Modification of Chinese Fir with Alkyl Ketene Dimer (AKD): Processing and Characterization
A process for the chemical modification of Chinese fir with alkyl ketene dimer (AKD) was studied. The hydrophobicity of the resulting products was evaluated by characterization of the equilibrium moisture content, water-surface contact angle, water absorption coefficient, and antiswelling efficiency. The results indicated that when 5% AKD solution was used, the modified wood generally showed go...
متن کاملSimple and Environmentally Friendly Fabrication of Superhydrophobic Alkyl Ketene Dimer Coated MALDI Concentration Plates
Here we present a method to manufacture peptide-concentrating MALDI-plates with alkyl ketene dimer (AKD) as a new superhydrophobic coating. The fabrication of the hydrophobic plates included application of AKD by airbrush, and negative contact printing to generate the concentration sites. Deposited sample droplets were contained within the prestructured sites, and self-adjusted onto the site if...
متن کاملStudies on alkyl-xanthine derivatives. II. Pharmacokinetic and pharmacodynamic studies of a new bronchodilator, 1-methyl-3-propylxanthine (MPX).
A new xanthine derivative bronchodilator, 1-methyl-3-propylxanthine (MPX), and 1-methyl-3-butylxanthine (MBX) were synthesized. We evaluated their relaxant effects on tracheal smooth muscle isolated from guinea pigs and pharmacokinetic characteristics in rats using 1,3-dimethylxanthine (theophylline, TPH) as the reference drug. Dose-dependent relaxant effects were observed in the concentration ...
متن کاملPhosphine-alkene ligand-mediated alkyl-alkyl and alkyl-halide elimination processes from palladium(II).
N-Diphenylphosphino-7-aza-benzobicyclo[2.2.1]hept-2-ene (2) behaves as a chelating phosphine-alkene ligand for Pd(0) and Pd(II), promoting direct alkyl-alkyl and indirect alkyl-halide reductive elimination reactions due to the stabilisation of the resulting bis(phosphine-alkene)Pd(0) complex.
متن کاملThermal Studies of Zn(II), Cd(II) and Hg(II) Complexes of Some N-Alkyl-N-Phenyl-Dithiocarbamates
The thermal decomposition of Zn(II), Cd(II) and Hg(II) complexes of N-ethyl-N-phenyl and N-butyl-N-phenyl dithiocarbamates have been studied using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The products of the decomposition, at two different temperatures, were further characterized by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy ...
