As we acknowledge that our sample fries all too quickly, we l also discuss low dose techniques and phase plates. Finally, we provide a short outlook towards exciting developments that may well push cryo-electron tomography

Electron tomography can also be performed on serial sections which allows entire cells or tissue volumes to be reconstructed at high resolution. Further, high precision correlative microscopy workflows can be implemented, permitting to combine information on mole

Richard Baskervilleum, this is achieved in two steps. First, the higher vapor pressure impurities (i.e., air components like N., O., CO., etc.) are condensed in a closed-cycle refrigerator-based purifier. Then, the lower vapor pressure impurities (mainly H.), which cannot be condensed in the cryogenic purifier, are el

Action Research and Design in Information Systemstween research and design. It then puts forward a simple philosophical framework that will be used to put in perspective the designerly ways of knowing, their relationship with action research, and the resulting implications on information systems research. The chapter closes with the re-examination
