Researchers have created a high-power tunable laser on silicon photonics, achieving nearly 2 watts using an LMA amplifier. This advancement could revolutionize integrated photonics, with potential applications in space exploration, reducing satellite costs while enhancing capabilities.

In today’s world, the size of various systems continues to decrease, incorporating increasingly smaller components for applications like high-speed data centers and space exploration with compact satellites.

However, this trend toward miniaturization and high-density integration—driven by advancements in integrated photonics—has significantly compromised the ability of these systems to generate high signal power. Traditionally, high-power output has been associated with larger systems, such as fiber and solid-state platforms, whose substantial physical dimensions allow for greater energy storage.

A breakthrough in decoding the growth process of hexagonal boron nitride (hBN), a 2D material, and its nanostructures on metal substrates could pave the way for more efficient electronics, cleaner energy solutions and greener chemical manufacturing, according to new research from the University of Surrey published in the journal Small.

Only one atom thick, hBN—often nicknamed “white graphene”—is an ultra-thin, super-resilient material that blocks electrical currents, withstands extreme temperatures and resists chemical damage. Its unique versatility makes it an invaluable component in , where it can protect delicate microchips and enable the development of faster, more efficient transistors.

Going a step further, researchers have also demonstrated the formation of nanoporous hBN, a novel material with structured voids that allows for selective absorption, advanced catalysis and enhanced functionality, vastly expanding its potential environmental applications. This includes sensing and filtering pollutants—as well as enhancing advanced energy systems, including hydrogen storage and electrochemical catalysts for fuel cells.

In an unprecedented new study, researchers have shown neurotransmitters in the human brain are released during the processing of the emotional content of language, providing new insights into how people interpret the significance of words.

The work, conducted by an international team led by Virginia Tech scientists, offers deeper understanding into how language influences human choices and mental health.

Spearheaded by computational neuroscientist Read Montague, a professor of the Fralin Biomedical Research Institute at VTC and director of the institute’s Center for Human Neuroscience Research, the study represents a first-of-its-kind exploration of how neurotransmitters process the emotional content of language—a uniquely human function.

Ferroelectrics are special materials with polarized positive and negative charges—like a magnet has north and south poles—that can be reversed when external electricity is applied. The materials will remain in these reversed states until more power is applied, making them useful for data storage and wireless communication applications.

Now, turning a non-ferroelectric material into one may be possible simply by stacking it with another ferroelectric material, according to a team led by scientists from Penn State who demonstrated the phenomenon, called proximity ferroelectricity.

The discovery offers a new way to make without modifying their chemical formulation, which commonly degrades several useful properties. This has implications for next-generation processors, optoelectronics and quantum computing, the scientists said. The researchers published their findings in the journal Nature.

Glass might seem to be an ordinary material we encounter every day, but the physics at play inside are actually quite complex and still not completely understood by scientists. Some panes of glass, such as the stained-glass windows in many medieval buildings, have remained rigid for centuries, as their constituent molecules are perpetually frozen in a state of disorder.

Similarly, supercooled liquids are not quite solid, in the sense that their fundamental particles do not stick to a lattice pattern with , but they are also not ordinary liquids, because the particles also lack the energy to move freely. More research is required to reveal the physics of these complex systems.

In a study published in Nature Materials, researchers from the Institute of Industrial Science, the University of Tokyo have used advanced computer simulations to model the behavior of in a glassy supercooled liquid. Their approach was based on the concept of the Arrhenius activation energy, which is the a process must overcome to proceed.
