Complex hollow structures of metal sulfides could be promising materials for energy storage devices such as supercapacitors and lithium‐ion batteries. However, it is still a great challenge to fabricate well‐defined with multi‐shells, hierarchical architectures, non‐spherical shape. In this work, template‐engaged strategy developed synthesize NiS box‐in‐box double‐shells. The constructed by ultrathin nanosheets are evaluated electrode supercapacitors. As expected, the exhibit excellent rate...
Regulating the Zn deposition orientation is an efficient way to suppress dendrites and stabilize anodes in aqueous ion batteries (ZIBs). Few studies have been conducted control Zn(002) by altering Zn2+ solvation structure with a cosolvent. Herein, bifunctional high-polarity cosolvent hexamethylphosphoramide (HMPA) proposed electrolyte. It not only suppresses H2 evolution reaction via reshaped decreased H2O activity but also induces hexagonal-close-packed morphology due strong absorption...
We show that partial inhibition of the emerging Ag domain can be achieved by controlling growth dynamics. With symmetry broken "fresh" surface, sequentially gives (Au sphere)-(Ag wire)-(Ag plate) triblock nanostructures. This new understanding opens doors to sophisticated synthetic designs, broadening horizon our search for functional architectures.
The shape anisotropy of nanoparticle building blocks is critical importance in determining their packing symmetry and assembly directionality. While there has been extensive research on the effect overall geometric shapes, nanometer morphology details not well-recognized or understood. Here we draw shape-anisotropic gold triangular nanoprism synthesized based a method recently developed; besides "large-scale" prism (79.8 nm side length 22.0 thickness), prisms are beveled with sides convexly...
With the increase in dependence on renewable energy sources, interest storage systems has increased, particularly with solar cells, redox flow batteries, and lithium batteries. Multiple diagnostic techniques have been utilized to characterize various factors relation battery performance. Electrochemical tests were used study density, capacity, cycle life, rate, other related properties. Furthermore, it is critical correlate information collected from characterization of materials its...
Abstract Numerous mechanisms have been studied for chemical reactions to provide quantitative predictions on how atoms spatially arrange into molecules. In nanoscale colloidal systems, however, less is known about the physical rules governing their spatial organization, i.e., self-assembly, functional materials. Here, we monitor real-time self-assembly dynamics at single nanoparticle level, which reveal marked similarities foundational principles of polymerization. Specifically, using...
An understanding of how complex nanoscale morphologies emerge from synthesis would offer powerful strategies to construct soft materials with designed structures and functions. However, these kinds have proven difficult characterize, therefore manipulate, because they are three-dimensional (3D), nanoscopic, often highly irregular. Here, we studied polyamide (PA) membranes used in wastewater reclamation as a prime example this challenge. Using electron tomography quantitative morphometry,...
We propose the depletion sphere model to explain control of valency when forming Au–Ag satellite nanostructures.
In various domains spanning materials synthesis, chemical catalysis, life sciences, and energy materials, in situ transmission electron microscopy (TEM) methods exert a profound influence. These methodologies enable the real-time observation manipulation of gas-phase liquid-phase reactions at nanoscale, facilitating exploration pivotal reaction mechanisms. Fundamental research areas like crystal nucleation, growth, etching, self-assembly have greatly benefited from these techniques....
Surface-enhanced Raman scattering (SERS) is a promising analytical technique with applications in environmental monitoring, healthcare, and the biopharmaceutical industry. While SERS has been successfully applied to molecules such as 4-mercaptobenzoic acid other thiol- amine-containing compounds, there limited research on its detection capabilities for rich carboxyl groups or unsaturated bonds, citric acid. This study investigates enhancement of Au@Ag core-shell nanoparticles response bonds....
The origin of selectivity in the hollowing silica nanoparticles is investigated to further understand silica. It realized that, during synthesis, precursors are essentially ion‐paired polyelectrolytes, whose nucleation depends on concentration counter ions, and most importantly, size/length poly(silicic acid). Thus, “silica” that nucleates out at different stages synthesis has degrees ion doping, which explains its solubility water, microporosity, selective etching phenomena. water shown be...
Reconfigurable hybrid nanoparticles made by decorating flexible polymer shells on rigid inorganic nanoparticle cores can provide a unique means to build stimuli-responsive functional materials. The shell reconfiguration has been expected depend the local core shape details, but limited systematic investigations have undertaken. Here, two literature methods are adapted coat either thiol-terminated polystyrene (PS) or polystyrene-poly(acrylic acid) (PS-b-PAA) onto series of anisotropic gold...
World's smallest screws with helical threads are synthesized via mild etching of Ag nanowires. With detailed characterization, we show that this nanostructure arises not from the transformation initial lattice, but result a unique mode. Three-dimensional printed models used to illustrate evolution etch pits, which possible mechanism is postulated.
Amphiphilic block copolymers such as polystyrene-block-poly(acrylic acid) (PSPAA) give micelles that are known to undergo sphere-to-cylinder shape transformation. Exploiting this polymer property, core-shell nanoparticles coated in PSPAA can be "polymerized" into long chains following the chain-growth polymerization mode. This method is now extended include a variety of different nanoparticles. A case study on assembly process was carried out understand influence PAA length, surface ligand,...
