Plastic (irreversible) deformation of crystals requires disrupting the crystalline order, which happens through nucleation and motion of topological line defects called dislocations. Interactions between dislocations…

Ni-Zn battery is a rechargeable aqueous battery with high theoretical power density and considerably low cost in addition to being safe and sustainable. Currently, its…

Metal nanoparticles (NPs) supported on metal-oxides play a critical role industrial catalytic processes. The activity and selectivity of NPs used in catalysis depends on their…

Scintillators are used as detector materials for various kinds of ionizing radiation in applications ranging from medical imaging to fundamental physics. Each application has its…

An important microstructural feature of polycrystalline materials is grain size, since grain size and the respective area of grain boundaries affect mechanical and functional properties.…

Hematite is a widely studied material as an anode for water-splitting due to some favorable properties, such as a suitable bandgap, high abundance, and high…

From snowflakes to nanoparticle superlattices, a menagerie of complex structures emerge from simple building blocks attracting each other with Coulombic forces. On the colloidal scale,…

Base-base mispairs are dominant sources for genetic mutations. Each mismatch enforces different DNA conformations, which are dictated by the number, arrangement, and chemical identity of…

Cellulose is a widely used natural polymer synthesized by plants and some bacteria. It was discovered that cellulose has piezoelectric properties. Recent studies showed that…

Calcium manganite (CaMnO3)-based oxides are applied for thermoelectric (TE) energy conversion, and are inexpensive, nontoxic and possess chemical and thermal stability. The major challenge in…
