Biodegradability of bio‐based and synthetic hydrogels as sustainable soil amendments: A review Open
Superabsorbent polymers (SAPs), sometimes known as hydrogels, have been proposed as soil amendments to enhance soil water management. But the performance of SAPs as soil amendments depends on their stability in soil. Bio‐based SAPs have be…

The Impacts of Bio-Based and Synthetic Hydrogels on Soil Hydraulic Properties: A Review Open
Soil hydraulic properties are important for the movement and distribution of water in agricultural soils. The ability of plants to easily extract water from soil can be limited by the texture and structure of the soil, and types of soil am…

Laboratory Determination of the Impact of Incorporated Alkali Lignin-Based Hydrogel on Soil Hydraulic Conductivity Open
Superabsorbent polymers (hydrogels) have been studied for their ability to influence soil hydraulic conductivity because they can store and release water due to their swelling properties. However, concerns related to the increased use of s…

Transitioning Students into BAE from a Common First-Year Engineering Curriculum - A Work in Progress Open
In Fall 2016, a new First Year Experience (FYE) was implemented for all incoming engineering students at the University of Kentucky, resulting in a restructuring of our curriculum during the sophomore through senior years and eliminating t…

The Confounding Effects of Particle Size and Substrate Bulk Density on Phanerochaete chrysosporium Pretreatment of Panicum virgatum Open
Phanerochaete chrysosporium treatment is less effective as a biological pretreatment on feedstock with larger particle sizes. We hypothesized that the improved effectiveness of the pretreatment when smaller particle sizes are used may be d…

Switchgrass (<em>Panicum virgatum</em>) fermentation by <em>Clostridium thermocellum</em> and <em>Clostridium saccharoperbutylacetonicum</em> sequential culture in a continuous flow reactor Open
The study was conducted to evaluate fermentation by Clostridium thermocellum and C. saccharoperbutylacetonicum in a continuous-flow, high-solids reactor. Liquid medium was continuously flowed through switchgrass (2 mm particle size) at one…
