“…The growth of Si NWs by floating catalyst chemical vapor deposition (FCCVD), as this method is known, is inherently faster than conventional CVD by three orders of magnitude. [ 28 ] Fast growth kinetics and a transformation process in a flow‐through reactor similar to those used in industrial kton/yr production of nanoparticle commodities argue in favor of the scalability of this manufacturing method.…”

Combined with other materials and device improvements, Si anodes can provide a step change in Lithium‐ion battery properties, enabling cell energy density to exceed 400 Wh kg−1. Freestanding, large‐area anodes of 100% Si produced by a slurry‐free method without carbon or binders are introduced. Their structure, a dense network of interconnected high aspect ratio Si nanowires (Si NWs), is analogous to a nanotextile and provides handling like paper. In conventional liquid electrolytes, the anode capacity is 2500 mAh g−1 at high mass loadings (e.g., 6.6 mAh cm−2), and cycling stability is 76% after 200 deep cycles, and 100% after 1800 cycles when cycled at 1000 mAh g−1. The nanowire network structure reduces junction resistance between particles and prevents any pulverization upon cycling. Combined impedance and composition‐selective electron microscopy demonstrate that capacity fading is exclusively through the progressive increase of SEI thickness and resistance. Full cell capacity with NMC811 translates into an energy density of 420 Wh kg−1 at the true cell level.

“…Due to the CNTs entangling themselves, the individual catalyst nanoparticles are less likely to agglomerate due to steric hindrance, and thus preventing unwanted larger CNTs from growing. Although such a growth phenomenon promotes uniformity of catalyst size distribution, it is not however conducive to uniform orientation and a well‐ordered film growth of VACNTs as otherwise seen on substrates [227,228] . The abovementioned growth mechanism of concurrent in situ catalyst formation and CNT growth can be adapted instead to form high‐quality aligned films upon a substrate of choice.…”

Nanowire‐like materials exhibit distinctive properties comprising optical polarisation, waveguiding, and hydrophobic channelling, amongst many other useful phenomena. Such 1‐D derived anisotropy can be further enhanced by arranging many similar nanowires into a coherent matrix, known as an array superstructure. Manufacture of nanowire arrays can be scaled‐up considerably through judicious use of gas‐phase methods. Historically, the gas‐phase approach however has been extensively used for the bulk and rapid synthesis of isotropic 0‐D nanomaterials such as carbon black and silica. The primary goal of this review is to document recent developments, applications, and capabilities in gas‐phase synthesis methods of nanowire arrays. Secondly, we elucidate the design and use of the gas‐phase synthesis approach; and finally, remaining challenges and needs are addressed to advance this field.

Multifunctional wearable heaters have attracted much attention for their effective applications in personal thermal management and medical therapy. Compared to passive heating, Joule heating offers significant advantages in terms of reusability, reliable temperature control, and versatile coupling. Joule‐heated fabrics make wearable electronics smarter. This review critically discusses recent advances in Joule‐heated smart fabrics, focusing on various fabrication strategies based on material‐structure synergy. Specifically, various applicable conductive materials with Joule heating effect are first summarized. Subsequently, different preparation methods for Joule heating fabrics are compared, and then their various applications in smart clothing, healthcare, and visual indication are discussed. Finally, the challenges faced in developing these smart Joule heating fabrics and their possible solutions are discussed.

Gas-to-nanotextile: high-performance materials from floating 1D nanoparticles

Abstract: Suspended in the gas phase, 1D inorganic nanoparticles (nanotubes, nanowires) grow to hundreds of microns in a second and can be thus directly assembled into freestanding network materials. The corresponding...
