The removal of acetic acid and glycolic acid from aqueous solution by the weakly basic adsorbent Amberlite IRA-67 has been studied at three different temperatures. Amberlite IRA-67 removed both acids very well from aqueous solution. The maximum adsorption efficiency has been found to be 86.29 % and 61.36 % for glycoli…
Nanoporous anodic aluminum oxide (AAO) has been used widely as a template for device fabrication. In many nanostructured electro-optical device designs, AAO grown on an ITO substrate is the desired configuration. However, a residual thin aluminum oxide barrier layer between ITO and the AAO pores remains and process no…
The samples of porous InP were grown up by a method of anode etching on a substrate (100) InP n-type. The samples were characterized by SEM and photoluminescence (PL) where a blue shift was observed in PL. To remove surface oxides from the surface of porous InP using the thermal cleaning of the samples in a stream of…
The unusual properties of many multifunctional materials originate from a structural phase transformation and consequent martensitic microstructure. Phase-field models are typically used to predict the formation of microstructural patterns and subsequent evolution under applied loads. However, formulating a phase-fiel…
Abstract Mit ihrer einzigartigen sequenzspezifischen Selbstorganisation und der Fähigkeit zur Substraterkennung spielen Peptide in natürlichen Systemen eine entscheidende Rolle bei der Steuerung der Biomineralisation anorganischer Nanostrukturen und der Entstehung von Weichgewebe. Daher sind Peptide auch besonders wer…
Abstract A novel method of creating planar aligned columnar discotic liquid crystals (cDLCs) on surfaces, which also gives control over the azimuthal angle, is presented. Surfaces are chemically patterned with stripes via microcontact printing of organothiol self‐assembled monolayers (SAMs) on gold, or via deep UV pat…
The photoluminescence (PL) response of highly porous CdSe aerogels to triethylamine (TEA) is investigated and compared to results from prior studies on single crystals and nanoparticle-polymer composites. As-prepared CdSe aerogels show significant and reversible enhancement of luminescence intensity upon exposure to T…
Abstract Exfoliated nanocomposites of polyamide 6 (PA6) with residual monomer and an organically treated montmorillonite (3 and 5 wt %) were produced by twin‐screw extrusion. The composites had their steady state, dynamic, and transient rheological properties measured by parallel‐plates rheometry; their exfoliation le…
Three-dimensional bulk metamaterials that operate in the terahertz (THz) frequency range were fabricated by stacking 100 two-dimensional sheets containing metallic split-ring resonators (SRR) on thin polyethylene terephthalate film substrates. The THz magnetic resonance for the incident magnetic field perpendicular to…
White light emitting semiconductor nanocrystals (NCs) have been successfully synthesized from 8-hydroxyquinoline-5-sulfonic acid (HQS) decorated manganese doped ZnS NCs through fine tuning the surface-coordination emission and dopant emission of the NC host. The HQS functionalized manganese doped ZnS NCs (QS-ZnS:Mn),…
Carbon nanomaterials have advanced rapidly over the last two decades and are among the most promising materials that have already changed and will keep on changing human life. Development of synthetic methodologies for these materials, therefore, has been one of the most important subjects of carbon nanoscience and na…
Transmission synchrotron diffraction was employed to characterize the Ga ordering in magnetostrictive ${\text{Fe}}_{100\ensuremath{-}x}{\text{Ga}}_{x}$ alloys with Ga concentrations from 0 to $20.3\text{ }\text{at}\text{.}\text{ }\mathrm{%}$. The experiments focused on the development of atomic short-range ordering (S…
Combining neutron diffraction, neutron spin echo, differential scanning calorimetry, and dielectric spectroscopy, we have investigated the structure and dynamics of poly( n -butyl methacrylate) (PBMA) and poly( n -hexyl methacrylate) (PHMA). Signatures of the occurrence of a glass transition associated with the freezi…
Abstract A systematic research has been conducted to investigate the matrix properties by introducing nanosize TiO 2 (5 nm, 2.0–30% by weight) filler into a poly (methyl methacrylate) (PMMA) resin. A twin screw extraction process was developed to disperse the particles into the PMMA. The thermal, mechanical, and visco…
Pollution flashover of line insulators may cause regional accidents. Research on the effect of non-uniform pollution on the electrical performance of insulators is important for the outdoor insulation coordination. A study on the effect of the non-uniform pollution distribution on the withstand characteristics of an i…
Structural properties of NaAlH 4 /C nanocomposites were studied using 23 Na and 27 Al solid-state NMR. The samples were synthesized by melt infiltration of a highly porous carbon support, with typical pore sizes of 2−3 nm. Physical mixtures of high surface carbon with alanates in different stages of hydrogen desorptio…
Powder x-ray diffraction study of Mn2NiGa ferromagnetic shape memory alloy shows the existence of a 7M monoclinic modulated structure at room temperature (RT). The structure of Mn2NiGa is found to be highly dependent on residual stress. For higher stress, the structure is tetragonal at RT, and for intermediate stress…
Abstract Nanocomposite films and coatings with improved properties were produced from ultrasonic dispersed chitosan and hydrophilic bentonite nanoclay. Bio‐hybrid coatings were applied onto argon–plasma‐activated LDPE coated paper. The intercalation of chitosan in the silicate layers was confirmed by the decrease of d…
We theoretically studied how the electric field effect can modify thermoelectric properties of intrinsic, $\mathbit{n}$-type and $\mathbit{p}$-type bismuth telluride nanowires with the growth direction [110]. The electronic structure and the wave functions were calculated by solving self-consistently the system of the…
Synthesis and characterization of gold-nanoparticle-cored dendrimers (NCDs), in which the dendrons are attached to the gold core through gold-carbon bonds, are described. Synthesis of these materials involved the simultaneous reduction of HAuCl(4) and a Fréchet-type dendron with a diazonium group at the focal point, a…
