چکیده
Physics and Society is a quarterly newsletter of the Forum on Physics and Society, a division of the American Physical Society. It is distributed free to members of the Forum and to physics libraries upon request Physics and Society presents articles and letters on the relations of physics and the physics community to government and society, on the social responsibilities of scientists, and on the scientific and economic health of the phy sics commWlity. It presents news of the Forum and of the American Physical Society (335 East 45th Street, New YorIc. NY 10017) and provides a medium for Forum members to exchange ideas. Opinions expressed are those of the author only and do not necessarily reflect the views ofthe APS or of the Forum. Contributions should be sent to the Editor. Art Hobson.

The comparison synthesis of CuNiO2 nanoparticles prepared by sol-gel auto-combu on, microwave and co-precipitation techniques
The CuNiCA nanopanicles have been synthesized by sol-gel auto-combusson. microwave and co-precipitationtechniques. Then, the results of the three techniques were compared. In the vol-ael auto-combustion synthesiswas used glycine as a fuel. At first, sol was prepared. Then, gel was achieved from drying so'. The prepared gelwas burnt at 350°C. In the noicrowavc technique, gel was prepared. Then, ...

متن کاملPhoto catalytic property of ZnO and Mn-ZnO nanoparticles in removal of Cibacet Turquoise blue G from aquatic solution
ZnO and Mn-ZnO nano powders were prepared by the sol-gel auto combustion method. The products were characterized by X-ray diffraction (XRD), energy dispersive analysis of X-ray (EDX) and scanning electron microscopy (SEM). Structural and morphological properties of nano particles were investigated and the average crystalline size of ZnO and Mn-doped ZnO was obtained 44 and 51 nm, respectively. ...
