Researchers have developed a new 2D system by depositing platinum atoms on the carbon buffer layer's surface. This chemical sensor can be used to detect toxic gases such as benzene. (Image Credit: Chalmers University of Technology)   Researchers at the Chalmers University of Technology in Sweden and other universities have discovered a way to use one-thin platinum as a chemical sensor. This was achieved by depositing a schematic of platinum atoms on a carbon buffer layer's surface, which i ...
Introduction What is a Measurement Amplifier? Amplifier Circuit Building It Amplifier Noise Frequency Response Building Revision 2.0 Summary   Introduction This blog post discusses an experimental, simple low-noise amplifier project. The amplifier can be used to enlarge tiny signals from sensors, for example for science experiments. Another use-case would be to observe noise on a DC level (for instance power supply noise), or for capturing data for post-proce ...
This new artificial skin can sense changes in pressure, heat, and cold. This artificial skin could lead to more advanced prosthetics and robots. (Image credit: RMIT University)   Though it’s unpleasant, pain is necessary because it helps keep us safe, warning us when our body is in discomfort. Now, researchers have created an artificial skin that can react to pain similar to real human skin. The prototype, created by a team at RMIT University in Melbourne, Australia, mimics the body& ...
To achieve the effect, researchers created a unique Hall-bar-like device of graphene-topological insulator heterostructures. Researchers believe this discovery could be used for applications in spintronic and quantum technologies. (Image credit: CC0 Public Domain)   The spin galvanic effect is a theory many have studied for years for its application to spintronics technology and potential use in the next generation of electronics. Recently, researchers at the Chalmers University of Technol ...
Are we one step closer to the holographic technology found in a galaxy far, far away? (Image credit: Tokyo University)   Remember the scene from Star Wars: A New Hope when Princess Leia used holographic technology to ask Obi-Wan Kenobi for help? That scene is now a reality thanks to a recent breakthrough. Researchers from the Tokyo University of Agriculture and Technology discovered a way to bend light in ways that natural materials can't - using metasurface materials. The result is a true ...
The nano=scaled tweezers could be used to detect pathogens and early stages of diseases such as Alzheimer's. (Image Credit: Justus Ndukaife, Vanderbilt University)   Today's optical tweezers, which use a highly focused laser beam to trap and move micron-scale objects, can't grip anything smaller than a red blood cell. Engineers at Vanderbilt University have developed opto-thermal-electrohydrodynamic tweezers (OTET) that are capable of manipulating DNA molecules and proteins without causing ...
