We report analysis of chemical durability of UK HLW MW +25% simulant glass under model hyperalkaline conditions of a colocated geological disposal facility. Glass powders and monoliths were dissolved for 168 days in saturated Ca(OH) 2 . Dissolution in the presence of high concentrations of Ca (>200 mg/L) was an order…
We propose an approach based on the combination of different techniques in order to discriminate various reinforcement effects in vulcanized natural rubber elastomers with various cross-link densities, filled with carbon black or silica: mechanical response, independent measurements of the cross-link density by proton…
In the present work, a systematic study of the release kinetics of two embedded model drugs (one completely water soluble and one partially water soluble) from hydrophilic and hydrophobic nanofiber mats was conducted. Fluorescent dye Rhodamine B was used as a model hydrophilic drug in controlled release experiments af…
A biscalixarene framework, without long alkyl chains, has been readily synthesized in three steps starting from the parent calix[4]arene. The biscalix[4]arene 1 was able to form organogels in various alcoholic solvents; furthermore, it exhibited an excellent phase selective gelation property that is potentially useful…
The semiring chemistry of the Au25(SR)18, particularly its fragmentation mechanism and catalytic active site, is explored using density functional theory (DFT) calculations. Our calculations show that the magically stable fragmental cluster, Au21(SR)14(-), as detected in several mass spectrometry (MS) measurements of…
It is currently very urgent to develop flexible energy storage devices because of the growing academic interest in and strong technical demand of flexible electronics. Exploration of high-performance electrode materials and a corresponding assembly method for fabrication of flexible energy storage devices plays a crit…
The physics of nickel perovskites is rich with various competing electronic phases that can be tuned by chemical or external degrees of freedom. As such, nickelates show strong potential for oxide electronics devices based on strongly correlated systems. However, their complexity has hitherto challenged a detailed und…
In this feature article, brief highlights of research progress on the linear neutral platinum-acetylide moiety, trans-Pt(PR3)2(C≡CR')2, are presented. Due to its unique characteristics such as the well-defined linear geometry, synthetic accessibility, and intriguing photoproperties, this type of platinum-acetylide moi…
Wheat gluten (WG) and its components, gliadin and glutenin proteins, form the largest polymers in nature, which complicates the structural architecture of these proteins. Wheat gluten, gliadin and glutenin proteins in unmodified form showed few secondary structural features. Structural modification of these proteins u…
The 3d-series transition metals (also called the fourth-period transition metals), Sc to Zn, are very important in industry and biology, but they provide unique challenges to computing the electronic structure of their compounds. In order to successfully describe the compounds by theory, one must be able to describe t…
Barium titanate (BaTiO3) nanowires have gained considerable research interest due to their lead-free composition and strong energy conversion efficiency. However, most research has focused on free-standing BaTiO3 nanowires, which are hard to apply for sensing and energy harvesting. Here, a novel method for the growth…
Quantitative X-ray powder diffraction analysis demonstrates that mixing Ti, Zr and Hf on the ionic site in the half-Heusler structure, which is a common strategy to lower the lattice thermal conductivity in this important class of thermoelectric materials, leads to multiphase behaviour. For example, nominal Ti0.5Zr0.5…
Abstract A new magnetic–fluorescent bifunctional coaxial nanobelt structure has been successfully fabricated by specially designed coaxial‐spinneret electrospinning technology. As an example, terbium complexes [Tb(BA)3(phen)] (BA=benzoic acid, phen=1,10‐phenanthroline) and ferroferric oxide nanoparticles were incorpor…
We report the synthesis of a Au44(SR)28 nanocluster (SR = 4-tert-butylbenzenethiolate). Based on the structural rules learned from the known Au28(SR)20 and Au36(SR)24 structures, we propose a plausible structure for Au44(SR)28, which is predicted to comprise a six-interpenetrating cuboctahedral Au36 kernel protected b…
A lanthanide complex-based ratiometric luminescence probe, [4'-(2,4-dinitrobenzenesulfonyloxy)-2,2':6',2''-terpyridine-6,6''-diyl] bis(methylenenitrilo) tetrakis(acetate)-Eu(3+)/Tb(3+) (NSTTA-Eu(3+)/Tb(3+)), has been designed and synthesized for the specific recognition and time-gated luminescence detection of biothio…
A series of phosphorescent cyclometalated iridium(III) polypyridine complexes appended with a β-D-glucose moiety [Ir(N^C)2(bpy-TEG-ONCH3-β-D-glc)](PF6) [bpy-TEG-ONCH3-β-D-glc = 4-(10-N-methyl-N-(β-D-glucopyranosyl)-amino-oxy-2,5,8-trioxa-dec-1-yl)-4'-methyl-2,2'-bipyridine; HN^C = 2-((1,1'-biphenyl)-4-yl)benzothiazole…
The current status of research on the electronic properties of filled single-walled carbon nanotubes (SWCNTs) is reviewed.SWCNT atomic structure and electronic properties are described, and their correlation is discussed.Methods for modifying the electronic properties of SWCNTs are considered.SWCNT filling materials a…
The magnetic properties of the mononuclear manganese(III) complex [Mn{(OPPh2)2N}3] are investigated by means of magnetometry and dual-mode X-band electron paramagnetic resonance spectroscopy. Slow relaxation of magnetization is induced in the presence of external magnetic fields.
In this paper, we use a simple device architecture based on solution-processed ZnO nanoparticles (NPs) as the electron injection/transport layer and bilayer structure of poly(ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS)/poly[9,9-dioctylfluorene-co-N-[4-(3-methylpropyl)]-diphenylamine] (TFB) as the hole in…
The effect of the type of chemical route used to functionalize graphene with short-chain polyethylene on the final properties of graphene-based high density polyethylene nanocomposites is reported. Three different click reactions, namely copper-catalyzed alkyne–azide (CuAAC), thiol–ene and thiol–yne have been addresse…
