High Temperature Effectiveness of Ginger Extract as Green Inhibitor for Corrosion in Mild Steel

open access: yesNUST Journal of Engineering Sciences, 2019
Corrosion is one of the major problems of mild steels in acidic medium. This can be minimized by the application of corrosion inhibitors, however; the most of inhibitors are toxic in nature. Therefore inhibitors from green sources are highly desirable to

Physics Opportunities with Polarized e- and e+ Beams at TESLA [PDF]

open access: yes, 2001
Beam polarization at e+ e- linear colliders will be a powerful tool for high precision analyses. Often it is assumed that the full information from polarization effects is provided by polarization of the electron beam and no further information can be ...
