Ammonia synthesis by mechanocatalysis in a ball mill
A breakthrough in the fight against hunger, three Nobel Prizes, and 150 million tonnes of annual production—yet still a tricky topic for research: For over 100 years, the chemical industry has been using the Haber-Bosch process to convert atmospher.....»»
A new trail to exoplanets: Team successfully detects ammonia isotopologues in atmosphere of cold brown dwarf
They reveal the origin of wine, the age of bones and fossils, and they serve as diagnostic tools in medicine. Isotopes and isotopologues—molecules that differ only in the composition of their isotopes—also play an increasingly important role in a.....»»
Poison expert allegedly poisoned wife—with a shockingly toxic gout drug
Colchicine is centuries old, but the line between toxic and nontoxic is still blurry. Enlarge / Ball-and-stick model of the colchicine molecule. (credit: Wikimedia | Ben Mills) A Minnesota doctor who had worked for a poi.....»»
Agronomists find green way to mitigate the effects of soil salinity
Most crops are sensitive to soil salinity. Excess salts cause salt stress—plants lack water, photosynthesis is suppressed, respiration worsens, chlorophyll breaks down, and potassium ions leak. Water-soluble toxic salts stimulate the synthesis of r.....»»

Mattel has launched a series of Barbie dolls, celebrating the Apple TV+ hit with the Ted action figuring coming with accessories including a soccer ball.A boxed-up "Ted Lasso" Barbie doll may be just kenough for a great Christmas presentFrom being th.....»»
New ammonia reaction could offer a sustainable source of nitrogen
A big goal in chemistry is to find a simple way to produce amines from ammonia and unsaturated hydrocarbons. Catalytic addition to activate and transfer ammonia would not give rise to any waste. Hence, the process would be sustainable......»»
Larger 32-inch iMac Pro rumored to hit store shelves in late 2024
The long-rumored large-screen iMac is still on the way, with a release now rumored for late 2024.24-inch iMacSince the retirement of the iMac Pro, the rumor mill has repeatedly claimed that a large iMac was on the way, with it amping up after the rel.....»»
Vectorial spin-orbital Hall effect of light upon tight focusing and experimental observation in azopolymer films
A soccer player can kick a static ball on its side, forcing the ball to rotate and travel in an arc trajectory, left or right curved, depending on the ball's rotation sense. This requires skill/experience. And if the ball is not static but approaches.....»»
Apple"s rumored iPad event could take place on Tuesday
Apple is allegedly preparing to introduce new iPad models with a minor spec-bump as soon as Tuesday, but there are reasons to doubt the timetable.iPad miniThe rumor mill has discussed iPads repeatedly in recent months, with a late 2023 launch turning.....»»
Local chemical pressure experimentally sensed by optical probe
The practical application of high-pressure metastable materials is hindered by severe synthesis condition, poor yield, and mostly vanishing phase and phenomena after decompressing. The scaled-up capture of these metastable states to ambient pressure.....»»
Want to watch the sun safely with a large group? disco ball
The upcoming solar eclipses and the current high sunspot activity means it's a great time to observe the sun. Eclipses also mean that large groups of people will be together to view these events. However, rule #1 for astronomy is to never look at the.....»»
The Earth"s iron core isn"t just a solid mass
A new study by physicists discovers that the Earth's dense inner core is made up of constantly switching iron atoms. According to a new "holy grail" scientific discovery, the blazing-hot ball of metal at the center of the Earth's core is actual.....»»
Machine learning reveals how to dissolve polymeric materials in organic solvents
Dissolving polymers with organic solvents is the essential process in the research and development of polymeric materials, including polymer synthesis, refining, painting, and coating. Now more than ever recycling plastic waste is a particularly impe.....»»
