Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Nano-cleaning of frescoes
07.09.2007
About forty years ago, art restorers began to cover ancient frescoes with transparent acrylic varnishes to protect them from air pollution, exposure to light and oxygen.
The solution seemed perfect. However, after some time problems emerged. The polymers closed the microscopic pores through which the wall "breathed" under the fresco. As a result, moisture began to accumulate under the layer of paint, and salts were deposited, destroying the painting.
Two decades later, the lacquer itself began to collapse - turn yellow, wrinkle. The restorers had to wash off the varnish from the frescoes. But conventional organic solvents are dangerous when working with them and, in addition, they do not penetrate well into the micropores of the plaster.
Italian chemists from the University of Florence have created and successfully tested an aqueous emulsion with droplets of organic solvents up to 10 nanometers across for cleaning frescoes. The content of these solvents in the emulsion is less than one percent, but due to the nano-sized droplets, they perfectly penetrate the pores of the plaster. Not only varnish is removed, but also impurities such as soot from church candles and censers.
