Published: Sept. 16, 2024

Abstract A spur on miniaturized devices led scientists to unravel the fundamental aspects of micro‐ and nanoparticle assembly engineer large structures. Primarily, attention is given wet methods, whereas approaches in which solvents are avoided scarce. The “dry assembly” strategies can overcome intrinsic disadvantages that associated with assembly, e.g., lack versatility scalability. This review uniquely summarizes recent progress made create highly ordered particle arrays without using a environment. Before delving into these surface interactions (e.g., van der Waals, contact mechanics, capillary, electrostatics) elaborated, as profound understanding balancing critical aspect dry assembly. To manipulate interactions, involving different forces, mechanical‐based, electrical‐based, or laser‐induced, sometimes conjunction pre‐templated substrates, employed attain colloidal utilization structures obtained accompanied by specific examples. Dry methods aid us achieving more sustainable processes. Overall, this Review aims provide an easily accessible resource inspire researchers, including novices, broaden horizons significantly close remaining knowledge gap physical phenomena involved area.

Rational MOF Membrane Design for Gas Detection in Complex Environments

Small, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 23, 2024

Abstract Metal‐organic frameworks (MOFs) hold significant promise in the realm of gas sensing. However, current understanding their sensing mechanisms remains limited. Furthermore, large‐scale fabrication MOFs is hampered by inadequate mechanical properties. These two challenges contribute to sluggish development MOF‐based gas‐sensing materials. In this review, selection metal ions and organic ligands for designing first presented, deepening interactions between different ions/organic target gases. Subsequently, typical interfacial synthesis strategies (gas‐solid, gas‐liquid, solid‐liquid interfaces) are provided, highlighting potential constructing MOF membranes on superhydrophobic and/or superhydrophilic substrates. Then, a multi‐scale structure design proposed, including multi‐dimensional membrane heterogeneous design, improve performance through enhanced mass transfer specific sieving. This strategy anticipated augment task‐specific capabilities materials complex environments. Finally, several key future research directions outlined with aim not only further investigate underlying principles but also achieve efficient detection gases amidst interfering elevated moisture levels.

Abstract A key challenge in vaccine development is to induce an effective and durable immune response. Live virus vaccines lifelong antibody responses; however, the responses induced by inactivated or subunit decrease gradually. Activation of germinal center (GC) reaction, which generates long‐lived plasma cells (LLPCs), a mediator long‐term responses. To enhance activation GC, lymph node‐targeted delivery promoted enhancing deformability vector. In this study, double emulsion designed with strong containing chitosan nanoparticles (CSNP) internal aqueous phase (W NP ) for efficient antigen loading, called W /O/W. The flexible oil layer internally loaded positively charged particles endow deformability, continuously enrich model ovalbumin (OVA) nodes, activate B (GC B) T follicular helper (T FH cells, LLPCs, obtain high‐level persistence more than 5 months, significantly better traditional adjuvant. Concurrently, it also improves immune‐protective effect aged mice. Altogether, these results indicate that /O/W achieves node targeted strengthening generating high‐intensity responses, long‐lasting protection.
