We apply first-principles method to investigate the effect of the diameter on the stability and electronic properties of zigzag carbon nanotubes doped with iron, nickel and manganese impurity atoms. In this contribution we follow the evolution of the electronic and structural properties as a...

We have studied, through ab initio calculations, the stability of 60° and 120° boron nitride nanocones containing mono and multiple boron, nitrogen, and carbon vacancies. The stability of the vacancies as well as the structures reconstruction mechanism have been investigated. Our results...

The stability and electronic structure of BC2N compounds are studied using first-principle calculations. The investigated structures have the topology of graphite layers with either carbon, nitrogen or boron atoms at each site. The calculations show that stabler structures are obtained by...

This paper aims to study the influence of eco-innovation practices on eco-efficiency of business, which embraces environmental and economic performance. Four hypotheses are drawn up based on the existing literature in green supply chain and considering the business innovation. A survey...

Consumer behaviour research is the scientific study of the processes consumers use to select, secure, use and dispose of products and services that satisfy their needs. Firms can satisfy those needs only to the extent that they understand their customers. The main objective of this paper is to...

An important factor that guarantees a persistent competitive advantage is the sustainability of the firm’s capabilities or their core competences. These capabilities should form the basic support of firm’s strategy. Several authors point out the importance of the information systems (IS) for...

This research provides a useful framework for identifying a small firms’ propensity to engage in entrepreneurial orientation. We examine the impact of the Entrepreneurial Orientation (EO) as a main resource and capability on small firm' growth. The growth seems to come out as an important...
