Samsung's New LM281D+ Series LEDs

29.04.2018

Samsung has introduced a new budget series of 281W LM0,5D+ LEDs in the popular 2835 package. As the manufacturer positions these LEDs, LM281D+ are designed to achieve the highest level of brightness-to-price ratio.

One of the main distinguishing features of the LM281D+ is the increased maximum operating current up to 200 mA. This makes it possible to solve a wider range of tasks in the field of LED lighting, compared to the previous generation of LEDs in this family, in which the value of the maximum operating current does not exceed 160 mA.

With high efficiency and low cost, Samsung's new LM281D+ LED series is ideal for both office, retail and other commercial and residential applications, as well as for decorative and architectural lighting.

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 ... >>

Drones can smell 05.12.2020

University of Washington engineers connected a live moth's antenna to an electronics suite and used it to point the drone at specific smells. They call the created machine Smellicopter.

"Nature is head and shoulders above our artificial odor sensors. By using the olfactory antenna of a real moth on a Smellicopter drone, we can get the best of both worlds: the sensitivity of a biological organism on a robotic platform that can be controlled," says Melanie Anderson, lead author of the study.

The hollow tubular antenna is borrowed from the tobacco hawk moth (manduca sexta). Small electrodes are inserted into each end of the antenna, which pick up the signal from its receptors. The antenna remains biologically and chemically active for up to four hours after removal, but its shelf life can be extended if the component is refrigerated.

To test the resulting cyborg's sense of smell, the team placed the sensor in a wind tunnel, where it had to compete with a standard artificial smell sensor. Tests have shown that the moth's antenna reacts to the smell of flowers or ethanol much faster than any other sensor.

In the following experiments, the researchers mounted the sensor on a small quadcopter equipped with two plastic fins that allow the car to navigate with the wind and four infrared obstacle detection sensors.

The Smellicopter is powered by an algorithm that mimics the flight of a butterfly. The drone starts flying by drifting to the left for the specified distance. If it doesn't detect a strong enough odor, it changes course and moves to the right. Having detected the smell, the drone flies to its source. If at any time the infrared sensors detect an obstacle within 20cm, the Smellicopter will change direction.

The device can be used to detect explosives or the breath of people stuck under rubble at disaster sites.
