2D transition metal dichalcogenides (TMDCs) are nanomanufactured using a generalized strategy with self-assembled DNA nanotubes. DNA nanotubes of various lengths serve as lithographic etch masks for the dry etching of TMDCs. The nanostructured TMDCs are studied by atomic force microscopy, photoluminescence, and Raman spectroscopy. This parallel approach can be used to manufacture 2D TMDC nanost...

Carbon nanotube (CNT)-based piezoresistive strain sensors have the potential to outperform traditional silicon-based piezoresistors in MEMS devices due to their high strain sensitivity. However, the resolution of CNT-based piezoresistive sensors is currently limited by excessive 1/f or flicker noise. In this paper, we will demonstrate several nanomanufacturing methods that can be used to decrea...

Robust nanomanufacturing methodologies are crucial towards realizing simple and cost-effective products. Here we discuss nanofabrication of ordered metal nanoparticles through pulsed-laser-induced self-organization. When ultrathin metal films are exposed to short laser pulses, spontaneous pattern formation results under appropriate conditions. Under uniform laser irradiation two competing modes...

With the rapid and continuous development of nanomanufacturing technology, demands for both large range high precision metrology structured surfaces are becoming increasingly urgent. This paper proposes a metrological measurement system based on commercial atomic force microscope. By using nano-positioning platform from SIOS, expands 110 μm × 20 to 25 mm 5 mm. A signal amplifier with low noise ...

A multiscale model of atomic layer deposition (ALD) inside a nanoporous material is developed in this paper. The overall model couples lattice Monte Carlo simulators describing molecular-scale growth of the ALD film to a continuum description of the precursor transport within the nanopore. The multiscale simulator is used to study how intra-pore precursor depletion leads to nonuniform ALD films...

Classical manufacturing techniques of advanced polymeric fibers rely on a combination of high polymer crystallinity and high degree of macromolecular alignment to achieve superior mechanical properties. As a consequence, advanced polymeric fibers such as Kevlar and Spectra possess extraordinary strength, but low strains to failure and toughness (energy absorption during rupture). Recent analysi...

We report the design, fabrication, and characterization of planar arrays of externally-fed silicon electrospinning emitters for high-throughput generation of polymer nanofibers. Arrays with as many as 225 emitters and with emitter density as large as 100 emitters cm(-2) were characterized using a solution of dissolved PEO in water and ethanol. Devices with emitter density as high as 25 emitters...

Understanding and manipulating synthesis reactions and crystal growth mechanisms are keys to designing and constructing the morphology and functional properties of advanced materials. Herein, the morphology-controlled synthesis of three-dimensional (3D) ZnO nanoforests is reported via a facile hydrothermal route. Specifically, the respective and synergistic influence of polyethylenimine (PEI) a...
