Scanning Probe Microscopes and their remarkable ability to provide three-dimensional maps of surfaces at the nanometer length scale have arguably been the most important tool in establishing the world-wide emergence of Nanotechnology. In this talk, the fundamental ideas behind the first scanning probe microscope – the Scanning Tunneling Microscope (STM) – will be reviewed. By controlling quantum mechanical electron tunneling, an exquisitely sensitive probe can be built to measure height variations above a surface at the picometer (10 -12 m) level. Some of the historically important problems solved by STMs will be discussed and a few of the important design principles required to build an STM will also be outlined.

This course will provide students with the fundamentals of computational problem-solving techniques that are used to understand and predict properties of nanoscale systems. Emphasis will be placed on how to use simulations effectively, intelligently, and cohesively to predict properties that occur at the nanoscale for real systems. The course is designed to present a broad overview of computational nanoscience and is therefore suitable for both experimental and theoretical researchers. Specific …

In this lecture, we continue our discussion of Monte Carlo simulation. Examples from Hard Sphere Monte Carlo simulations based on the Metropolis algorithm and from Grand Canonical Monte Carlo simulations of fullerene growth on spherical surfaces are presented. A discussion of meaningful statistics, result interpretation, and error analysis is presented as well.University of California, Berkeley.

The purpose of this lecture is to introduce Monte Carlo methods as a form of stochastic simulation. Some introductory examples of Monte Carlo methods are given, and a basic introduction to relevant concepts in statistical mechanics is presented. Students will be introduced to the Metropolis approach to Monte Carlo simulation. Using Metropolis as an example, these lectures also introduce the comcepts of balance and detailed balance, and what “efficient sampling” means.

This lecture provides and introduction to Quantum Monte Carlo methods. We review the concept of electron correlation and introduce Variational Monte Carlo methods as an approach to going beyond the mean field approximation. We describe briefly the Slater-Jastrow expansion of the wavefunction, and show how we can recover the some of the correlation energy using a variational approach to optimizing this form of the wavefunction.Lucas K.

Nanoparticles cause cancer cells to self-destruct

The researchers have used nanoparticles of iron oxide that have been treated with a special form of magnetism. Once the particles are inside the cancer cells, the cells are exposed to a magnetic field, and the nanoparticles begin to rotate in a way that causes the lysosomes to start destroying the cells.
