2D material in three dimensions

The carbon material graphene has no well-defined thickness; it merely consists of one single layer of atoms. It is therefore often referred to as a "two-dimensional material." Trying to make a three-dimensional structure ...

SARS-CoV-2 uses sugars to invade human cells

Sugars found on the surface of human cells influence COVID-19 infection, according to a University of Alberta-led study that is one of the first to observe this relationship and suggests that cells in the brain might be particularly ...

Centriole instability might contribute to some cases of microcephaly

Centrioles are cylindrical structures involved in the generation of microtubules—fibers inside of cells that form a network to provide structure and shape to cells and to mediate transport processes. In addition, centriole ...

3D ordered channel enhances electrocatalysis

A team led by Prof. YU Shuhong and Prof. HOU Zhonghuai from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences developed a theory-guided microchemical engineering (MCE) approach to ...

Obtaining metal surfaces with ultralow reflectivity

To fabricate micro/nano structures on metal surfaces, various technologies have been proposed, including chemical etching, mechanical grooving, reactive ion etching, and long-pulse laser processing.
