چکیده

A novel method for in vitro calibration of skin hydration measurements is presented. The method combines gravimetric and electrical measurements and reveals an exponential dependency of measured electrical susceptance to absolute water content in the epidermal stratum corneum. The results also show that absorption of water into the stratum corneum exhibits three different phases with significant differences in absorption time constant. These phases probably correspond to bound, loosely bound, and bulk water.

Validation of a light-scattering PM2.5 sensor monitor based on the long-term gravimetric measurements in field tests

BACKGROUND Portable direct-reading instruments by light-scattering method are increasingly used in airborne fine particulate matter (PM2.5) monitoring. However, there are limited calibration studies on such instruments by applying the gravimetric method as reference method in field tests. METHODS An 8-month sampling was performed and 96 pairs of PM2.5 data by both the gravimetric method and t...

Preparation and Evaluation of Acyclovir Liposomes by Two Techniques: A Comparative Study

The aim of this study was to prepare liposomes of acyclovir (ACY) by thin layer evaporation (TLE) and reverse phase evaporation (REV) methods. Twenty-seven batches of liposomes from each method were prepared using technique of three variables at three levels (33) factorial design. Drug/Lipid (molar ratio), hydration volume and hydration time were considered three independent variables in TLE me...
