Bridge printed on a 3D printer

24.10.2017

In the city of Gemert, located in the south-east of Holland, the world's first concrete bridge built using 800D printing technologies has been opened. The structures of this bridge, which took three months to build, consist of XNUMX layers of concrete. At the same time, not ordinary concrete was used in the construction, but a special high-strength concrete designed specifically for a XNUMXD construction printer.

"The new bridge is quite small. But it was built using a XNUMXD printer, which makes it unique and the only one in the world today" - says Theo Salet (Theo Salet), representative of the Eindhoven University of Technology (Eindhoven University of Technology), - " One of the benefits of building XNUMXD printing technology is that the XNUMXD printer places concrete only where it is needed, resulting in less building materials than the traditional method, where ordinary concrete is poured into pre-prepared wooden forms (forms)."

Before putting the structure into operation, the bridge with 8-meter spans was checked for safety by specialists from the construction company BAM Infra. Despite the fact that the bridge is designed exclusively for cyclists, its design is able to support the weight of a truck loaded with two tons of cargo.

“Now we are looking at the future of building technology,” says Marinus Schimmel, CEO of BAM Infra, “We have been looking for new methods and approaches for a long time that will allow us to build urban infrastructure at a lower cost and with greater speed. In this case, we have strong evidence that XNUMXD printing requires less building materials, fewer human resources, and generates virtually no waste."

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, ... >>

Iron transparent to gamma radiation 28.07.2020

An international group of scientists has learned how to control high-frequency gamma radiation using low-frequency acoustic exposure.

Researchers have found that iron nuclei can be made transparent to the gamma rays they normally absorb. To do this, they use a new method of acoustically induced transparency (AIT). At present, hopes for such transformations are associated with the development of the short-wavelength part of the electromagnetic spectrum - the hard X-ray or soft gamma range.

X-ray and gamma radiation have found many applications in medicine, physics, chemistry, materials science and other sciences. However, most of the coherent optics methods used to control the resonant interaction of optical radiation with matter turn out to be inefficient or unrealizable in the gamma/X-ray range.

Scientists propose to influence the spectral characteristics of the nuclei with the help of acoustic vibration of the medium. In a demonstration experiment at room temperature, a 150-fold increase (from 5,5^10-3 to 0,82) was obtained for the first time in the resonant transmission of single photons with an energy of 25 keV by stainless steel foil 14,4 μm thick without spectral and temporal distortions.

By acting on an absorber containing Fe-57 nuclei using a piezoelectric transducer, it was possible to achieve that the optically dense absorber became transparent to resonant gamma rays. The absorber was attached to a piezoelectric transducer, which vibrated at a certain frequency and amplitude. At an oscillation amplitude corresponding to a modulation index of 2.4, the absorption of photons with an energy of 14,4 keV was suppressed by a factor of 148.
