Purpose In order to characterize the temperature regulating ability of fabrics containing phase change material (PCM), the test instrument has been designed and built. Design/methodology/approach To assess temperature regulating ability, temperature regulating factor (TRF) is determined. TRF is defined by Hittle as a…
Appropriate addition of CuO/V2O5 and the reduction of the granularity of the raw materials particle decrease the sintering temperature of NiZn ferrite from 1200 degrees C to 930 degrees C. Furthermore, the magnetic properties of the NiZn ferrite prepared at low temperature of 930 degrees C is superior to that of the N…
We perform a study of the interfacial properties of a model suspension of hard sphere colloids with diameter ${\ensuremath{\sigma}}_{c}$ and nonadsorbing ideal polymer coils with diameter ${\ensuremath{\sigma}}_{p}$. For the mixture in contact with a planar hard wall, we obtain from simulations the wall-fluid interfac…
Abstract The surface modification of nano calcium carbonate (nCaCO 3 ) particles was carried out with a soluble compound of lanthanum via a coating process of chemical deposition, and nCaCO 3 particles covered with a compound of lanthanum (nCaCO 3 La) were prepared. The polypropylene (PP)/nCaCO 3 and PP/nCaCO 3 La c…
Abstract The effects of corn starch (CS) filler and lysine diisocyanate (LDI) as a coupling agent on the crystallization behavior of a poly(butylene succinate) (PBS)/CS ecocomposite were investigated using differential scanning calorimetry. In isothermal crystallization, n values for pure PBS were from 2.33 to 2.82. O…
Abstract The improvement of the oxygen‐barrier properties of poly(ethylene terephthalate) (PET) via blending with an aromatic polyamide [poly( m ‐xylylene adipamide) (MXD6)] was studied. The compatibilization of the blends was attempted through the incorporation of small amounts of sodium 5‐sulfoisophthalate (SIPE) in…
Abstract The binary lanthanide catalyst for 1,3‐butadiene was invented for 40 years ago. However, it has not been employed in commercial application due to its poor solubility and low activity. Nanosized neodymium chloride (NdCl 3 ) was prepared in tetrahydrofuran (THF) medium through dissolution, chelation, and collo…
Abstract Soluble polypyrrole (PPy) samples advanced in electrical conductivity σ were chemically synthesized with dodecylbenzenesulfonate (DBS) sodium salt as a dopant, with poly(ethylene glycol) (PEG) as an additive, and with ammonium persulfate as an oxidant. The PPy–DBS–PEG samples were soluble in organic solvents…
Purpose To establish new measurement technologies in textiles and clothing. Design/methodology/approach Three areas are covered, diverse in methodology and approach: measurement of fabric mechanics, measurement of seam quality, and measurement of human size and shape. Findings Three new measurement technologies have b…
The structural dependence of the magnetic, transport, optical, and magneto-optical (MO) properties of Cu2MnAl Heusler alloy (HA) thin-film samples was investigated. Disordered thin films of Cu2MnAl HA fabricated by vapor-quenching deposition onto substrates cooled by liquid nitrogen behave as highly resistive Pauli pa…
The element-specific valence- and conduction-band densities of states for the high-dielectric-material $\mathrm{Ca}{\mathrm{Cu}}_{3}{\mathrm{Ti}}_{4}{\mathrm{O}}_{12}$ have been measured using soft x-ray emission and absorption spectroscopies. Ti ${L}_{\ensuremath{\alpha},\ensuremath{\beta}}$, Cu ${L}_{\ensuremath{\al…
Abstract Summary: We succeeded in the synthesis of azo side chain containing polysiloxanes with broad smectic C* and A phases. In these polymers the phase transition temperatures can be shifted reversibly by up to 17 °C by irradiation with UV ( cis ) or VIS ( trans ) light. Thin films of these polymers in the smectic…
Porous low-dielectric constant (low-κ) SiCOH thin films deposited using a plasma-enhanced chemical-vapor deposition have been comprehensively characterized before and after exposure to a reactive-ion-etch-type plasma of N2 and H2 chemistry. The low-κ film studied in this work is a carbon-doped silicon oxide film with…
In situ observation of the transformation of diamond nanoparticles (DNP) into onion-like carbon (OLC) was made during electron-beam irradiation inside an ultrahigh-vacuum transmission electron microscope at 300 kV with 8.5×1023e∕m2. 5 nm DNP changed into OLC within about 10 min of irradiation, while 20 nm DNP did not…
Abstract Rice husk was used as filler in the production of rice husk (RH)–polyester composites and was subjected to three types of chemical modification. The chemical reagents employed in this study were glycidyl methacrylate (GMA), maleic anhydride (MAH), and succinic anhydride (SAH). This study revealed that the che…
Purpose To investigate the inhibiting effect of the cationic surfactant cetyl trimethylammonium chloride (CTAC) on aluminum (Al). Design/methodology/approach Pure aluminum rods were immersed in hydrochloric acid (HCl) and sodium hydroxide (NaOH) solutions for weight‐loss tests and potentiostatic polarization measureme…
Purpose In this paper, special attention is focused on the study of the relaxation phenomena of fabrics containing elastane yarn. Design/methodology/approach For this purpose, the relaxation phenomena of wound fabric under constant deformation, as the consequence of accumulated stress during winding, were analysed. Ma…
Assembly of transmembrane (TM) domains is a critical step in the function of membrane proteins, and therefore, determining the amino acid motifs that mediate this process is important. Studies along this line have shown that the GXXXG motif is involved in TM assembly. In this study we characterized the minimal dimeriz…
Abstract Summary: Three kinds of organoclay, i.e., Cloisite15A® (C15A), Cloisite20A® (C20A), and Cloisite30B® (C30B) were modified with silane to prepare twice functionalized organoclay (TFC). The pristine Cloisite® clays and the TFC were melt compounded with poly( L ‐lactide) (PLLA) and morphology of the composites w…
A chamberless, remote plasma deposition process has been used to coat silicon and plastic substrates with glass at ambient conditions. The films were deposited by introducing an organosilane precursor into the afterglow of an atmospheric plasma fed with helium and 2 vol% oxygen. The precursors examined were hexamethyl…
