Polyatomic projectiles of different types over a broad range of velocities have been used to bombard solid targets. Electron, ion and neutral secondary emissions were measured in experiments at low and high impact velocities. In both nuclear and elec

Lipids A are the hydrophobic domains of bacterial endotoxic lipopolysaccharides. Since they are responsible for most of the biological activities (both pathogenic and beneficial) of endotoxins, the characterization of their structure is crucial to th

Sarafotoxins (SRTXs) form a family of toxic and potent vasoconstrictor peptides of 21 amino acids and two disulfide bonds. They are present in the venom of the burrowing asp Atractaspis engaddensis. We have made two derivatives of the amino acid sequ

A very simple time of flight mass spectrometer has been used to measure mass spectra for the negative ions of organic compounds in the mass range up to 3000 u. Desorbed ions were obtained by applying a constant negative voltage to a flat metallic sur
