In the framework of the successive 1991 and 2006 Waste Management Act, French government supported a very significant R&D program on partitioning and transmutation of minor actinides (MA). This program aims to study potential solutions for still minimizing the quantity and the hazardousness of final waste, by MA recyc…
The cyclic voltammetry at electrodes composed of multiple electroactive materials, where zones of one highly active material are distributed over a substrate of a second, less active material, is investigated by simulation. The two materials are assumed to differ in terms of their electrochemical rate constants toward…
Production of hydrogen from the aluminum and its alloys powder with aqueous alkaline solutions is studied. In this process, it is based on aluminum corrosion, consuming only water and aluminum which are cheaper raw materials than other compounds used for in situ hydrogen generation, such as chemical hydride. In princi…
We synthesised a novel gold-on-porous silicon hybrid material that exhibits a highly sensitive and reproducible surface-enhanced Raman spectroscopy (SERS) response. The material was fabricated simply by reducing gold chloride with hydrofluoric acid on the surface of macro-porous silicon (macro-PSi). The material consi…
Butylmethylpyrrolidinium–dicyanamide (BMP–DCA) ionic liquid (IL), which enables the pseudocapacitive behavior of a MnO2 electrode, performing over a wide potential range of 3 V, is considered to be a promising electrolyte for supercapacitors. Various additives are doped in this IL electrolyte in attempt to further imp…
Boron-doped ordered mesoporous carbons (B-OMCs) were successfully prepared using an in-situ approach via organic-inorganic co-assembly, in which, laboratory-made boron-modified phenolic resins were selected as the carbon precursor, tetraethyl orthosilicate as the inorganic precursor and reverse amphiphilic triblock co…
Highly photoluminescent (PL) CuInZnxS1+x nanocrystals (NCs) and CuInZnxS1+x/ZnS core/shell NCs were successfully synthesized by a facile colloidal method. First, a facile and reliable non-injection method for the synthesis of photoluminescent CuInZnxS2+x NCs was developed with inexpensive reagents. The relative PL qua…
Nanomaterials exhibit distinctive physicochemical properties and promise a wide range of applications from nanotechnology to nanomedicine, which raise serious concerns about their potential environmental impacts on ecosystems. Unlike any conventional chemicals, nanomaterials are highly heterogeneous, and their propert…
We report results of a theoretical study, based on density functional theory (DFT), on the structural, electronic, optical, and chiroptical properties of small thiolated gold clusters, [Au(n)(SR)(m) (n = 12-15, 16-20; m = 9-12, 12-16)]. Some of these clusters correspond to those recently synthesized with the surfactan…
A one-step method was developed for the controllable construction of metal-graphene core-shell structures, hollow graphene nanospheres, and a high density of metal nanoparticles supported on graphene. The metal-graphene core-shell nanostructures as nanocatalysts show excellent catalytic ability for the selective oxida…
By altering the functional groups of tetrazolate ligands in the same Ag–POM reaction system, two novel inorganic–organic hybrids: [Ag7(L1)4(H2O)(PMo12O40)] (1) and [Ag5(L2)2(PMo12O40)]·H2O (2) (HL1 = 5-(4-imidazol-1-yl-phenyl)-2H-tetrazole, HL2 = 5-(4-triazol-1-ylmethyl-phenyl)-2H-tetrazole), have been synthesized und…
Four new tris-substituted bismuth(III) sulfonates of general formula [Bi(O(3)SR)(3)] (R = phenyl 1, p-tolyl 2, 2,4,6-mesityl 3 and S-(+)-10-camphoryl 4) have been synthesised and characterised. Their synthesis by solvent-free (SF) and solvent-mediated (SM) methods has been explored and their activity against Helicobac…
Axially chiral, 3,5-dihydro-4H-dinaphtho[2,1-c:1',2'-e]azepine (dinaphthazepine) and 1,1'-binaphthyl-2,2'-disulfonimide (dinaphthosulfonimide) moieties were rigidly connected via N-p-phenylene linkers to photochemically (E)/(Z)-isomerisable 1,2-diethynylethene scaffolds. The chemical stability of the resulting systems…
Novel three-dimensional patterned carbon nanotube (CNT) arrays with excellent field emission (FE) performance have been fabricated on a flexible carbon cloth substrate by a facile and repeatable two-step process. Firstly, a discrete layer of ZnO nanowire arrays were synthesized on carbon cloth to act as a template for…
Ce(3+), Tb(3+) and Mn(2+)-activated KSrGd(PO(4))(2) phosphors with high absolute quantum efficiencies were first prepared by a Pechini-type sol-gel method. The photoluminescence and cathodoluminescence intensities of Tb(3+)/Mn(2+) can be enhanced by co-doped Ce(3+) ions into the KSrGd(PO(4))(2) host via the energy tra…
This highlight introduces the development of hydrogelators consisting of nucleobases, amino acids, and glycosides (i.e., molecular trinity), or nucleobases and amino acids (i.e., nucleopeptides). These novel small molecule hydrogelators self-assemble in water to form stable supramolecular nanofibers/hydrogels and exhi…
Exponentially growing layer-by-layer hierarchical nanoporous films have been used as a promising system for controlled drug loading/release applications. However, its growth mechanism and factors affecting the drug loading/release are still unclear. In this study, high molecular weight branched poly(ethyleneimine) (PE…
Luminescent mesoporous materials were prepared by performing an anion metathesis reaction on ionic liquid modified SBA15, which has imidazolium chloride bridging units. The lanthanide β-diketonate complex anion was successfully anchored onto the SBA15 framework after the anion metathesis reaction. The resulting materi…
This article reports on the influence of different lanthanides (La, Nd, Gd and Yb) on sintering behavior of alkaline-earth aluminosilicate glass-ceramic sealants for their application in solid oxide fuel cells (SOFCs). All the glasses have been prepared by the melt–quench technique. The in situ follow up of sintering…
Pincer complexes of the type [2,6-(R(2)PO)(2)C(6)H(3)]NiSC(6)H(4)Z (R = Ph and i-Pr; Z = p-OCH(3), p-CH(3), H, p-Cl, and p-CF(3)) have been synthesized from [2,6-(R(2)PO)(2)C(6)H(3)]NiCl and sodium arylthiolate. X-ray structure determinations of these thiolate complexes have shown a somewhat constant Ni-S bond length…
