At the Product Quality Research Institute (PQRI) Workshop held last January 14-15, 2014, participants from academia, industry, and governmental agencies involved in the development and regulation of nanomedicines discussed the current state of characterization, formulation development, manufacturing, and nonclinical s…
The generalized Peierls tight-binding model is developed to study multilayer graphenes. For an $N$-layer system, there are $N$ groups of conduction and valence Landau levels. Each group is clearly specified by the corresponding sublattice. The Landau-level spectra strongly depend on the stacking configuration. ABC-sta…
The ambipolar behavior limits the performance of Schottky-barrier-type graphene nanoribbon field-effect transistors (SB-GNRFETs). We propose an asymmetric gate (AG) design for SB-GNRFETs, and show that it can significantly reduce the IOFF. Simulation results indicate at least 40% and 5× improvement in the subthreshold…
We have demonstrated that amide-based dendrimers functionalized with the membrane-interacting peptide gH625 derived from the herpes simplex virus type 1 (HSV-1) envelope glycoprotein H enter cells mainly through a non-active translocation mechanism. Herein, we investigate the interaction between the peptide-functional…
PECVD Synthesis of Silicon Carbonitride Layers Using Methyltris(diethylamino)silane as the New Single-Source Precursor, Fainer, N. I., Plekhanov, A. G., Golubenko, A. N., Rumyantsev, Yu. M., Rakhlin, V. I., Maximovski, E. A., Shayapov, V. R.
Abstract A layered perovskite EuBaCo 2 O 5+δ (EBCO) has been prepared by a solid‐state reaction, and evaluated as potential cathode for intermediate‐temperature solid oxide fuel cells. Structural characterizations are determined at room temperature using powder X‐ray diffraction and transmission electron microscopy te…
Targeted drug delivery system using nanoparticles is a promising strategy for efficient Photodynamic therapy (PDT) as they have the potential to overcome the problems of photosensitizer and enhance the effectiveness and specificity of PDT. In this study, Protoporphyrin IX (PpIX) conjugated gold nanoparticles were synt…
A novel organic/graphene/inorganic -heterostructure, consisting of a graphene layer encapsulated by n- and p-type photoactive materials with complementary absorptions, enables the control of dual n- and p-typed transport behaviors of a graphene transistor under selective UV or visible light illumination. A graphene-ba…
The particle size of SAED nanostructured particles, which are good candidates for the replacement of conventional micrometer-sized phosphors, can be tuned <italic>via</italic> a dry grinding process of initially synthesised nanostructured sheets with a thickness ≤ 1 μm obtained by combustion.
This paper presents the analytical solutions for the size-dependent static analysis of the functionally graded (FG) beams with various boundary conditions based on the nonlocal continuum model. The nonlocal behavior is described by the differential constitutive model of Eringen, which enables to this model to become e…
Abstract Ionogels (IGs), also termed ion gels, are functional hybrid materials based on an ionic liquid (IL) and a polymeric, hybrid, or inorganic matrix. IGs combine the properties of the matrix such as mechanical strength with IL properties like high ionic conductivity, high thermal stability, or catalytic activity.…
The use of combinations of organic additives to control crystallization, as occurs in biomineralization, is rarely investigated due to the vast potential reaction space. It is demonstrated here that combinatorial approaches led by genetic algorithm heuristics can enable identification of active additive combinations,…
Although inert in its bulk form, nanostructured gold supported on oxides has been found to be catalytically active. In many cases, the oxide promotes the activity of Au. It is now shown that in turn, nanoscale Au particles can chemically activate the solid oxide. Specifically, it was discovered that 4 nm Au nanopartic…
Poly(3,4-ethylenedioxythiophene)-(PEDOT)-functionalized reduced graphene oxide (rGO) with MnO2 nanoparticles (MnO2/PEDOT/rGO) was prepared using electrochemical methods. The MnO2/ PEDOT/rGO was obtained through the electrochemical reduction of PEDOT/GO and under electrochemical treatment in KMnO4. The PEDOT/rGO and Mn…
A novel nanocomposite has been developed using extracted cellulose from marine algae coated with conductive polypyrrole and graphene nanoplateletes. The nanocomposite fabricated via in situ polymerization was used as an electrode for a supercapacitor device. The nanocomposite material has been electrochemically charac…

The iron oxide nanoparticles synthesized at two different temperatures viz., 45 and 85 °C were characterized using techniques such as X-ray diffraction (…
Si quantum dots (Si QDs)/SiC multilayers were fabricated by annealing hydrogenated amorphous Si/SiC multilayers prepared in a plasma-enhanced chemical vapor deposition system. The thickness of amorphous Si layer was designed to be 4 nm, and the thickness of amorphous SiC layer was kept at 2 nm. Transmission electron m…
A glycine doped bis-thiourea cadmium formate (BTCF) crystal has been grown by a slow solution evaporation technique. The shifts in vibrational frequencies of different functional groups of BTCF were identified by Fourier transform infrared (FT-IR) spectral analysis. UV-visible studies were employed to assess the optic…
. Gemcitabine loaded c(RGDfE)-pMMSNs were most efficiently targeted to pancreatic cancer cells (BxPC-3). Growth inhibition of the BxPC-3 cell line was achieved in a time dependent manner consistent with observed drug release behavior. Intracellular targeted gemcitabine delivery using c(RGDfE)-pMMSNs offers a promising…
