Neqymium, udub dhexaadka 60 ee miiska xilliyeed.
Neydeysmium wuxuu la xiriiraa Praseymium, oo labaduba lanthanide-ka leh guryaha aad u lamid ah. Sannadkii 1885, ka dib markii farmasiilaha iswiidhishka ee Modudo ay ogaadeen isku dar ahLanthanumiyo praseymmium iyo nexymium, Austriancyach Welsbach waxay si guul leh u kala soocaan laba nooc oo ah "Dhul dhif": nedoysmium oxide iyopraseidymium okide, ugu dambeyntiina waa la kala saarayneqymiumiyopraseyfiumiyaga ka yimid.
Neydeysmium, bir cad oo bir ah oo leh astaamo kiimikaad oo firfircoon, si dhakhso ah u oksidi kartaa hawada; La mid ah prsoidmium, si tartiib ah ayey uga falcelisaa biyo qabow si dhakhso lehna waxay si dhakhso leh ugu siidaayaan gaaska hydrogen-ka biyaha kulul. Neydeysmium waxay ku leedahay wax yar oo hooseysa qolofkiisa dhulka oo inta badan ku jirta Monazit iyo Bastnasite, oo ay ku jiraan tiro labaad oo keliya girdium.
Neyyyrium waxaa inta badan loo isticmaalaa midab midab leh galaas qarnigii 19aad. Markaneqymium okideWaxaa lagu dhalleeceeyay galaas, waxay soo saari lahayd hadhno kala duwan oo u dhexeeya casaan diiran ilaa buluug iyada oo ku xidhan ilaha iftiinka ee deegaanka. Ha iloobin dhalada qaaska ah ee ionymium ionsmium oo loogu yeedhay "galaas neodeysmium". Waa "Qalbi" ee lass, iyo tayadeeda si toos ah u go'aamiya suurtagalnimada iyo tayada tamarta wax soo saarka ee qalabka. Waxaa hadda loo yaqaanaa in laser uu ka shaqeeyo dhexdhexaadka dhulka ee soo saari kara tamarta ugu badan. Muraayadaha neyyodymium-ka ee galaaska nexymium-ka ayaa fure u ah in kor loo qaado oo hoos u dhaca "scyscraper" ee heerarka tamarta ee ugu badan inta lagu gudajiro heerka ugu badan ee kala-guurka, kaas oo kor u qaadi kara heerka tamarta dayaca ee Nanojoule 10-9 laser tamar ah heerka "qorraxda yar. Qalabka Glass ee ugu weyn ee Dunida ee ugu weyn ee Dunida, aaladda dabka qaranka ee Mareykanka, ayaa kor u qaaday tikniyoolajiyadda joogtada ah ee tikniyoolajiyadda joogtada ah ee galaaska cusub oo lagu taxan yahay toddobada yaab ee teknolojiyada ee dalka. Sanadkii 1964, machadka 'Shanghai Machadka Hoptics iyo makaanikada Shanghais ee Akademiga Science-ka Shiinaha ayaa bilaabay cilmi-baarista afarta tikniyoolajiyadda aasaasiga ah ee muhiimka ah, edbinta iyo tijaabinta galaaska neyyodymium. Tobannaan sano oo sahamin ah, horumar weyn ayaa ugu dambeyntii la sameeyay tobankii sano ee la soo dhaafay. Kooxda Hu Lini ayaa ah kan ugu horreeya ee adduunka ee lagu xaqiijinayo Shanghai Ultra si adag iyo aaladda gaagaaban ee loo yaqaan '' ' Xooggeedu waa in la baro tikniyoolajiyadda muhiimka ah ee tikniyoolajiyadda ballaaran iyo kan-sare ee waxqabadka muraayadda ee laser-ka ee laseed. Sidaa darteed, akadeemiyada Shiinaha ee cilmiga Shiinaha ee machadka 'Eptics Shanghai' ee machadka Shanghai iyo mashiinada saxda ahi waxay noqdeen hay'addii ugu horreysay ee adduunka ka madaxbanaan tikniyoolajiyadda wax soo saarka oo buuxa ee qaybaha muraayadaha indhaha ee laser.
Neydeysmium sidoo kale waxaa loo isticmaali karaa in lagu sameeyo magnet joogto ah ee ugu awoodda badan - nedoymium birta birta alloy. Newsymoum birta boron ee birta alloy waxay ahayd abaalmarin culus oo ay bixisay Japan sanadkii 1980-yadii si ay ugu jebiyaan hal-ku-biirinta General Motors ee Mareykanka. Aqoonyahan casri ah Saynisyahanada Shiinaha ayaa sidoo kale abuuray hab ku meelgaar ah oo cusub, iyadoo la adeegsanayo kululaynta kululaynta halkii ay ka noqon lahaayeen cufnaanta dembiga iyo kuleylka ee magnetka, oo gaabin kara wareegga wax soo saarka ee magnetka, oo gaabinaya wareegga wax soo saarka.
