The aim of this study was to investigate the feasibility of using nonmetallic printed circuit board (PCB) waste as filler in recycled HDPE (rHDPE) in production of rHDPE/PCB composites. Maleic anhydride modified linear low-density polyethylene (MAPE) was used as compatibilizer. In particular, the effects of nonmetallic PCB and MAPE on mechanical properties of the composites were assessed throug...

Density matrix perturbation theory [Niklasson and Challacombe, Phys. Rev. Lett. 92, 193001 (2004)] is generalized to canonical (NVT) free-energy ensembles in tight-binding, Hartree-Fock, or Kohn-Sham density-functional theory. The canonical density matrix perturbation theory can be used to calculate temperature-dependent response properties from the coupled perturbed self-consistent field equat...

In this paper, a feasibility study was conducted to test whether capacitive sensors could be used to detect water and produce a graph with the minimal amount of equipment and materials. A lab was setup to conduct experiments and retrieve raw data. The data is then processed using a back projection algorithm in an attempt to produce an image of the water from within a nonmetallic pipe. The image...

Growing demand of invisible braces by esthetically conscious patients has led to remarkable inventions in materials for esthetic labial archwires. Archwires with excellent optical clarity and mechanical properties comparable to conventional archwires have been manufactured by almost all the leading companies of orthodontic products in the past two decades, but their clinical use is still limite...

Introduction and Background: Ceramics are inorganic, nonmetallic materials, such as alumina, beryllia, or glassceramic, whose final characteristics are produced by subjection to high temperatures. Nanomaterials is a rapidly growing area of ceramics [1-3] and can be classified into the following categories: Nano-particles submicron or ultra micron size particles; Nano-fibers – nanometer (nm) siz...

A new general reflectance model for computer graphics is presented.The model is based on physical optics and describes specular, di-rectional diffuse, and uniform diffuse reflection by a surface. Thereflected light pattern depends on wavelength, incidence angle, twosurface roughness parameters. and surface refractive index. The for-mulation is self consistent in terms of...

Filtration is the most cost effective method to purify aluminum. In this paper, filtration experiments have been carried out using both AlF3 slurry coated, and uncoated Al2O3 ceramic foam filter (CFF) to study the removal of both nonmetallic inclusions and impurity elements. The results showed that the 30 ppi CFF removed up to 85% inclusions from aluminum. The contributing mechanisms for the re...

We have carried out molecular-dynamics simulations for nonmetallic fluid mercury in liquid and vapour phases using a Lennard-Jones type effective potential and shown that the structure factors S(Q) and the dynamic structure factors S(Q,ω ) of nonmetallic fluid mercury obtained by our MD simulations are in good agreement with recent x-ray diffraction and inelastic x-ray scattering experiments. W...
