Nanoengineering and Fabrication of Intelligent Devices that can Shape the Future

Registration: 
Open to all.
Date: 
21 May 2006
Time: 
11:00 am
Venue: 
Faisal Library, University of Engineering and Technology (UET), Lahore
Abstract: 

This talk will be focused on some of the scientific themes and applications in which electron energies reached for device or process operation are above that of the surrounding lattice or environment. Within the scope of the topic I will attempt to describe the vision of the global nanoscience community which is to 'exploit science in the nano-scale to inspire intelligent devices that can shape the future'. Freeman Dyson once said; "Technology is a gift of God. After the gift of life it is perhaps the greatest of God's gifts. It is the mother of civilizations, of arts and of sciences." With this in mind, I will also talk about what we can do to help take our ideas in the exploitation of knowledge to build good technologies for the future. Examples associated with the scale up of plasma technologies for the growth of carbon nanotube systems, use of organic nanocomposites for the production of solar cells and the novel processing routes of materials for display products and next generation transistors will be utilized. Novel Processes such as Ion beam lithography, Focused ion beams, Smart cut and Dual platform systems are versatile tools for nanoengineering and nanoscience applications and can be used to rapidly prototype and modify a diverse range of nano-devices and sensors. I will discuss the use of these systems for nanoengineeing and fabrication using examples from research.

Nanostructures and their Applications

Registration: 
Open to all.
Date: 
19 May 2006
Time: 
11:00 am
Venue: 
Faisal Library, University of Engineering and Technology (UET), Lahore
Abstract: 

The talk will be based on synthesis and applications of nanostructures in various areas like energy, photonics, and biology. With the tools available to fabricate devices from top down approach, it is utmost desire to develop techniques, which mimic nature, i.e., assemble atoms and molecules in a manner that these can be used for applications. A lot of effort is being carried out to control the growth of matter at nanoscale. The talk will cover fundamentals of self-assembly and then use of nanostructures/nanoparticles in a variety of devices.

Magnetic Resonance

From Brain Tissue to Chloroform Computers
Registration: 
Open to all.
Date: 
09 May 2007
Time: 
11:00 am
Venue: 
Institute of Biochemistry and Biotechnology, University of the Punjab, Quaid-e-Azam Campus, Lahore
Abstract: 

Nuclear magnetic resonance (NMR) is a technique that exploits the spin of certain nuclei to obtain a tell-tale signatures of the molecule. This technique finds immense use in diagnostic imaging of human tissue. We will explore the origins of the NMR effect. In addition to its medical uses, we will also address other novel and esoteric applications, such as quantum computing, low-field NMR, explosives detection, polymer and foodstuff characterization, single-cell and nanoparticle MRI.

The Four Greatest Ideas in Physics

Registration: 
Open to all.
Date: 
14 October, 2003
Time: 
4 pm
Venue: 
Ali Auditorium, Ali Institute of Education, Ferozepur Road, Lahore
Abstract: 

In his address, the speaker Prof. Dr. Pervez Hoodbhoy aptly explained the four greatest ideas in physics: relativity, quantum mechanics, electro-weak unification and the string theory. These ideas had changed the very face of twentieth century physics and taken mankind into more exciting nooks and corners of the known and the unknown universes. The content of the lecture was aimed for the lay masses, and therefore commanded a lot of eager interest from people of all backgrounds. The lecture was followed by an active question and answer session, lasting another thirty minutes.

Workshop on Nanomaterials

Registration: 
Open to all.
Date: 
15 December 2003
Time: 
11:00 am
Venue: 
Centre for Solid State Physics, University of the Punjab, Quaid-e-Azam Campus, Lahore
Abstract: 

Nanotechnology is design, fabrication and application of nanostructures or nanoparticles, and the fundamental understanding of the relationships between physical properties or phenomena and material dimensions. Nanotechnology is a new field or a new scientific domain, dealing with materials or structures in nanometer scales, typically ranging from sub-nanometers to several hundred nanometers. Nanotechnology also promises the possibility of giving non-conventional properties. Yet another very important aspect of nanotechnology is the miniaturization of current and new instruments, sensors and machines that will greatly impact the world we live in. Examples of possible miniaturization are: biosensors that warn us at the early stage of the onset of disease and preferably at the molecular level and target specific drugs that automatically attack the diseased cells on site, nanorobots that can repair internal damage and remove chemical toxins in human bodies, and nanoscaled electronics that constantly monitor our local environment. Synthesis and processing of nanostructures and nanoparticles are the essential aspect of nanotechnology. Studies on new physical properties and applications of nanostructures and nanoparticles are possible only when these materials are made available with desired size, morphology, crystal structure and chemical composition. The research on nanotechnology is evolving and expanding very rapidly. This workshop will focus primarily on synthesis of inorganic materials. The aim is to summarize the fundamentals and established techniques of synthesis and processing of inorganic nanostructures and nanoparticles so as to provide the audience with a systematic and coherent picture about synthesis and processing of nanomaterials. In addition, a small part of the talk will be devoted to characterization, properties and applications of nanomaterials and nanostructures. This presentation would serve as a general introduction to people just entering the field, and also for experts seeking for information in other subfields.

Transport Phoneomena at the Nanoscale

Registration: 
Open to all.
Date: 
9 April, 2003
Time: 
11:00 am
Venue: 
Institute of Biochemistry and Biotechnology, University of the Punjab, Quaid-e-Azam Campus, Lahore
Abstract: 

The development of Nanotechnology has enabled the possibilities to fabricate devices and structures at nanoscale (on the order of few nm). The properties of such nanostructures cannot be described by macroscopic physical models like drift-diffusion equations. And that is where the fundamental constants of nature (e.g. charge of an electron, Planck's constant, spin of an electron, etc) come into play. The purpose of this seminar is to describe how these fundamental constants can be connected with the transport phenomenon at nanoscale and how we can come up with a formalism that can describe the transport phenomenon in these nanostructures in terms of the atomistic theory of matter. We will start with a simple one level model to describe transport through individual molecular levels and then extend our discussion to transport through quantum wires using Nonequilibirum Green's Function (NEGF) methodology. Then we will discuss how to include interactions in our formalism which will connect this formalism to Ohm's Law.
