It is a Russian-German dipole beamline, part of the Russian-German Laboratory at BESSY II. It covers a soft X-ray photon energy range up to 1200 eV. It ends with a fixed experimental station RGL-PES that offers a multi-technique approach for the investigation of the electronic, chemical and structural properties of materials: X-ray photoemission spectroscopy and X-ray absorption in all possible modes (fluorescence yield, total and partial electron yields).Read More →

An Artwork reminds on the scientist who cofounded the Russian German Collaboration at BESSY II It seems, she has just calculated something, a hand lies on the paper, next to the pen. The other one supports the chin, relaxed and curious, she looks at the viewer. The Russian physicist Vera Adamchuk is immortalized in the bronze relief attached to a column in the BESSY II hall. The column stands in front of the dipole beam line of the Russian-German laboratory. Vera Adamchuk is regarded as a pioneer of German-Russian cooperation in the field of synchrotron radiation. She co-founded the Russian-German laboratory at BESSY II inRead More →

The beamline is called PM4. As a dipole beamline, it provides a moderate photon flux over a wide range of photon energies, in our case in the vacuum ultraviolet/soft X-ray regime. It serves the fixed end-station called LowDosePES. As the name suggests, its specialty is photoemission spectroscopy (PES) at low X-ray dose. Read More →

OK, here we are. My name is Vlad. I’m a summer student from Moscow and the author of this note concurrently.  If you are reading this post, I bet 90% you was interested in the title. But I suggest to talk about it a bit later.  Just for the beginning , everything you need to know about solar cells is that they consist of silicon. The second point is that the first one was a lie. In fact, not only silicon is used in solar cells. Since the moment people decided to use solar cells as a real source of energy, scientists have been workingRead More →

I want you to imagine the sun with wrong rays that cause a lot of problems. We cannot enjoy the sunshine. We want to do something to replace the wrong rays with the right ones. In my scientific project, the sun is germanium (Ge) nanoparticles, and the rays are a ligand. The wrong ligand is oleylamine. Oleylamine is an organic molecule containing an amino group and a long hydrocarbon chain. It would be perfect to remove oleylamine from the particles and attach another molecule. Speaking in scientific language, I am trying to do ligand exchange on germanium nanoparticles surface. Why germanium? Firstly, Ge is anRead More →

When I was a child, I asked parents that “why is flying bird?” “Why is the sky blue?” and they said this could be explained by science. Science is a tool used for understanding the world around us. The more I understood that the more I was enjoyable, and this drew my attention to study in science. While I was studying science, I was working to seek for truth, based on observation, knowledge and experience. Luckily, I have gotten an oppotunity as a participant in the the summer student programme 2019 at the HZB. This program provides a great occasion to many students at myRead More →

A synchrotron light source is a source of electromagnetic radiation produced by a storage ring, for scientific and technical purposes. The major applications of synchrotron light are in condensed matter physics, materials science, biology and medicine. Metrology Light Source(MLS) is a minor light source near BESSY II. It like a small replica of BESSY. Accelerator and us, just like patient and doctors. We need a stethoscope to know the situation of the patient. My work here is to develop a tool to monitor and adjust the chromacity of this storage ring. The chromacity here is not for the synchrotron light, it is a parameter toRead More →

Sunlight is a huge source of energy. However, it is not available 24/7. But, solar energy can be used to split water. Water splitting is the decomposition of water into oxygen and hydrogen gas due to the passage of an electric current induced by two electrodes in a conductive solution. This hydrogen can be stored or transported and be used later. Scientists at the Institute for Solar Fuels work on a way to split water efficiently by studing different type of electrodes. Usually, a high photocurrent during water splitting means a high production of hydrogen. When I arrived for my internship at HZB in Wannsee,Read More →

Let’s spray and create samples ! In the institute of Solar Fuel, the main research is to produce hydrogen from sunlight and water. Hydrogen can be used to easily store energy and also directly for transportation. But how can we produce it? Only from the sunlight, a metal oxide semiconductor and water. Photons from sunlight will be absorbed by the metal oxide, and this will generate electrons and holes which oxidize or reduce water. The reaction between the electron and hole and the electrolyte allows to separate water in oxygen and hydrogen. Let’s see how we make this metal Oxide!

From a speaking Barbie doll to ISRO’s space rocket, everything in the current world runs with transistors as a very basic element in it. It is hard to define the world without considering the evolution of transistor technology. From a room-sized transistor, we have come to an era where transistors are so small that we can’t even see them with our naked eyes. But everything comes with an expiry date on it, we cant scale the size of transistor down anymore, the current time might be an end to transistor technology and a beginning for memristor technology or resistive random access memory. The devices thatRead More →
