  • What Are Refractory Metals?
    In some instances the weights are made in the form of screws which are adjusted to achieve balancing . One of the most significant uses of tungsten heavy metals is in radiation shielding which utilizes the high density of these alloys to attenuate gamma- and x-rays.
  • BUILDING MATERIAL FROM WASTE
    The major waste constituents were LDPE (low density polyethylene), HDPE ( high density polyethylene) and PS (polystyrene) which together comprised about 80% of the total waste. Small fractions of PET (polyethylene terephthalate) and PVC (polyvinyl chloride) were also present at a weight percentage of 10-15%, while the remaining balance contained other minor waste constituents such as paper, wood, cardboard, food scraps, cloth fragments and small metal chips.
  • Traceability of mass in air to mass in vacuum: results on the correlation between the change in mass and the surface chemical state
    In addition to regular stainless weight steel, we used copper artefacts with a protective noble- metal coating such as gold and rhodium. Materials for the use in watt balance experiments have to fulfil high requirements [45, 46] with respect to the stability of mass and the material properties such as hardness, density and magnetic susceptibility.

  • Aerosol‐Assisted Heteroassembly of Oxide Nanocrystals and Carbon Nanotubes into 3D Mesoporous Composites for High‐Rate Electrochemical Energy Storage
    As we known, oxide electrode materials possess high capacity; however, they are difficult to provide their electrodes high energy density mainly due to the slow ion diffusion and poor … … the transport resistances, enabled excellent energy density with a balanced power performance. Such performance of this asymmetric superca- pacitor exceeded that of PbO2 prototypes and other metal oxide based hybrid systems (the mass of the electrode mate- rials was estimated to be 40% of the total device weight ).[46] It also outperformed the state …
