A new colloidal stabilization mechanism, known as nanoparticle "haloing" (Tohver, V.; Smay, J. E.; Braem, A.; Braun, P. V.; Lewis, J. A. Proc. Natl. Acad. Sci. U.S.A. 2001, 98, (16), 8950-8954), has been predicted theoretically and inferred experimentally in microsphere-nanoparticle mixtures that possess high charge and size asymmetry. The term "halo" implies the existence of a nonzero separati...

Low-intensity magnetic separators are widely used in the research works and the industry. Advancement in the magnetic separation techniques has led to an expansion in the application of this method in different fields such as enrichment of magnetic mineral, wastewater treatment, and medicine transfer in the human body. In the mineral processing industry, the main application of wet magnetic sep...

Angle-of-arrival estimation is a widely used localisation method. However, multipath propagation leads to decreased performance. In this paper an expression for the CramerRao lower bound for angle-of-arrival estimation with a known transmitted signal in a two path environment is derived. The influence of array structure on the achievable accuracy and the capability of signal separation is inves...

In the title compound, C(16)H(13)BrFN(3)O(2)S, the dihedral angle between the aromatic rings is 2.55 (19)° and the C=N-N=C torsion angle is 178.9 (3)°. The conformation of the thia-zine ring is an envelope, with the S atom displaced by -0.811 (3) Å from the mean plane of the other five atoms (r.m.s. deviation = 0.042 Å). In the crystal, C-H⋯O inter-actions link the mol-ecules and weak aromatic ...

In the title compound, C(16)H(13)BrN(4)O(4)S, the dihedral angle between the aromatic rings is 4.1 (2)° and the C=N-N=C torsion angle is 175.5 (3)°. The nitro group is almost coplanar with the benzene ring to which it is attached [dihedral angle = 2.9 (7)°]. The thia-zine ring has an S-envelope conformation with the S atom displaced by 0.819 (3) Å from the mean plane of the other five atoms (r....

Iridoschisis is a rare condition that consists of the separation of the anterior mesodermic layer of the iris. In more than two-thirds of cases it is associated with glaucoma. We report the case of an 80-year-old patient who had bilateral iridoschisis and presented with acute angle-closure glaucoma. The patient was free from a history of ocular trauma or of heritable ocular disease. Chronic ope...

A method is presented for determining the dynamic contact angle at the three-phase contact between a solid, a liquid, and a vapor under an applied force, using molecular simulation. The method is demonstrated using a Lennard-Jones fluid in contact with a cylindrical shell of the fcc Lennard-Jones solid. Advancing and receding contact angles and the contact angle hysteresis are reported for the ...

This paper presents an exact analytical solution for two-dimensional conductive heat transfer in spherical composite pressure vessels .The vessels are in spherical shape and fibers are winded in circumferential direction. The analytical solution is obtained under the general boundary conditions which consist of convection, conduction and radiation inside/outside of vessel. The heat transfer equ...

Nanofiltration is increasingly gaining attention in many separation and treatment processes such as water softening, color removal and separation of medicines. Nanofiltration membranes are often negatively charged, displaying separation characteristics in the intermediate range between reverse osmosis and ultrafiltration. In this research, a novel nanofiltration membrane prepared with poly(amid...
