Paris - Japan, a historical tapestry on its journey from the Louvre to an exhibition in Osaka: the AirCorr corrosion logger monitors the air quality surrounding the tapestry. The air humidity fluctuates minimally; the temperature is also fine. However, upon opening the transport box and exhibiting the tapestry in Osaka, the corrosivity increases tremendously.
The AirCorr corrosion logger registers the changes in real time. The data can be read via a wireless interface and transport procedures or the exhibition surroundings can be adjusted. Conventional sensor devices often measure only air humidity and temperature, and, therefore, would not have detected the increased air corrosivity, risking irrevocable damage to the cultural object.
A team of European researchers, museum experts and industry representatives developed the transportable and user-friendly real-time measuring device AirCorr in order to control the impact of corrosive atmospheres, especially on objects of importance to cultural heritage. The plug-in sensor units can be exchanged easily and, hence, can be used to monitor and protect various metallic objects. Important conclusions about the corrosiveness of the ambient air can also be drawn for non-metallic objects.
The loggers can be mounted almost everywhere since they are battery-driven and consume little power. Currently, the devices are being tested in several European museums and exhibitions. Furthermore, the user-friendliness of the logger software is being improved by including existing standards and recommendations, which allow the user to draw straightforward conclusions from the measured data.The concept of the measuring device is simple and yet highly effective: the sensor is comprised of a thin metal layer (copper, silver, lead, iron, zinc, tin, bronze, or brass), which is deposited on an insulating substrate (made of ceramic or polymer). Corrosion of the metal layer causes an increase in its electrical resistance, which is recorded and can be used to calculate the degree of corrosion. A part of the sensor is protected against corrosion by an organic coating and serves as a reference to compensate

Beyond the limits of conventional electronics: stable organic molecular nanowires
24.05.2018 | Tokyo Institute of Technology
The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
