      • On the Nature Of Propagating MHD Waves In The Solar Atmosphere 

        Gupta, Girjesh R (2014-10-15)
        One of the most persistent problem in solar physics is the identification of the mechanism that heats the solar corona and accelerates the fast solar wind. Magneto-hydrodynamic (MHD)waves play a crucial role in heating of ...
      • One Dimensional Transport And Prospects Of Structural Transitions In Ultrathin Metallic Wires 

        Chandni, U (2013-02-25)
        This thesis reports transport in ultrathin single crystalline nanowires of gold (∼ 2nm). These nanowires were fabricated using an oriented attachment process whereby nanoparticles of appropriate dimensions join in a linear ...
      • Optical Absorption And Fluorescence Properties Of Rare Earth Ions (Nd3+, Sm3+ And Dy3+) In Lead Borate And Bismuth Borate Glasses 

        Saisudha, M B (2012-06-07)
      • Optical And Structural Investigations Of Defects In CdZnTe(Zn ~ 4%) Crystals 

        Kulkarni, Gururaj Anand (2013-06-12)
        The CdTe family members (in particular CdZnTe) remain the substrate of choice for epitaxial growth of HgCdTe for use in high performance infrared (IR) detectors and focal plane arrays. This is the case despite advances in ...
      • Optical Diffraction Tomography for the Refractive Index Profiling of Objects with Large Space-Bandwidth product 

        John, Jem Teresa (2018-05-25)
        The primary goal of this work is to arrive at direction tomography (DT) algorithms freed from the severe linearization in the formulation, and as-assumptions on variation of the refractive index distribution (RID), involved ...
      • Optical Tweezers and Its use in Studying Red Blood Cells - Healthy and Infected 

        Paul, Apurba (2017-11-29)
        The experiment discussed in the next chapter was to confirm the aforementioned bystander effect. In the first experiment we separated hosting and non-hosting mRBCs by the percol purification method and then measured the corner ...
      • Optical Tweezers To Probe And Manipulate Soft, Nano And Bio Systems 

        Khan, Manas (2013-01-31)
        Statistical physics in soft matter systems, physical properties of bio-inspired systems and the mechanical manipulations of nano-systems have been studied using optical tweezers to form the basis of this doctoral Thesis. ...
      • Optical, AC Conductivity, NMR and Raman Studies of Alkali Borogermanate Glasses 

        Sunil Kumar, S (2017-11-22)
        Physical properties of materials and their constituents are interrelated. Though the basic structural unit involved also plays a role in deciding the properties, this can be manipulated to a certain extent, by carefully ...

        Manu, V S (2017-05-21)
        Genetic algorithms (GA) are stochastic global search methods based on the mechanics of natural biological evolution, proposed by John Holland in 1975. Here in this thesis, we have exploited possible utilities of Genetic ...
      • Optoelectronic Properties of Graphene Based Van-der-Waals Hybrids 

        Roy, Kallol
        Light matter interactions in atomically thin van der Waals materials have attracted significant attention in recent day [1–6]. Although the thickness does not exceed few nano-meters, such an atomically thin materials alone ...
      • Orbital Evolution And Super-Orbital Flux Variations In X-ray Binary Pulsars 

        Raichur, Harsha (2010-08-23)
