Nanoscale chemistry and atomic-scale microstructure of a bulk Ni3Sn material built using selective laser melting of elemental powder blends

2021

Abstract Cubic specimens of the intermetallic Ni3Sn compound were built using selective laser melting of elemental powder blends. A specimen built at a laser power of 200 W and a scanning speed of 0.5 m/s was determined to have a homogeneous distribution of Ni and Sn on a mesoscopic scale in spite of a 2 at.% Sn deficiency. Characterization of the microstructure using the HAADF-STEM technique reveals a dispersion of ultrafine Ni particles, nanoscale chemical inhomogeneity and the formation of antiphase nanodomains in the matrix of equiaxed Ni3Sn grains. While a mesoscopic homogeneity of the specimen demonstrates a prospect of additive manufacturing of a bulk intermetallic material using sel…

The Role of Equity Crowdfunding Campaigns in Shaping Firm Innovativeness: Evidence from Italy

2023

PurposeThis paper aims to contribute to the scientific debate concerning the impact of equity crowdfunding on the performance of crowdfunded firms after campaigning. To this aim, the purpose of this paper is to investigate the relationship between the characteristics of the campaign and the subsequent firm innovativeness.Design/methodology/approachThis study adopts a quantitative research approach to evaluate if the entrepreneurial choices affecting the characteristics of the equity crowdfunding campaigns have an impact on the post-campaign firm innovativeness.FindingsThe results of the models show that the campaign characteristics have a direct impact on the firm innovativeness, both in te…

Investment behavior analysis in equity crowdfunding : A consumer value approach

2018

Equity crowdfunding is a recent investment mode, opening acces to venture capital to unsophisticated investors. ECF allows platform-based online investment within a virtual community.This research aims to improve understanding of indivual investors financial products consumption, in the ECF context, the so-called crowdinvestors.Building on consumption value theory, this research helps defining ECF-investment value sources for crowdinvestors. It focuses especially on the ‘participation in community’ dimension of ECF as a determinant of various investment behaviors.A litterature review in entrepreneurial finance is presented to define profiles, motivations, investment behaviors and quality si…

Hunting for valuables from landfills and assessing their market opportunities A case study with Kudjape landfill in Estonia

2017

Landfill mining is an alternative technology that merges the ideas of material recycling and sustainable waste management. This paper reports a case study to estimate the value of landfilled materials and their respective market opportunities, based on a full-scale landfill mining project in Estonia. During the project, a dump site (Kudjape, Estonia) was excavated with the main objectives of extracting soil-like final cover material with the function of methane degradation. In total, about 57,777 m3 of waste was processed, particularly the uppermost 10-year layer of waste. Manual sorting was performed in four test pits to determine the detailed composition of wastes. 11,610 kg of waste was…

Mindfulness, perceived stress, and subjective well-being: a correlational study in primary care health professionals

2015

Background Primary health care professionals (PHPs) usually report high levels of distress and burnout symptoms related to job strain. Mindfulness, defined as non-judgmental-present-moment awareness, seems to be a moderator in the causal association between life stressors and well-being. This study aimed to verify correlations among self-reported mindfulness, perceived stress (PS), and subjective well-being (SW) in Brazilian PHPs. Methods We performed a correlational cross-sectional study in a purposive sample of Brazilian PHPs (physicians, nurses, nursing assistants, and community health workers), working in community-oriented primary care programs (known locally as “Family Health Programs…

Comparative analysis of the European Union crowdfunding service providers regulation and regulatory barriers for crowdfunding in the Baltic States

2021

The issue of conflicting national frameworks on crowdfunding and dispersed structures of investors and products has drawn significant attention in the European Union. Some Member States introduced national rules to regulate their crowdfunding platforms, while others left some aspects of the activity unregulated. This variation of national licensing, diverging definitions of business models and application of existing EU legislation are considered to contribute to crowdfunding market fragmentation. Some surveys demonstrate that crowdfunding regulatory heterogeneity in the Member States negatively affects the market. In the paper, this heterogeneity is revised on the example of Latvia, Lithua…
