Anisotropy - Research News and Information
Wednesday, January 07, 2009
Definition of 'Anisotropy'A physical property showing different values in relation to the direction in or along which the measurement is made. The physical property may be with regard to thermal or electric conductivity or light refraction. In crystallography, it describes crystals whose index of refraction varies with the direction of the incident light. It is also called acolotropy and colotropy. The opposite of anisotropy is isotropy wherein the same values characterize the object when measured along axes in all directions. |

Kernohan's notch phenomenon is the ipsilateral hemiplegia caused by compression of the contralateral cerebral peduncle against the tentorial edge by a supratentorial mass. Diffusion tensor imaging (DTI) and transcranial magnetic stimulation (TMS) ... Read more...
Carbon nanotube arrays with strong shear binding-on and easy normal lifting-off.
8 Oct 2008 The ability of gecko lizards to adhere to a vertical solid surface comes from their remarkable feet with aligned microscopic elastic hairs. By using carbon nanotube arrays that are dominated by a straight body segment but with curly entangled top, ... Read more...
Quantum dots for single-pair fluorescence resonance energy transfer in membrane- integrated EFoF1.
29 Sep 2008 spFRET (single-pair fluorescence resonance energy transfer) with organic fluorophores has been used to demonstrate rotation of the subunits gamma and epsilon in membrane-integrated FoF1 during proton transport-coupled ATP synthesis. Owing to the ... Read more...
