Carbon nanotubes developed for super efficient desalination
Posted by Quinn Sena in categories: nanotechnology, sustainability
Membrane separations have become critical to human existence, with no better example than water purification. As water scarcity becomes more common and communities start running out of cheap available water, they need to supplement their supplies with desalinated water from seawater and brackish water sources.
Lawrence Livermore National Laboratory (LLNL) researchers have created carbon nanotube (CNT) pores that are so efficient at removing salt from water that they are comparable to commercial desalination membranes. These tiny pores are just 0.8 nanometers (nm) in diameter. In comparison, a human hair is 60,000 nm across. The research appears on the cover of the Sept. 18 issue of the journal Science Advances.
The dominant technology for removing salt from water, reverse osmosis, uses thin-film composite (TFC) membranes to separate water from the ions present in saline feed streams. However, some fundamental performance issues remain. For example, TFC membranes are constrained by the permeability-selectivity trade-offs and often have insufficient rejection of some ions and trace micropollutants, requiring additional purification stages that increase the energy and cost.

Water purifier sucks salt out of water like a mangrove tree

A new device that takes salt out of water gets its inspiration from the subtropical mangrove tree.

In addition to offering a better understanding of plants’ plumbing systems, it could lead to new desalination technologies, the researchers say.

NASA Found Another Way Into Nuclear Fusion
Posted by Quinn Sena in categories: nuclear energy, particle physics, space
O,.o.
NASA has unlocked nuclear fusion on a tiny scale, with a phenomenon called lattice confinement fusion that takes place in the narrow channels between atoms. In the reaction, the common nuclear fuel deuterium gets trapped in the “empty” atomic space in a solid metal. What results is a Goldilocks effect that’s neither supercooled nor superheated, but where atoms reach fusion-level energy.

Tesla’s Future Battery Might Use Diamonds, Could Transform The Industry
Posted by Omuterema Akhahenda in categories: Elon Musk, nanotechnology
How about a battery that can generate enough electricity to power an EV for years without ever needing to be recharged?
Will Elon Musk and crew will be unveiling a nano-diamond-battery on Tuesday? It’s fun to imagine the limitless possibilities. But, it really could happen.

The Universal Mind Revealed as a Multi-Layered Quantum Neural Network
Posted by Alex Vikoulov in categories: mathematics, particle physics, quantum physics, robotics/AI
In the sixties of the previous century, the science of Cybernetics emerged, which its founder Norbert Wiener defined as “the scientific study of control and communication in the animal and the machine.” Whereas the cyberneticists perhaps saw everything in the organic world too much as a machine type of regulatory network, the paradigm swapped to its mirror image, wherein everything in the natural world became seen as an organic neural network. Indeed, self-regulating networks appear to be ubiquitous: From the subatomic organization of atoms to the atomic organization of molecules, macromolecules, cells and organisms, everywhere the equivalent of neural networks appears to be present.
