When a voltage is applied to a conductor, an electrical field is generated, and charges in the conductor feel the force due to the electrical field. The current density that results depends on the electrical field and the properties of the material. In some materials, including metals at a given temperature, the current density is approximately proportional to the electrical field. In these cases, the current density can be modeled as: where σ is the electrical conductivity and is represented...

When a current moves through any conductor, the conductor causes some level of difficulty for the current to flow. The measure of that difficulty is known as the resistance of the material and is represented by R. Every material has its own resistance. In the case of conductors, heat is emitted whenever a current passes through them. Resistance depends on the resistivity of the material. Resistivity is a characteristic of the material used to fabricate electrical components, whereas the...

Here, we present a detailed protocol for the isolation and identification of antibiotic-resistant bacteria from water and the molecular characterization of their antibiotic resistance genes (ARGs). The use of culture-based and non-culture-based (metagenomic analysis) techniques provides complete information about the total bacterial diversity and the total pool of different ARGs present in freshwaters from Mumbai, India.

Drug resistance to targeted therapeutics is widespread and the need to identify mechanisms of resistance--prior to or following clinical onset--is critical for guiding alternative clinical management strategies. Here, we present a protocol to couple derivation of drug-resistant lines in vitro with sequencing to expedite discovery of these mechanisms.
FAQs
Microstructure affects how localized damage develops, while fracture toughness influences whether an initiated crack can propagate through the material. A structure that better limits crack growth can reduce the amount of material lost after impact or concentrated loading. Considering both properties helps engineers explain why materials with similar surface hardness may still show different resistance to edge or surface damage.
Hardness is one factor in chippage resistance, but it does not describe every feature governing localized fracture. Fracture toughness, microstructural characteristics, and residual stresses also affect crack initiation and propagation. For this reason, engineering comparisons should consider the combined material response rather than treating hardness as a complete measure of performance under contact or impact.
Residual stresses are internal stresses retained within a material and can influence how cracks initiate and propagate during concentrated loading. Their effect is therefore part of the material’s overall chippage response, alongside hardness, fracture toughness, and microstructure. Including residual stress in material assessment gives engineers a more complete basis for interpreting localized fracture and material loss.
Engineers evaluate chippage resistance by comparing how candidate materials respond to localized impact, contact, or concentrated loading, with attention to resulting fracture and material loss. The assessment can be applied to ceramics, coatings, cutting tools, and other components exposed to mechanical damage. Relating observed damage to microstructure, hardness, fracture toughness, and residual stresses supports meaningful material comparisons.
Ceramics, coatings, cutting tools, and other components subjected to repeated mechanical damage are important targets for improved chippage resistance. Limiting localized loss in these applications can help preserve dimensional accuracy and surface integrity. That preservation supports functional performance over longer service periods and can reduce the need for maintenance or replacement.
Testing can reveal how effectively a material withstands localized fracture and material loss under mechanically demanding conditions. Researchers can use the results to compare candidate materials and connect performance with microstructural design, hardness, fracture toughness, and residual stresses. These findings guide the development of more reliable components whose dimensions, surfaces, and functions remain usable for longer.
