A method is described for the preparation of a 3-dimensional matrix consisting of collagen type I and primary human fibroblasts. This organotypic gel serves as a useful substrate to assess invasive cell migration because it mimics basic features of tissue stroma and is amenable to many forms of microscopy.

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”. Electron Sea Model Most metal atoms do not possess enough valence electrons to enter into an ionic or covalent bonding. However, the valence electrons in metal atoms are loosely held due to their low electronegativity or attraction with the nucleus. The ionization energy of metal atoms (energy required to remove an electron from...

Medial canthopexy allows correction of the position and fixation of the medial canthal tendon. Due to the technical difficulties of this procedure, there is a need for a detailed protocol for educational purposes. Here, we describe a standardized reproducible technique for bilateral medial transnasal canthopexy by an orbitonasal approach.

Source: Faisal Alamgir, School of Materials Science and Engineering, Georgia Institute of Technology, Atlanta, GA X-ray diffraction (XRD) is a technique used in materials science for determining the atomic and molecular structure of a material. This is done by irradiating a sample of the material with incident X-rays and then measuring the intensities and scattering angles of the X-rays that are scattered by the material. The intensity of the scattered X-rays are plotted as a function of the...

Are You Smart or Hardworking? How Praise Influences Children's Motivation

Source: Laboratories of Judith Danovitch and Nicholaus Noles—University of Louisville Imagine teaching two children how to skate. It is a hard task for both of them, and they fall down frequently. After falling down for the first time, one child says that skating is too hard and wants to go home. The other child seems to enjoy the challenge and eagerly gets back up after falling down each time. Why do the children have such different attitudes about the same task? One reason may be that they...
FAQs
Closely packed layers of metal atoms can slide past one another when compressive force is applied. This layered movement allows the material to change shape permanently rather than immediately fracture. The arrangement therefore helps explain why certain metals can be processed into sheets or foils while retaining an intact atomic structure.
Delocalized electrons continue to hold the metal atoms together as neighboring atomic layers shift. Because the bonding is not limited to one fixed pair of atoms, sliding does not necessarily destroy the overall structure. This bonding behavior is central to understanding why metallic materials can tolerate substantial reshaping under compression.
The two properties describe deformation under different loading conditions. Malleability concerns permanent shaping under compression, such as hammering or rolling, whereas ductility concerns deformation under tension. Distinguishing them helps chemistry and materials science describe how a material is likely to respond during a particular forming process.
These metals provide clear examples of materials that can be hammered or rolled into sheets and foils. Their inclusion illustrates how malleability connects atomic bonding and layer movement with observable processing behavior. Comparing such examples helps learners relate a microscopic chemical explanation to a practical change in material form.
Measurement and comparison establish how suitable different materials are for processes that require permanent shaping under compression. The resulting comparisons support decisions in manufacturing, packaging, construction, and chemical equipment. In chemistry, this property provides a basis for relating a material’s physical response to its intended structural or processing role.
Malleability is relevant wherever metals must be converted into useful shapes without breaking during compressive processing. It informs material selection for manufactured products, packaging materials, construction components, and chemical equipment. These applications connect a physical property studied in chemistry with practical requirements for forming and using metal products.
