Copper Electroplated TPMS Polymer Lattices for Lightweight Absorption Dominant Electromagnetic Interference Shielding

Advanced Materials Technologies, EarlyView.
Copper electroplating transforms lightweight 3D‐printed TPMS polymer lattices into effective electromagnetic shields. Topology, relative density, and conductive seed layer continuity govern copper penetration, electrical resistance, and attenuation. SEA consistently exceeds SER, while 35% RD Diamond lattice gives the best performance, reaching 48.72 dB

Inclusion Rating of Clean Steels

, 2009
  This report covers a study concerning the methods that are available for determining the cleanness level for steels. No outstanding method is available for rating clean steels, when clean steel is defined as free of fatigue initiating inclusions. Fatigue strength is to a large extent dependant of the biggest inclusion size in the stressed volume ...

Piezoresistivity Enhancement by Graphite Flake Alignment in Thin Composite Films for Dielectric Elastomer Switches

Advanced Robotics Research, EarlyView.
This article presents dielectric elastomer switch (DES) materials, based on composite thin films. Alignment of graphite flakes due to their physical confinement within the thin films lead to much stronger piezoresistive responses than bulk composites, while their durability exceeds that of conventional liquid‐based DES materials.

Greenhouse Gas Regulation under the Clean Air Act: A Guide for Economists [PDF]

Until recently, most attention to U.S. climate policy has focused on legislative efforts to introduce a price on carbon through cap and trade. In the absence of such legislation, the Clean Air Act is a potentially potent alternative.

The Effect of Ladle Treatment on Steel Cleanness in Tool Steels

, 2016
Syftet med denna studie var att få en överblick av verktygsståls renhet. Studier på tre olika stålsorter utfördes. Inneslutningsbilden under vakuumbehandling undersöktes. Resultaten är baserade på industriförsök likväl som termodynamiska beräkningar.
