We describe the methodology of mechanical exfoliation and deposition of flakes of novel materials with micron-sized dimensions onto substrate, fabrication of experimental device structures for transport experimentation, and the magnetotransport measurement in a dry helium close-cycle cryostat at temperatures down to 0.300 K and magnetic fields up to 12 T.

We present a protocol for the antimicrobial characterization of advanced materials. Here, the antimicrobial activity on material surfaces is measured by two methods that complement each other: one is based on the agar disk diffusion test, and the other is a standard procedure based on the ISO 22196:2007 norm.

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA In contrast to the production of cars or toasters, where millions of identical copies are made and extensive prototype testing is possible, each civil engineering structure is unique and very expensive to reproduce (Fig.1). Therefore, civil engineers must extensively rely on analytical modeling to design their structures. These models are simplified abstractions of reality and are used to...

The Neoclassical Growth Model: Technological Advancement

2025
In the neoclassical growth model, once capital per worker stops increasing, the only way to keep growing is through better technology. This means finding smarter ways to use the same resources to produce more. It doesn’t require more machines or more people—just improvements in how things are done. As technology improves, output per worker rises even if capital stays the same. This leads to higher wages and better living standards over time.The production function includes a term for technology.

Supercritical Nitrogen Processing for the Purification of Reactive Porous Materials

2015
Nitrogen is an effective supercritical fluid for extraction or drying processes due to its small molecular size, high density in the near-liquid supercritical regime, and chemical inertness. We present a supercritical nitrogen drying protocol for the purification treatment of reactive, porous materials.
FAQs
Constitutive equations determine how an Advanced Material Model translates changes in stress, strain, temperature, damage, or time into predicted material behavior. Their value is that they connect interacting variables rather than treating each load case as an isolated empirical observation. In finite element analysis, this relationship lets engineers evaluate responses under changing conditions and examine deformation or failure more consistently.
Nonlinear, anisotropic, and history-dependent behavior require different modeling considerations. Nonlinearity means the response may not scale simply with the applied load; anisotropy accounts for direction-dependent behavior; and history dependence makes the current state depend on earlier loading or environmental conditions. Including these effects can make simulations more representative of realistic operation than simple empirical rules.
Material parameters control how the equations represent a particular material and its response. Engineers use them alongside variables such as stress, strain, temperature, damage, and time to describe conditions that may evolve during operation. Choosing parameters that reflect the intended material and environment is central to obtaining useful predictions of deformation, failure, fatigue, or other simulated outcomes.
Coupling material behavior with temperature, damage, and time allows a model to represent changes that occur as operating conditions evolve. When these variables interact with stress and strain, the simulation can address more than isolated mechanical loading and can support analysis of multiphysics interactions. This broader representation is useful when component performance depends on both material state and environment.
A typical engineering workflow begins by selecting constitutive equations and material parameters that represent the behavior of interest. The model is then incorporated into finite element analysis, where loads and environmental conditions are represented numerically. Engineers examine predicted deformation, failure, fatigue, or multiphysics responses, using the results to assess performance under realistic operating conditions and guide design decisions.
Advanced Material Models are valuable when engineers need predictions beyond what simple empirical rules can provide, particularly for realistic loading or environmental conditions. Their results can support safer component and structural decisions, reduce reliance on costly physical testing, and guide development of high-performance materials. They therefore connect computational analysis with both design evaluation and materials research.
