Plasmon active metals (gold and silver) along with chalcogenide glass have been used to enhance electric field intensity by 360% thereby significantly affecting the study of biomolecular interactions occurring in the vicinity of metal-analyte interface.
We report here results on charm and strange hadron spectra. Adopting a mixed action approach, we use overlap fermions for valence quarks, on a background of 2+1+1 flavours HISQ gauge configurations of MILC collaboration. Two lattice spacings (0.09 fm and 0.06 fm) are used. We find the hyperfine splitting of 1S charmonia to be 114+3 −2 MeV and 109+4 −3 MeV, and the splitting (mΩccc − 3 2mJ/Ψ) is found to be 110+20 −10 MeV and 120(10) MeV, corresponding to lattices with spacings a = 0.09 and 0....
This paper examines and explores the web impact factor through a webometric study of the present 16 Indian Institute of Technology (IIT) of India. Identifies the domain systems of the websites; analyzes the number of web pages and link pages, and calculates the simple web impact factor (WIF), self link web impact factor and external web impact factor of all the IIT. Also reflects that some IIT have higher number of web pages, but correspondingly their link pages are very small in numb...
An analysis is presented for appreciating the mechanism of coupling of surface plasmon and bandgap guided modes. A design principle is proposed for designing such geometries and dispersion properties are studied by varying waveguide parameters.
Here, 2,4-dinitrophenylsulfonamides with tunable cysteine-activated SO2 release profiles with half-lives of SO2 release varying from 2 to 63 min are reported. N-Benzyl-2,4-dinitrobenzenesulfonamide (6), which is prepared in one step from commercial sources, had a potency (MIC = 0.15 μM) of inhibiting Mycobacterium tuberculosis (Mtb) higher than the clinical agent isoniazid (MIC = 0.37 μM).
Rotational dynamics of two neutral organic solutes, coumarin-153 (C-153) and 4-aminophthalimide (AP), with only the latter having hydrogen-bond-donating ability, has been investigated in a series of 1-ethyl-3-methylimidazolium alkyl sulfate ionic liquids as a function of temperature. The ionic liquids differ only in the length of the linear alkyl side chain (alkyl = ethyl, butyl, hexyl, and octyl) on the anionic moiety. The present study has been undertaken to examine the role of alkyl side c...
The solvent relaxation and rotational dynamics of coumarin 153 have been investigated in a new room temperature ionic liquid, 1-(2-methoxyethyl)-1-methylpyrrolidiniumtris(pentafluorethyl)trifluoropho sphate [[MOEMPL][FAP]], at three different excitation wavelengths with a variation in temperature. Wavelength-dependent fluorescence decay behavior of the probe molecule in the present medium has been investigated by studying the time dependent fluorescence Stokes shift in the ps–ns time s...
Here, we report that thiol-mediated decomposition of 2,3-epoxy-1,4-naphthoquinones to generate peroxide, a reactive oxygen species (ROS), could be modulated by changing the substitution pattern on the aryl ring and the epoxide. Epoxides which generated higher amounts of peroxide upon reaction with thiols were better inhibitors of human leukaemia (THP1) cell proliferation.
Highly sensitive, accurate and stable high temperature (800 K) sensor based on Photonic Crystal Surface Plasmon Waveguides is proposed. The PCW is based on widely used lithographic and nano-fabrication compatible materials like TiO2 and SiO2. Gold has been used as a SPR active metal. Employing coupled mode theory, the sensitivity is found to be as high as ~ 66 pm/K.
The effect of the binding of pyridine ligands to pentafluorophenyl copper, [C6F5Cu]4 (1), on structural features and photophysical properties has been investigated through a combined multinuclear NMR, X-ray crystallography, and photoluminescence study. Reaction of 1 with 2 equiv of pyridine yields a novel pyridine complex, 3, in which the tetranuclear framework of 1 is retained. Complex 3 features a rhombus-shaped tetracopper core with a short diagonal Cu···Cu distance of 2.5941(6) Å between ...
