    Universal paradigm of ternary metacomposites with tunable epsilon-negative and epsilon-near-zero response for perfect electromagnetic shielding

    CaCu3Ti4O12 (CCTO) ceramic nanocomposites incorporating graphene–carbon black (GRCB) fillers were fabricated by spark plasma sintering process. The percolative effects of conductive GRCB fillers on dielectric res...

    Interaction of cemented carbide micro-drills and printed circuit boards during micro-drilling

    Cemented carbide micro-drills (0.1 to 0.3 mm in diameter) wear down or break casually while drilling micro-holes in printed circuit boards (PCBs). This study focused on the interaction between cemented carbide...
