Deoxyribonucleic Acid (DNA) has been recently found to be an efficient renewable and environmentally-friendly flame retardant. In this work, for the first time, we have used waste DNA from fishing industry to modify clay structure in order to increase the clay interactions with epoxy resin and take benefit of its additional thermal property effect on thermo-physical properties of epoxy-clay nan...
Hybrids of the model BSA protein and layered silicate clay with d spacing of approximately 62 A were prepared from either direct or stepwise intercalation. The pristine montmorilloinite (Na+-MMT) was first modified by poly(oxyalkylene)-amine salts (POP- and POE-amine) of 2000 g/mol Mw to a gallery-expanded silicate (d spacing=53 and 18 A, respectively), which became accessible for BSA protein e...
The multi-soil-layering (MSL) system primarily comprises two parts, specifically, the soil mixture layer (SML) and the permeable layer (PL). In Japan, zeolite is typically used as the permeable layer material. In the present study, zeolite was substituted with comparatively cheaper and more environmentally friendly materials, such as expanded clay aggregates, oyster shells, and already-used gra...
SUPERCRITICAL CARBON DIOXIDE PROCESSING OF NANO CLAYS ANDPOLYMER/CLAY NANOCOMPOSITESbyMIHAI MANITIUAugust 2010Advisor: Rangaramanujam KannanCo-Advisor: Esin GulariMajor: Chemical EngineeringDegree: Doctor of Philosophy Effective dispersion of the fillers in a polymer matrix and improvement of polymer clayinteractions are two key challenges in the field of...
Transport behavior of '37Cs in the environment is regulated by surface sorption reactions on clay mineral surfaces. To provide greater understanding of Cs transport processes, XAFS investigations of the local environments of 133Cs sorbed to clay minerals were conducted on Cs-Ca exchanged clay suspensions at the Cs LIII-edge. With decreased surface loadings of Cs, the Cs local environment exhibi...
activity of biohybrid coatings of atrazine-degrading bacteria Pseudomonas sp. ADP" (2014). The atrazine-degrading bacterial strain Pseudomonas sp. ADP was immobilized by the sol–gel process within thin silica layers coated onto water-retaining carrier materials (expanded clay pellets and scoria). The performance of the obtained biohybrid material has been investigated concerning long-term activ...
The present study was conducted to evaluate the effect of expanded clay (Leca) and Styrofoam on the physical characteristics of growing media and their relationship with the growth of Spathiphyllum wallisii. The experiment was laid out in a complete randomized design (CRD) with 9 treatments and 3 replications. Cocopeat and peat moss combined with different proportions of inorganic materials Lec...
