Disordered structures offer new mechanisms for forming photonic bandgaps and unprecedented freedom in functional-defect designs. To circumvent the computational challenges of disordered systems, we construct modular macroscopic samples of the new class of PBG materials and use microwaves to characterize their scale-invariant photonic properties, in an easy and inexpensive manner.

Source: Vy M. Dong and Diane Le, Department of Chemistry, University of California, Irvine, CA Merrifield's solid-phase synthesis is a Nobel Prize winning invention where a reactant molecule is bound on a solid support and undergoes successive chemical reactions to form a desired compound. When the molecules are bound to a solid support, excess reagents and byproducts can be removed by washing away the impurities, while the target compound remains bound to the resin. Specifically, we will...

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds. To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...
FAQs
Atomic bonding determines how strongly particles interact and how readily they can move relative to one another. These interactions contribute to measurable properties such as stiffness, strength, hardness, conductivity, and fracture resistance. Engineers therefore consider bonding when predicting how a material will respond to loads, energy transfer, or damage during design and service.
The arrangement of particles creates structural features that influence material behavior. Crystal and amorphous structures organize particles differently, while defects introduce irregularities into an otherwise organized structure. Together, these characteristics help explain why materials with different internal structures can show different stiffness, strength, conductivity, or resistance to fracture, even when their compositions are related.
Microstructure connects a material’s internal organization with its engineering performance. It reflects features associated with composition, structure, and defects, which can alter how particles interact and respond to external conditions. By controlling or modifying microstructure through processing, engineers can adjust properties and improve suitability for structures, machines, electronics, or energy systems.
A material’s performance depends not only on its composition and internal structure but also on the conditions imposed during use. External conditions can change how the material responds mechanically or thermally, affecting properties such as strength, stiffness, conductivity, and fracture resistance. Evaluating these influences supports safer designs and helps extend service life.
A typical evaluation considers composition and processing before measuring mechanical or thermal behavior. Engineers use testing to determine relevant properties, then relate those results to the material’s structure and intended function. This workflow provides evidence for comparing candidates, identifying performance limitations, and selecting or modifying materials for a specific engineering application.
Selection begins by matching required performance with properties such as stiffness, strength, hardness, conductivity, and fracture resistance. Engineers also consider how composition, processing, microstructure, and external conditions affect service behavior. Metals, ceramics, polymers, composites, and other advanced materials can therefore be chosen or modified according to the demands of the target system.
