The thermal phase behaviour of cryomilled α′-AlD3 and α-AlD3 was investigated by in situsynchrotron powder X-ray diffraction (SR-PXD), differential scanning calorimetry and first principles atomic modelling. In situ measurements showed that α′-AlD3 decomposes directly into Al and D2 at around 80 °C during heating at 1…
We have previously reported furan-maleimide Diels-Alder chemistry as a new methodology to couple maleimide-modified antibodies on furan-functionalized polymeric carriers in the preparation of immuno-nanoparticles for targeted drug delivery. In this report, we focus on the characterization, self-assembly behavior and d…
Abstract Stable organic open-shell systems have attracted much attention in the field of molecule-based magnetism. We have been exploring novel stable neutral radicals based on a phenalenyl system known as an odd-alternant hydrocarbon π-radical with a highly spin-delocalized nature. Recently, we have designed and synt…
The preparation and formation mechanism of n-hexadecane/water emulsions using natural beta-cyclodextrin (beta-CD) and chemically modified beta-CDs (triacylated beta-cyclodextrins) as an emulsifier were investigated. The stable water/oil (W/O) emulsion was formed using tripropanoyl-beta-CD (TP-beta-CD). From observatio…
H(2)TFcP [TFcP = 5,10,15,20-tetraferrocenyl porphyrin(2-)] was prepared by a direct tetramerization reaction between pyrrole and ferrocene carbaldehyde in the presence of a BF(3) catalyst, while the series of MTFcP (M = Zn, Ni, Co and Cu) were prepared by a metallation reaction between H(2)TFcP and respective metal ac…
A new class of sorbent material, which exhibits exceptional metal capture from contaminated natural water, features aromatic thiol ligands reversibly bound to functionalized mesoporous silica through non-covalent interactions and have the potential of being regenerable.
A simple approach is described for the preparation of chitooligosaccharide-based giant vesicles with variable size by simply tuning the water content in the water-dioxane mixture, by which reactive vesicles with diameters in the range of 0.5-400 microm were easily prepared.
Liquid-crystalline methanofullerodendrimers were synthesized via the Bingel addition reaction of mesomorphic malonate derivatives and C60. Second- and third-generation poly(benzyl ether) dendrons were selected as liquid-crystalline promoters to induce columnar mesomorphism. Based on a convergent and modular synthetic…
SrTiO 3 films were grown by reactive molecular beam epitaxy to have varying degrees of both global and local cationic nonstoichiometries (with stoichiometry defined as a 1:1 ratio of Sr:Ti). Slight global excesses of Sr and Ti resulted in two-fold reconstructions in the reflection high-energy electron diffraction patt…
A self-assembled tetrameric water cluster stabilized by [ReCl6]2− anions and [H4biim]2+ cations occurs in the new compound [H4biim][ReCl6]·4H2O, which exhibits a weak ferromagnetic coupling between the Re(IV) centers through an unusual ReIV–Cl⋯(H2O)⋯Cl–ReIV pathway.
Photochromic superabsorbent polymers (PSAPs) with a hydrophilic core and a photochromic shell were prepared by inverse suspension polymerization using acrylic acid (AA) and acrylamide (AM) as monomers, potassium persulfate as the initiator, N,N'-methylene bisacrylamide (BIS) as a cross-linker, sorbitan monostearate (S…
We used a CO2 laser as a heat source to avoid thermodegradation in the melt-electrospinning process (termed “laser electrospinning” (LES)). Nylon 6, polypropylene, poly (ethylene terephthalate) and poly (L-lactide-co-ε-caprolactone) fiber webs were prepared by the LES. For Nylon 6 and poly (L-lactide-co-ε-caprolactone…
We demonstrate a simple vapor-phase fabrication of self-assembled perpendicular organic nanoneedles on various substrates to generate superhydrophobic surfaces on them.
Smectite like layered silicates with cation exchange capacity ranges from 60 to 90 mequivalent/100g clay were synthesized from LiF, Mg(OH)2 and colloidal silica. The controlled cation exchange capacity achieved by changing the composition of the starting mixture (namely the added LiF amount) successfully influenced th…
The effect of mechanical stirring on the morphology of hexagonal layer‐structure birnessite nanoparticles produced from decomposition of KMnO 4 in dilute aqueous H 2 SO 4 is investigated, with characterization by X‐ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high‐…
Since the last decade, most research focus in the fields of science and engineering has been dramatically shifted toward the same fashion from the investigation of traditional macroscale properties of materials to their atomic scale level (or called nanoscale). It is believed that the mechanical, electrical and therma…
The epoxy nanocomposites filled with 0.1, 0.5, and 1 wt% nanodiamonds (nanoD) were prepared and their properties were compared with neat epoxy network or epoxy nanocomposite filled with 1 wt% multiwalled carbon nanotubes (MWCNTs). The obtained nanoD-epoxy composites increased significantly thermal stability of prepare…
We report localized surface plasmon resonance (LSPR) of hexagonal Au nanodot arrays to detect changes in the thickness and conformation of poly[2-(methacryloyloxy)ethyltrimethyl ammonium chloride] (PMETAC) brushes.
High-yield bamboo-shaped carbon nanotubes (BCNTs) have been produced by using cresol as the precursor, for the first time and there are almost no straight CNTs or amorphous carbon found in the product: the role of cresol in promoting the growth of BCNTs is discussed; improved cycle stability and electric conductivity…
The luminescence of cerium(III) has been studied in aqueous solutions in the presence of acetate ion. In contrast to previous reports that cerium(III) carboxylate complexes do not luminesce, a weak emission is observed, which has a similar spectrum to the aquo cerium(III) species but a much shorter lifetime. Results f…
