Photocatalytic process enables water to be activated Hydrogen is seen as an energy source of the future - at least, when it is produced in a climate-friendly way. Hydrogen can also be important for the production of active ingredients and other important substances. To produce hydrogen, water (H2O) can be converted into hydrogen gas (H2) by means of a series of chemical processes.

Shape-shifting cells at the flick of a switch
Research team with Göttingen University uses light to reversibly change the shape of red blood cells Membranes are crucial to the functioning of living cells: they separate the cells from the environment and protect them; they transport nutrients into the middle of the cell; and they are vital when cells grow together to form tissues, reproduce by division or move around.

Light-switchable molecules in membranes enable different forms of living cells to be studied Membranes fulfil a variety of tasks in living cells: for example, they separate the cells from their surroundings and thus protect them. Also, by means of transport proteins they convey the necessary nutrients to the interior.

News from Living organisms use powerful physical principles to control interactions at their surfaces. Researchers at the Leibniz Institute of Polymer Research Dresden, Leipzig University and TU Dresden have now discovered why cholesterol-containing surfaces can exhibit greatly reduced attachment of proteins and bacteria.

Research team develops organic redox polymer as positive electrode material for aluminium-ion batteries Aluminium-ion batteries are seen as a promising alternative to conventional batteries that use scarce and difficult-to-recycle raw materials such as lithium. This is because aluminium is one of the most common elements in the Earth's crust, is easier to recycle, and is also safer and less expensive than lithium.

Emergence of solvated dielectrons observed for the first time
Team in conjunction with the University of Freiburg generates low-energy electrons using ultraviolet light Solvated dielectrons are the subject of many hypotheses among scientists, but have never been directly observed. They are described as a pair of electrons that is dissolved in liquids such as water or liquid ammonia.

Cis-tetrahydrocannabinoids can now be produced synthetically, enabling pharmaceutical applications A group of researchers at Leipzig University has developed a new method for synthesising cis-tetrahydrocannabinol (THC) - a natural substance found in the cannabis plant that produces the characteristic psychoactive effect and has many potential applications, including in the pharmaceutical industry.

At certain times in the year, more soot particles reach the Amazon rainforest from bush fires in Africa than from regional fires. Up to two-thirds of the soot above the central Amazon rainforest originates in Africa. These are the results of a study that has now been published in Nature Communications Earth and Environment.

Glass is a very special material: it can be produced in almost unlimited variety from compounds of almost all'elements of the periodic table. The only prerequisite is that the components can be melted together and that the melt is then cooled quickly enough. In the process, the liquid mixture solidifies and forms a glass.

New synthetic metabolic pathways for fixation of carbon dioxide could not only help to reduce the carbon dioxide content of the atmosphere, but also replace conventional chemical manufacturing processes for pharmaceuticals and active ingredients with carbon-neutral, biological processes. A new study demonstrates a process that can turn carbon dioxide into a valuable material for the biochemical industry via formic acid.

More soot particles reach the central Amazon rainforest from brush fires in Africa than from regional fires at some times. Up to two-thirds of the soot over the central Amazon rainforest originates in Africa. This is the result of a study now published in Nature Communications Earth and Environment.

Chemistry and physics, traditionally separate disciplines, are intermeshed in nano-technology The area where physics and chemistry meet lies somewhere in the realm of the minute - in the nano range: where molecules react with one another and the laws of quantum mechanics hold sway. This is the area which physicist Dr. Harry Mönig visualises at the Center for Nanotechnology (CeNTech) - with an atomic force microscope and a dedicated technology perfected by himself and a Münster team.

Breakthroughs in ancient genome reconstruction and biotechnology are now revealing the rich molecular secrets of Paleolithic microorganisms. In a new study published in "Science", a transdisciplinary team of researchers led by the Leibniz Institute for Natural Product Research and Infection Biology, the Max Planck Institute for Evolutionary Anthropology, Friedrich Schiller University Jena and Harvard University reconstructed bacterial genomes of previously unknown bacteria dating to the Pleistocene.

A previously unknown form of hydrogel formation has been elucidated: chemists found unusual interactions between polymers. Hydrogels? Many people use these substances without knowing it. As superabsorbents in nappies, for example, hydrogels absorb a lot of liquid. In the process, the initially dry material becomes Jelly-like, but it does not wet.

Ammonia synthesized in sun-rich countries could facilitate sustainable ironand steelmaking When it comes to sustainability and green steel, everybody talks about hydrogen. But current means of storing and transporting hydrogen request high pressures and low temperatures, which are both energetically and economically costly.

Some materials convert photons into more free charges than would be expected. Using an ultrafast film, researchers have now been able to get a picture of this process. Physicists from the University of Würzburg were also involved. Photovoltaics, the conversion of light to electricity, is a key technology for sustainable energy.

Quantum effects demonstrated in the collision of hydrogen molecules with noble gas atoms
A research team of Freie Universität Berlin has shown how hydrogen molecules behave quantum mechanically when they collide with noble gas atoms such as helium or neon. In the study published in the journal "Science," the scientists used simulations to establish a direct link between measurements of atoms and molecules taken in experiments and theoretical models; the study includes both theoretical calculations and data from experiments conducted at the Technical University of Dortmund and the Weizmann Institute of Science (Israel).

Quantum Effects Detected in Hydrogen and Noble Gas Collisions
Study by Freie Universität quantum physicist Professor Christiane Koch published in "Science" A Freie Universität Berlin research team headed by quantum physicist Professor Christiane Koch has demonstrated how hydrogen molecules behave when they collide with noble gas atoms such as helium or neon. In an article published in the journal Science , the researchers describe how they used simulations to draw connections between data from experiments and theoretical models of quantum physics ( www.science.org/doi/abs/10.1126/science.adf9888 ).

Reading time 4 min. Progress with organoids A team at the Technical University of Munich (TUM) has induced stem cells to emulate the development of the human heart. The result is a sort of "mini-heart" known as an organoid. It will permit the study of the earliest development phase of our heart and facilitate research on diseases.
