Microfluidic devices and biochips offer miniaturized laboratories for the separation, reaction, and analysis of biochemical materials with high sensitivity and low reagent consumption. The integration of functional or biomimetic elements further functionalizes microfluidic devices for more complex biological studies. The recently proposed ship-in-a-bottle integration based on laser direct writi...
Here we illustrate the free search for the optimal geometry of flow channel cross-sections that meet two objectives simultaneously: reduced resistances to heat transfer and fluid flow. The element cross section and the wall material are fixed, while the shape of the fluid flow opening, or the wetted perimeter is free to vary. Two element cross sections are considered, square and equilateral tri...
Three-dimensional phase-field simulations are employed to investigate rod-type eutectic growth morphologies in confined geometry. Distinct steady-state solutions are found to depend on this confinement effect with the rod array basis vectors and their included angle (α) changing to accommodate the geometrical constraint. Specific morphologies are observed, including rods of circular cross secti...
One-dimensional (1-D) supramolecular self-assembly offers a powerful strategy to achieve long-range unidirectional ordering of organic semiconducting materials via noncovalent interactions. Using a hierarchical assembly, electronic and optoelectronic materials can be constructed for applications including organic conducting nanowires, organic field-effect transistors (OFETs), and organic light-...
Abstract The manufacturing process and mechanical instability of high performance magnetocaloric materials hamper the implementation novel geometries for active magnetic regenerators. In this work, La(Fe,Si,Mn)13Hy is shaped into a regenerator with triangular microchannels hydraulic diameter 200–300 μm using that results in highly stable structure. characterized regards to heat transfer, resist...
A high performance two dimensional scalable parallel algorithm for solving sparse triangular systems
Solving a system of equations of the form Tx = y, where T is a sparse triangular matrix, is required after the factorization phase in the direct methods of solving systems of linear equations. A few parallel formulations have been proposed recently. The common belief in parallelizing this problem is that the parallel formulation utilizing a two dimensional distribution of T is unscalable. In th...
This paper introduces triangular wavelets, which are two-dimensional nonseparable biorthogonal wavelets defined on the regular triangular lattice. The construction that we propose is aimed at preserving isotropy, and a simple nonseparable extension of one-dimensional interpolating wavelets followed by a straightforward generalization. Resulting three oriented high-pass filters are symmetrically...
Magnetic property of antiferromagnets with two-dimensional distorted triangular lattice structures, β′-Me4P[Pd(dmit)2]2 and β′-Et2Me2P[Pd(dmit)2]2, was investigated by the muon spin relaxation method. Enhancement of the muon spin depolarization associated with the critical slow-down effect suggests that the spin dynamics due to the twoand three-dimensional magnetic correlations reflects the dev...
