Workshop on Nanomaterials

Registration: 
Open to all.
Date:

Time:

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.

Numerical Simulations of RF Induced Heating in MRI

Registration: 
Open to all.
Date:

Time: 
11:00 am
Venue: 
M.Sc. Seminar Room, University of Engineering and Technology (UET), Lahore
Abstract: 

MRI (Magnetic Resonance Imaging) is a very useful medical procedure to get high quality images inside the body. Felix Bloch and Edward Purcell discovered the magnetic resonance phenomenon independently in 1946. They were awarded the Nobel Prize in 1952. The use of MRI is increasing every day and has become a very useful tool for diagnosis. However, patients with artificial implants, e.g. heart pace makers, DBS (Deep Brain Stimulation) systems, which are used for Parkinson's disease, IPG (Implantable Pulse Generator), used for generating pulses for DBS, are in severe danger for MRI testing. The problems for such patients going under MRI are that the generation of the induced eddy currents inside the metallic implants that causes heating. This heating, if goes above a certain level, can cause brain damage and can even result in death. We are doing numerical computations using FDTD (Finite Difference Time Domain) to estimate the heating produced inside the body using the human data set.

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.

Smart Antenna Applications for Code Division Multiple Access Wireless Systems

Venue: 
M.Sc. Seminar Room, Electrical Engineering Department, University of Engineering and Technology (UET), Lahore
Abstract: 

Wireless communications for mobile telephone and data transmission is currently undergoing very rapid development. The emerging wireless systems will incorporate considerable signal processing intelligence in order to provide advanced services such as multimedia transmission. In order to make optimum use of available bandwidth, many wireless systems operate as multiple access systems, e.g. Direct Sequence Code Division Multiple Access (DS-CDMA), in which the users are multiplexed by distinct code waveforms. Two major factors that limit the performance of DS-CDMA systems are multiple access interference and multipath channel distortion. Many advanced signal processing techniques have been proposed to combat these factors. Among these techniques, one of the more promising is the use of Smart or Adaptive antennas. This seminar provides an introduction to Smart Antennas for cellular systems. It looks at the various factors affecting propagation in a wireless channel environment and reviews the different approaches towards implementation of adaptive beamforming algorithms for CDMA systems. Finally it reports on the simulation strategy adopted to evaluate the performance of smart antenna systems for CDMA.
