Measured Performance of Building Integrated Photovoltaic Panels

August 1, 2001
Author(s)
Arthur H. Fanney, Brian P. Dougherty, Mark W. Davis
The photovoltaic industry is experiencing rapid growth. Industry analysts project that photovoltaic sales will increase from their current $1.5 billion level to over $27 billion by 2020, representing an average growth rate of 25%.(Cook et al. 2000)[1]. To

Molecular Engineering of a Polymer of Tetrameric Hemoglobins

August 1, 2001
Author(s)
C Fronticelli, D Arosio, K M. Bobofchak, G B. Vasquez
We have engineered, a recombinant mutant human hemoglobin, Hb prisca Β(S9C+C112G), which assembles in a polymeric form. The polymerization is obtained through the formation of intermolecular S-S bonds between cysteine residues introduced at position Β9, on

Moving the Pulsed Heating Technique Beyond Monolithic Specimens: Experiments with Coated Wires

August 1, 2001
Author(s)
Daniel Josell, D Basak, J L. McClure, Ursula R. Kattner, Maureen E. Williams, William J. Boettinger, M Rappaz
Pulsed heating experiments based on pyrometric measurement of the temperature-time history of metal specimens rapidly heated by passage of electric current have a thirty year history at NIST. In recent years, efforts have been made to move beyond the

Natural Ventilation Review and Plan for Design and Analysis Tools

August 1, 2001
Author(s)
Steven J. Emmerich, William S. Dols, James W. Axley
Natural ventilation has the potential to reduce first costs and operating costs for some commercial buildings while maintaining ventilation rates consistent with acceptable indoor air quality. While a recent surge of interest in Europe has advanced natural

Phase-Coherent Optical Pulse Synthesis From Separate Femtosecond Lasers

August 1, 2001
Author(s)
R K. Shelton, L -. Ma, H C. Kapteyn, M M. Murnane, John L. Hall, Jun Ye
We generated a coherently synthesized optical pulse from two independent mode-locked femtosecond lasers, providing a route to extend the coherent broadwidth available for ultrafast science. The two separate lasers (one centered at 760 nanometers wavelength

Problem with Submicrometer-linewidth Standards and A Possible Solution

August 1, 2001
Author(s)
James E. Potzick
Traceable linewidth measurements of tiny features on photomasks and wafers present interesting challenges. Usually technical solutions exist for the problems encountered, but traceability can be costly in time and labor. A measurement is useful only if its

Problem With Submicrometer-Linewidth Standards and a Proposed Solution

Traceable linewidth measurements of tiny features on photomasks and wafers present interesting challenges. Usually technical solutions exist for the problems encountered, but traceability can be costly in time and labor. A measurement is useful only if its

Progress Towards an International Standard for Data Transfer in Rapid

August 1, 2001
Author(s)
Lalit Patil, D Dutta, Ram D. Sriram, Kevin W. Lyons, Amba D. Bhatt, Mike Pratt, M Allahabad
This paper discusses the informational requirements of rapid prototyping and layered manufacturing (RPLM). The study is motivated by the recent decision to embark on the development of a new Application Protocol for the international standard ISO 10303

Properties of Cavity-Backed Slot-Ring Antennas at 95 GHZ

August 1, 2001
Author(s)
Shalva Nolen, Todd E. Harvey, Carl D. Reintsema, Erich N. Grossman
Slot-ring antennas with planar backshorts, designed for operation at 95 GHz, have been fabricated and their properties measured. Using optical lithography, we fabricated the slot-ring antennas, along with integrated niobium thin-film biolometers, on

Publication and Use of Large Data Sets

August 1, 2001
Author(s)
J R. Rumble
Scientific information comes in many sizes, types and quality. Because of diversity of the scientific information being published, different issues will arise in publishing different types of information electronically. In this paper, we will address

Quantum Electrodynamics in the Dark

August 1, 2001
Author(s)
John D. Gillaspy
Perhaps they're just shy, but heavy atoms seem very uncomfortalbe when most of their electrons are stripped off. In order to cover their nakedness as quickly as possible, they aggressively try to steal electrons from any source they encounter. Their

Radiometry of Low-Pressure Hg-Ar Discharges

August 1, 2001
Author(s)
Craig J. Sansonetti, Joseph Reader
New fluorescent lamp designs employ Hg-Ar discharges under operating conditions that differ significantly from those found in conventional fluorescent tubes. We have studied the radiant output of Hg-Ar discharges over a wide range of Ar pressure, Hg vapor

Raman and FTIR Spectroscopies of Fluorescein in Solutions

August 1, 2001
Author(s)
Lili Wang, A. E. Roitberg, Curtis W. Meuse, Adolfas K. Gaigalas
Raman and FTIR transform-infra red (FT-IR) spectroscopies of fluorescein in aqueous solutions have been investigated in the pH range from 9.1 to 5.4. At pH 9.1 fluorescein is in the dianion form. At pH 5.4, fluorescein is a mixture of monoanion (
