Unlike conventional silicon-based solar cells, perovskite solar cells (PSCs) are not only thin and lightweight, but can also be seamlessly applied to curved surfaces, like building facades and vehicle roofs. What’s more, they can be easily manufactured at room temperature using a solution process, leading to significantly reduced production costs.

However, for PSCs to achieve commercialization, it is crucial to develop technologies that maintain high efficiency over extended periods. A research team affiliated with UNIST has successfully made strides in this area. Their work is published in the journal Joule.

Professor Sang Il Seok of the School of Energy and Chemical Engineering at UNIST, along with researchers Jongbeom Kim and Jaewang Park, has developed an interlayer that leverages the specificity of organic cations on the surface of PSCs, simultaneously achieving and durability.

Phishing platform ‘Lucid’ behind wave of iOS, Android SMS attacks https://lifeboat.com/blog/2025/04/phishing-platform-lucid-behind-wave-of-ios-android-sms-attacks https://lifeboat.com/blog/2025/04/phishing-platform-lucid-behind-wave-of-ios-android-sms-attacks#respond Tue, 01 Apr 2025 11:23:46 +0000 https://lifeboat.com/blog/2025/04/phishing-platform-lucid-behind-wave-of-ios-android-sms-attacks

A phishing-as-a-service (PhaaS) platform named ‘Lucid’ has been targeting 169 entities in 88 countries using well-crafted messages sent on iMessage (iOS) and RCS (Android).

Lucid, which has been operated by Chinese cybercriminals known as the ‘XinXin group’ since mid-2023, is sold to other threat actors via a subscription-based model that gives them access to over 1,000 phishing domains, tailored auto-generated phishing sites, and pro-grade spamming tools.

Prodaft researchers note that XinXin has also been using the Darcula v3 platform for its operations, which indicates a potential connection between the two PhaaS platforms.

Taking the ‘forever’ out of ‘forever chemicals’: Scientists work out how to destroy the PFAS in batteries https://lifeboat.com/blog/2025/03/taking-the-forever-out-of-forever-chemicals-scientists-work-out-how-to-destroy-the-pfas-in-batteries https://lifeboat.com/blog/2025/03/taking-the-forever-out-of-forever-chemicals-scientists-work-out-how-to-destroy-the-pfas-in-batteries#respond Mon, 31 Mar 2025 19:04:59 +0000 https://lifeboat.com/blog/2025/03/taking-the-forever-out-of-forever-chemicals-scientists-work-out-how-to-destroy-the-pfas-in-batteries

Lithium-ion batteries are part of everyday life. They power small rechargeable devices such as mobile phones and laptops. They enable electric vehicles. And larger versions store excess renewable energy for later use, supporting the clean energy transition.

Australia produces more than 3,000 metric tons of lithium-ion battery a year. Managing this waste is a technical, economic and social challenge. Opportunities exist for and creating a circular economy for batteries. But they come with risk.

That’s because contain manufactured chemicals such as PFAS, or per-and polyfluoroalkyl substances. The chemicals carry the lithium—along with electricity—through the battery. If released into the environment, they can linger for decades and likely longer. This is why they’ve been dubbed “forever chemicals

21 Most Cited Control Theory Papers https://lifeboat.com/blog/2025/03/21-most-cited-control-theory-papers https://lifeboat.com/blog/2025/03/21-most-cited-control-theory-papers#respond Sat, 29 Mar 2025 18:12:17 +0000 https://lifeboat.com/blog/2025/03/21-most-cited-control-theory-papers

What is Control? here is a nice definition according to Wikipedia — Control engineering or control systems engineering is an engineering discipline that deals with control systems, applying control theory to design equipment and systems with desired behaviors in control environments. The discipline of controls overlaps and is usually taught along with electrical engineering and mechanical engineering at many institutions around the world. The practice uses sensors and detectors to measure the output performance of the process being controlled; these measurements are used to provide corrective feedback helping to achieve the desired performance. Systems designed to perform without requiring human input are called automatic control systems (such as cruise control for regulating the speed of a car).

Dirac’s Plate Trick, the Hairy Ball Theorem and more: Research probes physics of irregular objects on inclined planes https://lifeboat.com/blog/2025/03/diracs-plate-trick-the-hairy-ball-theorem-and-more-research-probes-physics-of-irregular-objects-on-inclined-planes https://lifeboat.com/blog/2025/03/diracs-plate-trick-the-hairy-ball-theorem-and-more-research-probes-physics-of-irregular-objects-on-inclined-planes#respond Fri, 28 Mar 2025 06:19:09 +0000 https://lifeboat.com/blog/2025/03/diracs-plate-trick-the-hairy-ball-theorem-and-more-research-probes-physics-of-irregular-objects-on-inclined-planes

How gravity causes a perfectly spherical ball to roll down an inclined plane is part of the elementary school physics canon. But the world is messier than a textbook.

Scientists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have sought to quantitatively describe the much more complex rolling physics of real-world objects. Led by L. Mahadevan, the Lola England de Valpine Professor of Applied Mathematics, Physics, and Organismic and Evolutionary Biology in SEAS and FAS, they combined theory, simulations, and experiments to understand what happens when an imperfect, spherical object is placed on an inclined plane.

Published in Proceedings of the National Academy of Sciences, the research, which was inspired by nothing more than curiosity about the everyday world, could provide fundamental insights into anything that involves irregular objects that roll, from nanoscale cellular transport to robotics.
