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.

Mitochondrial–Nuclear Epistasis Impacts Fitness and Mitochondrial Physiology of Interpopulation Caenorhabditis briggsae Hybrids

open access: yesG3: Genes, Genomes, Genetics, 2016
In order to identify the earliest genetic changes that precipitate species formation, it is useful to study genetic incompatibilities that cause only mild dysfunction when incompatible alleles are combined in an interpopulation hybrid. Such hybridization

Speciation with gene flow via cycles of isolation and migration: insights from multiple mangrove taxa

open access: yesbioRxiv, 2018
Allopatric speciation requiring an unbroken period of geographical isolation has been the standard model of neo-Darwinism. While doubts have been repeatedly raised, strict allopatry without any gene flow remains a plausible mechanism in most cases.

Understanding Structural and Compositional Evolution during NMC Cathode Direct Recycling via Solid‐State NMR

open access: yesAdvanced Energy Materials, EarlyView.
Direct recycling end‐of‐life lithium‐ion batteries (LIB) to recover high‐value cathode materials such as LiNixMnyCozO2 (NMC) requires method development and detailed characterization. In this work, the unique capabilities of solid‐state NMR in characterizing changes in local ordering within NMC cathode materials during recycling and upcycling as well ...

Contemporary Trends in Lithium‐Sulfur Battery Design: A Comparative Review of Liquid, Quasi‐Solid, and All‐Solid‐State Architectures and Mechanisms

open access: yesAdvanced Energy Materials, EarlyView.
Contemporary advances in lithium–sulfur batteries are mapped across liquid, quasi‐solid, and all‐solid‐state architectures. The review clarifies operating mechanisms, highlights transition from polysulfide‐mediated to solid‐state conversions, and surveys state‐of‐the‐art materials and characterization. Commercial hurdles and actionable design rules are

In Situ NMR and Kinetics Reveal Origins of Regioselectivity Differences for Epichlorohydrin Ring‐Opening in Lewis and Brønsted Acid Zeolites

open access: yesAngewandte Chemie, EarlyView.
Regioselectivities for epichlorohydrin ring‐opening over Brønsted and Lewis acid zeolites change by an order of magnitude upon replacing fractions of methanol with acetonitrile co‐solvent. Combining transient operando 13C‐NMR with traditional kinetic measurements reveals that these differences originate from competition between an SN1 pathway through ...

Optimizing Lithium Nucleation Overpotential in Anode‐Free Garnet‐Based Hybrid Solid‐State Batteries

open access: yesAdvanced Energy Materials, EarlyView.
A hybrid solid–liquid electrolyte approach using additives based on localized high‐concentration electrolyte with a trilayer garnet enables a stable, ionically conductive interphase for anode‐free solid‐state lithium batteries. Cu/Li half‐cells show 81% Coulombic efficiency over 300 cycles, while pouch cells retain 75% capacity after 400 cycles at 1C ...

Self‐Stabilized Heterometallic Pair Sites for Selective Ethanol Dehydrogenation on Pt–Cr–Ag Alloy Catalysts

open access: yesAngewandte Chemie, EarlyView.
Trimetallic PtxCrxAg1‐x (x < 0.1) alloys feature active Pt–Cr pairs for non‐oxidative ethanol dehydrogenation. Operando X‐ray spectroscopy confirms the preferential formation of Pt–Cr pairs dispersed throughout an Ag matrix and demonstrates that the Pt–Cr sites have high activity and selectivity for catalytic ethanol dehydrogenation, while suppressing ...
