Multi-purpose amphiphilic branched copolymer surfactants can be used to simultaneously stabilise and cross-link emulsion droplets to produce encapsulated spheres and hollow capsules.
The thermal diffusivities of AlN thin films with a thickness of about 600 nm deposited by reactive rf magnetron sputtering were measured by the pulsed light heating thermoreflectance technique. The AlN films contain oxygen impurities ranging from 1.1 to 13.6 at. % depending on the sputtering conditions. The measured t…
The persistent photoinduced magnetization (PPM) in the low bandwidth material Pr(1-x)Ca(x)MnO₃ at the low hole doping level of x = 0.1 is reported. Upon zero-field cooling under photoexcitation, significant improvement of the ferromagnetic (FM) ordering was observed in the low temperature spin-glass phase. However, up…
With the aid of the turbidity-spectrum method, the cloud-point method, X-ray analysis, and polarization microscopy and the use of a polarization-photoelectric apparatus, the sizes of supramolecular particles are determined and the liquid-crystalline phase transitions and the structure of cellulose ether solutions are…
Thermophysical properties of high temperature melts are important to better understand material processes such as casting, welding, and crystal growth. Containerless processing techniques combined with non-contact diagnostic methods play significant roles in thermophysical property measurements of high temperature mel…
Nanofibre mats of poly(vinyl alcohol) (PVA), waterborne polyurethane (WBPU) and nanometre silver (Ag) colloids have been fabricated by an electrospinning method in aqueous solutions. Since PVA is a water soluble and biocompatible polymer, it is one of the best materials for preparation of electrospun antibacterial nan…
The synthesis and the catalytic activity of bis(μ-chloro)-bridged, phosphapalladacycle-fused diporphyrins (M-porphyrin-appended phosphapalladacycles: M = Zn , Ni , free-base), as well as the coordinating ability of their precursors, meso-phosphanylporphyrins are reported. Treatment of meso-phosphanylporphyrinatozinc(I…
A series of 1,3-dichloro-2-propanol-blocked diisocyanates, based on diisocyanates including 4,4′-methylene di(phenyl isocyanate), toluene-2,4-diisocyanate, isophorone diisocyanate and 1,6-diisocyanatohexane, were prepared and characterized thoroughly by Fourier transform infrared, 1 H-NMR, 13 C-NMR spectroscopic metho…
The method of oxygen isotopic exchange was used to study the oxygen exchange kinetics and diffusion in the LaMnO 3 + δ oxide at the temperatures of 600–850°C and in the range of oxygen pressures of 133.3–9332.4 Pa. The rate of interface exchange and diffusion coefficient of oxygen are much lower in the case of LaMnO 3…
The effect of the austenitizing temperature on the transformation of the primary structure of a tungsten-molybdenum high-speed steel of the R6M5 type modified by an addition of a titanium boride powder has been studied. The results of metallographic, X-ray diffraction, and electron-microprobe analysis of the steel hav…
In this paper, we describe the synthesis and characterization of a luminomagnetic microspheres with core-shell structures (denoted as Fe3O4@ SiO2 @SiO2-Tb(PABA)3). The luminomagnetic microspheres were characterized by field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), Fourier…
Interpenetrating polymer network (IPN) based drug delivery system is basically designed to deliver drugs at a predetermined rate for a desired period of time with minimum fluctuation. Due to its physical and biological characteristics such as enhanced solubility of hydrophobic drugs, excellent swelling capacity, impar…
Dichroic dyes, based on anthraquinone chromophores, for incorporation into various liquid-crystalline host mixtures have been prepared. For each dye, which has been designed to absorb at different regions of the visible spectrum, we investigate liquid crystalline behaviour and prepare mixtures of dyes that also promot…
Extensive research efforts have been devoted to nanowires because of their novel electronic, optical and thermoelectric properties due to spatial confinement in two dimensions. Among various fields, nanowires have been of interest in the thermoelectric community not only for their novel thermoelectric properties but a…
The amide proton exchange rates in various lanthanide(III) DOTA-tetraamide complexes were investigated by CEST as a function of variable chemical structures and charges on the amide substituents. Comparisons were made between YbDOTA-(gly)(4)(-) (Yb-1), YbDOTA-(NHCH(2)PO(3))(4 (5-) (Yb-2) and YbDOTA-(NHCH(2)PO(3)Et(2))…
Corrosion Inhibition of the mild steel in 1M HCl N-phenylhydrazine-12-dithiocarboamide (PDA) has been investigated using weight-loss, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. Inhibition efficiency increases with increase in inhibitor concentration, and solution temperat…
One-dimensional (1D) nanostructured polyindole (Nano-Pind) was synthesized with 10 minutes (Pind-10 m) and 24 hours (Pind-24 h) of polymerization time using a facile chemical oxidative polymerization method. The obtained Nano-Pinds were explored to study the differences in their structural, optical, spectral and condu…
Tensile properties and impact damage tolerance of hemp fiber and chopped strand mat (CSM) glass fiber composites have been evaluated and compared. The absolute and specific tensile properties of CSM glass fiber composites were found to be much superior to hemp fiber composites. Impact damage tolerance of hemp fiber co…
Supercritical CO 2 (scCO 2 ) is used as a medium for foaming amorphous polymers. Astudy of the solubility of supercritical CO 2 in several amorphous polymers (PS andPMMA) and blends is performed, followed by an investigation of the foaming behavior of the polymer–gas systems. Nano-structuring triblock copolymers (styr…
