Evaluation of the effectiveness of deep polymer impregnation as a corrosion abatement technique for overlaid bridge decks
… Mortar cubes were made, dried to different temperatures between room temperature and 600 °F, impregnated and polymerized. The cubes were then vacuum saturated and their resistivity obtained. They were then cut, dried to 220 °F and the effects of drying temperature was evaluated using a …

A novel system to study seed recalcitrance and dormancy - comparative proteomics between two Spartina species
… release by cold stratification and the effect of drying temperature on the critical water content. Comparative proteomics between S. alterniflora and orthodox, desiccation tolerant Spartina pectinata seeds identified 83 heat-stable (soluble after 40 min at 95oC) spots that were significantly more …

Development of All-Natural, Protein-Rich Snacks from imperfect Fruits and Vegetables
… often wasted due to spoilage and imperfections. Drying can extend the shelf life of produce and hide imperfections.Conventional drying methods like spray drying have high energy requirements and waste a portion of each fruit. Foam Mat Drying (FMD) has garnered renewed interest for the development …

Solution-casting of Disulfonated Poly(arylene ether sulfone) Multiblock Copolymer Films for Proton Exchange Membranes
… demonstrated that solvent selectivity and drying temperature as well as the block length had considerable effects on the final morphology and properties. The proton conductivity could be significantly increased by simply utilizing a selective solvent, dimethylacetamide (DMAC), which is good …

Single molecule tracking studies of solvent-swollen microdomains in cylinder-forming polystyrene-Poly (ethylene oxide) diblock copolymer films
… SRB molecules are measured at different drying times to assess the microdomain radius and permeability. These parameters, on average, gradually decrease with an increase in drying time; however the trend differs slightly from one solvent system to another. A sharp decrease of microdomain …

Comparative Analysis of Inactivated Wood Surfaces
A wood surface, which is exposed to a high temperature condition, can experience inactivation. Surface inactivation results in reduced ability of an adhesive to properly wet, flow, penetrate, and cure. Thus, an inactivated wood surface does not bond well with adhesives. The changes in surface …
