The purpose of this paper is to contribute an analytical and numerical study of a new type of nanoshell particles operating in the visible regime.

The structure consists of a core/shell particle, arranged in a planar array configuration, with a polymethyl methacrylate (PMMA)-graphene core and gold thin shell.

By exploiting the proposed analytical model the design of a metamaterial-based sensor, operating in the optical frequency range, for the detection of tissue diseases is shown.

Full-wave simulations confirm the capability of the proposed sensor to identify different compounds by refractive index measurement.

In this contribution, the aim is to present a nanoparticle device, operating in the visible regime based on the localized surface plasmon resonance (LSPR) phenomenon.

The nanoparticle electromagnetic properties are evaluated by a new analytical model and compared to the results obtained by numerical analysis.

A near-field enhancement is obtained by arranging the nanoparticles in a linear array. Analytical formulas, describing such enhancement, are presented.

The results demonstrate the possibility to use the proposed device for medical diagnostics and optoelectronics applications.

The aim of this paper is to examine marketing practices within the bicycle industry.

The paper utilizes both primary and secondary sources to provide a retrospective analysis of marketing strategy at the largest Italian bicycle company.

The paper explains how marketing works at the Bianchi company and provides a detailed analysis of how it built its brand identity over time.

Very few primary sources were available. There was neither a company archive nor other archives. For the most part, the paper is based on secondary sources.

The paper tries to fill the gap in current marketing literature that usually neglects the bicycle as a relevant topic, despite bicycle companies being a predecessor to the automobile industry. Moreover, the paper demonstrates that bicycle companies developed a rather sophisticated approach to marketing that is still in use.
