Intercalation

Goldene in the form of gold monolayer sheets has been prepared by etching away titanium carbide (Ti3C2) slabs from titanium gold carbide (Ti3AuC2).

Membrane separation technology has become one of the most effective methods for water treatment, owing to its advantages of high separation efficiency, convenient operation and low-energy consumption. The membranes prepared from graphene oxide (GO) have received extensive attention for their high water permeability which is attributable to rapid water transport in the atomically smooth sp2 regions (non-oxidized…

Researchers in South Korea have found that molybdenum ditelluride could increase carrier generation in perovskite solar cells. They simulated a cell with a perovskite absorber and a layer made of the new material, and determined that its efficiency could exceed 20%.

As the world's appetite for carbon-based materials like graphite increases, Ohio University researchers presented evidence this week for a new carbon solid they named "amorphous graphite."

Graphene is insanely useful, but very difficult to produce — until now.

This 130-page deck summarizes the most significant developments in the battery industry in 2021. We intend for this report to be a comprehensive and accessible overview of the current state of…

An international team of researchers suggests that all electrochemical energy storage mechanisms exist on a spectrum between physical and chemical retention of ions.

Goldene is a layer of gold a single atom thick. It doesn't look very … goldy?… but it's a major achievement of materials science. Shun Kashiwaya and others: The synthesis…

Ever since the discovery of the two-dimensional form of graphite (called graphene) almost twenty years ago, interest in 2D materials and their special physical properties has skyrocketed. Famously, graphene was produced by exfoliating bulk graphite using sticky tape. Although it was good enough for a Nobel Prize, this method has its drawbacks.

A team of chemists, engineers, material scientists and physicists from Princeton University, Rutgers University and the University of Regensburg has developed a chemical exfoliation technique to produce single-molecule-thick tungsten disulfide ink. The group describes their technique in a paper published in the journal Science Advances.

In a study published in Advanced Materials, a research team led by Prof. Luo Xuan from Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences made a breakthrough in tuning electronic properties of Weyl semimetal Td-MoTe2 by intercalating 3d-element Fe atoms into the van der Waals (vdW) gap, which brought about exotic electronic behaviors as well as the first-time observed magnetic states in…

A superconducting ink made through a simple process called chemical exfoliation could be used to print the cold circuits inside quantum computers and MRI machines

Two-dimensional monolayer nanosheets made from layered perovskite have many desirable properties. However, it has been difficult to create them with tunable bandgaps in the visible region without adding oxygen defects. Recently, researchers from Japan were able to successfully develop chemically stable nanosheets from perovskite oxynitrides which had controllable bandgaps. These nanosheets have immense potential…

Researchers from Tokyo Metropolitan University have successfully threaded atoms of indium metal in between individual fibers in bundles of transition metal chalcogenide nanofibers. By steeping the bundles in indium gas, rows of atoms were able to make their way in between the fibers to create a unique nanostructure via intercalation. Through simulations and resistivity measurements, individual bundles were shown to…

In the lab at least, its materials are stable for over 1,000 cycles.

Single crystals are materials in which the crystal lattice is continuous and unbroken to the edges of the sample, with no grain boundaries. The atoms occupy regular positions, which are repeated indefinitely in space. While polycrystals are made up of many crystal grains or crystallites of varying sizes and orientations, monocrystals consist of a single grain.

For The First Time, A Portable Laser Shock Peening System Has Been Developed for and Demonstrated in A Shipyard Environment and Onboard a U.S. Navy Warship to Combat Aluminum Cracking

Metal-semiconductor junctions, electrical junctions in which a metal is linked to a semiconducting material, are crucial components for numerous electronic and optoelectronic devices. While they are now widely produced and used worldwide, creating good quality junctions that integrate conventional metals and 2D semiconductors can be difficult.

Electronics made using diamond-based chips would have many advantages, but have been hard to make – a new technique involving sticky tape could change that

A new strategy was proposed in the field of aqueous zinc-ion battery to help increase the capacity of the cathodes, making them more efficient, according to a recent study published in ACS Nano.
