Masayendisiti anowana magineti nanopowder ye6Gunhu reGunhu
Nhau idzi - masayendisiti ekunyama akagadzira nzira yekukurumidza yekugadzira Epsilon yesimbi yesimbi uye yakaratidza vimbiso yayo nekuda kwemidziyo yekutaurirana inotevera. Zvivakwa zvakatsanangurwa zvemagineti zvinoita kuti ive imwe yezvinhu zvakachengetedzwa kwazvo, zvakadai sekusvika kwechizvarwa chinotungamirwa chechiratidzo chekutaurirana uye nekuregerera kwemagineti. Basa racho rakabudiswa mubhuku rezvishandiso chemistry c, chinyorwa chedzinza rehumambo hweMEMISTRI. Dare oxide (III) ndeimwe yemhando yakanyanya yakanyanya pasi pano. Iyo inonyanya kuwanikwa seye mineral hematite (kana alpha iron oxide, αpha oxide, αpha oxide, αpha oxoo3). Imwe yakagadzikana uye yakajairika shanduko ndeye maghisheni (kana Gamma shanduko, γ-fe2o3). Iyo yekutanga inoshandiswa zvakanyanya mune indasitiri seyakagwinya pigment, uye yekupedzisira seyemagineti yekurekodha yepakati. Izvo zviviri zvekugadziridzwa zvinosiyana kwete muCrystalline chimiro (alpha-iron oxide ine hexagonil synony uye Gamma-esimbi oxidee ine cubsic synony) asi zvakare mune zvemagineti zvivakwa. Kuwedzera kune aya mafomu esimbi oxide (III), kune zvimwe zvinoshanda zvinoshamisa seEpsilon-, beta-, zeta- uye kunyange girazi. Chikamu chinonyanya kufarirwa ndiPepsion simbi oxide, ε-fe2o3. Uku kugadziridzwa kune yakanyanya kukosha inomanikidza simba (kugona kwezvinhu zvekuramba mari yekunze yemagineti). Simba rinosvika 20 koe pamhepo tembiricha, iyo yakafanana neye mazamu emagineti zvichienderana nezvinodhura zvisingawanzo-pasi zvinhu. Uyezve, zvinyorwa zvinobata Electromagnic radiation mu sub-terahertz frequency renje. Kune zvirongwa zvekushandisa iyo sub-teraherz mhando seyakashanda sangano muchizvarwa chechitanhatu (6G) tekinorozi isina waya isina waya, iyo iri kugadzirira kusuma inonakidza muhupenyu hwedu kubva kuma2030. Chinyorwa chinokonzeresa chakakodzera kugadzirwa kwekushandura zvikamu kana zvinotsausa matunhu pane aya mafuro. Semuenzaniso, nekushandisa manyorerwe okushandisa ε-fe2o3 nanopods zvichikwanisika kuita kuti pendi dzinotora mafungu epecksb. Iyo yeJ-FE2O3 iyo pachako inogona zvakare kushandiswa mune 6G yekugamuchira zvishandiso. Epsilon iron oxide inzira yakaoma kwazvo uye yakaoma yerudzi rwesimbi kuwana. Nhasi, inogadzirwa muhuwandu hushoma kwazvo, nemaitiro aya pachayo kutora kusvika pamwedzi. Izvi, zvechokwadi, anotonga chikumbiro chayo chakapararira. Vanyori vechidzidzo vakagadzira nzira yekukwirisa synthesis yeEpsion iron oxide Maitiro ari nyore kubereka, zvakachipa uye zvinogona kuitwa nyore nyore muindasitiri, uye zvigadzirwa zvinodiwa kuti synthesis - iron uye silicon - zviri pakati pezvakawanda zvinhu zvepasi. "Kunyangwe iyo EPSILON-Iron Oxide chikamu chakawanikwa mune yakachena fomu kwenguva yakareba, muna 2004, iyo haina kuwana application yekunyanyisa nekuda kwekunetseka kweiyo synthesis, semuenzaniso sepakati kune magineti - kurekodha. Takakwanisa kurerutsa tekinoroji zvakanyanya, "anodaro Evgeny gorbachev, mudzidzi wePHD muDhipatimendi reScience At Moscow State University uye wekutanga munyori webasa. Iyo kiyi yekubudirira kushandiswa kwezvinhu zvine humbowo-hwekuputsa hunhu hwokutsvagisa mune yavo yakakosha yemuviri zvivakwa. Pasina kudzidza zvakadzama, zvinyorwa izvi zvinogona kunge zvakakanganikwa zvisina kukodzera kwemakore mazhinji, sezvakaitika kanopfuura kamwechete munhoroondo yesainzi. Yaive iyo tandem yemasayendisiti emidziyo kuMoscow State University, uyo akashongedza nzvimbo, uye fizikisi kuMupt, aizvidzidza zvakadzama, izvo zvakaita kuti vabudirire kubudirira.
