Auxetic material structures exhibit a negative Poisson ratio. The structure expands in the axial and transverse directions under tensile loading vice versa compression loading. Many fabricated designs for auxetic materials exist such as re-entrant hexagonal, chiral, arrowhead geometries. This paper studies unit cell of hexagonal geometry to understand how changing internal angle fillet radius a...

Background and purpose: Autologous hematopoietic stem cell transplantation may be one of the best treatment options for some patients with hematological malignancies. The process of stem cell homing in the bone marrow and the production and proliferation of denovo cell populations is called engraftment and could be considered as one of the key factors in the success of stem cell transplantation...

the complex of ce(iii), [ ce (phensc) (h 0) ] (c10 ) , was synthesized using the phensc, a hexadentate ligand,2,9-diformyl-1,lo- phenanthroline bis (semicarbazone), and characterized by x-ray diffraction. the cerium atom has an unusual coordination number of ten involving six donor atoms of the planar ligand in the equatorial plane and four oxygen atoms from four axial water molecules. the comp...

Background and Objective: The role of mast cells in carcinogenesis is improved in many malignant neoplasms but there are scanty literature which show the role of these cells in pathogenesis of progression of dysplastic lesion to invasive squamous cell carcinoma (SCC). The aim of this study was comparison of mast cell density between squamous cell carcinoma and dysplastic laryngeal mucosa to inv...

The 2-(methylamino) pyridine, L, reacts with CuCl in THF to give hexameric copper (I) complex, [CuCl(L)]6. The molecular structure has been determined by using single-crystal X-ray diffraction method. The complex crustallizes in the monoclinic space group P21/n with four molecules per unit cell. The unit cell dimensions are a = 8.3495 (15), b = 15.622 (6), and c = 17.0...

In this work, the structural and magnetic properties of LaMn1-xCoxO3 (x = 0.00, 0.25, 0.50, 0.75, 1.00) are investigated. The structural characterization of compounds by X-ray powder diffraction is evidence for a rhombohedral structure (R -3c space group). Much less increase of the unit cell volume suggests that Co enters in lattice as Co+2 for x ≤ 0.5 while much more decrease of the unit cell ...

This paper proposes a new sub-threshold low power 9T static random-access memory (SRAM) cell compatible with bit interleaving structure in which the effective sizing adjustment of access transistors in write mode is provided  by isolating writing and reading paths. In the proposed cell, we consider a weak inverter to make better write mode operation. Moreover applying boosted word line feature ...
