31. Effect of Al^d2^O^d3^ Nanolubricant on a Passively Enhanced R134a Pool Boiling Surface with Extensive Measurement and Analysis Details (NIST TN 1677)
Series: Technical Note (NIST TN)
Report Number: 1677
Topic: Energy Conservation
Published: 9/29/2010
Author: Mark A Kedzierski
Abstract: This paper quantifies the influence of Al2O3 nanoparticles on the pool boiling performance of R134a/polyolester mixtures on a Turbo-BII-HP boiling surface. Nanofluids are liquids that contain dispersed nano-size particles. A lubricant based nanoflu ...

32. Air Flow Distribution through an A-Shaped Evaporator under Dry and Wet Coil Conditions
Topic: Energy Conservation
Published: 7/11/2010
Authors: David A Yashar, Piotr A Domanski
Abstract: This paper presents a study of the air flow distribution through a residential air-conditioning heat exchanger. The test subject was a finned-tube, A-shaped coil outfitted with a condensation collection pan required for horizontal installation. We ...

33. Method to determine the absorbance of thin films for photovoltaic technology
Topic: Energy Conservation
Published: 6/20/2010
Authors: Nathan A Tomlin, John H Lehman, Katherine E. Hurst, D. B. Tanner, K. Kamaras, Aron Pekker
Abstract: We have demonstrated a novel method to determine optical properties of opaque or semi-transparent films for photovoltaic (PV) applications. Such films may be the basis of transparent conductors or photoconductive material. As an example, we measure t ...

35. Effect of Al2O3 Nanolubricant on R134a Pool Boiling Heat Transfer with Extensive Measurement and Analysis Details
Series: Technical Note (NIST TN)
Report Number: 1663
Topic: Energy Conservation
Published: 5/5/2010
Author: Mark A Kedzierski
Abstract: This paper quantifies the influence of Al2O3 nanoparticles on the pool boiling performance of R134a/polyolester mixtures on a roughened, horizontal, flat surface. Nanofluids are liquids that contain dispersed nano-size particles. A lubricant based ...

36. On the 60 mV/dec @300 K Limit for MOSFET Subthreshold Swing
Topic: Energy Conservation
Published: 4/26/2010
Author: Kin P Cheung
Abstract: The 60 mV/dec limit for subthreshold swing at 300K is generally considered a fundamental limit that cannot be defeated. The physical origin of this limit is revisited in this paper and the fact that this limit is in part determined by the density-ofs ...

37. Measurement Challenges in Achieving Energy Monitoring Systems in Buildings
Series: Technical Note (NIST TN)
Report Number: 1656
Topic: Energy Conservation
Published: 3/3/2010
Author: William M Healy
Abstract: The benefits of energy conserving approaches in buildings are often not apparent to building occupants because of the insufficient feedback provided regarding energy consumption. A review of the literature suggests that energy feedback devices can p ...

38. Life-Cycle Carbon and Cost Analysis of Energy Efficiency Measures in New Commercial Buildings
Topic: Energy Conservation
Published: 3/1/2010
Author: Joshua D Kneifel
Abstract: Building energy efficiency has become a top priority due to the recent energy price spikes and increasing concern regarding climate change. It is easier and less costly to increase energy efficiency in new buildings than in existing buildings, making ...

39. Micro Effects for Single Phase Pressure Drop In Microchannels
Topic: Energy Conservation
Published: 3/3/2008
Authors: Dong H. Han, Mark A Kedzierski
Abstract: This paper investigates the significance of several micro-effects that have been proposed to influence pressure drop measurements in microchannels. Pressure drop measurements were made for liquid flow within tubular microchannels nominally ranging i ...
