Amapayipi e-Microwave kanye ne-Vacuum:

Isetshenziswa kuma-magnetron, ama-klystrons, nama-traveling-wave tubes (ama-TWT) ezinhlelweni ze-radar, ukuxhumana ngesathelayithi, kanye nobuchwepheshe bokuzivikela.

2. Isayensi Yokukhiqiza Ethuthukisiwe Nezinto Ezisetshenziswayo

Ukushisela Nokushisa Nge-Electron Beam:

Ihlinzeka ngemithombo yokushisa egxile kakhulu yokushisela ngokunemba, ukukhiqizwa kwezithasiselo, kanye nokwelashwa kwendawo ezimbonini zezindiza nezimoto.

Ukugqoka kanye namafilimu amancane:

Kusetshenziswa njengezembozo ezivikelayo kuma-blade e-turbine, kuma-nozzle e-rocket, kanye nezingxenye ze-reactor yenuzi ukuze zimelane nokushisa okukhulu kanye nokushiswa kwe-oxidation.

I-Single-Crystal LaB₆:

Isebenza njengento esezingeni eliphezulu ye-cathode kuma-particle accelerator, ama-synchrotron, kanye nezinhlelo zokufakelwa kwama-ion.

3. Izinsimbi Zokuhlaziya

Amazinga e-X-Ray Diffraction (XRD):

Isebenza njengezinto zokubhekisela zosayizi/ubunzima eziqinisekisiwe ukuze kulinganiswe ukunwetshwa kwezinsimbi ekuhlaziyweni kwe-XRD, kuqinisekiswe ukunemba ezifundweni ze-crystallographic.

Amapayipi e-X-Ray:

Kuthuthukisa ukukhanya nokusebenza kahle emithonjeni ye-X-ray yezokwelapha neyezimboni.

4. Ubuchwepheshe Obusha kanye Ne-Niche

I-Quantum Computing kanye nocwaningo:

Kuphenywe ukusetshenziswa kuma-quantum emitters kanye namadivayisi e-spintronic ngenxa yokusabalala kwayo okuphansi kwama-electron kanye nokuhamba okuphezulu kokuthwala.

Amaphaneli Okubonisa I-Plasma (ama-PDP):

Kuthuthukisa ukusebenza kahle kanye nokuphila kwesikhathi kuzibonisi ezicacile.

Ukuhlola Isikhala:

Isetshenziswa kuma-ion thrusters kanye nezinzwa zezindiza zasemkhathini emisebenzini yasemkhathini ojulile.

5. Izicelo Zezimboni Nezemvelo

Izinzwa Zokushisa Okuphezulu:

Isebenza kuma-thermocouple kanye nama-thermal probe ezinqubo ze-metallurgical kanye nokuqapha insimbi encibilikisiwe.

Izinto Zokuphatha Okukhulu:

Uhlole izinto ezihlanganisiwe ze-superconducting zokugcina amandla kanye nezinhlelo ze-magnetic levitation.

Izinzuzo Eziyinhloko ze-LaB₆

Ukuzinza Okuphezulu Kokushisa: Kugcina ukusebenza kahle ezindaweni ezibucayi (kufika ku-1,800°C ku-vacuum).

Ukungasebenzi Kwamakhemikhali: Kumelana nokugqwala okuvela kuma-asidi, ama-alkali, kanye namagesi asabelayo.

Ubude Besikhathi: Idlula ama-cathode e-tungsten ngokuphindwe ka-10-20 esikhathini sokusebenza.

Izinzuzo Eziqondene Nemboni

Izindiza Nokuvikela: Izinhlelo ze-radar ezithembekile, ukuxhumana ngesathelayithi, kanye nezingubo zokuvikela ukushisa.

Ama-semiconductor: Inika amandla i-lithography yesizukulwane esilandelayo yokwenziwa kwama-chip angaphansi kwe-5nm.

Ucwaningo Nokunakekelwa Kwezempilo: Ukuthwebula izithombe ezinesinqumo esiphezulu kuma-TEM kanye nokuxilongwa kwe-X-ray okuthuthukisiwe.

I-Lanthanum Hexaboride iyitshe lesisekelo lezimboni zesimanje zobuchwepheshe obuphezulu, eqhuba ukusungula izinto ezintsha kwezobuchwepheshe be-nanotechnology, amandla, kanye nesayensi ye-quantum. Amandla ayo okukhipha ama-electron angenakuqhathaniswa kanye nokuqina kwayo kuqinisa indima yayo njengento ebalulekile kokubili ubuchwepheshe bamanje nobesizukulwane esilandelayo.

Qaphela: Ama-nanoparticle e-LaB₆ asetshenziswa kakhulu ekubonisweni kwe-field-emission (ama-FED) kanye nama-nanoelectronics, okugqamisa ukuzivumelanisa kwayo nezidingo zobuchwepheshe ezishintshashintshayo.
