Tungsten is a metal in group VIB of the periodic table with atomic number 74, an atomic weight of 183.85, and a density of 19.3 Mg/m 3. Its melting point is 3410 C, and it boils at 5930 C. In the ...

Catalytic activity can be modulated by tuning local atomic structure. Here, the authors show that tungsten trioxide, which is usually inert, can be converted into an efficient electrocatalyst for ...

Amin Aziz, a Ph.D. candidate in Alem's group and lead author, produced the STEM imaging and spectroscopy that showed the fine atomic structure of the alloy samples and their electronic properties.

By creating atomic chains in a two-dimensional crystal, researchers at Penn State believe they have found a way to control the direction of materials properties in two and three dimensional ...

NUS scientists have demonstrated a general approach for characterizing the atomic structure and electronic and magnetic properties of two-dimensional (2-D) magnetic insulators using scanning ...

To fully understand how nanomaterials behave, one must also understand the atomic-scale deformation mechanisms that determine their structure and, therefore, their strength and function. Researchers ...

Tungsten heavy alloys show promise for nuclear fusion energy development, according to new research conducted at PNNL.

What happens when the smallest building blocks of matter refuse to play by the rules of traditional physics? For decades, ...

To fully understand how nanomaterials behave, one must also understand the atomic-scale deformation mechanisms that determine their structure and, therefore, their strength and function.

The atomic motion in a 2-D material, tungsten disulfide, is shown in this animation. In this phonon mode (known as longitudinal optical mode or LO), the selenium atoms (yellow) rotate clockwise while ...
