Microfluidic-based biochips are soon revolutionizing clinical diagnostics and many biochemical laboratory procedures due to their advantages of automation, cost reduction, portability, and efficiency [18]. Conventional technology depends on the manipulation of continuous liquid flow through microfabricated channels. However, actuation of flow is implemented with external assistance of micro-pum...
dispersive liquid-liquid microextraction method (dllme) combined with high-performance liquid chromatography-ultraviolet detection (hplc-uv) was used to determine thiamine (b1), nicotinamide (b3) and pyridoxine (b6) in sour cherry juice. this method was rapid, simple and sensitive. separation was accomplished using a c18 column. the optimum chromatographic conditions were found to be: mobile ph...
in this study, we combined ionic liquid-based dispersive liquid liquid micro extraction (il-dllme) with faas for determining the palladium in different real samples at the trace level. 1-hexyl-3-methylimidazolium hexafluorophosphate [hmim][pf6] ionic liquid and 1-(2-pyridylazo) 2-naphthol (pan), were chosen as the extraction solvent and the chelating agent, respectively. the hydrophobic pd–pan ...
Self-organized supramolecular organic nanostructures have potential applications that include molecular electronics, photonics, and precursors for nanoporous catalysts. Accordingly, understanding how self-assembly is controlled by molecular architecture will enable the design of increasingly complex structures. We report a liquid crystal (LC) phase with a tetragonal three-dimensional unit cell ...
This paper presents the details of a novel battery architecture based on superhydrophobic nanostructured materials. Both electrodes of a battery are formed on nanostructured silicon surfaces that are subsequently treated to make them superhydrophobic, effectively separating the liquid electrolyte from the active electrode materials. A phenomenon called electrowetting that promotes electrolyte p...
The paper presents the details of a novel battery architecture based on the superhydrophobic nanostructured materials. In a proposed configuration both electrodes of a battery are formed on the nanostructured silicon surfaces that are subsequently treated to render them superhydrophobic, effectively separating liquid electrolyte from the active electrode material. When battery is activated to p...
A promising approach to the fabrication of materials with nanoscale features is the transfer of liquid-crystalline structure to polymers. However, this has not been achieved in systems with full three-dimensional periodicity. Here we demonstrate the fabrication of self-assembled three-dimensional nanostructures by polymer templating blue phase I, a chiral liquid crystal with cubic symmetry. Blu...
The recent achievement of atomic resolution with dynamic atomic force microscopy (dAFM) [Fukuma et al., Appl. Phys. Lett. 2005, 87, 034101], where quality factors of the oscillating probe are inherently low, challenges some accepted beliefs concerning sensitivity and resolution in dAFM imaging modes. Through analysis and experiment we study the performance metrics for high-resolution imaging wi...
A parallel quaternion-based dissipative particle dynamics (QDPD) program has been developed in Fortran to study the flow properties of complex fluids subject to shear. The parallelization allows for simulations of greater size and complexity and is accomplished with a parallel link-cell spatial (domain) decomposition using MPI. The technique has novel features arising from the DPD formalism, th...
Rumi was not an architect or architectural theorician. However in his Mathnawi, he dealt in architecture, explicitly or implicitly, intentionally or unintentionally. It can be seen in Mathnawi in diferrent levels: when he talks about the built environment in which he used to live when he uses architecture elements and spaces as figure of speech when he borrows an architectural metaphor in talki...
