Science'Electron Waiting Room' Lets Blue Titanium Dioxide Hold Sunlight's Energy 2.5 Times Longer
KAIST-led researchers used an X-ray laser to watch oxygen vacancies trap electrons, a clue for better sunlight-driven hydrogen production.
PhysicsChina's FAST Telescope Finds a Starless Hydrogen Cloud That May Be a True 'Dark Galaxy'
The isolated cloud J1351+0039 holds about 130 million suns of mass and shows no stars in deep optical images.
ScienceNickel's Active Surface Isn't What Chemists Assumed for Decades, Ulm Team Finds
Watching nickel electrodes while they split water, researchers found the working layer is nickel dioxide, not nickel oxyhydroxide, forcing a rethink of hydrogen catalyst chemistry.
ScienceOregon State Chemists Make Hydrogen From Water With a Sulfur-Based Light Catalyst
The new material, BVR-19, needs no added expensive metal catalyst and forms in water at room temperature, which could help cut the cost of green hydrogen.
ScienceWhy Do Pickles Glow Orange When Plugged In? A Portland State Engineer Has an Answer
After burning more than 100 pickles, Josh Méndez says the classroom stunt is a hybrid: an electrical spark ignites hydrogen gas, and sodium in the brine supplies the color.
PhysicsCanada's CHIME Telescope Catches the Faint Glow of Hydrogen From 5 Billion Years Ago
For the first time the radio telescope detected the cosmic hydrogen signal using only its own data. That opens a cheaper, faster route to testing what dark energy really is.
PhysicsChina's FAST Telescope Found Two Hydrogen Clouds Near M51 With No Stars in Them at All
Each holds about three million suns' worth of hydrogen inside a halo weighing 3.7 billion solar masses. If the interpretation holds, they are dark matter halos that never lit up.
ScienceThe Same Silver Particle Runs the Reaction in Two Different Places Depending on Which Way the Cell Is Running
A Seoul National University team found the active site on a solid oxide cell's silver nanocatalyst moves when the device flips from making electricity to making hydrogen.
ScienceA Hollow Carbon Sphere With Channels Like Spokes Let a Fuel Cell Survive 150,000 Voltage Cycles on a Sliver of Platinum
Washington University engineers cracked a trade-off that has blocked fuel-cell catalysts for years, and they are aiming it at the data centers now on track to eat 9% of U.S. electricity.
PhysicsA German Turbine Ran 303 Seconds on Hydrogen Detonations and Made Electricity With No Compressor at All
Conventional gas turbines burn about half their own output driving an air compressor. Karlsruhe engineers deleted the compressor and used detonation waves to raise the pressure instead — beating NASA's runtime record by 53 seconds.
ScienceHydrogen May Be Flowing Through the Solid Iron of Earth’s Inner Core Like a Liquid Through a Sponge
Quantum simulations published in PNAS find hydrogen concentrated at about 16% at the inner core boundary, thinning to 9% at the center — and moving through the iron lattice while the iron itself stays solid.
ScienceNew Catalyst Turns Factory Waste Heat Into Hydrogen at a Fraction of the Usual Temperature
University of Birmingham researchers say their abundant, non-toxic perovskite splits water into hydrogen at 150 to 500 degrees Celsius — potentially undercutting both green and blue hydrogen on cost.
ScienceA Platinum-Free Catalyst Runs 1,000 Hours, Pointing to Cheaper Clean Hydrogen
Washington University engineers built a metal-phosphide cathode that outperformed platinum-based versions in lab tests, tackling one of the biggest cost barriers to green hydrogen.
ScienceNew Catalyst Splits Water Into Hydrogen at Far Lower Temperatures, Turning Waste Heat Into Clean Fuel
University of Birmingham researchers say their perovskite catalyst, built from cheap and non-toxic metals, could make hydrogen for less than today's 'green' and 'blue' methods by harnessing heat factories already throw away.
PhysicsAncient Chemistry Unlocks Revolutionary Glass That Traps CO2 and Hydrogen
Researchers adapt centuries-old glassmaking techniques to create advanced materials for clean energy and gas storage applications.
PhysicsProton Measured with Record Precision, Confirming Standard Model to One Trillionth of a Percent
Max Planck Institute physicists used hydrogen spectroscopy to measure the proton's charge radius to 2.5 times greater precision than before, resolving the proton radius puzzle and setting the most demanding test of quantum electrodynamics ever conducted.
