The design and construction of two new sample injection systems or nozzles, for use with the Oregon State electron diffraction apparatus are discussed. One of these nozzles was intended for use with volatile samples the vapors of which were to be heated or cooled over the range -196 to 540°C;...
The furanyl diterpenoid family of natural products has drawn the attention of both synthetic organic chemists and pharmacologists due to their complex structural architectures and diverse biological activity. Among them, wortmannin has been most extensively studied for biological activities. All these furanyl diterpenoids consist of a highly strained naptha[1,8-bc]furan core,...
The structure–property relationships of solid solutions within the YbFe₂O₄ family of compounds have been studied in relation to their optical, dielectric and magnetic properties. This family of compounds is of recent interest because of the trigonal bipyramid coordination that is rarely observed in transition metal oxides. The systematic study of...

The use of an adjacency matrix to determine distant (not maximal or
minimal) subgroup and supergroup relationships between crystallographic spacegroup
types is described. Full lists of space-group types that are supergroups and
subgroups for every space-group type were compiled. A list of the space-group
types connected to each space-group type...
The atmospheric trace element abundances associated with "indoor"
and '"outdoor" air particulate have been measured for university chemistry
laboratories, typical homes, modern office buildings, hospital and
automobile repair garages in a rural setting (Corvallis, Oregon) and
modern office buildings in an urban setting (Portland, Oregon). Samples
of atmospheric particulate matter...
