《Systematics of positron lifetime spectroscopy measurements in ferroelectrics》 was written by Peneva, S.; Troev, T.; Kolev, B.. Quality Control of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate And the article was included in Journal of Physics: Conference Series in 2020. The article conveys some information:
In the paper is demonstrated the use of positron lifetime spectroscopy (PLS) in a comparative study of the results in ferroelecs. The first part is devoted to the application of PLS as a probe for measurements of ferroelecs. In Triglycine Sulfate (TGS) (NH3CH2COOH)3H2SO4, Rochelle Salt (RS) NaKC4H4O64H2O and Potassium Dihydrogen Phosphate (KDP) KH2PO4; at different temperatures and gamma irradiation doses is established the existence of three positron lifetime components. This exptl. results show that the second long lifetime component as a function of temperature in order-disorder ferroelecs. TGS, RS and KDP is due to the positron trapping in neg. charge defects of ferroelec. The positron spectroscopy method is effective for measurements of extremely small defects and voids, which is important for the next exploitation period of the ferroelecs. PLS measurements of ferroelecs. show that about the third lifetime component is due to the local formation of orhto-positronium state on the boundary between the domains. In the second part the PLS anal. has been applied for examination the electronic and defect structure in selected ferroelecs. materials. In gamma irradiated TGS positrons are trapped in the defect states of the oxygen ions of the two radicals CH2COO- and NH3CHCOO-. In RS positrons are trapped also in the defect states of the oxygen ions and OH groups.Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5Quality Control of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate) was used in this study.
Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate(cas: 6381-59-5) is a ferroelectric crystal with a high piezoelectric effect and electromechanical coupling coefficient. Quality Control of Potassium sodium (2R,3R)-2,3-dihydroxysuccinate tetrahydrate It may be used as a constituent to prepare DNS (3,5- dinitrosalicylic acid) reagent and Fehling′s solution B, which are used in the determination of reducing sugar.
