N-Boryl-substituted carbazoles (carBR(2)) and (diphenylamino)boranes (Ph(2)NBR(2)) with R = Mes (mesityl) and FMes [tris(trifluoromethyl)phenyl] substituents on boron exhibit large UV/vis Stokes shifts. To investigate the substituent effect on the magnitude of the Stokes shifts, we studied the electronic structure and…
Ionically crosslinked chitosan membranes were prepared and their swelling behaviour was analysed. Low‑molecular pentasodium tripolyphosphate (TPP) and/or high‑molecular sodium alginate (NaAlg) were used as ionic crosslinkers. Dynamic swelling of noncrosslinked (Ch) as well as singly (Ch/TPP, Ch/NaAlg) and doubly (Ch/N…
Nanotechnology is a field of applied science focused on the design, synthesis, characterization and application of materials and devices on the nanoscale. The application of nanotechnology within medicine has the ability to revolutionize the cure, alleviation and prevention of disease drastically, and ultimately reinf…
2 Abstract: This paper presents the thermal comfort properties of single jersey knitted fabric structures made from cotton, regenerated bamboo and cotton-bamboo blended yarns. Cotton, bamboo fibre and blends of the two fibres (100% cotton, 100% bamboo, 50:50 cotton: bamboo, 67:33 cotton: bamboo, 33:67 cotton: bamboo)…
Nanoparticles of iron oxide generated by wearing of vehicles have been modelled with a tailored solution of size-uniform engineered magnetite particles produced by the Bradley reaction, a solvothermal metal-organic approach rendering hydrophilic particles. The latter does not bear any pronounced surface charge in anal…
Multiscale molecular modelling (MsM) techniques are applied in many fields of material science, but it is particularly important in the polymer field, due to the wide range of phenomena occurring at different scales which influence the ultimate properties of the materials. In this context, MsM plays a crucial role in…
Biologically triggered exploding microcapsules were synthesized by layer-by-layer assembly of biopolymers. The microcapsules showed controlled rupturing behaviour upon exposure to a pathologically relevant biomolecule, trypsin. These microcapsules offer significant potential for clinical applications.
Facial off-axis sputtering was used to crystallize in situ-grown ITO films onto a polyethylene terephthalate (PET) substrate at 120°C. The process caused no mechanical damage to the substrate. The 100-nm-thick crystalline ITO films showed a resistivity of about 4.2 × 10 −4 Ω-cm and a transmittance of about 83% at a wa…
A series of metalloporphyrin dimers were modularly prepared and shown to catalyze the methanolysis of a phosphate triester, yielding rates that are large compared to the rate of the uncatalyzed reaction. Up to 1300-fold rate acceleration can be achieved via a combination of cavity-localized Lewis-acid activation and m…
Split ring resonator (SRR) structure can potentially be incorporated onto the truncated pyramidal microwave absorber.This study considers three different patterns of edge couple split ring resonator (EC-SRR) designs.Each EC-SRR design is then placed onto the truncated pyramidal microwave absorber.Outer split gap dimen…
Four new lead(II) or bismuth(III) selenites and a tellurite, namely, Pb(3)(TeO(3))Cl(4), Pb(3)(SeO(3))(2)Br(2), Pb(2)Cd(3)(SeO(3))(4)I(2)(H(2)O), Pb(2)Ge(SeO(3))(4) and BiFe(SeO(3))(3), have been prepared and structurally characterized by single crystal X-ray diffraction (XRD) analyses. These compounds exhibit five di…
Combining copper(II) chloride, 4-(1H-pyrazol-3-yl)pyridine and triethylamine in dimethylformamide (DMF) results in the instantaneous formation of a metallogel with as little as 0.51 wt% of gelator. The metallogel was found to encapsulate a luminescent lanthanide cluster, yielding a luminescent metallogel.
Hydrothermal synthesis of [Cr(III)(2)(OH)(4)Nb(10)O(30)](8-) in gram-scale quantities leads to a new polyoxometalate ion composed of two CrNb(6)O(19) Lindqvist-type units that are fused via shared faces. The two Cr(III) atoms are located in the centre of the molecule and are bridged by two μ(4)-O atoms. Electronic tra…
Gold nanochains were prepared at the air/water interface under the Langmuir monolayer of a long-chain ionic liquid 1-hexadecyl-3-methylimidazolium bromide (C16mimBr) through the reduction of AuCl4− ions by UV-light irradiation. It is revealed that these nanochains are self-assembled from gold nanoparticles about an av…
Developments in specific DNA detection assays have been shown to be increasingly beneficial for molecular diagnostics and biological research. Many approaches use optical spectroscopy as an assay detection method and, owing to the sensitivity and molecular specificity offered, surface enhanced Raman scattering (SERS)…
The simultaneous improvement of the melting temperature (T(m) = 224 °C) and the decomposition temperature (T(10) = 359 °C) of poly(lactide)s was achieved by the stereocomplex formation of poly(l-lactide) and poly(d-lactide) with bio-based aromatic groups at both initiating and terminating chain ends.
The heptadentate Schiff base ligand, 2-(2-hydroxyphenyl)-1,3-bis[4-(2-hydroxyphenyl)-3-azabut-3-enyl]-1,3-imidazoline (H(3)api), yields [Ln(2)api(2)] species when combined with lanthanide salts under basic conditions. A survey of the magnetic properties of this dinuclear lanthanide motif (Ln = Gd, Tb, Dy, Ho) has iden…
Molecule-sized fluorescent emitters are much sought-after to probe biomolecules in living cells. We demonstrate here by time-dependent density functional calculations that the experimentally achievable 1-2 nm sized silicon carbide nanocrystals can emit light in the near-infrared region after introducing appropriate co…
For applications in luminescent solar concentrators harvesting subgap photons, either via direct irradiation of solar cells with optimized band gap or via sensitization of an up-conversion process, exact knowledge and tunability of both the spectral shape and the intensity of the emission are of paramount importance.…
The diacetalized diol 2,4:3,5-di-O-methylene-D-glucitol (Glux), a bicyclic compound derived from D-glucose, was used as a comonomer of 1,6-hexanediol in polycondensation in the melt with dimethyl terephthalate to produce a set of aromatic copolyesters (PHxGluxyT) with Glux contents ranging from 5 to 32%-mole. These su…
