complicated, but we were always in touch with colleagues using messengers. I know that the doctors were grateful to us, and the page of one of the charitable organizations had a post with photos of our adapters and a mention of my name" - Mark Dyachenko, engineer-technologist at RUDN Additive and Edge Technologies Center.

Now RUDN has already manufactured 1,149 filter adapters for 3 mask models. Every seventh swimming mask in Russia, has become a mask for the doctors’ protection thanks to the 3D production of the Peoples’ Friendship University of Russia. They are used in 15 medical institutions in Moscow and the Moscow region.

Engineers at the Institute of Innovative Engineering Technologies at RUDN University have begun manufacturing face shields fasteners and hose holders for lung ventilators — 290 holders are already made. University experts continue experiments to improve enhanced protection medical masks.

Reference:

During one month more than 15 medical institutions in Moscow and the Moscow Region received masks with filters adapters manufactured by RUDN University:

  • A. Vishnevsky hospital
  • Meditsina JSC (Academician Roytberg’s Clinic)
  • O.Mukhin Clinical Hospital
  • M.Vladimirsky hospital
  • I.Davydovsky State Clinical Hospital No. 23
  • State Clinical Hospital No. 52
  • N.Bauman State Clinical Hospital № 29
  • V.Veresaev State Clinical Hospital No. 81
  • Hospital for War Veterans No. 2
  • Hospital for War Veterans No. 3
  • Mozhaisk Central District Hospital
  • N. Blokhin Cancer Center
  • A.Vishnevsky Surgery Hospital
  • Center for Family Planning and Reproduction
  • Russian Railways Central Clinical Hospital

RUDN soil scientists developed a new method for assessing soil fertility

RUDN soil scientists have revealed a direct correlation between the rate of soil formation of carbon dioxide, called CO2 emissions, and the content of microbial biomass in it. It is known that CO2 emission from soil is mainly conditioned by respiration of soil microorganisms and plant roots. The more CO2 soil emits, the more microbial biomass it usually contains. It was shown that CO2 emission by chernozem of different ecosystems (or different types of land use) correlates with the content of microbial biomass, and most closely with the rate of its microbial respiration. And the soil with good microbial properties has the “best quality”, is more fertile, provides the highest yield of crops and other plant biomass.

RUDN University chemists proposed a way to reduce three times the temperature for the oxidation of alkanes

RUDN University chemists and their colleagues from the Russian Academy of Sciences have proposed new catalysts that allow to reduce the temperature of the oxidation reaction of alkanes three times — from 150 to 50 degrees. This significantly reduces the cost of synthesizing alcohols, aldehydes and other compounds needed, in particular, for the production of nylon and capron.
