Bonding in Metals02:32

Bonding in Metals

52.5K
Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.

Metallic Solids02:37

Metallic Solids

20.7K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Alkali Metals03:06

Alkali Metals

24.8K
Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).

Metal-Ligand Bonds02:51

Metal-Ligand Bonds

24.3K
The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Properties of Transition Metals02:58

Properties of Transition Metals

29.9K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.

Magnetic Field Due to Two Straight Wires01:18

Magnetic Field Due to Two Straight Wires

4.7K
Consider two parallel straight wires carrying a current of 10 A and 20 A in the same direction and separated by a distance of 20 cm. Calculate the magnetic field at a point "P2", midway between the wires. Also, evaluate the magnetic field when the direction of the current is reversed in the second wire.

Area of Science:

  • Materials Science
  • Condensed Matter Physics
  • Nanotechnology

Background:

  • Two-dimensional (2D) van der Waals (vdW) materials are foundational for dimensional material design.
  • Quasi-one-dimensional (quasi-1D) vdW materials, despite their potential, are under-explored compared to 2D counterparts.
  • Molybdenum disulfide (MoS2) is a prominent 2D vdW material with significant electronic applications.

Purpose of the Study:

  • To fabricate quasi-1D MoS2 nanoscrolls from 2D MoS2 sheets.
  • To investigate the formation, stability, and electronic properties of these quasi-1D MoS2 nanoscrolls.
  • To explore the potential for transitioning MoS2 from a 2D semiconductor to a 1D metallic state.

Main Methods:

  • Chemical Vapor Deposition (CVD) to grow 2D triangular MoS2 sheets.
  • Direct fabrication of quasi-1D MoS2 nanoscrolls from the 2D sheets.
  • Optical spectroscopy and electrical transport measurements.
  • Density-functional theory (DFT) calculations for theoretical analysis.

Main Results:

  • Successful fabrication of quasi-1D MoS2 nanoscrolls initiated from the armchair edges of triangular 2D MoS2 sheets.
  • MoS2 nanoscrolls exhibit unique electronic properties, differing from their 2D counterparts in carrier mobility and contact characteristics.
  • Demonstrated transition from semiconducting behavior in 2D MoS2 sheets to metallic behavior in the quasi-1D MoS2 nanoscrolls.

Conclusions:

  • Quasi-1D MoS2 nanoscrolls can be effectively synthesized from 2D MoS2 precursors.
  • The unique electronic properties of MoS2 nanoscrolls open new avenues for 1D electronic devices.
  • This fabrication approach is promising for exploring novel physical and chemical properties in 1D transition metal dichalcogenides.
