Abstract Stoichiometric polyelectrolyte complexes (PECs) of the strong polyelectrolytes poly(styrenesulfonate) (PSS) and poly(diallyldimethylammonium) (PDADMA) were dissociated and dissolved in aqueous KBr. Water was added to dilute the salt, allowing polyelectrolytes to reassociate. After appropriate equilibration, t…
We report the synthesis of heterodimensional nanostructures of MoS2 quantum dots interspersed in few-layered sheets of MoS2, using a liquid exfoliation technique in organic solvents. This unique hybrid morphology results from the optimized experimental conditions involving bath sonication followed by ultrasound probe…
Finding an ideal model for disclosing the role of oxygen vacancies in photocatalysis remains a huge challenge. Herein, O-vacancies confined in atomically thin sheets is proposed as an excellent platform to study the O-vacancy-photocatalysis relationship. As an example, O-vacancy-rich/-poor 5-atom-thick In2O3 porous sh…
We present angle-resolved photoemission studies on the rare-earth hexaboride YbB$_6$, which has recently been predicted to be a topological Kondo insulator. Our data do not agree with the prediction and instead show that YbB$_6$ exhibits a novel topological insulator state in the absence of a Kondo mechanism. We find…
Résume: Nous sommes venues à travers notre travail, qui inclut dans l’étude du comportement rhéologique du complexe (AD37-P4VP-DPC). On prouve, la viscosité dynamique peut être affectée par la présence et en absence de sel (phénomène d’écrantage), ce qui réduit les interactions et les répulsions électrostatiques entre…

Understanding the nature of metal/1D-semiconductor contacts such as metal/carbon nanotubes is a fundamental scientific and technological challenge for realizing high performance transistors\cite{Francois,Franklin}. A Schottky Barrier(SB) is usually formed at the interface of the $2D$ metal electrode with the $1D$ semi…

In this paper we analyse the importance of a detailed description of the electronic transitions in ultra-small nanoparticles through the optical response to very small changes of size in systems, whose dimensions are in the subnanometric scale. We present a carefully calculation of the optical response of these system…
The 0.3Li2MnO3 x 0.7LiMn0.60Ni0.25Co0.15O2 cathode materials were synthesized using a coprecipitation method at a various heat-treatment temperature. From XRD pattern analysis, pure layered structure without impurities was confirmed from all samples and the peak intensity of Li2MnO3 was increased as the heat-treatment…
Copper (Cu) coated carbon nanotubes (CNTs) were prepared and investigated by chemical reduction or cementation method. The morphology changes of Cu nanoparticles deposited onto the multiwall carbon nanotubes with metallic zinc (Zn) as a reducing agent have been examined at different cementation factors. The precipitat…
A trilayered dry conducting polymer actuator was fabricated via application of a polypyrrole (PPy) coating on both sides of a solid polymer electrolyte film using vapor phase polymerization (VPP). The solid polymer electrolyte film was prepared by incorporation of different weight ratios of dodecylbenzene sulfonic aci…
Nickel-loaded SiC-alumina structural catalysts containing nanowires were facilely fabricated via modified sol-gel process mediated by supercritical carbon dioxide, followed by thermal-treatment. The nanowires were formed by metal-catalyzed growth on the outer and inner parts of SiC-alumina nanocomposite beads containi…
The authors describe the fabrication of white organic light-emitting diodes (WOLEDs) with dual electron transporting layers (D-ETL) using 2,9-dimethyl-4,7-diphenyl-1,10-phenanhroline/ 4,7-diphenyl-1,10-phenanthroline (BPhen) and bis-(2-methyl-8-quinolinolate)-4-(phenylphenolato) aluminum/BPhen. Stepwise D-ETL easily t…
We have studied the effect of surface plasmon (SP) coupling to enhance emission efficiency of light emitting diode (LED) with multiple quantum wells (MQWs) structure by positioning Ag nanoparticles on the line-arrayed patterns. The line-arrayed patterns were fabricated by photolithography and inductively coupled plasm…
