Researchers at the U.S. Department of Energy have discovered that sodium bismuthate can exist as a form of quantum matter called a 3D topological Dirac semimetal (3DTDS). Read on to know more. 

There is a growing interest paired with attempts in creating a synthesis machine or a ‘robo-chemist’ that would take over the traditional organic chemistry. Such a device would offer a diversity of compounds for investigation by researchers developing drugs, agrochemicals, or materials. Read on to find out more. 

In a recent study, researchers were able to determine the chirality of a gaseous sample by imaging its molecular structure. Read on to know more. 

In a study that challenges the fundamental rules of classical chemistry, W. Zhang et al. report compounds that violate textbook rules—NaCl3, NaCl7, Na3Cl2, Na2Cl, and Na3Cl. Read on to know more. 

Graphene is the world’s thinnest and strongest material, made of a single sheet of carbon atoms arranged in a hexagonal honeycomb pattern. But a team of researchers has discovered graphene’s ability to withstand the onslaught of high-speed projectiles. Read on to find out more.

It is well known that a lump of sodium or potassium metal thrown in water causes an explosion. The science behind this is that alkali metals release hydrogen gas from the water, which gets ignited. However, Pavel Jungwirth and his collaborators at the Czech Academy of Sciences in Prague believe that there is another reason behind the phenomenon. Read on to find out more. 

The carbon dating processes require an accelerator mass spectrometer that can measure the amount of carbon-14, or radiocarbon, present in bones, wood, fabrics or anything of biological origin. However, the process can take up to several weeks as there are only about 100 facilities in the world that have spectrometers. Researchers from Istituto Nazionale di Ottica (INO) in Italy have devised a new approach called saturated-absorption cavity ring-down (SCAR) that can cut down on the time and expense it takes to carbon date samples.

Diamond is considered to be the hardest material known to man. However, a newly discovered substance named Q-carbon has claimed the title of being the hardest material formed from carbon. A team of researchers at North Carolina State University, headed by Jagdish Narayan, focused a very short pulse of laser light onto carbon for 200 nanoseconds and then cooled it down, a process that is called quenching. This yielded minuscule synthetic diamond “seeds” of Q-carbon from which the researchers were able to make gems. Read more about their research here.

Professor Hod Lipso, a roboticist at Columbia Engineering who works in the areas of artificial intelligence and digital manufacturing, has along with his students developed a prototype of a 3D food printer. This machine, which resembles a coffee machine, is able to generate edible items such as pastes, gels, powders, and liquid ingredients. Read more about Professor Lipso's invention here.

One of the most conventional ways of creating fusion energy is using high-power lasers to heat material. However, this process is slow because the energy from the laser targets and heats up the electrons, which in turn heat up the ions. Now theoretical physicists from Imperial College London have developed a method by which certain metals can be heated to ten million degrees, which is hotter than the Sun’s core, in less than a million millionth of a second.
