New, wide-range reference equations for the thermal conductivity of ethylene and propylene as a function of temperature and density are presented. The equations are based in part upon a body of experimental data that has been critically assessed for
Microbiologically influenced corrosion (MIC) of carbon steel infrastructure is an emerging cost issue for the ethanol fuel industry. One bacterial species found in ethanol fuel environments, Acetobacter aceti, can convert ethanol to the corrosive species

Algae have a variety of uses, including pharmaceutical and cosmetic products, and as a potential energy source in the form of biodiesel, bioethanol and biogas. To optimize the commercial production and use of algal biomass, production facilities have to be
In recent years microwave-induced combustion (MIC) has proven a robust sample preparation technique for difficult-to-digest samples containing high carbon content, especially for halogens and sulfur. NIST has applied the MIC methodology in combination with
Numerous mathematical tools intended to optimize rate constants employed in detailed kinetic models and make them consistent with experimental data have been reported in the literature. A typical methodology begins with the assignment of uncertainties in
The development of surrogate fuels with measured and predicted thermophysical properties similar to their authentic refinery stream counterparts is critical for the development of fuels from alternative feed-stocks and the optimization of engines to

Non-specific binding of cellulases to lignin has been implicated as a major factor in the loss of cellulase activity during biomass conversion to sugars. It is believed that this binding may strongly impact process economics through loss of enzyme

Biomass analysis methods are used to compare compositions of different lignocellulosic feedstocks, to measure component balance around unit operations, and to determine yields through biomass to biofuels processes. Four biomass reference materials (RMs)
A simple electrochemical process for submonolayer deposition of ultrathin catalytic iridum (Ir) films is demonstrated. The process enables effective utilization of one of natures rarest elements while different substrates facilitate the exploration of

N-dodecane (n-C12H26) is a straight chain alkane that forms an important constituent of surrogate blends for common aviation fuels such as JP8 and Jet-A. The current study investigates n-dodecane pyrolysis and oxidation kinetics in the intermediate
Materials and photoelectrode architectures that are highly efficient, extremely stable, and made from low cost materials are required for commercially viable photoelectrochemical (PEC) water-splitting technology. A key challenge is the heterogeneous nature
