Scientists explore the strategies of defects and nanostructure fabrication for promoting piezocatalytic activity
As an important chemical raw material, hydrogen peroxide (H2O2) is widely applied in various aspects of industry and life. The industrial anthraquinone method for H2O2 production has the serious flaws, such as high pollution and energy consumption. By using ubiquitous mechanical energy, piezocatalytic H2O2 evolution has been proven as a promising strategy, but its progress is hindered by unsatisfied energy conversion efficiency.

Atom-by-atom: Imaging structural transformations in 2D materials
Silicon-based electronics are approaching their physical limitations and new materials are needed to keep up with current technological demands. Two-dimensional (2D) materials have a rich array of properties, including superconductivity and magnetism, and are promising candidates for use in electronic systems, such as transistors. However, precisely controlling the properties of these materials is extraordinarily difficult.

Two-dimensional nanomaterial sets expansion record
It is a common hack to stretch a balloon out to make it easier to inflate. When the balloon stretches, the width crosswise shrinks to the size of a string. Noah Stocek, a Ph.D. student collaborating with Western physicist Giovanni Fanchini, has developed a new nanomaterial that demonstrates the opposite of this phenomenon.

Study finds iron-rich enamel protects, but doesn't color, rodents' orange-brown incisors
Chattering squirrels, charming coypus, and tail-slapping beavers—along with some other rodents—have orange-brown front teeth. Researchers have published high-resolution images of rodent incisors in ACS Nano, providing an atomic-level view of the teeth's ingenious enamel and its coating. They discovered tiny pockets of iron-rich materials in the enamel that form a protective shield for the teeth but, importantly, don't contribute to the orange-brown hue—new insights that could improve human dentistry.
