Pigment stabil und katalytisch aktiv

Coating of Single Atomic Layers for Zinc Sulfide

Stable and Catalytically Active Pigment


It is one of the softest white pigments used by the industry. However, zinc sulfide turns gray over time if it is not appropriately pretreated. Chemists under the leadership of the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) discovered a way to retain its brilliant color and also enable its use as a catalyst; for example, to convert sunlight into usable energy. The scientific journal "Advanced Functional Materials" covers the topic in its latest issue.

Award for Electrochemist

Predicting the Performance of Catalysts


Green electricity should be available as soon as possible, at best from all power outlets: electrochemical processes are the basis for a sustainable energy, but they need new, high-performance catalyst materials. Theoretical calculations help to avoid dead ends and to focus on the most promising candidates. A chemist from the CRC 247 has decisively improved this performance prediction and has now received an award for his achievements. He published his work in the trade journal Electrochimica Acta.

Success of Interdisciplinary Collaboration

Switching Off the "Survival Protein" for Cancer Cells


It is called the "survival protein" because it plays a central role in the growth of cancer cells: survivin influences two important processes in the body's cells at the same time – cell death and cell division. Chemists and biologists from the CRC 1093 and CENIDE have now succeeded in developing a precise molecule that can bind the protein’s surface at a defined site and switch it off. "Nature Communications" covers the topic.


Neue Spule ist Allround-Talent

Breakthrough for Magnetic Resonance Imaging

New Antenna is an All-round Talent


Anyone needing a tomography gets the clearest possible images of an organ or other body structure slice by slice. But the further inside the potential problem lies, the more difficult it is to obtain high-resolution images in magnetic resonance imaging. An international team of scientists led by the University of Duisburg-Essen (UDE) has developed a high-frequency coil that allows for much better range inside the body – among other advantages. The scientific journal "Nature Communications" covers the topic.


Synthese anorganischer Heteroalkene

Future options for storing CO2

Synthesis of Inorganic Heteroalkenes


Group 13/15 heteroalkenes RMER' with M-E double bonds (M = B-Tl; E = N-Bi) offer promising potential for bond activation reactions, but they are difficult to prepare. A team led by CENIDE professor Stephan Schulz now describes new synthetic methods for group 13 metallapnictenes in no less than three articles in the journal "Angewandte Chemie". They allow for the preparation of preparative amounts as a basis for systematic reactivity studies.


Frohe Festtage!

Robotic Arm Helps with Analysis

Catalytic Activity of Individual Particles


Analyzing tiny nanoparticles separately is a challenge.A team from the University of Duisburg-Essen (UDE) and Ruhr-Universität Bochum has developed a new technique that could make the process much easier. The journal "Angewandte Chemie" covers the method in its latest issue.


Licht schwächt magische Nanoteilchen
F. Muckel et. al., Nat Commun 11, 4127 (2020), CC 4.0

Research on Semiconductors

Light Weakens Magic Nano Clusters


They are known as "magic sized nano clusters" because they have special properties: The particles consist of only a few atoms, but since they are arranged in a special crystal structure, they are extremely stable. Unless you expose them to light. Scientists from the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) have discovered that such materials undergo fundamental changes as soon as they are merely analysed using optical methods. "Nature Communications" reports on the issue.

2.3 Million € for Battery Project by UDE and Evonik

Better Anode Material for Lithium Ion Batteries


It is expected to be market-ready by 2023: Anode material for lithium ion batteries, leading to more powerful energy storage systems. The material has already been tested in the laboratories of the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE). Since September 1, the German Federal Ministry of Economics is funding UDE with almost 1.7 million Euro to further develop the synthesis process in a joint project with Evonik and transfer it to industrial scale.


Flexible Leuchtelemente in 2D

Scalable growth process

Flexible light emitting elements in 2D


If 80,000 of them were piled on top of each other, the stack would only be as high as a flat sheet of paper. Scientists from the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) and cooperation partners have developed a layer of tungsten disulfide that is just as thin as three atomic layers – and it is luminous, flexible and also withstands external influences. Several square centimeters of this layer have already been embedded in structural components, but the manufacturing process is scalable beyond that, the trade journal Advanced Optical Materials reports.


Erste fachübergreifende Tagung

Jointly Promoting Catalysis Research

First Interdisciplinary Conference


Catalysis initiates central processes of our entire life on earth - from enzyme catalysis in metabolic processes in all organisms to natural photosynthesis and the production of synthetics and environmentally friendly energy sources. Scientists in four Collaborative Research Centres (CRCs) of the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) are currently investigating how these fundamental and at the same time diverse processes of chemical catalysis work exactly and how their principles can be used for sustainable value creation.

High-ranking keynote speakers will present and discuss current developments. Registration deadline for the conference organized by the Center for Nanointegration Duisburg-Essen (CENIDE) is December 6.


Katalysatormaterial aus dem Laserlabor

Industrial Relevance Proven

Catalyst Material from the Laser Lab


In catalysts, more surface area usually equals more activity. And hardly anything offers more surface than structures made of nanoparticles. Scientists from the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) have shown that it makes sense in economic terms to produce catalytically highly active particles by laser. Not only are they extremely pure, but even at low temperatures they are more efficient than their conventionally produced counterparts. This has been demonstrated in tests conducted by an industrial partner.


Verflochtene Katalysatoren

Interlocked Molecules Provide High Product Selectivity

Entangled Catalysts


They are inseparable, but not rigidly connected: Mechanically interlocked molecular architectures have only recently been discovered. They can look like two connected chain links or a ring on an axis closed on both sides, for example. Chemists from the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) have now successfully tested them as cooperative catalysts for the first time. Two renowned trade journals have reported on this.


Eine Prise Nanosilber

3D Laser Printing in Color

Seasoning with Nanosilver


Ventilation grilles in aircraft cabins, serial components in cars and lately even mascara brushes: The industry has been using laser-based 3D printers for several years now when precision and good mechanical properties are required. However, these printers are expensive, large and print only in white. For home use, desktop devices are becoming available, but they can only print in black – until now. A team from the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) has now brought color into play.

Energy conversion

Challenges in the development of electrocatalysts


Efficient catalysts are crucial for energy conversion. However, findings from basic research rarely make it into practice at present. What would have to change to develop efficient, stable and selective catalysts for industrial application is described by Prof. Dr. Corina Andronescu from the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) and partners from the Max Planck Institute for Chemical Energy Conversion and Ruhr-Universität Bochum in a review article. It was published online in the journal “Angewandte Chemie” on 30 June 2020.

Humboldt Fellow at NETZ

Nanocatalysts Made of Metallic Glass


They combine the properties of metal and glass and thus reveal new possibilities: Among other features, metallic glasses have extraordinary catalytic properties. Dr. Shunxing Liang intends to exploit this for water splitting, i.e. the production of hydrogen as an energy carrier. To this end, he wants to generate nanoparticles of this promising material by pulse laser ablation in liquids. The 29-year-old is a Humboldt Fellow at the NanoEnergieTechnik-Zentrum (NETZ) at the University of Duisburg-Essen (UDE) for one year.


Kuprat-ähnliches Verhalten in einem Nickeloxid-Film

Superconducting nickelates

Cuprate-like behavior in a nickel-oxide film


Superconductors transmit electric current without loss at any distance and play an important role in quantum computers and medical imaging. Unfortunately, the stars among the electrical conductors work exclusively at extremely low temperatures. Since the discovery of high-temperature superconducting cuprates with their characteristic copper-oxygen plaquettes in 1986, scientists have been searching for similar behavior in other materials classes. It was not until 2019 that superconductivity was reported in a nickel oxide, but the underlying mechanism is still unclear. Theoretical physicists from the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) have therefore studied the electronic properties of the material and found a possible explanation.

Potential Beginning of Life Simulated in Lab

Evolution Underground


Did life originate not on the ground but underground? Scientists at the University of Duisburg-Essen (UDE) have substantiated their theory that first life could have begun deep in the earth's crust. In their experiments at the Center for Nanointegration (CENIDE), inanimate structures developed survival strategies within a short time. The scientists’ book on the topic will be published in July.

Publication in Science on Nanooptics

New Form of Microscopy Developed


The duration of their snapshot relates to one second as one second relates to the age of the universe: In a joint collaboration with Australian Scientist Tim Davis and the Group around Harald Gießen (University of Stuttgart), Physicists from CENIDE have developed ultrafast vector microscopy as a way of determining electric fields on surfaces with high temporal and spatial resolution. The new method was used to measure the dynamics of optical skyrmions in the time domain for the first time. The renowned journal "Science" publishes this breakthrough in nanooptics in its current issue.


Materialeigenschaften durch Dehnen verändern

Science Publication on New Technology

Changing Material Properties by Stretching


Unlike ductile metals, oxides are ceramics, known to be brittle and unable to sustain large strains. An international team of scientists, including theoretical physicists from the UDE, were successful in achieving extreme strains of up to 8 percent in oxide membranes.
