Plant stress measuring device

08.01.2021

Scientists from the Massachusetts Institute of Technology in Singapore SMART and the Temasek Life Sciences Laboratory have created a portable optical sensor to detect the state of stress in plants.

The Raman device can be attached to plant leaves and is a useful tool in precision farming. The built-in sensor in the invention will allow farmers to diagnose at an early stage nitrogen deficiency in plants, so they spoil prematurely and lose crops.

Scientists have created a device to measure nitrogen levels in plants. But in the end, it turned out that the invention could also identify plant stresses, such as lack of water and minerals, excessive heat and cold. The sensor consists of a 3D printed clamp that is placed around a Raman fiber optic sensor.

The developers are confident that thanks to this, farmers will increase crop yields and reduce the negative impact on the environment. They attribute the environmental friendliness of the device to the reduction of pollution of aquatic ecosystems as a result of nitrogen leakage into groundwater.

SMART, which has joined the production of the device, was formed in 2007 through the joint efforts of the Massachusetts Institute of Technology and the National Research Foundation of Singapore. The scientists of the innovation center are engaged in research in five areas: urban mobility, sustainable technologies in agriculture, electronic systems with low energy consumption, antimicrobial resistance and the production of personalized medicines.

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, ... >>

Thermal sensor interface concept 27.05.2014

Metaio, an augmented reality technology company, announced the development of the Thermal Touch system. This system allows using infrared sensors and smart glasses such as Google Glass to turn any surface into a touch interface, that is, to interact with digital content in any environment.

By combining the infrared image with the image taken by a traditional camera, the system determines the so-called thermal footprint that the user leaves when touching the surface. Adding to this technology augmented reality and computer vision (smart glasses), the user gets a fundamentally new touch interface almost anywhere he wants.

According to the developers, this opens up many possibilities. For example, the user can control the direction of movement of the device by simply touching a normal static map on the wall. According to the inventors, the best user interface for wearable devices has not yet been determined. Developers are actively experimenting with voice navigation, various assistive devices, and projection technologies. To become mass-produced, the technology must be, first of all, convenient, and also operate in the widest range of applications. Perhaps a new invention will be able to meet these requirements.

In the meantime, the developers themselves state with sadness that their technology can become a reality no sooner than in five years. At the same time, up to ten years will pass before thermal sensors become massively integrated into devices.
