New material for efficient separation of Deuterium at elevated Temperatures

21-Mar-2025 - A novel porous material capable of separating deuterium (D2) from hydrogen (H2) at a temperature of 120 K has been introduced. Notably, this temperature exceeds the liquefaction point of natural gas, thus facilitating large-scale industrial applications. This advancement presents an attractive ...

New procedure for better thermoplastics

New insights thanks to nano imaging and spectroscopy at the IRIS beamline of BESSY II

06-Nov-2024 - Bio-based thermoplastics are produced from renewable organic materials and can be recycled after use. Their resilience can be improved by blending bio-based thermoplastics with other thermoplastics. However, the interface between the materials in these blends sometimes requires enhancement to ...

From waste to value: The right electrolytes can enhance glycerol oxidation

"Our research could help to convert biomass by-products into valuable chemicals more efficiently"

03-Jul-2024 - When biomass is converted into biodiesel, huge amounts of glycerol are produced as a by-product. So far, however, this by-product has been little utilised, even though it could be processed into more valuable chemicals through oxidation in photoelectrochemical reactors. The reason for this: low ...

Green hydrogen: Co-production of valuable chemicals boosts profitability

Co-production concept is very flexible; different products can be produced in the same plant depending on demand

10-Oct-2023 - It is clear that it works: There are already approaches today to use solar energy for the electrolysis of water and to produce hydrogen. Unfortunately, this "green" hydrogen has so far been more expensive than "gray" hydrogen from natural gas. But the production of green hydrogen with sunlight ...

HZB and University of Jena found Helmholtz Institute for Polymers in Energy Applications

Developing internationally competitive energy materials

22-Jun-2023 - Friedrich Schiller University Jena and the Helmholtz-Zentrum Berlin (Helmholtz Centre for Materials and Energy, HZB) are jointly founding the "Helmholtz Institute for Polymers in Energy Applications" (HIPOLE) on 1 July 2023. The aim of HIPOLE is to develop sustainable polymer materials for energy ...

New insights into switchable MOF structures

03-Jun-2021 - Metal-organic framework compounds (MOFs) are widely used in gas storage, material separation, sensor technology or catalysis. A team led by Prof. Dr. Stefan Kaskel, TU Dresden, has now investigated a special class of these MOFs at the MX beamlines of BESSY II. These are "switchable" MOFs that can ...

"Molecular scissors" for plastic waste

15-Apr-2019 - A research team from the University of Greifswald and Helmholtz-Zentrum-Berlin (HZB) has solved the molecular structure of the important enzyme MHETase at BESSY II. MHETase was discovered in bacteria and together with a second enzyme - PETase - is able to break down the widely used plastic PET ...

Molecules that self-assemble into monolayers for efficient perovskite solar cells

28-Nov-2018 - A team at the HZB has discovered a new method for producing efficient contact layers in perovskite solar cells. It is based on molecules that organise themselves into a monolayer. In recent years, solar cells based on metal halide perovskites have achieved an exceptional increase in efficiency. ...

Measuring chemistry: local fingerprint of hydrogen bonding captured in experiments

21-Mar-2016 - A team from Helmholtz-Zentrum Berlin has been able for the first time to measure how new bonds influence molecules: they have reconstructed the “energy landscape” of acetone molecules using measurement data from the Swiss Light Source (SLS) of the Paul Scherrer Institut, and thereby empirically ...

Current loss tracked down by magnetic fingerprint

HZB researchers solve the case of lost current in organic solar cells

28-Oct-2010 - Scientists have been working on organic solar cells for about a decade. Their manufacture is environmentally friendly and they can be applied to all kinds of materials, such as plastic film, for instance. The trouble is, they only yield a fifth of the electrical energy that silicon solar cells ...
