He is working now with his research group at the Faculty of Chemistry, [[University of Bielefeld]]. == Academic career == Achim Müller studied chemistry and physics at the University of G&ouml;ttingen and received there his PhD degree (1965) and the Habilitation (1967). In 1971 he became professor at the University of Dortmund, and since 1977 he is professor of Inorganic Chemistry at the University of Bielefeld. His research involves the chemistry of transition metals in synthesis, spectroscopy, and theory with relation to nanochemistry in general, bioinorganic chemistry including biological nitrogen fixation, magnetochemistry, molecular physics and popularised science and natural philosophy. He has published, besides numerous original papers, more than 40 reviews and is coeditor of 14 books. Achim M&uuml;ller is a member of some leading academies (e.g. [[Academia Europaea]], [http://www.leopoldina-halle.de/e_index.htm Deutsche Akademie der Naturforscher Leopoldina]) and is recipient of numerous awards (honorary doctor degrees, -professorships and -memberships) and prizes (e.g. [[Alfred Stock Memorial Prize]], 2000, Prix Gay-Lussac/Humboldt 2001, Sir Geoffrey Wilkinson Prize, 2001) as well as named lectureships (e.g. Centenary Lectureship Award of the Royal Society of Chemistry 2008/9). == Research == [[Image:Guapo2.png|thumbnail|250px|Porous nanosized spherical polyoxomolybdate based capsule: the 20 pores with crown-ether function are filled with guanidinium cations/guests.]] His currently most compelling research relates to bottom-up pathways towards tailor-made porous nanoclusters and their use as versatile materials (systems that are now addressed in research worldwide), including: *multi-supramolecular chemistry on sphere surfaces *striking examples for a supramolecular/chemical Darwinism *modelling cation and counter cation transport through membranes *new solution states for inorganic ions through vesicle formation *coordination chemistry at the surface, in the pores and in the cavity of the nanocapsules *encapsulation chemistry in general *versatile linking in different phases: films, monolayers, liquid crystals *unprecedented molecular magnets. Müller's discovery of the molecular giant [[sphere]]s (keplerates) of the type Mo<sub>132</sub> (diameter ca. 3 nm), of the wheel shaped cluster Mo<sub>154</sub> and lemon shaped cluster Mo<sub>368</sub> (as large as 6 nm) has caused a paradigm shift not only regarding sizes of molecules but also their worldwide use as [[nanomaterials]]. These single [[molecules]] are quite large; this can be shown by taking the length of an [[oxygen]] molecule with two [[atom]]s (length 0.12 nm) as a meter, then to place Mo<sub>368</sub> which is 50 times as large. M&uuml;ller's recent work demonstrates how cellular processes like ion-transport can be modeled in relation to spherical oxomolybdate capsules. All these clusters belong to a class commonly known as [[polyoxometalate]]s and some special ones to the [[molybdenum blue]] family. == Publications == See either ISI Highly Cited Researchers or homepage (links below); for response to publications see homepage. == Personal == He likes ancient Greek philosophy, classical music and mountain hiking. He has a love for woodland birds since his early childhood, a pastime which had been cherished by his father. ==References== * Molecular growth from a Mo<sub>176</sub> to a Mo<sub>248</sub> cluster, A.
