Spiral alumina nanowires, doped with Cr and Si, are directly and reliably produced in bulk quantities via annealing of high entropy alloys.
In this article, the development of a novel technique to fabricate spherical polymeric microcapsules by utilizing microfluidic technology is presented. Atom transfer radical polymerization (ATRP) was employed to synthesize well-defined amphiphilic block copolymers. An organic polymer solution was constrained to adopt the spherical droplets in a continuous water phase at a T-junction microchanne...
The aggregation of personal attributes into user profiles is a significant privacy concern. Existing attribute management systems support the controlled release of attributes and unlinkability between session protocols, but do not address the problem that attributes distributed in this way may be data-mined for features that allow user profiles to be reconstructed. This paper identifies the agg...
Introduction When transdermal drug delivery systems were first introduced clinically about 25 years ago, the purpose of controlled release technologies was the constant-rate, long-term release of active agents; a major objective of CR technologies was to develop dosage forms which, with one dose, release active agents at a constant rate effective over a long time period, There were two major un...
