Visualization of moisturizer effects in stratum corneum in vitro using THz spectroscopic imaging
Abstract:
We use terahertz time-domain spectroscopic (THz-TDS) imaging for the evaluation of moisturizing-substances effects over stratum corneum (SC) samples. Excised SC of porcine skin is used as an in vitro skin model. We evaluate the interaction of SC samples with glycerine and lanolin, two substances commonly used in moisturizers. In order to do this, THz images of SC samples after deposition of the substances are scanned. The response of the SC samples to a commercial moisturizer is also analyzed. Our results show that THz imaging is capable of sensing the distinct interaction mechanisms of the substances with the SC samples. The occlusive nature of lanolin, the hyperosmotic behavior of glycerine, and the moisturizing effect of the commercial moisturizer can be observed using THz-TDS imaging.

Determination of Moisture Content in Soil
Demonstrating Author: Bradley Schmitz
Soils normally contain a finite amount of water, which can be expressed as the “soil moisture content.” This moisture exists within the pore spaces in between soil aggregates (inter-aggregate pore space) and within soil aggregates (intra-aggregate pore space) (Figure 1). Normally this pore space is occupied by air and/or water. If all the pores are occupied by air,...
