Apr 22, 2022 (Nanowerk News) Nucleic acids analysis is mainly used in pathogen detection, genetic disease identification and early cancer diagnosis. For example, quantitative analysis of circulating tumor DNA (ctDNA), a free DNA fragment derived from malignant cells which carries tumor specific sequence changes, can help obtain abundant information about...
The deformation of the hydrogel is used to measure the negative pressure of water
Apr 22, 2022 (Nanowerk News) Water, unexpectedly, has the potential to withstand a massive stretching force or tension due to its internal cohesive force. Under extreme tension, the hydrostatic pressure of the water would display as absolute negative. The comprehension of such a unique thermodynamic non-equilibrium state in the phase...

Employing melt polymerization to fabricate robust covalent organic framework foams
Apr 22, 2022 (Nanowerk News) Adsorption-based (e.g., gas or liquid molecules) separation technologies have shown unique economic and environmental advantages in specific applications. In industrial applications, ideal high-efficiency adsorbents require not only high adsorption capacity/selectivity, but also good machinability, cycling, and mechanical stability. Thus, it is necessary to assemble the...
A roadmap for deepening understanding of a puzzling universal process
Apr 22, 2022 (Nanowerk News) A puzzling process called magnetic reconnection triggers explosive phenomena throughout the universe, creating solar flares and space storms that can take down mobile phone service and electrical power grids. Now scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have detailed...
