Remote fingerprint scanning

29.03.2015

Japanese scientists have developed a device that allows you to remotely remove fingerprints left by an attacker from a surface. This procedure will require an apparatus called a forensic hyperspectral projector, capable of non-contact scanning of prints from any surface.

Researchers from the Japanese Police Research Department, together with engineers from Waseda University, have created a projector that uses a green laser to recognize a fingerprint. The system, due to the beam reflected from the object under study, analyzes the image for the presence of protein and fat particles that remain after contact with the object.

The announced technology allows you to recognize a fingerprint even if the touches on the object were repeated, as a result of which the skin patterns overlapped each other. In this case, the accuracy of the determination is approximately 70%. Previously, such a method of analysis was completely inaccessible to criminologists.

Japanese engineers are confident in the prospects of the presented solution and hope that the system under consideration, which is based on the principle of probing our planet, will become an indispensable assistant in conducting investigative and search activities. This will speed up the process of catching criminals and facilitate examinations at the crime scene. It is also assumed that the technology of remote scanning of prints using a green laser will read the information necessary for a DNA test.

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, ... >>

Laser using the effect of superconductivity 08.02.2018

In Silicon Valley, a place known as the home of all the latest high technology and innovation, construction has begun on a new X-ray laser that is 3 miles (4,8 kilometers) long and uses a mass of superconducting components. This laser is being built at the Fermi National Laboratory's SLAC National Linear Accelerator Laboratory, where the first cryogenic section has just been delivered.

The 12.2 meter (40 ft) sections, called cryomodules, are the "building blocks" of the future LCLS-II laser, which will replace the existing Linac Coherent Light Source X-ray free electron laser (LCLS). The modules have a series of cryogenic units made of niobium. These knots will form electric fields of special shape and great strength, which will accelerate the electrons to almost the speed of light. The LCLS-II laser will produce pulses 10 times brighter than those produced by the LCLS laser. In this case, the pulse repetition rate will be a million times per second.

Half of the new laser's cryomodules will be made at Fermi National Laboratory and the other half at the Thomas Jefferson National Accelerator Center in Virginia. Initially, each of the created modules will be tested individually at the place of its assembly, after which it will be sent to Silicon Valley. These modules will be installed in the tunnel formerly occupied by the SLAC laser equipment, which is 2 miles long and 10 meters below the ground.

Thanks to the amazing performance of the new laser, scientists will be able to study complex materials and processes with unprecedented resolution. The light from the new laser will make it possible to see rare and transient chemical phenomena, study the work of molecules of biological origin, look into the strange world of quantum mechanics and measure the motion parameters of individual components of molecules and even atoms.
