ZnO:Mn nanostructures are important diluted magnetic materials, but their electronic structure and magnetic origin are still not well understood. Here we studied the time-delayed and power-dependent photoluminescence spectra of Mn(II) doped ZnO nanowires with very low Mn concentration. From the time-delayed emission s…
Process analytical technologies (PATs) have played an important role in process development and optimization throughout the pharmaceutical industry. Recent new PATs, including in-process video microscopy (PVM), a new generation of focused-beam reflectance measurement (FBRM), miniature process IR spectroscopy, and a fl…
Porous silicon nanoparticles (PSiNPs) as drug nanocarriers have been widely applied in the field of nanomedicine. However, a major challenge in PSiNP-based drug delivery systems is the fabrication of novel nanocarriers with high stability under physiological conditions, efficient loading and controlled release of ther…
We report ab initio calculations of electronic transport properties of heterostructure based on MoS2 nanoribbons. The heterostructure consists of edge hydrogen-passivated and non-passivated zigzag MoS2 nanoribbons (ZMoS2NR-H/ZMoS2NR). Our calculations show that the heterostructure has half-metallic behavior which is i…
ABSTRACT In the present study, silver ions were incorporated into a poly‐(l‐lactide) (PLA) matrix by a solvent casting technique using different solvents and glycerol as plasticizer. The effect of the different formulations on the morphology, thermal, mechanical and color properties were first evaluated. Additionally,…
In this work, the copper films were deposited on quartz substrates by DC magnetron sputtering method and then, the prepared films were annealed in air atmosphere at different annealing temperatures. Before annealing, some of the copper films, treated by oxygen plasma, for comparison of the results. The structural and…
The solubility of tris(hydroxymethyl)aminomethane (TRIS) in various mass fractions of water + methanol solvent mixtures at (293.2, 298.2, 303.2, 308.2, and 313.2) K was measured using a laser monitoring technique. The generated data were mathematically represented using the Jouyban–Acree model. The back-calculated mol…
Current pulse because of positive corona discharge is a main source of radio interference (RI). An accurate measurement of the original corona pulse is necessary to study corona‐generated RI. However, the corona pulse is likely to be distorted by either LC oscillation or reflection. In this study, an experiment system…
Au/Pd octopods were synthesized with enhanced sample homogeneity through the use of aromatic additives. This increase in sample monodispersity facilitates large-area periodic assembly of stellated metal nanostructures for the first time. The aromatic additives were also found to influence the structures of the stellat…
Polyurethane was linked to graphite modified with a phenol or 4-phenylethanol group on its surface, and the composite polymer was characterized regarding its thermal, spectroscopic, mechanical, and shape-memory properties as well as its electric conductivity. Graphite as a filler was covalently linked to a polyurethan…
Synthesis and characterization of copolymer obtained by grafting acrylamide onto hydrolyzed potato starch and its application in cotton yarn sizing were presented in this work. Some process parameters of starch hydrolysis and grafting, like as hydrolysis yield, grafting yield, grafting percentage, graft efficiency, an…
Fluorescent gold clusters (blue emitter) have been judiciously utilized to initiate an energy transfer process as a donor to the green emitting riboflavin (acceptor) and then riboflavin relays the energy transfer to the red emitting dye Rhodamine B in a controlled fashion to generate white light emission in a novel th…
In this review, a particular emphasis is put on the integration of porous silicon in microfuel cells. After a general description of porous silicon morphologies and etching principles, we describe microfuel cell working and requirements. Then, among silicon-based miniaturized fuel cells, we will show how porous silico…
Abstract In the three‐dimensional (3D) extracellular matrix (ECM), the influence of nanofiber chirality on cell behavior is very important; the helical nanofibrous structure is closely related to the relevant biological events. Herein, we describe the use of the two enantiomers of a 1,4‐benzenedicarboxamide phenylalan…
Significant Tumor Growth Inhibition from Naturally\nOccurring Lipid-Containing Polymer Prodrug Nanoparticles Obtained\nby the Drug-Initiated Method
Adsorption of small biomolecules onto the surface of nanoparticles offers a novel route to generation of nanoparticle assemblies with predictable architectures. Previously, ligand-exchange experiments on citrate-capped gold nanoparticles with the amino acid arginine were reported to support linear nanoparticle assembl…
This article evaluates the role of cellulosic fillers in a synthetic polymer matrix like polymethylmethacrylate (PMMA) when incorporated by in situ suspension polymerization technique. Cellulose micro/nanofibers (CNF) were extracted from jute fibers and chemically modified with maleic anhydride (MACNF) to increase the…
Colloidal "dot-in-bulk" nanocrystals (DiB NCs) consist of a quantum confined core embedded into a bulklike shell of a larger energy gap. The first reported example of this class of nanostructures are CdSe/CdS DiB NCs that are capable of producing tunable two-color emission under both weak continuous-wave optical excit…
A room-temperature high-pressure synthesis method is proposed as an alternative way to induce nanoscale structural disorder in the bulk thermoelectric CuInTe2 matrix. This disorder stems from the coexistence of distinct domains with different degrees and geometries of disorder at Cu/In cation sites. The lattice therma…
Compact spinning is one of the most important improvements of traditional ring spinning, which is implemented by adding a fiber condensing device to condense the fiber bundle and decrease the spinning triangle. Pneumatic compact spinning is the most widely used compact spinning method at present. Compact spinning with…
