magnesium and its alloys are light, biodegradable, biocompatible metals that have promising applications as biomaterials. magnesium is potentially useful for orthopedic and cardiovascular applications. however, the corrosion rate of this metal is so high that its degradation occurs before the end of the healing process. one of the ways to improve the corrosion rate is to compose it’s with ceram...

Nanotechnology can be used to produce slow-release fertilizers. Zeolite and crab shells are materials that as fertilizer encapsulation. This study aimed compare the effects of nano zeolite for encapsulation nitrogen- potassium fertilizers tested on Entisols Inceptisols soil growth yield shallots. The research method a completely randomized design with three factors. factors were type (Entisol I...

Nano-zeolite is an innovative class of materials that received recognition for its potential use in water and tertiary wastewater treatment. These applications include ion-exchange/sorption, photo-degradation, membrane separation. The aim this work to summarize analyze the current knowledge about utilization nano-zeolite these applications, identify gaps field, highlight challenges face wide sc...

Nickel doped TiO2nano particles (1% w/w) were prepared and immobilized on NaX zeolite and after characterization by X-ray diffraction and scanning electron microscopy used as photo catalyts for degradation of orange G. The X-ray diffraction patterns show that the supported TiO2 are crystallized in anatase form and the intensity of the zeolite peaks decreases with the incre...

background: natural organic compounds are known as precursors in the formation of disinfection byproducts. the aim of this study was to evaluate of effect of modified cationic surfactant nano zeolite in the removal of humic acid (ha) from water. materials and methods: nano zeolite (clinoptilolite) was modified by cationic surfactant solution hexadecyltrimethylammonium bromide (hdtma-br), in dos...

in order to investigate the gas separation ability of a column packed with nanozeolitic material, nano nay zeolite was synthesized and granulated. these uniform granules packed in a chromatographic column were utilized for separation of xe and kr under various operating conditions. with regards to the response peaks obtained from trace injections of xe and kr into the column, the first and seco...

The unique properties of microporous zeolites, including ion-exchange properties, adsorption, molecular sieving, catalysis, conductivity have been exploited in improving the performance of gas sensors. Zeolites have been employed as physical and chemical filters to improve the sensitivity and selectivity of gas sensors. In addition, direct interaction of gas molecules with the extraframework ca...

An experimental study conducted to evaluate the hardened and durability characteristics of ternary blended concrete containing Nano-Silica Zeolite along with steel fibers act as micro- reinforcement has been presented in this paper. were included different dosages optimum combination above two materials (Nano-Silica -1% Zeolite- 10%) obtained through trails from viewpoint workability strength. ...

We demonstrate a technique to determine the Van der Waals radius of iodine atoms using Raman spectroscopy. The iodine diatomic molecules are diffused into the nano-scale channels of a zeolite single crystal. We found their polarized Raman spectroscopy, which corresponds to iodine molecule's vibrational motion along the direction of molecular axis, is significantly modified by the interaction be...
