Process parameters affecting the delignification of eucalyptus kraft pulp with peroxyacetic acid [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2004 Various process parameters affecting eucalyptus kraft pulp delignification with peroxyacetic acid were investigated. The results showed that pH was an important factor. The delignification rate increased with increasing pH to the value of 6.

Advanced Materials, EarlyView.A colloid‐mediated electroless plating (CMEP) strategy is proposed to fabricate hierarchically porous, amorphous Fe‐doped NiWB electrocatalysts under ambient conditions. The in situ formation of Fe‐W‐O colloidal species guides the formation of robust, porous catalyst layers with excellent mass transfer and durability, sustaining 500 mA cm−2 for 2000 h,
