The Grounding Impedance Calculation of Large Steel Grounding Grid
Energy Procedia, 2012 AbstractSteel is widely used as grounding material in China. The resistivity and permeability of steel are higher than those of copper. If a grounding grid is very large, it is a problem for steel grounding grid to have great potential difference within the grounding grid.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials
Advanced Engineering Materials, EarlyView.Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Determining of galvanically separated grounding grids and grounding systems
2000 10th Mediterranean Electrotechnical Conference. Information Technology and Electrotechnology for the Mediterranean Countries. Proceedings. MeleCon 2000 (Cat. No.00CH37099), 2005 A model for determination of galvanically separated grounding grids and grounding systems has been presented in this work. Determination of the above also means determination of the grounding resistances, the potentials of the grounding grids, currents of leading to earth from the separated electrodes, distribution of the potentials along the surface ...

Advanced Engineering Materials, EarlyView.Additive manufacturing (AM) allows great geometric freedom for lightweight components. As parts are progressively optimized exploiting potentials in AM leading in smaller material cross sections, high pressure solution treating and aging (STA) treatments show an enormous potential for strongly improving material properties.
