Photochromic materials with rapid response and high stability are essential for progressive anti-counterfeiting and secure information encryption technologies. Herein, we report a Förster resonance energy transfer (FRET)-assisted strategy to boost the photochromic properties of high-crystalline C3N5 nanosheets (HC-C3N5) by integrating carbon dots (CDs). The incorporation of CDs significantly increased light absorption, fluorescence intensity, and energy transfer efficiency, leading to an ultrafast and reversible color transition from dark yellow to green under UV irradiation, with complete recovery within 180 s and excellent cycling stability. Transient photovoltage technique (TPV) test confirms a non-radiative energy transfer pathway between CDs and HC-C3N5, excluding the…

I like Agile. I like discipline. I like systems that ship and systems that learn. What I don’t like: tribes. In the last couple decades, many teams camped at the ends of a spectrum: Traditional shops treated optimization as virtue and adaptation as risk. Agile shops treated adaptation as virtue and optimization as betrayal. Both missed the point. By adaptation I mean fast learning and course-correction under uncertainty. By optimization I mean reliability and repeatability under constraints. The mistake is treating either one as a permanent operating mode. The adult question is: what should dominate right now? This is a…

The Campaign For Fairer Gambling (CFG) has issued a statement after Governor Janet Mills of Maine has reversed her intent to veto a bill to legalize online slots and casino games. While online sports betting is legal in Maine, online gambling has largely been illegal in the state. However, Gov Janet Mills has now allowed for the passage of the online casino bill LD1164. iGaming is coming to Maine. That's according to a statement released by Gov. Janet Mills earlier today. Based on the statement's wording, it appears she's letting it become law without her signature. pic.twitter.com/0GKMFjUlTC — Steve Bittenbender…

On January 6, 2026, PMG announced the acquisition of Digital Voices, an influencer marketing agency with teams across London, New York, and Costa Rica. The deal adds approximately 70 employees to PMG.  Digital Voices brings established creator program delivery expertise alongside proprietary tools designed to support more structured influencer operations, including centralized campaign management, benchmarking, and insight generation. PMG has positioned the acquisition as a capability acceleration move.  The acquisition can be interpreted as an effort to accelerate influencer capabilities rather than enter a new service line. Digital Voices adds established creator program operations and enabling capabilities that support more consistent influencer program execution and oversight.   For PMG, the strategic value appears to…

Dell’Oro Group VP Jeff Heynen told RCR that U.S. operators are being careful not to over-utilize their spectrum for FWA Disciplined expansion – Operators are carefully managing spectrum and capacity to protect mobile performance, limiting how aggressively Fixed Wireless Access can scale. Bundling and competition – Lower-cost bundles remain attractive to consumers, but cable competition and churn between FWA providers could temper subscriber gains. This week, Dell’Oro Group released a report finding that Fixed Wireless Access (FWA) continues to gain momentum, with total FWA revenues — including RAN equipment, residential CPE, and enterprise routers and gateways — on track to…

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. Meet the man hunting the spies in your smartphone In April 2025, Ronald Deibert left all electronic devices at home in Toronto and boarded a plane. When he landed in Illinois, he bought a new laptop and iPhone. He wanted to reduce the risk of having his personal devices confiscated, because he knew his work made him a prime target for surveillance. “I’m traveling under the assumption that I am being watched, right down to exactly where I…

Container nodes in Cisco Modeling Labs (CML) 2.9 complement virtual machines, offering greater flexibility and efficiency. Engineers benefit from having lightweight, programmable, and rapidly deployable options within their simulation environments. While virtual machines (VMs) dominate with network operating systems, containers add flexibility, enabling tools, traffic injectors, automation, and full applications to run smoothly with your CML topology. Traditional virtual machines are still effective, but custom containers introduce a transformative agility. Building images that behave predictably and integrate cleanly with simulated networks is much easier with containers. As anyone who has tried to drop a stock Docker image into CML quickly…

Posted by Eric Lynch, Senior Product Manager, Android Security, and Sherif Hanna, Group Product Manager, Google C2PA Core At Made by Google 2025, we announced that the new Google Pixel 10 phones will support C2PA Content Credentials in Pixel Camera and Google Photos. This announcement represents a series of steps towards greater digital media transparency: The Pixel 10 lineup is the first to have Content Credentials built in across every photo created by Pixel Camera. The Pixel Camera app achieved Assurance Level 2, the highest security rating currently defined by the C2PA Conformance Program. Assurance Level 2 for a mobile…

Support CleanTechnica’s work through a Substack subscription or on Stripe. Eavor is a next-generation geothermal energy company that set out to solve one of the long-standing limits of geothermal power. Conventional geothermal electrical generation only works where naturally permeable, water bearing hot rock exists close enough to the surface. Eavor’s idea was different. Instead of relying on naturally flowing hot fluids, it proposed drilling deep, sealed loops of pipe through hot rock, circulating a working fluid through them, extracting heat by conduction, and bringing that heat to the surface for electricity generation or industrial and district heat. In late 2025,…

9/25/18 2:20 PM · 1 min read The facade design pattern is a simplified interface over a complex subsystem. Let me show you a real quick example using Swift. What is a facade?The name of the facade pattern comes from real life building architecture.one exterior side of a building, usually the frontIn software development this definition can be translated to something like everything that’s outside, hiding all the internal parts. So the main purpose of a facade is to provide a beautiful API over some more complex ugly ones. 😅Usually the facade design pattern comes handy if you have two or…
