We highlight the significance of capillary pressure in the directed assembly of nanorods in ordered arrays of colloidal particles. Specifically, we discuss mechanisms for the assembly of carbon nanotubes at the interstitial sites between latex polymer particles during composite film formation. Our study points to gene…
Electronic structures of five- and six-coordinate iron(III) corrolazine complexes are determined by means of 1 H NMR, 13 C NMR, EPR, and Mössbauer spectroscopy as well as SQUID magnetometry. A series of five-coordinate complexes, [Fe III (TBP 8 Cz)(L)]* where the axial ligands(L) are cyanide(CN - ), imidazole(HIm), 1-…
In this work, we suggest a method for microplasma synthesis of multicomponent iron-containing oxide coatings on the surface of aluminum alloys. For producing the coatings, we use a homogeneous electrolyte that contains iron in the form of its complexes with EDTA 4− and has a pH value of 9–10. The dynamics of the decre…
The outcome of protein crystallization attempts is often uncertain due to inherent features of the protein or to the crystallization process that are not fully under control of the experimentalist. The aim of this contribution is to propose user-friendly tools that can increase the success rate of a protein crytalliza…
Surfactant-mediated polyaniline (PANI) samples were fabricated using an electrodeposition technique for electrochemical supercapacitor applications. We investigated the effect of surfactants such as sodium dodecyl sulfate (SDS), polyvinyl alcohol (PVA), ethylenediaminetetraacetic acid (EDTA) on the PANI morphologies.…
The shape control inside a trenched 4H-SiC by atmospheric-pressure chlorine (Cl 2 ) etching has been investigated. The trench fabricated by a plasma process on the 4H-SiC(000 ) C-face with 4°-off toward [11 0] was used. The inside of the 4H-SiC trench was thermally etched in Cl 2 ambience at 900 °C. The subtrenches in…
In this pilot scale study, we examined the effects of alkaline extraction time on xylan removal, pulp and paper properties, and the consequences that need to be addressed when scaling up and intensifying the process. Alkaline extraction of bleached birch kraft pulp yields two fractions: pure polymeric xylan and pulp w…
This study is focused on the modification of wood fiber by using a reactive diisocyanate (toluene diisocyanate, TDI) linker to couple wood fiber with cetyl alcohol and the investigation of its effects on mechanical properties of wood fiber–HDPE composites. The reaction of TDI with wood fiber and then cetyl alcohol res…
Ferromagnetic resonance has been investigated in Ni2MnSn Heusler alloy lms. The lms were deposited at 673 < T < 723 K on MgO(001) substrates by means of magnetron sputtering. X-ray diraction conrmed that the lms were epitaxial. The lms had magnetic parameters typical of bulk Ni2MnSn with L21 structural order.
The aerated bioreactor is a promising technology for wastewater treatment. Activated carbon fiber (ACF) used as a biomembrane carrier in wastewater disposal has attracted much more concern recently. The high modulus polyacrylonitrile (PAN)-based ACF was successfully used as a biomembrane carrier for hard-to-biodegrade…
We describe the optical and structural characterization of highly luminescent thioglycolic acid–stabilized CdTe quantum dots (CdTe-QD) synthesized in water. Samples prepared under different reflux times were characterized using transmission electron microscopy (TEM), X-ray diffraction, Raman spectroscopy, absorbance a…
Abstract In this investigation, a chiral poly) ester‐imide) (PEI) via direct polyesterification of N,N ′‐(pyromellitoyl)‐bis‐( L ‐tyrosine dimethyl ester) and N ‐trimellitylimido‐ L ‐methionine was prepared using the tosyl chloride/pyridine/ N,N ′‐dimethylformamide system as a condensing agent. This approach allows th…
The rate of degradation of carbon nanotubes (CNT) comprising a field emission cathode is calculated. The sputtering of CNT material by incident ions formed through the electron impact ionization of the residual gas molecules is considered as the degradation mechanism. The degradation rate and the relevant lifetime of…
We report a novel surface enhanced Raman Scattering (SERS) substrate platform based on a common filter paper adsorbed with plasmonic nanostructures. Paper based SERS substrate overcomes many of the challenges associated with conventional SERS substrates based on rigid substrates such as silicon and glass. The paper-ba…
A metal nanoparticle core can be formed in two different ways: by sequential and by parallel growth. Sequential growth is achieved by elemental reaction M n + M = M n + 1, whereas parallel growth is achieved by M x + M y = M x + y . If the process of the core growth is random, then the particle size distribution is Ga…
The spectral and coherent properties of nitrogen-vacancy (NV) centers in diamond are described, together with the techniques used for their experimental investigation. Particular attention is given to recently developed methods of initialization and spin-state identification for a single NV center or a spin system bas…
A 3D computer modeling and simulation has been used to predict crystallization kinetics and crystal morphology in polymers under the non-isothermal condition. A parametric study is used to explore the influences of thermal conditions on the crystallization. The results indicate that cooling rate has a strong impact on…
In this paper, we present the design and development of a magnetic resonance imaging (MRI)-compatible tendon-driven robot to overcome the limitations of our previous minimally invasive neurosurgical intracranaial robot (MINIR). In this prototype, the robot is made of plastic and the MRI-compatible shape memory alloy (…
Polycrystalline samples of degenerate n-type KxBa8−xZnyGe46−y (y∼8-x/2) with the type-I clathrate structure (No. 223, Pm3¯n) were prepared by powder metallurgy to obtain a high-efficiency Ge-based clathrate. Their Zn atoms preferred to exist at the 6c site in the framework, and consequently, the samples with x around…
Citrate-nitrate method was used to synthesize (Fe,Co)/MgO-Al 2 O 3 , (Fe,Mo)/MgO-Al 2 O 3 , and (CoMo)/MgO-Al 2 O 3 catalysts for production of carbon nanotubes. Multi-walled nanotubes were formed on these catalysts by catalytic pyrolysis of a propane-butane mixture.
