Monitoring of human bodily motion requires wearable sensors that can detect position, velocity and acceleration. They should be cheap, lightweight, mechanically compliant display reasonable sensitivity at high strains strain rates. No reported material has simultaneously demonstrated all the above requirements. Here we describe a simple method to infuse liquid-exfoliated graphene into natural rubber create conducting composites. These materials are excellent displaying 104-fold increases in...
Two-dimensional titanium carbide (Ti3C2Tx), or MXene, is a new nanomaterial that has attracted increasing interest due to its metallic conductivity, good solution processability, and excellent energy storage performance. However, Ti3C2Tx MXene flakes suffer from degradation through oxidation prolonged exposure oxygenated water. Preventing the occurrence of oxidation, i.e., formation TiO2 particles, was found be crucial in maintaining quality. In present work, we freezing aqueous dispersions...
High quality opal-like photonic crystals containing graphene are fabricated using evaporation-driven self-assembly of soft polymer colloids. A miniscule amount pristine within a colloidal crystal lattice results in the formation with strong angle-dependent structural color and stop band that can be reversibly shifted across visible spectrum. The mechanically deformed or change as function their temperature, hence sensitive mechanochromic thermochromic response make them attractive candidates...
A significant reduction in the electrical percolation threshold is achieved by locking carbon nanotubes (CNTs) a predominantly hexagonally close-packed (HCP) colloidal crystal lattice of partially plasticized latex particles. Contrary to other widely used processing where CNTs are randomly distributed within matrix, for first time, we show that excluding from occupying interior volume particles promotes formation nonrandom segregated network. The four times lower an ordered network made with...
Ultrasonication is the most widely used technique for dispersion of a range nanomaterials, but intrinsic mechanism which leads to stable solutions poorly understood with procedures quoted in literature typically specifying only extrinsic parameters such as nominal electrical input power and exposure time. Here we present new insights into representative nanomaterial, single-walled carbon nanotubes (SW-CNTs), using novel up-scalable sonoreactor an situ measurement acoustic cavitation activity...
Abstract Graphene and other graphitic materials are suggested as a route to cheap, high‐performance, environmentally‐sustainable electronic devices owing their almost unique combination of properties. Liquid‐phase exfoliation is family shear‐based techniques that produce dispersions nanosheets from bulk layered material crystallites. High‐quality graphene can be produced in solvents or surfactant dispersions; however the lateral size these sheets limits network transport properties observed...
2D materials, given their form-factor, high surface-to-volume ratio, and chemical functionality have immense use in sensor design. Engineering heterostructures can result robust combinations of desirable properties but design methodologies require careful considerations about material orientation to maximize response. This study introduces a approach that combines the excellent electrical transport transduction graphite film with reactivity derived from edge sites semiconducting molybdenum...
We report on the first use of carbon-nanotube-based films to produce crystals proteins. The nucleate surface film. difficulty crystallizing proteins is a major bottleneck in determination structure and function biological molecules. crystallization two model medically relevant was studied. Quantitative data times protein lysozyme are also presented. Two types nanotube films, one made with surfactant Triton X-100 (TX-100) gelatin, were tested. Both induce nucleation crystal phase at...
Transparent and electrically conductive metal nanowire networks are possible replacements for costly indium tin oxide (ITO) films in many optoelectronic devices. ITO regularly patterned using pulsed lasers so similar technologies could be used coatings to define electrode structures. Here, the effects of laser irradiation on conducting silver simulated then investigated experimentally formed by spray deposition onto transparent substrates. The ablation threshold fluence is found such related...
Silver nanowire coatings are an attractive alternative to indium tin oxide for producing transparent conductors. To fabricate with low sheet resistance required touchscreen displays, a multi‐layer network of silver nanowires must be produced that may not cost effective. This problem is counteracted here by modifying the electrical properties ultra‐low‐density through local deposition conducting graphene platelets. Unlike other solution‐processed materials, such as oxide, our pristine free...
Here we show an industrially scalable and inexpensive method of fabricating entirely synthetic, non-xenogeneic carbon nanotube-based scaffolds by vacuum filtration for the culture human embryonic stem cells. We that controlled exposure nanotubes to sonication amount energy delivered dispersion directly impacts surface properties, allowing control over nanotopography resulting nanotube films, which in turn has demonstrable effects upon vitro cells cultures. By altering processing conditions...
Flexible, free-standing transparent conducting electrodes (TCEs) with simultaneously tunable transmittances up to 98% and sheet resistances down 11 Ω/sq were prepared by a facile spray-coating method of silver nanowires (AgNWs) onto dry-spun multiwall carbon nanotube (MWNT) aerogels. Counterintuitively, the transmittance hybrid can be increased as mass density AgNWs within MWNT aerogels increases; however, final achievable depends on initial transparency Simultaneously, strong decrease in...
Abstract Here, an approach is presented to incorporate graphene nanosheets into a silicone rubber matrix via solid stabilization of oil‐in‐water emulsions. These emulsions can be cured discrete, graphene‐coated balls or continuous, elastomeric films by controlling the degree coalescence. The electromechanical properties resulting composites as function interdiffusion time and loading level are characterized. With conductivities approaching 1 S m −1 , elongation break up 160%, gauge factor...
Nanodiamond – functionalised with oligoglycine is used as a novel Pickering emulsion stabiliser, offering high retention on bovine cornea tissue via mucoadhesion.
Here we present a route for non-covalent functionalization of carboxylated multi-walled carbon nanotubes and graphene oxide with novel two-dimensional peptide assemblies. We show that self-assembled amino-terminated biantennary tetraantennary oligoglycine peptides (referred to as tectomers) effectively coat also strongly interact due electrostatic interactions hydrogen bonding the driving force, respectively. The resulting hybrids can be made into free-standing conducting composites or...
Nanoparticles of cerium dioxide (or nanoceria) are interest because their oxygen buffering, photocatalytic ability, and high UV absorption. For applications, the nanoceria can be incorporated into a polymer binder, but questions remain about link between nanoparticle distribution resulting nanocomposite properties. Here, thermal, mechanical, optical properties polymer/ceria nanocomposites correlated with nanostructures. Specifically, made from waterborne Pickering particles shells compared...
Natural materials, such as bone and spider silk, possess remarkable properties a result of sophisticated nanoscale structuring. They have inspired the design synthetic materials whose structure at is carefully engineered or where nanoparticles, rods wires, are self-assembled. Although much work has been done in recent years to create ordered structures using diblock copolymers template-assisted assembly, no reports describe highly ordered, three-dimensional nanotube arrays within polymeric...
