Thermochemical behavior of Chlorella sp. and Chlamydomonas reinhardtii algae: Comparison of laser-driven calorimetry with thermogravimetric analysis

May 12, 2021
Author(s)
Cary Presser, Ofra Paz Tal, Tsion Ohaion-Raz, Ana Lerner, Avihai Danon, Barak Dabush, Hadar Dubkin, Ashot Nazarian
A major focus of algal biofuel research is on maximizing the formation of the energy-containing compounds (i.e., carbohydrates, proteins, fatty acids, and lipids) during algal growth. Measurements were carried out to investigate the thermochemical

Simultaneous Transmission and Absorption Photometry of particle-laden filters from Wildland Fires during the Biomass Burning Observation Project (BBOP) field campaign

June 20, 2020
Author(s)
Cary Presser, Ashot Nazarian, Duli Chand, Arthur Sedlacek, John Hubbe
Transmissivity and absorptivity measurements were carried out simultaneously in the visible (wavelength of 532 nm) at laboratory conditions using particle-laden filters obtained from a three-wavelength particle/soot absorption photometer (PSAP). The

Laser-Driven Calorimetry Measurements of Petroleum and Biodiesel Fuels

September 20, 2017
Author(s)
Cary Presser, Ashot Nazarian, Amit Millo
The thermochemical characteristics were determined for several National Institute of Standards and Technology Standard Reference Material petroleum-based and biodiesel fuels, using a novel laser-heating calorimetry technique. Measurements focused on the

Laser-Driven Calorimetry of Single-Component Liquid Hydrocarbons

June 12, 2017
Author(s)
Cary Presser, Ashot Nazarian
A novel laser-heating technique, referred to as the laser-driven thermal reactor (LDTR), was used to determine sample thermal behavior, specific heat release rate, and total specific heat release of three volatile single-component liquid hydrocarbons, i.e

Thermochemical Characterization of Biodiesel Fuels using a Novel Laser-Heating Technique

August 4, 2015
Author(s)
Cary Presser, Ashot Nazarian, Thomas J. Bruno, Jacolin A. Murray, John L. Molloy
A state-of-the-art, rapid laser-heating technique, referred to as the laser-driven thermal reactor, was used to characterize National Institute of Standards and Technology Standard Reference Material (SRM) diesel and biodiesel fuels. Also described are the

Filter Material Effects on Particle Absorption Characteristics

February 10, 2014
Author(s)
Cary Presser, Joseph M. Conny, Ashot Nazarian
The absorption coefficient and mass specific absorption cross section were determined for nigrosin-laden quartz, Teflon, and polycarbonate filters in inert surroundings at different steady-state temperatures and particle mass loadings. The objective was to
