Silver Nanoclusters Encapsulated into Metal–Organic Frameworks for Rapid Removal of Heavy Metal Ions from Water

Molecules, 2019
Metal nanomaterials have been reported as effective absorbents for the removal of pollutants in the water system, but the release of ions from these nanomaterials brings another concern.

Electrooxidation, Size Stability, and Electrocatalytic Activity of 0.9 nm Diameter Gold Nanoclusters Coated with a Weak Stabilizer

ChemElectroChem, 2020
We describe the electrooxidation and size stability of 0.9 nm average diameter triphenylphosphine monosulfonate (TPPS)‐stabilized Au nanoclusters (NCs) as compared to 1.6 nm tetrakis(hydroxymethyl)phosphonium chloride (THPC)‐stabilized Au NCs and 4.1 nm ...

Nanocluster‐Assisted OH Ligand Modification Optimizes Activity and Stability of Fe‐N‐C Catalysts [PDF]

Advanced science
A nanocluster‐assisted ligand engineering stabilizes OH‐modified FeN4 active sites through strong electronic coupling between isolated Fe atoms and adjacent nanoclusters. This synergy optimizes oxygen‐intermediate adsorption, lowers ORR energy barriers, and breaks the conventional activity–stability trade‐off, enabling high ORR activity, exceptional ...

On the evolution of nanocluster size distribution in a nanocluster aggregation source [PDF]

Journal of Applied Physics, 2012
This paper presents a detailed model of cluster formation from a supersaturated atomic vapor in an inert buffer gas. The population balance equations for the cluster size distribution are based on the Smoluchowski coagulation equation and take into account (i) convective diffusion of clusters, (ii) cluster loss to walls of an aggregation chamber, and ...

Ras nanoclusters [PDF]

Small GTPases, 2013
Ras proteins on the plasma membrane are laterally segregated into transient nanoclusters that are essential for high-fidelity signal transmission by the Ras/MAPK cascade. The dynamics of Ras nanocluster assembly and disassembly control MAPK signal output. BRaf inhibitors paradoxically activate CRaf and MAPK signaling in Ras-transformed cells.

Activating the potent antimicrobial activities of gold nanoclusters against multidrug resistant Pseudomonas aeruginosa [PDF]

, 2022
In this work we show that biological inactive gold nanoclusters (AuNCs) capped with D-maltose can be converted to antimicrobial AuI species by the addition of thiourea (TU).

α-Synuclein Forms Distinct Micelle-Like Assemblies at Low Ionic Strengths. [PDF]

Adv Sci (Weinh)
At high ionic strength, α‐synuclein forms diverse assemblies, including oligomers, fibrils, and condensates. Here, we show that at low ionic strength, α‐synuclein adopts a distinct, low‐abundance assembly state. These assemblies maintain a constant size above a critical concentration and do not coalesce, suggesting a micelle‐like organization ...

Near-Unity Photothermal Conversion in Bimetallic M₄₄ and M₈₁ Nanoclusters Enables NIR-Driven Photo-Thermo-Electricity Generation. [PDF]

Adv Sci (Weinh)
Atomically precise nanoclusters of Au/Ag alloys are explored as high‐performance photothermal materials, delivering record‐high photothermal efficiencies (up to 91%). Photo‐thermo‐electricity is further demonstrated by integrating nanocluster films with thermoelectric devices.
