Interfaces features play a dominant role in the improved behavior that polymer nanocomposites exhibit. This review presents theories and models that interpret the physical, chemical and electrical structure of interfaces. Several proposed models clarify the phenomena and properties of nanocomposites based on the interfaces characteristics. Free Access

This review focuses on the synthesis, biological and pharmacokinetic properties of dendrimers, a relatively new class of nanoparticles. Furthermore, it deals with a wide variety of applications of these molecules, mainly concentrating on their potential use as nanocontainers for controlled delivery of pharmaceutically active compounds. This article also deliberates on dendrimers’ development and commercial use in various life science applications. Free Access

Long-range ordered nanoporous aluminum oxide pattern via guided anodization technique in combination with lithographic techniques has been investigated. In addition, modified anodization process can significantly change the resultant pore geometry, which will be of great interest in realizing advanced devices including biomedical and magnetic recording applications.

It has been calculated that the coupling strength between a metallic parabolic quantum dot and two semi-infinite conducting leads attached to the dot, starting from considerations on the hopping matrix element relative to nearest-neighbor atomic sites. The above calculation has been done for maximum electrical conductance through the dot. The maximum conductance has been actually determined. In addition, electron off-resonant conduction has been examined quantitatively. In fact, the density of off-resonant conduction states and the number of these states have been evaluated. Our formulation is consistent with experimental data. Free Access

In this paper, nanocrater machined by the Nano-EDM process on a gold nanofilm is simulated under practically experimental conditions using the Computational Fluid Dynamics (CFD). Shape, dimensions and volume of the nanocraters are evaluated versus process conditions and workpiece thickness. In order to achieve a nanocrater with desired dimensions, optimum levels of process parameters can be predicted using this simulation prior to conducting the real process. This issue prevents spending extra time and cost to perform the Nano-EDM process through trial and error method.

FePt-C nanogranular films were fabricated for ultrahigh density perpendicular recording media towards 1 Tbits/in². For the optimized growth conditions, we achieved a FePt-C granular film with uniform grain size of 6.4 ± 1.5 nm, shown in the TEM image. It also has an excellent MH loop shape with a perpendicular coercivity of 20 kOe, and squareness of 1.We studied the thermal stability of the optimized film and obtained the energy barrier E_b of 340 k_BT at room temperature, meaning that excellent thermal stability as magnetic recording media.

The effects of organic solvents, concentration, decomposition temperature, and oleic acid additive were examined on the formation and structural properties of LiF nanopowders through the sol–gel process. The optimum solvent was ethanol, Li⁺ concentration was 0.5 mol/l, and the thermal decomposition temperatures was 300°C. The results showed that the morphology and average sizes of LiF particles could be controlled to prepare LiF powders with cubic morphology and nanometric sizes under 100 nm using oleic acid surfactant.

We report the exploration of PEDOT:PSS/SWCNTs as a material for the hole transport layer of polymer solar cells. The electrical conductivity of PEDOT:PSS/SWCNT film was enhanced as compared to that of PEDOT:PSS because of the carrier transport pass through SWCNTs. Moreover, we have fabricated polymer solar cells with the hole transport layer of PEDOT:PSS/SWCNTs and demonstrated the improvement of a fill factor and short circuit current density in the polymer solar cells with the hole transport layer of PEDOT:PSS/SWCNT as compared to the PEDOT:PSS.

In this study, we have explored the multifunctional hydroxycamptothecin (HCPT)-capped Fe₃O₄ nanoparticles efficiently targeting for adriamycin-resistant K562 cells (KA cells), inducing apoptosis, making hole on KA cell membrane, photothermal therapy and low hemolysis activity.

In this paper, a novel and shape-controlled synthesis method for uniformly-shaped poly(p-phenylenediamine) microparticles was developed using (NH₄)₂S₂O₈ as an oxidant. It is interesting that the morphologies of PpPD varied from nanofibers to nanospheres and nest-like microspheres by tuning the pH of solution. Result showed that the PpPD nanofibers were dimer and the nanosized oligomer crystallites served as starting templates for the nucleation of PpPD nanofibers.
