Significance Spontaneously formed nanoblisters are almost inevitable when transferring 2D crystals to a substrate. We hypothesize that those filled with liquid according our time-lapse atomic force microscopy scans and reasonable estimation of adhesion energy. show the liquid-filled form as result competition between elastic energy deformed crystal, interfacial associated van der Waals interactions, surface tension contents. Besides pointing solutions for controlling their shape internal...

Abstract Molecular sieving may occur when two molecules compete for a nanopore. In nearly all known examples, the nanopore is larger than molecule that selectively enters pore. Here, we experimentally demonstrate ability of single-wall carbon nanotubes with van der Waals pore size 0.42 nm to separate n-hexane from cyclohexane—despite fact both have kinetic diameters rigid This unexpected finding challenges our current understanding selectivity and how enter tight channel. Ab initio molecular...
Abstract Indistinguishable single photons in the telecom-bandwidth of optical fibers are indispensable for long-distance quantum communication. Solid-state photon emitters have achieved excellent performance key benchmarks, however, demonstration indistinguishability at room-temperature remains a major challenge. Here, we report telecom wavelengths from individual nanotube defects fiber-based microcavity operated regime incoherent good cavity-coupling. The efficiency coupled system...
Abstract Flexible transparent conductors are an enabling component for large‐area flexible displays, wearable electronics, and implantable medical sensors that can wrap around move with the body. However, conventional conductive materials decay quickly under tensile strain, posing a significant hurdle functional devices. Here, we show high electrical conductivity, mechanical stretchability, optical transparency be simultaneously attained by compositing long metallic double‐walled carbon...
Bismuth is a lithium-ion battery anode material that can operate at an equilibrium potential higher than graphite and provide capacity twice as high of Li4Ti5O12, making it intrinsically free from lithium plating may cause catastrophic failure. However, the bismuth hampered by its inferior cyclability (limited to tens cycles). Here, we propose "ion conductive solid-state matrix" approach address this issue. By homogeneously confining nanoparticles in γ-Li3PO4 matrix electrochemically formed...

Attaining aqueous solutions of individual, long single-walled carbon nanotubes is a critical first step for harnessing the extraordinary properties these materials. However, widely used ultrasonication–ultracentrifugation approach and its variants inadvertently cut into short pieces. The process also time-consuming difficult to scale. Here we present an unexpectedly simple solution this decade-old challenge by directly neutralizing nanotube-chlorosulfonic acid in presence sodium...

ABSTRACT Conductive hydrogels with ionic compounds possess great potential for the development of soft smart devices. A dielectric scarfskin is typically required these devices to prevent short circuiting, leading lower stretchability than hydrogel. Henceforth, commonly used materials, such as PDMS and Ecoflex, cannot be largely stretched. Hydrogel ultrastretchability are accommodate hostile application environments. Herein, we propose a hydrogel fiber coated layer that can stretched over...

Herein, a stretchable sensor based on highly conductive ionic gel is developed. Different phosphor nanoparticles uniformly embedded into enable color‐customization...
Aryl diazonium reactions are widely used to covalently modify graphitic electrodes and low-dimensional carbon materials, including the recent creation of organic color centers (OCCs) on single-wall nanotube semiconductors. However, due experimental difficulties in resolving small functional groups over extensive lattices, a basic question until now remains unanswered: what group, if any, is pairing with aryl sp3 defect when breaking C═C bond sp2 lattice? Here, we show that water plays an...

Surfactants, molecular surface-active agents, are widely used to stabilize single-walled carbon nanotubes (SWCNTs) and many other nanomaterials in water facilitate solution processing device integration. However, it is notoriously difficult cleanly remove surfactants when they no longer needed. Even high-temperature thermal annealing leaves residues that can degrade the otherwise remarkable electrical optical properties of SWCNTs. Moreover, damages smaller-diameter (<1 nm) due aggressive...
