The fastest on/off switch and most precise position control in the world

Posted on by Haptic

How do you turn on and off an ultra-small component in advanced technologies? You need an actuator, a device that transmits an input such as electricity into physical motion. However, actuators in small-scale technologies to date have critical limitations. For example, if it’s difficult to integrate the actuator into semiconductor electronics, real-world applications of the Read more about The fastest on/off switch and most precise position control in the world[…]

How fast is our energy brain

Posted on by Haptic

Researchers from the Netherlands Institute for Neuroscience (NIN) used a new technique to show how electrical impulses are traveling with high speed in the brain. It appears that myelin, the sheath around neurons, creates a coaxial cable producing multiple waves of electrical potentials traveling in a more complicated manner than was envisioned earlier. These findings Read more about How fast is our energy brain[…]

A new portable spectrometer use a smartphone camera to acquire data

Posted on by Haptic

Spectral images, which contain more color information than is obtainable with a typical camera, reveal characteristics of tissue and other biological samples that can’t be seen by the naked eye. A new smartphone-compatible device that is held like a pencil could make it practical to acquire spectral images of everyday objects and may eventually be Read more about A new portable spectrometer use a smartphone camera to acquire data[…]

A new creation of high-capacity hydrogen storage materials

Posted on by Haptic

Sometimes, you have to go small to win big. That is the approach a multilab, interdisciplinary team took in using nanoparticles and a novel nanoconfinement system to develop a method to change hydrogen storage properties. This discovery could enable the creation of high-capacity hydrogen storage materials capable of quick refueling, improving the performance of emerging Read more about A new creation of high-capacity hydrogen storage materials[…]

Quantum dots with impermeable shell: A powerful tool for nanoengineering

Posted on by Haptic

Depending on their applications, quantum dots need to be tailored in terms of their structure and properties. Chemists from Warsaw have shown that quantum dots obtained by their novel method can be successfully functionalized with modern click chemistry. This achievement is of interest not only due to the numerous potential applications, but also because in hitherto experiments copper compounds Read more about Quantum dots with impermeable shell: A powerful tool for nanoengineering[…]

Terahertz technology reaches industrial maturity

Posted on by Haptic

Terahertz is a new technology in which nondestructive testing of components and surfaces is possible. Until now, these devices and, in particular, the sensor heads have been expensive and unwieldy. Researchers at Fraunhofer have now succeeded in making sensor heads more compact and, thus, cheaper, which facilitates their handling considerably. First prototypes are already being Read more about Terahertz technology reaches industrial maturity[…]
