Characterization and Reuse of Lithium‐ion Battery Cathode Material Recovered Through a Bacterial Process

open access: yesAdvanced Energy Materials, EarlyView.
A sustainable bacteria‐based lithium‐ion battery cathode recycling method is optimized using engineering biology. The resulting biomineralized manganese carbonate species is found to be easily converted into an electrode material, via simple calcination.

The sustainome of global goal interactions varies by country income and is disproportionately influenced by inequalities [PDF]

open access: yesNature Sustainability 2(3): 242-247 (2019), 2018
We interact with each other and our environment in rich and complex ways. These interactions form socioecological systems in which human, economic, or natural resources are used and replenished. In 2015, the United Nations set seventeen sustainable development goals (SDGs) to attempt to change the way we live and create by 2030 a sustainable future ...

Closed N=2 Strings: Picture-Changing, Hidden Symmetries and SDG Hierarchy

open access: yes, 1999
We study the action of picture-changing and spectral flow operators on a ground ring of ghost number zero operators in the chiral BRST cohomology of the closed N=2 string and describe an infinite set of symmetry charges acting on physical states.

Synthesis of Pt Carbon Aerogel Electrocatalysts with Multiscale Porosity Derived from Cellulose and Chitosan Biopolymer Aerogels via Supercritical Deposition for Hydrogen Evolution Reaction

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The synthesis of platinumcarbon aerogel electrocatalysts with multiscale porosity derived from biopolymer aerogels via supercritical deposition is presented. The electrocatalysts demonstrate similar overpotentials to commercial alternatives with significantly higher platinum loadings, while exhibiting superior stability due to enhanced porosity ...
