Bottom‐Up Fabrication of Semiconductive Metal-Organic Framework Ultrathin Films
2018
Though generally considered insulating, recent progress on the discovery of conductive porous metal-organic frameworks (MOFs) offers new opportunities for their integration as electroactive components in electronic devices. Compared to classical semiconductors, these metal-organic hybrids combine the crystallinity of inorganic materials with easier chemical functionalization and processability. Still, future development depends on the ability to produce high-quality films with fine control over their orientation, crystallinity, homogeneity, and thickness. Here self-assembled monolayer substrate modification and bottom-up techniques are used to produce preferentially oriented, ultrathin, con…
Chemical Design and Magnetic Ordering in Thin Layers of 2D Metal–Organic Frameworks (MOFs)
2021
Through rational chemical design, and thanks to the hybrid nature of metal−organic frameworks (MOFs), it is possible to prepare molecule-based 2D magnetic materials stable at ambient conditions. Here, we illustrate the versatility of this approach by changing both the metallic nodes and the ligands in a family of layered MOFs that allows the tuning of their magnetic properties. Specifically, the reaction of benzimidazole-type ligands with different metal centers (MII = Fe, Co, Mn, Zn) in a solventfree synthesis produces a family of crystalline materials, denoted as MUV-1(M), which order antiferromagnetically with critical temperatures that depend on M. Furthermore, the incorporation o…
Surfactant-assisted synthesis of titanium nanoMOFs for thin film fabrication
2021
We use dodecanoic acid as a modulator to yield titanium MOF nanoparticles with good control of size and colloid stability and minimum impact to the properties of the framework to enable direct fabrication of crystalline, porous thin films. ispartof: CHEMICAL COMMUNICATIONS vol:57 issue:72 pages:9040-9043 ispartof: location:England status: published
Conceptual framework and measurement: A survey on the international debate
2015
In response to the ‘2011 Agenda Consultation’, the IASB launched in July 2013 a call for a new Discussion Paper on the ‘Conceptual Framework for Financial Reporting’. This article aims to offer a contribution to the debate on the effectiveness of the theme of ‘Measurement’, by investigating the use of the current evaluation models in the literature and practice of Financial Reporting. The article proposes at first a historical survey both of the international debate on Fair Value Accounting vs. Historical Cost Accounting and of the Italian theories on the valuation. Later the paper proposes some considerations about the key questions related to Measurement and the possible policy implicatio…
Good Old-Fashioned Artificial Consciousness and the Intermediate Level Fallacy
2018
Recently, there has been considerable interest and effort to the possibility to design and implement conscious robots, i.e., the chance that a robot may have subjective experiences. However, typical approaches as the global workspace, information integration, enaction, cognitive mechanisms, embodiment, i.e., the Good Old-Fashioned Artificial Consciousness, henceforth, GOFAC, share the same conceptual framework. In this paper, we discuss GOFAC's basic tenets and their implication for AI and Robotics. In particular, we point out the intermediate level fallacy as the central issue affecting GOFAC. Finally, we outline a possible alternative conceptual framework towards robot consciousness.
A standard conceptual framework for the study of subjective time.
2019
Research on the mental representation of time ('subjective time') has provided broad insights into the nature of time perception and temporal processing. As the field comprises different scientific disciplines, such as psychology, philosophy, and neuroscience, studies differ with regard to the basic terms and concepts used. For this reason, research on subjective time lacks a coherent conceptual system. We argue that research in the field of subjective time should aim at establishing such a system, i.e., a more standardized terminology, in order to strengthen its theoretical basis and to support an efficient communication of results. Based on key empirical findings and concepts that are com…
The European Union at the Copenhagen climate negotiations: A case of contested EU actorness and effectiveness
2013
This article analyses the extent of European Union (EU) actorness and effectiveness at the 15th United Nations Framework Convention on Climate Change (UNFCCC) Conference of the Parties (COP) meeting in Copenhagen in December 2009. Although the EU has been characterised as a leader in international climate policy-making for some time, the COP 15 meeting in Copenhagen has overall brought about disappointing outcomes for the Union. This casts doubts on EU actorness and effectiveness in this field. We take the article by Jupille and Caporaso as a conceptual point of departure and then specify a more parsimonious actorness framework that consists of coherence and autonomy. Effectiveness is conc…
Stop the bleeding or weather the storm? crisis solution marketing and the ideological use of metaphor in online financial reporting of the stock mark…
2014
Introducing the concept of Crisis Solution Marketing (CSM), this research explores how metaphor pre-packages information, proposing “solutions” to “problems” they discursively construct in the media. These conceptual frameworks are capable of influencing how readers perceive and interpret news events, ultimately influencing their behavior as consumers and the financial decisions they make. This article explores the relationship between editorial positioning and ideology in financial news and the types or ontologies of metaphors used to describe the nature of the stock market via reporting on the stock market crash of 2008 in online news media. Results indicate a statistically significant p…
Analysing the Financial Soundness of the Commercial Banks in Romania: An Approach based on the Camels Framework
2013
Abstract The Romanian banking system has undergone through tremendous changes in the last decade, its financial soundness and performance being paramount in the achievement of a stable and sustainable economic growth. Thus, the aim of our research is to comparatively analyse the financial soundness of the commercial banks that operate in Romania. In order to achieve this we have used one of the most popular methods for the analysis of the financial soundness of banks, namely the CAMELS framework. The obtained results highlight the strengths and the vulnerabilities of the analysed banks, underlining the need to strengthen the concerns of the decision makers from banks to improve and increase…
Fine-tuning of the confined space in microporous metal–organic frameworks for efficient mercury removal
2017
Offsetting the impact of human activities on the biogeochemical cycle of mercury has become necessary for a sustainable planet. Herein, we report the development of a water-stable and eco-friendly metal–organic framework, which has the formula {Cu4II[(S,S)-methox]2}·5H2O (1), where methox is bis[(S)-methionine]oxalyl diamide. Its features include narrow functional channels decorated with thioalkyl chains, which are able to capture HgCl2 from aqueous media in an efficient, selective, and rapid manner. The conscious design effort in terms of size, shape, and reactivity of the channels results in extremely efficient immobilization of HgCl2 guest species in a very stable conformation, similar t…
