Event - Web Site Updated

Friday, December 23, 2011 - It is my deepest pleasure to introduce the presentation of this updated and upgraded website. Although IQa started in 2003, its website has remained essentially unaffected. However, I have been excited by the development of the web2py framework which gracefully marries Apache with Python and PostgreSQL. I should be able to present and deliver more dynamic content with greater user interaction.

Thursday, March 17, 2011 - Tektronix has contributed their AFG3252 240 MHz 2-Channel Arbitrary Function Generator to the PDP. It will be used to upgrade the Phase IV Dielectric Spectrometer (P4DS), a broad frequency range, high-tolerance detector that will be used as a spectrometer, in the frequency domain, or a DSP lock-in amplifier, in the time domain, while coupled to NI LabView. more...

Event - Research Hiatus Terminated

Friday, January 14, 2011 - After a long hiatus from research, our principle investigator, Stephen Lukacs, returns to the Peptide Dynamics Project with new ideas and approaches to creating better dielectric spectrometers to investigate the intramolecular component dipole moments of peptides and proteins. Lets see if we can't find that elusive signal.

Scientific Publication - Noise-Rejection Techniques for Impedance and Dielectric Spectrometers Using Ubiquitous Test and Measurement Equipment

Wednesday, January 03, 2007 - This work was submitted on December 18th and accepted by the prestigious journal Review of Scientific Instruments, a publication of the American Institute of Physics.

Stephen J. Lukacs, Review of Scientific Instruments, 78(3), 34703:1-6, (2007).

Abstract - This work encompassed the development for a frequency-domain impedance and dielectric spectrometer using ubiquitous test and measurement equipment, i.e., signal generators and digital oscilloscopes. Various methods of amplification, noise-rejection, and computations were employed to achieve the desired goals. The frequency range of 100 mHz to 1 MHz was tested using air capacitors of 3.7 and 14.5 pF and an applied voltage range of 10 to 300 mV. The multi-channel instrument produced a stable and reproducible dual-phase (real and imaginary or magnitude and phase) current sensitivity of 250 fA with an average phase stability of less than 0.5 degrees (tan(delta) < 10-2), and a single-phase (magnitude only) current sensitivity of 60 fA.

These drivers include the amplifier's unique SNAP and FAST implementations of simultaneously querying the real (in-phase) and imaginary (quadrature) components of the detector. These drivers, and an example application, will fill a necessary void when interfacing these amplifiers to a PC. Download Driver...

Equipment Contribution - Infinite Quantum

Tuesday, August 15, 2006 - Infinite Quantum, the developers of Fleet Dynamics, has donated a Stanford Research SR830 Lock-In Amplifier to the PDP. This amplifier will be converted into an impedance/dielectric spectrometer with a frequency range of 1 mHz to 100 kHz and a current sensitivity down to 2 fA. This equipment will prove vital to understanding the dielectric responses of peptides and proteins.

Equipment Contribution - Fluke

Thursday, June 22, 2006 - Fluke has contributed an PM6306 RCL Meter and a 396 Arbitrary Waveform Generator to the PDP. The RCL meter will standardize new sample cells, and measure the conductivity of new chemical samples to standardize sample preparation. The latter is critical because an increased conductivity will obscure the dielectric signals of the peptides and proteins. more...

Research Proposal - Dielectric Spectrometers II & III (DS2 & DS3) Proposal

Saturday, June 17, 2006 - After the DS2 Proposal was create, below, it was realized that the DS3 can be amalgamated with the DS2 using a common temperature circulator, computer, and software. By combining the common components of the DS2 with the DS3, over $15,000 can be saved while increasing the overall capability and point-of-view of the observations. The DS3 will include capabilites to study fast transient behavior in peptides and proteins while the DS2 provides highly sensitive change-of-state studies. more...

Research Proposal - Dielectric Spectrometer II (DS2) Proposal

Wednesday, June 14, 2006 - The second dielectric spectrometer (DS2) has been proposed for the PDP. The essential approach is to create a sensitive and precise instrument to study the temperature-dependent dielectric signals from peptides and proteins at a fraction of the cost than commercial spectrometers. more...
