Nanostructured cadmium hydroxide (Cd(OH)2) thin films have been fabricated on glass substrates by the chemical bath deposition method and converted into cadmium oxide (CdO) films by heat treatments. Some of the films were studied as-grown and the others were annealed in air at 150, 300 and 450 °C. The effects of vario…
Abstract Talc and talc modified with trimethoxy(octadecyl)silane (O‐talc) were melt compounded with poly ( L ‐lactide) (PLA). The crystallization behavior, tensile properties, and impact strength of the PLA composites were examined before and after the incorporation of talc and O‐talc. The molecular weight of PLA in t…
Magnetic nanoparticles were the thermoseeds under an alternating magnetic field and can be used to produce highly localized hyperthermia effect on deep-seated tumor. Nevertheless, effective and precisive delivery of nanoparticles to the treatment-intended site remains a challenge. In this study, Fe3O4 nanoparticles we…
Graphene, consisted of a single layer of carbon atom in a two‐dimensional lattice, has superior electrical and physical properties that promise many exciting applications. In this study, graphenes were prepared from graphite powder by chemical method and their images were investigated by TEM and SEM. To develop high p…
BACKGROUND: Serine hydroxymethyltransferase (SHMT), a pyridoxal phosphate-dependent enzyme, plays a vital role in the de novo pyrimidine biosynthesis pathway in malaria parasites. Two genes have been identified in Plasmodium spp. encoding a cytosolic SHMT (cSHMT) and putative mitochondria SHMT (mSHMT), but their roles…
Abstract The influence of diblock copolymer addition on the tack properties of a polyacrylic triblock copolymer/tackifier system was investigated. For this purpose, poly(methyl methacrylate)‐ block ‐poly( n ‐butyl acrylate)‐ block ‐poly(methyl methacrylate) triblock copolymer (MAM) and a 1/1 blend with a diblock copol…
In the present report, we studied the effect of different parameters such as preparation methods, different types of modified clay and matrix flexibility on thermomechanical properties of flexible epoxy/clay nanocomposites. The unmodified clay (cloisite Na + ) was organically modified with decylamines having different…
We report the synthesis of gold nanotubes with variable wall thicknesses that is accomplished by the deposition of sacrificial hydrophobic polymer cores followed by gold shells within an anodic aluminum oxide template. We demonstrate that by varying polymer core hydrophobicity, the resulting gold shell thickness can b…
Abstract In this work, we undertook a comparative study of the dynamic dielectric analysis of two composites: natural‐fiber‐reinforced unsaturated polyester (NFRUP) and E‐glass‐mat‐reinforced unsaturated polyester (EGMRUP). In both composites, two common relaxation processes were identified, the first of which was the…
A novel series of mesotetrakis[aryl]-21H,23H-porphyrin derivatives 2a-j was synthesized from the condensation of aldehyde derivatives 1a-j with pyrrole in the presence of p-toluenesulfonic acid. The synthesized porphyrins were considered as a model to study the free radical-induced damage of biological membranes and t…
The development of a short-wavelength p-n junction device is essentially important for the realization of transparent electronics for next-generation optoelectronics. Nickel oxide (NiO) thin films with a tunable electrical conductivity of both p-type and n-type under the optimized growth conditions using RF sputtering…
Abstract Propylene random copolymer (PPR)/styrene‐ethylene‐butylene‐styrene block copolymer (SEBS)/compatibilizer/organic‐montmorillonite (OMMT) quaternary nanocomposites and PPR/compatibilizer/OMMT ternary nanocomposites were prepared via two‐stage melt blending and influences of compatibilizers, maleic anhydride (MA…
Improvement in the performance of functional nanoscaled devices involves novel materials, more complex structures, and advanced technological processes. The transitions to heavier elements and to thicker layers restrict access to the chemical and physical characterization of the internal material interfaces. Conventio…
In this paper, a polarizability matrix retrieval method for bianisotropic metamaterials is presented. Assuming that scatterers can be modeled by electric and magnetic pointdipoles located at their centers, the induced dipole moments are analytically related to the normally incident fields, while the scattered fields a…
This paper presents the large-signal performance of intrinsically switchable ferroelectric thin-film bulk acoustic resonators (FBARs), as well as their modeling procedure. There has been a growing interest in ferroelectric FBARs due to their electric-field-dependent permittivity and electric-field-induced piezoelectri…
Gefangen: Bei der Selbstassoziation von CdTe-Quantenpunkten (QDs; orange im Bild) in Phosphatpuffer wurden Enzyme (blau) in den CdTe-QD-Hydrogelen verkapselt. Diese QD-Hydrogele mit Enzymen haben sowohl eine Biokatalyse-Einheit als auch eine fluoreszierende Signaleinheit und wurden als multifunktionelle Plattform für…
Spiro-N,N-ketal 5, consisting of a phthaloperine heterocyclic ring and a naphtha[1,8-ef][1,4]diazepine ring, was obtained along with spiro-N,N-ketal 2 via 2,2-condensation in the reaction of ninhydrin with naphthalene-1,8-diamine. Their molecular structures were elucidated by X-ray crystal structural analysis. Aside f…
Colloidal silicon nanocrystal superlattices: Nanocrystal superlattices are finally made of the most commercially relevant semiconductor, silicon. These sterically-stabilized nanocrystals self-assemble into face-centered cubic superlattices (see picture). Their thermal stability is much more robust than other types of…
Abstract Poly(ε‐caprolactone) (PCL)‐based thermoreversible networks with self‐healing properties were prepared through Diels–Alder (DA) and retro‐DA reactions. Bis‐ or Tris‐maleimide compounds and a series of copolymer(caprolactone‐diene) PCL X F Y ( X : degree of polymerization and Y : furan‐average functionality) wi…
In the well-developed seed-mediated growth of gold nanorods (GNRs), adding the proper amount of Cu(2+) ions in the growth solution leads to significant narrowing in the size distribution of the resultant GNRs, especially for those with shorter aspect ratios (corresponding longitudinal surface plasmon resonance (LSPR)…
