Researcher Wieger Wamelink of Wageningen University showed in model calculations that the carbon sequestration for all forests in The Netherlands may drop to 27 % of its present value. This reduced sequestration is expected as a result of pollution control policy strategies in all countries with present high nitrogen deposition, mainly located in Europe, North America and Asia.
The greenhouse gas carbon dioxide is fixed in wood when a tree is growing. The faster a plant is growing the more carbon dioxide is taken out of the atmosphere. Besides carbon trees need nitrogen to grow. Normally, this nitrogen originates from soil processes. But added nitrogen via air pollution originating from agriculture, industry and transport will stimulate tree growth.
Nitrogen is a nutrient for plant species. However, they all have there specific preference for the amount of nitrogen. Due to excessive nitrogen deposition many rare species are out competed and are threatened to become extinct. To save the threatened species the EU and its member states have a pollution control policy strategy to reduce the nitrogen deposition. Species will then recover, but mainly outside forests, e.g. in grassland and heathland.
To remove the excess nitrogen from natural areas extra frequent management, such as sod cutting, mowing etc, is carried out. This extra management is costly. When the nitrogen deposition drops, savings of over € 40 million per year is possible on management costs, which is approximately one quarter of the amount of money spent on management in The Netherlands.

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...
