Abstract
The present study focuses on the investigation of the successive pictorial phases of the wall painting which survives on the missing eastern part of the magnificent mosaic composition in the interior of Rotunda, Thessaloniki, Greece. Rotunda, a circular domed monumental building, was constructed in the early 4th century AD and it is included in the UNESCO World Heritage List. Characterization analysis was performed by means of microscopic, spectroscopic and crystallographic techniques, in order to identify the technological features of the wall painting and the materials used, to document the initial Byzantine pictorial phase -known from the archaeological research- along with the overpaintings attributed to the 19th and 20th centuries. In this framework, the collected samples were studied with optical microscopy, Fourier transform infrared micro-spectroscopy, scanning electron microscopy, X-ray diffractometry and X-ray photoelectron spectroscopy. Among the detected materials and pigments (including zinc oxide, barium sulfate, red lead, green earth, Prussian blue, emerald green, ultramarine and cuprite), the use of brass powder for false gilding purposes was detected, which is a material rarely used for mural applications.

MATERIALS SCIENCE & ENGINEERING. C, MATERIALS FOR BIOLOGICAL APPLICATIONS 2020; 110:110730. [PMID: 32204041 DOI: 10.1016/j.msec.2020.110730] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/01/2019] [Revised: 02/03/2020] [Accepted: 02/03/2020] [Indexed: 12/25/2022]
Abstract
The first part of the paper provides a comprehensive analysis of the features of electron beam formation of polymer coatings with the prolonged release of the drug compound using ciprofloxacin and clotrimazole as an example. The influence features of the low-energy electron beam on the molecular structure of medicinal chemical preparations have been established. The impossibility of producing the coatings based on medicinal compounds with a complex molecular structure (vancomycin, micafungin, etc.) by a low-energy electron beam has been justified. The second part of the paper introduces a fundamentally new vacuum method for the formation of the composite coatings based on antibiotics and antifungal drugs, accompanied by the prolonged release of the drug component. This method allows the formation of composite coatings based on medicinal compounds with a complex molecular structure. It is effective for modifying implants to prevent the risk of implant-associated infectious complications which are the result of the occurrence of mixed biofilms. The method can be used to form composite layers based on topical antitumor drugs for cancer control.
