Transition Metal

Researchers compressed infrared light to 10% of its wavelength using a thin strontium titanate film, paving the way for advanced infrared imaging.

Mining firm Rare Earths Norway says it has discovered Europe's largest proven deposit of highly prized rare earth elements, potentially reflecting a watershed moment for both the Nordic country and the broader region.

Recycling more of the copper, aluminum, and other minerals in our old electronics could reduce the need for mining

Silicon-based electronics are approaching their physical limitations and new materials are needed to keep up with current technological demands. Two-dimensional (2D) materials have a rich array of properties, including superconductivity and magnetism, and are promising candidates for use in electronic systems, such as transistors. However, precisely controlling the properties of these materials is extraordinarily…

There is an ever-present struggle to reduce carbon-based energy sources and replace them with low or no-carbon alternatives. The process of splitting water could be the resolution.

A new electrocatalyst made of nickel (Ni), iron (Fe) and silicon (Si) that decreases the amount of energy required to synthesize H2 from water has been manufactured in a simple and cost-effective way, increasing the practicality of H2 as a clean and renewable energy of the future.

With a slew of impressive properties, transition metal carbides, generally referred to as MXenes, are exciting nanomaterials being explored in the energy storage sector. MXenes are two-dimensional materials that consist of flakes as thin as a few nanometers.

A research group has synthesized a 2D copper-based complex and expanded it into a 3D structure by adding H4SiW12O40 and rare earth metal. Through this synthesis method the team obtained three isostructural 3d−4f metal-incorporated POMs.

Electronic nematic order in kagome materials has thus far been entangled with charge density waves. Now it is finally observed as a stand-alone phase in a titanium-based Kagome metal, a team of researchers led by Boston College physicists reported recently in Nature Physics.

The Rydberg state is widespread in a variety of physical platforms such as atoms, molecules, and solids. In particular, Rydberg excitons are highly excited Coulomb-bound states of electron-hole pairs, first discovered in the semiconductor material Cu2O in the 1950s.

Shear band formation is not typically a good sign in a material—the bands often appear before a material fractures or fails. But materials science and engineering researchers at the University of Wisconsin–Madison have found that shear bands aren't always a negative; under the right conditions, they can improve the ductility, or the plasticity, of a material.

An MIT-led international team reports a powerful tool for studying and tuning atomically thin materials called moiré systems, where exotic phenomena including superconductivity can occur. The work could lead to heady applications in novel electronics and more.

Materials with superior mechanical strengths are crucial to many areas of modern industries and the scientific enterprise by providing cutting and drilling tools, structural components, protective coatings, and abrasives that find wide applications. Solid solution strengthening is a well-established method to enhance hardness of metals by introducing solute atoms to create local distortions in the crystal lattice,…

A research team led by Prof. Qin Xiaoying from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has improved the thermoelectric performance of an n-type transition metal selenide, Bi2Te2.7Se0.3 (BTS), by incorporating MnSb2Se4 (MSS) nanoinclusions. Results were published in two articles in the Chemical Engineering Journal.

Magnetic materials with a triangular lattice have been the focus of numerous research studies, as theoretical predictions suggest that they could exhibit spin liquid states. These are quantum phases of matter that present interesting characteristics, such as quantum entanglement and fractionalized excitations.

A new study conducted by a team of scientists from the Max Planck Institute for Chemistry (MPIC) reveals that the adverse health effects of fine particulate matter (PM2.5) are attributable to the conversion of peroxides into more reactive species such as the hydroxyl radical (OH) rather than the direct chemical production of hydrogen peroxide (H2O2) as previously thought.

Today, over half of the total energy produced from fossil fuels is discarded as waste heat, which accelerates global warming. If we could convert the waste heat into a more useful form of energy like electricity, we could minimize fuel consumption and reduce our carbon footprint. In this regard, thermoelectric energy conversion has gained momentum as a technology for generating electricity from waste heat.

Seeking to modernise the UK's energy system and maximise the potential of renewables, the British government has awarded £30 million to three pioneering companies to develop new

A new review published in Science China Chemistry has summarized recent progresses in the oxidation of methane via both thermocatalysis and photocatalysis through the lens of environmental remediation. The review was led by Prof. Junwang Tang, Department of Chemical Engineering, University College London; and Department of Chemical Engineering, Tsinghua University.
