Teslaphoresis at the nanoscale

19.04.2016

Like many other inventions of Nikola Tesla, the coil (transformer) named after him was used by scientists for various purposes, but in our time only one application was widely known - cognitive and aesthetic due to the formation of beautiful gas discharges. However, scientists at Rice University in Houston (Texas, USA) managed to find quite a practical use for the coil.

Using the powerful electric field of a Tesla transformer, the scientists made carbon tubes autonomously form an electrical circuit connecting two LEDs, and then used the energy from the same field to light the LEDs. Scientists called their method "Teslaphoresis" by analogy with electrophoresis, which in a broad, and not purely therapeutic sense, involves the movement of particles remotely under the influence of an electric field.

Teslaphoresis uses an antenna attached to a Tesla coil that broadcasts a high-voltage electric field into open space. In a process that scientists say resembles a tractor beam, they remotely oscillated positive and negative charges on each of the many thousands of single-walled carbon tubes. To do this, the researchers placed the tubes in an electric field, which then caused the tubes to connect into a circuit that turned out to be long enough to be used on a macro scale - the longest "wire" was 15 cm long.

In experiments, scientists managed to form chains of nanotubes at a distance of several tens of centimeters from a modified Tesla coil, which produces a very strong field. Moreover, there was enough energy to ensure the glow of the LEDs. According to the authors of the experiment, the ability of carbon nanotubes to self-assemble into long parallel formations can be further used to control self-assembly both on the micro- and macroscales.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

Xiaomi MIJIA Smart Audio Glasses 19.04.2023

Xiaomi has come up with an unusual solution for Bluetooth audio playback. MIJIA Smart Audio Glasses are equipped with noise reduction and double protection against unwanted eavesdropping. The speakers are open - you can hear the surrounding sound at the same time. The company promises up to 22 hours of battery life for the device.

The glasses have double protection against sound leakage, noise reduction during a call, support surround sound and connect two devices. The noise reduction algorithm uses artificial intelligence when working with both microphones. AI amplifies the sound on a call, restores the timbre, and provides a stable and clear voice communication.

The glasses are very light - their weight is only 38,1 g, the case is protected from moisture and dust according to the IP54 standard. Touch control panels are located on both sides, have a size of 30 mm and support long pressing. The search for glasses and tracking the donning works. The battery provides up to 7 hours of continuous talk time, 10 hours of continuous music playback and up to 22 hours of battery life.

MIJIA Smart Audio Glasses will be available for crowdfunding from April 12 to 26, and can be pre-ordered for 799 yuan (about $116). There are 5 frame options to choose from.
