Oxygen Atoomikada: guryaha waxtar leh. Waa maxay oxygen qaaradda?

Bal qiyaas rinjiyeynta aad u qaali ah in hareeyeen dab ba'an. midabo qurux badan kaddeedka codsatay in midabo kala duwan, ayaa la waayay hoos lakab oo danbas madow. Waxaa u muuqan lahaa, masterpiece lahagaajin laga badiyay.

sixir sayniska

Laakiin ka quusanina sameeyo. Rinjiyeynta la dhigayaa in qolkii vacuum gudahood oo walax abuuraa ah aan la arki karin, loo yaqaan oxygen qaaradda awood ah. a saacado ama maalmo yar gudahood, si tartiib ah laakiinse hubaal weeraraan caleemaha iyo midabada bilaabaan in ay mar kale ka muuqan. Daboolay daaha cusub ee varnish hufan, rinjiyeynta si ammaantiisii hore ku soo laabtay.

Waa laga yaabaa in ay sixir, laakiin waa sayniska. Habka, horumariyo by saynisyahano xarunta cilmibaadhista Glennovskom (GIZ) NASA isticmaalaa oxygen qaaradda ee daryeel iyo dib u soo celinta shuqullada tahay, taas oo haddii kale waa la soo gasho ay waxyeello lahaa. walax ayaa sidoo kale waa inay awoodaan inay si buuxda u nadiifin implants qalliinka loogu talogalay jidhka bini'aadamka, taas oo si weyn u yaraynaysaa halista ah ee caabuq. Waayo, dadka qaba cudurka macaanka, sida loo hagaajin karo qalab la socodka glucose ah, taas oo kaliya qayb ka mid ah dhiigga looga baahan yahay imtixaanka hore loo baahan yahay in bukaanka xakameeyo kara xaaladda ay ku sugan. walaxda la textured karaa dusha polymer for Amda wanaagsan unugyada lafta, kaas oo fursadaha cusub ee fureysaa in daawada.

Oo waa walax awood badan waxaa laga heli karaa si toos ah uga hawada.

Atoomikada iyo oxygen kelli

Ogsijiin jira dhowr hab oo kala duwan. gaaska ah in aan neefsan yeedhay O _2, in uu yahay, waxay ka kooban tahay laba atamka. Waxaa jira qaaradda oxygen, formula ah kuwaas oo - O (atom). foomka saddexaad ee element kiimikada - O _3. Allena Tani, taas oo, tusaale ahaan, laga helo dhulka jawi sare.

oxygen Atoomikada in xaaladaha dabiiciga ah ee oogada Dhulka muddo dheer ma jiri karaan. Waxay leedahay falcelin ah ay aad u sarayso. Tusaale ahaan, oxygen qaaradda biyo foomamka hydrogenperoxid ah. Laakiin in meel bannaan, halkaas oo ay jiraan xaddi weyn oo shucaaca, Ilaahow ₂ Britain waxaa si fudud la jebiyey si ay u sameeyaan qaab qaaradda. Jawiga kastana falagiisuu dhex Earth hooseeyo at 96% waxay ka kooban tahay ogsijiin qaaradda. Markii waagu beryo ee howlgalka Slaam meel by NASA ee ay joogaan keenaa dhibaatooyin.

Waxyeelada wanaag

Sida laga soo xigtay Bruce Banks, physics sare "Alfaporta" hawlan cilmi deegaanka boos xarunta Glennovskogo ee laanta, ka dib markii diyaaradaha yar oo ka mid ah qalabka Slaam meel ka mid ah dhismaha ugu horeysay u eegay sida haddii ay qariyey dhaxan (waxay waxaa la soo dersay nabaad daran iyo texturing). oxygen Atoomikada sameynayso qalab organic dahaadhay pride si tartiib ah iyaga dhaawac.

GIZ si ay u baaraan sababaha burburka. Sidaas darteed, cilmi ayaa kaliya ma aasaasay hababka ilaalinta pride ka oxygen qaaradda, waxay sidoo kale helay hab si ay u isticmaalaan awood u iman kara burbur ee element this kiimikada lagu hagaajinayo nolosha on Earth.

Nabaad in meel bannaan oo

Marka pride ah waxa dhulka kastana falagiisuu dhex hooseeya (kuwaas oo loo soo bandhigay iyo meesha baabuurta la duuliyo ku salaysan ISS), oxygen qaaradda sameeyey jawiga haraaga ah, fal karaa dusha sare ee pride ah, ku dheehan ay u noqdaan dhaawacan. In saldhigga horumarka, nidaamka awoodda ayaa walaac in xubno batari qoraxda ka polymers sameeyey mari nabaad-degdeg ah ay sabab u tahay tallaabada of oxidizer firfircoon.

galaas dabacsan

NASA ayaa helay xal. Koox Seynis yahanno ka tirsan xarunta Cilmi-baarista Glennovskogo ayaa sameeyay daahan dhuuban-filimka for cadceedda in ay ahaayeen boogeed tallaabo ee element mintid ah. Silica ama galaas, waxaa hore u oxidized, sidaa daraadeed waxa aan la waxyeelayn kara by oxygen qaaradda. Cilmi ayaa abuuray daahan a of galaas silica hufan, waa sidaas oo khafiif ah in ay ahayd dabacsan. lakabka ilaaliya Tani waxaa si adag u hogaansamey guddi cusbi oo ka nabaad ilaaliyo, oo aan dhima mid ka mid ah hantida kaamerada. Caymiska weli waa guul leh ilaalinaya milicsiga ee Space Station caalamiga ah, iyo sidoo kale loo isticmaalay si loo ilaaliyo saldhiga looxaanta ah "Mir".

Sida laga soo xigtay Banks, milicsiga si guul maray in ka badan toban sano joogaan meel.

Faa'iidaysiga xoogga

Ka dib markii boqolaal baaritaano in ay qayb ka yihiin horumarka blaastiigga adkaysi u oxygen qaaradda, koox ka mid ah cilmibaadhe ka tirsan xarunta Cilmi-baarista ee Glennovskogo helay waayo-aragnimo in fahamka sida kiimikada. Khubarada arkay suurtagalnimada ee isticmaalaya xubno kale oo dagaal badan.

Sida laga soo xigtay Banks, kooxda noqday ogsoon tahay isbedelka cusub ee kimistari dusha of nabaad guurka ka mid ah maaddooyinka organic ah. Guryaha ee oxygen qaaradda waa sida in ay tahay awoodaan in ay ka saarto wax organics, shidaalka, taas oo si fudud ma dhaqmayso kiimikada caadiga ah.

Cilmi ayaa helay siyaabo badan oo loo isticmaalo. Waxay barteen in ogsijiin ah qaaradda jirsado dusha silicone ee galaaska, kaas oo noqon kara mid waxtar leh haddii aad la abuuro qaybaha wax shaabad lagu hermetic iyaga oo aan dusin midba midka kale. Nidaamkan waxaa loogu talagalay dhagixiina way Space Station Caalamiga ah. Intaa waxaa dheer, saynisyahano ku ogaaday in ogsijiin ah qaaradda celin karo iyo sii wadida shuqullada dhaawacmay tahay, in la hagaajiyo qalabka dhismaha ee diyaaradaha, iyo sidoo kale in ay ka faa'iideystaan dadka sida waxa loo isticmaali karaa in noocyo kala duwan oo codsiyo Biomedical.

Kamaradaha iyo qalab la qaadi karo

Waxaa jira siyaabo kala duwan oo saamayn of ogsijiin qaaradda dushiisa. Qolladaheeda vacuum inta badan la isticmaalo. Waxa ay size kala duwan sanduuqyada kabaha ka hor inta rakibaadda 1.2 x 1.8 x 0.9 m. By isticmaalaya microwave ama inta jeer ee radio shucaaca ₂ O taagoo waxaa la jebiyey state of ogsijiin qaaradda. qolkii la saaray tijaabada ah ee heerka nabaad polymer taas oo muujinaysaa fiirsashada oo ah walaxda firfircoon gudaha unugga.

Hab kale oo ka mid ah codsanaya walax waa qalab la qaadan karo in u ogolaanaya in ay si toos ah durdur cidhiidhi ah ee oxidant in ay bartilmaameed u gaar ah. abuuri karaa batari socodka sida awood u daboolaya aag aad u ballaaran of dusha loola dhaqmo.

Sida cilmi baaris dheeraad ah tiro sii kordhaysa oo warshado waa xiiso isticmaalka oxygen qaaradda. NASA ayaa abaabulay noocyo kala duwan oo iskaashi, mashaariic u wada iyo shuraakada, oo kiisaska intooda badan waxay noqdeen kuwo guul goobaha ganacsiga kala duwan.

oxygen Atoomikada jidhka

codsiyada Research ee element ku kiimikada aan ku koobnayn meel bannaan oo dibadda ah. oxygen Atoomikada, guryaha waxtar leh waxaa loo aqoonsaday, laakiin si ka badan waa in la sahamiyey, helay codsiyada badan oo caafimaad.

Waxa loo isticmaalaa texturing dusha sare ee polymers oo iyaga ka dhigaa inay awoodaan inay u wada koraan leh lafta. polymers waxaa inta badan si kada ah unugyada lafta laakiin element kiimikaad ahaan firfircoon abuuraa Amda texture-qaadidda. Tani waxay keenaysaa in lacagta kale, kaas oo keenaya oxygen ee qaaradda - daaweynta cudurada nidaamka muruqyada.

oxidizer Tani waxay sidoo kale loo isticmaali karaa in ka implants qalliinka bayoloji firfircoon ka saari nijaasta ahaa. Xitaa dhaqanka hadda ee nadiifiye ah dusha sare ee implants noqon kartaa wax adag in meesha laga saaro oo dhan raad unugyada bakteeriyada, loo yaqaan endotoxins. Kuwani walxaha organic, laakiin aan ku nool, si jeermiska ma waa awoodaa inuu iyaga ka saar. Endotoxins keeni kartaa barar of the-galinta post, oo waa sabab weyn oo dhibaatooyin xanuun iyo ka iman kara in bukaanka qaba galaha aasaasay.

oxygen Atoomikada, guryaha waxtar leh taas oo ka dhigi waxaa suurto gal ah si aad u nadiifiso sanaaci ah oo dhan ka saaraan raad qalabka organic, aad bay u yareeyo halista caabuq post-operative. Tani waxay keenaysaa in horumar laga gaaray natiijooyinka hawlgalka iyo yareynta xanuunka ee bukaanka.

Relief dadka sonkorowga qaba

technology waxaa sidoo kale loo isticmaalaa in ka dareemayaal of glucose iyo kormeerayaasha kale ee caafimaad iyo noolaha. Waxay codsan fiiloyin indhaha looxa, oxygen qaaradda textured. daaweyn Tani waxay u ogolaaneysaa fiiloyin in ay shaandhayso soo baxay unugyada dhiigga cas, jidaynayey serum xiriir wax ku ool ah oo la monitor Satlaytaka kiimikada ka kooban.

Sida laga soo xigtay Miller, Sharon, injineer korontada ee Waaxda deegaanka bannaan iyo tijaabo xarunta cilmi Glennovskogo NASA, waxa ay taasi imtixaanka badan oo sax ah, iyo waqti isku mid ah si loo cabbiro imtixaanka sonkorta dhiigga looga baahan yahay mugga aad u yar oo dhiig ah. Waxaad ka heli kartaa kubad meel kasta oo jidhka ah iyo si aad u hesho qadar ku filan oo dhiig ah si loo ogaado heerka sonkorta.

Hab kale oo ay u helaan ogsijiin qaaradda - hydrogenperoxid ah. Waxaa aad u sii weynaaday oxidizer a badan kelli. Tan waxa u sabab istareexsan wixii decomposes waxaay sheegayaan. oxygen Atoomikada sameeyey by this, hawl badan tamar badan kelli. Tani waxaa keena iyo wax ku ool ah codsiga oo hydrogenperoxid ah, burburinta taagoo of formaldehyde iyo sheyga.

dib u soo celinta

Marka shaqada ka mid ah tahay halis burburka karin in meesha laga saaro sunta organic oxygen qaaradda waxaa loo isticmaali karaa, taasoo ka tago hannaanka wax dhawrsan. Geedi socodka ka saaraysaa oo dhan wax organic sida carbon ama danbas, laakiin inta badan saameyn ah kuma laha rinjiga. Pigments guud ahaan waxay leeyihiin asal ahaan ka imanba iyo mar horeba oxidized, oo taasi ka dhigan tahay in aanay dhaawici doontaa ogsijiin ah. formaldehyde Organic ayaa sidoo kale lagu kaydin karaa waqti-gaadhista count taxadir. maro waa mid amaan ah, maxaa yeelay oksijiin qaaradda waa in xiriir oo kaliya dusha sare ee rinjiyeynta ah.

shuqullada tahay waxaa la geeyaa qolkii vacuum ah oo oxidant waxaa la aasaasay. Iyadoo ku xiran tahay xaddiga burburka gaaray in sawirka laga yaabaa in ay jiraan sii muddo 20 ilaa 400 oo saacadood. Waayo, daaweynta gaarka ah ee aagga dhaawacan u baahan dib u soo celinta, waxa ay sidoo kale waxaa loo isticmaali karaa durdur oxygen qaaradda. Tani waxay tiraa baahida loo qabo in meel farshaxanka ee qolkii vacuum ah.

Danbas iyo lipstick - dhibaato ah ma

Matxafka, galleries iyo kaniisadaha waxay bilaabeen inay soo xiriir GIZ ah, si loo badbaadiyo iyo soo celinta shuqulladoodu farshaxanka. Xarunta Cilmi-baarista ayaa soo bandhigay awood u leh inay soo celiyaan rinjiyeynta ku dhaawacmay Jackson Pollock, ka saar lipstick la farshaxankiisa Endi Uorhola iyo waxyeeleeyeen kaniisad shiraac qiiq ah St. Stanislaus ee Cleveland badbaadiyo. Kooxda Glennovskogo Xarunta Cilmi isticmaalo oxygen ee qaaradda si loo soo celiyo jab waxaa loo arkaa badiyay - qarniyo jir ah nuqul Talyaani ee Raphael ee "Madonna kursiga", tirsan St. Alban ee Episcopal Church ee Cleveland ..

Sida laga soo xigtay Banks, element this kiimikada waa mid aad wax ku ool ah. In dib u soo celinta tahay ay u shaqayso wanaagsan. Si kastaba ha ahaatee, tani ma ahan wax aad ka iibsan kartaa dhalo, laakiin si ka badan wax ku ool ah ay tahay.

Studies mustaqbalka

NASA ku salaysan-celin ah si ay u kala duwan ee daneeyayaasha in ogsijiin ah qaaradda shaqeeyaan. Glennovsky Xarunta Cilmi adeegta shakhsiyaad, kuwaas oo aad u qaali shuqullada tahay ayaa ay saameeyeen dabka guriga, iyo sidoo kale shirkadaha, doondoonay suuragalnimada in la isticmaalayo qalab this ee codsiyada Biomedical sida LightPointe Medical ee Eden Prairie, Minnesota. Shirkadda ayaa laga helay isticmaalka badan ee oxygen qaaradda oo doonaya in la helo xitaa ka sii badan.

Sida laga soo xigtay Banks, waxaa jiray meelo badan oo sahamin. Waxaa la helay tiro badan oo ah codsiyada technology bannaan, laakiin malaha badan oo dheeraad ah oo ku dhuunta ka baxsan farsamooyinka bannaan.

Space in hawshii nin

Koox Seynis yahanno ayaa rajeynaya in ay sii wadaan si ay u sahamiyaan jidadka isticmaalaya oxygen ee qaaradda, iyo sidoo kale kuwa hore u helay rajo. teknoolajiyada badan ayaa la xiranayo, iyo kooxda GIZ rajeynayo in shirkadda shatiga doonaa laguna ganacsi qaar iyaga ka mid ah, in Dadka soo dejin doonaa faa'iidooyinka iyo xataa more.

Under shuruudo gaar ah, ogsijiin ah qaaradda keeni karaa dhaawac. Thanks to cilmi NASA, walax tani waxaa hadda kaalin togan si sahaminta meel , iyo nolosha on Earth. Haddii ay tahay ilaalinta ee shuqullada aad u qaali ah tahay ama caafimaadka dadka, oxygen qaaradda waa aalad awood. Shaqaynta isaga la waa abaal boqol, iyo natiijooyinka ay yihiin isla markiiba la arki karo.
