Nickel hexacyanoferrate nanoparticles were synthesized and characterized using elemental analysis, thermal analysis, infrared spectroscopy, and X-ray diffraction. A FE-SEM image of the nickel hexacyanoferrate showed that it consists of nearly spherical particles with sizes ranging from 30 to 70 nm. The synthesized material was found to be a heterogeneous catalyst useful for the solvent-free oxidation of benzyl alcohol with H2O2 as an oxidant. A 36% conversion of benzyl alcohol to benzaldehyde was achieved under optimized reaction conditions using specific parameters such as the amount of catalyst, the temperature, the benzyl alcohol to H2O2 molar ratio, and the reaction time.

Acacia nilotica （L.） Delile, commonly known as ＂Babul＂, is reported for its medicinal property since ages. Plant is recognized for its medicinal use in traditional practices. For the study, phytochemicals were extracted as well as identified from four different solvents and their antibacterial property was determined. The fingerprinting was accomplished using HPTLC and the MIC （Minimum Inhibitory Concentration） was elucidated using standard protocols. Two Gram positive （Staphylococcus aureus and Bacillus subtilis） and two Gram negative （Escherichia coli and Pseudomonas aeruginosa） bacteria were selected for the antibacterial screening. The major phytochemicals identified in the extract of the bark of A. nilotica were catechin/epicatechin, ellagic acid and m-digallic acid. Excellent antimicrobial activity was found in chloroform （40 ~tg/mL） and methanol （60 ~g/mL） extracts against Pseudomonas aeruginosa. The chloroform extracts consist of higher number of phytochemicals/bands as compared with other extracts and demonstrated significant antibacterial activity against all the test bacterial species.
