Covert Channel in RTP Payload Using a Pointer in Sip Header

open access: yesCommunications, 2016
The paper addresses the issue of hiding data in the network flow. The authors discuss a new proposal of the steganographic approach in IP telephony: transmitting texts using the pointer in the SIP header by means of a data stream within the RTP protocol.

Synthesis and characterization of amphiphilic nitroxide 1,1,3,3–tetraethylisoindoline–2–oxyl–5–sodium sulfonate (TEIOSNa)

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The synthesis and characterization of an amphiphilic nitroxide to be used as a controlling agent in a nitroxide‐mediated living radical polymerization in aqueous dispersion media is presented. In the first stage of nitroxide synthesis (phthalimide protection), two reaction methods were employed: traditional and microwave.
