Summary
This study reviews advances in doping metals with functional materials, creating novel properties for applications in catalysis, medicine, and energy storage. Doped metals offer unique functionalities beyond simple surface adsorption.
Area of Science:
- Materials Science
- Nanotechnology
- Chemistry
Background:
- Traditional metal functionalization relies on surface adsorption (2D).
- A novel doping methodology allows integration of functional molecules, polymers, enzymes, and nanoparticles within metals (3D).
- This doping process creates materials with combined or emergent synergistic properties.
Purpose of the Study:
- To review recent progress (past four years) in the field of doped metals.
- To highlight advancements in methodologies for creating doped metallic thin films.
- To showcase diverse applications of doped metals.
Main Methods:
- Development of unique materials' methodologies for doping metals.
- Fabrication of metallic doped thin films.
- Characterization of novel properties and functionalities.
Main Results:
- Doping enables metals (e.g., gold, silver, copper, iron) to exhibit combined or synergistic properties.
- Applications demonstrated include advanced catalysis, biocatalysis, enhanced corrosion resistance, novel electrochemistry (batteries), and bioactivity.
- Doping is a 3D process, distinct from 2D adsorption, leading to unique functionalities.
Conclusions:
- Doped metals represent a significant advancement over surface-adsorbed materials.
- Recent progress has expanded methodologies and demonstrated a wide array of practical applications.
- This field holds substantial potential for future innovations in materials science and technology.

02:37Metallic Solids
20.9K
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.

03:06Alkali Metals
25.0K
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).

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...

02:58Properties of Transition Metals
30.1K
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.

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
