Metallic Bond

The electronic interaction between buried single transitional metal and adjacent aluminum atoms via metallic bonding can be well demonstrated.

20 years on, Kit Chapman investigates how a scientific scandal unfolded

Cooler bonding, microfluidics, and engineered TIMs help get the heat out.

Two recent preprints in physics archive (arXiv) have called the attention as they claim experimental evidence that a Cu-substituted apatite material (called LK-99) exhibits superconductivity at room temperature and pressure. If this proves to be true, LK-99 will be the holy grail of superconductors. In this work, we used Density-Functional Theory calculations to elucidate some key features of the electronic…

The earth contains a lot of titanium - it's the ninth most abundant element in the earth's crust. By mass, there's more titanium in the earth's crust than carbon by a factor of nearly 30, and more titanium than copper by a factor of nearly 100. But despite its abundance, it's only recently that civilization has been able to use titanium as a metal (titanium dioxide has been in use somewhat longer as a paint…

Physicists are learning more about the bizarre behavior of "strange metals," which operate outside the normal rules of electricity.

Scientists from The University of Manchester have managed to successfully make a transuranium complex where the central metal, here neptunium, forms a multiple bond to just one other element. Enabling study of such a bonding interaction in isolation for the first time is a key breakthrough for nuclear waste clean-up.

Scientists have unveiled the chemical secrets of Promethium, a rare element discovered in 1945

MIT Haystack Observatory scientists aim to study the April 8 solar eclipse with four different instruments. Their observations will help scientists understand how the atmosphere reacts to sudden changes in solar radiation, such as solar storms and flares.

The new map looked at light from just after the universe was born.

An international research team gained new insights into the chemical properties of the superheavy element flerovium—element 114—at the accelerator facilities of the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt. The measurements show that flerovium is the most volatile metal in the periodic table. Flerovium is thus the heaviest element in the periodic table that has been chemically studied.

A team of researchers affiliated with a large number of institutions in the U.S. reports a way to use lanthanide–lanthanide bonds to create more powerful permanent magnets. In their paper published in the journal Science, the group describes a technique to forge several kinds of lanthanide bonds for use in magnets. Lanthanides are the 15 metallic chemical elements numbered 57 to71.

An immense bubble of galaxies, one billion light years wide and located 820 million light-years away, could be fossilized remains of the Big Bang.

@fodagut: LK-99 is quite likely a room-temperature superconductor, or if not it points the way towards building one. But LK-99 is not going to be as easy to synthesize as you have been told, and it's going...…

Liquid metal, planet-like nanodroplets have been successfully formed with a new technique developed at RMIT University, Australia. Like our own planet Earth, the nanodroplets feature an outer "crust," a liquid metal "mantle," and a solid "core."

For decades, the fields of physics and chemistry have maintained that the atoms and molecules that make up the natural world define the character of solid matter. Salt crystals get their crystalline quality from the ionic bond between sodium and chloride ions, metals like iron or copper get their strength from the metallic bonds between iron or copper atoms, and rubbers get their stretchiness from the flexible…

The term aromaticity was initially introduced to describe the properties of molecules with special aromatic odor, such as benzene, and now is considered as one of the most important concepts in chemistry. It is widely used to account for the unusual stability of aromatic compounds arising from delocalization of electrons. Aromaticity can be assessed by various aromatic criteria, such as the Hückel 4n+2 rule,…
