Ternary Inclusion Co‐Crystals for Efficient Photothermal Conversion and Solar‐Driven Water Evaporation

open access: yesAdvanced Science, EarlyView.
An inclusion co‐crystal strategy for elevating photothermal conversion efficiency is developed. A Tröger's base molecular box strongly bind two electron‐deficient TCNQ forming 1:2 ternary inclusion charge‐transfer co‐crystals, which displays a high photothermal efficiency of 94.3%.

The Topology of the Unitary Dual of Crystallography Groups [PDF]

open access: yesarXiv
We provide a procedure for generating the irreducible representations of crystallography groups in any dimension. We also furnish a strategy to investigate the topology of the unitary dual of a crystallography group using sequences of matrices. All irreducible representations (up to unitary equivalence) of the dimension 3 crystallography group 90 and ...

Cosmic crystallography in a circle [PDF]

open access: yesarXiv, 2000
In a circle (an S^1) with circumference 1 assume m objects distributed pseudo-randomly. In the universal covering R^1 assume the objects replicated accordingly, and take an interval L>1. In this interval, make the normalized histogram of the pair separations which are not an integer. The theoretical (expected) such histogram is obtained in this report,

Direct Visualization and Quantitative Insights into the Formation and Phase Evolution of Cu Nanoparticles via In Situ Liquid Phase 4D‐STEM

open access: yesAdvanced Science, EarlyView.
By integrating in situ liquid phase transmission electron microscopy (LP‐TEM) with 4D scanning transmission electron microscopy (4D‐STEM), this work not only reveals the morphology and phase evolution of Cu nanoparticles during electrodeposition and electrooxidation processes but also demonstrates the possibility of mapping the grain size and phase ...

Combinatorial problems of (quasi-)crystallography [PDF]

open access: yesIn: Quasicrystals - Structure and Physical Properties, ed. H.-R. Trebin (Wiley-VCH, Weinheim, 2003), pp. 160-171, 2002
Several combinatorial problems of (quasi-)crystallography are reviewed with special emphasis on a unified approach, valid for both crystals and quasicrystals. In particular, we consider planar sublattices, similarity sublattices, coincidence sublattices, their module counterparts, and central and averaged shelling.

Palladium‐Catalyzed Dual Csp2─Csp3 Bond Formation: A Versatile Platform for the Synthesis of Benzo‐Fused Heterocycles

open access: yesAdvanced Science, EarlyView.
Pd(II)/Cu(I) co‐catalyzed dual Csp2─Csp3 bonds construction from unactivated alkenes and arylsulfonyl chlorides to access benzo‐fused heterocycles with high efficiency and chemoselectivity. Abstract Transition‐metal‐catalyzed transformations offer a powerful approach to rapidly synthesize complex benzo‐fused heterocycles, crucial for drug and material ...

Pushing the Frontiers: Artificial Intelligence (AI)‐Guided Programmable Concepts in Binary Self‐Assembly of Colloidal Nanoparticles

open access: yesAdvanced Science, EarlyView.
Colloidal nanoparticles self‐assembly advances towards intelligent, customized assembly through precise control of binary co‐assemblies. This review explores the evolution from monolithic to binary assemblies, highlighting how the AI‐guided programmable assembly approach has the potential to shift from passive assembly to active intelligent design.
