Solidification of bulk substances
30.04.2024
There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>
Implanted brain stimulator
30.04.2024
In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>
The perception of time depends on what one is looking at
29.04.2024
Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>
| Random news from the Archive Panasonic DDL Laser
11.02.2020
Panasonic has unveiled the world's brightest and most powerful blue laser. This achievement was made possible by the combination of several technologies - direct diode laser (DDL) technology and wavelength beam combining (WBC) technology, due to which the device outputs a single powerful beam of blue laser light. . Moreover, this technology allows scaling to any level, and by increasing the number of laser light sources, it is possible to increase the power of the output beam to unimaginable values.
A DDL laser is a semiconductor system that emits a highly focused beam of light in a given direction. Unlike other solid-state laser technologies, DDL technology allows for smaller, more efficient devices that produce more output with less energy, and this is the key reason why such lasers are widely used in laser welding, cutting, etc. P.
Panasonic has been working in this direction for a long time. Since 2013, the company has been cooperating with TeraDiode (TDI), which developed WBC technologies, and in 2017, Panasonic simply absorbed TDI, and this made it possible to develop an effective technology for reducing the laser light wavelength in a fairly short time.
Panasonic's new laser operates in a rather narrow range of 400 to 450 nanometers, although conventional blue lasers cover a wider range of 360 to 480 nanometers. And in the output beam of the device, the energy of light emitted by hundreds of DDL lasers is concentrated. At the same time, laser diodes were made in the form of matrices located on separate semiconductor crystals, which also contain all the necessary control electronics.
The new blue laser, according to representatives of Panasonic, is an ideal device for creating micromachining technology for such complex materials as copper, silver, gold, etc., which have high thermal conductivity. The thermal conductivity of these materials requires the use of such an amount of light energy for their processing that not only laser systems generating lower energy and longer wavelength radiation are unable to supply, but also conventional blue laser systems, which lag behind the new system by at least two orders of magnitude in terms of output power.
