Excitonic effects from geometric order and disorder explain broadband optical absorption in eumelanin
geometric order disorder explain broadband optical absorption melanin
2014/9/24
Eumelanin is a ubiquitous biological pigment, and the origin of its broadband absorption spectrum has long been a topic of scientific debate. Here, we report a first-principles computational investiga...
Nonperturbative vibrational energy relaxation effects on vibrational line shapes
Nonperturbative vibrational energy relaxation vibrational line shapes
2014/9/24
A general formulation of nonperturbative quantum dynamics of solutes in a condensed phase is proposed to calculate linear and nonlinear vibrational line shapes. In the weak solute-solvent interaction ...
The in Vitro Effects of Dexamethasone on Sheep Lens Glucose-6-Phosphate Dehydrogenase
Sheep eye lens dexamethasone glucose-6-phosphate dehydrogenase
2010/4/21
Glucose-6-phosphate dehydrogenase (G6PD) enzyme was purified from sheep lenses, and the in vitro effects of dexamethasone on the enzyme's activity were investigated. Sheep lens glucose-6-phosphate deh...
Incorporation of EDTA for the Elimination of Metal Inhibitory Effects in an Amperometric Biosensor Based on Mushroom Tissue Polyphenol Oxidase
Incorporation of EDTA the Elimination of Metal Inhibitory Effects an Amperometric Biosensor Based Mushroom Tissue Polyphenol Oxidase
2010/6/27
Enzyme based biosensors are highly selective devices which rely on the specific binding of the target analyte (the substrate) to the active-site regions of the enzyme. The enzymatic reaction between m...
Effects of bath relaxation on dissipative two-state dynamics
bath relaxation dissipative two-state dynamics
2014/9/24
A formal solution to the two-state Liouville equations is used to derive quantum equations of motion for dissipative two-state systems without making the assumption of a harmonic bath. The first-order...
