The utilization of powdered photocatalysts can cause problems such as agglomeration and difficulty in separation conventional applications. In this work, deposition photocatalyst particles on a co-polymeric network was suggested to solve issue. For purpose, ferrite type perovskite BiFeO3 were immobilized the sulphonated polystyrene-divinyl benzene seeds via facile impregnation process heterostr...

We propose a method to enhance the fuel cell efficiency with the simultaneous removal of toxic heavy metal ions. Carbon monoxide (CO), an intermediate of methanol oxidation that is primarily responsible for Pt catalyst deactivation, can be used as an in-situ reducing agent for hexavalent chromium (Cr (VI)) with reactivating the CO-poisoned Pt catalyst. Using electro-oxidation measurements, the ...

A number of WC-Co cemented carbides with 6–12 wt. % Co were machined and surface finished by grinding or Electrical Discharge Machining (EDM). EDM was executed in deionised water through several consecutive gradually finer steps. Correlations between Material Removal Rate (MRR), surface finish and EDM parameters were derived. The quality and integrity of surface finishes were analysed by Scanni...

objective: in this study, we sought to better understand the immunoregulatory function of stem cells derived from human exfoliated deciduous teeth (shed). we studied the role of the interferon gamma (ifn-γ)-indoleamine 2,3-dioxygenase (ido)-axis in immunoregulation of shed compared to bone marrow derived mesenchymal stem cells (bmmscs) under the same conditions. materials and methods: in this c...

in the present investigation the biosorption potential of rosa gruss an teplitz (red rose) waste biomass (rrwb) for the removal of pb(ii) and co(ii) from aqueous solutions was studied. the effect of different process parameters such as ph, biosorbent dose, biosorbent size, temperature, contact time, initial metal concentration and pretreatments on the biosorption capacity of this waste biomass ...

Novel nitrogen-rich mesoporous carbon nanospheres (NMCN) with high surface area and ordered pore geometry are prepared via a facile pathway for efficient CO 2 capture contaminant removal applications.

Diamond coating of tungsten carbide-cobalt (WC-Co) cemented carbide tools using chemical vapour deposition (CVD) requires removal the cobalt (Co) binder phase from WC-Co surface in order to improve adhesion. Laser ablation is shown be a promising technique for selective Co, which based on difference melting and boiling temperatures between different phases. However, laser with conventional nano...
