A Longer Life for Organic Solar Cells
By Philipp Jarke Photovoltaic cells made of organic materials are light and flexible, which is why they are considered very promising. An international research network led by TU Graz is now aiming to increase the stability of the materials. Solar cells made of silicon have been around for 70 years. Organic solar cells, on the other hand, are quite new, but open up new possibilities for emission-free electricity production.

How organic solar cells could become significantly more efficient
Organic dyes accelerate transport of buffered solar energy The sun sends enormous amounts of energy to the earth. Nevertheless, some of it is lost in solar cells. This is an obstacle in the use of organic solar cells, especially for those viable in innovative applications. A key factor in increasing their performance: Improved transport of the solar energy stored within the material.

Crystallization as the Driving Force
Scientists from the Friedrich Schiller University of Jena and the Friedrich Alexander University of Erlangen-Nuremberg have successfully developed nanomaterials using a so-called bottom-up approach. As reported in the scientific journal ACS Nano, they exploit the fact that crystals often grow in a specific direction during crystallisation.

Scientists make methanol at room temperature
A more sustainable method of creating methanol - a key component of fuels, plastics, and medicines - has been developed by Cardiff scientists and an international team of collaborators. The process, which uses a highly active catalyst, converts oxygen and the natural gas methane into methanol at room temperature without the need for external energy sources such as light or electricity.

Wastewater treatment plants as drivers for the energy transition
By implementing an innovative technology, any wastewater treatment plant would be able to produce methane from carbon dioxide in an environmentally friendly way. If some microorganisms present in wastewater treatment plants are additionally supplied with hydrogen and carbon dioxide, they produce pure methane.

Technique for 3-D Printing Metals at the Nanoscale Reveals Surprise Benefit
Late last year, Caltech researchers revealed that they had developed a new fabrication technique for printing microsized metal parts containing features about as thick as three or four sheets of paper. Now, the team has reinvented the technique to allow for printing objects a thousand times smaller: 150 nanometers, which is comparable to the size of a flu virus.

Cheap and efficient catalyst could boost renewable energy storage
Storing renewable energy as hydrogen could soon become much easier thanks to a new catalyst based on single atoms of platinum. The new catalyst, designed by researchers at City University Hong Kong (CityU) and tested by colleagues at Imperial College London, could be cheaply scaled up for mass use. The new electrocatalyst could be a major contributor to ultimately helping the UK meet its net-zero goals by 2050.

One-atom-thick ribbons could improve batteries, solar cells and sensors
Researchers at UCL have created one-atom-thick ribbons made of phosphorus alloyed with arsenic that could dramatically improve the efficiency of devices such as batteries, supercapacitors and solar cells. The research team discovered phosphorus nanoribbons in 2019. The "wonder material", predicted to revolutionise devices ranging from batteries to biomedical sensors, has since been used to increase lithium-ion battery lifetimes and solar cell efficiencies.

New recipes for origin of life may point way to distant, inhabited planets
Life on a faraway planet - if it's out there - might not look anything like life on Earth. But there are only so many chemical ingredients in the universe's pantry, and only so many ways to mix them. A team led by scientists at the University of Wisconsin-Madison has exploited those limitations to write a cookbook of hundreds of chemical recipes with the potential to give rise to life.

A human model for autism
The CRISPR-Cas gene scissors enable researchers to study the genetic and cellular causes of autism in the lab - directly on human tissue. How does autism develop? Which genes and cells in the human brain contribute to it? A new brain organoid model allows researchers from the Department of Biosystems at ETH Zurich in Basel and colleagues from Vienna to investigate these questions in human cells.

Individual neurons mix multiple RNA edits of key synapse protein
Neurons stochastically generated up to eight different versions of a protein-regulating neurotransmitter release, which could vary how they communicate with other cells. Neurons are talkers. They each communicate with fellow neurons, muscles, or other cells by releasing neurotransmitter chemicals at "synapse" junctions, ultimately producing functions ranging from emotions to motions.

New model to help valorize lignin for bio-based applications
Woody biomass and wheat straw are all sources of the natural polymer lignin with more than 50 megatons of lignin produced annually at commercial scale. However, most is burned to produce energy, which alternatively could be used to make useful chemicals. A major issue with producing chemicals from lignin though is that the properties of lignin vary from source to source and from season to season.

Liverpool chemists solve long-standing polymer science puzzle
New research by the University of Liverpool's Chemistry Department represents an important breakthrough in the field of polymer science. In a paper published in the journal Nature Chemistry, and featuring on the front cover, Liverpool researchers use mechanochemistry to characterise how a polymer chain in solution responds to a sudden acceleration of the solvent flow around it.

Precisely arranging nanoparticles
Research team at Göttingen University develops plasmonic molecules from nanoparticles In the incredibly small world of molecules, the elementary building blocks - the atoms - join together in a very regular pattern. In contrast, in the macroscopic world with its larger particles, there is much greater disorder when particles connect.
