On unified gould-hopper based apostol-type polynomials
(International Scientific Research Publications, 2021)
In this paper, we consider unified Gould-Hopper based Apostol-type polynomials and investigate some of their formulas including several implicit summation formulae and some symmetric identities by the series manipulation ...
Some Identities of the Degenerate Multi-Poly-Bernoulli Polynomials of Complex Variable
(Hindawi Limited, 2021)
In this paper, we introduce degenerate multi-poly-Bernoulli polynomials and derive some identities of these polynomials. We give some relationship between degenerate multi-poly-Bernoulli polynomials degenerate Whitney ...
Non-fullerene organic photovoltaics based on thienopyrroledione comprising random copolymers; effect of alkyl chains
(Elsevier, 2021)
Two new random donor-acceptor (D-A) copolymers, signed as P1 and P2, were designed and synthesized. Electrochemical and spectroelectrochemical measurements were performed to investigate absorption, energy levels, electronic ...
Diastereomeric Separation of a Novel Chalcone Derivative by Chiral HPLC
(Adıyaman Üniversitesi Fen Bilimleri Dergisi, 2021)
In this study, a facile and versatile procedure for the synthesis of a chalcone derivate that
a functionalized (E,Z)-2-(4-aminobenzylidene)acenaphthylen-1(2H)-one, 4 was synthesized and
also characterized by using FT-IR, ...
Study on the Field-Dependent Activation Energy, U(H,T), Upper Critical Field, Hc2(0), and Irreversibility Field, µ0Hirr, Properties of Superconducting Single-Crystal Ag-Added Fe(Se, Te) Alloys
(Springer, 2022)
Superconducting FeTe0.5Se0.5 + Ag single-crystal samples with 0, 1, 2, 3, 4, and 5% Ag concentrations were prepared successfully by the self-flux synthesis method. Structural, electrical transport, and magnetic characterizations, ...
Structural and optical characteristics of antimony selenosulfide thin films prepared by two-step method
(Korean Physical Society, 2022)
Antimony triselenide (Sb2Se3) is one of the most promising absorber material choices among the inorganic semiconductors that has attracted much attention today. However, highest recorded efficiencies for Sb2Se3 solar cells ...
Classification of Surfaces of Coordinate Finite Type in the Lorentz–Minkowski 3-Space
(MDPI, 2022)
In this paper, we define surfaces of revolution without parabolic points in three-dimensional Lorentz–Minkowski space. Then, we classify this class of surfaces under the condition ∆I I I x = Ax, where ∆I I I is the Laplace ...
Diverse Properties and Approximate Roots for a Novel Kinds of the (p, q)-Cosine and (p, q)-Sine Geometric Polynomials
(MDPI, 2022)
Utilizing (p, q)-numbers and (p, q)-concepts, in 2016, Duran et al. considered (p, q)-Genocchi numbers and polynomials, (p, q)-Bernoulli numbers and polynomials and (p, q)-Euler polynomials and numbers and provided ...
Convergence Analysis and Approximate Optimal Temporal Step Sizes for Some Finite Difference Methods Discretising Fisher's Equation
(Frontiers Media S.A., 2022)
In this study, we obtain a numerical solution for Fisher's equation using a numerical experiment with three different cases. The three cases correspond to different coefficients for the reaction term. We use three numerical ...
Syntheses of novel fluorinated dibenzo[a,c]phenazine comprising polymers for electrochromic device applications
(Royal Society of Chemistry, 2022)
In this study, two novel fluorinated dibenzo[a,c]phenazine derivatives, 2,7-bis(5-bromo-4-hexylthiophen-2-yl)-11-fluorodibenzo[a,c]phenazine (TFBPz) and 2,7-bis(2,3-dihydrothieno[3,4-b][1,4]dioxin-5-yl)-11-fluorodibenzo[ ...
