DragonFire laser weapon achieves UK’s first high-power firing

Posted by in categories: energy, military

The DragonFire laser-directed energy weapon (LDEW) system has achieved the UK’s first high-power firing of a laser weapon against aerial targets during a trial at the MOD’s Hebrides Range.

The DragonFire is a line-of-sight weapon and can engage with any visible target, and its range is classified. The system is able to deliver a high-power laser over long ranges and requires precision equivalent to hitting a £1 coin from a kilometer away.

Laser-directed energy weapons are incredibly powerful and can engage targets at lightning-fast speeds. They use a concentrated beam of light to cut through their target, resulting in structural failure or other devastating outcomes if the warhead is targeted.

Advanced full-color image sensor technology enables simultaneous energy harvesting and imaging

Posted by in categories: energy, nanotechnology

Organic-based optoelectronic technology is increasingly recognized as an energy-efficient solution for low-power indoor electronics and wireless IoT sensors. This is largely due to its superior flexibility and light weight compared to conventional silicon-based devices. Notably, organic photovoltaic cells (OPVs) and organic photodetectors (OPDs) are leading examples in this field.

OPVs have the remarkable ability to absorb energy and generate electricity even under very low light conditions, while OPDs are capable of capturing images. However, despite their potential, the development of these devices has thus far been conducted independently. As a result, they have not yet reached the level of efficiency necessary to be considered practical for next-generation, miniaturized devices.

A Korea Institute of Science and Technology (KIST) research team, led by Dr. Min-Chul Park and Dr. Do Kyung Hwang of the Center for Opto-Electronic Materials and Devices, Prof. Jae Won Shim and Prof. Tae Geun Kim of the School of Electrical Engineering at Korea University, Prof. JaeHong Park of the Department of Chemistry and Nanoscience at Ewha Womans University, have now developed an organic-based optoelectronic device.

Engineers at UMass Amherst Harvest Abundant Clean Energy from Thin Air, 24/7

Posted by in categories: energy, materials

A team of engineers at the University of Massachusetts Amherst has recently shown that nearly any material can be turned into a device that continuously harvests electricity from humidity in the air.


Researchers describe the “generic Air-gen effect”—nearly any material can be engineered with nanopores to harvest, cost effective, scalable, interruption-free electricity.

VexTrio: The Uber of Cybercrime — Brokering Malware for 60+ Affiliates

Posted by in categories: cybercrime/malcode, energy, information science

VexTrio, the shadowy entity controlling a massive network of 70,000+ domains, is finally in the spotlight. This “traffic broker” fuels countless scams & malware campaigns, including ClearFake, SocGholish, & more. Read:


The threat actors behind ClearFake, SocGholish, and dozens of other actors have established partnerships with another entity known as VexTrio as part of a massive “criminal affiliate program,” new findings from Infoblox reveal.

The latest development demonstrates the “breadth of their activities and depth of their connections within the cybercrime industry,” the company said, describing VexTrio as the “single largest malicious traffic broker described in security literature.”

The Green Spark: A Catalyst Transforming Water Into Energy Wealth

Posted by in categories: energy, sustainability

A stable, reactive, and cost-effective ruthenium catalyst for sustainable hydrogen production through proton exchange membrane water electrolysis.

Sustainable electrolysis for green hydrogen production is challenging, primarily due to the absence of efficient, low-cost, and stable catalysts for the oxygen evolution reaction in acidic solutions. A team of researchers has now developed a ruthenium catalyst by doping it with zinc, resulting in enhanced stability and reactivity compared to its commercial version. The proposed strategy can revolutionize hydrogen production by paving the way for next generation electrocatalysts that contribute to clean energy technologies.

Electrolysis and Catalyst Challenges.
