Fluoride removal in a fixed bed packed with granular calcite
A fixed bed reactor filled with calcite particles (mean strokes diameter, 0.20 mm) was constructed and the reactor was used to treat synthetic wastewater containing HF, NaF, NH4F or Na2SiF6 underExpand
Cycloartane glycosides from Trichosanthes tricuspidata
Three new cycloartane glycosides, named cyclotricuspidosides A, B and C, were isolated from the leaf and stem parts of Trichosanthes tricuspidata and the structure was determined as 28,31-di- O -β- d -glucopyranosides. Expand
Microbial transformation of dehydropinguisenol by Aspergillus sp.
Two metabolites were obtained by microbial transformation of a furanosesquiterpene alcohol, dehydropinguisenol and lejeuneapingu Eisenol, using Aspergillus niger and As pergillus cellulosae using a possible pathway for the formation of these compounds is discussed here together with their antimicrobial activity against A. niger.

Herbertane-type sesquiterpenoids from the liverwort Herbertus sakuraii.
Seven herbertane-type sesquiterpenoids were isolated from the Japanese liverwort Herbertus sakuraii and their structures were elucidated by spectroscopic methods. Expand
Highly oxygenated sesquiterpenes from the liverwort Trocholejeunea sandvicensis.
Four pinguisane type sesquiterpenes were isolated from the liverwort Trocholejeunea scandvicensis, together with three aromatic compounds, one of which is lejeuneapinguisenone and a possible biosynthetic pathway to it was postulated. Expand
Continuous Catalytic Dehydrogenation of Decalin under Mild Conditions
In order to apply the organic liquid hydrides as hydrogen storage and mobile media, continuous hydrogen production from decalin under mild temperature conditions (210–280°C) was attempted by the useExpand
Kinetic studies of copper permeation through supported liquid membranes containing hydroxyoxime as a mobile carrier.
The process of copper permeation through hollow fiber type liquid membrane impregnated with β-hydroxybenzophemone oxime (LIX65N) has been studied. Porous support hollow fibers were made of twoExpand
