Gujrat, Pakistan

The University of Gujrat is one of the new major public sector universities in Punjab. The university was established under Act IX of 2004 by Government of Punjab, Pakistan on 23 February 2004 to cater for the higher education needs of the population of Central Punjab which includes districts of Gujrat, Sialkot and Gujranwala in addition to city of Wazirabad. These districts are popularly known as the Export Triangle of Pakistan due to various manufacturing industries operating in the area. Sir Syed Ahmad Khan founder of Aligarh Muslim University had named the region around Gujrat as "Khita-e-Younan", or "territory resembling ancient Greece", in reference to the high number of educational institutes present in the area in the 19th century. The University is promoting research and development culture in the area. A large number of students from Bhimber Azad Kashmir also study in the university.The Main Campus has been named after a local Sufi saint Hafiz Muhammad Hayat. Situated prominently in the University of Gujrat campus, the shrine of Hafiz Hayat is an exquisite complex in terms of its architecture, site planning and landscape design. It is located on a mound six feet high above the Terre plain. The site contains a haveli, summerhouse , mosque, four tombs of varying dimensions, several graves, seven wells and numerous old trees. The mound on which the construction was carried out belonged to the Raja Kaladhvi and was surrounded by a dense forest at that time. Hafiz Hayat settled in the area and helped people with his spiritual charisma. Although the exact dates are not known yet according to popular belief it was at the time of Emperor Jahangir. The saint donated his entire land holding to the then state authorities for the cause of education. The main campus of UOG has been constructed on that very land donated by Hafiz Muhammad Hayat.

The electronic, structural and magnetic properties of Mn doped cadmium sulfide Cd1- xMnxS (x = 6.25% and x = 3.125%) are studied using spin-polarized density functional theory, in the framework of Local Density Approximation (LDA), Generalized Gradient Approximation (GGA), their extensions via on-site Hubbard U interactions and Tran Blaha modified Becke-Johnson (TB-mBJ) model potential. The Ferromagnetic interactions are studied between two Mn atoms via S atom due to strong p-d hybridization and d-d interactions. The ferromagnetic (FM) and anti-ferromagnetic (AFM) coupling properties between these atoms are studied with and without sulfur vacancies. The magnetic moments on Cd, S and Mn-atom are studied in detail by using different charge analysis techniques. The p-d hybridization reduces the local magnetic moment on Mn from its free space charge value and produces small local magnetic moments on the nonmagnetic Cd and S host sites. Mn doped CdS provides p-type semiconductor with d-states at top of the valence band edge, these states are responsible for a very useful luminescent and magneto-optical Mn:CdS material. © 2015 Published by Elsevier B.V.

Cerium ions were implanted into wurtzite GaN/sapphire thin films at doses 3 × 1014 and 2 × 1015 cm-2. The samples were annealed at 900 °C and studied using photoluminescence (PL), Raman, optical transmission spectroscopy and Hall measurement techniques. Near band emission signs were found absent for implanted samples and two new luminescence centers were recorded. Detailed temperature dependence PL measurements were carried out to find possible origin of these centers. The observed luminescence lines are assigned to the radiative recombination of electrons bound to the complex CeGa-VN and isoelectronic CeGa traps with holes from valance band. © 2013 American Institute of Physics.

The excitation of surface plasmon polaritons (SPPs) through one-dimentional (1D) metallic (Au) grating on higher refractive index -GaP substrate is investigated. Such grating devices find potential applications in real world, only if the coupling efficiency (η) of a free-space transverse-magnetic plane-wave into a SPPs mode is maximum. A simple and robust technique is used to estimate the η, by simply measuring the transmission through the grating while varying slit width (a) but period (Λ) and the thickness (t) remain fixed. When the wave vector (k0) of the incident light is matched to that of SPP, highest η is achieved. It is found that Λ/3 < a < Λ/2 yields a maximum η where the intermediate scattering couples more incident energy to SPPs. These gratings are designed in such a way that they support only the fundamental plasmonic mode yielding higher η. Scanning near-field optical measurements also confirm and corroborate the observations of far-field and near-field modeling (COMSOL multiphysics) results. © 2016 Springer Science+Business Media New York

Contemporary medicinal chemistry faces diverse challenges from several directions, including the need for both potency and specificity of any therapeutic agent. Therefore, in the present perspective, the triazolothiadiazoles and triazolothiadiazines with broad spectrum biological profile have matured into indispensable heterocyclic scaffolds. This review article is an effort to summarize medicinal chemistry investigations over the last decade, in search for new N-bridged heterocycles which can be a rich source of promising biological activities. © 2013 Elsevier Masson SAS.

This paper reports the excitation of surface plasmon polaritons (SPPs) and associated plasmonic band gap (PBG) while using TM plane wave interacting with 1D metallic grating on higher refractive index GaP substrate. A simple method is introduced to estimate the PBG which is crucial for many plasmonic devices. The PBG is estimated by measuring the transmission spectra obtained through the plasmonic grating structures when slit width is varied while periodicity and the thickness of the gold (Au) film remained fixed. The PBG is observed for the grating devices whose slit width is less than one third of the periodicity which is caused by the presence of a higher plasmonic mode. The PBG is absent for the grating device whose slit width is slightly less than half and greater than one third of the periodicity. Such grating devices support only a fundamental plasmonic mode because the profile/shape of the slit in the grating device is more like a sinusoidal nature. Furthermore, such grating offers intermediate scattering to the incident light and the SPP as well which in turn couple more incident energy to the SPPs. Far-field modelling results also support the results obtained through experiment. © 2015 Springer Science+Business Media New York
