Protected Chaos in a Topological Lattice

open access: yesAdvanced Science, EarlyView.
Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.

From Ancient Techniques to Modern Solutions: In Situ Synthesis of C‐S‐H for Sandstone Conservation

open access: yesAdvanced Science, EarlyView.
Herein, this work presents a paleo‐inspired approach to synthesizing and optimizing C‐S‐H‐based grouting mortars for conserving the sandstone of Beishan Grottoes, Dazu Rock Carvings, China. By achieving an optimal recipe compatible with natural sandstone, this work demonstrates the pivotal role of hydrogen bonding in the adhesion between C‐S‐H mortars ...

Assembling Hexahedral Supramolecular Nano‐Aggregates on Rice Wax Layer Matrices to Promote the Leaf Deposition and Bioavailability of Bactericides for Plant Protections

open access: yesAdvanced Science, EarlyView.
To address the problem of off‐target movement and low bioavailability of pesticides, two anisotropic supramolecular building units (BiTA18@β‐CD and BiTA18@γ‐CD) have been invented that can self‐assemble into nano‐sized hexagonal cuboids on the rice microcrystalline matrix. This manipulation realizes the enhanced utilization of bactericides for rice and

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

open access: yesAdvanced 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 ...

Spatially Regulated Gas Flow Control for Batch‐Drying of Large Area Slot‐Die‐Coated Perovskite Thin Films

open access: yesAdvanced Energy Materials, EarlyView.
Innovations are crucial for transferring high power conversion efficiencies (PCEs) to large‐scale perovskite devices. Here, a 2D regulated gas flow control for batch‐drying of slot‐die‐coated perovskite films is introduced. This drying method achieves homogeneous, pinhole‐free large‐area perovskite/silicon tandem solar cells and perovskite solar ...

Food waste, date labels, and risk preferences: An experimental exploration

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract This study provides theoretical and experimental evidence that consumers adjust their premeditated food waste by date labels and their risk and loss preferences. The “Use by” date label leads to more premeditated food waste than “Best by” for deli meat and spaghetti sauce.

The effects of extreme weather on rural transportation infrastructure and crop prices along the Lower Mississippi River

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract Extreme weather events are worsening the fragile rural infrastructure in the United States, impacting trade flows of agricultural products. The Mississippi River, vital for transporting agricultural commodities, reached historic lows during the 2022 and 2023 fall harvests, increasing transportation costs and lowering crop prices.

Conceptualising quality early childhood education: Learning from young children in Brazil and South Africa through creative and play‐based methods

open access: yesBritish Educational Research Journal, EarlyView., 2023
Abstract Early childhood has increasingly been acknowledged as a vital time for all children. Inclusive and quality education is part of the United Nations Sustainable Development Goals, with the further specification that all children have access to quality pre‐primary education.
