Construction of dual heterogeneous interface between zigzag-like Mo-MXene nanofibers and small CoNi@NC nanoparticles

Physorg.com - 26 марта, 2024 - 23:23
Two-dimensional transition metal carbides (MXene) possess attractive conductivity and abundant surface functional groups, providing immense potential in the field of electromagnetic wave (EMW) absorption. However, high conductivity and spontaneous aggregation of MXene suffer from limited EMW response. Inspired by dielectric–magnetic synergy effect, the strategy of decorating MXene with magnetic elements is expected to solve this challenge.

A nanoscale look at how shells and coral form reveals that biomineralization is more complex than imagined

Physorg.com - 26 марта, 2024 - 20:06
Exactly how does coral make its skeleton, a sea urchin grow a spine, or an abalone form the mother-of-pearl in its shell? A new study at the Advanced Light Source at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) revealed that this process of biomineralization, which sea creatures use to lock carbon away in their bodies, is more complex and diverse than previously thought.

DNA nanotube rings: Research team develops important building block for artificial cells

Physorg.com - 25 марта, 2024 - 20:03
During cell division, a ring forms around the cell equator, which contracts to divide the cell into two daughter cells. Together with researchers from Heidelberg, Dresden, Tübingen and Harvard, Professor Jan Kierfeld and Lukas Weise from the Department of Physics at TU Dortmund University have succeeded for the first time in synthesizing such a contractile ring with the help of DNA nanotechnology and uncovering its contraction mechanism. The results have been published in Nature Communications.

Catalysis breakthrough yields self-cleaning wall paint that breaks down air pollutants when exposed to sunlight

Physorg.com - 25 марта, 2024 - 19:36
Typically, beautiful white wall paint does not stay beautiful and white forever. Often, substances from the air accumulate on its surface. This can be a desired effect because it makes the air cleaner for a while—but over time, the color changes and needs to be renewed.
