Development Of Fluorescent OLED And Analysis Of Integrated Optofluidic Lab-on-a Chip Sensor
(2014-04-15)
Optofluidics is a new branch within photonics which attempts to unify concepts from optics and microfluidics. Unification of photonics and microfluidics enable us to carry out analysis of fluids through highly sensitive ...
"Optical Diffraction By Micro Cylinder" - A Few Investigations
(2013-04-04)
Micro-cylinders with the diameters spanning the 1-20 μm range are growing in importance, for realizing devices with new functionalities. For custom functionalities, their device-designs impose, tolerance-related constraints ...
Semi Conducting Metal Oxide Gas Sensors: Development And Related Instrumentation
(Indian Institute of Science, 2007-05-21)
A sensor is a technological device or biological organ that detects, or senses, a signal or physical condition and chemical compounds. Technological developments in the recent decades have brought along with it several ...
Novel Methods To Interrogate Fiber Bragg Grating Sensors
(2013-02-14)
A novel detection technique to estimate the amount of chirp in fiber Bragg gratings (FBGs) is proposed. This method is based on the fact that reflectivity at central wavelength of FBG reflection changes with strain/temperature ...
A Preliminary Study Of Fields In Split-Electrode Ion Traps
(2014-08-20)
Ion traps used in mass spectrometers are of two classes. One class consists of traps having three electrode geometries which have rotational symmetry about central axis. They are called axially symmetric ion traps. Paul ...
Numerical Study of Directionality of Ion Ejection In Axially Symmetric Ion Traps
(2013-02-13)
In the normal operation of quadrupole ion trap mass spectrometers, the trapped ions are ejected symmetrically through both the upper (detector) and lower(source) endcap electrodes during mass selective boundary ejection ...
Escape Of High Mass Ions Due To Initial Thermal Energy And Its Implications For RF Trap Design
(2013-05-31)
This thesis investigates the loss of high mass ions due to the initial thermal energy in ion trap mass analyzers. It provides an analytical expression for estimating the percentage loss of ions of a given mass at a particular ...
Axially Symmetric Equivalents Of Three-Dimensional Rf Ion Traps
(2013-09-13)
This thesis presents axially symmetric equivalents of three-dimensional rf ion traps. Miniaturization in mass spectrometry has focused on miniaturizing mass analyzers. Decrease in mass analyzer size facilitates reduction ...
A Preliminary Investigation Of The Role Of Magnetic Fields In Axially Symmetric rf Ion Traps
(2013-07-16)
Axially symmetric rf ion traps consists of a mass analyser having three electrodes, one of which is a central ring electrode and the other two are endcap electrodes. In the ideal Paul trap mass spectrometer, the electrodes ...
Ultrasound Assisted Optical Elastography For Measurement Of Mechanical Properties Of Soft Tissue Mimicking Phantoms
(2009-03-03)
This work describes the development of an optical probe for measuring movement of tissue particles deep inside which are loaded by an ultrasound remote palpation device. The principle of the method is that ultrasound force ...
