Unleashing the potential of sweetpotato in Sub-Saharan Africa Current challenges and way forward
BACKGROUND According to the Food and Agriculture Organization (FAO) statistics annual sweetpotato production in Africa has increased moderately from 11.6 million tonnes in 2002 to 12.9 million tonnes… Expand

End-functional PLLA nanofibers were fabricated into mats of random or aligned fibers and functionalized post-spinning using metal-free "click chemistry" with the peptide Tyr-Ile-Gly-Ser-Arg (YIGSR).… Expand
Poly-3-hydroxyoctanoate P(3HO), a medium chain length polyhydroxyalkanoate homopolymer from Pseudomonas mendocina.
Pseudomonas mendocina was found to produce a unique homopolymer of poly(3-hydroxyoctanoate), P(3HO), rather than a copolymer, when grown on sodium octanoate as the sole carbon source. Although this… Expand
Ring-opening polymerization of an O-carboxyanhydride monomer derived from L-malic acid
The synthesis and ring-opening polymerization (ROP) of an O-carboxyanhydride (OCA) monomer derived from L-malic acid (L-malOCA) is reported. Application of 4-dimethylaminopyridine as catalyst led to… Expand
Influence of compatibilizing agent molecular structure on the mechanical properties of phosphate glass fiber‐reinforced PLA composites
Eight compatibilizing agents were studied to investigate their effect on the quality of the interface between a phosphate glass fiber and a poly(lactic acid) (PLA) matrix. After application of the… Expand
Organocatalytic synthesis and post-polymerization functionalization of propargyl-functional poly(carbonate)s
The synthesis of well-defined propargyl-functional poly(carbonate)s was achieved via the organocatalytic ring-opening polymerization of 5-methyl-5-propargyloxycarbonyl-1,3-dioxan-2-one (MPC) using… Expand
Effect of field multiplication generation on seed potato quality in Kenya.
The adoption of clean seed and new varieties can significantly help to close this ―yield gap‖ and boost on-farm productivity. This yield gap can be attributed to the use of low quality seed potatoes… Expand

This work describes the preparation of a new class of in situ-forming poly(carbonate)-graft-poly(ethylene glycol) hybrid hydrogels using 'thiol-ene' photoclick chemistry. Morphological study by… Expand
Interfacial properties of phosphate glass fibres/PLA composites: Effect of the end functionalities of oligomeric PLA coupling agents
Polylactic acid (PLA) oligomers as coupling agents have shown higher interfacial shear strength in phosphate based glass fibres/PLA composites. To influence bonding on the glass fibre surface, short… Expand
