Hemp fibre is a renewable resource that has the market potential for producing new fibrebasedproducts as well as replacing existing ones. Decortication onstitutes a key step in the production of high-quality hempfibres. A hemp decortication experiment was conducted using a. lab-scale planetary ball mill. Varying treat…
Abstract Monodisperse magnetic polystyrene (PS) microspheres were prepared in the presence of PS seed particles and styrene‐based magnetic colloid by the method of magnetic colloid swelling polymerization. The PS seed particles were prepared in advance by soap‐free emulsion polymerization. Styrene‐based magnetic collo…
Abstract This paper reports on the effect of the temperature used to activate kaolinite‐based paper industry waste on the hydration products obtained when the activated waste was mixed with a lime solution. After activation at temperatures ranging from 500° to 700°C, clay waste exhibited high pozzolanic activity. Anal…
This study was conducted to evaluate the bioavailability of phenanthrene adsorbed onto nano-ZnO by comparing its toxicity to Daphnia magna exposed to nano-ZnO only for 24 and 48 h. The LC50 values of phenanthrene-loaded and phenanthrene-free nano-ZnO were determined. SPSS software, independent-samples t-test technique…
Abstract The composite double‐layered films, for the packaging application of postharvest fruits and vegetables, were prepared by laminating low‐density polyethylene (LDPE) and poly[styrene‐ b ‐(ethylene‐ co ‐butylene)‐ b ‐styrene] (SEBS) modified with zeolite ZSM‐5. The film was characterized by scanning electron mic…
Abstract We succeeded in the first direct intercalation of an organic compound into carbonate layered double hydroxide (LDH) by using alcohol as the solvent at 50 °C. Furthermore, carbonate ion in carbonate LDH was easily exchanged with chloride or nitrate ion in methanol.
X-ray emission spectroscopy and resonant inverse photoelectron spectroscopy (RIPES) have been used to investigate the photon emission associated with the Ce 3${d}_{5/2}$ and Ce 3${d}_{3/2}$ thresholds. Strong resonant behavior has been observed in the RIPES of a Ce oxide near the 5/2 and 3/2 edges.
The rolling texture of Body Centered Cubic (BCC) low carbon and interstitial free (IF) steel consists of two crystallographic fibers, the α fiber (⟨110⟩ //RD) and the γ fiber (⟨111⟩ //ND). Cells, subgrains, and microbands, where these are not associated with significant lattice curvature, provide the driving forces fo…
Substitution of more than $33%$ of the naturally abundant $^{16}\mathrm{O}$ in strontium titanate ${\mathrm{SrTiO}}_{3}$ by $^{18}\mathrm{O}$ causes the system to become ferroelectric at low temperatures. The ferroelectricity has been observed via susceptibility measurements, but to date the details of the ferroelectr…
Polyanilines, well-known conductive polymers, serve as a redox mediator for catalysis in organic redox reactions. This account describes the synthesis and application of hybrid catalysts consisting of polyanilines and transition metals or metal nanoparticles.
Abstract The synthesis of novel polyimide (PI) films containing chirals in side chain was investigated for utilizing in twist nematic (TN) liquid crystal display (LCD). The polyimide with amine side groups (PI4 a.m.) was prepared by two steps copolymerization of 4,4′‐hexafluoroisopropylidene diphthalic anhydride (6FDA…
Abstract A single phase of Ca4Bi6O13 crystal was obtained at lower calcination temperature in a citric acid complex method than in a solid-state reaction. From the diffuse reflection spectra, it was found that Ca4Bi6O13 is direct-gap material and that the optical band gap is 2.92 eV. After heating at 600 °C or above,…
Abstract Multiwalled carbon nanotube (MWCNT)‐filled polycarbonate (PC)/styrene–acrylonitrile (SAN) blends with a wide range of blend compositions were prepared by melt mixing in a rotational rheometer, and the effect of SAN on the electrical properties of the PC/MWCNT composites was studied. The structure/electrical p…
Abstract Polyamide 6/montmorillonite (MMT) nanocomposites were prepared by melt compounding method comprising 1–7.5 wt % of Nanomer I.24 TL or 5 and 10 wt % of Cloisite 15A organically modified nanoclays. The composite samples were characterized by synchrotron X‐ray, thermal and FT‐IR spectroscopy methods looking for…
Abstract The time‐domain nonlinear spectroscopy of a single silver nano‐object is investigated by combining the spatial modulation linear spectroscopy technique with a high‐sensitivity femtosecond pump–probe setup. The investigated single nanoparticle is first optically characterized for size and shape via quantitativ…
Excitonic absorption of semiconducting carbon nanotubes for polarization perpendicular to the tube axis is theoretically studied in an effective-mass approximation including higher-order terms describing trigonal warping, curvature, lattice distortion, and electron-hole asymmetry. Asymmetry between electrons and holes…
Atom-probe tomography analyses of a nominally 6.25% Cr-doped In2O3 thin film, prepared by ceramic synthesis e-beam evaporation, has been performed. It has been shown that there is substantial inhomogeneity of Cr throughout the film (1−8% distribution). The Cr-doped In2O3 film does not display room temperature ferromag…
Abstract A series of linear polyurethane (PU) elastomers containing various amounts (ca. 2–10 wt%) of a diol‐functionalized polyhedral oligomeric silsesquioxane (diolPOSS) were synthesized from organic solvent dispersions. Fourier transform infrared spectroscopy was used to characterize the chemical structure of the d…
Dynamic responses of various types of spin-cycloidal domain walls (DWs) have been investigated for the multiferroic compound DyMnO${}_{3}$ by the dielectric measurements. By exploiting the multiferroic nature of this material, we were able to drive the spin-cycloidal DWs by an electric field and hence elucidate the dy…
We explore the excited state energy landscape of small polyhedral zinc sulfide clusters (Zn(4)S(4) and Zn(6)S(6)) using time-dependent density functional theory and correlated wave function based methods. We predict the optical absorption and photoluminescence spectra of the polyhedral clusters and demonstrate that, u…
