High-performance volatile organic compounds free silica-filled butadiene rubber green nanocomposites using ionic liquid peroxide vulcanization Open
Manufacturing green rubber nanocomposites with higher performance and without volatile organic compounds (VOCs) is a big bottleneck for academics and the industry. Bis(3-triethoxysilylpropyl) tetra sulfide or Si69 silane is the most common…

Broadband measurements of the surface impedance in ferromagnetic wires as a boundary condition for scattering problems Open
In the cm-wave range, the skin depth is comparable to the micron radius of ferromagnetic wires and thus their magnetic and conductive properties will influence the scattered electromagnetic field. Solving the scattering problem by consider…
