Fabrication and Characterization of Molybdenum Tips for Scanning Tunneling Microscopy and Spectroscopy

We present a method for the preparation of bulk molybdenum tips for scanning Tunneling Microscopy and Spectroscopy (STM - STS) and we assess their potential in performing high resolution imaging and local spectroscop by measurements on different single crystal surfaces in UHV, namely Au(111), Si(111)-7x7 and titanium oxide 2D ordered nanostructures supported on Au(111). The fabrication method is versatile and can be extended to other metals, e.g. cobalt

MICROBIOLOGICAL SURVEY ON JELLYFISH FOOD PRODUCTS: PRELIMINARY RESULTS

A microbiological survey was performed on ten brined jellyfish products, sampled in Italy from Chinese food markets. In general, the microbiological conditions were good and respected the standards contemplated in the regulations CE 2073/2005 e 1441/2007. The presence of inhibiting substances and the absence of aerobic mesophilic bacteria in two samples suggest a treatment to preserve the product
