Molecular and Electrochemical Impedance Spectroscopic Characterization of the Carbopol Based Bigel and Its Application in Iontophoretic Delivery of Antimicrobials

open access: yesInternational Journal of Electrochemical Science, 2014
The current study describes development and characterization of carbopol based bigels for the iontophoretic delivery of antimicrobials. The bigels were prepared by mixing carbopol aquagel and sorbitan monostearate (SMS)-sesame oil based oleogels.

Determination of Some Soil Properties with Near-infrared Reflectance Spectroscopy

open access: yesJournal of Agricultural Sciences, 2012
At the modern soil classification system, it is necessary to determine the soil parameters, which cannot be identified in situ, under the laboratory conditions. The obtained data can be validated and interpreted by soil formation hypotheses.

Reflection spectroscopy of atherosclerotic plaque

open access: yesJournal of Biomedical Optics, 2006
Heart disease is the primary cause of death in the western world. Many of these deaths are caused by the rupture of vulnerable plaque. Vulnerable plaques are characterized by a large lipid core covered by a thin fibrous cap. One method for detecting these plaques is reflection spectroscopy.

Rotationally Resolved Spectroscopy of Asteroid Pairs: No Spectral Variation Suggests Fission is followed by Settling of Dust

open access: yes, 2014
We examine the spectral properties of asteroid pairs that were disrupted in the last 2 Myrs to examine whether the site of the fission can be revealed.
