To meet the future emission legislations, selective catalytic reduction aftertreatment system becomes a leading aftertreatment technique for heavy-duty diesel engines. In this article, a two-cell selective catalytic reduction model is first calibrated and verified on an experimental test bench. In order to regulate th…
In order to elucidate the magnetic nature of K 2 NiF 4 -type 3 d transition metal oxides, we have measured μ + SR spectra for Sr 2 VO 4 , LaSrVO 4 , and Sr 2 CrO 4 using powder samples. ZF- and wTF- μ + SR measurements propose that Sr 2 VO 4 enters into the static antiferromagnetic (AF) order phase below 8 K. In addit…
The global minimum structures of AlB3H2n (n = 0-6) clusters are determined using the stochastic search method at the B3LYP/6-31G level of theory. These initially specified geometries are recalculated using B3LYP and CCSD(T) methods using the 6-311++G(**) basis set. The structural and electronic properties of the two l…
Hereby, we present synthesis and mesomorphic properties of bent-shaped liquid crystals with 3-hydroxybenzoic acid central core. The mesomorphic properties were tuned by lateral substitution in the position 4 of the central unit and by the length of the terminal alkyl chains. For comparison, materials based on 4-fluoro…
Wide-bandgap hexagonal boron nitride (h-BN) nanosheets, white graphene, can be uniformly grown on conducting Cu foils with high quality. Here, we show that h-BN monolayers on Cu substrates exhibit ferromagnetic, antiferromagnetic, or ferrimagnetic properties with ozone (O 3 ) molecules or oxygen–hydrogen (O–H 2 ) grou…
Poly(L-lactic acid) (PLLA) is a biodegradable plastic and one of the most famous plastics made from biobased materials. However, its physical strength is insufficient compared to general-purpose plastics. In this study, the effect of methylcyclodextrin (MeCD) addition on the structure and physical properties, especial…
Composite natural rubber foams were successfully prepared from the vulcanization of natural rubber in a sulfur curing system. The natural rubber matrix phase was added with chlorinated polyethylene, kaolinite, and alumina. The morphology of natural rubber composite foams was altered when a gas was generated at the vul…
ABSTRACT Three main chain thermotropic liquid crystalline (LC) azobenzene polymers were synthesized using the azobenzene twin molecule (P4P) having the structure Phenylazobenzene‐tetraethyleneglycol‐Phenylazobenzene as the AA monomer and diols like diethylene glycol, tetraethylene glycol (TEG), and hexaethylene glycol…
Blends of polypropylene (PP) and polyamide 6 (PA6) with multiwalled carbon nanotubes (MWNTs) were prepared using different processing strategies in a twin-screw micro-compounder. The effect of MWNTs on the crystallization behaviour of the PP phase and the PA6 phase of the blend has been investigated through non-isothe…
A complex cyclic TiO 2 -NTs porosity trend throughout anodization was found, due to the microscopic mechanisms behind the nanotubes' formation and growth.
The present work deals with the synthesis of nanostructured Co–MgO mixed oxides with different weight ratios of cobalt by a facile co-precipitation method as a catalyst for low-temperature CO oxidation. The prepared samples were characterized by X-ray diffraction (XRD), N2 adsorption/desorption (BET), Fourier transfor…
Graphite samples exposed to H, D and He plasma at fluencies from 1016 to 1018 cm−2 have been investigated by means of atomic force and Raman microscopies. The ion energy was varied between 40 and 800 eV, and the ion incidence was either perpendicular (Highly Oriented Pyrolitic Graphite) or parallel (carbon/carbon comp…
Hydrothermally stable ES40-derived silica matrices with less than 30% pore volume loss are closely associated with a more open silica microstructure formed from thermal consolidation of larger silica particles.
Abstract The synthesis, solution behavior and photophysical properties of several heteronuclear bimetallic d/f complexes that utilise a RuII bis‐terpyridine moiety as the sensitiser for EuIII, NdIII and YbIII luminescence are reported and compared to a GdIII analogue. The former compounds display sensitised emission i…
There are several studies regarding polyacrylonitrile composite nanofibers with polyaniline doped with dodecylbenzene sulfonic acid and solved by N,N′-dimethyl formamide which were mostly performed to analyze the thermal and morphological properties. In this study, camphor sulfonic acid-doped polyaniline and polyacryl…
In this study, lithium disilicate ( LS 2 ) glass samples with different particle sizes ranging from less than 105 to 850 μm were prepared. These specimens were inserted in a Pt‐Rh DSC crucible and heated to 850°C at different rates (ϕ = 0.5–30 K/min) to identify their crystallization peaks. The activation energies for…
The present work introduces the easy modification of the water-in-oil microemulsion procedure aimed at the doping of the Tb(III) complexes within core or shell zones of the silica nanoparticles (SNs), which are designated as "core-shell", "shell", and "core". The dye molecules, chelating ligands, and copper ions were…
In this work, a 500 nm thick MgO layer deposited on the physically evaporated amorphous InSe thin film substrate is designed as a window for the MgO/InSe terahertz resonators. The optical properties including the reflectance and the dielectric constant dependence on the angle of incidence (θi), the normal transmittanc…
We present our results of a local probe study on EuFe$_{2}$(As$_{1-x}$P$_{x}$)$_{2}$ single crystals with $x$=0.13, 0.19 and 0.28 by means of muon spin rotation and ${}^{57}$Fe M\"ossbauer spectroscopy. We focus our discussion on the sample with $x$=0.19 viz. at the optimal substitution level, where bulk superconducti…
The aim of this research was to align functionalized multiwalled carbon nanotubes (MWCNT)–valine amino acid into a chitosan matrix. At first, the MWCNTs were functionalized with valine amino acid and chitosan/grafted MWCNT-valine composites were prepared via covalently bonding of chitosan on the surface of MWCNT-valin…
