Chalk One Up for the Little Guy in the Big Business of Nanotech

Oxonica sells its energy division to inventor of diesel fuel additive

1 min read

I have followed with a mix of bemusement and pity the long slow downward spiral of Oxonica. The final denouement, if you will, was Oxonica selling Oxonica Energy Limited to Energenics Holdings Pte, the company that they tried to stiff arm out of paying royalty fees to and then attempted to hold up in a prolonged legal battle, which they ultimately lost leading to this sale.

This is not a sad story, however, because now the inventor of the fuel additive that makes diesel fuels run more efficiently, Ronen Hazarika, CEO of Energenics, will be taking over the business. And it seems by using the original nano-enabled formula Energenics' product has proven quite effective in increasing diesel fuel efficiency.

While this may mark the end of this story, it is not quite the epilogue, and as TNTLog has pointed out we may yet see some interesting parts of this story revealed over time.

3D-Stacked CMOS Takes Moore’s Law to New Heights

When transistors can’t get any smaller, the only direction is up

Perhaps the most far-reaching technological achievement over the last 50 years has been the steady march toward ever smaller transistors, fitting them more tightly together, and reducing their power consumption. And yet, ever since the two of us started our careers at Intel more than 20 years ago, we’ve been hearing the alarms that the descent into the infinitesimal was about to end. Yet year after year, brilliant new innovations continue to propel the semiconductor industry further.

Along this journey, we engineers had to change the transistor’s architecture as we continued to scale down area and power consumption while boosting performance. The “planar” transistor designs that took us through the last half of the 20th century gave way to 3D fin-shaped devices by the first half of the 2010s. Now, these too have an end date in sight, with a new gate-all-around (GAA) structure rolling into production soon. But we have to look even further ahead because our ability to scale down even this new transistor architecture, which we call RibbonFET, has its limits.
