Solid-state compatibility of Ca:LaNbO4 with perovskite cathodes: Evidences from X-ray microspectroscopy

2022

The solid-state compatibility between calcium-doped lanthanum niobate and three perovskite cathode materials was investigated using two X-ray microbeam techniques, micro X-ray fluorescence and micro X-ray absorption spectroscopy. The cathode powders (lanthanum strontium ferrite, either cobalt or copper-doped, and lanthanum strontium cobaltite) in contact with the dense electrolyte pellet were annealed at 1150 degrees C for 12-144 h to simulate the effect of thermal stresses due to fabrication and long-term operation. As a result, several interdiffusion phenomena were then observed on the bilayer cross-sections: in particular, the chemical state and coordination environment of calcium, iron,…

Współczesna wojna - model klasyfikacyjny surowców krytycznych

2016

The paper adresses the problem of the list of critical raw materials for the European Union. The theoretical model of classification of the critical raw materials was presented. The presented model is based on two variables: index of the compatibility (substitutability index) and recycling index.

Extended valence theory perspective on consumers' e-waste recycling intentions in Japan

2021

The gravity of the electronic waste (e-waste) crisis can be attributed to consumers' low participation in ensuring the proper disposal of such materials. Motivating consumers to recycle e-waste requires a deeper understanding of the dimensions that underlie behavioral intentions. Accordingly, the present study uses the novel framework of Valence Theory (VT) to examine how consumers evaluate their decision to recycle e-waste. The authors propose an extended VT model incorporating consumer values (value compatibility, openness to change, and environmental concerns), which is validated using cross-sectional survey data from 774 Japanese consumers. We also examine the role of different moderato…

Design and Assessment of Optimized EMI Filters for Avionic Applications

2018

This paper presents a procedure to design EMI filters to reduce the electromagnetic disturbances generated by electrical apparatus used in avionic environment. The method proposed can be useful to save weight and size of the attenuation systems, and keep their effectiveness in agreement with the standard requirements. A design of a set of different filters with different topological characteristics is presented for a case study about an electrical actuator used for an aircraft onboard application. Performances and reliabilities of the attenuation systems are assessed by suitable full compliance experimental tests.

Biomimetic strategy towards gelatin coatings on PET. Effect of protocol on coating stability and cell-interactive properties

2019

Gelatin-modified poly(ethylene terephthalate) (PET) surfaces have been previously realized via an intermediate dopamine coating procedure that resulted in surfaces with superior haemocompatibility compared to unfunctionalized PET. The present study addresses the biocompatibility assessment of these coated PET surfaces. In this context, the stability of the gelatin coating upon exposure to physiological conditions and its cell-interactive properties were investigated. The proposed gelatin–dopamine-PET surfaces showed an increased protein coating stability up to 24 days and promoted the attachment and spreading of both endothelial cells (ECs) and smooth muscle cells (SMCs). In parallel, physi…

Innovative technologies for temporary architecture

2009

Problem risen from temporariness and flexibility concepts of built concern, always constituted, all over technological advanced countries and throughout the whole history of scientific research, some of the most interesting aspects of technologies, industry and industrialization processes. Several project proposals about really light structures easily gatherable, transportable, that can be dismantled and reconverted, are proves of that such as their use in order to obtain flexible and functional living solutions. They are systems adaptable to different needs and fit to offer a concrete solution for the necessities related to the new ways of living. In fact temporary buildings that were thou…
