Nano manipulation
(Experiments in Nanoscale) 

Today nanotechnology is one of the most fascinating research fields. This is because materials in nanometer scale (nanostructures) exhibit size dependent physical and chemical properties. In addition, there is a great interest to employ nanostructures for fabrication of micro- and nano-scaled electronic devices. In fact, in recent years, the enormous efforts and interests in this field resulted in knowledge, skills and advanced techniques that have made it possible to design and execute experiments in nanoscale. For example, nowadays it is possible to perform experiments on nanostructure inside advance electron microscopes and live track any structural change with even atomic resolution imaging. This lecture will describe some of the recent advances in electron microscopy and how it is shifting the research frontiers in different fields.

Hamid Reza Barzegar

is a senior researcher at the Physics Department and he has established the research group “Atomically Thin and Layered Material”. The main focus of the group is on the synthesis of novel nano-materials as well as investigation of their fundamental properties and applications via advanced characterization techniques.


Nanomaterials design:
A tale of control and manipulation

Human needs and desires have historically directed the development of materials, and it is unlikely to change any time soon. Meaning that several new materials with tailored properties will be needed to meet future demands in diverse fields; from clean energy generation up to personalized consumer products. The timely development of such materials will require the use of large scale experimentation, as well as control and manipulation of matter at the atomic level, and so, the use of nanomaterials is inevitable. Nanomaterials comes in a large variety of shapes and flavors, and they have a plethora of interesting properties, but their size makes them highly vulnerable to structural alterations that can drastically changes their properties, this being both a blessing and a curse. In this lecture we will see how delicate nanomaterials can be, and the resulting challenges during production.

Eduardo Gracia

is an assistant professor in the Department of Physics at Umeå University. His research group study defective and disordered nanomaterials with focus on understanding their structure and find out the intricate relationship between their atomic configuration and their electrical, chemical, and catalytic properties.
