Fig. 6From: Evaluation of chemical treatments on dimensional stabilization of archeological waterlogged hardwoods obtained from the Thang Long Imperial Citadel site, VietnamScanning electron microscopy images of waterlogged Dysoxylum sp. and Albizia sp. samples: a1, b1 untreated Dysoxylum sp. wood, a2, b2 Dysoxylum sp. treated with PEG, a3, b3 Dysoxylum sp. treated with trehalose, and a4, b4 Dysoxylum sp. treated with keratin, c1, d1 untreated Albizia sp. wood, c2, d2 Albizia sp. treated with PEG, c3, d3 Albizia sp. treated with trehalose, and c4, d4 Albizia sp. treated with keratin. For a1–a4 and c1–c4, the scale bars represent a distance of 100 µm; for b1–b4 and d1–d4, the scale bars represent 10 µmBack to article page
