Safira: "Ubumaji" buhishe mu mabuye y'agaciro agaragara

 Ese wigeze utangazwa n'ubururu bwiza bwa safiro? Iri buye ry'agaciro ritangaje, rihabwa agaciro kubera ubwiza bwaryo, rifite ibanga ry' "imbaraga zikomeye za siyansi" rishobora guhindura ikoranabuhanga. Impinduka ziherutse gukorwa n'abahanga mu bya siyansi b'Abashinwa zafunguye amayobera y'ubushyuhe ahishe ya safiro, atanga amahirwe mashya kuri byose kuva kuri telefoni zigendanwa kugeza ku bushakashatsi mu isanzure.

Kuki Bidashoboka'Safiro Ishonga Mu Bushyuhe Bukabije?

Tekereza ishusho y'ijisho ry'umuzimyamwoto rishyushye cyane mu muriro, ariko rigakomeza kuba ryiza cyane. Ubwo ni ubuhanga bwa safiro. Iyo ubushyuhe burenga 1.500°C—bushyushye kurusha lava yashongeshejwe—iri buye ry'agaciro rigumana imbaraga n'ububengerane bwaryo.

Abahanga mu bya siyansi bo mu kigo cy’ubuhanga mu by’ingufu z’amashanyarazi n’ubuhanga mu by’ikoranabuhanga cya Shanghai mu Bushinwa bakoresheje ubuhanga buhanitse kugira ngo bamenye amabanga yacyo:

• Imiterere ya atomu: Atomu za safira zigira agace ka hexagonal, buri atomu ya aluminiyumu ifunze mu mwanya wayo na atomu enye za ogisijeni. Iyi "kage ya atomu" irwanya ubushyuhe, ifite coefficient yo kwaguka k'ubushyuhe ya just 5.3 × 10⁻⁶/°C (icyakora, zahabu ikura vuba inshuro zigera kuri 10).
• Ubushyuhe butembera mu cyerekezo: Nk’umuhanda ugana mu cyerekezo kimwe, ubushyuhe bunyura muri safiro vuba 10-30% ku buryo bunyura mu mirasire imwe n’imwe ya kristu. Abahanga mu by’imashini bashobora gukoresha ubu buryo bwo gukonjesha bukoresha ikoranabuhanga rigezweho kugira ngo bakore uburyo bwo gukonjesha bukoresha ikoranabuhanga rihanitse cyane.

Ibikoresho bya "Superhero" byageragejwe muri Extreme Laboratory​

Kugira ngo bashyire safiro ku iherezo ryayo, abashakashatsi biganye imiterere mibi y'ikirere cyo hanze n'iguruka rya hypersonic:

• Igereranya ryo Kugaruka kwa Roketi: Idirishya rya safiro rya mm 150 ryarokotse umuriro wa dogere selisiyusi 1,500 mu gihe cy'amasaha menshi, nta mvune cyangwa ngo rigire icyo rihindura.
• Ikizamini cyo kwihangana cya laser: Iyo byatwitswe n'urumuri rwinshi, ibikoresho bya safiro byarambaga kurusha ibikoresho gakondo ku kigero cya 300%, bitewe n'ubushobozi bwabyo bwo gusohora ubushyuhe inshuro eshatu kurusha umuringa.

Kuva ku bitangaza bya laboratwari kugeza ku ikoranabuhanga rya buri munsi

Ushobora kuba usanzwe ufite ikoranabuhanga rya safiro utabizi:

• Ecran zidashishurwa: iPhone za mbere za Apple zakoreshaga lenzi za kamera zikozwe muri safiro (kugeza igihe ibiciro byazamutse).
• Kwandika Kwamunikasiyo: Muri laboratwari, utubuto twa safiro tuba dufite uduce twa quantum twinshi (qubits), tugumana imiterere ya quantum yatwo inshuro 100 kurusha silicon.
• Imodoka zikoresha amashanyarazi: Bateri za EV zikoresha electrode zikozwe muri safiro kugira ngo hirindwe ubushyuhe bwinshi—ibi bihindura umukino ku modoka zitekanye kandi zigenda kure.

Ubushinwa bwateye imbere mu bumenyi bwa Safiro

Nubwo safiro imaze ibinyejana byinshi icukurwa, Ubushinwa burimo kuvugurura ahazaza habwo:

• Amabuye Manini: Laboratwari zo mu Bushinwa ubu zihinga utudomo twa safiro dupima ibiro birenga 100—tunini bihagije kugira ngo twubake indorerwamo zose za telesikope.
• Udushya mu by’ibidukikije: Abashakashatsi barimo gukora safiro ishobora kongera gukoreshwa ikoresheje terefone zishaje, bagabanya ikiguzi cyo kuyikora ho 90%.
• Ubuyobozi bw'Isi Yose: Ubushakashatsi buherutse gukorwa, bwasohotse muIkinyamakuru cy'amakristaro y'ubukorikori, ni ikimenyetso cy’iterambere rikomeye rya kane ry’Ubushinwa mu bikoresho bigezweho muri uyu mwaka.

Ahazaza: Aho Safira Ihurira n'Ubumenyi-Bya siyansi

Bite se niba amadirishya ashobora kwisukura? Cyangwa telefoni zishyushwa n'ubushyuhe bw'umubiri? Abahanga mu bya siyansi barimo kurota cyane:

• Safira yisukura: Uduce duto tw’ibumba dushyirwa muri safiro dushobora kwangiza umwotsi cyangwa umwanda iyo tubonye izuba.
• Ubumaji bw'amashanyarazi: Hindura ubushyuhe bw'imyanda buva mu nganda bugahinduka amashanyarazi ukoresheje imashini zikoresha amashanyarazi za safiro.
• Insinga z'Agasanduku k'IcyumbaNubwo bikiri mu buryo bw'imitekerereze, igipimo cy'imbaraga hagati y'uburemere n'ubunini cya safiro gituma kiba umukandida w'imiterere minini y'ejo hazaza.
