More that just magnificent views of atoms and
molecules, Scanning Tunneling Microscopy, STM, images have
the potential to answer some fundamental questions relating
to surface molecular dynamics and bonding characteristics of
localized species versus more common analytical tools that
provide average of bulk sample information. A special
feature of the...
The mycosporins, formerly called P310's are secondary metabolites
of fungi closely associated with fungal reproductive processes that
require light. The structurally related iminomycosporins are found in
marine plants and animals and may also have functions related to
light. In this study, approaches toward the asymmetric synthesis of
the mycosporins are...
The effects of different nitrogen sources on the primary and secondary pathways of Azotobacter vinelandii cells were studied by means of the radiorespirometric method. C¹⁴ labeled glucose and several key amino acids related to the tricarboxylic acid cycle, such as glutamic acid, aspartic acid, alanine, serine and glycine were used...
Fluorinated alkyl substances, which can be persistent, toxic, and
bioaccumulative, have been quantitated in many densely populated and
remote regions, including in air, surface waters, groundwater, and biota;
however, little is known about their transport or behavior in the environment.
Wastewater effluent is one of the principal routes for introducing...
