New mesostructured origami silica matrix: a nano-platform for highly retentive and pH-controlled delivery system

open access: yesJournal of Taibah University for Science, 2021
In the present study, stabilizer caged fluorescent rhodamine B mesoporous silica particles with special shapes were prepared. The prepared particles have a pore volume of 1.92 cm3/g and a pore diameter of 12 nm. The abundant hydroxyl functional groups of

Synthesis of NiO nanowalls by thermal treatment of Ni film deposited onto a stainless steel substrate [PDF]

open access: yes, 2008
Two-dimensional nanostructures have a variety of applications due to their large surface areas. In this study, the authors present a simple and convenient method to realize two-dimensional NiO nanowalls by thermal treatment of a Ni thin film deposited ...

Contribution of Twist-3 Multi-Gluon Correlation Functions to Single Spin Asymmetry in Semi-Inclusive Deep Inelastic Scattering

open access: yes, 2010
As a possible source of the single transverse spin asymmetry, we study the contribution from purely gluonic correlation represented by the twist-3 ``three-gluon correlation" functions in the transversely polarized nucleon.

Assessing composition gradients in multifilamentary superconductors by means of magnetometry methods

open access: yes, 2016
We present two magnetometry-based methods suitable for assessing gradients in the critical temperature and hence the composition of multifilamentary superconductors: AC magnetometry and Scanning Hall Probe Microscopy.

Nonstoichiometric doping and Bi antisite defect in single crystal Bi2Se3

open access: yes, 2012
We studied the defects of Bi2Se3 generated from Bridgman growth of stoichiometric and nonstoichiometric self-fluxes. Growth habit, lattice size, and transport properties are strongly affected by the types of defect generated.

Measuring Performance of EDX Systems

open access: yesMicroscopy and Microanalysis, 1998
Abstract There are no “absolutes” in terms of performance and wherever possible, performance measures need to reflect conditions similar to those in the intended application. Unfortunately, measurements are frequently constrained by practical and economic considerations.

Enhancement of Tc by Sr substitution for Ba in Hg-2212 superconductor [PDF]

open access: yes, 2003
The Ba substitution by Sr has been studied in two Hg-2212 series: Hg2(Ba(1-y)Sr(y))2YCu2O8-d and Hg2(Ba(1-y)Sr(y))2(Y0.80Ca0.20)Cu2O8-d. In both series a Tc enhancement of about 40 K is observed when Sr substitutes Ba from y = 0 to y = 1.0.
