Machine Learning Helps to Locally Restore Wetlands
Worldwide, coastal wetlands like salt marshes and mangroves are increasingly recognized as valuable natural defenses that protect coasts. Tidal salt marshes enhance flood safety by being 'wave absorbers' that protect the dikes behind them, and by being 'flood fighters' that lower the flood depth by limiting the size of breaches when a dike would fail during severe storms. This raises the question if we can establish and restore these wetlands where needed, now that the sea level is rising, and storms become stronger and more frequent.

Transparent Nanolayers for More Solar Power
Silicon solar cells have been steadily improved over the past decades and have already reached a very high level of development. However, the disturbing effect of recombination still occurs after the absorption of sunlight and the photovoltaic generation of electrical charge carriers. In this process, negative and positive charge carriers that have already been generated combine and cancel each other out before they could be used for the flow of solar electricity. This effect can be countered by special materials that have a special property - passivation.

Engineers Mix and Match Materials to Make New Stretchy Electronics
At the heart of any electronic device is a cold, hard computer chip, covered in a miniature city of transistors and other semiconducting elements. Because computer chips are rigid, the electronic devices that they power, such as our smartphones, laptops, watches, and televisions, are similarly inflexible. Now a process developed by engineers may be the key to manufacturing flexible electronics with multiple functionalities in a cost-effective way.

Route to flexible electronics made from exotic materials
Engineers have developed a technique to fabricate ultrathin semiconducting films made from a host of exotic materials other than silicon. To demonstrate their technique, the researchers fabricated flexible films made from gallium arsenide, gallium nitride, and lithium fluoride — materials that exhibit better performance than silicon but until now have been prohibitively expensive to produce in functional devices.
