SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:The seminar on Nanotechnologies\, Photoprocesses and Tissue Engineering\, applied in the treatment of SNC cancer and neurodegenerative diseases\, which will be given by Pr. Antonio Tedesco from the University of São Paulo\, Brazil. The seminar will take place at Chimie ParisTech-PSL\, lecture hall Henri Moissan\, on Thursday\, June 22 at 10:30.  \nYou will find an abstract below.  \nThe combination of three research fields involving Nanotechnology\, Photoprocesses\, and Tissue-Engineering\, was the path chosen by our group to generate scientific knowledge and technology to treat many CNS pathologies.  Nanomedicine is undoubtedly the area of ​​health that can most quickly benefit from these advances. Photoprocesses\, conversely\, encompass therapies that use visible light as an inducer and comprise Phototherapy and Photobiomodulation. We have been working on the development of a new drugs system (DDS)\, mainly applied to the treatment of cancer (skin\, cervix\, lung\, bladder\, prostate\, and breast) and pathologies that affect the central nervous system (CNS)\, such as Parkinson’s\, Alzheimer’s\, and Brain cancer.  Tissue Engineering\, or Regenerative Medicine\, could be successfully used with Nanotechnology and Photoprocesses\, where tissue growth and regeneration are increasingly used. The basic principle behind all these studies starts with choosing an active or photoactive molecule that absorbs visible light that will be controlled and released on the target tissue. Then it will be bio-stimulated by visible light\, leading to a biological response that can induce cancer cell death\, healing-wound process\, and CNS diseases. We believe that the approaches developed can bring positive results to patients ’lives quickly.

SUMMARY:Séminaire Programme Gradué Chimie PSL
DESCRIPTION:Tuning structural and electronic phase transitions in elastic media By Prof. Gian G. Guzmán-Verri\, Universidad de Costa Rica\, San José\, Costa Rica. Room Holweck\, building C\, 1st floor\n\n \nIn complex functional materials\, the primary drivers of their phase transitions are instabilities of different nature such as magnetic\, polar\, charge or orbital. It is also well known that many of those transformations can be tuned by parameters such as ionic size in a chemical series\, sometimes without causing significant changes to their local energy structure. In this talk\, I want to argue that even when the transition is clearly driven by a local instability\, strain mediated interactions between the primary degrees of freedom can produce enormous entropic contributions to the free energy that are usually ignored by conventional theories. I will illustrate this idea with a phenomenological theory in which the primary order parameter of the phase transition is coupled to elastic strains and strain gradients in three classes of materials\, namely the colossal magnetoresistance manganites [1]\, the perovskite quantum paraelectrics [2]\, and the tellurides [3].\n \nWork supported by the Vicerrectory for Research at the University of Costa Rica.\n \n[1] G.
