A further development in atomic force microscopy now makes it possible to simultaneously image the height profile of nanometer-fine structures as well as the electric current and the frictional force at solid-liquid interfaces. A team has succeeded in analyzing electrocatalytically active materials and gaining insights that will help optimize catalysts. The method is also potentially suitable for studying processes on battery electrodes, in photocatalysis or on active biomaterials.

One month after announcing a ferroelectric semiconductor at the nanoscale thinness required for modern computing components, a team has now demonstrated a reconfigurable transistor using that material. Their work paves the way for single amplifiers that can do the work of multiple conventional amplifiers, among other possibilities.

Researchers have developed a new 'camera' that sees the local disorder in materials. Its key feature is a variable shutter speed: because the disordered atomic clusters are moving, when the team used a slow shutter, the dynamic disorder blurred out, but when they used a fast shutter, they could see it. The method uses neutrons to measure atomic positions with a shutter speed of around one picosecond, a trillion times faster than normal camera shutters.

Development of all-solid-state batteries is crucial to achieve carbon neutrality. However, their high surface resistance causes these batteries to have low output, limiting their applications. To this end, researchers have employed a novel technique to investigate and modulate electric double layer dynamics at the solid/solid electrolyte interface. The researchers demonstrate unprecedented control of response speed by over two orders of magnitude, a major steppingstone towards realization of commercial all-solid-state batteries.

Lithium-ion batteries dominate among energy storage devices and are the battery of choice for the electric vehicle industry. Improving battery performance is a constant impetus to current research in this field. Towards this end, a group of researchers has synthesized a lithium borate-type aqueous polyelectrolyte binder for graphite anodes. Their new binder helped improve Li-ion diffusion and lower impedance compared to conventional batteries.

Astrophysicists have discovered the tightest ultracool dwarf binary system ever observed. The two stars are so close that it takes them less than one Earth day to revolve around each other. In other words, each star's 'year' lasts just 17 hours.

Scientists identified about 140,000 molecular clouds in the Milky Way Galaxy from large-scale data of carbon monoxide molecules, observed in detail by the Nobeyama 45-m radio telescope. Using artificial intelligence, the researchers estimated the distance of each of these molecular clouds to determine their size and mass, successfully mapping the distribution of the molecular clouds in the Galaxy in the most detailed manner to date.

While analyzing data from the first images of a well-known early galaxy taken by NASA's James Webb Space Telescope (JWST), astronomers discovered a companion galaxy previously hidden behind the light of the foreground galaxy -- one that surprisingly seems to have already hosted multiple generations of stars despite its young age, estimated at 1.4 billion years old.

Researchers have discovered that channeling ions into defined pathways in perovskite materials improves the stability and operational performance of perovskite solar cells. The finding paves the way for a new generation of lighter, more flexible, and more efficient solar cell technologies suitable for practical use.

Perovskites, a family of materials with unique electric properties, show promise for use in a variety fields, including next-generation solar cells. A team of scientists has now created a new process to fabricate large perovskite devices that is more cost- and time-effective than previously possible and that they said may accelerate future materials discovery.

An object near the supermassive black hole at the center of the Milky Way galaxy has drawn the interest of scientists because it has evolved dramatically in a relatively short time. A new study suggests that the object, called X7, could be a cloud of dust and gas that was created when two stars collided. The researchers believe it will eventually be drawn toward the black hole and will disintegrate.

Astronomers have discovered a rapidly growing black hole in one of the most extreme galaxies known in the very early Universe. The discovery of the galaxy and the black hole at its center provides new clues on the formation of the very first supermassive black holes.
