“…VGCNFs were prepared by a floating catalyst vapour‐deposition method. This preparation technique results in the production of partitioned, stacked nanocones or partitioned nanotubes, all of which contain a hollow interior cavity . Fibre lengths can extend up to 20 μm with an outer tube diameter of ∼100 nm, similar to multi‐walled nanotubes.. All solutions were prepared with Milli‐Q water (resistivity = 18.2 MΩ·cm).…”

Composite ionic-covalent entanglement (ICE) hydrogel networks were prepared from poly(N-isopropylacrylamide), alginate, and carbon nanofibres. An optimised triple network hydrogel with 86% water content exhibited a compressive strength of 3.0 6 0.1 MPa and 66 6 13 mS/cm electrical conductivity. Thermal actuation was shown to have a shorter response time for gels containing nanofibres, compared to those which did not and hydrogel samples more than halved in volume within 1 minute when placed in a 60 8C water bath. Controlled dye release was demonstrated as a potential application and used to further quantify thermal actuation over short times. Joule heating techniques were used to electronically actuate the hydrogel samples, removing the traditional requirements for immersion in a temperature controlled liquid. It is expected that devices based on these materials will find potential applications in soft robotics and micro fluidics.

“…Our interest in covering problems is motivated by packing particles arising in science and engineering applications. Packing problems are widely used in modeling liquid and glass structures [1,2], representing granular materials [3], packing beds, and cermet [4], as well as in many other applications (see, e.g., [5][6][7][8][9][10]). Many algorithms have been proposed for packing spherical particles (see, e.g., [11][12][13][14][15][16] and the references therein).…”

“…Among the different shapes used to represent the microstructure of non-spherical particles, the spheroid (ellipsoid of revolution) is one of the most frequently used (see, e.g., [5][6][7][8]10]). One of the reasons to use the spheroid is its relative simplicity comparing to the general ellipsoid.…”

Covering spheroids (ellipsoids of revolution) by different spheres is studied. The research is motivated by packing non-spherical particles arising in natural sciences, e.g., in powder technologies. The concept of an ε -cover is introduced as an outer multi-spherical approximation of the spheroid with the proximity ε . A fast heuristic algorithm is proposed to construct an optimized ε -cover giving a reasonable balance between the value of the proximity parameter ε and the number of spheres used. Computational results are provided to demonstrate the efficiency of the approach.

“…10 CNTs are a type of highly efficient nanometer TDS displaying adequate adsorption activity that have considerable potential as anticancer drugs with high selectivity for tumor sites. 11,12 Recent in vitro studies have shown that CNTs internalize into mammalian cells easily, effectively transporting molecular cargo into the cytoplasm and potentially nucleus. [13][14][15][16] CNTs mainly comprise multiple coaxial tubes composed of hexagonal carbon atoms.…”

Nanoparticle drug formulations have enormous application prospects owing to achievement of targeted and sustained release drug delivery, improvement in drug solubility and reduction of adverse drug reactions. Recently, a variety of efficient drug nanometer carriers have been developed, among which carbon nanotubes (CNT) have been increasingly utilized in the field of cancer therapy. However, these nanotubes exert various toxic effects on the body due to their unique physical and chemical properties. CNT-induced toxicity is related to surface modification, degree of aggregation in vivo, and nanoparticle concentration. This review has focused on the potential toxic effects of CNTs utilized as anti-tumor drug carriers. The main modes by which CNTs enter target sites, the toxicity expressive types and the factors affecting toxicity are discussed.
