Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Reactor on molten salts and fast neutrons 29.11.2021

TerraPower, which is heavily funded by Bill Gates, is also developing the Molten Chloride Experimental Reactor (MCRE) along with the Natrium reactor project. Like the Natrium project, the MCRE reactor is powered by the radioactive decay of the fuel by absorbing fast neutrons, but in the case of the MCRE, the molten salt serves as both a coolant and a means of supplying fuel to the reactor. This is a winning combination.

The construction and operation of the MCRE reactor will be carried out by the Southern Company, a major operator of a range of generating facilities in the United States. The Southern Company recently signed an agreement with the US Department of Energy to design, build and operate the Molten Chloride Experimental Reactor (MCRE) at the Idaho National Laboratory (INL) site. In addition to TerraPower, Southern Company and INL, Core Power, Orano Federal Services, Electric Power Research Institute and 3M Company are participating in the project.

The US Department of Energy has allocated tens of millions of dollars for this project for several years in a row. TerraPower is also developing a marine version of the MCRE, the m-MSR, likely for the US Navy. The money is part of a five-year program that aims to provide information for the design, licensing and operation of a demonstration reactor.

TerraPower's MCFR technology uses molten salt as a coolant and fuel feed to the reactor, enabling so-called fast spectrum, which the company says makes the fission reaction more efficient. The plant operates at higher temperatures than conventional reactors, generates electricity more efficiently, and also offers the potential to use process heat and store (storage) heat for later generation.
