Abstract A new ratiometric fluorescent sensor ( 1 ) for Cu 2+ based on 4,4‐difluoro‐4‐bora‐3a,4a‐diaza‐ s ‐indacene (BODIPY) with di(2‐picolyl)amine (DPA) as ion recognition subunit has been synthesized and investigated in this work. The binding abilities of towards different metal ions such alkali alkaline earth (Na + , K Mg Ca other Ba Zn Cd Fe 3+ Pb Ni Co Hg Ag have examined by UV‐vis fluorescence spectroscopies. displays high selectivity among all test a ∼10‐fold enhancement I 582 / 558...
We consider the scattering of time‐harmonic acoustic plane waves by a crack buried in piecewise homogeneous medium. The integral representation for solution is obtained form potentials using Green's formula. density satisfies uniquely solvable Fredholm equation. Then we obtain existence and uniqueness solution.

Abstract In this paper we consider the inverse scattering problem of determining shape a two-layered cavity with conductive boundary condition from sources and measurements placed on curve inside cavity. First, show well-posedness direct by using integral equation method. Then, prove that factorization method can be applied to reconstruct interface near-field data. Some numerical experiments are also presented demonstrate feasibility effectiveness
We consider the scattering problem of time-harmonic electromagnetic waves from an infinite cylinder having open arc and a bounded domain in R2 as cross section. To this end, we solve mixed for Helmholtz equation where object is combination Γ obstacle D. The well-posedness solution to direct established by using boundary integral method Fredholm theory.
We consider a kind of scattering problem which models the an electromagnetic time-harmonic plane wave by infinite cylinder having open arc and penetrable obstacle in R2 as cross section, is buried piecewise homogeneous medium. To this end, we solve for Helmholtz equation where object crack Γ inside bounded domain D, have Dirichlet-Impedance type boundary condition on transmission D. Applying potential theory, can be reformulated integral system. establish existence uniqueness weak solution...
Abstract In this paper, we consider the inverse scattering problem of identifying a two-layered cavity by internal acoustic measurements under condition that interior interface has mixed transmission boundary condition. We focus on mathematical analysis recovering shape using linear sampling method, including reconstructing surface conductivity same measurements.
