With the average global temperature steadily increasing, there is growing interest in new technologies for carbon capture, utilization, and storage. This coincides with the decrease in cost of intermittent renewable electricity sources, specifically solar energy, necessitating new methods for energy storage. The authors analyze the effectiveness of model photovoltaic-driven carbon dioxide conversion technologies that produce liquid alcohols as compared to planting an equivalent forest. doi.org/10.1557/mre.2020.32

The authors discuss effective water-resistant bioelectrodes for long-term biological monitoring, emphasizing the importance of conducting polymer materials such as poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate). This will help make it possible to assess the performances of athletes in water-based sports. doi.org/10.1557/mrc.2020.72

Renewable hydrogen for the chemical industry Nigel Rambhujun, Muhammad Saad Salman, Ting Wang, Chulaluck Pratthana, Prabal Sapkota, Mehdi Costalin, Qiwen Lai, Kondo-Francois Aguey-Zinsou

Rugged nanoparticle tracers for mass tracking in explosive events Lance Hubbard, Ryan Sumner, Martin Liezers, Trevor Cell, Clara Reed, Nicolas Uhnak, Caleb Allen, Brittney Berry, Hugh Currah, Erin Fuller, Erin Kinney, Nathaniel Smith, Michael Foxe, April Carman

The chemical industry will become the major driver for oil production by 2030, relying entirely on sufficient oil supply. However, using renewable hydrogen as a fuel could help decarbonize all of chemical manufacturing. The authors summarize existing technologies for the production of renewable hydrogen including biomass and water electrolysis, and methods for the effective storage of hydrogen with an emphasis on the need for mitigation strategies to enable such a transition. doi.org/10.1557/mre.2020.33

Investigation of high-energy materials is conducted by tracing the flow of solid matter during an explosion. This can be done with silica-covered semiconductor quantum dots. Such an effective quantification will lead to better mechanistic determination in future energetic materials and systems. doi.org/10.1557/mrc.2020.70

How to avoid the perfect storm: The role of energy and photovoltaics

L. Arnaud, C. Karam, N. Bresson, C. Dubarry, S. Borel, M. Assous, G. Mauguen, F. Fournel, M. Gottardi, T. Mourier, S. Cheramy, F. Servant

Energy, water, and food shortages, along with irreversible environmental damage and climate changes, will happen within a decade if the current course of action is maintained, preparing the “perfect storm” – interrelated events that could lead to major stress on global systems.
