Denitrification hotspots in riparian aquifers often develop in a relatively narrow zone at the upland-riparian interface, where nitrate-rich ground water of upland origin interacts with available soil organic carbon. In riparian paddy fields, denitrification in the aquifer has received less attention than that in the surface water and soil. This study aimed(More)
A novel amphiphilic vitamin C (VC) derivative, disodium isostearyl 2-O-L-ascorbyl phosphate (VCP-IS-2Na), which possesses a C(18) alkyl chain attached to a stable ascorbate derivative, sodium L-ascorbic acid 2-phosphate (VCP-Na), was evaluated as a topical prodrug of VC with transdermal activity in human living skin equivalent (LSE) models. The permeation(More)
