A characterization of a certain class of arithmetical multiplicative functions

open access: yesLe Matematiche, 1995
The object of this paper is the set of the "arithmetical multiplicative functions", i.e. the functions ℕ --> ℂ for which f(mn)=f(n)f(m), under the condition that m and n have no common factors.

Applications of Mittag–Leffler Functions on a Subclass of Meromorphic Functions Influenced by the Definition of a Non-Newtonian Derivative

open access: yesFractal and Fractional
In this paper, we defined a new family of meromorphic functions whose analytic characterization was motivated by the definition of the multiplicative derivative.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Microstructural Evolution Dominates the Changes in the Thermal Conductivity of Conjugated Polymers Upon Doping

open access: yesAdvanced Functional Materials, EarlyView.
The relationship between the doping induced microstructure and thermal conductivity changes is elucidated for conjugated polymers. Eight conjugated polymers with different doping systems are studied, showing varied thermal conductivity responses based on structural order.

Sturm-Liouville problem in multiplicative fractional calculus

open access: yesAIMS Mathematics
Multiplicative calculus, or geometric calculus, is an alternative to classical calculus that relies on division and multiplication as opposed to addition and subtraction, which are the basic operations of classical calculus.
