Mau oyamba:Kutalikitsa mphamvu pakati pa mankhwala olondola ndi kufufuza kwakuya kwa danga
Neodymium oxide (Nd₂O₃), zinthu zanzeru mudziko losowabanja, ndiye mafuta pachimake cha okhazikika maginito kusintha. Kuchokera pamagalimoto oyendetsa magalimoto amagetsi a Tesla kupita ku masensa olondola kwambiri a Mars rovers, mphamvu ya maginito yomwe imayikidwa mu kapangidwe kake ka maselo ndikukonzanso malingaliro amphamvu, azachipatala ndi azamlengalenga pamlingo wofunikira padziko lonse lapansi wa 12% pachaka. Pofika 2025, kukula kwa msika wapadziko lonse wadutsa madola mabiliyoni a 4.7, China, Australia ndi nkhondo ya mchere ya Brazil, idzadziwitsa mwachindunji ndondomeko ya mbadwo wotsatira wa kusintha kwa sayansi.
Kukhazikika kwa kapangidwe ka mamolekyu kuzimitsidwa pa 2270 ° C
Rose-red makhiristo aneodymium oxidewonetsani zinthu zodabwitsa pansi pamikhalidwe yovuta kwambiri.
- Maginito mphamvu revolution: The galasi munda kugawa mphamvu kufika 1900cm, kupereka NdFeB maginito mankhwala mphamvu zoposa 52MGOe.
- Thermodynamic Fortress: Kutha kwake kukhalabe osavunda pa 2270 ° C mumlengalenga wa nayitrojeni kumapangitsa kuti ikhale yotchinga yoteteza yosankha pazofufuza zakuzama zamlengalenga.
- Lupanga lakuthwa konsekonse kwa chilengedwe: pang'onopang'ono hydrolysis pa pH> 9, kuyendetsa bwino kwambiri muukadaulo wobwezeretsanso - NanoMagnetics Laboratories ku United States yakwanitsa 92% kukonzanso zinyalala zamafakitale.
Kuchokera pa pacemaker mpaka ma fusion reactors: mapu amitundu inayi a ntchito
1. Nkhondo yokhazikika ya maginito hegemony
NdFeB maginito kutenga 78% ya msika okhazikika maginito msika, aliyense 3MW mphepo chopangira magetsi ayenera kudya matani 2.3 wa okusayidi neodymium. Hitachi Metals yaku Japan idapanga njira ya HDDR, kukakamiza kwa maginito kudakwera mpaka 35kOe, kulimbikitsa kutsogola kwa sitima ya maglev 600km / h.
2. Kusintha kwatsopano kosungirako mphamvu
Zida za cathode za Neodymium-doped LiCoO₂ zidalumpha kuchuluka kwa mphamvu zamabatire a lithiamu-ion ndi 27%. Mu batire ya Tesla 4680 paketi,neodymium oxideimagwira ntchito ngati chothandizira njira zoyendera ma elekitironi, kukakamiza kuthamanga kwa mphindi 15.
3. Matikiti a nthawi ya quantum
Mu makina oziziritsa a IBM quantum kompyuta, kutsika kwamafuta otsika kwambiri a neodymium oxide (0.8W/mK@4K) kumatsimikizira kukhazikika kwa ma bits mu 0.015K chilengedwe.
Geopolitics ndi Green Paradox: Ice ndi Moto mu Global Supply Chains
Lamba wa neodymium ku DRC amawongolera 62% yazinthu zoyambirira zapadziko lonse lapansi, koma ukadaulo woyenga umayendetsedwa ndi China (89% ya ma patent). Dipatimenti ya US Department of Energy's Rare Earths Strategy 2030 ikufuna kuti chiwonjezeko cha 300% cha mphamvu yakukonza kwanuko, pomwe EU's Carbon Boundary Assessment Method (CBAM) ikukakamiza makampani kuwerengeranso mapazi awo a kaboni kuchokera ku mgodi kupita ku chomera cha maginito.
Nkhondo Yam'tsogolo: Makhiristo Opangira ndi Biomining mu Nkhondo ya Breaking Ground
1. Njira zamakono zosokoneza
- Ce₂Fe14B single crystal yolimidwa ku JASRI Synchrotron Radiation Center ku Japan yapeza 83% ya mphamvu yamaginito yamagetsi a neodymium.
- Mapuloteni a maginito omwe amachotsedwa m'nyanja yakuya yamadzi otentha archaea, kuzindikira bioconcentration ya ma ion a neodymium kutentha ndi kupanikizika.
2. Equation yokhazikika
Ukadaulo wa plasma atomic layer deposition (PE-ALD) wopangidwa ndi Fraunhofer Institute ku Germany umayang'anira makulidwe a zokutira za neodymium oxide pamlingo wa 3.2 nm ndikuwonjezera kuchuluka kwa zinthu zomwe zimagwiritsidwa ntchito mpaka 99.8%.
pa
Pamene mgodi wa Mount Weld ku Australia udatengera maloboti opindulitsa a AI, mpweya wotulutsa mpweya pa toni ya neodymium oxide unatsika ndi 42% - kodi izi zikuwonetsa kusintha kwapadziko lapansi komwe kumayendetsedwa ndi algorithm? Pansi pa zofuna zapawiri za quantum computing ndi kuphatikizika koyendetsedwa, mtengo waluso wa neodymium oxide waposa zitsulo zamtundu wakale, ndipo wakhala chizindikiro chachikulu chaulamuliro wadziko lonse wasayansi ndiukadaulo.
Kuti mupeze zitsanzo zaulele za zinthu zapadziko lapansi kapena kudziwa zambiri za zinthu zomwe sapezeka padziko lapansi, landirani kuLumikizanani nafe
