Enhancement of Low-energy Electron Emission in 2-D Radioactive Films
Radioactive decay and its accompanying high-energy radiation are well understood and have been utilized for decades. However, the role of low-energy electrons created during irradiation has only recently begun to be appreciated. Low-energy electrons are the most important component of radiation damage in biological environments because they have subcellular ranges and interact destructively with chemical bonds. Their short ranges make them ideal for targeted cancer therapies, yet methods for generating them locally do not exist.
Colloidal Superparticles: A New Frontier of Nanomaterials
Colloidal superparticlesare nanoparticle assemblies in the form of colloidal particles.Assembling nanoscopicobjects into meso/macroscopic complex architectures allows bottom-up fabrication of functional materials, which is essential for many nanomaterial-based technological applications.In this colloquium, we will discuss the formation of superparticleswith supercrystallinestructures made from the self-assembly of nanoparticles with a verity of chemical compositions and with well-defined size and shapes.

Shape-shifting groups of nanorods release heat differentlyFebruary 18, 2015

Researchers at Argonne have revealed previously unobserved behaviors that show how the transfer of heat at the nanoscale causes nanoparticles to change shape in groups.

Models for Coherent and Incoherent Electronic Transport In Organic Semi-conductors
In this talk I present recent models for the analysis of electronic transport in organic semi-conductors. In the first case, [1], a tight-binding model of coherent electronic transport through molecules allows to derive simple rules for the zero-voltage conductance of nanographenes and Polycyclic Aromatic Hydrocarbons (PAH). One particularly interesting prediction is the vanishing zero-voltage conductance in certain nanographene. Even though these systems are Π conjugated, from the conductance point of view they consist of disconnected parts.
Nanomanufacturing: Is There Life Beyond Silicon?
Photolithography applied to the fabrication of integrated circuits in silicon is the preeminent nanomanufacturing technology and has transformed our world. The functionality and value provided per unit area by silicon are extraordinary by any measure. As a consequence, it is economically viable to use very capital-intensive fabrication processes to generate the required nanostructures.
