Regulating Phase Evolution and Crystallization Dynamics Enables Low Open‐Circuit Voltage Deficit in Wide‐Bandgap Cu2ZnSnS4 Solar Cells

Advanced Materials, EarlyView.
Bilayer composition‐modulated sulfurization (BCMS) regulates Cu redistribution in solution‐processed Cu2ZnSnS4, suppressing Cu2SnS3 and favoring the direct transformation pathway, while transforming the crystallization from surface‐dominated growth to a more synchronized process.

Commuting Signatures and Verifiable Encryption and an Application to Non-Interactively Delegatable Credentials [PDF]

, 2010
Verifiable encryption allows to encrypt a signature and prove that the plaintext is valid. We introduce a new primitive called commuting signature that extends verifiable encryption in multiple ways: a signer can encrypt both signature and message and ...

A Thermoreversible Gelation Pathway to Plant Cuticle‐Inspired Biopolymer Aerogel Monoliths Based on Network‐Spherulitic Crystal Assemblies

Advanced Materials, EarlyView.
To address functionality limitations in plant‐based and industrially compostable polymer aerogels, this work introduces bio‐inspired aerogels with broadened functionality. Inspired by functional plant tissues, lightweight biopolymer aerogels based on exclusively stereocomplex crystals are fabricated, featuring hierarchically macro‐/meso‐porous ...
