Uniform CuS nanotubes of 30–90 nm in inner diameter and 20–50 thickness, can be synthesized large quantities by a facile solution reaction at 80 °C ethylene glycol using Cu nanowires as sacrificial templates choosing suitable sulfur sources for the sulfuration reaction, where solvent played crucial roles formation well-defined nanotubes. The results demonstrated that such thiourea thiacetamide which release ionic rather than molecular their decomposition temperature are favorable nanotubes,...
Complex materials science problems such as glass formation must consider large system sizes that are many orders of magnitude too to be solved by first-principles calculations. The successful application machine learning (ML) in various other fields suggests ML could useful address complex science. To test its efficacy, we attempt predict bulk metallic using ML.

Materials with asymmetric structures are attractive for wide applications in chemistry and materials science. Two-dimensional Janus disks or nanosheets particularly appealing because of the unique shape distinctive self-assembled structures.

Colloidal InP quantum dots (QDs) have emerged as potential candidates for constructing nontoxic QD-based optoelectronic devices. However, charge transport in QD thin-film assemblies has been limitedly explored. Herein, we report the synthesis of ∼8 nm edge length (∼6.5 height), tetrahedral QDs and study thin films using platform field-effect transistor (FET). We design a hybrid ligand-exchange strategy that combines solution-based exchange with S2– solid-state N3– to enhance interdot...
Large-scale, controlled fabrication of ordered phases is challenging at the nanoscale, yet highly demanded as their well-ordered structure and chemistry key for advanced functionality.

For nanostructures in advanced electronic and plasmonic systems, a single-crystal structure with controlled orientation is essential. However, the fabrication of such devices has remained challenging, as current nanofabrication methods often suffer from either polycrystalline growth or difficulty integrating single crystals substrates desired orientations locations to create functional devices. Here we report thermomechanical method for nanowire arrays, which enables simultaneous synthesis,...
Nanofabrication techniques are limited by at least one of the required characteristics such as choice material, control over geometry, fabrication requirements, yield, cost, and scalability. Our previously developed method thermomechanical nanomolding fulfills these although it requires high processing temperatures.

Abstract The underlying atomistic mechanism of deformation is a central problem in mechanics and materials science. Whereas crystalline metals fundamentally understood, the understanding amorphous lacks behind, particularly identifying involved temporal spatial scales. Here, we reveal that at small scales size-dependent behavior significantly deviates from homogeneous flow, exhibiting increasing rate with reducing size gradually shifted composition. This transition suggests changes...
Addressing complex materials science problems through machine learning (ML) is challenging. A primary reason for the challenge that underlying controlling mechanisms may vary within considered problem space. To quantify this, we divide alloy data into subgroups and construct ML models to predict metallic glass formation. We discover subgrouping guided by physical insights leads significantly higher prediction accuracy. Specifically, when applying Inoue's subgrouping, specific outperform...
