Aberrant signaling of the epidermal growth factor receptor (EGFR) is common to a variety of human cancers and is also found to be over-expressed in most cases of non-small cell lung cancer. For the development of a molecularly targeted therapy, cetuximab-conjugated nanoparticles (immunonanoparticles, INPs) are designe…
The analogy between electromagnetic waves and ballistic electrons within the Kane's model is developed and subsequently applied to a theoretical description of a quantum version of a metamaterial planar lens. Restrictions imposed on the perfect lens and the poor man's lens by available semiconductor band structures ar…
Low energy optical modes of MBE-grown In1-xGaxN thin films with different values of x are investigated using Raman spectroscopy. We also studied the influence of Raman excitation frequency using red and green lasers on scattering intensity of various Raman modes. For those In1-xGaxN alloys whose bandgap energy is clos…
We have coupled electron microscopy and energy dispersive spectroscopy experiments with \textit{ab-initio} modeling to study the solubility and diffusion of Au in Bi$_2$Te$_3$. We found that thermal annealing of Au films results in Au concentrations in Bi$_2$Te$_3$ above the previously reported solubility limit. The t…
A low-cost and simple recycling process of waste thermoelectric modules has been investigated using chemical reduction methods. The recycling is separated by two processes, such as dissolving and reduction. When the waste thermoelectric chips are immersed into a high concentration of <TEX>$HNO_3$</TEX> aqueous solutio…
The main theme of this paper is to describe the mechanical properties of multi-walled carbon nanotube (MWCNT)/epoxy resin composites with the variation of MWCNT fillers. The work tried to achieve a uniform distribution of MWCNT filler in the epoxy matrix by modifying the hardener and mixing conditions. The MWCNT fille…
It is aimed to investigate vibrations of an embedded nanoplate subjected to biaxially applied loads and a moving nanoparticle. To this end, the nanoplate and the moving nanoparticle in order are modeled via nonlocal Kirchhoff plate theory and a rigid body. The mass weight of the moving nanoparticle, and its friction w…
This paper reports substituent effects on the conformational changes in polyaniline (PAni) derivatives. PAni, poly-o-toluidine (POT), and poly-o-anisidine (POA) were formed by potentiodynamic electropolymerization in aqueous solution containing (+)-camphorsulfonic acid (CSA) as a dopant. UV-Vis spectroscopy and cyclic…
Nanocrystalline SiC ceramics was fabricated by spark plasma sintering (SPS) using Al2O3 and TiO2 additives with the composition of 5, 10 and 20 mass% (Al2O3–TiO2). XRD analysis revealed formation of TiC phase. And also mullite phase with preferred orientation was detected in SiC with 20 mass% addition. From TEM observ…
ABSTRACT The main objective of this work has been to study the effects of copolymer microstructure, both chemical and physical, on the microporosity, in vitro hydrolytic degradability and biocompatibility of electrospun poly( l ‐lactide‐ co ‐ε‐caprolactone), PLC, copolymer tubes for potential use as absorbable nerve g…
A layered perovskite of Dion-Jacobson phase, <TEX>$RbLaTa_2O_7$</TEX>, was successfully exfoliated into colloidal suspension via successive ion-exchange and intercalation reaction. The pristine perovskite <TEX>$RbLaTa_2O_7$</TEX> was synthesized by conventional solid-state reaction, and then, it was ion-exchanged with…
Nanoscale dimensions and remarkable properties of carbon nanotubes make them promising building blocks for nanoelectronics. One requirement is the need to manipulate single or multiple carbon nanotubes to bridge electronic conductors. In this paper, multi-walled carbon nanotubes with a variety of sizes are assembled o…
Mesoporous In 2 O 3– y materials have been implanted using Co ions to induce a moderate ferromagnetic response at room temperature, forming a “mesoporous oxide-diluted magnetic semiconductor” (MODMS). X-ray photoemission spectroscopy (XPS) reveals that implantation results in up to 1 at. % Co (for 6 × 10 15 ions/cm 2…
A composite-hydroxide mediated method was employed to synthesize barium manganite nanorods. Diameter, surface smoothness and uniformity of these nanorods were optimized by varying reaction temperature and reaction time. The rods with an average diameter of 200 nm and length of 1–1.5 μm were obtained at optimum conditi…
A novel sol-gel method was implied to prepare CuO-doped ZnO nanoparticles. XRD and SEM techniques were used to characterize the CuO-doped ZnO sample. The photocatalytic degradation of Lidocaine HCl was investigated by two methods. The degradation was studied under different conditions such as the amount of photocataly…
Curing behavior of an unsaturated polyester (UP) resin containing 3 wt % Cloisite 10A (UP/10A) and 3 wt % Cloisite 30B (UP/30B) catalyzed with methyl ethyl ketone peroxide (MEKP) as initiator and promoted by cobalt naphthenate as accelerator was investigated by dynamic differential scanning calorimetry (DSC) at heatin…
Optimization of the mechanical properties is necessary in the applications of electrospun nanofibrous matrices. In this work, mechanical reinforcement of electrospun nanofiber membranes of water‐soluble polymer by the incorporation of commercial nanodiamonds (NDs) was studied. Through an ND/poly(vinyl alcohol) (ND/PVA…
In this article, high thermally conducting polymer composites were prepared by low temperature expandable graphite (LTEG) filling polyamide 6 (PA6) via an in situ exfoliation process during melt blending. Thermal conductivity of the composites was measured by hot disk method and a very high value of 32.33 W/mK was obt…

Mechanical and rheological tests were effectuated, to illustrate the effect of woven fibers on the mechanical and viscoelastic properties at 0°, 15°, 30°, and 45° dir…
WS2 nanoribbons have been synthesized by chemical unzipping of WS2 nanotubes. Lithium atoms are intercalated in WS2 nanotubes by a solvothermal reaction with n-butyllithium in hexane. The lithiated WS2 nanotubes are then reacted with various solvents--water, ethanol, and long chain thiols. While the tubes break into p…
