Studies on the Adsorption Behavior of 152+154Eu (III) on Synthesized Graphene Oxide
Journal of Scientific Research in Science, 2020 Graphene oxide (GO) Samples are locally synthesized for use in sorption and radionuclides removal studies of 152+154Eu (III). The samples were characterized by FT-IR, X-ray diffraction (XRD) and electron scanning microscopy (SEM). These samples are used

Axial Couplings on the World-Line [PDF]
, 1995 We construct a world-line representation for the fermionic one-loop effective action with axial and also vector, scalar, and pseudo-scalar couplings. We use this expression to compute a few selected scattering amplitudes.

Cr(VI) Sorption from Aqueous Solution: A Review
Applied Sciences, 2020 Hexavalent chromium (Cr(VI)) in water systems is a major hazard for living organisms, including humans. The most popular technology currently used to remove Cr(VI) from polluted water is sorption for its effectiveness, ease of use, low cost and ...

Imaginary Chemical Potential Approach for the Pseudo-Critical Line in the QCD Phase Diagram with Clover-Improved Wilson Fermions [PDF]
, 2011 The QCD phase diagram is studied in the lattice QCD simulation with the imaginary chemical potential approach. We employ a clover-improved Wilson fermion action of two-flavors and a renormalization-group improved gauge action, and perform the simulation ...

Predictor Design of a Novel Grey Model PGM21 Using Pseudo Second-Order Information
JSME International Journal Series C, 2006 A novel grey model, called pseudo-GM(2,1) or PGM21 for simplicity, is developed to improve the prediction accuracy for a non-monotone sequence by modifying the GM(1,1) model with a remedial term. Since the remedial term consists of two development coefficients, it can be treated as a kind of second-order information, called the pseudo second-order ...
