Prospects on large-scale manufacturing of solid state batteries

Kelsey B. Hatzell, Yanjie Zheng

Solid state batteries that utilize energy dense anodes may have similar manufacturing costs as traditional lithium ion batteries. The authors highlight the state of the art for solid-state battery manufacturing approaches and the importance of utilization of conventional battery manufacturing approaches for achieving price parity in the near term.

Toward a least-effort principle for evaluating prices of elements as indicators of sustainability

Radha Perumal Ramasamy, Alan J. Hurd

Open Access

The authors use certain rank to understand the price of chemical elements. The key observation is that the role of the volume from global mining production dominates in materials economics. Borrowing from an analogy to Zipf’s Law leads to a power-law relationship between abundance and rank that may suggest the price paid for elemental materials optimizes efficient utilization.

Hydrogen technologies for energy storage: A perspective

Ned Stetson, Marika Wieliczko

Hydrogen is a versatile energy-storage medium with significant potential for integration into the modernized grid. Advanced materials for hydrogen storage technologies, including adsorbents, metal hydrides, and chemical carriers, play a key role in bringing hydrogen to its full potential. The authors provide an overview of the US Department of Energy Hydrogen and Fuel Cell Technologies Office R&D activities in hydrogen storage technologies within the Office of Energy Efficiency & Renewable Energy.


Microbial repellence properties of engineered spider silk coatings prevent biofilm formation of opportunistic bacterial strains

Christoph Sommer, Hendrik Bargel, Nadine Raβmann, Thomas Scheibel

Bioinspired coatings and implant devices enable better integration in biomedical devices – they mimic chemistry and also thermomechanical properties. In the case of spider silk surfaces, the authors highlight their efficacy in microbe-repellent properties and their potential use for surface modification including silicone-based implants. Interesting characterization and assay studies are in order.

Supramolecular tools for polymer additive manufacturing

Danielle R. Berry, Karen P. Cortés-Guzmán, Alejandra Durand-Silva, Sachini D. Perera, Ashele K. Remy, Qing Yan, Ronald A. Smaldone

New polymers are constantly being investigated for applications and utility in additive manufacturing. There is interest in optimizing thermomechanical properties but also in extending functionality and sustainability. The authors highlight supramolecular chemistry and dynamic covalent and noncovalent bonds as a path to extend investigation of new materials for 3D printing.

Possibility of interstitial Na as electron donor in Yb14MgSb11

Naomi A. Pieczulewski, Max Wood, Michael Y. Toriyama, James P. Male, Kent J. Griffith, G. Jeffrey Snyder

Solid-state properties of MgSb class of inorganic complexes have interesting properties for thermal conductivity, Seebeck coefficient improvement and resistivity. A potential route to increase carrier concentration as reported by the authors is based on an improved understanding of multiband models. Density functional theory calculations are useful for investigating defect-modified carrier concentrations at the equilibrium phase.
