Atomic-level surface control boosts brightness of eco-friendly nanosemiconductors by 18-fold

Light-emitting semiconductors are used throughout everyday life in TVs, smartphones, and lighting. However, many technical barriers remain in developing environmentally friendly semiconductor materials.

In particular, nanoscale semiconductors that are tens of thousands of times smaller than the width of a human hair (about 100,000 nanometers) are theoretically capable of emitting bright light, yet in practice have suffered from extremely weak emission. KAIST researchers have now developed a new surface-control technology that overcomes this limitation.

A KAIST research team led by Professor Himchan Cho of the Department of Materials Science and Engineering has developed a fundamental technology to control, at the atomic level, the surface of indium phosphide (InP) magic-sized clusters (MSCs)—nanoscale semiconductor particles regarded as next-generation eco-friendly semiconductor materials.

Sony AI patent will see PlayStation games play themselves when players are stuck

The AI-generated Ghost Player system appears to be an evolution of the PS5 Game Help system, which was launched alongside the PlayStation [11,413 articles] href=https://www.videogameschronicle.com/platforms/playstation/ PlayStation fans who enjoy hunting trophies, due to the convenience of not having to call up a separate guide on another screen, such as a phone.

It is worth noting that there is no evidence that Sony has plans to use this technology in future hardware, and that patents like this have been filed by the firm, and many others, for years without any intention for use.

Google plans to make Chrome for Android an agentic browser with Gemini

Google appears to be testing a new feature that integrates Gemini into Chrome for Android, allowing you to use agentic browser capabilities on your mobile device.

As spotted by Leo on X, Google is testing agentic capabilities and Gemini integration for Chrome on Android.

This claim is based on new references spotted on Chromium, which is the source code of Chrome.

An earthquake on a chip: New tech could make smartphones smaller, faster

A team of engineers has made major strides in generating the tiniest earthquakes imaginable. The team’s device, known as a surface acoustic wave phonon laser, could one day help scientists make more sophisticated versions of chips in cellphones and other wireless devices—potentially making those tools smaller, faster and more efficient.

The study was conducted by Matt Eichenfield, an incoming faculty member at the University of Colorado Boulder, and scientists from the University of Arizona and Sandia National Laboratories. The researchers published their findings in the journal Nature.

The new technology utilizes a phenomenon known as surface acoustic waves, or SAWs act a little like soundwaves, but, as their name suggests, they travel only on the top layer of a material.

New global standard set for testing graphene’s single-atom thickness

Graphene could transform everything from electric cars to smartphones, but only if we can guarantee its quality. The University of Manchester has led the world’s largest study to set a new global benchmark for testing graphene’s single-atom thickness. Working with the UK’s National Physical Laboratory (NPL) and 15 leading research institutes worldwide, the team has developed a reliable method using transmission electron microscopy (TEM) that will underpin future industrial standards.

Researchers at the University of Manchester, working with the UK’s National Physical Laboratory and 15 international partners, have developed a robust protocol using transmission electron microscopy (TEM). The results, published in 2D Materials, will underpin a new ISO technical specification for graphene.

“To incorporate graphene and other 2D materials into industrial applications, from light-weight vehicles to sports equipment, touch screens, sensors and electronics, you need to know you’re working with the right material. This study sets a global benchmark that industry can trust,” said Dr. William Thornley, who worked on the research during his Ph.D.

A dry surface thanks to fluid physics: Contact-free method gently remove liquids from delicate microstructures

Researchers at the University of Konstanz have developed a gentle, contact-free method to collect liquids and remove them from microscopic surface structures. The method uses vapor condensation to generate surface currents that transport droplets off surfaces.

Many modern technologies rely on microscopic elements, such as microchips in smartphones. The manufacturing process for these elements requires their surfaces to be exposed to different types of liquids that must be completely removed afterward.

A research team led by Stefan Karpitschka from the University of Konstanz has now developed a new method that uses surface tension to efficiently transport these liquids off the finished product. The work is published in the journal Proceedings of the National Academy of Sciences.

First Therapy Chatbot Trial Yields Mental Health Benefits

Dartmouth researchers conducted the first-ever clinical trial of a generative AI-powered therapy chatbot and found that the software resulted in significant improvements in participants’ symptoms, according to results published March 27 in NEJM AI.

People in the study also reported they could trust and communicate with the system, known as Therabot, to a degree that is comparable to working with a mental health professional.

The trial consisted of 106 people from across the United States diagnosed with major depressive disorder, generalized anxiety disorder, or an eating disorder. Participants interacted with Therabot through a smartphone app by typing out responses to prompts about how they were feeling or initiating conversations when they needed to talk.

OLED lighting: Corrugated panel design extends longevity and efficiency

The organic light emitting diodes—known widely as OLEDs—that create vibrant smartphone displays could illuminate rooms, but current designs burn out too quickly at the high brightness needed for room lighting. A new approach overcomes this tradeoff by building OLEDs on a corrugated surface, packing more emitting material into a given lighting panel area to produce the same amount of light while operating the OLED itself at lower brightness.

This corrugated panel strategy increased device lifespan by a factor of 2.7 compared to flat panels operated at the same current, according to a study led by the University of Michigan in collaboration with OLEDWorks and The Pennsylvania State University.

“While the problems we solved along the way were daunting, in the end the new device performed tremendously better than predecessors. It’s rewarding to see our ideas point towards a valid path to improve the efficiency and lifetime of OLED lighting,” said Max Shtein, a professor of materials science and engineering and chemical engineering at U-M and co-corresponding author of the study published in Nature Communications.
