Ultrasound-Induced Calcein Release From eLiposomes
(Elsevier, 2012)
Ultrasound is explored as a method of inducing the release of encapsulated materials from eLiposomes, defined as liposomes containing emulsion droplets. Emulsions were formed using perfluorohexane and perfluoropentane. ...
Non-Viral Gene Transfection with Ultrasound: Is 100% Transfection Possible?
(American Scientific Publishers, 2012)
Ultrasound has been used as a modality to enhance the transfection of cells, purportedly via entry of genetic material through defects in the cell membrane produced by bubble cavitation events. A mathematical model was ...
Mapping of Embedded Functionalized Carbon Nanotubes in Poly(vinyl alcohol)/Nanotube Composite Using Electrostatic Force Microscopy
(Taylor & Francis, 2012)
In the present study, electrostatic force microscopy (EFM) was used as a nondestructive tool for mapping individual functionalized single-wall carbon nanotubes (SWCNTs) incorporated in a poly(vinyl alcohol) (PVA)/CNT ...
Matrix Encoding for Data Hiding Using Multilayer Video Coding and Transcoding Solutions
(Elsevier, 2012)
This paper proposes a multitier data hiding solution in MPEG video using matrix encoding. In the first tier of the proposed solution, raw video is encoded into two layers using multilayer Signal to Noise Ratio (SNR) encoding. ...
Phase transitions of nanoemulsions using ultrasound: Experimental observations
(Elsevier, 2012)
The ultrasound-induced transformation of perfluorocarbon liquids to gases is of interest in the area of drug and gene delivery. In this study, three independent parameters (temperature, size, and perfluorocarbon species) ...
Data Hiding in MPEG Video Files Using Multivariate Regression and Flexible Macroblock Ordering
(IEEE, 2012)
This paper proposes two data hiding approaches using compressed MPEG video. The first approach hides message bits by modulating the quantization scale of a constant bitrate video. A payload of one message bit per macroblock ...
Gas Phase Deposition of Trichloro(1H,1H,2H,2H-perfluorooctyl)silane on Silicon Dioxide, by XPS
(American Vacuum Society, 2012)
Monolayers of trichloro(lH,1H,2H,2H-perfluorooctyl)silane, Cl3SiCH2CH2(CF2)5CF3, were deposited via chemical vapor deposition onto the native oxide layer on silicon after plasma-cleaning. The samples have high hydrophobicity, ...
Design and simulation of a UOIT copper–chlorine cycle for hydrogen production
(Wiley, 2012)
A design and simulation study of the four-step copper–chlorine (Cu–Cl) cycle using Aspen Plus software (Aspen Technology Inc., Cambridge, MA)is reported. The simulation consists of four main sections: hydrolysis, ...
Folic Acid Quenches Doxorubicin Fluorescence Letter to the Editor
