In an effort to develop a cost-efficient technology for wireless high-temperature surface acoustic wave sensors, this study presents an evaluation of a combined method that integrates physical vapor deposition with electroless deposition for the fabrication of platinum-based planar antennas. The proposed manufacturing process becomes attractive for narrow, thick, and sparse metallizations for antennas in the MHz to GHz frequency range. In detail, narrow platinum-based lines of a width down to 40 μm were electroless-deposited on γ-Al 2O 3 substrates using different seed layers.

Nickel⁻manganese⁻cobalt oxides, with LiNiMnCoO₂ (NMC) as the most prominent compound, are state-of-the-art cathode materials for lithium-ion batteries in electric vehicles. The growing market for electro mobility has led to a growing global demand for Li, Co, Ni, and Mn, making spent lithium-ion batteries a valuable secondary resource. Going forward, energy- and resource-inefficient pyrometallurgical and hydrometallurgical recycling strategies must be avoided.

Since the optimum 25-OH-D3 serum levels for NK cell-mediated antibody-dependent cellular cytotoxicity (ADCC) are unknown, we determined the 25-OH-D3 serum levels associated with maximum NK cell-mediated ADCC. CD20 antibody-loaded CD20 B-cell lymphoma cell lines were cultured with NK cells and ADCC activity was determined by lactate dehydrogenase release assays.

Infections with B. cenocepacia are very difficult to treat due to their high intrinsic resistance to most antibiotics.
