UJGu Demertri Budke uNjingalwazi uHu Yunan uneyunithi yebhetri kunye nesixhobo sokulinganisa imeko yentlawulo. Ibhetri etshajwayo ngundoqo wobugcisa obuninzi obutsha, umzekelo, ukusetyenziswa okutsha kwamandla avuselelekayo. Ngokweenkcukacha ezingakumbi, zisetyenziselwa izithuthi zombane, iifowuni eziphathwayo kunye neelaptops.

I-German Meizi Johnnes Gitten Fort University (JGU) kunye ne-Simo Himhumholz Research Institute (HIM) bacebise indlela yokungaqhagamshelwa ukuvavanya imeko yokutshaja kunye nasiphi na isiphene seebhetri ze-lithium-ion. Ukuza kuthi ga ngoku, i-atomic magnetometer isetyenziselwa ukulinganisa indawo yemagnethi ejikeleze iyunithi yebhetri. Unjingalwazi uDmitryBudker kunye neqela lakhe bahlala besebenzisa iindlela zemagnethi zeathom ukufunda iingxaki ezisisiseko zefiziksi, ezinjengokukhangela amasuntswana amatsha.

Igeyiji yemagnethi isetyenziselwa ukuchaza amagama alinganiswa ngomlinganiselo wemagnethi. Umzekelo olula wekhampasi kukuba umgangatho osulelekileyo wekhampasi emhlabeni usebenzisa umgangatho ongaqhagamshelwanga webhetri yemagnetometer ye-athomu ukuqinisekisa ukuba imfuno yeebhetri ezinkulu ezinokutshajwa ngoko ke imalunga nokumiselwa kobuchwephesha bokuxilongwa obuchanekileyo nobuchanekileyo bebhetri. Uphuhliso oluninzi olutsha luya kuxhomekeka ekubeni lunokusetyenzwa na ukuze lubonelele ngesakhono esaneleyo kunye nobomi obude.

UGqr. I-ARNEWITNBROCK, iQela eliSebenzayo, unjingalwazi uDmitryBudker, iJGU Physics, uthe: “Ukuqinisekiswa komgangatho weebhetri ezitshajwayo ngumceli mngeni omkhulu. Iindlela ezingaqhagamshelwanga zinokunika inkuthazo entsha yokuphucula umgangatho webhetri.

"Uphando lweHelmhoz. Iqela laqhekeza ngokusebenzisa imagnetometer yeathom. Lo mbono ucetywayo kwinkomfa yenkomfa phakathi kukaBudker kunye noNgxa wakhe weYunivesithi yaseNew York u-Alexejerschow.

"Itekhnoloji yethu iyafana nomgaqo wokusebenza kwemagnethi, kodwa ilula kuba sisebenzisa imagnetometer yeathom", utshilo uWickenbrock weqela lolu phononongo. Imagnetometer yeathom yimagnetometer yempompo yokukhanya esebenzisa iathom yegesi njengeprobe yendawo kazibuthe. Zifumaneka ngokurhweba, kwaye zisetyenziselwa ukusetyenziswa kwimizi-mveliso kunye nophando olusisiseko.

Iqela le-Budker le-JGU kunye ne-HIM liye laphuhlisa isivamvo sayo esiphezulu semagneti, kwaye basebenzisa ezi magnetisms ze-athom kuphando olusisiseko lwefiziksi, njengokukhangela izinto ezimnyama, kunye nokuzama ukuphatha amaqhina kwizinto kunye nezinto ezichasayo. nitshabalalisane ngoko nangoko. Indlela elula inokuqonda imilinganiselo ekhawulezayo kunye nephezulu kwimeko yokulinganisa ibhetri, beka ibhetri kwindawo yangasemva yemagnethi.

Ibhetri iya kutshintsha indawo yangasemva kazibuthe kwaye ilinganise utshintsho kwimagnetometer yeathom. UWickenbrock wongeze wathi: “Olu tshintsho lusinika ulwazi malunga nokutshaja ibhetri, amandla ashiyekileyo kunye nomonakalo onokwenzeka. "Le nkqubo ikhawuleza kakhulu, sicinga ukuba inokudityaniswa ngokulula kwinkqubo yomatshini.

". "Iingxelo ezikhatywayo malunga nokuqhuma komsi we-elektroniki kunye nokulimala okulinganiselweyo kwiintlobo ezithile zeefowuni eziphathwayo eziphethe ezinye iintlobo zeefowuni eziphathwayo, ukuvavanya iziphene kwibhetri. Umbhali ubonisa kwiphepha elikufutshane le-PNAS: "Ubuchule bokuxilonga obu buchwepheshe kulindeleke ukuba buvavanye iiseli ngexesha lophando, ulawulo lomgangatho okanye ukusebenza.

"Kwihlobo elidlulileyo, iQela eliSebenzayo elifanayo liququzelele imisebenzi emibini enxulumene nokusebenzisa iiathom kunye nefiziksi yenyukliya, ngokuthatha inxaxheba kwinqanaba eliphezulu lamazwe ngamazwe. Malunga nama-200 abaphandi abavela kwihlabathi liphela baphendule umlinganiselo wamandla weathom yangoku kunye nezinye iindlela zemiba yetekhnoloji yokulinganisa ubungakanani. .
