The Helios Talks
out of 5 stars
25 Sep 2007 | | Contributor(s):: Joe Ringgenberg, Jeffrey B. Neaton, Jeffrey C Grossman
The energy problem is one of the most important issues that science and technology has to solve.The Lawrence Berkeley National Laboratory’s Helios Project concentrates on renewable fuels, such as biofuels, and solar technologies, including a new generation of solar photovoltaic cells and the...
MCW07 Silicon Based Nanopore Sensors for Detection of DNA Molecules
11 Sep 2007 | | Contributor(s):: Samir Iqbal, Demir Akin, Rashid Bashir
Solid-state nanopores have emerged as possible candidates for next-generation DNA sequencing devices. In this talk, we will review our recent work in development of solid-state nanopore channels that are selective towards single strand DNA (ssDNA). Nanopores functionalized with a 'probe' of...
Introduction to Self-Assembled Monolayers and Biosensors
01 Aug 2007 | | Contributor(s):: Michael Toole
Recent research concerning self-assembled monolayers (SAMs) focuses on tasks from fabrication of microelectronics to creating biosensors. This presentation will address the fundamental principles of self-assembled monolayers, formation and analysis of self-assembled monolayers, the basics of...
Oligodeoxyribonucleotide Association with Single-Walled Carbon Nanotubes
02 Aug 2007 | | Contributor(s):: Jennifer McDonald
Commercially available single-walled carbon nanotubes (SWCNTs) tend to aggregate as ropes and bundles during production making them of little use in many scientific and industrial applications. An effective technique for dispersing and solubilizing SWCNTs is required to fully utilize their...
Re-engineering a Healthy Eye Tissue to Restore Damaged Eyesight
02 Aug 2007 | | Contributor(s):: Margarita Shalaev
Age-related macular degeneration (AMD) is an eye disease that is the leading cause of blindness in the USA and Western Europe. It affects over one million people in the United States alone. One of the symptoms of AMD is a diseased Bruch’s membrane, which is an important layer in the eye. Our...
SPMW A fresh look to amplitude-modulation AFM: Force minimization, interaction measurement, and the quest for high resolution
05 Jan 2007 | | Contributor(s):: Udo D. Schwarz
Frequency modulation atomic force microscopy (FM-AFM) has been able to deliver high-resolution atomic-scale images in ultrahigh vacuum for over one decade. In addition, there have been recent reports where atomic resolution has been achieved in air and liquids using FM-AFM . Achieving...
On the Cross Roads of Biology and Nanotechnology – Selective DNA Nanopore Sensors
21 Mar 2007 | | Contributor(s):: Samir Iqbal
The ability to manipulate and identify the properties of singlebiological molecules with the potential of characterizing biologicalprocesses at the most fundamental levels can significantly facilitaterapid diagnostics and therapeutics. Fabrication of solid-statedevices investigating bacteria,...
From Research to Learning in Chemistry through Visualization and Computation
17 May 2007 | | Contributor(s):: Eric Jakobsson
Modern chemistry research and high school chemistry education are separated by institutional and geographical boundaries. As such, much of secondary chemistry education is still based on the periodic table instead of the computational methods that drive current chemistry research. In this talk,...
SPMW AFM at Video Rate and Beyond
16 May 2007 | | Contributor(s):: Mervyn Miles
The particular advantages that atomic force microscopy (AFM) has over other types of microscopy are well-known, but it has the one major disadvantage of low imaging rates in conventional instruments in which each image requires typically a minute or more to collect. This has two major...
Electronics at Nano scale
06 Apr 2007 | | Contributor(s):: Rakesh Kumar gupta
Current research on nanoelectronics is extremely diverse. Exiting technology of optical lithography used for the fabrication of electronics components,devices and systms already reached to their extreme limits. The devises with minimum feature dimensions less than 50nm and below this are almost...
25 Dec 2006 | | Contributor(s):: Rakesh Voggu
DNA has been well known for over 50 years as the predominant chemical for duplication and storage of genetic information in biology. Now DNA has also been recognized as a useful building material in the field of nanotechnology. DNA provides basic building blocks for constructing functionalized...
