Microwave synthesis of Cr nanowires on polymeric substrate

Microwave synthesis of Cr nanowires on polymeric substrate.

Without any catalysts or feeding source gases, highly crystalline Cr nanowires were directly synthesized on a flexible polymeric substrate using microwaves and the surface of the as-grown Cr nanowires showed superhydrophobicity.

single-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate

in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...

Ferromagnetic GaN--Cr Nanowires.

Using first-principles theory, we predict ferromagnetism in Cr-doped GaN nanowires irrespective of the sites that the Cr atoms occupy. This is in contrast to Mn-doped GaN nanowires in which the magnetic coupling between the Mn atoms is sensitive to the Mn--Mn and Mn--N distances, although the ground state of Mn-doped GaN nanowires is ferromagnetic. Each Cr atom carries a magnetic moment of abou...

Microwave Assisted Synthesis, Crosslinking, and Processing of Polymeric Materials

Microwave technology has been developed primary for communication and some areas of processing such as cooking food, thawing, and curing wood and rubber. As a heat source, microwaves allow a sample to be irradiated instantly with an associated rapid heating rate. Moreover, microwaves offer a number of advantages over conventional heating such as non-contact heating (reduction of overheating of ...
