The characteristics of enzymatic/mild acidolysis lignin (EMAL) isolated from moso bamboo were investigated using pyrolysis-gas chromato-graphy/mass spectrometry (Py-GC/MS). Pyrolysis temperature as a factor on products was studied, and the pyrolysis mechanism was inferred with respect to the dominating products. Research…

Nanoparticles are widely used in the papermaking industry as retention/ drainage aids, usually in conjunction with a high mass cationic polyelectrolyte such as cationic starch. However, little convincing knowledge of their role and mechanism in the wet-end system is yet…

Background: During preoperative preparation patients undergo investigations to detect asymptomatic diseases. The probability of finding significant abnormalities on such "routine" investigations is small, unnecessarily increasing costs of perioperative care. We evaluated current practices, compliance with guidelines and costs of preoperative…
