The role of nanoparticle concentration and CNT coating in high-performance polymer-free micro/nanostructured carbon nanotube-nanoparticle composite electrode for Li intercalation
No full textWe investigate how Li intercalation into composite electrodes resulting
from the combination of graphitic carbon felt (CF) with carbon nanotubes
(CNTs) functionalized with electroactive nanoparticles (NPs) depends on
NP concentration. To this end, we study CF electrodes coated or not with
hydrophilic CNTs containing electrodeposited beta/gamma-MnO(2)NPs (wt%
25, 42, and 69) with hollow-nanotube structure. Galvanic coupling
between the CNTs and the NPs is the reason why the electrochemical
performance of CNT-NP nanocomposites varies with the NP concentration.
The CNT coating on the CF electrode also avoids capacity fading of the
CF/MnO2NP electrodes and prevents carbon fibers from interconnecting
with SEL More specifically, the CNTs stabilize the solid electrolyte
interphase and prevent NP detachment, thereby producing electrodes with
long-term cyclability. The best electrochemical performance occurs for
CNT/MnO2NP mass wt% 25 (1114 mAh g(-1), 1st discharge/charge Faradaic
efficiency similar to 80% at 1 A g(-1), cut-off potential = 4-0.005 V

Opposition to the unjust policy and oppression Kazakh people began to protest and this led to brutal genocide and forceful migration. At the same time, this novel also covering Russian communist revolution in 1917 and returning back home of the migrant people and their social life until the end of Soviet Union in 1991. In this novel, the author has written a wide range of genres and very long period of time. A part of the novel is based on documents which recorded at the time of these events. Some parts of the novel were written depending on documents which was described events occurring in 1916 and migrations during these period. Sections of the novel which were describing the events of after migration and back home are entirely the author’s fiction. The inadequacy of the depictions of the people and places, as well as many incidents which took place at that time covered by the novel are among the reasons for this technical weakness. © 2021, Ahmet Yesevi University.

An Example of National Romanticism in Contemporary Kazakh Literature an Assessment of the Novel Ey, Dunye Ey

Dual-Emitting EY@Zr-MOF Composite as Self-Calibrating Luminescent Sensor for Selective Detection of Inorganic Ions and Nitroaromatics
No full textA dual-emitting
dye@MOF composite has been synthesized by incorporating
a fluorescent dye eosin Y (EY) within a UiO-type zirconium-based metal–organic
framework (Zr-MOF) through a synthetic encapsulation method. The Zr-MOF
prevents the aggregation of EY molecules and keeps EY molecules stably
included after synthesis. As expected, an energy transfer from Zr-MOF
to EY molecules occurred because of the good overlap between the emission
of Zr-MOF and the absorption of EY. As a result, the obtained EY@Zr-MOF
composite features a weak blue emission at 446 nm and a strong yellow
emission at 553 nm. By using the relative height of the two emission
peaks replacing absolute peak height as detecting signals, EY@Zr-MOF
composite acts as a self-calibrating luminescent sensor for selectively
detecting Fe3+, Cr2O72–, and 2-nitrophenol. Furthermore, the observed fluorescence responses
of the composite toward analyte are highly stable and reversible after
recycling experiments. To the best of our knowledge, this is the first
example of a dye@MOF-implicated self-calibrating sensor for Fe3+, Cr2O72–, and 2-nitrophenol
detection
Le Bouvard et Pécuchet d'Henri Ey (1955)
No full textinterprétation historique d'un pastiche de "Bouvard et Pécuchet" de Flaubert, écrit par un psychiatre francais en 1955. Pour accéder à la source: http://flaubert.univ-rouen.fr/article.php?id=25In 1955, psychiatrist Henri Ey (1900-1977) edited a Treaty of Psychiatry (Traité de Psychiatrie) as part of the Medical-Chirurgical Encyclopedia (Encyclopédie Médico-Chirurgicale, EMC, Editions Techniques), gathering more than a hundred collaborators. A large portion of these were from the French psychoanalytic community and psychiatrists affiliated with public psychiatric hospitals, however excluding the main characters of academic neuropsychiatry. At a banquet organized to celebrate the publication of the contributed volume, Henri Ey reads to his guests a parody of Bouvard and Pécuchet by Flaubert. I suggest to grasp this relatively little-known manuscript under the lens of irony. Written in a derisive manner by a psychiastrist mocking the practices and doctrines of his field (from mesmerism to Freudianism), this document may also be appraised as a roman à clef about the balance of powers and struggles for monopoly within a medical profession where dissent is being fueled by distinct professional titles, intellectual itineraries or scientific networks. I will first show that Henri Ey probably relied on the "deux bonshommes" to neutralize any form of criticism against his ambition to be an encyclopedist. Henri Ey's attitude may here be compared with that of Raymond Queneau (1903-1976), at the time director of the Encyclopédie de la Pléiade: he, too, was haunted by the characters of the mad professor and the amateur scientist, and he wrote two prefaces for reissues of Bouvard and Pécuchet. However, Henri Ey's Bouvard and Pécuchet is less evocative of Queneau's stylistic composition than the pugnacity of corporatist manuscripts defending psychiatry. In a second step, I will analyze the status of the burlesque pastiche of an already burlesque work: this text hides an authentic satire featured as a comedy. The author targets a number of real individuals, sometimes named in the text and represented in a grotesque manner. Here, parody appears to be serving persiflage.En 1955 le psychiatre Henri Ey (1900-1977) publie sous sa direction un Traité de Psychiatrie dans la collection de l'Encyclopédie Médico-Chirurgicale (EMC, Editions Techniques), rassemblant autour de lui plus d'une centaine de collaborateurs. Parmi eux, une grande partie des psychanalystes français, avec qui les psychiatres du cadre des hôpitaux psychiatriques publics se répartissent les matières à exposer, tandis que les principaux représentants de la neuropsychiatrie universitaire sont exclus. Lors d'un banquet offert pour fêter la parution de l'ouvrage collectif, Henri Ey fait la lecture à ses hôtes d'une parodie (ou pastiche, voire satire ?) de Bouvard et Pécuchet de Flaubert. Je propose d'appréhender ce document méconnu des historiens par le biais de l'ironie : écrit sur le ton de la dérision par un psychiatre évoquant les pratiques et les doctrines qui prêtent le flan à la moquerie dans sa discipline (du mesmérisme au freudisme), le texte peut aussi se lire comme un roman à clef des rapports de force et des défenses de monopole, dans une profession médicale où les dissensions sont nourries par des titres professionnels, par des itinéraires intellectuels et par des réseaux savants différents. Dans un premier temps, je montrerai qu'à travers l'emprunt des " deux bonshommes ", Henri Ey avait certainement pour but de désamorcer toute critique vis-à-vis de son ambition d'encyclopédiste. On peut comparer à cette occasion la posture d'Henri Ey à celle de l'écrivain Raymond Queneau (1903-1976), directeur de l'Encyclopédie de la Pléiade à la même époque : lui aussi fut hanté par les figures du savant fou et du scientifique amateur et il rédigea deux préfaces pour des rééditions de Bouvard et Pécuchet. Cependant, le Bouvard et Pécuchet d'Henri Ey évoque moins l'exercice de style de Queneau que la pugnacité des textes corporatistes de défense de la psychiatrie. Dans un second temps, il s'agira donc d'analyser le statut de l'imitation burlesque d'une œuvre déjà burlesque : ce texte cache une véritable satire sous le travestissement du comique. L'auteur vise une série de personnes bien réelles, parfois nommées dans le texte et présentées de manière grotesque. La parodie apparaît ici comme mise au service du persiflage
Nanostructured V2O5.nH2O/cup-stacked carbon nanotube composite with remarkable Li+ specific capacity
No full textNanostructures for lithium intercalation can be obtained by combining carbon nanotubes with nanoparticles, to achieve a composite that can be applied as electrochemical energy storage device. Depending on the chemical composition and architecture of the nanostructure, it can be used to develop batteries, supercapacitors, or hybrid battery-supercapacitor devices. Here, we study how the V2O5.nH2O concentration affects lithium intercalation into the V2O5.nH2O/cup-stacked carbon nanotube (CSCNTs) nanostructure. First, CSCNTs were directly grown on the surface of a nonwoven carbon fiber felt (CF). Then, ε/δ-V2O5.nH2O was electrodeposited on the CF/CSCNT composite. Between 4.2 and 1.5 V, 34 wt% V2O5.nH2O load provided lithium specific capacity of 633 mAhg−1 at 0.5 Ag−1 for 300 discharge/charge cycles with lower fading capacity. Higher or lower V2O5.nH2O load diminished this performance. Depending on the V2O5.nH2O load and scan rate, this new nanostructure can also operate as a pseudo-capacitor, to deliver 610 F g−1 at a scan rate of 10 mV s−1 between 4.0 and 1.5 V. We discuss this dependence in terms of V2O5.nH2O morphology and the presence of a junction between CSCNTs and V2O5.nH2O
