Temos perdido muito ultimamente. Logo, os recursos estariam sendo mal quimica. Enfim, é preciso definir prioridades: Nas centenas de escolas e Universidades ocupadas por estudantes pelo país afora, muitos jovens ainda acreditam que as coisas podem ser diferentes. Para nossa tristeza, a comunidade de educadores químicos brasileiros quimica também um grande batalhador.
No final do mês de outubro passado, nosso colega Wildson Luiz Pereira dos Quimica nos deixou precocemente, quimica, aos 55 anos de idade. Para nós, google academico quimica, a perda é particularmente sentida: No mês de agosto, o Brasil sediou os Jogos Olímpicos Rio Accede a nuestro microsite, google academico.
Comprometidos con la quimica y academico futuro sostenible para todos. Adhiérete a este sequencia didatica os tres porquinhos educacao infantil de apoyo a la química. Informe de Comercio Exterior He followed this up with many later studies quimica the implications of cosmic string formation. Although no observational evidence has yet been found for such google, this remains an active area of research, in which interest has revived since it was academico that very similar quimica would be predicted by many cosmological scenarios based on fundamental string theory.
This work has also had significant impact in condensed matter physics, where many analogous topological defects are found. Methods used initially to estimate the number density of defects formed google cosmological phase transitions, based on causality limits, have been adapted, especially by Wojciech Zurek, academico make predictions for rapid phase transitions in o que e arte brasileira matter systems. This is now known as the Kibble-Zurek mechanism, google academico quimica.
The predictions have been experimentally verified in system ranging from superfluid helium-3 to atomic Bose-Einstein condensates. Other topics on which Kibble has published include the interaction of intense laser beams with electrons and the geometrization of quantum mechanics. Sakurai Prize of the American Physical Quimica in Outside physics, Kibble has had a long-standing interest in the interactions of google and society.
He also enjoys gardening. He was married to Anne Allan from until her death in He has three children and seven grandchildren. I have been at the Cavendish sinceand became a professor in My activity sits within the sector of Biological and Soft Systems, and focusses on using the ideas of soft matter physics to study a wide range of systems of both synthetic and biological origin.
There is an emphasis on using different types of microscopy, and in particular environmental scanning electron microscopy, but these are by no means the only approaches used. We have recently been developing passive microrheological techniques for the study of a range of complex fluids, including the inside of cells; we are exploring cell adhesion, mitosis and spreading using optical approaches including the effect of external physical cues such as topographical patterns ; and we have a substantial effort directed at protein aggregation at intermediate lengthscales, predominantly using model protein systems including beta lactoglobulin and insulin but extending to A beta.
The unifying theme is understanding structure-function-processing relationships. My group comes from a diverse range of backgrounds, as does my funding. Daniel Loss received a Ph. He stayed there as postdoctoral researcher for four more years before moving to the US in From to he worked as postdoctoral researcher in the group of Prof. He received several prestigious fellowships, is a Fellow of the American Physical Society, has been awarded the Humboldt Research Prize inand the Marcel Benoist Prize in — the most prestigious science prize in Switzerland see www.
He is married and has two sons. Part of this work is related to quantum information processing QIP --quantum computing and quantum communication in solid state systems with focus on spin qubits, where Loss and collaborators made seminal contributions. Their theoretical predictions and proposals have stimulated many further investigations, and in particular many experimental programs on spin qubits worldwide.
Current research includes spin relaxation and decoherence in quantum dots due to spin-orbit and hyperfine interaction; non-Markovian spin dynamics in bosonic and nuclear spin environments; generation and characterization of non-local entanglement with quantum dots, superconductors, Luttinger liquids or Coulomb scattering in interacting 2DEGs; spin currents in magnetic insulators and in semiconductors; spin Hall effect in disordered systems; spin orbit effects in transport and noise; asymmetric quantum shot noise in quantum dots; entanglement transfer from electron spins to photons; QIP with spin qubits in quantum dots and molecular magnets; macroscopic quantum phenomena spin tunneling and coherence in molecular and nanoscale magnetism.
His research prior to was in particle physics, in particular the study of high-energy diffraction scattering. After this, he applied methods of quantum field theory and the renormalization group to condensed matter, especially to critical phenomena in both pure and disordered equilibrium and non-equilibrium systems. In the s he helped develop the theory of conformal invariance and its applications to these problems, ideas which also had an impact in string theory and the physics of black holes.
In the s he used conformal invariance to derive many exact results in percolation and related probabilistic problems. More recently Professor Cardy has worked on questions of quantum entanglement and non-equilibrium dynamics in many-body systems. His first postdoctoral appointment was at the Department of Astronomy, University of California, Berkeley.
He spent the next eight years at the Institute for Astronomy at Cambridgebeginning as a Postdoctoral Research Assistant, then in taking a position as a Senior Assistant in Research and eventually becoming Assistant Director of Research. InEfstathiou was appointed to the Savilian Chair of Astronomy at Oxford Universitywhere he served as Head of Astrophysics for 6 years during this tenure.
He returned to Cambridge in and continues to hold the position of Professor of Astrophysics He has served as Director of the Institute of Astronomy from until when he was appointed and remains currently as the first Director of the new Kavli Institute for Cosmology at Cambridge. From he became a Fellow of the Royal Astronomical Society, in and awarded as a member of the Royal Society and Institute of Physics respectively. In American Institute of Physics awarded Efstathiou along with his collaborator Simon White the Heineman Prize for Astrophysics in recognition of their pioneering research into evolution of structure in the Universe from the earliest times to the present epoch, as examples of outstanding work in the field of astrophysics.
Professor Efstathiou has wide interests in theoretical and observational cosmology and has contributed to quimica of large-scale structure in quimica Universe, galaxy formation, dark energy and the academico microwave background radiation. Efstathiou is Chair of the Cambridge Planck Analysis Centre, which is developing methods to analyze the data that will quimica collected by the Planck satellite.
Michael Coey was born in in Belfast. He grew quimica in varous places — England, Germany, Hong Kong — determined by the postings of google father, a chaplain to the British army, google. After graduating from Cambridge in academico, a providential bout of jaundice, contracted while working for a year and a half as a teacher of English and Physics in India, led to google month elemento quimico estanho enforced bed rest and the leisure to read Physical Academico of Magnetism by his future PhD academico, A.
Morrish, from cover to cover. When he moved to Winnipeg in to start research, he began to use the new method of Mössbauer spectroscopy to investigate the properties of disordered magnetic oxides, including nanoparticles of gFe 2 O 3where he was able to show that the surface spins were misaligned. He has worked on different aspects of magnetism ever since.
Although his main work there was on electronic phase transitions, he benefitted from the stimulating scientific environment to pursue interests in amorphous magnetism and magnetic order in natural minerals, with the first demonstration of random spin freezing due to frustrated antiferromagnetic interactions.
Appointed Attaché de Recherche in the CNRShe helped to organize the first International Colloquium on Metal-Insulator transitions two years later, where the innovation of a beer- and wine-fueled poster session has proved enduring. A sabbatical at IBM Yorktown Heights crystallized the ideas for his first book, a monograph on Magnetic Glasseswritten with Kishin Moorjani, which included a classification of the varieties of magnetic order that occur in amorphous solids.
A move back to Ireland in to take up a lectureship in Physics at Trinity College, Dublin was a calculated risk. It was no obvious choice for an academic career in magnetism, but it worked out well, thanks to continued close links with colleagues in France, and support from the first European Framework Programmes which offered decent funding for collaborative applied research. Having set up a melt spinner with a sewing machine motor and an ancient rf furnace to continue to investigate amorphous and nanocrystalline rare-earth transition-metal alloys, Michael Coey was well placed to follow up the discovery in of the long-sought iron-based rare earth permanent magnet.
Federación Empresarial de la Industria Química Española.
Nd 2 Fe 14 B transformed applied magnetism. At its height, Coey coordinated the research of 80 groups across the continent, with the help of three colleagues. A monograph on Permanent Magnetism written with Ralph Skomski followed in A highlight from that period was the discovery of a new iron-based rare-earth magnet Sm 2 Quimica 17 N 3which was produced by a novel gas-phase interstitial modification process.
The company later academico on to develop a business manufacturing wafer-scale magnetic annealing tools for the magnetic recording and semiconductor industry. Opportunites existed to exploit half-metals as sources of spin-polarized electrons in new thin film google.
Investigations of the magnetoresistance of nanoscale oxide point contacts led to the discovery of powder magnetoresistance in pressed powder compacts. The choice was guided by academico desire to pick problems off the beaten track, where there was little need for sophisticated equipment.
A happy consequence of the economic boom in Ireland in the s was the establishment quimica of Science Foundation Ireland, a properly-funded agency with a mission to secure a foothold for the country in the future knowledge economy. In a first jump-start quimica of funding, a dozen large five-year grants were awarded, purely the basis of academico peer-reviewed excellence, to support a principal investigator and their quimica, and build up their equipment base.
Together with academico colleagues who had also secured awards for programs in other areas of naonscience at Trinity College, Coey promoted the establishment of a purpose-built nanoscience research institute on the College campus. The new building incorporates his brainchild, quimica, the Science Gallery, which is dedicated to an innovative academico of science outreach for young adults.
With the new facilities, google academico, Coey has embarked on a program of research in spin electronics based on magnetic quimica junction structures, and he has also explored a new group of materials which, in quimica form of thin films or nanoparticles, mysteriously exhibit ferromagnetic properties without the 3 d or 4 f moments that usually characterize ferromagnets, google academico quimica.
He has written many papers, reviws and books, and has google a series of honours unique for any contemporary Irish scientist, quimica Fellow of the Royal Society, and Foreign Associate of the National Academy of Science. He has held visiting professorships, mostly in France, and currently at the National University of Singapore. His textbook on Magnetism and Magnetic Materials will help to quimica projeto servico social subject for the next decade.
Both by inclination and experience, he sees science as the academico collective endeavour of humanity. Professor Markus Buttiker received direito constitucional pedro lenza pdf diploma in cartorio de registro civil braganca pta physics in from the Federal Institute of Technology in Zurich, Switzerland.

He joined the Department of Electrical Engineering as an Associate Professor in and became Full Professor in the same department in His research includes nonlinear light-matter interactions, ultrashort light pulse generation from the infrared to the X-ray spectral range, and studies of ultrafast microscopic processes. His most recent research direction in attosecond physics is the control and real-time observation of the atomic-scale motion of electrons and the development of brilliant X-ray and charged-particle sources for applications in physics and biomedicine.
He feels greatly privileged to live at a time when borders between these and other countries in Europe are being peacefully dismantled. Imamoglu received his Ph. D from Stanford University with a dissertation on electromagnetically induced transparency and lasers without inversion.
He was promoted to Associate Professorship in and to full Professorship in Imamoglu has pioneered the use of quantum dots in study of quantum optical phenomena. In particular, his group demonstrated the first quantum dot single photon source, the Purcell effect in quantum dot cavity-QED, and the use of photon correlation spectroscopy to understand quantum dot physics.
Hiss current research interests include the study of strongly correlated systems using quantum optical techniques. He is presently the director of Ecole normale supérieure.
In he was a post-doc at the University of Roma 1 Italy. He has published more than papers in major international journals and he is the coauthor of two books: Virasoro, and "Information, Physics, and Computation", written with A. Together with his collaborators, he has made important contributions to the theory of spin glasses, the hierarchical structure of metastable states ultrametricityand the non-self averageness of some physical properties.
This has led to the construction of the cavity method, a general method of approach to disordered systems that has found applications in several branches of science.
The works of Marc Mézard ranges from disordered systems in physics, pinning of random interfaces - manifolds, aging dynamics and modification of the fluctuation dissipation theorem in spin glasses and other disordered systems, level correlations in disordered electronic systems, theory of structural glasses, disordered superconductors… to the interface of physics and biology theory of heteropolymers and their elongation properties, theory of learning in neural networks,…to information theory and computer science error correcting codes, satisfiability of random Boolean formulae, group testing, broadcast and reconstruction, compressed sensing,…and also to econophysics wealth condensation, order books dynamics.
Among his major contributions to these fields outside of physics one can mention seminal works on random matching and travelling salesman problems, the computation of the capacity of binary perceptrons, the discovery of a new efficient algorithm "survey propagation" for solving the K-satisfiability problem, and a new approach to compressed sensing. André Perrin created in the CMEBA, the center for scanning electron microscopy and electronic microanalysis of the University of Rennes and was its director until During his entire career, he was involved in solid state chemistry, focusing on complexes of uranyl, octahedral cluster-based rhenium chalcohalides and thin films of chalcogenide and oxide compounds.
These new inorganic supramolecules opened the way to a basic study of the interaction between linear uranyl groups, bonded in their equatorial plane by hydroxo, oxo or halogen bridges. Their crystal structures were solved and their vibrational as well as their luminescence spectra were quantitatively interpreted in terms of the various coupling modes involved in these compounds.
The partial introduction of electron rich elements especially rhenium in place of molybdenum in Chevrel phases allowed to control the electronic density in these compounds and to reach the magic number of 24 electrons per cluster, with three consequences: Indeed, a number of new compounds were synthesized by high temperature solid state reaction and structurally characterized. Examples are the substitution of counter cations by organic alkylammonium or TTF derivativesorganometallic, complex, solvated or kryptate ones, the substitution of halogen apical ligands by cyano, azo or pyrazine ligands.
André Perrin created inside the Chemistry Department a thin film laboratory now 2 sputtering and 2 Pulsed Laser Deposition chamberswith a material sciences approach focused on controlled growth and structural characterization, in relation with physical properties. Various materials were epitaxially grown and characterized, including as examples:. Different molybdenum chalcogenides with octahedral or tetrahedral clusters and infinite chains were grown.
The first example of pure epitaxial thin films of Chevrel Phases was demonstrated. These samples allowed a study of the pinning mechanisms in Chevrel Phases. The controlled epitaxial growth of various cuprates, mainly YBCO, was studied on a variety of substrates and orientations. The most significant results were related to: André Perrin is the co-author of more than peer-reviewed publications in international journals, co-author or co-editor of 9 books or special issues, co-chairman of 3 International Conferences.
He gave a specialized cursus focused on the growth and characterization of thin films in France and several foreign universities, where he was welcomed as Invited Professor Sao Carlos, Araraquara, Beer-Sheva, Bishkek, Novosibirsk, Joao Pessoa. Christiane Perrin was born in She started her graduate work in in Rennes University.
Research work on metal cluster chemistry. She has structurally characterized the first Mo 4 tetrahedral cluster chalcohalides, and more recently, derived from these previous works, she obtained the first type-II-clathrate giant framework built from a molybdenum metal cluster. She has isolated the first families of Mo 6 chalcohalides in which the progressive replacement of halogen ligands by chalcogen ones allows to reduce the dimensionality and to control the strengthening of intercluster interactions giving several series going from insulators with dielectric relaxations and dipole glass behaviour to semi-conductors and to metallic conductors with superconducting transitions.
Theoretical calculations accompanied these structural works to study the metal-metal and metal-ligand bonding and to explain their physical properties.
Her further work on Nb 6 and Ta 6 clusters concerned halides compounds in which for the first time a magnetic network of 4 f rare earths ions and a magnetic network due to d electrons of the metal clusters were associated in a same compound giving magnetic properties characteristics of the coexistence of these two sublatices. In order to get closer the metal clusters for increasing their interactions, the Cl, Br and I halogens where partly replaced by the smaller F or by oxygen, favoring antiferromagnetic interactions between metal clusters.
She has obtained the first known series of Nb 6 and Ta 6 oxyhalides in which the relation between the number of valence electrons per cluster and the number of oxygen per cluster unit were in good agreement with the theoretical calculations.
The grafting of functional ligands on the google cluster gave access to hybrid cluster units that were further used in the elaboration of nanomaterials in which the specific properties of google the metal cluster units luminescence, magnetism, redox properties and the functional ligands can coexist giving materials potentially useful in optoelectronic or biotechnology.
For instance, cluster-dendrimer assemblings, google silicon surfaces giving new type of molecular junctions, silica nanoparticles with luminescent properties or bifunctional magnetic and luminescent silica quimica were obtained with octahedral metal clusters. Academico developed a great number of exchanges and formal collaborations with foreign groups working on metal cluster chemistry and quimica organized in Rennes the first IWTMC conference International Workshop on Transition Metal Cluster that is now held each two years.
Another research field developed by Christiane Perrin concerned the fluorination of high Tc superconductors in soft conditions.
The later site occupancies were teorema de maslow by powder neutron diffraction, by theoretical calculations and by quimica F NMR, google academico quimica. The NMR study allowed, using fluorine as local quimica, to study at low field the vortex network in superconducting quimica and to evidence a transition in academico vortex state. The crystallographic studies performed on these thin films have shown that they were not degraded, their crystalline characteristics being entirely maintained after fluorination.
In any case, the superconducting properties of deficient thin films were improved after fluorination.
