The arsenate-intercalated layered double hydroxide (LDH) of Mg and Al is synthesized by coprecipitation. The higher thermodynamic stability and the consequent lower solubility of the unitary arsenates preclude the formation of arsenate-intercalated LDHs of other metals directly from solution. However other M/Al-AsO(4) (M=Co, Ni, Zn) LDHs could be prepared(More)
The LDH of Ni with Fe, having the formula Ni(1-x)Fe(x)(OH)2(A(n-))(x/n)yH2O (A = NO3-, Cl-; x = 0.25, 0.33), scavenges CrO4(2-) ions from solution throughout the concentration range examined (0.00625-0.25 N). The CrO4(2-) uptake capacity is independent of the anion in the starting LDH but is higher when x = 0.25 (3.60 meq g(-1)) as compared to x = 0.33(More)
The iodide-containing layered double hydroxides (LDHs) of Mg and Zn with Al crystallize by the inclusion of extensive positional disorder of I(-) ions in the interlayer region. I(-) ion given its poor charge to size ratio can neither screen effectively the positive charge nor participate in H-bonding with the metal hydroxide layers. Thereby the I(-) ions(More)
A CSTR is an Continuously Stirred Tank Reactor with the main function of agitation and to achieve constant composition. It has an important role in chemical process plants. A CSTR has an higher degree of nonlinearity when compared with other chemical reactors, this is mainly due to the temperature variations that occur because of uncertainity in feed.(More)
In this paper we present an application of robust optimization to capacity planning problems under uncertainty. We present the framework to handle uncertainty and discuss the computational complexity of capacity planning problems under this framework. We show that the formulation is not only intuitive but the computational complexity of a large variety of(More)
A digital readout electronics scheme in CMOS technology is described for integration with micro-electro-mechanical (MEM) sensors on the same chip. The readout circuit is general in nature and can be employed with a variety of analog sensors. The presented scheme in CMOS technology is fully integrable with the multiple sensor outputs either in a chain or an(More)
The proposal of this paper presents a measurementbased routing algorithm to load balance intra domain traffic along multiple paths for multiple multicast sources. Multiple paths are established using application-layer overlaying. The proposed algorithm is able to converge under different network models, where each model reflects a different set of(More)
