Kong X, Hellermann GR, Zhang W, Jena P, Kumar M, Behera A, Behera S, Lockey R, Mohapatra SS.
PMID: 20525130
Allergy Asthma Clin Immunol. 2008 Sep 15;4(3):95-105. doi: 10.1186/1710-1492-4-3-95. Epub 2008 Sep 15.

: The use of chitosan nanoparticles as carriers for expression plasmids represents a major improvement in gene expression technology. We demonstrated previously that treatment with chitosan interferon-gamma (IFN-gamma) plasmid deoxyribonucleic acid (DNA) nanoparticles (chitosan interferon-gamma nanogene [CIN]) led to...

PMID: 21711845
Nanoscale Res Lett. 2011 Apr 11;6(1):320. doi: 10.1186/1556-276X-6-320.

In this article, we report on the visible absorption, photoluminescence (PL), and fast PL decay dynamics from freestanding Si nanocrystals (NCs) that are anisotropically strained. Direct evidence of strain-induced dislocations is shown from high-resolution transmission electron microscopy images. Si...

Graphene-assisted controlled growth of highly aligned ZnO nanorods and nanoribbons: growth mechanism and photoluminescence properties.

J Nanosci Nanotechnol. 2012 May;12(5):3879-83. doi: 10.1166/jnn.2012.6144.

Rectification is observed in a single n-ZnO/p++-Si nanoheterojunction using ultra high vacuum compatible scanning tunneling microscope. The nanohetrojunctions have been grown using catalyst free vapor-solid growth of ZnO nanorods on p++-Si substarte. A high rectification ratio approximately 100 at...

Spin-lattice relaxation rates (R(1H) and R(1F)) of two nuclear species ((1)H and (19)F) are measured at different temperatures in the isotropic phase of a liquid crystal (4(')-butoxy-3(')-fluoro-4-isothiocyanatotolane-4OFTOL), over a wide range of Larmor frequency (10 kHz-50 MHz). Their dispersion...
