El viernes 22 de mayo se celebró por primera vez nuestro Nano Days Virtual.  Nuestro equipo de investigadores, estudiantes graduados y subgraduados trabajaron arduamente para celebrar nuestro querido Nano Days para llevar ciencia, tecnología y diversión al público en general durante la situación difícil en la que nos encontramos como país y mundo.  Los participantes de CIRE2N realizaron una serie de videos demostrativos basados en temas pertinentes a su respectivo IRG.   Esta actividad libre de costo se realizó a través de Facebook Live durante las horas de 10:00am a 3:00pm durante en las cuales se llevaron a cabo una [...]

Proyect Based Learning Workshop

By |2019-09-27T13:20:07-04:00September 16th, 2019|Categories: News, Uncategorized|Tags: , , , , , , , , , , , , , , |

There was a workshop on Proyect Base Learning last Friday September 13, 2019. The workshop was presented by the doctoral student, Ana Fernández Ruíz. Proyect Base Learning is"an effective teaching model that focuses the learning process on a real project that is relevant to the student". In CIRE2N, we use this learning process with our students. They learn while engaging in activities and research in Environmental Nanotechnology with scientists from different universities. This workshop, that was atended by 15 CIRE2N students, helps them understand this teaching model so they know how to use it in the future.   #NSFfunded #NSFCrest

Chemistry in Pictures: Fluorescence unmasked

By |2019-03-20T11:32:32-04:00March 20th, 2019|Categories: News, Uncategorized|Tags: , , |

Article by: Manny Morone Credit: Jon Grimm While synthesizing fluorescent dyes like these, Jon Grimm of Janelia Research Campus often has to mask or “protect” parts of his molecules with functional groups that are less reactive. This step allows him to modify one part of the dye molecule without undoing the work he did on another. The protected versions of the molecules are colorless. But when Grimm adds sodium hydroxide or tetra-n-butylammonium fluoride (TBAF) to the protected molecules, they lose their protecting groups, revealing their colors and fluorescing under ultraviolet light. Grimm works with Janelia’s chief toolmaker Luke [...]

Interactive demonstrations: Cayey Christian Academy

Nanofiber carpet could lead to new sticky or insulating surfaces

By |2018-12-12T09:55:08-04:00December 12th, 2018|Categories: News|Tags: , , , , |

Inspired by the extraordinary characteristics of polar bear fur, lotus leaves and gecko feet, engineering researchers have developed a new way to make arrays of nanofibers that could bring us coatings that are sticky, repellent, insulating or light emitting, among other possibilities.

‘Smart skin’ simplifies spotting strain in structures

By |2018-11-28T10:49:39-04:00November 28th, 2018|Categories: News|Tags: , , , , |

A 'smart skin' employs the unique fluorescent characteristics of carbon nanotubes to quickly assess strain in materials. The method is intended for aircraft, spacecraft and critical infrastructures in which mechanical strain needs to be monitored.

Watching nanoparticles: Researchers make movies of photochemistry in single nanoparticles

By |2018-11-15T14:54:36-04:00November 15th, 2018|Categories: News|Tags: , , , , , |

Stanford researchers retooled an electron microscope to work with visible light and gas flow, making it possible to watch a photochemical reaction as it swept across a nanoparticle the size of a single cold virus.
