Bend Test of Concrete Power Poles

Concrete beams should be resistant against the influence of corrosive agents, environmental degradation, and mechanical forces. In this article, the effect of two different concrete mixing designs is investigated against the pole’s bend strength behavior.

Study: Radiation Can Slow Corrosion of Reactor Alloys

A team of researchers at the Massachusetts Institute of Technology and the Lawrence Berkeley National Laboratory have found that exposure to radiation can improve the resistance of certain alloys that could be used in fission or fusion reactors.

Sunflower Oil-Based Inhibitors Slow Corrosion in Offshore Arctic Conditions

After finding high efficiency in laboratory tests, scientists are intending to apply new bio-based corrosion inhibitors—developed on the basis of sunflower oil—in harsh Arctic conditions.

Moisture Drainage and Stand-Offs Impact on Insulation Wetting

Patterns of moisture trapping underneath insulation were visualized using moisture detection imaging, and a contact-free insulation system with low-point drains achieved maximum drainage efficiency (97%) and the least trapping.

Researchers Seek Better Fabrication Techniques for pH-Responsive Microcapsules

The new technique developed by University of Illinois researchers can potentially be used to make microcapsules that respond to changes in pH, which are useful for applications such as anticorrosion coatings.
