We obtain subordination and superordination preserving properties for the Saigo type generalized fractional differ-integral operator, defined for multivalent functions in the open unit disk. A differential sandwich-type theorem for these multivalent function, and some consequences are also presented.

A coalgebraic, equational approach to the specification of observational structures allowing for a choice in the result type of observations is presented. Coalgebraic operations whose result type is structured as a coproduct of basic types are considered, and notions of coterm, covariable and coequation, dual to the algebraic notions of term, variable and equation, are used to specify structure...

Half-sandwich iridium complexes bearing hydroxyindanimine ligands were synthesized and employed as catalysts for the ROMP and vinyl-type polymerization of norbornene in the presence of methylaluminoxane (MAO).

A novel probe-type FPI-based fiber optic hydrogen sensor with a graphene–Au–Pd sandwich structure film and FBG is proposed experimentally demonstrated in this study.

Hemin/G-quadruplex-based DNAzyme concatamers were utilized as electrocatalysts and biolabels to construct a sandwich-type electrochemical immunosensor for sensitive detection of IgG1 (as a model analyte).

The present work relates to the synthesis and spectral properties of erbium sandwich type metal complexes containing tetraanthraquinoporphyrazine as well phthalocyanine fragments. By reacting tetraanthrachinoporphirazine (lutetium) acetate with excess phthalonitrile, 4-chloro, 4-bromophthalonitrile unsubstituted sandwich-type an unsymmetrical structure were obtained. compounds extracted from re...
