Manganese/yttrium codoped strontium nanohexaferrites: Evaluation of magnetic susceptibility and mossbauer spectra
(MDPI AG, 2019)
Abstract: Manganese (Mn)- and yttrium (Y)-substituted Sr-nanohexaferrites (MYSNHFs) of composition Sr1_xMnxFe12_xYxO19 (with 0.0 ≤ x ≤ 0.5) were prepared by citrate sol-gel autocombustion method. As-prepared MYSNHFs were ...
Elastic, mechanical and phonon behavior of wurtzite cadmium sulfide under pressure
(MDPI AG, 2017)
Cadmium sulfide is one of the cutting-edge materials of current optoelectronic technology. Although many theoretical works are presented the for pressure-dependent elastic and related properties of the zinc blende crystal ...
Theoretical analysis of elastic, mechanical and phonon properties of wurtzite zinc sulfide under pressure
(MDPI AG, 2017)
We report for the first time the application of a mixed-type interatomic potential to determine the high-pressure elastic, mechanical, and phonon properties of wurtzite zinc sulfide (WZ-ZnS) with geometry optimization ...
Nucleophilic and electrophilic cyclization of N-alkyne-substituted pyrrole derivatives: Synthesis of pyrrolopyrazinone, pyrrolotriazinone, and pyrrolooxazinone moieties
(Beilstein-Institut Zur Forderung der Chemischen Wissenschaften, 2017)
Intramolecular nucleophilic and electrophilic cyclization of N-alkyne-substituted pyrrole esters is described. Efficient routes towards the synthesis of pyrrolopyrazinone, pyrrolotriazinone and pyrrolooxazinone have been ...
A novel core-shell-based chromatographic method supported by ratio derivative spectrophotometry for the simultaneous determination of perindopril, indapamide, and amlodipine ternary mixtures
(TUBİTAK, 2018)
In this work, ratio spectra of the frst derivative spectrophotometric and liquid chromatographic methods have been described for the frst time for the simultaneous determination of perindopril (PER), indapamide (IND), and ...

Some new Zn(II) and Cu(II) complexes [Cu(L1)(OAc)2]·H2O, [Cu(L1)(NO3)H2O]·NO3·3.5H2O, [Zn(L1)(NO3)2]·4.5H2O, [Zn(L1)(OAc)2(H2O)2]·3H2O, [Cu2(L2)(OAc)4]·2H2O·2DMF, [Cu(L2)2]·2NO3·1.5DMF·H2O, [Zn(L2)2(NO3)2]·DMF and ...
Sturm-Liouville problem with moving discontinuity points
(Springer International Publishing, 2015)
In this paper, we present a new discontinuous Sturm-Liouville problem with symmetrically located discontinuities which are defined depending on a parameter in the neighborhood of an interior point in the interval. Also the ...

The mayfly fauna of Turkey was reviewed including all hitherto known distribution records together with references and a few new records. Additionally, comments on taxonomy, identification and nomenclature are provided. ...
Determination of biogenic amines at low μg L–1levels as acetylacetone derivatives by RP-HPLC with UV-visible detection in expired apple juice samples
(Slovensko Kemijsko Drustvo, 2018)
An accurate and sensitive method for trace quantification of three biogenic amines in expired apple juice samples based on reversed-phase liquid chromatography (RP-HPLC) with UV-visible detection is described. Biogenic ...
