The aim was to improve the processability and reduce melt viscosity of well?known nanocomposites based on polyamide 66 (PA66) carbon nanotubes (CNT), while keeping good electrical conductivity gained after addition CNT. Thus, a nanocomposite PA66 as thermoplastic matrix 3% CNT selected. At this composition, percolated network is created material electrically conductive. approach followed graphe...

In this work, we report a green method for the synthesis of gold nanoparticles (GNP) using the aqueous extract of red tomato (Lycopersicon esculentum). We believe that citric acid and ascorbic acid present in tomato juice are responsible for the reduction of gold ions. This biosynthesized GNP in the presence of sodium dodecyl sulfate has been used as a colorimetric sensor to detect and estimate...

Coordinates-based mechanisms have proven to be useful in a peer-to-peer architecture to predict Internet network distance, even more so than the already existing IDMaps scheme. One such mechanism has been analyzed known as Global Network Positioning (GNP) to provide insight on a current state of the art technology in network distance prediction. GNP instantiates a virtual geometric space by app...

Localization microscopy has shown to be capable of systematic investigations on the arrangement and counting of cellular uptake of gold nanoparticles (GNP) with nanometer resolution. In this article, we show that the application of specially modified RNA targeting gold nanoparticles ("SmartFlares") can result in ring like shaped GNP arrangements around the cell nucleus. Transmission electron mi...

Thermal interfacematerials (TIMs) are crucial components of high density electronics and the high thermal conductivity of graphite makes this material an attractive candidate for such applications. We report an investigation of the in-plane and through-plane electrical and thermal conductivities of thin thermal interface layers of graphite nanoplatelet (GNP) based composites. The in-plane elect...

In this paper, we propose an evolutionary method to search interesting association rules. Most of the association rule mining methods give a large number of rules, and it is difficult for human beings to deal with them. We study this problem by borrowing the style of a search engine, that is, searching association rules by keywords. Whether a rule is interesting or not is decided by its relatio...

Using a gravity model, we estimate the magnitude of potential trade flows between Ireland and the five CEEC countries currently negotiating accession to the EU. We find that Irish exports were already close to their “normal” level in 1994, but that imports from the CEECs were still only half of their “normal” size. The value of estimated “normal” trade corresponds to 0.8 percent of Irish GNP. T...

This work reports a study on the effect of multiple reprocessing on the properties of poly(lactic acid) (PLA) filled with graphene nanoplatelets (GnP) compared to the melt reprocessed neat polymeric matrix. In particular, morphological, X-Ray Diffraction and Micro-Raman analyses, intrinsic viscosity measurements, thermal, rheological and mechanical tests were carried out on materials reprocesse...

NIR-dye encoded gold nanoparticles (GNP) are rapidly emerging as contrast agents in many bio-imaging/sensing applications. The coding process is usually carried out without control or a clear understanding of the metal-liquid interface properties which, in contrast, are critical in determining the type and extension of dye-metal interaction. In this paper, we investigated the effect of gold sur...

Abstract Although easily scalable, the production of graphene nanoplatelets (GNP) by means liquid‐phase exfoliation graphite flakes (GF) remains an energy‐ and time‐intensive process. In this work, we demonstrate that significant time energy can be saved in GNP when employing expanded (EG) a surfactant‐assisted liquid phase Owing to its increased interlayer distance, EG accomplished much shorte...
