Green hydrogen: "Rust" as a photoanode and its limits
Hydrogen will be needed in large quantities as an energy carrier and raw material in the energy system of the future. To achieve this, however, hydrogen must be produced in a climate-neutral way, for example through so-called photoelectrolysis, by us.....»»
The energy transition requires a lot of minerals and metals—which could impact our lakes
Bringing about the energy transition is essential, but it will require developing a significant amount of minerals and "green" electricity, such as hydroelectricity. These activities often take place on Indigenous lands and will have environmental co.....»»
3D covalent organic frameworks with zyg topology for photocatalytic synthesis of hydrogen peroxide
A research team proposed a new synthetic strategy of COFs based on a new topology that remotely separates donor (D) and acceptor (A) units in 3D lattice to produce the expected metastable photo-induced charge-separated states......»»
Compact cities found to have lower carbon emissions but poorer air quality, less green space and higher mortality rates
What types of cities exist in Europe and which are more favorable in terms of human health, environmental quality and carbon footprint? To answer these questions, a study led by the Barcelona Institute for Global Health (ISGlobal) has analyzed 919 Eu.....»»
Scientists achieve first intercity quantum key distribution with deterministic single-photon source
Conventional encryption methods rely on complex mathematical algorithms and the limits of current computing power. However, with the rise of quantum computers, these methods are becoming increasingly vulnerable, necessitating quantum key distribution.....»»
The universe"s biggest explosions made elements we are composed of, but there"s another mystery source out there
After its "birth" in the Big Bang, the universe consisted mainly of hydrogen and a few helium atoms. These are the lightest elements in the periodic table. More-or-less all elements heavier than helium were produced in the 13.8 billion years between.....»»
The Delhi heat wave is testing the limits of human endurance: Other hot countries should beware and prepare
Delhi is reeling from the most extreme heat wave India has ever seen. While the record-breaking maximum recorded temperature of 52.9°C has been called into question by India's Meteorological Department, it's entirely possible. The city has been swel.....»»

Health risks from global warming can help drive city climate action, study finds
Cities around the world were more likely to maintain climate action and enact "green recovery" long-term plans after the pandemic if local decision-makers were more alert to the health risks of climate change, a new global study has shown......»»
Producing gold nano-particles (and hydrogen) in water without the need for toxic chemicals
In a surprise discovery, Flinders University nanotechnology researchers have produced a range of different types of gold nanoparticles by adjusting water flow in the novel vortex fluidic device—without the need for toxic chemicals. The article, "Na.....»»
Apple versus donut: How the shape of a tokamak impacts the limits of the edge of the plasma
Harnessing energy from plasma requires a precise understanding of its behavior during fusion to keep it hot, dense and stable. A new theoretical model about a plasma's edge, which can become unstable and bulge, brings the prospect of commercial fusio.....»»
