The Chemistry Eurobachelor

It is only three years since the Bologna Declaration was signed by 29 European ministers of education. This historic document launched the process of creating a „European higher education area”︁ by 2010. Now there are moves under way in a number of countries to revise the chemistry degree structures. The European Chemistry Thematic Network has defined a European BSc in chemistry which is presented here.     

From here to Bologna

The Bologna process promises to create a unified education system in 45 countries by 2010. Is this an achievable goal? Terry Mitchell looks at the ins and outs of Bologna.     

Long-term atmospheric deposition wet-dry fluxes. Critical loads exceedences in an urban area

The present work provides an overview of the most relevant results concerning a five years monitoring programme of wet and dry deposition (1995-1999) in the city of Bologna. The aim of this research is to get an overall picture of atmospheric pollutants deposition inventory in an urban territory and to allow an assessment of the vulnerability of the area by comparing actual fluxes of acidity and nutrient nitrogen with the respective "critical loads" associated to the territory, in the framework of the UNECE LRTAP (Long Range Transboundary Air Pollution Convention). This comparison, for the Bologna monitoring station, shows "exceedance classes" from 4 to 6 for acidity and from 1 to 5 for nutrient nitrogen, reflecting an urban-industrial context, though a trend in reducing occurs from 1995 to 1999. A water layer surface sampler (DAS-MTX sampler) was employed for "surrogate" dry deposition collection. The contribute of dry fraction to the total deposition fluxes appears to prevail on wet fraction for many pollutants (up to more than 90% for total calcium and alkalinity). A comparison with long term monitoring results from some stations in Italian territory, shows that the differences among chemical species deposition fluxes may be ascribed both to the long distance aerial transport of pollutants and to site characteristics.     

Deterministic and Monte Carlo codes for multiple scattering photon transport with arbitrary polarization states

The Boltzmann–Chandrasekhar vector equation is the best model known for describing the diffusion of incoherent photon beams with arbitrary polarization state. A brief comparison of the transport equations (scalar and vector) is presented. Then, the state-of-the-art of the transport codes developed at Bologna based on these models is described. Finally, the application of these codes is illustrated with examples.

Pyrolysis gas chromatography-mass spectrometry of natural resins used for artistic objects

Summary Eight resins used as protective layers for paintings, small sculptures, jewelries and artistic furniture, namely, Manila copal, colophony, Venice turpentine, elemi, shellac, dammar, sandarac and mastic were subjected to pyrolysis gas chromatography-mass spectrometry (PY-GC-MS). Significant mass spectral ions were monitored in each pyrogram. A table for identification of such resins based on the most significant ions in the mass spectra of the pyrolysis fragments is proposed. The results of PY-GC-MS analysis of a sample from the earth globe Giovanni Enriques, attributed to the Venetian geographer Vincenzo Coronelli (1650–1718) (Museo della Specola, Department of Astronomy, University of Bologna), are reported as an example of practical application of the method to a real artistic sample.     

Emergences of supramolecular chemistry: from supramolecular chemistry to supramolecular science

We describe the field of supramolecular chemistry as a consequence of the progress of chemistry from its premises to recent achievements. Supramolecular chemistry has been claimed to be an emergent field of research taking its roots in chemistry. According to the definitions of emergences related to hierarchy or more recently to scope, supramolecular chemistry is shown to have bottom-up or top-down emergences. The bottom-up emergence, directly related to hierarchy by definition, opens up the world of nanochemistry and nanomaterials while the top-down one, attributable to scope due to the implication of supramolecular chemistry in other fields of research, open the world of supramolecular biochemistry. Both emergences lead supramolecular chemistry to become a supramolecular science. Combining supramolecular chemistry with biology opens new direction in the study of life and it origin.     

Analytical Chemistry in Australia

Abstract

Analytical chemistry in Australia is alive, but its current development can be likened to that of a young and vigorous infant who needs assured supplies of food, a favourable environment and some sound guidance for growth and eventual maturity. That analytical chemistry exists in Australia and is healthy, has occurred despite the existence of most of the 19 universities in Australia! Sweden, with a population of 8.5 million, has 10 chairs in analytical chemistry in 5 main universities and analytical chemistry has been an acknowledged branch of chemistry at Swedish universities since 1960¹. Australia, with a population of 13.5 million and reasonably comparable standard of living and industrial development, has only one chair in analytical chemistry (at The University of New South Wales) in its 19 universities. However, 4 of the remaining universities (Newcastle, La Trobe, Tasmania and Queensland) have a strong interest in analytical chemistry, which is somewhat difficult to discern by the incorporation of analytical chemistry in either general chemistry or inorganic chemistry departments.     

化学教学新课堂：科学抗疫中的化学知识

As the break out of COVID-19 epidemic, the prevention and control work was consequently carried out. Chemistry plays an important role in the white war. The structure of mask contains the knowledge of interfacial chemistry. The material of mask encompasses the knowledge of polymer chemistry. Nucleic acid test and COVID-19 vaccine research need the knowledge of biological chemistry. The sanitizers involve the knowledge of inorganic and organic chemistry. The knowledge of physical chemistry takes effect in daily hand washing with soap. Each drug against COVID-19 virus was a complex organic compound. All the above things can be taken as appropriate examples in chemistry teaching to display the charm of chemistry. Meanwhile, these examples help students to realize that chemistry works as a vital part in our lives and therefore active their motivation to study chemistry well.

Teaching the integrated and modern perspectives of analytical chemistry

The present situation of analytical chemistry teaching within a chemistry curriculum is exemplified by the reformed chemistry curriculum in Germany. This approach is contrasted with teaching analytical chemistry within a novel curriculum in natural sciences termed 'applied science'. The latter curriculum ensures a superior education in chemistry, physics, biology, mathematics and information science, thus gaining an integrated perspective of analytical chemistry.

Activities to foster training in nuclear and radiochemistry from IACS,IAEA-Vienna

Summary Given the mismatch between supply of and demand for nuclear scientists, education in nuclear and radiochemistry has become a serious concern. The Nuclear and Radiochemistry in Chemistry Education (NRIChEd) Curriculum Project was undertaken to reintroduce the topics normally covered in a one-semester radiochemistry course into the traditional courses of a four-year chemistry major: general chemistry, organic chemistry, quantitative and instrumental analysis, and physical chemistry. NRIChEd uses a three-pronged approach that incorporates radiochemistry topics when related topics in the basic courses are covered, presents special topics of general interest as a vehicle for teaching nuclear and radiochemistry alongside traditional chemistry, and incorporates the use of non-licensed amounts of radioactive substances in demonstrations and student laboratory experiments. This approach seeks not only to reestablish nuclear science in the chemistry curriculum, but to use it as a tool for elucidating fundamental and applied aspects of chemistry as well. Moreover, because of its relevance in many academic areas, nuclear science enriches the chemistry curriculum by encouraging interdisciplinary thinking and problem solving.

What History Tells Us about the Distinct Nature of Chemistry

Attention to the history of chemistry can help us recognise the characteristics of chemistry that have helped to maintain it as a separate scientific discipline with a unique identity. Three such features are highlighted in this paper. First, chemistry has maintained a distinct type of theoretical thinking, independent from that of physics even in the era of quantum chemistry. Second, chemical research has always been shaped by its ineliminable practical relevance and usefulness. Third, the lived experience of chemistry, spanning the laboratory, the classroom and everyday life, is distinctive in its multidimensional sensuousness. Furthermore, I argue that the combination of these three features makes chemistry an exemplary science.
