Lyocell union fabrics, namely lyocell/silk and lyocell/polyester fabrics, were woven in different fabric constructions and dyed with reactive dyes, acid dyes and a disperse dye. The resulting dyed fabrics were given a resin finishing treatment and their wash fastness was measured. With appropriate dye selection and co…
Abstract Hydrophobically stabilized near‐IR fluorescence from self‐assembled nanoprobes composed of amphiphilic poly(maleic anhydride‐alt‐octadec‐1‐ene) (PMAO) and lipophilized squaraine dopants is reported. From comparative studies with varying lipophilicity of squaraine dyes as well as of nanoparticulate polymer mat…
We apply recently developed techniques for pattern recognition to construct a generative model for chemical structure. This approach can be viewed as ligand-based de novo design. We construct a statistical model describing the structural variations present in a set of molecules which may be sampled to generate new str…
Stimuli-responsive polymers, also called smart materials or intellectual materials, show an interesting property change behavior to external stimulus. These external stimuli, including pH [1,2], temperature [3-6], light [7,8], magnetic and electric field [9,10], and solvent/salt [11,12], result in a change of the poly…
Abstract Inductively heated iron oxides mixed with solid oxidants like CrO2 and NiO2 efficiently oxidize organic substrates under flow conditions in fixed‐bed reactors.
Nature offers a range of colour displays which are relatively short‐lived and which were for many centuries little understood. Today we can explain most which arise from diffraction and reflection effects on rays of sunlight, various atmospheric ionisation phenomena and many colour effects resulting from biochemical r…
Abstract A facile route to prepare lithium niobate (LiNbO 3 ) powders was proposed by an alternative solid‐state method. Stoichiometric Li 2 C 2 O 4 and ammonium niobium oxalate were mixed with small amounts of water and then dried at room temperature. It was demonstrated that Li[NbO(C 2 O 4 ) 2 ]· n H 2 O intermediat…
Abstract We report the synthesis and X‐ray characterization of N9‐ and N6‐decyladenine hydrochloride salts. The latter exhibits interesting anion–π interactions, which are responsible for crystal packing. In contrast, the former does not present any anion–π interactions; the anion is stabilized by hydrogen‐bonding int…
Solution processable organic thin-film transistors (OTFTs) have attracted great attention recently due to their high potentials to dramatically reduce the manufacturing cost for large-area and flexible electronic devices. However, most high performance polymeric semiconductors require chlorinated solvents for their de…
Seeing is believing: Nanoparticle crystals and core–shell crystals detect and amplify the presence of chemical and enzymatic analytes. These crystals are made insoluble in water by cross-linking their surface with dithiols incorporating analyte-specific groups. Upon addition of an analyte, these groups are cut, and th…
We study the optical emission of single GaAs quantum dots (QDs). The QDs are fabricated by filling of nanoholes in AlGaAs and AlAs which are generated in a self-assembled fashion by local droplet etching with Al droplets. Using suitable process parameters, we create either uniform QDs in partially filled deep holes or…
Solvent-based synthetic methods of fullerene nano/microstructures are known to enhance and utilize unique optical and electrical properties of fullerene structures. Here, we report the systematic synthesis and characterization of various-shaped fullerene microcrystals using alcohols as antisolvents in drowning-out cry…
The turbulent impurity (nickel) transport dependence on the normalized electron temperature gradient has been analyzed in sawtooth-free electron cyclotron wave heated Tore Supra plasmas. In the core, our experimental analysis shows that the lower R/L((T)(e)), the lower the nickel diffusion coefficient. The latter decr…
We study the molecular mechanisms of alkali halide ion interactions with the single-wall carbon nanotube surface in water by means of fully atomistic molecular dynamics simulations. We focus on the basic physical-chemical principles of ion-nanotube interactions in aqueous solutions and discuss them in light of recent…
Organozinc addition reactions were carried out on an aldehyde within a porous coordination network (see picture) in a single-crystal-to-single-crystal fashion, and the product structure was unambiguously determined by X-ray diffraction. Moreover, a one-pot two-step reaction in a single crystal furnished an ester from…
Volume x-ray gratings consisting of a multilayer coating deposited on a blazed substrate can diffract with very high efficiency even in high orders if diffraction conditions in-plane (grating) and out-of-plane (Bragg multilayer) are met simultaneously. This remarkable property however depends critically on the ability…
Neue High-Spin-Pfade: Die vier plausiblen Reaktionspfade der Alkanhydroxylierung durch Nichthäm-Eisen(IV)-Oxo-Komplexe wurden rechnerisch untersucht. Der Triplett-σ-Pfad ist energetisch zu hoch, um an einer C-H-Aktivierung beteiligt zu sein – jedoch konkurriert die Reaktivität des Quintett-π-Kanals mit dem Triplett-Pf…
We study the proximity effect in ${\text{SF}}^{\ensuremath{'}}(\text{AF}){\text{F}}^{\ensuremath{'}}\text{S}$ and ${\text{SF}}^{\ensuremath{'}}(\text{F}){\text{F}}^{\ensuremath{'}}\text{S}$ planar junctions, where S is a clean conventional ($s$-wave) superconductor, while ${\text{F}}^{\ensuremath{'}}$ and middle layer…
By control of in situ ligand reaction, two zinc metal−organic frameworks ( 1, 2 ) have been isolated hydrothermally. Both complexes are 3D open frameworks. Complex 1, which is based on an unprecedented {Zn 8 O 13 } SBU constructed of 2 H -imidazole-4,5-dicarboxylic acid (H 3 IMDC), has the same topology as that of MOF…
Many emerging fields such as biotechnology and renewable energy require functionalized surfaces that are "smart" and highly stable. Surface modification schemes developed previously have often been limited to simple molecules or have been based on weakly bound layers that have limited stability. In this Account, we re…
