Shashlik calorimetry: a combined Shashlik + Preshower detector for LHC

Shashlik Calorimetry is a new technique which has been developed to read out the light from lead/scintillator sampling calorimeters, using wavelength shifters and optical fibres. The light yield is in excess of 10000 photons per GeV with fine lateral segmentation and minimum dead space. It is expected that such calorimeters can be buildt at relatively low cost. The first results on energy resolution and angular resolution, obtained in a non-projective prototype exposed to high energy electrons, are encouraging. Further research and development are essential before building a full scale projective detector

Stability and Application Properties of Surfactant-Free Cosmetic Emulsions: An Instrumental Approach to Evaluate Their Potential

Technological innovation in the cosmetic field must necessarily consider not only the safety and efficacy requirements but also the growing attention to environmental issues and the need for sensory pleasure during application to satisfy the consumers' expectations. This work aimed to formulate an oil-in-water fluid emulsion stabilized by the combination of organic and inorganic powders, namely Zea mays starch and zinc oxide associated at different ratios in presence of a polysaccharidic rheological modifier. After verifying the physical stability of the prototypes with a mechanical stress test in a centrifuge, the rheological analyses were conducted in continuous and oscillatory flow conditions, and the immersion/de-immersion test, conducted using a texture analyzer, allowed identifying the system with the viscoelastic characteristics and the parameters of textures, such as firmness, consistency, and adhesiveness, more suitable for the formulation of skin-care products with low viscosity and high spreadability. Finally, we studied the compatibility of the powders with sunscreen filters and pigments, to optimize the systems and assess their potential use in finished products
