Microstructure and Wear Characteristics of Al-4.5Cu-5Pb Alloy

引用

Journal of Materials Science & Technology 1998年第2期14卷 125-131页

作者： om Prakas Pandey(School of Basic and Applied Sciences, Thapar Institute of Engineering & Technology, Patiala-147001, India) School of Basic and Applied Sciences Thapar Institute of Engineering and Technology Patiala-147001 India

Al-4. 5Cu-5Pb alloy was prepared by sand and chill casting. The same alloy was also spray deposited at a gas pressure of 1.6 MPa. The microstructural features exhibit a coarse to fine dendritic morphology for sand and chill cast alloys. Equiaxed grains were observed for spray formed alloys. Wear testing employing a pin-on-disc type set-up, reveals considerably lower wear of spray deposited alloy compared to that of chill and sand cast alloys. The morphological features of wear track on specimen and debris indicated a mixed oxidative-cum-adhesive wear mechanisms for these alloys tested in the present investigation.

Synthesis of Schiff bases of naphtha[1,2-d]thiazol-2-amine and metal complexes of 2-(2'-hydroxy)benzylideneaminonaphthothiazole as potential antimicrobial agents

引用

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2007年第6期8卷 446-452页

作者： AZAM Faizul SINGH Satendra KHOKHRA Sukhbir Lal PRAKASH om Department of Pharmaceutical Sciences Kurukshetra University Kurukshetra Haryana 136119 India Faculty of Pharmacy Seventh of October University P.O. Box 2909 Misurata Libya B. R. Ambedkar Center for Biomedical Research University of Delhi Delhi 110007 India Dr. Department of Pharmaceutical Sciences Kurukshetra University Kurukshetra Haryana 136119 India

Objective： A series of 2-benzylideneaminonaphthothiazoles were designed and synthesized incorporating the lipophilic naphthalene ring to render them more capable of penetrating various biomembranes. Methods： Schiff bases were synthesized by the reaction of naphtha[1,2-d]thiazol-2-amine with various substituted aromatic aldehydes. 2-（2＇-Hydroxy）ben- zylideneaminonaphthothiazole was converted to its Co（Ⅱ）, Ni（Ⅱ） and Cu（Ⅱ） metal complexes upon treatment with metal salts in ethanol. All the compounds were evaluated for their antibacterial activities by paper disc diffusion method with Gram positive Staphylococcus aureus and Staphylococcus epidermidis and Gram negative Escherichia coli and Pseudomonas aeruginosa bacteria. The minimum inhibitory concentrations of all the Schiff bases and metal complexes were determined by agar streak dilution method. Results： All the compounds moderately inhibited the growth of Cram positive and Gram negative bacteria. In the present study among all Schiff bases 2-（2＇-hydroxy）benzylideneaminonaphthothiazole showed maximum inhibitory activity and among metal complexes Cu（Ⅱ） metal complex was found to be most potent. Conclusion： The results obtained validate the hypothesis that Schiff bases having substitution with halogens, hydroxyl group and nitro group at phenyl ring are required for the antibacterial activity while methoxy group at different positions in the aromatic ring has minimal role in the inhibitory activity. The results also indicated that the metal complexes are better antibacterial agents as compared to the Schiff bases.
