Fig. 1From: Multi-scale processes of beech wood disintegration and pretreatment with 1-ethyl-3-methylimidazolium acetate/water mixturesMorphology of beech chips pretreated in EMIMAc-water mixtures. The water mass fraction increases from left to right as indicated above the samples. While the material is completely disintegrated at low water content, it retains the original morphology at highest water contentBack to article page
