Rational Designs for Highly Proton-Conductive Metal−Organic Frameworks
A novel metal−organic framework (MOF), (NH4)2(adp)[Zn2(ox)3]·3H2O (1) was synthesized and its structure was determined. We propose three types of rational design to introduce... -
Estimation of Volatile Emissions During the Excavation of Soil or Waste
A model is presented for estimating transient air emissions of volatile chemicals during excavation into a zone of contaminated soil or waste. Using measured in situ parameters,... -
Roles of Acetone-Conditioning and Lipid in Sorption of Organic Contaminants
Sorption of phenanthrene and 1-naphthol by a peat soil (PS) and its humic acid fractions (HAs) and humin (HM) was examined. Both phenanthrene and 1-naphthol consistently had... -
