Design of Magnetic Coordination Polymers Built from Polyoxalamide Ligands: A Thirty Year Story
2018
International audience; The aim of this review is to pay tribute to the legacy of O. Kahn. Kahn's credo was to synthesize magnetic compounds with predictable structure and magnetic properties. This is illustrated herein with results obtained by Kahn's group during his Orsay period thirty years ago, but also on the basis of our recent results on the synthesis of coordination polymers with oxamate ligands. The first part of this review is devoted to a short description of the necessary knowledge in physics and theoretical chemistry that Kahn and his group have used to select oxamate ligands, the complex‐as‐ligand strategy and the synthesis of heterobimetallic systems. Then, we describe the st…
Towards a Reference Architecture for Model-Driven Business Apps
2016
Model-driven development techniques have been proposed for cross-platform app development. Typically, an individual domain-specific language (DSL) is used. The MD² framework consists of a DSL for business apps and generators, which transform a domain model to native platform code. Prior research on it focused on language and general generator design, this paper accentuates the code generation stage. A reference architecture for the generated apps is proposed to accelerate the development of new generators for which architectural decisions had been made on ad-hoc basis up to now. Moreover, generators are going to expose similar structures that facilitate maintenance. Our proposal takes MD²'s…
Autonomous on-board data processing and instrument calibration software for the SO/PHI
2018
The extension of on-board data processing capabilities is an attractive option to reduce telemetry for scientific instruments on deep space missions. The challenges that this presents, however, require a comprehensive software system, which operates on the limited resources a data processing unit in space allows. We implemented such a system for the Polarimetric and Helioseismic Imager (PHI) on-board the Solar Orbiter (SO) spacecraft. It ensures autonomous operation to handle long command-response times, easy changing of the processes after new lessons have been learned and meticulous book-keeping of all operations to ensure scientific accuracy. This contribution presents the requirements a…
What motivates the adoption of green restaurant products and services? A systematic review and future research agenda
2021
Issues regarding green restaurants have received significant scholarly and practitioner attention in the last decade, particularly concerning why consumers adopt green restaurants. Although several reviews exist on green hospitality, a comprehensive review of the literature on consumers' green restaurant adoption is currently lacking. The following systematic literature review examines 50 research studies published on the consumer adoption of green restaurant services to address this gap accordingly. Through a detailed content analysis, the research profile and thematic analysis are presented. The review further identifies four key thematic foci: (a) consumer behavior variables studied, (b)…
Telestratora modulis profesionālajam sportam
2016
“Telestrātora modulis profesionālajam sportam” izstrādāts “SIA Playgineering Systems” uzņēmuma vajadzībām, tas lietotnes gala versijā ļaus lietotājam izveidot un atskaņot specifiska veida prezentācijas profesionālajam sportam . Lai izveidotu video “prezentāciju” lietotājam būs iespējams atvērt populārāko formātu video failu, un pauzes laikā ar piedāvātajiem rīkiem veidot informatīvu zīmējumu, kā arī pēc prezentācijas izveides saglabāt projektu, lai to varētu atskaņot un prezentēt vēlāk. Lietotne tika veidota programmēšanas valodā Python, projekti tika saglabāti ar JSON datu struktūras palīdzību, video kontrolēšana un atskaņošana tika realizēta ar Gstreamer palīdzību, kā arī dizains veidots …
Trimesic acid on Cu in ethanol: Potential-dependent transition from 2-D adsorbate to 3-D metal-organic framework
2017
We report the potential-dependent interactions of trimesic acid with Cu surfaces in EtOH. CV experiments and electrochemical surface-enhanced Raman spectroscopy show the presence of an adsorbed trimesic acid layer on Cu at potentials lower than 0 V vs Cu. The BTC coverage increases as the potential increases, reaching a maximum at 0 V. Based on molecular dynamics simulations, we report adsorption geometries and possible structures of the organic adlayer. We find that, depending on the crystal facet, trimesic acid adsorbs either flat or with one or two of the carboxyl groups facing the metal surface. At higher coverages, a multi-layer forms that is composed mostly of flat-lying trimesic acid…
A platform for the development and the validation of HW IP components starting from reference software specifications
2008
Abstract Signal processing algorithms become more and more efficient as a result of the developments of new standards. It is particularly true in the field video compression. However, at each improvement in efficiency and functionality, the complexity of the algorithms is also increasing. Textual specifications, that in the past were the original form of specifications, have been substituted by reference software which became the starting point of any design flow leading to implementation. Therefore, designing an embedded application has become equivalent to port a generic software on a, possibly heterogeneous, embedded platform. Such operation is getting more and more difficult because of …
Tuning the Photocatalytic Activity of Ti-Based Metal-Organic Frameworks through Modulator Defect-Engineered Functionalization.
2022
Defect engineering is a valuable tool to tune the photocatalytic activity of metal–organic frameworks (MOFs). Inducing defects through the attachment of functionalized modulators can introduce cooperative units that can tune the bandgap of the material and enhance their chemical, thermal, and photostabilities among other properties. However, the majority of defect engineering studies for photocatalytic applications are limited to Zr-based MOFs, and there is still a lack of interrelation between synthetic variables, the resultant MOF properties, and their effect on their photocatalytic performance. We report a comprehensive study on the defect engineering of the titanium heterometallic MOF M…
Financial institutions’ risk profile and contribution to the sustainable development goals
2021
This study analyses the impact of Spanish financial institutions’ risk profile on their contribution to the 2030 Agenda. Financial institutions play a significant role in ensuring financial inclusion and sustainable economic growth and usually incorporate environmental and social considerations into their risk management systems. The results show that financial institutions with less capital risk, with lower management efficiency and with higher market risk usually make higher contributions to the Sustainable Development Goals (SDGs), according to their sustainability reports. The novel aspect of the present study is that it identifies the risk profile of financial institutions that incorpo…
Use and misuse in the application of the phytoplankton functional classification: a critical review with updates
2008
Since its publication, the article ‘Towards a functional classification of the freshwater phytoplankton’ (Reynolds et al., J Plankton Res 24: 417–428, 2002), has attracted the attention of dozens of phytoplankton ecologists worldwide. These numerous applications of the functional classification to describe phytoplankton patterns in various aquatic ecosystems allowed the recognition of some uncertain features of this concept originating from various reasons. In this article, we attempt to facilitate the application of the functional classification, by providing a detailed description of the typical misplacements and by modifying some of the original habitat templates and species allocations.…
