The knowledge of moisture transport in porous building materials and components is crucial to predict and avoid several pathologies and is essential to increase the durability. It is easy to know the amount of water that, for example, some material absorbs when in contact with water. However, it is very difficult to determine where the […]

Passive air sampling is a preferred method of air sampling for many applications. Traditionally, this method uses activated carbon as the sorbent and samples are analyzed by chemical or thermal desorption. This research explores the use of carbon nanotubes in the form of a buckypaper as a sorbent for passive sampling by comparing the mass […]

Nano-sized CdS has been prepared by aqueous chemical method using glycine as a capping and stabilizing agent. X-ray diffraction (XRD) analysis of as-synthesized material revealed hexagonal wurtzite structure of CdS with average crystallite size 48.1 nm. The observed FTIR spectra support the template role of glycine in controlling the size of CdS nanoparticles. Photo-catalytic efficiency […]

Recently, the introduction of separation membranes is progressing in the field of sewage and industrial wastewater treatment. The treatment methods with membrane separation have many advantages. Firstly, the sedimentation tank has not been required for the sake of gravity sedimentation. It is possible that the reaction tank become compact. Secondly, suspended solids (SS) can be […]
