Transmission electron microscopy has been used to examine carbon extracted from the Allende meteorite. The structure of the carbon is rather disordered, consisting of curved and faceted graphitic sheets which often enclose voids of the order of 2–1

Accelerators, capable of producing beams of ions up to several MeV are frequently used for (micro-)analytical purposes. In the majority of cases, the activities are centered around an accelerator previously exclusively used for studies in nuclear phy

Transmission electron microscopy has been used to examine carbon isolated from the Allende meteorite. The structure of the carbon is rather disordered, consisting of curved and faceted graphene sheets with little large scale graphitization, and resem

Covalent binding of chemicals or their metabolites to DNA is a critical event in the initiation of chemical carcinogenesis. Measurement of covalent DNA adducts in model and human systems has become an important tool in mutation and cancer research. T

Evidence was found that the inhibitory action of Cu(DMP)2NO3, the copper(I) complex of 2,9-dimethyl-1,10-phenanthroline (DMP), on Mycoplasma gallisepticum is a consequence of the ultimate toxicity of copper, and not that of the ligand, DMP. From upta
