Engineering Na‐Rich P2‐Type Layered Oxides Through Li/Ti Dual Doping for Oxygen Redox Activation and Superior Structural Stability

Advanced Energy Materials, EarlyView.
P2‐type sodium layered oxides have potential for high‐voltage operation but suffer from structural instability and capacity fading. This work demonstrates that synergistic Li and Ti co‐doping enhances sodium inventory, suppresses detrimental phase transitions, and activates reversible lattice oxygen redox.

Grid patterning protocol for Cryo-FIB/ET workflow v1

, 2023
Cryo-Electron Tomography combined with Cryo-Focused Ion Beam milling provides a novel way to study the structure of proteins and the architecture of organelles in situ. Electron microscopy grid preparation is a key step toward a successful Cryo-FIB/ET workflow execution. Here we provide an optimized protocol to generate photo-micropatterns on the grids

A Quantitative Lithium Inventory Framework for Anode‐Free Lithium Metal Batteries

Advanced Energy Materials, EarlyView.
A component‐resolved lithium inventory framework quantitatively tracks Li redistribution across the cell in anode‐free NMC622||Cu pouch cells throughout cycling. Three sequential degradation stages are identified: formation‐driven cathode Li depletion, midlife inactive Li0 accumulation, and late‐stage runaway SEI thickening. The cathode, as the sole Li

New approach for FIB-preparation of atom probe specimens for aluminum alloys.

PLoS ONE, 2020
Site-specific atom probe tomography (APT) from aluminum alloys has been limited by sample preparation issues. Indeed, Ga, which is conventionally used in focused-ion beam (FIB) preparations, has a high affinity for Al grain boundaries and causes their ...

Characterizing Biopolymer Electrolytes in Zinc–Air Batteries: Challenges, Best Practices, and a Robust Workflow Guiding Future Research Paths

Advanced Energy Materials, EarlyView.
Bio‐based gel polymer electrolytes promise sustainable, mechanically adaptable zinc–air batteries, yet their progress is constrained by inconsistent characterization. This review critically links formulation, structure, interfaces, and cell performance, identifies methodological gaps under alkaline operating conditions, and proposes application ...

Workflow for Fluorescence-Targeted Lamella Milling From Vitrified Cells With a Coincident Fluorescence, Electron, and Ion Beam Microscope

Bio-Protocol
Cryo-electron tomography (cryo-ET) is the main technique to image the structure of biological macromolecules inside their cellular environment. The samples for cryo-ET must be thinner than 200 nm, which is not compatible with micron-sized cells.
