We are also in the and most certainly strengthen our center. consortium combines cutting-edge To further emphasize that PCC is renewed knowledge of forest biomass chemistry, forefront of building new research and stronger than ever, the board also analytical chemistry, organic chemistry, projects around biomass refining and inorganic chemistry, and catalysis and new biomaterials together with VTT, decided to change the name to “Johan reaction engineering.

I believe these kinds Board hemicelluloses and lignin to a range of new chemicals and materials. Although our research plan is fresh and new, the original PCC concept stating that the development of new technologies should be based on a very deep understanding of the underlying chemical and physical processes, which we call Molecular Process Technology, still prevails. The statistics clearly show that the scientific output of PCC, especially the number of PhD's and peer-review articles, has continued to grow each year and I believe we are by far one of the strongest centers within our field in Finland and even globally. We also benefit greatly from our Johan Gadolin Scholarship Programme, established in 2007, which continues to provide us with excellent young and also more Prof. Stefan Willför Future Refining of Forest Biomass – the Molecular Process Technology Approach The Johan Gadolin Process Chemistry Centre (PCC) is now one of the centra of excellence in scientific research at Åbo Akademi.

The epoxidation process can be considerably enhanced by applying microwaves (MW) instead of conventional heating (CH). The experiments were conducted in a unique microwave reactor system constructed in collaboration with INSA Rouen. Polysaccharides Functional biopolymers (Water insoluble) (Water soluble) Electrochemical modification of polysaccharides A new reaction pathway has been found for modification of polysaccharides (e.g. cellulose and OH- hemicelluloses) giving the possibilities for novel and innovative utilization of Electro-catalytic oxidation Hydroxyl group cellulosic biomass. Polysaccharides can directly be converted into functional materials by electro-catalytic oxidation at an electrode surface. Au electrode Oxidized group Hemicellulose-based hydrogels New hydrogels based on hemicelluloses were prepared and utilized for toxic ion removal from aqueous solutions. The properties of the hydrogels can be tailored resulting in a sustainable material for wastewater treatment. Determination of gaseous sulfuric acid A completely new method for measuring low concentrations of gaseous sulfuric acid in flue gases was developed. This method is based on the reaction between a salt (KCl) and sulfuric acid. The method has been used in several industrial combustors in Finland and USA to study the risk of sulfuric acid induced low temperature corrosion and to maximize the energy recovery from the flue gases.

  • YTTRIUM Element Symbol: Y Atomic Number: 39
    YTTRIUM Element Symbol: Y Atomic Number: 39 An initiative of IYC 2011 brought to you by the RACI BRETT LITTLETON www.raci.org.au YTTRIUM Element symbol: Y Atomic number: 39 Yttrium is a soft, silver-metallic, lustrous and highly crystalline transition metal in group three. The tale of its discovery is quite interesting, involving several individuals. Lt. Carl Axel Arrhenius (1757–1824), born in Stockholm, served as a lieutenant at the Svea artilleriregemente stationed in Vaxholm; taking part in the campaign in Finland in 1788. During his time in Vaxholm he visited the feldspar mine in Ytterby. He found a dark mineral which he named ytterbite after the nearby village. After Arrhenius gave a sample of the new mineral to Johan Gadolin (1760–1852), a Finnish chemist and Mineralogist, Godolin subsequently discovered the oxide of yttrium in Arrhenius’ sample in 1789. Anders Gustaf Ekeberg (1767–1813), a Swedish chemist, confirmed Gadolin’s analysis, naming the new oxide yttria. Ytriium is relatively abundant in the earth’s crust; being the 28th most common element therein, and 400 times more common than silver. Interestingly, lunar rock samples collected during the Apollo program have unexpectedly high yttrium content. The most important use of yttrium is in making phosphors, such as the red phosphors used in television cathode ray tube displays and in LEDs. Other uses include the production of electrodes, electrolytes, electronic filters, lasers and superconductors. The radioactive isotope yttrium-90 is used in a range of different drugs, for the treatment of cancers, including lymphoma, leukemia and bone cancers. Provided by the element sponsor sponsor Phillips Ormonde Fitzpatrick ARTISTS DESCRIPTION Yttrium is used in making phospors, such as the red phosphors used in TV cathode ray tubes and in LEDS.

  • Jac. Berzelius and the Emerging Modern Chemistry
    Jac. Berzelius and the emerging modern chemistry By SIGVARD STRANDH Every year since 1956 the Swedish Society of chemists in cooperation with the Tekniska Museet has arranged ”Berzelius’s Memorial Lectures” to which every time about hundred young people from schools and colleges in all parts of the country are invited to hear lectures on Chemical problems of current interest. On January 2, 1970, Mr. Sigvard Strandh, Director of the Museum, presented his youthful audience the following picture of the famous Swedish chemist after whom the Lectures have got their name. Jac. Berzelius and the emerging modern chemistry Jöns Jacob Berzelius was born in 1779, a year after the death of Youth — in the tradition of Linnaeus Linnaeus, the great Swedish botanist, and his life was destined to be associated with Linnaeus in many other ways than merely by virtue of this succession in years. By the time Jacob Berzelius reached the end of his life in 1848 tokens of honour had been bestowed upon him by academies and learned societies from all over the world. Even during the course of his career his achievements had been compared with those of the celebrated Linnaeus and when the monument of Berzelius was un- veiled in the Stockholm park, which now is named after him, the customary poem of homage included the following stanzas: Hidden jorces of the Nature stones, water, plants and beasts, all you brought into good order, studied, weighed and well defined Learn us find the ways of Nature, seek the soul of slag and grass, feeling grief at having lost you, ever proud of Linné and you.

  • The Hidden History of Phlogiston: How Philosophical Failure
    The Hidden History of Phlogiston How Philosophical Failure Can Generate Historiographical Refinement Hasok Chang Abstract: Historians often feel that standard philosophical doctrines about the nature and development of science are not adequate for representing the real history of science. However, when philosophers of science fail to make sense of certain historical events, it is also possible that there is something wrong with the standard historical descriptions of those events, precluding any sensi- ble explanation. If so, philosophical failure can be useful as a guide for improv- ing historiography, and this constitutes a significant mode of productive inter- action between the history and the philosophy of science. I illustrate this methodological claim through the case of the Chemical Revolution. I argue that no standard philosophical theory of scientific method can explain why European chemists made a sudden and nearly unanimous switch of allegiance from the phlogiston theory to Lavoisier’s theory. A careful re-examination of the history reveals that the shift was neither so quick nor so unanimous as imagined even by many historians. In closing I offer brief reflections on how best to explain the general drift toward Lavoisier’s theory that did take place. Keywords: Chemical Revolution, phlogiston, history and philosophy of science, scientific change, Lavoisier. 1. Introduction Many historians of science have felt for some time that standard philosophi- cal doctrines about the nature and development of science are not adequate for representing the real history of science. This is one of the major obstacles standing in the way of productive collaboration between historians and phi- losophers of science.
