Electrophoretic process was applied to the deposition of carbon nanotubes on the surface of carbon fabrics in order to enhance the properties of CNT/carbon fabric hybrid composites. Carbon fabrics were modified by two methods: Cu deposition by cathodic method and Cu coating by thermal vaporization method. CNTs were modified by PEI and oxidation treatment. The effects of carbon fabric and CNTs m...

High-quality DNA extraction plays an important role to make sharp bands in the gel electrophoresis and also produces clean chromatograms. Usually, DNA extract is delivered using the modified CTAB method but this method cannot obtain high-quality DNA for molecular analysis from old dried leaves of Bellevalia due to having different chemical compounds which inhibit to obtain a clear DNA extractio...

A mathematical model describing the transport and kinetics of substrate and redox mediator in surface deposited films of finite thickness is described. These bio-catalytically active chemically modified electrodes comprise redox enzymes immobilized in a highly dispersed mesh of single walled carbon nanotubes (SWNT) which are in turn immobilized on a support metal surface. A small molecule redox...

Background: In light of severe and growing shortages of clean water and the rising environmental pollution in many countries, seawater desalination has been an effective method to produce freshwater. Cationic membranes have enabled environmental scientists to effectively remove toxic heavy metals from wastewater and to regenerate freshwater. Methods: We used a novel method, involving electro- ...

Using asymmetric catalysis to simultaneously form carbon-carbon bonds and generate single isomer products is strategically important. Suzuki-Miyaura cross-coupling is widely used in the academic and industrial sectors to synthesize drugs, agrochemicals and biologically active and advanced materials. However, widely applicable enantioselective Suzuki-Miyaura variations to provide 3D molecules re...

In this work, we report a new, general synthetic approach that uses heat driven benzoin radicals to grow ultrathin copper nanowires with tunable diameters. This is the first time carbon organic radicals have been used as a reducing agent in metal nanowire synthesis. In-situ temperature dependent electron paramagnetic resonance (EPR) spectroscopic studies show that the active reducing agent is t...

Galactomannans are versatile macromolecules with broad industrial potential. The influence of changes in the chemical structures and respective bioactivities these polysaccharides have been extensively studied. derivatives obtained by sulfation, complexation, phosphorylation most studied biological properties galactomannans. shown several pharmacological activities such as antiviral, antimicrob...

The crude methanolic extract of Averrhoa bilimbi Linn. (Oxalidiaceae) fruits and its different fractions have been investigated for the evaluation of in vitro cytotoxic potential. The dried and powder fruits were extracted with methanol at room temperature and the concentrated methanolic extract was fractionated by the modified Kupchan partitioning method to provide pet-ether, carbon tetrachlor...

During recent years carbon nanotubes (CNTs) have been attracted by many researchers as a drug delivery carrier. CNTs are the third allotropic form of carbon-fullerenes which were rolled into cylindrical tubes. To be integrated into the biological systems, CNTs can be chemically modified or functionalised with therapeutically active molecules by forming stable covalent bonds or supramolecular as...
