Phosphate-Based Treatments for Conservation of Stone
RILEM Technical Letters (2017) 2: 14‐19 DOI: http://dx.doi.org/10.21809/rilemtechlett.2017.34 Phosphate‐based treatments for conservation of stone Enrico Sassoni a* a Department of Civil, Chemical, Environmental and Materials Engineering, University of Bologna, Via Terracini 28, 40131, Bologna, Italy Received: 30 May 2017 / Accepted: 09 August 2017 / Published online: 9 October 2017 © The Author(s) 2017.

Abstract To overcome the limitations of currently available protectives and consolidants for carbonate stones (such as marble and limestone), in 2011 the use of calcium phosphate was proposed. The idea is forming calcium phosphates (ideally hydroxyapatite) as the reaction product between the substrate and an aqueous solution of a phosphate salt that the stone is treated with. In this paper, the studies aimed at identifying the best treatment conditions (in terms of nature and concentration of the phosphate precursor, solution pH, reaction time, ionic and organic additions) are first briefly summarized. Then, the efficacy of the phosphate treatment in protecting marble from dissolution in rain and restoring cohesion of weathered marble and limestone is discussed. Some recent studies on the use of the phosphate treatment on alternative substrates and some future steps for research on the topic are finally outlined. Keywords: Cultural heritage; Marble; Hydroxyapatite; Protection; Consolidation 1 Introduction improve mechanical properties, by providing a binding action between the stone grains. Organic products are A great part of cultural heritage objects (e.g. monuments, effective in improving mechanical properties, but again architectural decorations and statues) is made of carbonate they lack compatibility and durability. -

Uranium-Free X Solution
www.nature.com/scientificreports OPEN Uranium‑free X solution: a new generation contrast agent for biological samples ultrastructure Aldo Moscardini1,6, Sebastiano Di Pietro 2,6, Giovanni Signore3*, Paola Parlanti4, Melissa Santi5, Mauro Gemmi5 & Valentina Cappello5* Biological samples are mainly composed of elements with a low atomic number which show a relatively low electron scattering power. For Transmission Electron Microscopy analysis, biological samples are generally embedded in resins, which allow thin sectioning of the specimen. Embedding resins are also composed by light atoms, thus the contrast diference between the biological sample and the surrounding resin is minimal. Due to that reason in the last decades, several staining solutions and approaches, performed with heavy metal salts, have been developed with the purpose of enhancing both the intrinsic sample contrast and the diferences between the sample and resin. The best staining was achieved with the uranyl acetate (UA) solution, which has been the election method for the study of morphology in biological samples. More recently several alternatives for UA have been proposed to get rid of its radiogenic issues, but to date none of these solutions has achieved efciencies comparable to UA. In this work, we propose a diferent staining solution (X Solution or X SOL), characterized by lanthanide polyoxometalates (LnPOMs) as heavy atoms source, which could be used alternatively to UA in negative staining (NS), in en bloc staining, and post sectioning staining (PSS) of biological samples. Furthermore, we show an extensive chemical characterization of the LnPOM species present in the solution and the detailed work for its fnal formulation, which brought remarkable results, and even better performances than UA. -
Titration of Aspirin Tablets
Bellevue College | CHEM& 161 Titration of Aspirin Tablets In this lab, you will determine the percent purity of two commercially available aspiring tablets using an acid-base titration. In general, an acid and a base react to produce a salt and water by transferring a proton (H+): HA (aq) + NaOH (aq) H2O (l) + NaA (aq) (1) acid base salt The active ingredient in aspirin, and the chemical for which aspirin is the common name, is acetylsalicylic acid. To determine the amount of aspirin (acetylsalicylic acid) in a sample, the precise volume and concentration of the NaOH, and the overall reaction, must be known. The NaOH serves as a secondary standard, because its concentration can change over time. To find the precise concentration of the NaOH, it must be titrated against a primary standard, an acid that dissolves completely in water, has a high molar mass, that remains pure upon standing, and is not hygroscopic (tending to attract water from the air). Because sodium hydroxide is hygroscopic, it draws water from its surroundings. This mean one cannot simply weigh out a sample of sodium hydroxide, dissolve it in water, and determine the number of moles of sodium hydroxide present using the mass recorded, since any sample of sodium hydroxide is likely to be a mixture of sodium hydroxide and water. Thus, the most common way to determine the concentration of any sodium hydroxide solution is by titration. Determining the precise concentration of NaOH using a primary standard is called standardization. You will first standardize your NaOH solution, and then use it to analyze aspirin tablets for their aspirin content and purity. -

DNAZone Classroom Kit Classroom kits created by Carnegie Mellon University and the University of Pittsburgh The Center for Nucleic Acids Science and Technology Kit title What is the pH? Chemistry of Acids and Bases Appropriate grade level Upper high school, AP Chemistry The concept of acids and bases is an important topic in any introductory chemistry course. It is also a crucial part of standardized exams. Because acids and bases are so prevalent in real life applications, learning the concept through hands-on experiments will enhance a student’s understanding of these topics Abstract and evoke curiosity and interest. The teaching plan of this kit follows the PPP model, which, stands for presentation, practice and production. The included set of activities involves using pH indicators to characterize the acidity of common household items and to gain understanding of the importance of acids and bases in controlling homeostasis in biological systems.
