Explosive reagent

31.05.2011

A substance has been created that quickly changes color when it comes into contact with vapors of liquid explosives. Using hydrogen peroxide, you can make an explosive liquid at home in the kitchen, which will serve as a detonator for a homemade bomb.

In 2001, they tried to carry a bomb with such a fuse on board the aircraft, after which they began to check the contents of tubes, bottles and vials from all passengers, or even take them away altogether. That's why Dr. Allen Arblet, a chemist at the University of Oklahoma, specifically targeted peroxides.

He made a preparation containing nanoparticles of the molybdenum compound. In the initial state, the preparation is blue, and after interaction with peroxide vapor it becomes yellow or colorless. The sensitivity of the Arblet reagent is very high - in just 30 seconds it recognizes peroxide at a concentration of 50 parts per million. Moreover, the drug can also neutralize explosives - if it is sprayed onto a dangerous object until the color stops changing.

The creator of the reagent believes that the invention will find application not only in the fight against terrorism, but also in chemical laboratories - the addition to solvents will help to avoid the accumulation of explosive peroxides. Confident of the success, Arblet and his colleagues have already set up a reagent company and hope to see their blue paint on the walls of airport checkpoints in the coming year. Maybe then respectable passengers will have fewer problems.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

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 ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

An ocean could be hiding under the surface of Pluto's moon 22.02.2016

Specialists from the US National Aeronautics and Space Administration (NASA) believe that in the distant past, a vast subsurface ocean could have existed on Charon.

Charon is the largest known moon of Pluto. This moon was discovered in 1978. The diameter of Charon, according to modern estimates, is 1205 km - a little more than half the diameter of Pluto itself.

The possible existence in antiquity of the ocean under the surface of Charon is evidenced by the images transmitted to Earth by the automatic station New Horizons ("New Horizons"). The fact is that the satellite of Pluto is dotted with crevices, cliffs and ledges. So, not far from the equatorial zone of Charon there is a strip of canyons with a length of about 1800 km and a depth of up to 7,5 km. Due to the features of the relief in this area, it seems that the outer layers of the satellite were stretched and torn as a result of some kind of impact.

Scientists believe that in ancient times the temperature of Charon was high enough that an ocean of liquid water could exist under the surface. However, as the satellite cooled, the water froze, expanding along the way, which led to the formation of canyons.
