Perovskite on optoelectronics
In addition to convert light in electrical energy, the perovskite material also has a great number of applications.
Proba-3, the creator of artificial eclipses
Proba-3 is a technology demonstration mission of European Space Agency (ESA), which will create artificial eclipses to study the Sun.
Perovskite, the new material for solar energy
The perovskite promises to revolutionize the photovoltaic solar energy. Properties and use on solar energy are this post’s subjects.
Crookes radiometer
The Crookes radiometer, or light mill, it’s an experiment which demonstrate motion caused by electromagnetic radiation.
The world’s fastest microscope
At the University of Arizona, in Tucson, it was built a laser microscope, that can capture images in an attosecond.
Metamaterials: what are they?
Metamaterials have artificially created structures, to have properties that no conventional material has.
Solar sail propulsion
The propulsion by solar sail can be an alternative for long space travel. This technology’s operation is this post’s subject.
Antenna for 6G networks
The wireless communication technology 6G is still in development. A recently built antenna prototype can be used on these networks.
Optocoupler with phototransistor
The optocoupler electrically insulates a circuit’s input and output. The operation and some projects are shown in this post.
