The novel fuel cell electrode has a porous and mechanically stable layer due to its production via selective laser melting and therefore comprises a high power density at a low power-to-weight ratio and can be used at a wide range of temperatures.
Scientists at Aalen University have developed a device which allows the rotation of samples. It can be used in conjunction with a range of microscopy methods, including single-plane illumination microscopy (SPIM) and laser scanning microscopy. This enables scientists for the first time to observe 3D samples from all sides using conventional microscopes. Since the sample is kept in a fixed position relative to the microscope, the method opens up new possibilities for the 3D reconstruction of samples, for example in combination with single plane imaging.
In commercially available piezoelectric nebulizers, the properties of the generated aerosols are largely predefined by the design of the nebulizer device. Particle size distribution and output can hardly be varied and it is often only inadequately possible to generate a sufficiently large fraction of fine particles for pulmonary deposition.
Aerodynamic properties and the mass flow of the generated aerosols can however be influenced without changing the piezoelectric nebulizer device by an addition of modified polymers.
Objective of this innovation is a coating of nebulizer membranes that is aimed at an improvement of the aerosol physical parameters of the aerosol which is generated. This is achieved by reducing the hole diameter of the coated membrane used.
This innovation concerns biocompatible polymeric nano-, meso- and micro-polymer particles which are able to bind pathogenic proteins that penetrate into the lining layer of the lung. These particles can be used for the prevention and treatment of lung diseases which are associated with an increased lung surface tension and a damage of the pulmonary surfactant.
The study showed that artificial light has a considerable influence on the activity times of blackbirds in the city and therefore on their natural cycles,…
