A volcano in Iceland is erupting for the fourth time in 3 months, sending plumes of lava skywards

Posted by in category: climatology

GRINDAVIK, Iceland (AP) — A volcano in Iceland erupted Saturday evening for the fourth time in three months, sending orange jets of lava into the night sky.

Iceland’s Meteorological Office said the eruption opened a fissure in the earth about 3 kilometers (almost 2 miles) long between Stóra-Skógfell and Hagafell mountains on the Reykjanes Peninsula.

The Met Office had warned for weeks that magma — semi-molten rock — was accumulating under the ground, making an eruption likely.

Liquid Lightning: Nanotechnology Unlocks New Energy

Posted by in categories: climatology, nanotechnology

EPFL researchers have discovered that nanoscale devices harnessing the hydroelectric effect can harvest electricity from the evaporation of fluids with higher ion concentrations than purified water, revealing a vast untapped energy potential.

Evaporation is a natural process so ubiquitous that most of us take it for granted. In fact, roughly half of the solar energy that reaches the earth drives evaporative processes. Since 2017, researchers have been working to harness the energy potential of evaporation via the hydrovol~aic (HV) effect, which allows electricity to be harvested when fluid is passed over the charged surface of a nanoscale device. Evaporation establishes a continuous flow within nanochannels inside these devices, which act as passive pumping mechanisms. This effect is also seen in the microcapillaries of plants, where water transport occurs thanks to a combination of capillary pressure and natural evaporation.

Although hydrovoltaic devices currently exist, there is very little functional understanding of the conditions and physical phenomena that govern HV energy production at the nanoscale. It’s an information gap that Giulia Tagliabue, head of the Laboratory of Nanoscience for Energy Technology (LNET) in the School of Engineering, and PhD student Tarique Anwar wanted to fill. They leveraged a combination of experiments and multiphysics modelling to characterize fluid flows, ion flows, and electrostatic effects due to solid-liquid interactions, with the goal of optimizing HV devices.

Researchers reach new AI benchmark for computer graphics

Posted by in categories: climatology, mapping, robotics/AI

Computer graphic simulations can represent natural phenomena such as tornados, underwater, vortices, and liquid foams more accurately thanks to an advancement in creating artificial intelligence (AI) neural networks.

Working with a multi-institutional team of researchers, Georgia Tech Assistant Professor Bo Zhu combined computer graphic simulations with machine learning models to create enhanced simulations of known phenomena. The new benchmark could lead to researchers constructing representations of other phenomena that have yet to be simulated.

Zhu co-authored the paper “Fluid Simulation on Neural Flow Maps.” The Association for Computing Machinery’s Special Interest Group in Computer Graphics and Interactive Technology (SIGGRAPH) gave it a best paper award in December at the SIGGRAPH Asia conference in Sydney, Australia.

Aurora at Argonne National Laboratory in Lemont on track to be world’s fastest supercomputer

Posted by in categories: climatology, supercomputing

The Aurora supercomputer at Argonne National Laboratory in Lemont, IL, could soon be the world’s fastest. It could revolutionize climate forecasting.

LEMONT, Ill. (WLS) — This is what scientists at Argonne National Laboratory in Lemont call a node: six huge graphics processors and two large CPUs cooled with water to make major calculations a cinch.

Argonne’s new supercomputer doesn’t just have one node, 10 or 100, instead it has 10,000 of them. Each single rack of nodes weighs eight tons and are cooled by thousands of gallons of water.

Space Accident Means Tardigrades May Have Contaminated The Moon

Just over five years ago, on 22 February 2019, an unmanned space probe was placed in orbit around the Moon.

Named Beresheet and built by SpaceIL and Israel Aerospace Industries, it was intended to be the first private spacecraft to perform a soft landing. Among the probe’s payload were tardigrades, renowed for their ability to survive in even the harshest climates.

Chemical etching method opens pores for fuel cells and more

Posted by in categories: chemistry, climatology, economics, sustainability

A chemical etching method for widening the pores of metal-organic frameworks (MOFs) could improve various applications of MOFs, including in fuel cells and as catalysts. Researchers at Nagoya University in Japan and East China Normal University in China developed the new method with collaborators elsewhere in Japan, Australia, and China, and their work was published in the Journal of the American Chemical Society.

MOFs are composed of metal clusters or ions interconnected by carbon-based (organic) linker groups. Varying the metallic and organic components generates a variety of MOFs suitable for a wide range of applications, including catalysis, , and gas storage.

Some MOFs have clear potential for catalyzing the inside fuel cells, which are being explored as the basis of renewable energy systems. Because they don’t use , fuel cells could play a key role in the transition to a low-or zero-emissions economy to combat climate change.
