Abstract In the quest to decipher chain of life from molecules cells, biological and biophysical questions being asked increasingly demand techniques that are capable identifying specific biomolecules in their native environment, can measure biomolecular interactions quantitatively, at smallest possible scale space time, without perturbing system under observation. The interaction light with of...

Binary nano-composites of Pt and nano-carbon (NC) and Pt and multiwalled carbon nanotube (MWCNT) have been prepared with varied compositions ranging between 20 and 80wt% Pt and investigated them as electrocatalysts for methanol oxidation. The study shows that with the increase in wt% of NC, the apparent electro-catalytic activity of the composite catalyst increases initially, reaches maximum at...

It is reported that the ductility and strength of a metal matrix composite could be concurrently improved if the reinforcing particles were of the size of nanometers and distributed uniformly. In this paper, we revealed that gas atomization solidification could effectively disperse TiB2 nanoparticles in the Al alloy matrix due to its fast cooling rate and the coherent orientation relationship b...

Three-dimensional nano-biointerface has been emerging as an important topic for chemistry, nanotechnology, and life sciences in recent years. Understanding the exchanges of materials, signals, and energy at biological interfaces has inspired and helped the serial design of three-dimensional nano-biointerfaces. The intimate interactions between cells and nanostructures bring many novel propertie...

in this research, the effect of different biopolymers such as polyethylene glycol (peg) and polyvinylalcohol (pva) on synthesis and characterization of polymer/cobalt ferrite (cf) nano-composites bymechanical alloying method has been systematically investigated. the structural, morphological andmagnetic properties changes during mechanical milling were investigated by x-ray diffraction (xrd),fo...

Wood is a naturally renewable material with both continuous and isolated pore systems. Wood-composite panels have the privilege of offering a homogeneous structure to be used as constructional and structural materials. However, its nature makes it susceptible to biological wood-deteriorating agents, water absorption and thickness swelling, fire, etc. Using nano-materials are very easy in the wo...
