Insight into the Exemplary Physical Properties of Zn-Based Fluoroperovskite Compounds XZnF (X = Al, Cs, Ga, In) Employing Accurate GGA Approach: A First-Principles Study.

Using the full-potential linearized augmented plane wave (FP-LAPW) method, dependent on density functional theory, the simple cubic ternary fluoroperovskites XZnF (X = Al, Cs, Ga, In) compound properties, including structural, elastic, electronic, and optical, are calculated. To include the effect of exchange and correlation potentials, the generalized gradient approximation is applied for the optimization operation. This is identified, when we are changing the metallic cation specified as "X" when shifting to Al from Cs, the value of the bulk modulus is found to increase, showing the rigidity of a material.

New spectrophotometric methods for the determination of moxifloxacin in pharmaceutical formulations.

Two rapid, simple and sensitive spectrophotometric methods for the quantitative analysis of moxifloxacin (MOX) in pharmaceutical formulations have been described. The first method (A) involves reaction of MOX with 1,2-naphthoquinone-4-sulphonate (NQS) in alkaline medium (pH 11.0) which results in an orange-coloured product exhibiting maximum absorption (lambda(max)) at 411 nm.
