Fig. 3From: Hydrating softwood and hardwood samples using pure and modified supercritical carbon dioxideA comparison of the wood samples NMC at 504 h (3 weeks) after different treatment conditions. Each point represents the overall mean from five independent sets of measurements ± one standard error of the mean. *Normalised moisture content is expressed here as the percentage change in mass due to water in respect to the oven dried mass of the wood sampleBack to article page
