A Global Optimizer for Nanoclusters

Frontiers in Chemistry, 2019
We have developed an algorithm to automatically build the global minimum and other low-energy minima of nanoclusters. This method is implemented in PyAR (https://github.com/anooplab/pyar) program.

Opportunities and Challenges for Nanoparticle Synthesis using Continuous Flow Systems: A Magnetite Nanocluster Case Study [PDF]

, 2019
In this study, we demonstrate a new high temperature flow synthesis system for magnetite nanoparticle clusters. We find that successful synthesis of nanoparticle clusters is dependent on residence time in the reaction chamber and linear flow speed. The

Carrier‐Free Berberine/Nitidine Chloride Self‐Assembled Nanoparticles Induce Ferroptosis to Overcome Bortezomib Resistance in Multiple Myeloma

Advanced Science, EarlyView.
A schematic illustrating the fabrication process and ferroptosis‐mediated therapeutic mechanism of carrier‐free self‐assembled BBR/NC‐SAPs for overcoming bortezomib resistance in multiple myeloma. ABSTRACT Therapeutic relapse driven by bortezomib resistance represents a formidable clinical barrier in the management of multiple myeloma (MM).

Exploration of the Electronic and Catalytic Properties of [Co₅MS₈(PEt₃)₅]¹⁺ Nanoclusters: A Computational Study

Nanomaterials
Recent studies have demonstrated the relative stability of undercoordinated hexanuclear cobalt sulfide nanoclusters (NCs) with different charge states. Considering that these small metal NCs have atomically precise structures and high reactivity due to ...

α‐Synuclein Forms Distinct Micelle‐Like Assemblies at Low Ionic Strengths

Advanced Science, EarlyView.
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 ...

Imperfect Oriented Attachment of Gold Nanoparticles

Advanced Science, EarlyView.
The cover illustrates the imperfect oriented attachment of gold nanoparticles in liquid, as revealed by in situ liquid‐phase transmission electron microscopy. Triggered by the abrupt collapse of the interfacial hydration layer, two misoriented nanoparticles undergo a kinetically driven “jump‐to‐coalescence”.

Bright dual‐color electrochemiluminescence of a structurally determined Pt1Ag18 nanocluster

Aggregate
Metal nanoclusters possess excellent electrochemical, optical, and catalytic properties, but correlating these properties remains challenging, which is the foundation to generate electrochemiluminescence (ECL). Herein, we report for the first time that a

Controlling pH-Dependent Nanozyme Activity by Metal Identity in Histidine-Based Nanoarchitectures

Nanomaterials
In this paper, we report a metal-driven structural tuning strategy with the L-histidine (His) ligand to modulate peroxidase-like nanozyme performance. Although the His coordinates with gold(III) ions to form an extended helical coordination polymer, its ...
