Not enough data
Jonathan Fernandez's focus on local sports, particularly football and basketball at South Dakota State University, suggests he would be most responsive to pitches related to these specific teams and their performances. These could include previews, predictions, or post-game analysis of significant matches.
Given the high percentage of announcement coverage in his articles, Jonathan may also be interested in news about coaching changes or player awards within the realm of South Dakota sports.
It's important for sources reaching out to Jonathan to have a deep understanding of the local sports scene in South Dakota and specifically Sioux Falls. They should tailor their pitches with this geographic focus in mind.

In this study, we investigated the frictional properties of TiB2 films produced by high-power impulse magnetron sputtering and compared them with those of TiN- and CrN-sputtered coatings also made using high-power pulsed discharges. The films were characterised by scanning electron microscopy, Electron Probe Micro-Analysis, nanoindentation and friction tests. Sliding friction analyses were performed against aluminium surfaces at different temperatures, ranging from room temperature to 300 °C. The TiB2 coatings exhibited hardness values of about 39 GPa, regardless of the bias potential used between −50 V and −100 V, a low modulus of around 300 GPa and a dense compact columnar microstructure with grain sizes between 51 and 68 nm in diameter. The friction behaviour on aluminium produced the transfer of this element to the films, at rates that depended on the test temperature. The TiN and CrN coatings exhibited low–medium adhesion to aluminium at room temperature and severe transfer during the friction tests at 150 °C. In the case of the TiB2 films, the adhesion of aluminium during friction tests was low for temperatures up to 175 °C. In fact, a clear transition of the mild-to-severe adhesion of aluminium on TiB2 was observed in the temperature range of 175 °C to 200 °C for the testing conditions evaluated in this study, which was concomitant with the evolution observed for the friction coefficients.
