Tuning the charge carier concentration of graphene is one key challenges in field research. An effective solution for this to dope by organic molecules that physisorb or self-assemble on surface. Therefore, a comprehensive understanding their surface structures at molecular level realy nessesary. In contribution, we report role applied electrode potential adsorption/self-assembly such n-dope mo...

From nanotechnology point of view where conductivity is crucial, although it essential to determine the electrochemical properties Cu doped ZnO nanostructure thin films produced by spin coating, there are rare studies in literature. Therefore, this study, aim was examine thouroughly which were grown on glass substrates using a facile and cost-effective coating method. The effects dopant morphol...

Composite materials were manufactured to obtain singular properties be used as in electrochemical driven energy systems. An evaluation was performed on electro-spun nylon 6,6 fibers (Ny), with different concentrations of tetra-para-amino-phenyl porphyrin (PP) and graphene oxide (GO) composite coating over stainless steel (SS), immersed 1M H2SO4 aggressive sulfuric acid solution. Different film ...

Pembuatan karbon aktif dari Tandan Kosong Kelapa Sawit (TKS) sebagai elektroda superkapasitor sudah diteliti. Karbon dibuat proses karbonisasi dan aktivasi menggunakan Kalium Hidroksida (KOH). TKS dikarbonisasi melalui pembakaran sampel pada suhu 400°C diaktivasi dengan KOH 800°C dalam lingkungan gas nitrogen. dikarakterisasi Energi Dispersive X-Ray (EDX), Difraction (XRD), Scanning Electron Mi...

The self-assembly of molecular layers has become an important strategy in modern design of functional materials. However, in particular, large organic molecules may no longer be sufficiently volatile to be deposited by vapor deposition. In this case, deposition from solution may be a promising route; in ionic form, these molecules may even be soluble in water. In this contribution, we present a...

A new mononuclear Pt(II) complex, [Pt(DMP)(DIP)]Cl(2).H(2)O, in which DMP is 4,4-dimethyl-2,2-bipyridine and DIP is 4,7-diphenyl-1,10-phenantroline, has been synthesized and characterized by physicochemical and spectroscopic methods. The binding interaction of this complex with calf thymus DNA (CT-DNA) was investigated using fluorimetry, spectrophotometry, circular dichroism, viscosimetry and c...

This study aims at evaluating the biocompatibility of titanium surfaces modified according two different ways: (i) deposition of a bio-inert, thin film of rutile TiO(2) by chemical vapour deposition (MOCVD), and (ii) biochemical treatment with collagen gel, in order to obtain a bio-interactive coating. Behind the comparison is the idea that either the bio-inert or the bio-active coating has spe...

Volume 1 • Issue 3 • 2012 A wide range of techniques is available whereby various extraction reagents and experimental conditions are used. These techniques involve a 5step [8], 4step (BCR, Bureau Commune de Reference of the European Commission) and 6-step [13] extraction, and are thus becoming popular and adopted methods used for sequential extraction [14,15]. Several analytical methods have b...
