“…This was achieved by implementing tests in the lab or with instrumental techniques, on the solubility/dispersibility of pigments, water content, the metal content in the inks, and the paper chromatography. Stuckey and Eilks reported a solubility test on inks . Here, we focus on pigments, because they are the coloring agents that remain under the skin, and it is fundamental that they are insoluble in any solvent, because this gives indications of the stability upon injection, even when coming in contact with layers of the skin with different polarities .…”

“…It can be inhibited by metals in any kind of environment. , Since it is also present in tubers such as potatoes, a straightforward test can be devised to detect metals in tattoo inks. The version of the catalase assay on a potato slice was subsequently implemented at Purdue University and by Stuckey and Eilks . Visually, this corresponds to the observation of gas evolution when H 2 O 2 is poured onto a potato slice (Figure , see the top left panels Bef.…”

Chemistry through Tattoo Inks: A Multilevel Approach to a Practice on the Rise for Eliciting Interest in Chemical Education

Within the framework of a nationwide project to boost students' enrollment in scientific disciplines in Italy, a multilevel science project was designed with a focus on the chemistry of tattoo inks, offering immediate connection with 16−18 year-old high school students. The approach takes into account time constraints, since all sessions have a maximum span of 8 h, and the heterogeneity of the audience, made up of students without background restrictions. Tattoos are perceived as a form of body art and can be conveniently used as the "A" in the STEAM (science, technology, engineering, art, and mathematics) methodology. The project involved active lectures and guided inquiry into the simple chemical concepts related to tattoo inks, addressed in practical units with multioutcome experiments and comparative instrumental analysis. The connections with correlated issues, such as norms regarding tattoo ink composition and verification, were also discussed. The efficacy of the tattoo ink Scientific Degree Plan experience was then evaluated through two types of surveys: one on the enjoyment of the plan and the other on mastery of the chemical concepts at the end of the experience.

AbstraktPřírodovědná gramotnost je pojem, který je od 50. let 20. století užíván v mezinárodním prostředí, v posledních desetiletích v souvislosti s šetřením PISA. Také v kontextu vzdělávání v České republice se s tímto pojmem můžeme setkat, ačkoli neexistuje jeho jediné vymezení. Cílem studie je analýza a porovnání tří českých a jednoho mezinárodního dokumentu, které se k přírodovědné gramotnosti vztahují. Na základě obsahové analýz y a komparace dokumentů se ukazuje, že jednotlivá vymezení přírodovědné gramotnosti shodně zahrnují: znalost a používání přírodovědných pojmů; znalost a používání vědeckých metod; reflexi vědecké práce a širší kontext přírodovědného poznání. Vymezení se liší jen mírně, a to především v důrazu na životní prostředí, souvislost mezi rozvojem přírodovědné a čtenářské gramotnosti, zacházení s informacemi z médií a v různém detailu vymezení přírodovědné gramotnosti. Implementování přírodovědné gramotnosti do aktuálně revidovaného kurikula se jeví jako možné bez větších obtíží. Klíčová slova přírodovědná gramotnost, přírodovědné vzdělávání, kurikulum, kurikulární dokument, obsahová analýza, PISAAbstract Scientific literacy is a term which has been internationally used since the 1950s. In recent decades, the term has often been connected to the Programme for International Student Assessment (PISA). The term also appears in the context of the Czech educational system, though it has multiple definitions. The objective of this study is to analyze and compare four documents on scientific literacy (of which three are Czech and one international). Content analysis and comparison of the documents show that individual definitions of the term share the following features: knowledge and the use of scientific terms, knowledge and the use of the scientific methods, reflection of scientific work, and the broader context of scientific knowledge. The definitions differ 94 SVATAVA JANOUŠKOVÁ, VOJTĚCH ŽÁK, MARTIN RUSEK only slightly, mostly in their emphasis on the environment, the connections between the development of scientific and reading literacy, how they deal with information obtained from the media, and other minor details. The study concludes by showing that implementation of scientific literacy in the current revised curriculum seems to be possible without major difficulties.

Ionic Liquids as Extractor Agents and Reaction Media in Ester Synthesis

et al. 2015

During the last decade, ionic liquids technology has received growing attention due to the advantages they offer with respect to organic solvents. Although, in many cases, ionic liquids have simply been used to replace organic solvents, mainly due to their lack of vapor pressure, they have often led to improve process. In this work, the focus is on the application of ionic liquid technology as reaction media in the enzymatic synthesis of esters and also as extractor agents in the separation of reaction mixtures in the synthesis of esters. As reaction media, ionic liquids are opening up new fields in nonaqueous enzymology. The advantages of using ionic liquids over the use of organic solvents as reaction medium for biocatalysis include enhancement of enzyme activity, stability and selectivity. In this work, the effect of the nature of the ionic liquid on activity, selectivity, and stability of enzymes which catalyze esters synthesis has been carefully analyzed. The use of ionic liquids as extraction agent is also overviewed. Specifically, liquid‐liquid extraction using ionic liquids and supported liquid membranes based on ionic liquids have been studied.
