Nanomaterial Integration at Liquid–Liquid Interfaces for Green Catalysis

open access: yesAdvanced Materials, EarlyView.
Functional nanomaterials assembled at liquid–liquid interfaces create dual‐role platforms serving as emulsion stabilizers and catalytic sites, offering enhanced reaction kinetics with improved catalyst recovery and recyclability. This review examines design strategies, structure‐performance relationships, and industrial implementation prospects of ...

Optimizing Evacuation Strategies in Mountain Communities to Mitigate Geohazards Risk: A Hybrid Simulation Framework

open access: yesInternational Journal of Disaster Risk Science
Evacuation strategies play a crucial role in mitigating human casualties from geohazards. While evacuation simulations have been widely used to investigate crowd behavior in response to disasters such as fires and earthquakes, their application to ...

A Multi-Species Artificial Bee Colony Algorithm and Its Application for Crowd Simulation

open access: yesIEEE Access, 2019
The artificial bee colony (ABC) algorithm has the problem of slow convergence and may be trapped into local optimum. In this paper, a multi-species ABC (MABC) algorithm is proposed based on the multi-swarm model.

Can cooperation slow down emergency evacuations? [PDF]

open access: yes, 2012
We study the motion of pedestrians through obscure corridors where the lack of visibility hides the precise position of the exits. Using a lattice model, we explore the effects of cooperation on the overall exit flux (evacuation rate). More precisely, we

Hybrid Magnetoactive Soft Elastomers: Material Development Toward Application in Diaphragm Pumps

open access: yesAdvanced Materials Technologies, EarlyView.
Hybrid magnetoactive soft elastomeric membranes are developed by combining two different types of magnetic particles. The membranes exhibit distinct mechanical, magnetic and thermal properties owing to the unique characteristics of the two magnetic particles.

Steric Hindrance and Secondary Interactions Govern Reconfiguration Between Two Complex CuI Coordination Cages

open access: yesAngewandte Chemie, EarlyView.
Fine‐tuning steric and C─H···π contacts directs assembly of two CuI cages. An identical naphthylene‐based subcomponent forms a [CuI12L6]12+ pseudo‐hexagonal prism stabilized by 29–32 C─H···π contacts and 12 arene stacking pairs with 6‐methyl‐2‐formylpyridine, whereas the 3‐methyl analog imparts steric clashes, yielding a [CuI8L4]8+ open prism ...

Pedestrians moving in dark: Balancing measures and playing games on lattices [PDF]

open access: yes, 2013
We present two conceptually new modeling approaches aimed at describing the motion of pedestrians in obscured corridors: * a Becker-D\"{o}ring-type dynamics * a probabilistic cellular automaton model.

Tailoring Vascular‐Immune Homeostasis via Manganese‐DNA Complex‐Armed Immunogenic Extracellular Vesicles for Pancreatic Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
This study demonstrates that Mn2⁺–tumor DNA complexes encapsulated in dendritic cell (DC)– derived immunogenic extracellular vesicles (EVDC@Mn‐DNA) act as a DC‐specific cGAS– STING activator. EVDC@Mn‐DNA treatment enhances intratumoral DC activation, improves tumor vascular function, promotes CD8⁺ T cell activity, and suppresses pancreatic tumor growth,

Hydrogen Isotope Exchange in Pyridine Catalyzed by an Iron(II) Imido Complex: Counterion‐Directed Regioselectivity

open access: yesAngewandte Chemie, EarlyView.
Anionic high‐spin iron(II) imido complexes are catalysts for the hydrogen isotope exchange (HIE) reaction with pyridine as the substrate. The alkali metal counter‐cation plays critical roles in activating the substrate and facilitating deuteration. These complexes catalyze site‐selective α‐, α,β,γ‐, and β,γ‐deuteration of pyridine, where the counter ...

Study of Split-Flow Wall Located at Exit

open access: yesAdvances in Civil Engineering, 2017
Congestion is the major cause of crowd stampede-trampling and crushing incidents. To alleviate the phenomenon of congestion in the process of evacuation, theory of split-flow wall is put forward to optimize the evacuation and the principle of it is ...
