Most investigations of large amplitude oscillatory shear (LAOS) rheometry to date have presumed uniform shear. The study of structured materials would especially benefit from LAOS rheometry but require the use of the larger gaps and roughened surface

Airborne benzene concentrations were measured in a room with controlled air exchange during surface cleaning with two petroleum-based solvents (a paint thinner and an engine degreaser). The solvents were spiked with benzene to obtain target concentra

A physiologically-based pharmacokinetic (PBPK) model of benzene inhalation based on a recent mouse model was adapted to include bone marrow (target organ) and urinary bladder compartments. Empirical data on human liver microsomal protein levels and l

There is growing emphasis in the United States and Europe regarding the quantification of dermal exposures to chemical mixtures and other substances. In this paper, we determine the dermal flux of benzene in neat form, in organic solvents, and in aqu

An analysis was completed to assess the economic benefits of rheology modifiers because of reduced viscosity and yield stress of high-solids pretreated corn stover (PCS) suspensions in a biomass-to-ethanol conversion facility. A process design develo

Biomass slurries, such as dilute-acid pretreated corn stover (PCS), will be a common process stream in biorefineries designed to convert agricultural residues into biofuels such as ethanol. In this work, the advantages and disadvantages of several rh
