This work deals with the design of a highly sensitive whole cell-based biosensor for heavy metal detection in liquid medium. The biosensor is constituted of a Love wave sensor coated with a polyelectrolyte multilayer (PEM). Escherichia coli bacteria are used as bioreceptors as their viscoelastic properties are influenced by toxic heavy metals. The acoustic sensor is constituted of a quartz subs...

Restored prairies are expected to improve soil physical properties, yet little is known about the extent of change to soil properties and how rapidly these changes take place. The objective of this study was to compare effects of prairie restoration on computed tomography (CT)-measured pore parameters. Undisturbed soil cores (76 mm diam. by 76 mm long) from native prairie (NP), restored prairie...

Preventing enzyme deactivation while increasing their accessibility by adsorption in mesopores remains a key challenge the design of biocompatible supported enzymatic catalysts. Herein, it is expected that food-grade monomeric or polymeric glycopeptides containing organic phosphate groups (as casein phosphopeptide derivatives) enhances entrapment over one pot method wet precipitation calcium (C...

The synthesis of 2-amino-chromene with excellent yields (82%) was achieved by utilizing basic hierarchical zeolites prepared surfactant-templating as catalysts in a multicomponent reaction under solvent-free conditions. use these more than doubles the activity their microporous counterparts. These results highlight superior diffusivity and performance zeolites, which can be attributed to well-d...

Adsorption-induced deformation of monolithic, hierarchically organised porous carbon materials exhibiting non-convex mesoporosity between hexagonally arranged nanorods was investigated with adsorption dilatometry and small-angle neutron scattering (SANS). n-pentane zeroscattering length density used as an adsorbate for SANS. To assess the influence micropores on deformation, three samples diffe...
