The first example deals with the valorization of biomass-derived small platform molecules, and in particular the implementation of a deoxydehydration (DODH) reaction of glycerol towards allyl alcohol under continuous-flow conditions. The combination of a unique reactive dynamic feed solution approach and short exposure to high temperature gave high yield and excellent selectivity in the presence of formic acid, triethyl orthoformate, or a combination of both. The second example deals with the preparation of large bio macromolecules, and in particular the implementation of chemical native ligation towards peptide constructs under continuous-flow conditions. The combination of the unique assets of microfluidic reactors and the development of new reagents/conditions were exploited to perform extremely fast ligations at difficult junctions that are notoriously time-consuming. Ligation times down to 2 min were achieved, with excellent conversion and overall isolated yields for a range of macrocylic peptides bearing up to 29 residues. The reaction conditions were also amenable, upon minor adjustments, to less hindered junctions.

Accurate control over local process parameters, even under extreme conditions, inherent safety, production homogeneity and seamless scale-up are amongst the most important assets of continuous-flow chemistry. Besides, flow chemistry enables the design of efficient multistep processes with significantly reduced footprints. In this lecture, we will discuss some of the most fascinating aspects of continuous-flow micro- and mesofluidic reactors in the specific context of preparative organic chemistry. Multiple examples illustrating the development and implementation of continuous-flow multistep strategies for the synthesis of high-value added organic targets will be presented.

Na-ion batteries are considered to be an alternative to Li-ion batteries owing to the natural abundance of sodium. New electrode materials are required to increase the energy density of Li/Na-ion batteries. In this study, we show that the addition of the carbon sources during the synthesis leads to control the particles size and morphology and improve their conductivity properties that enhance the electrochemical performance [1-5]. In order to study the effect of the carbon on the structural, morphological and electrochemical properties of the prepared materials by a spray-drying [1-3] or hydrothermal methods [4, 5]. The crystal and local structure were analyzed by XRD and Mössbauer spectroscopy. The morphological properties were characterized by SEM and TEM. The carbon content was determined by TG/TDA and carbon analyzer. The electrochemical properties were studied by impedance spectroscopy and galvanostatic cycling in lithium cells. Finally, the reaction mechanism during cycling was investigated using operando XRD technique. 1- A. Mahmoud, S. Caes, M. Brisbois, R.P. Hermann, L. Berardo, A. Schrijnemakers, C. Malherbe, G.

It could be thought that this distance changes the perception managers have of work constraints and resources. This study attempts to tackle staff and leadership disparate views on the issues facing front-line nursing staff. We sent an online questionnaire on work constraints and good practices to nursing chiefs from Belgium hospitals and conducted focus groups with their ‘front-line’ nursing staff in order to compare perceptions. 40% of the chief nurses mentioned as a regular problems for their staff: production pressure, working time, doctors–nurses collaboration and managing new staff. Except for the ‘productive pressure’, these issues are rather considered by the staff as occasional problems. Front-line staffs evaluate infrastructure, heat, working positions as more common problems. However, statistical analyses showed one significant difference in perception: management of incidents/accidents. Health care organizations should promote participatory management tools both to diagnose work constraints and to elaborate action priorities in order to guarantee a shared understanding of decisions making between staff and supervisors.

Damselfishes have experienced many repeated convergences wherein subclades radiated across similar trophic strategies (i.e. pelagic foragers, benthic feeders, and an intermediate group) and similar morphologies. The presence of evolutionary convergences in damselfishes was recently highlighted by the combination of ecological and morphological data, and the use of phylogenetic comparative methods. Nevertheless, many other aspects of these replicated sets of lineages remain unexplored. For example, little is known about the functional diversity of assemblages including convergent lineages that emerged from iterative processes of ecological radiation, or which of the niche-related processes and phylogenetic conservatism are the major factors shaping these assemblages. Here, we conducted a quantitative comparison of these processes in damselfish assemblages that belong to three distinct Indo-Pacific coral reefs differing in taxonomic composition, morphology and degree of human disturbance. Using various metrics, we compared the functional diversity (based on a dataset of eight functional traits) and the isotopic diversity (a proxy of trophic diversity) among assemblages, grasping many aspects of the eco-functional diversity of Pomacentridae. We also tested whether these eco-functional traits displayed some evolutionary conservatism. Our results demonstrate that the eco-functional diversity of damselfishes follows similar patterns among Indo-Pacific coral reefs. The trophic space remains equivalent despite gradient in species richness, whereas the number of functional entities occupied by taxa dictates the size of the functional space. In each assemblage, eco-functional niches are highly differentiated and evenly distributed in spaces of similar size. The inconsistent phylogenetic structure of eco-functional traits suggests that the similarity in the diversity of damselfish assemblages is mainly driven by niche-based processes and not by phylogenetic relatedness. We suggest that a broader application of our approach will help to uncover the mechanisms of reef fish community assembly over space and time. Fri, 20 Oct 2017 12:41:19 GMT
