With its high mechanical resistance and high elastic recuperation qualities, Graphene aerogel is already considered as the lightest material developed in the laboratory nowadays. [2] Aerogel is composed of low-density materials in solid state derived from gel, with its liquid component substituted by ...
3D Printed Graphene Aerogel Offers Highest-Ever Capacitance for a Supercapacitor by Dexter Johnson. IEEE Spectrum, 23 October 2018. Energy storage leap could slash electric car charging times by Adam Vaughan, The Guardian, 26 February 2018. Could fast-charging supercapacitors revolutionize "battery" li...
An asthma attack is anything but a simple event. It begins when environmental factors—allergens—enter the lungs and activate a chain reaction of molecular pathways that set off the development of the disease. Allergens activate immune cells, recruiting them to the lungs and leading some of them...
In crystals, atoms regularly pack into identical unit cells of well-ordered lattices. In glass, however, they sit at random distances from each other, an arrangement that infinitely increases the number of possible configurations. The same atomic chaos is true of a liquid. In fact, atomically, ...
The results were close—but not quite the same. While the data leaned towards the constant, it wasn't strong enough to say whether there is a real discrepancy between the amount of matter measured by the Dark Energy Survey versus thecosmic microwave backgroundresults. That could indicate some...
Using a simple, one-step process, the researchers coated iron-oxide nanoparticles with green-tea compounds called catechins and administered them to mice with cancer. MRIs demonstrated that the novel imaging agents gathered in tumor cells and showed a strong contrast from surrounding non-tumor cells...
Black holes are regions of space wheregravityis so strong that not even light can escape and so isolated black holes are truly dark objects and don't emit any form of radiation. However, black holes that get deformed, because of other black holes or stars crashing into them, are known to...
Practically, infrared spectra show a strong overlap between the Si-O and P-O stretching vibrations at ca. 1000 cm−1. In adsorption experiments where the relative amount of nucleotide is orders of magnitude smaller than the amount of silicate, such an overlap precludes the detection of any ...
