Graphene is still in search of its killer application that delivers a unique value proposition or a first mover advantage. In the absence of such applications, the commercialisation process remains a substitution game. This is not meritless as graphene can target a broad spectrum of applications including energy storage, composites, functional inks and electronics. The value proposition of graphene, the competitive landscape, the technical requirements, and the likely graphene manufacturing techniques will be different for each sector, resulting in market fragmentation. Therefore, the graphene market will in fact grow to consist of multiple subsets.

while Electrical market applications decreased 6.7% in 2014.

Foldable, high-performance copper cable saves space in the rack High-performance, low-cost passive copper cabling remains the preferred alternative for short-reach applications in the data center.

High-performance, low-cost passive copper cabling remains the preferred alternative for short-reach applications in the data center. However, standard round copper cables can be bulky and consume precious space. A recent innovation in manufacturing technology by 3M has resulted in the development of a uniquely shielded, thin, ribbon-style copper cable. The cable has the ability to fold multiple times and maintain signal integrity, allowing for higher-density racks and space savings. A major barrier to decreasing the size and stiffness of a round cable is inherent in the construction of traditional cable. This is an issue because a round copper cable can extend up to nine inches when routed behind a cabinet. In conventional, twin axial constructions, the shield is applied by wrapping it spirally around the insulated wire pair. This layer is then overwrapped to provide support and retain the primary shield wrap, increasing the stiffness of the pair. Multiple pairs are then cabled and an overall foil and braided shield are typically applied, thus further increasing the cable bulk and stiffness.

Strengthening a record number (98) of the company's main power distribution lines. Replacing thousands of distribution utility poles with stronger ones - most of them concrete - designed to withstand hurricane-force wind gusts of 130 mph or more. Installing additional smart grid technology to better detect and address power outages, and adding improved lightning protection equipment. Upgrading FPL's power transmission system. Replacing wood poles with concrete structures and upgrading associated hardware. Installing new flood monitoring systems at select power substations that are most susceptible to possible flooding and storm surge.

These results verify that the developed DC superconducting cable is reliable and fulfils all the requirements necessary for successful use in various power applications including railway systems.

Applications for superconducting wires, which carry electricity without resistance when cooled to a critical temperature, include underground transmission cables, transformers and large-scale motors and generators. But these applications require wires to operate under different temperature and magnetic field regimes.  

Copper ranks second to silver as an electrical conductor. The copper cladding of LEONI Histral® H16 ensures a good electrical conductivity whenever mechanical properties do not play a primary role.

High-frequency (HF) technology In HF technology the so-called „skin effect“ ensures that the current flow is restricted to a very thin layer situated on the surface of the conductor and that the overall resistance in the conductor is reduced. LEONI Histral® H16 has copper, which features good electrical, in the cladding only. The additional galvanic plating of the surface causes the skin effect to be optimized. Aeronautics and automotive technology Weight is of major importance for the construction of airplanes and automobiles. LEONI Histral® H16 is particularly suited for larger cross-sections here that can be employed for the transmission of power, where there is a significant weight reduction potential. Shielding braids LEONI Histral® H16 features a resistivity lending itself well to shielding braids because high coverage can be achieved at a comparatively low weight. The fact that aluminum suffers from the drawback of having a poor contact resistance is largely offset by the copper cladding. Heating applications The combination of a relatively good resistance value with a rather low mechanical resilience suggest that LEONI Histral® H16 may well be used in all kinds of heating applications that are not exposed to a permanently varying level of stress.

In fact, the researchers are already working with industry to exploit the results for specific wear resistant applications. While designing wear resistant materials is not a trivial undertaking, with many additional factors coming into play such as corrosion resistance, thermal stability and cost, they believe there are no critical limitations to the new approach.
