Masayendisiti eNRNU MEPhI adzidza mashandisirwo eplasma inotonhora mu biomedicine. Vaongorori veNRNU MEPhI, pamwe nevamwe vavo vanobva kune dzimwe nzvimbo dzesainzi, vari kuferefeta mukana wekushandisa plasma inotonhora pakuongorora nekurapa zvirwere zvebhakitiriya nemavhairasi uye kuporesa maronda. Kuvandudzwa uku kuchava hwaro hwekugadzirwa kwezvishandiso zvekurapa zvetekinoroji yepamusoro. Maplasma anotonhora muunganidzwa kana kuyerera kwezvikamu zvinochajwa zvinowanzove zvisina magetsi uye zvine tembiricha yakaderera yeatomu ne ionic, semuenzaniso, pedyo netembiricha yemumba. Panguva iyi, tembiricha inonzi electron, inoenderana nedanho rekumutsa kana ionization yemhando dzeplasma, inogona kusvika zviuru zvemadhigirii.
Mhedzisiro yeplasma inotonhora inogona kushandiswa mukurapa - semushonga wepamusoro, haina njodzi mumuviri wemunhu. Akataura kuti kana zvichidikanwa, plasma inotonhora inogona kugadzira oxidation yakakosha munzvimbo, senge cauterization, uye mune dzimwe nzira, inogona kukonzera nzira dzekuporesa dzinodzoreredza. Makemikari asina ma free radicals anogona kushandiswa kushanda zvakananga pamusoro peganda rakavhurika nemaronda, kuburikidza nemajeti eplasma anogadzirwa nemachubhu eplasma akagadziriswa, kana zvisina kunanga nemamorekuru anonakidza ezvakatipoteredza akadai semhepo. Panguva iyi, torch yeplasma pakutanga inoshandisa kuyerera kushoma kwegasi risina kuchengetedzeka zvachose -heliyamu or argon, uye simba rekupisa rinogadzirwa rinogona kudzorwa kubva payuniti imwe chete kusvika kumakumi emawatts.
Basa iri rakashandisa plasma yakavhurika yemhepo, iyo masayendisiti anga achigadzira zvinhu zvakawanda mumakore achangopfuura. Kuyerera kwegasi kunoenderera mberi pakumanikidzwa kwemhepo kunogona kuiswa maion ukuwo kuchiitwa kuti kubviswe kure, kubva pamamirimita mashoma kusvika pamasendimita makumi, kuti kusvitse huwandu hwezvinhu zvisina kusimba hwakaiswa maion kudzika kunodiwa kune imwe nzvimbo yaunoda (semuenzaniso, nzvimbo yeganda remurwere).
Viktor Tymoshenko akasimbisa kuti: “Tinoshandisaheliyamusegasi guru, rinoita kuti tideredze maitiro e oxidation asingadiwe. Kusiyana nekufambira mberi kwakafanana muRussia nekune dzimwe nyika, mumarambi eplasma atinoshandisa, kugadzirwa kwe helium plasma inotonhora hakufambiswi nekuumbwa kwe ozone, asi panguva imwe chete kunopa mhedzisiro yekurapa yakajeka uye inodzoreka.” Vachishandisa nzira iyi itsva, masayendisiti anotarisira kurapa zvirwere zvebhakitiriya zvakanyanya. Sekureva kwavo, kurapwa kwe plasma inotonhora kunogonawo kubvisa kusvibiswa kwehutachiona nekukurumidza kuporesa maronda. Zvinotarisirwa kuti mune ramangwana, nerubatsiro rwenzira itsva, zvichave zvichikwanisika kurapa zvirwere zvegomarara. “Nhasi tiri kungotaura nezvemhedzisiro yepamusoro-soro, nezvekushandiswa kwepamuviri. Mune ramangwana, tekinoroji iyi inogona kugadzirwa kuti ipinde mukati memuviri, semuenzaniso kuburikidza nehurongwa hwekufema. Kusvika pari zvino, tiri kuita bvunzo dze in vitro, apo plasma yedu kana jet inosangana zvakananga nehuwandu hushoma hwemvura kana zvimwe zvinhu zvemhando yehupenyu,” akadaro mutungamiri wechikwata chesainzi.
