The properties of PHB may be affected by the carbon source used in its production and this may affect nanofibres made from this polymer by electrospinning. In this study, P(3-HB) was produced from glucose, rapeseed oil, and olive oil by Ralstonia eutropha H16. Cell growth and polymer production were higher in olive or…
The normalized gel fraction <italic>versus</italic> the normalized crosslink density of the decrosslinked 1% (a), 2% (b) and 4% (c) XHDPE. Dotted and dashed lines represent Horikx function fits, respectively.
With their unique ability for substrate recognition and their sequence-specific self-assembly properties, peptides play an important role in controlling the mineralization of inorganic materials in natural systems and in controlling the assembly of soft materials into complex structures required for biological functio…
The structure and formation energies of cation antisite defects for a series of stannate pyrochlores A 2 Sn 2 O 7 (A = La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Lu, and Y) and titanate pyrochlores A 2 Ti 2 O 7 (A = La, Sm, Gd, Tb, Dy, Ho, Er, Lu, and Y) have been systematically investigated using the first-principles to…
A remarkable difference in thermal desorption spectra of hydrogen obtained from pre-strained high-strength steel specimens which were charged with hydrogen by two different methods was observed. One charging method is by immersion in NH4SCN solution and the other is by cyclic corrosion tests. In order to understand th…
NO adsorption, diffusion and reaction at reduced CeO2(110) were studied by density functional theory calculations. NO accommodated by O vacancies can readily diffuse via alternate NO2 formation and dissociation, facilitating N2O2 formation and subsequent reduction to N2. Rare earth ceria plays an important catalytic r…
We present the synthesis and characterization of a series of four fluorescent Sn(iv) Schiff base complexes, which also possess long-lived triplet excited states. The complexes absorb visible light (λmax = 420 to 462 nm) and the optical properties are easily tunable without laborious synthetic elaboration. The triplet…
Both classical and quantum mechanical simulation techniques have been applied to investigate the incorporation, migration and potential binding of protonic defects in bulk yttria-stabilised zirconia (YSZ). The calculated redox reaction energies are found to be high, although the reduction energies are lower than those…
Composite conductive fibers based on poly(3,4-ethylenedioxythiophene)-polystyrene sulfonic acid (PEDOT-PSS) solution blended with polyacrylonitrile (PAN) were obtained <italic>via</italic> wet spinning.
The first representative of functionalized fluoroalkyl phthalocyanines, F48H7(COOH)PcZn, is reported. The complex generates (1)O2 affording long-lasting photooxidation of an external substrate without self-decomposition. The carboxylic group couples with an antisense oligonucleotide targeting GRP78 oncogenes, resultin…
Mixed-metal amidoborane would play an important role in suppressing the emission of by-product gases from AB–MAlH <sub>4</sub> (M = Na, Li) composites.
A facile one pot strategy for the preparation of linear and hyperbranched polyacrylates has been successfully developed by the combination of in situ esterification of acrylic acid with halogenated compounds promoted by 1,1,3,3-tetramethylguanidine (TMG) and RAFT polymerization.
Many high permittivity crystalline dielectric thin films have a low breakdown strength, which is unfavorable for dielectric energy storage devices. In contrast, many amorphous linear dielectrics have much lower permittivities but larger breakdown strengths. Here, composite thin films with nanocrystalline particles in…
The interaction between H <sub>2</sub> molecule and B/C/N sheet is Kubas interaction under an external electric field.
Despite voluminous research on the acid oxidation of carbon nanotubes (CNTs), there is a distinct lack of experimental results showing distributions of functional groups at the nanometre length scale. Here, functional peaks have been mapped across individual multi-walled CNTs with low-dose, monochromated electron ener…
An anti-galvanic reduction method using [Ag62S13(SBut)32]4+ nanoclusters as the metal ion probe for detecting Cu2+ is reported here. We found [Ag62S13(SBut)32]4+ can reduce more reactive Cu2+ with a quantitative relationship. The single molecule fluorescence imaging shows that Ag62 NCs could be used as a single molecu…
trans-4-Hydroxy-l-proline (T4LHyp) and trans-3-hydroxy-l-proline (T3LHyp) occur mainly in collagen. A few bacteria can convert T4LHyp to α-ketoglutarate, and we previously revealed a hypothetical pathway consisting of four enzymes at the molecular level (J Biol Chem (2007) 282, 6685-6695; J Biol Chem (2012) 287, 32674…
Cu‐doped‐CdS and In‐doped‐CdS cosensitized (Cu‐doped‐CdS/In‐doped‐CdS) quantum dot solar cells (QDSCs) are introduced here. Different cosensitized sequences, doping ratios, and the thickness (SILAR cycles) of Cu‐doped‐CdS and In‐doped‐CdS are discussed. Compared with undoped CdS QDSCs, the short circuit current densit…
Novel diarylethenes containing triphenylamine units have been synthesized and characterized, and possessed both photochromic and electrochromic properties.
Stress engineering is becoming an increasingly important method for controlling electronic, optical, and magnetic properties of nanostructures, although the concept of stress is poorly defined at the nanoscale. We outline a procedure for computing bulk and surface stress in nanoparticles using atomistic simulation. Th…
