The structure of bio-carriers is one of the key operational characteristics of a biofilm reactor. The goal of this study is to develop a series of novel fullerene-type bio-carriers using the three-dimensional printing (3DP) technique. 3DP can fabricate bio-carriers with more specialized structures compared with traditional fabrication processes. In this research, three types of fullerene-type b...
ABSTRACRT: Over a period of time a number of biomaterials have been developed and are used for hard tissue and joint replacement those are Stainless steel (SS-316L), Co-Cr alloy, Titanium (Ti) and its alloy, ceramics and Polymer especially Ultra High Molecular Weight Polyethylene (UHMWPE) and Alumina (Al2O3). These biomaterials for its suitable mechanical properties, nontoxic behavior, and bio-...
since its advent in 1867,the arabic novel has been under the influence of two factors. one factor is longing for the past, the other one is infatuation with the west and submission to its hegemony. in early 20th century, some novels were written in response to public taste and arab culture. this novel is considered by critics of fiction to be a turning point in the path of arabic fiction. at th...
In the area of waste water treatment, membrane processes are often used in combination with other processes to treat very complex effluents which have often an important load of organic substances and salt. The membrane process would enhance the water treaded quality in order to water reuse [1]. Membrane can be in polymer or in inorganic material. Ceramic membranes have several advantages compa...
A novel negative, inorganic polymer photoresist was demonstrated to be suitable for simple and direct fabrication of tribological SiCN-based ceramic microstructures via UV photolithography and subsequent pyrolysis at 800 degrees C.
In 1776 ceramic material was first suggested for a dental application by the French chemist Alexis Duchateau who worked in collaboration with the dentist Dubois de Chemant to produce the first complete denture. The material used was a mixture of potash feldspar (K2O.Al2O3.6SiO2, 70-80%), quartz (SiO2, 10-30%) and kaolin (Al2O3.Si02.2H2O, 0-3%) [1]. Since then the potential of the material was u...
