Non-lithium alternatives: Reliance completes sodium-ion acquisition, Amazon tries ‘membrane-free’ flow battery

Posted by in categories: chemistry, sustainability, transportation

India’s Reliance Industries has completed the takeover of sodium-ion battery company Faradion, while Amazon is set to trial a novel flow battery technology.

Lithium-ion (Li-ion) presently dominates the global energy storage and electric vehicle (EV) sectors as the battery chemistry of choice.

Holographic 3D Printing has the potential to Revolutionize Multiple Industries

Posted by in categories: 3D printing, chemistry, holograms

A pioneering technique shows how sound can be used to create entire objects quickly and at once. Researchers at Concordia have developed a novel method of 3D printing that uses acoustic holograms. And they say it’s quicker than existing methods and capable of making more complex objects.

The process, called holographic direct sound printing (HDSP), is described in a recent article in the journal Nature Communications. It builds on a method introduced in 2022 that described how sonochemical reactions in microscopic cavitations regions — tiny bubbles — create extremely high temperatures and pressure for trillionths of a second to harden resin into complex patterns.

Now, by embedding the technique in acoustic holograms that contain cross-sectional images of a particular design, polymerization occurs much more quickly. It can create objects simultaneously rather than voxel-by-voxel.

Huntington’s Discovery Could Lead to New Treatments

Posted by in categories: biotech/medical, chemistry

“This research marks the first time that we have been able to identify a specific chemical change that is unique to the development of Huntington’s disease, which opens the possibility of developing new tests to study the early changes of the disease before irreversible damage occurs.”


U.K. and German researchers are hopeful that their discovery of a key biochemical change involved in the development of Huntington’s disease could lead to its early detection and treatment.

1992, 31 October

Posted by in categories: chemistry, mathematics, physics

On this day in 1992, the Vatican admitted that Galileo was correct in believing that the earth went around the sun.


2. In the first place, I wish to congratulate the Pontifical Academy of Sciences for having chosen to deal, in its plenary session, with a problem of great importance and great relevance today: the problem of ‘the emergence of complexity in mathematics, physics, chemistry and biology

The emergence of the subject of complexity probably marks in the history of the natural sciences a stage as important as the stage which bears relation to the name of Galileo, when a univocal model of order seemed to be obvious. Complexity indicates precisely that, in order to account for the rich variety of reality, we must have recourse to a number of different models.

Nuclear Rockets could Travel to Mars in Half the Time, but designing the Reactors that would Power them isn’t

Posted by in categories: chemistry, nuclear energy, particle physics, space travel

NASA plans to send crewed missions to Mars over the next decade—but the 140 million-mile (225 million-kilometer) journey to the red planet could take several months to years round trip.

This relatively long transit time is a result of the use of traditional chemical rocket fuel. An alternative technology to the chemically propelled rockets the agency develops now is called nuclear thermal propulsion, which uses nuclear fission and could one day power a rocket that makes the trip in just half the time.

Nuclear fission involves harvesting the incredible amount of energy released when an atom is split by a neutron. This reaction is known as a fission reaction. Fission technology is well established in power generation and nuclear-powered submarines, and its application to drive or power a rocket could one day give NASA a faster, more powerful alternative to chemically driven rockets.

‘Brain dead’ man trapped in body heard debate about turning off his life support

A paralysed man who had an extreme form of locked-in syndrome and heard a nurse say he was “brain dead” has become the first ever to recover after hearing medical professionals debating whether or not to switch off his life support.

In 2017, Jacob Haendel was living a normal life as a head chef in Boston, Massachusetts but in the space of a few weeks, his life was turned upside down after he was diagnosed with acute toxic progressive leukoencephalopathy, which progressed into locked-in syndrome and forced his body would slowly shut down. An extreme form of locked-in syndrome is a condition where a patient is aware but cannot move or communicate verbally due to complete paralysis and can be caused by brain trauma, infection or exposure to toxins.
