Suppressing strain propagation in ultrahigh-Ni cathodes during fast charging via epitaxial entropy-assisted coating

Posted by in category: futurism

Layered Ni-rich oxide cathodes are susceptible to challenges with surface reconstruction and strain propagation, limiting their cyclability. The authors propose a solution involving oriented attachment-driven reactions, utilizing Wadsley–Roth nanocrystals and layered oxide to induce an epitaxial entropy-assisted coating, effectively addressing these issues.

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.

Intelligence is a Process

Posted by in category: robotics/AI

In the case of artificial intelligence, we have a problem. There is no clear, settled definition of natural intelligence. If we are not sure what the natural thing is, how can we know what the artificial thing ought to be?

In fact, I want to claim that intelligence is not a thing at all. It is an ongoing process. It is like science. You should not think of science as a body of absolute truth. Instead, think of the scientific method as a way of pursuing truth.

One should resist the temptation to think of intelligence as a huge lump of knowledge that an entity possesses. Memorizing the encyclopedia does not constitute intelligence.

Researchers develop ‘foundational tool’ for understanding behavior of hydride superconductors at high pressure

Posted by in categories: particle physics, transportation

Hydrogen (like many of us) acts weird under pressure. Theory predicts that when crushed by the weight of more than a million times our atmosphere, this light, abundant, normally gaseous element first becomes a metal, and even more strangely, a superconductor—a material that conducts electricity with no resistance.

Scientists have been eager to understand and eventually harness superconducting hydrogen-rich compounds, called hydrides, for practical applications—from levitating trains to particle detectors. But studying the behavior of these and other materials under enormous, sustained pressures is anything but practical, and accurately measuring those behaviors ranges somewhere between a nightmare and impossible.

Like the calculator did for arithmetic, and ChatGPT has done for writing five-paragraph essays, Harvard researchers think they have a foundational tool for the thorny problem of how to measure and image the behavior of superconductors at high pressure.

Attitude Bias at Procrastination’s Root

Posted by in category: futurism

Do I want to do this now?

Summary: New research delves into how valence weighting bias—people’s tendency to prioritize negative or positive attitudes—plays a crucial role in procrastination. By studying individuals’ responses to tasks like tax filing and academic research participation, the researchers found a strong link between a negative-leaning attitude and the tendency to delay tasks.

Additionally, interventions that balanced participants’ valence weighting bias showed promise in reducing procrastination, suggesting that this psychological bias might be a key target for improving decision-making and task completion. This insight opens new avenues for addressing procrastination by adjusting how individuals weigh positive and negative signals when faced with decisions.

A Randomized, Controlled Clinical Trial Demonstrates Improved Cognitive Function in Senior Dogs Supplemented with a Senolytic and NAD+ Precursor Combination

Aging reversed in dogs face_with_colon_three

Age-related decline in mobility and cognition are associated with cellular senescence and NAD+ depletion in dogs and people. A combination of a novel NAD+ precursor and senolytic, LY-D6/2 was examined in this randomized controlled trial. Seventy dogs were enrolled and allocated into placebo, low or full dose groups. Primary outcomes were change in cognitive impairment measured with the owner-reported Canine Cognitive Dysfunction Rating (CCDR) scale and change in activity measured with physical activity monitors. Fifty-nine dogs completed evaluations at the three-month primary endpoint, and 51 reached the six-month secondary endpoint. There was a significant difference in CCDR score across treatment groups from baseline to the primary endpoint (p=0.02) with the largest decrease in the full dose group. There were no significant differences between groups in changes in measured activity. However, the proportion of dogs that improved in frailty and owner-reported activity levels and happiness was higher in the full dose group than other groups. Adverse events occurred equally across groups. All groups showed improvement in cognition, frailty, and activity suggesting placebo effect and benefits of trial participation. We conclude that LY-D6/2 significantly improves owner-assessed cognitive function and may have broader effects on frailty, activity and happiness as reported by owners.

The authors have declared no competing interest.

Insomnia: Insomnia is a common sleep disorder

Posted by in category: neuroscience

Insomnia is a common sleep disorder. If you have it, you may have trouble falling asleep, staying asleep, or both. As a result, you may get too little sleep or have poor-quality sleep. You may not feel refreshed when you wake up.

What are the types of insomnia?

Insomnia can be acute (short-term) or chronic (ongoing). Acute insomnia is common. Common causes include stress at work, family pressures, or a traumatic event. It usually lasts for days or weeks.
