New cookbook "Science-Food" - download now!
For this cookbook, staff and guest researchers have told us their favorite dishes from their home countries.
People from many different countries work at the Helmholtz-Zentrum Berlin and enrich our atmosphere. For our cookbook, employees and guest researchers from six continents have contributed their favorite recipes.
Home-cooked dishes are a great way to raise a smile. Hospitality is an important part of the tradition in most countries of the world. Eating, talking and laughing together unites people from all nations. In this new edition of the cookbook, you will find a unique collection of international dishes: from Korean appetizers to Mexican main courses and French desserts.
Let yourself be inspired by the culinary journey around the globe.

Green hydrogen: How photoelectrochemical water splitting may become competitive
Sunlight can be used to produce green hydrogen directly from water in photoelectrochemical (PEC) cells. So far, systems based on this "direct approach" have not been energetically competitive. However, the balance changes as soon as some of the hydrogen in such PEC cells is used in-situ for a catalytic hydrogenation reaction, resulting in the co-production of chemicals used in the chemical and pharmaceutical industries. The energy payback time of photoelectrochemical "green" hydrogen production can be reduced dramatically, the study shows.
Superstore MXene: New proton hydration structure determined
MXenes are able to store large amounts of electrical energy like batteries and to charge and discharge rather quickly like a supercapacitor. They combine both talents and thus are a very interesting class of materials for energy storage. The material is structured like a kind of puff pastry, with the MXene layers separated by thin water films. A team at HZB has now investigated how protons migrate in the water films confined between the layers of the material and enable charge transport. Their results have been published in the renowned journal Nature Communications and may accelerate the optimisation of these kinds of energy storage materials.
Maria Skłodowska Curie Postdoctoral Fellowship for Artem Musiienko
Dr. Artem Musiienko has earned a prestigious Maria Skłodowska Curie Postdoctoral Fellowship for his research project HyPerGreen. In the group of Prof. Antonio Abate, HZB, Musiienko will explore and improve lead-free perovskite solar cells with the goal to increase their efficiency to more than 20 %.
