In this work, nanocomposite (NC) hydrogels based on polyacrylamide/chromium triacetate were prepared at different reaction mixture (gelant) volumes and their crosslinking process and viscoelastic behaviors were studied. The X-ray diffraction (XRD) patterns taken from the NC hydrogels containing laponite nanoparticles did not show any distinct characteristic basal reflection for all of the NC hy...

ABSTRACT In this paper, novel Nanohybrid CuO-Fe3O4/Zeolite nanocomposites (HCFZ NCs) have been synthesized to improve the adsorption capacity and activity for removing the Arsenic and Lead cations from the contaminated water solutions. The nanohybrid 4, 10, and 20 -HCFZ NC samples were investigated by XRD, FT-IR, TEM, FESEM, EDX, and BET. The characterization results of these catalysts confirm...

Ionic liquids (ILs) have the advantages of low cost, eco-friendliness, abundant heteroatoms, excellent solubility, and coordinated ability with metal ions. These features make ILs a suitable precursor for fabricating single-atom catalysts (SACs). Herein, we prepared various single atoms anchored on ultrathin N-doped nanosheets (denoted as Cu1/NC, Fe1/NC, Co1/NC, Ni1/NC, Pd1/NC) by direct pyroly...

Formic acid/choline chloride (F-DES), one of high-efficiency deep eutectic solvents (DES) for lignocellulose pretreatment, has great potential in the production nanocellulose (NC). In this work, integrated preparation cellulose nanocrystals (CNCs) and nanofibrils (CNFs) was developed using F-DES pretreatment following ball milling. Then, properties resultant NC products (F-NC) were comprehensiv...

It has been shown that activated T-cells produce and release both IL-2 and IL- 2 receptors (lL-2R). The rate of IL-2 release is proportional to its cell surface expression and state of cell activation. To clarify the molecular basis of this immunological aberration, we analysed the amount of soluble IL-2R(SIL2-R) by an ELISA technique in 68 patients with Behcet's disease (BD), 28 patient co...

I review some progress made on the problem of calculating electroweak processes of mesons at low energy with the use of an approximation to large-Nc QCD which we call the Minimal Hadronic Approximation. An update of results for the matrix elements of the electroweak penguin operators Q 7 and Q 8 is also given.

We investigate nonfactorizable contributions to charm meson decays in D → K̄π/ K̄ρ /K̄π / K̄a1 / K̄ρ modes. Obtaining the contributions from spectator-quark diagrams for Nc = 3, we determine nonfactorizable isospin 1/2 and 3/2 amplitudes required to explain the data for these modes. We observe that ratio of these amplitudes seem to follow a universal value.
