Most of the electronic devices we use every day, from smartphones to solar panels, depend on electrons moving smoothly through crystal structures. In recent years, however, researchers have discovered that stacking extremely thin materials in carefully chosen ways can produce completely new types of behavior that never appear in ordinary bulk materials. One of the […]

Carbon is one of the most versatile elements in the periodic table. Beyond the familiar forms of graphite and diamond lies a rich family of carbon structures with surprising and useful properties. Among these, graphene, a single two-dimensional (2D) allotrope consisting in a layer of carbon atoms arranged in a perfect hexagonal lattice, has captivated […]

Authors: Mouna Reda, Post doctorate fellow, Department of Civil Engineering, McMaster University and Samir Chidiac, Professor, Civil Engineering, McMaster University As winter approaches, Canada’s roads, bridges, sidewalks and buildings are facing a familiar problem: cracks caused by large temperature swings. These cracks weaken infrastructure and cost millions to repair every year. But what if concrete […]

In the layered kagome metal CsV₃Sb₅, researchers have observed something that, until now, seemed almost impossible: robust quantum interference in the normal, non-superconducting state, persisting over distances of several micrometers. The interference is not the fragile single-particle kind seen in ultra-clean semiconductors at millikelvin temperatures. Instead, it behaves as if the entire stack of kagome […]

Order on a molecular scale is difficult to control. The systems with highest possible order are crystals, formed by long arrays of repeating constituent components in all directions. The most familiar examples of crystals encountered in daily life are table salt and sucrose, the sugar in our kitchens. Every grain of table salt is a […]

Graphene—a single layer of carbon atoms arranged in a honeycomb lattice—has captivated scientists because of its extraordinary electronic and mechanical properties. Its electrons move through the lattice almost as if they were massless, giving graphene exceptionally high electrical conductivity and mobility. However, pristine graphene sheets are not magnetic and their electrons are delocalized across the […]

When we think of faster, cheaper electronics, we usually think “smaller transistors.” But the future is also about stacking—adding new layers of components on top of finished silicon chips. That’s called back‑end‑of‑line (BEOL) integration, and it only works if everything you add can be made at low temperatures (generally below ~400–450 °C), otherwise you damage […]

In polymer science, the classic division is between thermoplastics, which soften and flow when heated, and thermosets, which are permanently cross-linked and keep their shape no matter how hot they get—at least until they burn. In the last decade, researchers have discovered a fascinating new class of materials called vitrimers, which sit between these two […]
