Prismatic cohomology and de Rham-Witt forms [PDF]

arXiv, 2020
For any prism $(A, d)$ we construct a canonical map $W_r(A/d)\to A/d\phi(d)\ldots\phi^{r-1}(d)$. This map is necessary for existence of a canonical base change comparison between prismatic cohomology and de Rham-Witt forms. We construct a canonical map from prismatic cohomology to de Rham-Witt forms and prove that it is an isomorphism in the perfect ...

Decoding the Structure of Benzodithiophene Polymers for High‐Efficiency Organic Solar Cells

Advanced Functional Materials, EarlyView.
This study reveals a unique solid mesophase in top‐performing benzodithiophene‐based polymers for solar cells, comprising stacked solid‐like and liquid‐like layers. Combining nanoscale fibrillar domains with amorphous regions, it introduces a new structural paradigm.

Vat Photopolymerization of High Molecular Weight Polymer Latexes with Pseudothermoplastic Properties for Recyclability

Advanced Functional Materials, EarlyView.
A photocurable latex system enables high‐resolution vat photopolymerization of water‐dispersed thermoplastics, yielding pseudothermoplastic materials with recyclability. The formulation permits precise control over mechanical properties and supports reprocessing through conventional and extrusion‐based methods. Compatibility with two‐photon 3D printing
