Scalable and Integrated Photocatalytic Reactor Systems for Solar‐to‐Fuel Production: Photoredox and Photoreforming Processes

Advanced Energy Materials, EarlyView.
Solar fuels and other value‐added chemicals derived from light‐driven reactions are highly desirable. Although advanced photoactive materials have been reported, demonstrations of their feasibility in large‐scale production are needed. Hence, strategies and recent efforts in scaling up photocatalytic reactors and integrating them into comprehensive ...

Coronal Complexation Induces Snowman‐Shaped Janus Polymersome Formation

Angewandte Chemie, EarlyView.
Snowman‐like Janus polymersomes were produced in a simple, yet versatile two‐step approach involving a plasticizing agent and a cationic polymer additive to complex with the charged polymersome. Shape transformation was driven by coronal complexation altering membrane structure, followed by segregation of the polymer additive to form a protruding bleb ...

Elucidating the Impact of Functional Additives on the Structure and Ion Dynamics of Hybrid Solid Electrolytes

Advanced Energy Materials, EarlyView.
Using multinuclear and multiscale solid‐state NMR, the bulk and interfacial structures of a LiI‐integrated PEO‐LiTFSI‐Li6PS5Cl hybrid solid electrolytes are elucidated, revealing LiI's dual role in enhancing bulk Li‐ion mobility and facilitating Li‐ion diffusion across the organic/inorganic interfaces.

Geometry based heuristics for unit disk graphs

, 1994
Unit disk graphs are intersection graphs of circles of unit radius in the plane. We present simple and provably good heuristics for a number of classical NP-hard optimization problems on unit disk graphs. The problems considered include maximum independent set, minimum vertex cover, minimum coloring and minimum dominating set.

A Novel Quantification Method for High Voltage Structural Evolution in Sodium and Lithium Layered Oxides

Advanced Energy Materials, EarlyView.
High‐voltage cycling of layered alkali transition metal oxides in Li‐ and Na‐ion cells increases energy density but diminishes lifetime. A novel XRD‐analysis method, centered on the stacking factor “z”, is developed to quantify the stacking fractions in the OP hybrid structure.
