LADP-3 Microwave Electron Spin Resonance Apparatus

Fa'amatalaga Puupuu:

Electron spin resonance ua ta'ua foi o le electron paramagnetic resonance, lea e faasino i le tulaga o le suiga o le resonance i le va o le maualuga o le malosi o le eletise eletise taimi maneta pe a aafia i le galu electromagnetic tutusa i le malae mageta.E mafai ona matauina lenei mea mata'utia i mea fa'amagnetic fa'atasi ai ma taimi fa'amaneta vili e le'i fa'aluaina (fa'aa'oa'oga o lo'o iai ni eletise e le'i fa'atasi).O le mea lea, o le electron spin resonance o se auala taua e iloa ai le uncoupled electrons i mataupu ma latou fegalegaleaiga ma atoms siomia, ina ia maua ai le faamatalaga e uiga i le microstructure o mea.O lenei metotia e maualuga le maaleale ma le fofo, ma e mafai ona faʻaaogaina e suʻesuʻe ai mea i auiliiliga e aunoa ma le faʻaleagaina o le faʻataʻitaʻiga faʻataʻitaʻiga ma leai se faʻalavelave i gaioiga faʻamaʻi.I le taimi nei, o loʻo faʻaaogaina lautele i suʻesuʻega o le fisiki, kemisi, biology ma vailaʻau.

Fa'ata'ita'iga

1. Su'esu'e ma fa'ailoa le fa'alavelave fa'afuase'i ole vili eletise.

2. Fua Lande'sg-vaega ole DPPH fa'ata'ita'iga.

3. A'oa'o pe fa'apefea ona fa'aoga masini microwave i le EPR system.

4. Malamalama i le galu tu e ala i le suia o le umi o le oga ma fuafua le umi ole galu.

5. Fua le fa'asoaina o fanua galu tu i totonu o le lua fa'asolo ma fuafua le umi ole galu.
