Liquid Phase Transmission Electron Microscopy: A Window into the Early Stages of Complex Material Formation

Advanced Functional Materials, EarlyView.
Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

Powering Nanocrystal‐Based Heat Engines With Light‐Emitting Metasurfaces That Influence Their Temperature

Advanced Functional Materials, EarlyView.
Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...

Zero-Knowledge Proofs of Quantumness

IACR Communications in Cryptology
With the rapid development of quantum computers, proofs of quantumness have recently become an interesting and intriguing research direction. However, in all current schemes for proofs of quantumness, quantum provers almost invariably face the risk of being maliciously exploited by classical verifiers.

Bibliometric survey on Zero-Knowledge Proof for Authentication

, 2021
Background: Zero Knowledge Proof is a persuasive cryptographic protocol employed to provide data security by keeping the user\u27s identity, using the services anonymously. Zero Knowledge Proof can be the preferred option to use in multiple circumstances.

Pickering‐Engineered Microparticles for Magnetically Guided Motion and Light‐Triggered Catalysis

Advanced Functional Materials, EarlyView.
Magnetically responsive wax microparticles stabilized by hematite cubes through the Pickering emulsification strategy are developed, showing controlled size, motion, and light‐activated catalytic activity. Annealing under a magnetic field enhances their mobility and steering.

Efficient Zero-Knowledge Proofs [PDF]

, 2011
A zero-knowledge proof is a two-party protocol that enables a prover to convince a verifier of the truth of a statement without revealing anything else. Zero-knowledge proofs are widely used in cryptography to guarantee that parties are acting correctly without revealing their private information.
