Bonding in Metals

Bonding in Metals

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 Solids

Metallic Solids

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....

Protein Folding Quality Check in the RER

Protein Folding Quality Check in the RER

ER is the primary site for the maturation and folding of soluble and transmembrane secretory proteins. The calnexin cycle is a specific chaperone system that folds and assesses the confirmation of N-glycosylated proteins before they can exit the ER lumen. The primary players of this quality check pipeline are the lectins, ER-resident chaperones, and a glucosyl transferase enzyme. In case the calnexin system in the lumen fails to salvage a misfolded protein, it is transported to the cytoplasm...

Alkali Metals

Alkali Metals

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 Bonds

Metal-Ligand Bonds

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 Metals

Properties of Transition Metals

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.

Summary

Travellers with metal implants like joint replacements or fracture hardware may trigger airport security metal detectors. While medical documentation can help, additional screening is often unavoidable due to security procedures.

Area of Science:

Orthopaedic Surgery
Trauma Surgery
Airport Security Screening

Background:

Annually, 65,000 joint replacements and 300,000 fracture treatments are performed in the Netherlands.
Travellers with metal implants face uncertainty regarding airport security procedures.
European airport security involves metal detectors and millimeter wave scanners.

Purpose of the Study:

To clarify the implications of metal implants during airport security checks.
To inform travellers and healthcare providers about potential security screening outcomes.

Main Methods:

Analysis of airport security procedures and screening technologies.
Comparison of metal detector and millimeter wave scanner detection capabilities for implants.

Main Results:

Metal detectors have a higher detection rate for internal metal implants compared to millimeter wave scanners.
Millimeter wave scanners' radio waves have limited skin penetration.
Medical documentation may assist but does not eliminate further checks.

Conclusions:

Travellers with orthopaedic implants should anticipate potential secondary screening at airports.
Understanding the technology used in security checks can help manage expectations.
