A microfluidic microarray that is created in the double spiral format has produced a greater density of probes than in our previous report. Using this double-spiral format together with centrifugal pumping for liquid delivery, 384 x 384 hybridization assays have been performed on one circular disk at one time, at the intersections between the spiral channels and spiral probe lines. Each sample ...

In this study, a numerical approach was carried out to analyze the effects of different geometries microchannel heat sinks on forced convective transfer in single-phase flow. The simulations were performed using commercially available software COMSOLMultiphysics 5.6® (Burlington, MA, USA) and its results compared with those obtained from experimental tests polydimethylsiloxane (PDMS). Distilled...

Abstract Powder-bed fusion additive manufacturing technology makes it possible to produce parts with complicated geometry and high accuracy. However, dimensional deviation caused by powder overmelting dross formation is still a challenge for thin channels. In this study, the origins of printed channels were analyzed concept called “melting cell” proposed describe quantify geometric error. Based...

A low-complexity time-domain channel estimation technique for OFDM systems is proposed. It uses a training symbol (preamble) to estimate the channel impulse response (CIR) via circular cross-correlation. An efficient CIR search window technique is also proposed to optimise the accuracy of synchronisation and channel estimation. Simulation results in quasi-static channels show that the proposed ...

An open-framework indium selenide, [C7H10N][In9Se14], has been prepared under solvothermal conditions in the presence of 3,5-dimethylpyridine and characterized by single-crystal X-ray diffraction, thermogravimetry, elemental analysis, Fourier tranform IR spectroscopy, and UV-vis diffuse reflectance. The crystal structure of [C7H10N][In9Se14] contains an unusual building unit, in which corner- a...

Single-file diffusion, prevalent in many processes, refers to the restricted motion of interacting particles in narrow micropores with the mutual passage excluded. A single-filing system was developed by confining colloidal spheres in one-dimensional circular channels of micrometer scale. Optical video microscopy study shows evidence that the particle self-diffusion is non-Fickian for long peri...

In this research, the effects of different channel cross-section shapes on flow, heat transfer and pyrolysis characteristics n-decane were analyzed compared based CFD simulations. The interactions between cracking, flow field in a circular tube rectangular studied. results showed that mean pressure drop is 1.18 times as high with due to its smaller equivalent diameter. maximum value chemical si...
