Researchers 'unzip' 2D materials with lasers      (via sciencedaily.com)     Original source 

Researchers used commercially available tabletop lasers to create tiny, atomically sharp nanostructures in samples of a layered 2D material called hexagonal Boron Nitride (hBN). The new nanopatterning technique is a simple way to modify materials with light--and it doesn't involve an expensive and resource-intensive clean room.

The Clues for Cleaner Water      (via sciencedaily.com)     Original source 

By using experimental electrochemical analyses, mass spectrometry, and computational quantum chemistry modeling, the researchers created an 'atomic-scale storyline' to explain how ozone is generated on NATO electrocatalysts. They identified that some of the nickel in NATO is probably leaching out of the electrodes via corrosion, and these nickel atoms, now floating in the solution near the catalyst, can promote chemical reactions that eventually generate ozone.

When injecting pure spin into chiral materials, direction matters      (via sciencedaily.com)     Original source 

The direction in which spin information is injected into chiral materials affects its ability to pass through them. These chiral 'gateways' could be used to design energy-efficient spintronic devices for data storage, communication and computing.

Physicists arrange atoms in extremely close proximity      (via sciencedaily.com)     Original source 

Physicists developed a technique to arrange atoms in much closer proximity than previously possible, down to 50 nanometers. The group plans to use the method to manipulate atoms into configurations that could generate the first purely magnetic quantum gate -- a key building block for a new type of quantum computer.

New sensor detects errors in MRI scans      (via sciencedaily.com)     Original source 

A new prototype sensor is capable of detecting errors in MRI scans using laser light and gas. The new sensor can thereby do what is impossible for current electrical sensors -- and hopefully pave the way for MRI scans that are better, cheaper and faster.

To bend the curve of biodiversity loss, nature recovery must be integrated across all sectors      (via sciencedaily.com)     Original source 

The alarming rates of biodiversity loss worldwide have made clear that the classical way of governing biodiversity recovery based on protected areas and programs for the protection of endangered species is not enough. To tackle this, almost 200 countries committed to the active 'mainstreaming' or integration of biodiversity targets into policies and plans across relevant sectors. However, research suggests that this has until now been largely ineffective due to non-binding commitments, vaguely formulated targets, 'add-on' biodiversity initiatives, and too few resources. 'Top down regulation is also needed,' say the authors.

Big data reveals true climate impact of worldwide air travel      (via sciencedaily.com)     Original source 

A new study that looked at nearly 40 million flights in 2019 calculated the greenhouse gas emissions from air travel for essentially every country on the planet. At 911 million tons, the total emissions from aviation are 50 per cent higher than the 604 million tons reported to the United Nations for that year.

How can forests be reforested in a climate-friendly way?      (via sciencedaily.com)     Original source 

Europe's forests have already been severely affected by climate change. Thousands of hectares of trees have already died due to drought and bark beetles. Scientists have now investigated which trees can be used for reforestation. Their findings: only a few tree species are fit for the future, such as English oak in the UK. However, mixed forests are important for the survival of forests, otherwise the forest ecosystem as a whole could be weakened.

Atomic nucleus excited with laser: a breakthrough after decades      (via sciencedaily.com)     Original source 

For the first time, the state of an atomic nucleus was switched with a laser. For decades, physicists have been looking for such a nuclear transition -- now it has been found. This opens up a new field of research with many technological applications. Now, nuclei can be used for extremely precise measurements. For example, a nuclear clock could be built that could measure time more precisely than the best atomic clocks available today.
