Graphene‐Engineered Rear Interfaces Enable Efficient Flexible CZTSSe Solar Cells on Metal Foils

open access: yesAdvanced Science, EarlyView.
An atomically thin graphene interlayer stabilizes the rear interface of flexible CZTSSe solar cells by regulating interfacial stress, suppressing detrimental interfacial reactions, and reducing the back‐contact barrier. This strategy simultaneously improves photovoltaic performance and mechanical durability.

Enhanced Hydrogen Evolution Activity of MoS2 Through Solid Solution Modification of Its Edge Sites With Ruthenium

open access: yesAngewandte Chemie, EarlyView.
Modulating the edge sites of molybdenum disulfide significantly boosts hydrogen production. By depositing Ru to form an edge‐coordinated solid solution, we accelerate water dissociation and shift the hydrogen evolution reaction pathway to Volmer–Tafel.

Natural‐Inspired Engineered Microalgae With Selenium Enrichment Enabled Potent Anti‐Tumor Immunity

open access: yesAdvanced Science, EarlyView.
Se‐Ssp was engineered as a potent immunomodulator for activating innate immunity via the TLR and cGAS‐STING pathways, therefore converting “cold” tumors into “hot” tumors to achieve high efficacy and long‐term therapeutic outcomes. ABSTRACT Immunotherapy has shed light on clinical oncology for several decades.

A heterogeneous crowd evacuation model integrating multi-dimensional panic emotion characteristics

open access: yesJournal of Physics: Complexity
In emergency evacuation scenes, environmental uncertainties and information deficits often trigger panic among individuals, which in turn impairs their ability to make sound judgments and decisions.

Biomimicry of crowd evacuation with a slime mould cellular automaton model

open access: yes, 2015
© Springer International Publishing Switzerland 2015. Evacuation is an imminent movement of people away from sources of danger. Evacuation in highly structured environments, e.g. building, requires advance planning and large-scale control.

Anode‐Free Sodium Metal Batteries: From Materials Design to System‐Level Integration

open access: yesAdvanced Science, EarlyView.
Anode‐free sodium metal batteries hold no sodium reserve, so every inefficiency becomes permanent loss. Resolving the inventory into reversible, dead, and chemically bound fractions exposes what Coulombic efficiency hides. Practical 500‐cycle operation requires above 99.95%, a threshold few systems meet under lean electrolyte and high areal capacity ...

Nonlinear Ion‐Specific Control of Underwater Adhesion by Bottlebrush Polymer Interfaces

open access: yesAdvanced Science, EarlyView.
The efficiency of underwater adhesion is modulated by ion‐specific effects. Strongly hydrated Na+ remains separated from the mica surface by its hydration shell, preserving access to binding sites, whereas weakly hydrated K+ can partially dehydrate and occupy ditrigonal cavities.

Diversified Crowd Evacuation Method in Large Public Places

open access: yesIEEE Access, 2019
Realistic crowd simulation is an important issue for crowd management, public space design, and architectural and urban planning. In this paper, we present a novel approach for planning and directing heterogeneous large-scale crowd in public places.

Enhancing Specific Stiffness of Nano‐Architected Materials Through Generative AI and Active Learning

open access: yesAdvanced Science, EarlyView.
A structure‐centric generative framework searches voxelated design space directly, coupling a variational autoencoder with multi‐objective optimization and active learning to progressively expand the validated design domain. The discovered nano‐architectures, realized as pyrolytic carbon by two‐photon lithography, deliver 18–23% higher stiffness and 26–
