Bone like hydroxyapatite (nHAp) was synthesized via an in situ biomimetic process in presence of wheat starch. The effect of polymer concentration alteration on the final structure of nHAp was investigated. Formation of the nHAp at room temperature was confirmed by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR). Size and morphology of the nHAp samples were character...

This paper describes the design and implementation of a lowcost portable tabletop to be used in classrooms. This solution enables pen and touch interactions over a projected canvas. Twelve users participated in a user study that gauged the system’s effectiveness to support drawing and moving objects on the surface. Additionally, a stress test to evaluate users’ identification was conducted. Res...

Fit the nozzle of a 4 oz. or 8 oz. glass syringe into a Jacques' catheter of the required size and charge the catheter and the syringe with weak iodine solution. Introduce the catheter into the bottom of the cavity to be drained. Inject the solution slowly into it and draw the contents of the cavity into the syringe. Take the syringe out, leaving the catheter still in the cavity, and throw out ...

A microbial electrolysis cell (MEC)-forward osmosis (FO) system was previously reported for recovering ammonium and water from synthetic solutions, and here it has been advanced with treating landfill leachate. In the MEC, 65.7±9.1% of ammonium could be recovered in the presence of cathode aeration. Without aeration, the MEC could remove 54.1±10.9% of ammonium from the leachate, but little ammo...

This paper highlights the importance of validating Computational Fluid Dynamics (CFD) results from a configuration as close as possible to the subject of our research and application. The validation allows us to optimize the choice of various CFD modeling parameters such as gas flow, grid resolution and solution methodology. The validation is based on comparison between our simulated results an...

Assembling inorganic nanomaterials on graphene is of interest in the development of nanodevices and nanocomposite materials, and the ability to align such inorganic nanomaterials on the graphene surface is expected to lead to improved functionalities, as has previously been demonstrated with organic nanomaterials epitaxially aligned on graphitic surfaces. However, because graphene is chemically...
