A novel "pro-sensitizer" based sensing of enzymes using Tb(III) luminescence in a hydrogel matrix

Chemically synthesized "pro-sensitizers" release the sensitizer in the presence of lipase or β-glucosidase, triggering a significant luminescence response from a lanthanide based hydrogel.     

Absorption spectra of nitroanilines in micellar solution--II

The absorption spectra of nitroanilines (o-, m- and p-) in aqueous and nonaqueous solution of neutral surfactant-Triton X-100 (TX-100) reveal many interesting phenomena. Nitroanilines and TX-100 behave as electron acceptor and donor, respectively, in both media during charge-transfer (CT) complex formation though water plays an important role in aqueous media. The thermodynamic and spectrophotometric parameters of nitroanilines-TX-100 interactions in two media have been determined and the electron accepting capability among the nitroanilines have been also established. In addition to this, role of surface in CT interaction, the site of CT interaction, intensity and stability of CT interaction between nitroanilines and TX-100 have been pointed out.     

Exact solutions,conservation laws,bifurcation of nonlinear and supernonlinear traveling waves for Sharma–Tasso–Olver equation

In the present work, we observe the dynamical behavior of nonlinear and supernonlinear traveling waves for Sharma–Tasso–Olver (STO) equation. Exact solutions are derived using \({1}/{G^{^{\prime }}}\) expansion and modified Kudryashov methods. The wave transformation is used to transform STO equation into an ordinary differential equation. Combining Runge–Kutta fourth-order and Fourier spectral technique, we use a mixed scheme for the numerical study of STO equation. Since spectral methods expand the solution in trigonometric series resulting into higher-order technique and Runge–Kutta produces improved accuracy, we extract these qualities for a mixed scheme. Results so produced are presented graphically which provide a useful information about the dynamical behavior. Bifurcation behavior of nonlinear and supernonlinear traveling waves of STO equation is studied with the help of bifurcation theory of planar dynamical systems. It is observed that STO equation supports nonlinear solitary wave, periodic wave, shock wave, stable oscillatory wave and most important supernonlinear periodic wave.     

Quasiparticle structures in118Te

The structure of¹¹⁸Te has been investigated following the¹¹⁰Pd(¹³C,5n) reaction using gamma-ray spectroscopic techniques and a substantially extended level scheme is proposed. A negative parity quasirotational band based on πg_7/2h_11/2 configuration has been established upto J^π=19. The level structure, above the fully aligned πg²7/2?vh²11/2 J^π=16⁺ yrast state, is found to evolve into several non-collective states.     

Superconducting linear accelerator system for NSC

This paper reports the construction of a superconducting linear accelerator as a booster to the 15 UD Pelletron accelerator at Nuclear Science Centre, New Delhi. The LINAC will use superconducting niobium quarter wave resonators as the accelerating element. Construction of the linear accelerator has progressed sufficiently. Details of the entire accelerator system including the cryogenics facility, RF electronics development, facilities for fabricating niobium resonators indigenously, and present status of the project are presented.     

Electric quadrupole moment of the 9/2− isomer in171Ta

The electric quadrupole moment of the 9/2^– isomer in the¹⁷¹Ta nucleus, populated in the¹⁵⁹Tb(¹⁶O,4n)¹⁷¹ Ta reaction, has been measured for the first time using the TDPAD technique. The measured value Q(9/2^–)=3.09(19) b andB(M1)/B(E2) ratios, deduced from the existing -ray spectroscopic data, have been used to derive shape parameters for the h_11/2 band based on this isomer. The present results are consistent with a quadrupole deformation=0.22(1),=0⁰±10⁰.
