• Researchers develop underwater app for divers
  • Silex tests first full-scale laser for GLE’s pilot facility in the US
  • Nitro Software rejects unsolicited takeover bid from Potentia


Instead of using hand signals, there’s now new way for scuba divers to communicate underwater called the AquaApp.

Researchers at the University of Washington have developed a method that allows any of the billions of smartphones around the world to act as an acoustic-based messenger and networking device for use underwater.

“Smartphones rely on radio signals like Wi-Fi and Bluetooth for wireless communication. Those signals don’t propagate well underwater, but acoustic signals do,” co-lead author and doctoral student Tuochao Chen said.

“With AquaApp, we demonstrate underwater messaging using the speaker and microphone widely available on smartphones and smartwatches. 

“Other than downloading an app on their phone, the only thing people will need is a waterproof phone case rated for the depth of their dive.”

Don’t worry divers, you don’t have to learn anything new.

The system enables users to select from a list of 240 pre-set messages that correspond to hand signals – with the 20 most common signals are prominently displayed on the screen and easily accessible.

Silex has successfully tested the first full-scale laser system module developed for deployment in Global Laser Enrichment’s (GLE) commercial pilot demonstration facility in the US – with the system expected to be installed by the end of CY2022.

“This is a pivotal milestone for the SILEX uranium enrichment technology which demonstrates the ability of our laser systems to operate reliably at commercial-scale for extended periods,” CEO and MD Michael Goldsworthy says.

GLE is planning to complete the commercial pilot demonstration project by the mid-2020s, after which a feasibility assessment will be conducted for the proposed Paducah Laser Enrichment Facility (PLEF). 

GLE hopes to deploy the PLEF for the production of natural grade uranium (in the form of UF6) in the late 2020s via enrichment of the US Department of Energy (DOE)-owned tails inventories under a landmark agreement signed between GLE and the DOE in 2016. 



Nitro’s board has unanimously rejected an unsolicited, highly conditional, and non-binding indicative proposal from private equity firm, Potentia Capital Management Pty Ltd, together with its co-investor HarbourVest Partners, LLC (Potentia Consortium), to acquire 100% of the issued share capital of Nitro at A$1.58 cash per share. 

The Potentia Consortium has advised Nitro that it has acquired a combined relevant and economic interest in more than 41.4m Nitro shares, which represents 17.0% of the issued share capital in Nitro. 

The board said the proposal doesn’t adequately compensate shareholders for “Nitro’s position as one of only two software companies worldwide with a proven enterprise-grade SaaS PDF productivity and eSigning platform, and a uniquely powerful and differentiated solution offering in a fast-growing global market worth US$28 billion.” 

Plus, it represents a 61% discount to Nitro’s 52-week high trading price of $4.00 per share on 17 November 2021 and a 19% discount to the median broker target price of $1.95 per share.

The AI recruitment player has officially launched its platform with the completion of the Shortlistmii module, Phase One of its commercialisation roadmap in the Aussie recruitment industry, which generates revenue of $16.4 billion but has “struggled with innovation and change,” the company says. 

MD Andrew Hornby said the AI provides complex candidate-to-job matching and ranking by using accurate semantic matching powered by domain specific knowledge graphs.

“This capability improved on the traditional process of manual candidate database matching that is inefficient and potentially biased,” he said.
