Sol‐Gel Coating on CA‐60 Steel Surfaces: A Process for Corrosion Inhibition

Materials and Corrosion, EarlyView.
30% of the steel produced worldwide is used to replace losses due to corrosion. The application of the sol‐gel process to inhibit and delay deterioration appears as a viable methodology for protection against aggressive environments. ABSTRACT The phenomenon of corrosion causes worldwide damage, which is not only economic but also results in the loss of

Crack mitigation in concrete : superabsorbent polymers as key to success? [PDF]

, 2017
Cracking is a major concern in building applications. Cracks may arise from shrinkage, freeze/thawing and/or structural stresses, amongst others. Several solutions can be found but superabsorbent polymers (SAPs) seem to be interesting to counteract these

Recent Developments in Sustainable Composites for Printed Circuit Boards (PCBs): A Review

Macromolecular Materials and Engineering, EarlyView.
This review presents the potential of using natural plant fibers and biodegradable polymers as sustainable printed circuit boards (PCBs). This review provides future directions in innovation and sustainable PCBs development. Bio‐composites PCBs are both environmentally friendly and sustainable due to the natural fibres they contain.

Environmental Risk Assessment and Anti‐Corrosion Efficacy of Safe‐by‐Design Nitrite‐Based Nanomaterials for Maritime Applications

Nano Select, EarlyView.
The environmental behavior and impact of anti‐corrosion nanoadditives, ZnAl‐NO2 and MgAl‐NO2 layered double hydroxides (LDH), are assessed under marine conditions. These nanomaterials show instability in water but exhibit no or low toxicity to most tested marine species.
