The title waterborne polyurethane( WPU) emulsion was prepared from isophorone diisocyanate( IPDI),dimethylol propionic acid( DMPA),soybean oil( SOY) and lactic acid( LA). The structure of epoxidized soybean oil( ESO)-lactic polyol was characterized. The morphology and stability of emulsion and hea...
This article critically discusses whether accumulation of lactic acid, or in reality lactate and/or hydrogen (H+) ions, is a major cause of skeletal muscle fatigue, i.e. decline of muscle force or power output leading to impaired exercise performance. There exists a long history of studies on...

The Inside Back Cover picture pictures a MoOx-modified Ru catalyst (Ru–MoOx catalyst) and illustrates how the hydrogenation reaction of L-lactic acid occurs over the Ru–MoOx catalyst in aqueous phase. A small amount of MoOx on Ru catalyst (Mo/Ru=1:16) significantly enhanced the activity ...
Much effort has been made to enhance the toughness of poly (lactic acid) (PLA) to broaden its possible range of usage in technical applications. In this work, the compatibility of PLA with a partly bio-based ethylene-propylene-diene-rubber (EPDM) through reactive extrusion was investigated. ...
