Xylanase enzymes are group of enzymes that can degrade Xylan present in plants. Xylan lignin and cellulose formed a complex matrix in plants. Lignin imparts colour to cellulose and thus eventually imparts colour to paper and pulp. Xylanase facilitates the removal of lignin from the paper pulp thus improves the brightness of paper....

2-Thiophenecarboxylic acid hydrazide has been treated with benzaldehyde in 1:1 molar ratio at room temperature in the presence of a suitable solvent to yield Schiff base. Then it has been treated with R2SnCl2/R3SnCl in 1:1 molar ratio to synthesize organotin(IV) complexes under reflux conditions....

The work presented concerns the preparation, characterization and biological evaluation of Cu(II) and Zn(II) complexes of Schiff bases derived from amoxycillin, cephalexin, sulphamethoxazole and trimethoprim, and salicylalde-hyde and pyridoxal....

Beauty creams and sun blocks are cosmetic products. The majority of creams and lotions are emulsions. An emulsion can be defined simply as two immiscible fluids in which one liquid is dispersed as fine droplets in the other....
