Plastic Deformation of LiNi0.5Mn1.5O4 Single Crystals Caused by Domain Orientation Dynamics

Advanced Energy Materials, EarlyView.
The nanoscale mechanisms of Li‐ion deintercalation in battery cathodes, particularly the role of crystallographic defects, remain unclear. Using scanning X‐ray diffraction microscopy and multi‐crystal diffraction, microstrain and lattice misorientations are examined in LMNO cathodes particles during and after cycling.

Concurrent Operando Neutron Imaging and Diffraction Analysis Revealing Spatial Lithiation Phase Evolution in an Ultra‐Thick Graphite Electrode

Advanced Energy Materials, EarlyView.
The lithiation phases in an ultra‐thick graphite electrode are mapped operando as a function of electrode depth through a new method concurrently combining neutron imaging and diffraction. The results reveal the coexistence of lithiation phases during cycling as well as the solid electrolyte interface (SEI) formation and capacity loss through non ...

Heterogeneity of the Dominant Causes of Performance Loss in End‐of‐Life Cathodes and Their Consequences for Direct Recycling

Advanced Energy Materials, EarlyView.
Direct recyling of Li‐ion battery materials promises a low‐cost path towards a secure domestic supply of critical materials for batteries. Using cathode material from an end‐of‐life commercial Li‐ion cell, this work identifies the primary degradation mechanisms that diminish the performance of directly reused cathode materials and includes a discussion

Synthesis of (−)‐8a‐epi‐Lentiginosine via Tsuji–Trost Reaction of d‐Glucose‐Derived Allylic Alcohols and Crystal Structure Analysis

Asian Journal of Organic Chemistry, EarlyView.
A facile synthetic route to (−)‐8a‐epi‐lentiginosine from d‐glucose using the Pd‐BiPhePhos catalyzed intramolecular Tsuji–Trost reaction of non−derivatized allylic alcohol as a key construction of the hydroxylated pyrrolidine ring is reported. The crystal structure of (−)‐8a‐epi‐lentiginosne showed the envelope conformation of the five‐membered ring ...

C3‐Symmetric Chiral Cage‐Shaped Phosphates: Synthesis and Application as Organocatalysts in Asymmetric Iodolactonizations

Asian Journal of Organic Chemistry, EarlyView.
Two C3‐symmetric cage‐shaped phosphates were successfully synthesized and their activity as chiral Lewis‐basic catalysts for enantioselective iodocyclizations was evaluated. The different tethered groups of these phosphates influences their catalytic performance, leading to substrate‐dependent variations in reactivity and selectivity, showcasing the ...

Synthesis of Benzodithieno[5.5.5.6]fenestranes: Unexpected Epimerization and Regiochemical Outcomes

Asian Journal of Organic Chemistry, Accepted Article.
Isomeric [5.5.5.6]fenestranes bearing one benzene and two thiophene rings annulated to all‐cis‐ and cis,cis,trans,cis‐fenestrane cores are presented. The synthesis route previously established for the corresponding tribenzo[5.5.5.6]fenestranes includes twofold cyclodehydration of the stereoisomeric spiro[cyclohexane‐1,2’‐indane]‐1',3'‐diol ...
