XANES spectra of forsterite in crystal, surface, and amorphous states

open access: yesAIP Advances, 2018
The electronic structures of forsterite and its amorphous state were investigated using soft X-ray absorption near-edge structure (XANES) analysis at the Mg, Si, and O K-edges.

Controlled and localized delivery of c-myc AS-ODN to cells by 3-aminopropyl-trimethoxylsilane modified SBA-15 mesoporous silica

open access: yesAIP Advances, 2018
SBA-15 mesoporous silicate was synthesized and functionalized with 3-aminopropyl organic groups through a post-synthesis method. The materials were characterized consecutively by powder X-ray diffraction (XRD), N2 adsorption/desorption analysis and solid-

A note on Pretzelosity TMD parton distribution

open access: yesPhysics Letters B, 2019
We show that the transverse-momentum-dependent parton distribution, called as Pretzelosity function, is zero at any order in perturbation theory of QCD for a single massless quark state.

Microwave absorbing efficiency of Al matrix composite reinforced with nano-Ni/SiC particles

open access: yesResults in Physics, 2019
An Al/Ni-SiC composite was prepared. Nickel at 10 wt% along with SiC particles was used as a reinforcement for the Al matrix. Two different techniques were used for the fabrication process: coating of SiC particles with nano-nickel particles via the ...

Investigating saturation effects in ultraperipheral collisions at the LHC with the color dipole model

open access: yesPhysics Letters B, 2020
We investigate saturation effects in ep scattering as well as in ultraperipheral pA and AA collisions at small x with four variants of the impact parameter dependent color dipole model: with and without gluon saturation and with and without a novel ...

Effect of various parameters on the microstructure and magnetic properties of sintered Sr-hexaferrite

open access: yesResults in Physics, 2019
Sr-hexaferrite powders with Fe/Sr molar ratio of 11 was synthesized via conventional ceramic route. Powders were milled for 5–25 h, then pressed to make green compacts by applying a pressure of 100–400 MPa.

Role of the Soffer bound in determination of transversity and the tensor charge

open access: yesPhysics Letters B, 2020
The transversity and the tensor charge of the nucleon, currently under active investigation experimentally and theoretically, are fundamental quantities in hadron physics as well as for our comprehension of the nucleon structure. Some tension between the

Martensite-like transition and spin-glass behavior in nanocrystalline Pr0.5Ca0.5MnO3

open access: yesAIP Advances, 2011
We report on isothermal pulsed (20 ms) field magnetization, temperature dependent AC – susceptibility, and the static low magnetic field measurements carried out on 10 nm sized Pr0.5Ca0.5MnO3 nanoparticles (PCMO10).
