3D-printed microstructure forest facilitates solar steam generator desalination      (via sciencedaily.com)     Original source 

Faced with the world's impending freshwater scarcity, researchers turned to solar steam generators, which are emerging as a promising device for seawater desalination. The team sought design inspiration from trees and harnessed the potential of 3D printing. They present technology for producing efficient SSGs for desalination and introduces a novel method for printing functional nanocomposites for multi-jet fusion. Their SSGs were inspired by plant transpiration and are composed of miniature tree-shaped microstructures, forming an efficient, heat-distributing forest.

Aluminum scandium nitride films: Enabling next-gen ferroelectric memory devices      (via sciencedaily.com)     Original source 

Aluminum scandium nitride thin films could pave the way for the next generation of ferroelectric memory devices, according to a new study. Compared to existing ferroelectric materials, these films maintain their ferroelectric properties and crystal structure even after heat treatment at temperatures up to 600 C in both hydrogen and argon atmospheres. This high stability makes them ideal for high-temperature manufacturing processes under the H2-included atmosphere used in fabricating advanced memory devices.

3D printing of light-activated hydrogel actuators      (via sciencedaily.com)     Original source 

An international team of researchers has embedded gold nanorods in hydrogels that can be processed through 3D printing to create structures that contract when exposed to light -- and expand again when the light is removed. Because this expansion and contraction can be performed repeatedly, the 3D-printed structures can serve as remotely controlled actuators.

New dawn for space storm alerts could help shield Earth's tech      (via sciencedaily.com)     Original source 

Space storms could soon be forecasted with greater accuracy than ever before thanks to a big leap forward in our understanding of exactly when a violent solar eruption may hit Earth. Scientists say it is now possible to predict the precise speed a coronal mass ejection (CME) is travelling at and when it will smash into our planet -- even before it has fully erupted from the Sun.

Weather experts discover new effect of storm -- in a teacup      (via sciencedaily.com)     Original source 

A new study reveals that Storm Ciaran cut an invisible path of mayhem across southern Britain last autumn, destroying any possibility that 20 million people could have a proper cup of tea at breakfast. The storm's record-breaking low pressure meant the boiling point of water was below the crucial 100 degrees Celsius required for a decent cuppa.

Capturing carbon with energy-efficient sodium carbonate-nanocarbon hybrid material      (via sciencedaily.com)     Original source 

Carbon capture is a promising approach for mitigating carbon dioxide (CO2) emissions. Different materials have been used to capture CO2 from industrial exhaust gases. Scientists developed hybrid CO2 capture materials containing sodium carbonate and nanocarbon prepared at different temperatures, tested their performance, and identified the optimal calcination temperature condition. They found that the hybrid material exhibits and maintains high CO2 capture capacity for multiple regeneration cycles at a lower temperature, making it cost- and energy-effective.

Groundbreaking study reveals oceanic seabirds chase tropical cyclones      (via sciencedaily.com)     Original source 

A new study reveals that the rare Desertas Petrels (Pterodroma deserta), a wide-ranging seabird in the North Atlantic, exhibit unique foraging behaviors during hurricane season. Contrary to other pelagic seabirds, these petrels do not avoid intense tropical cyclones but instead exploit the dynamic conditions for their benefit, providing new insights into the impact of cyclones on open ocean marine life.
