This paper describes a novel and simple method for measuring the physical strength of pharmaceutical pellets prepared by extrusion granulation. Pharmaceutical powders composed of lactose, cornstarch, and microcrystalline cellulose were kneaded with purified water and dry binder (hydroxypropylcellulose), then extruded through a dome-type extrusion granulator. The physical strength of the dried e...

Solid waste management in developing countries is often unsustainable, relying on uncontrolled disposal in waste dumps. Particular problems arise from the disposal of treatment residues generated by removing arsenic (As) from drinking water because As can be highly mobile and has the potential to leach back to ground and surface waters. This paper reviews the disposal of water treatment wastes ...

Carbon nitride (CNx) is a light-absorber with excellent performance in photocatalytic suspension systems, but the activity of CNx photoelectrodes has remained low. Here, cyanamide-functionalized (NCNCNx) was co-deposited ITO nanoparticles on 1.8 Å thick alumina-coated FTO electrode. Transient absorption spectroscopy and impedance measurements support that acts as conductive binder improves elec...

The Zn-loaded zeolite ZSM-5 is an active and promising catalyst for the conversion of methanol to aromatics with high yield. In this work, we have investigated catalytic performance shaped Zn-ZSM-5/alumina catalysts in reaction at industrially relevant pressures. This has been combined extensive characterization identify Zn species. It clear that introduction leads improved lifetime when carrie...

experimental work was carried out to investigate the influence of impeller speed, granulation time, binder mass and their interactions on granule size distribution, mean size and binder content distribution in a conical high shear granulator. it was observed that the response of high shear granulation to changes in process parameters varies significantly from one operating condition to another....

This study describes the role of in situ nano SiC whiskers on the strength and density of alumina silicate–SiC-carbonrefractory compounds. The prepared specimens were composed of 65 wt. % chamotte as alumina silicatecompound, 15 wt. % SiC-containing material regenerates and 10 wt. % fine coke and 10 wt. % liquid resole asbinder. Different values of additives (such as silicon a...
