A supramolecule 20 nanometers wide obtained

15.04.2020

Scientists from the University of South Florida (USA) have reached a new milestone in the development of two-dimensional supramolecules - the building blocks that are used in nanotechnology and without which the development of nanomaterials is impossible. They "built" a supramolecule 20 nanometers wide. Previously, the size of such structures did not exceed 10 nanometers.

"Our research team has been able to overcome one of the major supramolecular hurdles by developing a well-defined supramolecular structure that moves in size on a 20-nanometer scale," said Xiaopeng, assistant professor of chemistry at the University of South Florida and leader of the study. "This is, in fact, a world record in this area of chemistry.

Supramolecules are large molecular structures made up of individual molecules. Unlike traditional chemistry, which focuses on covalent bonds between atoms, supramolecular chemistry studies non-covalent interactions between molecules themselves. Often these interactions lead to the self-assembly of molecules, naturally forming complex structures capable of performing various functions.

In this latest study, the team was able to construct a metal-supramolecular hexagonal lattice 20 nanometers wide by combining intra- and intermolecular self-assembly processes. Li says the success of this work will further the understanding of the design principles behind these molecular entities and may one day lead to the development of new materials with as-yet-unknown functions and properties.

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, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Human health miniscanner 26.05.2013

Scientists have developed a device that allows you to quickly scan all the vital parameters of the human body: just hold the device to your forehead for less than 10 seconds.

This device is similar to the tricorder from the science fiction series Star Trek, where a universal scanner made it possible to quickly determine the state of health. The device, called Scout, was developed by the American company Scanadu, based at the Research Center. Ames (NASA) in Mountain View, California. The Scout can track key body functions including temperature, heart rate and rhythm, blood oxygen levels and stress levels.

The Scout scanner is extremely compact - you can carry it in your pocket and quickly check the state of the body at the current time. This will allow you to control the consequences of, for example, physical exertion or quickly identify a life-threatening condition.

Scout developer Walter de Brouwer said that the idea for such a scanner came to his mind when his son was in the hospital and had to watch monitors that control his life parameters. The principle of operation of the Scout is the same as that of stationary medical devices, but unlike the equipment in the clinic, it has much smaller dimensions and can be synchronized with the user's smartphone. This allows you to keep statistics of observations and detect anomalies.

The Scout device can be used everywhere, even at home. This should increase the safety of people, such as those suffering from hypertension. While the technical details of the novelty are unknown, but it can already be reserved on the developer's website.
