UNLABELLED Accurate iris reproduction in the fabrication of ocular prosthesis in order to match the remaining eye is a key factor to mask the loss and achieve an esthetic outcome for anophthalmic patients. This study evaluated the stability of acrylic paints used for replicating iris color in ocular prostheses by the analysis of two factors: the temperature of the acrylic resin polymerization c...

BACKGROUND In view of the current epidemic of contact allergy to methylisothiazolinone (MI), it is important to clarify the extent of use of MI and related isothiazolinones in paints currently available for the consumer and worker in Europe. OBJECTIVES To elucidate the use and concentrations of MI, methylchloroisothiazolinone (MCI) and benzisothiazolinone (BIT) in paints on the European retai...

Worldwide prohibitions on lead gasoline additives were a major international public health accomplishment, the results of which are still being documented in parts of the world. Although the need to remove lead from paints has been recognized for over a century, evidence reported in this article indicates that lead-based paints for household use, some containing more than 10% lead, are readily ...

Biodeterioration in building façades represents an important economic loss related to maintaining a functional protective coating system. Research papers with long-time studies on paint performance exposed field conditions are scarce. Fungi, cyanobacteria, and algae frequently present biofilms formed outdoor locations. Among these, defacement caused by fungi is known for the broad damage spectr...

Abstract Green chemistry is the preferred approach for synthesis of metal and oxide nanoparticles due to its environmental friendliness, feasibility, safety human health when compared with other chemical or physical methods. Caesalpinia spinosa a promising resource be applied in green metallic high amount polyphenols. The aim present research was obtain an antifungal coating functionalised synt...

Fungal physical, chemical and aesthetical deterioration can occur by microbial biofilms adhere to the surface, leading alterations on paints integrity. The sol–gel method affords various merits added with biocides be used control paint films biodeterioration. aim of present research was obtain an efficient antifungal protection waterborne using a coating silver nanoparticles synthesized green m...

Two paintings, made on aluminium support by Silvio Pasotti (among the major exponents of 1960s Italian pop art) were investigated in a totally non-invasive manner to identify materials used artist. Raman spectroscopy, Fourier-transform infrared spectroscopy (FTIR), visible reflectance and spectrofluorimetry with excitation exploited as molecular analysis techniques, which are particularly suita...

In this paper, electrochemical behavior of epoxy paints embedded by modified calcium carbonate particles was investigated during exposure to 3.5 wt% NaCl solution. The precipitated calcium carbonate (PCC) and ground calcium carbonate (GCC) particles were utilized as inexpensive filler for epoxy paints. Electrochemical impedance spectroscopy (EIS), polarization tests and pin-on-disk method w...

In this study, simultaneous monitoring of indoor and outdoor Volatile Organic Compounds (VOCs) was carried out in a school, by both Radiello® cartridges real-time monitors (Corvus, IonScience Ltd., Fowlmere UK). Moreover, an air quality assessment performed with data from station (ARPA Puglia) located close to the school. particular, VOCs, Benzene, Toluene, Ethylbenzene, Xilenes concentrations,...
