Professor Yongzhe Wun's team at East China University of Science and Technology significantly improved the interfacial contact and mechanical stability of inverted perovskite solar cells by constructing triphenylamine-based co-assembled hole transport monolayers. This work addressed key issues such as poor interfacial wettability and insufficient mechanical stability of traditional carbazole-based self-assembled monolayers (e.g., Me-4PACz) in inverted perovskite solar cells. They designed and synthesized a series of multi-legged triphenylamine derivatives (TPA-nCPA) containing cyanoethylphosphonic acid anchoring groups and innovatively proposed a co-assembly strategy with Me-4PACz. Rigid devices fabricated based on this strategy achieved an excellent photoelectric conversion efficiency of 26.27%, while flexible devices achieved an efficiency of 22.38%. Furthermore, after 5000 cycles at a 5mm bending radius, they maintained 90% of their initial efficiency, demonstrating outstanding mechanical stability. The article was published as an open access research article in CCS Chemistry, the flagship journal of the Chinese Chemical Society.

A new study highlights a promising path toward sustainable hydrogen peroxide production using sunlight, oxygen, and water, offering a cleaner alternative to the energy-intensive anthraquinone process that dominates global manufacturing today.

Since most people carry their phones with them every day, Shogo Takada is working on a way to use smartphone microphones to assist in locating disaster victims. The method combines two types of sound sources, monopole and dipole. In a disaster situation, a rescuer would emit two dipole sounds, which would be received by the microphone of a trapped victim, and then an electromagnetic wave would be sent from the victim’s phone to broadcast their location.

An international team of astronomers led by Oskar Klein Centre (OKC) researcher Joel Johansson has discovered SN 2025wny, the first spatially resolved, gravitationally lensed superluminous supernova ever observed. The discovery provides a striking confirmation of Einstein’s theory of General Relativity and a rare window into a powerful stellar explosion from the early Universe.

For his forward-leaning research into quantum sensing, U.S. Navy Cmdr. Jens Berdahl, a former naval aviator and F/A-18 pilot pursuing his doctorate at the Naval Postgraduate School (NPS) through the service’s Permanent Military Professor (PMP) program, was presented with the highly competitive Margaret Burbidge Award for Best Experimental Research by a Graduate Student by the American Physical Society, Far West Section. 

Why does plastic turn brittle and paint fade when exposed to the sun for long periods? Scientists have long known that such organic photodegradation occurs due to the sun’s energy generating free radicals: molecules that have lost an electron to sunlight-induced ionization and have been left with an unpaired one, making them very eager to react with other molecules in the environment. However, the exact mechanisms for how and why the energy from the sun’s photons get stored and released in the materials over very long periods have eluded empirical evidence.  

The problem lies in the timeframe. While scientists have access to extremely sophisticated spectroscopy equipment capable of measuring the energy levels of individual electrons at femtosecond to millisecond scales in organic materials, they have paid little attention to time scales beyond seconds – and these are processes that can take years.  

As such, slow, transient charge accumulation has presented a disappointing data gap in both applied and theoretical optics. But now, researchers from the Organic Optoelectronics Unit at the Okinawa Institute of Science and Technology (OIST) have addressed this challenge with a new methodology that detects these faint signals. Their findings are published in Science Advances.

Browaeys is recognized for the development of arrays of single neutral atoms held in optical tweezers as a platform for exquisitely controlled quantum simulation of many-body physics.

A team from the Faculty of Physics and the Centre for Quantum Optical Technologies at the Centre of New Technologies, University of Warsaw has developed a new method for measuring elusive terahertz signals using a "quantum antenna." The authors of the work utilized a novel setup for radio wave detection with Rydberg atoms to not only detect but also precisely calibrate a so-called frequency comb in the terahertz band. This band was until recently a white spot in the electromagnetic spectrum, and the solution described in the prestigious journal Optica paves the way for ultrasensitive spectroscopy and a new generation of quantum sensors operating at room temperature.

Iron-on patches can repair clothing or add personal flair to backpacks and hats. And now they could power wearable tech, too. Researchers reporting in ACS Applied Materials & Interfaces have combined liquid metal and a heat-activated adhesive to create an electrically conductive patch that bonds to fabric when heated with a hot iron. In demonstrations, circuits ironed onto a square of fabric lit up LEDs and attached an iron-on microphone to a button-up shirt.
