Scientific Ethics and the Signs of Voodoo Science
out of 5 stars
18 Oct 2006 | | Contributor(s):: Andrew S. Hirsch
Until recently, the issue of research ethics had not been a subject of explicit discussion within the Physics community. Over the past ten years, however, documented cases of scientific fraud have brought this issue to center stage. We will explore, through case studies, some examples ranging...
Understanding Phonon Dynamics via 1D Atomic Chains
04 Apr 2006 | | Contributor(s):: Timothy S Fisher
Phonons are the principal carriers of thermal energy in semiconductors and insulators, and they serve a vital role in dissipating heat produced by scattered electrons in semiconductor devices. Despite the importance of phonons, rigorous understanding and inclusion of phonon dynamics in...
Conversion of Movie Files to Flash SWFs for Use in Breeze Presentations
17 Aug 2006 | | Contributor(s):: Rick DeSutter, Joseph M. Cychosz
Conversion of Animated GIFs to Flash SWFs for Use in Breeze Presentations
This guided tutorial explains the process of how to convertan animated GIF into a Flash SWF which can then be inserted into a Adobe Macromedia Breeze presentation. The tutorial uses Adobe Macromedia Flash MX to perform the conversion process.
Insertion of Flash SWFs into Breeze Presentations
This guided tutorial explains the process for inserting movie files as Flash SWFs into your Adobe Macromedia Breeze presentation. Guided tutorials are available which explain the process of how to create Flash SWFs from movie files such as (.mov, .avi, .wmv, etc.) or fromanimated GIFs.
Microphone Selection and Comparison: Hear the Difference
08 Aug 2006 | | Contributor(s):: Joseph M. Cychosz
Selecting a microphone can be a difficult task.For presentations, the quality is very much dependent upon the audio clarity and quality of the naration. For meetings, quality can be somewhat less. This presentation gives an audio comparison of the various options listed with our Microphone...
Nanotubes and Nanowires: One-dimensional Materials
17 Jul 2006 |
What is a nanowire? What is a nanotube? Why are they interesting and what are their potential applications? How are they made? This presentation is intended to begin to answer these questions while introducing some fundamental concepts such as wave-particle duality, quantum confinement, the...
How to Breezify Your Presentation and Publish it on the nanoHUB
09 Jul 2006 | | Contributor(s):: Joseph M. Cychosz
This presentation gives a detailed overview of the process of creating an online presentation for the nanoHUB. It describes how to use Adobe-Macromedia's Breeze presentation tool in conjuction with Microsoft Powerpoint to create a narriated presentation, and how to upload it to the nanoHUB.
Exploring Electron Transfer with Density Functional Theory
11 Jun 2006 |
This talk will highlight several illustrative applications of constrained density functionaltheory (DFT) to electron transfer dynamics in electronic materials. The kinetics of thesereactions are commonly expressed in terms of well known Marcus parameters (drivingforce, reorganization energy and...
What is "Nanofluidics"? or The Nano-izing of Fluid Mechanics
28 Jun 2006 | | Contributor(s):: Steve Wereley
Micro- and nanoscaled fluid mechanics are rapidly emerging as important supporting fields in biomedical technology, nanotechnology, etc., as well as being important fields of study in their own right. Despite the common use of these terms in the literature, the fluid behavior at these small...
Giving Talks and Posters That People Would Actually Like to See
28 Jun 2006 | | Contributor(s):: Jerry M. Woodall
Other than getting a college degree, being able to communicate technical results to non experts (and even experts) in a simple and easily understandable way iscritical to a future successful career path.To this end I will discuss the elements of how to prepare both good power pointand poster...
Vector Free Energy Calculation with Adaptive Biasing Force
18 Jun 2006 | | Contributor(s):: Eric F Darve
This presentation discusses recent numerical methods to calculate thefree energy as a function of a reaction coordinate for bio-molecules.Free energy is often called potential of mean force and represents theeffective potential experienced by a generalized coordinate for abio-molecular system....

06 Jun 2006 | | Contributor(s):: Kurtis Cantley, Mark Lundstrom
This tutorial is an introduction to the nanoMOS simulation tool for new users. Descriptions of input and output parameters are included, along with new features associated with the Rappture interface. There are also descriptions of nine examples that are loadable in the new version to help the...
19 May 2006 | | Contributor(s):: Mikhail A. Noginov
Random lasers are the simplest sources of stimulatedemission without cavity, with the feedback provided by scattering in a gain medium. First proposed in the late 60’s, random lasers have grown to a large research field.This lecture reviews the state of the art of random lasers,provides an...
MATLAB DOs and DON'Ts
14 May 2006 | | Contributor(s):: Dmitri Nikonov
Matlab is widely used for simulations but is believed to be unsuitable for complex projects and to produce slow-running software tools. The presentation argues that blind copying of methods typical of C and Fortran is responsible for such inefficiencies; the presentation teaches avoidance of...
Switching Energy in CMOS Logic: How far are we from physical limit?
24 Apr 2006 | | Contributor(s):: Saibal Mukhopadhyay
Aggressive scaling of CMOS devices in technology generation has resulted in exponential growth in device performance, integration density and computing power. However, the power dissipated by a silicon chip is also increasing in every generation and emerging as a major bottleneck to technology...
