Material uses live cyanobacteria to neutralize waterborne pollutants (06/09/2023)
We often hear of cyanobacteria as being the cause of toxic blue-green algae blooms in lakes and rivers. Soon, however, a 3D-printed material that incorporates the microbes could be used to help purify polluted water – and after the bacteria are finished, they'll kill themselves.
Oil-Capturing Technology Offers 10x Improvement Cleaning Up Hazardous Spills (06/09/2023)
To combat the extreme environmental toll of major oil
spills, researchers at The University of Texas at Austin have created a
technology that could significantly improve cleanup capabilities compared with
current methods.
Linking two solar technologies is a win-win for efficiency and stability (05/09/2023)
While conventional silicon-based
solar cells have had an unmistakable impact on the buildout of renewable energy
resources around the world, additional performance improvements have become
increasingly difficult to make as the devices approach their practical
efficiency limits. This constraint has prompted scientists to seek out new
technologies that can be combined with silicon cells to unlock higher
efficiencies.
Living model of brain reveals how human neurons work together to process information (05/09/2023)
A paper published in Nature
Communications shows that when neurons are given information about the
changing world around them (task-related sensory input) it changes how they
behave, putting them on edge so that tiny inputs can then set off
"avalanches" of brain activity, supporting a theory known as the
critical brain hypothesis.
Discovery puts a magnetic spin on neuromorphic computing (05/09/2023)
The word "fractals" might
inspire images of psychedelic colors spiraling into infinity in a computer
animation. An invisible, but powerful and useful, version of this phenomenon
exists in the realm of dynamic magnetic fractal networks.
Using water to reduce carbon dioxide emissions (05/09/2023)
Water could play a crucial role in reducing global carbon dioxide (CO2) emissions, according to Johns Hopkins engineers.
14 Vietnamese scientists named in world rankings by research.com (02/09/2023)
The website Research.com on September 1 announced its rankings of world scientists with excellent achievements in scientific publications in 2023, in which there are 14 Vietnamese.
A new protocol to reliably demonstrate quantum computational advantage (02/09/2023)
Quantum computers, devices that
perform computations by exploiting quantum mechanical phenomena, have the potential
to outperform classical computers on some tasks and optimization problems. In
recent years, research teams at both academic institutions and IT companies
have been trying to realize this predicted better performance for specific
problems, which is broadly known as "quantum advantage."
Realizing ultrafast imaging from 2D to quasi 3D (02/09/2023)
Scientists at Beijing Institute
of Technology have developed an ultra-fast quasi-three-dimensional technology,
overcoming the shortcomings of missing information in two-dimensional images
and incomplete features, allowing for the analysis of three-dimensional
characteristics of ultra-fast processes.
A particular way of creating quantum entanglement may improve accuracy of advanced quantum sensors (01/09/2023)
Metrological institutions around
the world administer our time using atomic clocks based on the natural
oscillations of atoms. These clocks, pivotal for applications like satellite
navigation or data transfer, have recently been improved by using ever higher
oscillation frequencies in optical atomic clocks.
