Evaluation of Urea Encapsulation by Microcapsules of PHB/MMT and PHB/OMMT Nanocomposites

2018
Urea is the most used nitrogen fertilizer around the world being responsible for many environmental problems. Preparation of microcapsules from biodegradable polymer has been reported as a main system to sustain active substances, finding application in different areas.

A convenient route to PHB macromonomers via anionically controlled moderate‐temperature degradation of PHB

Journal of Polymer Science Part A: Polymer Chemistry, 2010
AbstractThe degradation of poly(3‐hydroxybutyrate)s in homo‐ and heterogeneous mixtures with selected salts of organic and mineral acids was investigated. Nonvolatile degradation products, of processes conducted at moderate temperatures (150–170 °C), were analyzed using 1H NMR.

Spherulitic Growth Rate of Blends of Polyhydroxybutyrate (PHB) with Oligomeric Atactic PHB-diol

Journal of Macromolecular Science, Part B, 2011
Spherulitic growth rates of blends of polyhydroxybutyrate (PHB) with oligomers of atactic R,S-PHB-OH (Mn = 610, 910, and 2670 g/mol), as well as atactic R,S-PHB (Mn = 30 000 g/mol), were investigated by polarized light optical microscopy in the range from 50°C to 110°C.

Mapping UMTS Bearers to DiffServ PHBs

2003
In this paper we address how the 3GPP-defined end-to-end QoS bearer services (conversational, streaming, interactive and background) for UMTS can be mapped to the IETF-defined Differentiated Services (Diff-Serv) per hop behaviours (Expedited Forwarding (EF), Assured Forwarding (AF) and Best Effort (BE)).
