    Microcalorimetric research on recombinant Escherichia coli with high production of polyhydroxyalkanoates (PHAs)

    The thermogenic curves of metabolism of the four strains of Escherichia coli pUC19cab/JM109, pUC19cab/XL-IBlue, JM109 and XL-IBlue were determined using the LKB-2277 BioActivity Monitor and the ampoule method at ...

    Direct observations of changes in surface structures by scanning tunneling microscopy

    Recently, we have studied the interaction of reactive adsorbates H, C, O, and S with Ni and Cu surfaces by scanning tunneling microscopy (STM). In this paper, we briefly illustrate and discuss how such studies...
