Aircraft Engine Coating Could Triple Service Life and Save Fuel

Researchers at University West in Sweden are using nanoparticles in the heat-insulating surface layer that protects aircraft engines from heat. In tests, this increased the service life of the coating by 300%. The hope is that motors with the new layers will be in production within two years. The surface layer is sprayed on top of the metal components. Thanks to this extra layer, the engine is shielded from heat. The temperature can also be raised, which leads to increased efficiency, reduced emissions, and decreased fuel consumption.

Engineers Develop 'Simple' Robotic Swarms

University of Sheffield engineers have developed a way of making hundreds — or even thousands — of tiny robots cluster to carry out tasks. The robots do not require memory or processing power. Each robot uses just one sensor that indicates the presence of another nearby robot. Based on the sensor's findings, the robots will either rotate on the spot, or move around in a circle until one can be seen.Until now, robotic swarms have required complex programming, complicating the development of miniaturized, individual robots. With the programming created by the Sheffield team, however, nanoscale machines are possible.SourceAlso: Learn about a Kinematic Calibration Process for Flight Robotic Arms.

Mini Science Lab Detects Multiple Bio Agents

It can cost hundreds of dollars and days to scan biological materials for important biomarkers that signal diseases such as diabetes or cancer using industry standard equipment. Researchers face enormous time constraints and financial hurdles from having to run these analyses on a regular basis. A Northeastern University professor has developed a single instrument that can do multiple scans at a fraction of the time and cost. That's because it uses considerably less material and ultra-sensitive detection methods to do the same thing. ScanDrop is a portable instrument no bigger than a shoebox that has the capacity to detect a variety of biological specimen. For that reason it will benefit a wide range of users beyond the medical community, including environmental monitoring and basic scientific research. The instrument acts as a miniature science lab, of sorts. It contains a tiny chip, made of polymer or glass, connected to equally tiny tubes. An extremely small-volume liquid sample — whether it's water or a biological fluid such as serum — flows in one of those tubes, through the lab-on-a-chip device, and out the other side. While inside, the sample is exposed to a slug of microscopic beads functionalized to react with the lab test's search parameters. The beads fluoresce when the specific marker or cell in question has been detected; from there, an analysis by ScanDrop can provide the concentration levels of that marker or cell. Because the volumes being tested with ScanDrop are so small, the testing time dwindles to just minutes. This means you could get near-real time measures of a changing sample — be it bacteria levels in a flowing body of water or dynamic insulin levels in the bloodstream of a person with diabetes.

Driving Simulator Helps Engineers Calculate Human Factor

Simulations are an important development tool in the automobile and utility vehicle. The properties of vehicle components, such as how they respond in an accident, their reliability, or their energy efficiency can be investigated using simulations before the first component is manufactured. Researchers developed an interactive driving simulator using RODOS (robot-based driving and operation simulator) with which realistic interaction between human and vehicle can be analyzed.

Moving Magnet Voice Coil Actuators Offer Controllable Movement for High-Duty-Cycle Applications

There are two types of voice coil actuators: moving coil and moving magnet. The materials of construction are similar, since they both use rare earth magnets, steel, copper wire, and basic insulation materials. There is a tendency to want to say one type is better suited for certain applications; however, there are many different sizes and shapes of voice coil actuators, making it difficult to make blanket statements about which type of actuator works better, and where.
