With the increase of energy price, the retrofitting of existing buildings with innovative insulation materials remains a key issue. Although a variety of insulation materials there is always a need for the development of new materials with improved thermophysical properties and low cost. Inorganic polymer materials are promising from this point of view. They are incombustible combining excellent physical and thermal properties with low production cost and significant environmental benefits. In t...

Diclofenac (DCF) is a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain in joint-related diseases. It is not completely metabolized after consumption and cannot be easily removed using conventional wastewater treatment. DCF has been detected in water bodies and may pose chronic effects on the endocrines of living organisms even at low-level exposure. Heterogeneous photocatalysis provides an alternative and efficient method of degrading DCF. In this study, the photocatalytic remov...

In the current study, pristine multiwalled carbon nanotubes (p-MWCNTs) were functionalized by HNO 3 for introducing carboxyl functional group on the MWCNTs surface by which hydroxyapatite (HAP) molecules were grafted onto the surface of functionalized multiwalled carbon nanotubes (f-MWCNTs) with strong interfacial bonding. HAP-fMWCNTs-Cobalt ferrite composites were synthesized successfully by the homogenous mixture method. XRD analysis revealed that crystalline peaks of the HAP-f-MWCNT...

Vinasseisa liquid is produced during the process of fermentation and distillation of molasses for the production of ethanol. This paper studies the conversion of vinasse into valuable materials using laser, and the characterization of the provided products. For this purpose, vinasse sample was dried and combusted for 30 seconds using Nd: YAG laser with wavelength 1064 nm at output power 60 W continuous mode. The product of this process was characterized by an X-ray diffractometer (XRD), Fourier ...

In recent years, anisotropic wetting surfaces have attracted wide scientific attention for both fundamental research and practical applications. Directional transportation of droplets, as an efficient method to conduct droplet motion, has attracted great interest in research and industrial fields. Nevertheless, the great challenges in its application focus on these aspects such as sample conservation, velocity, distance, precision and driving force. Very recently, some research highlights were p...

Poor combination of input process parameters has resulted in an innumerable amount of weld failure due to its negative influence on the microstructural and mechanical properties of the welded joints. To improve the welded joint, it is imperative that the material toughness be optimized. The aim of this study is to predict and enhance the toughness of mild steel welded joint using Response Surface Methodology (RSM). 10 mm mild steel plate was cut into 200 piece coupons measuring 27.5 × 10 × 10 mm...

Transportation of Dangerous goods by road may have serious consequences in case of an accident occur. The consequences of a road accident of a heavy goods vehicle carrying dangerous goods may affect not only the truck driver but also the nearby population present. Routing selection is a complicated issue influenced from a number of parameters that may vary during the day, a week or a month. The purpose of the research is to develop a preliminary tool concerning the Transportation of Dangerous Go...

In this studio and laboratory research study, the suitability of several glazes for use on the earthenware clays used by local potters in the internal provinces of Oman was investigated. The aim was to develop suitable, economic glazes from local materials for use with Omani earthenware clays that could form an adequate adhesive bond with the clay surface and be used in ceramics decoration in local educational institutions. In particular, the experiments in this study mainly evaluated the use of...

In this paper, we have discussed the coloration mechanism based on visible absorption spectra testing by selecting three typical samples of Luodian jade with white, pallor and cyan. The attribution analysis of absorption spectra showed that absorption of Luodian jade in visible light mainly includes charge transfer spectrum of Fe2 → Ti4 (at 490 nm - 500 nm) and Fe2 → Fe3 (at 523 nm - 536 nm, 646 nm - 657 nm), electron transition 6A1 → 4T2 (4G) of Fe3 (at 615 nm - 632 nm, 685 nm - 694 nm) an...

Mg2 and bovine serum albumin (BSA) Langmuir monolayers were used as effective crystal nucleation and growth modifiers and template to control the crystallization of CaCO3. The polymorph and morphology of crystals were characterized using scanning electron microscopy (SEM), and X-ray diffraction (XRD). The results demonstrated that various morphologies such as abacus-bead-like particles, spherical-shaped particles, wood block-like particle ...
