Dhawaan, machadka farsamada ee akadeemiyada Shiinaha ee sayniska ayaa iskaashi la yeeshay cilmi-baarayaal guriga iyo dibedda ah si ay u sameeyaan horumar cusub oo ka hortagga dhalooyinka galka ah ee galaas aad u dhalanteed ah oo ku jira qiyaasta caadiga ah ee metallical. Natiijooyinka la xidhiidha waxaa cinwaan looga dhigayaa Ultrafiast Cutubyada cadhada tacliinta ah ee mucjisooyinka macdanta ah oo lagu daabaco murqo, oo lagu daabacay horumarka sayniska (sayniska horumarka 5: Eaweey6249 (2019)).
Qalabka quraaradda metatar ah ayaa leh u janjeera inay u roon tahay gaboobay oo isdaba-joog ah oo loogu talagalay Squilibribrium Squilibrium, isla mar ahaantaana, waxaa weheliya iyada oo sii xumaanaysa guryaha aaladda. Si kastaba ha noqotee, iyada oo loo marayo soo-jeedinta tamarta dibadda, sheyga galaaska gabowga ah ayaa dib u soo noolayn kara qaab-dhismeedka (dib u soo noqoshada). Nidaamkan ka-hortagga gabowga ee hal gacantu waxay gacan ka geysataa fahamka aasaasiga ah ee dhaqanka adag ee dhalada ee dhalada, dhinaca kale sidoo kale waa u qalma arrinta arjiga injineerka ee qalabka dhalada. Sanadihii la soo dhaafay, agabyada dhalada macdanta leh ee leh qaabab codsi oo ballaaran, taxane qaabab qaab dhismeed qaab dhismeed ah oo ku saleysan dhakhaatiirta aan shahaadada ahayn ayaa loo soo jeediyay si wax ku ool ah si wax ku ool ah loo xakameeyo farsamooyinka farsamada iyo jirka ee agabka. Si kastaba ha noqotee, dhammaan hababkii dib-u-noolaashaha hore waxay ku shaqeeyaan heerarka walaaca hoose waxayna u baahan yihiin cabir waqti dheer ah, sidaa darteedna waxay leeyihiin xaddidyo waaweyn.
Cilmi baadhayaashu ku saleysan yihiin tikniyoolajiyadda saameynta ee loo yaqaan 'Plate Plate' ee Qalabka Gaaska ee Iftiinka ah, ayaa ogaatay in muraayadda macdanta caadiga ah ee khafiifka ah ee zircium-ka ay si dhakhso leh ugu soo nooshahay illaa 365 milyan oo nanoseconds (hal milyan oo ay tahay waqtiga ay u qaadato qof inuu isha ku hayo). Endalpy aad ayuu u dhibaataysan yahay. Caqabadda tikniyoolajiyaddan ayaa ah in lagu dabaqo dhowr xamuul oo gpa-garaaca ah iyo ku-meel-gaar ah oo si toos ah loogu soo dejinayo dhalada macdanta, si looga fogaado fashilka firfircoon ee agabyada iyo xargaha xiirashada; Isla mar ahaantaana, adoo xakameynaya xawaaraha ku habboon ee xaashiyaha, birta dib-u-cusboonaysiinta degdegga ah ee dhalada dhalada "ayaa qaboojiya" heerar kala duwan.
Cilmi baadhayaashu waxay ku sameeyeen daraasad dhameystiran habka loo yaqaan 'ultra' ee galaas soonka ah ee dhalada ah ee ka timaadda aragtida heerkulka heerkulka, ka-fikirka ah ", oo muujinaya in dib-u-soo-nooleynta qaab-dhismeedka dhalada uu ka yimaado kooxaha nano-cabir. Mugga bilaashka ah ee uu sababay habka "wareegga xiirashada". Iyada oo ku saleysan habkan jirka, lambarka deborah-ka-qabad-daadashada ayaa la qeexaa, kaas oo sharxaya suurtagalnimada waqtiga qiyaasta waqtiga loo yaqaan 'ultra--gedher rcention' ee dhalada metallic. Shaqadani waxay kordhisay qiyaasta waqtiga loogu talagalay dib-u-habeynta qaabdhismeedka muraayadaha macdanta ee ugu yaraan 10 amar oo baaxad weyn, oo ballaariyay qaybaha arjiga ee sheyga noocan ah, oo ay si qoto dheer u fahmaan fahamka firfircoon ee dhalada.
