In a new breakthrough that could revolutionise medical and material engineering, scientists have developed a first-of-its-kind molecular device that controls the release of multiple small molecules using force. The researchers from The University of Manchester describe a force-controlled release system that harnesses natural forces to trigger targeted release of molecules, which could significantly advance medical treatment and smart materials.

Team from the University of Münster presents computer-aided method / Counteracting subjective bias in studies on the production of new chemical compounds Chemists often develop and optimise new chemical reactions using so-called model systems, i.e. simple, easily accessible substrates.

Scientists found for the first time a natural protein that follows a mathematical pattern of self-similarity An international team of researchers led by groups from the Max Planck Institute in Marburg and the Philipps University in Marburg has stumbled upon the first regular molecular fractal in nature.

Mixing unconventional ingredients in just the right order can make complex materials with fewer impurities. The robotic lab that tested the idea could be widely adopted. Study: Navigating phase diagram complexity to guide robotic inorganic materials synthesis (DOI: 10.1038/s44160'024 -00502-y) New chemistries for batteries, semiconductors and more could be easier to manufacture, thanks to a new approach to making chemically complex materials that researchers at the University of Michigan and Samsung's Advanced Materials Lab have demonstrated.

Researchers at The University of Manchester have achieved a groundbreaking advancement in catalyst technology. They have developed a new catalyst which has been shown to have a wide variety of uses and the potential to streamline optimisation processes in industry and support new scientific discoveries.

A new molecular test method helps to prove the authenticity of works of art. The new method could also help to make passwords secure against quantum computers. Security experts fear Q-Day, the day when quantum computers become so powerful that they can crack today's passwords. Some experts estimate that this day will come within the next ten years.

Key Takeaways New automated workflow could enable real-time reaction analysis from a desktop computer instead of in a lab. Unlike conventional benchtop methods, the automated workflow could identify new chemical reaction products within a few hours instead of days. Could accelerate pharmaceutical drug discovery and development of new chemical reactions.

Study: C. elegans chromosome end protection proteins TEBP-1 and TEBP-2 adapt the Myb module to dimerize and bind telomeric DNA (DOI: 10.1073/pnas. University of Michigan researchers have discovered that a worm commonly used in the study of biology uses a set of proteins unlike those seen in other studied organisms to protect the ends of its DNA.

Progress in biomedical imaging with PyrAt compounds Fluorescent molecules enable the visualization of tissue and cells and are therefore indispensable in medicine and pharmacy. A team led by Nuno Maulide and Leticia González from the Faculty of Chemistry at the University of Vienna and Harald Sitte from MedUni Vienna has developed a series of novel fluorescent molecules.

April 5, 2024 New research shows: key molecules within nerve cells persist throughout life Most human nerve cells last a lifetime without renewal. A trait echoed within the cells' components, some enduring as long as the organism itself. New research by Martin Hetzer, molecular biologist and president of the Institute of Science and Technology Austria (ISTA), and colleagues discovered RNA, a typical transient molecule, in the nerve cells of mice that remain stable for their entire lives.

The low-cost hardware outperforms state-of-the-art versions and could someday enable an affordable, in-home device for health monitoring. Mass spectrometry, a technique that can precisely identify the chemical components of a sample, could be used to monitor the health of people who suffer from chronic illnesses.

Hydrogen chloride can now be stored, processed, and electrolyzed safely thanks to breakthrough by research team at Freie Universität Berlin A research team at Freie Universität Berlin led by Professor Sebastian Hasenstab-Riedel has successfully developed a method for storing and electrolyzing gaseous hydrogen chloride in the form of an ionic liquid.

Study shows neutrons can bind to nanoscale atomic clusters known as quantum dots. The finding may provide insights into material properties and quantum effects. Neutrons are subatomic particles that have no electric charge, unlike protons and electrons. That means that while the electromagnetic force is responsible for most of the interactions between radiation and materials, neutrons are essentially immune to that force.

An international research team is attracting the attention of experts in the field with computational results on the behavior of ring polymers under shear forces: Reyhaneh Farimani, University of Vienna, and her colleagues showed that for the simplest case of connected ring pairs, the type of linkage - chemically bonded vs.

Analysing the diversity of organic compounds dissolved in freshwater provides a reliable measure of ecosystem health, say scientists. Our technique is a very simple way to get a comprehensive overview of what's going on in a particular river or lake. Jérémy Fonvielle The source of pollutants in rivers and freshwater lakes can now be identified using a comprehensive new water quality analysis, according to scientists at the University of Cambridge and Trent University, Canada.

UdeM doctoral candidate in physics Emmanuel Bourret leads an international research group that has discovered C130, a rare carbon molecular structure. For years, C 130 fullertubes-molecules made up of 130 carbon atoms-have existed only in theory. Now, leading an international team of scientists, an UdeM doctoral candidate in physics has successfully shown them in real life - and even managed to capture some in a photograph.

A research project at EPFL succeeded in decoding the complex dance of electrons in water, a major step in understanding a critical process of many chemical phenomena, and that might be the first step to improving energy conversion technologies. Water, the cradle of life on Earth, is not just a passive backdrop but actively participates in the chemical ballet of life.

A catalyst tethered by DNA boosts the efficiency of the electrochemical conversion of CO2 to CO, a building block for many chemical compounds. MIT chemical engineers have devised an efficient way to convert carbon dioxide to carbon monoxide, a chemical precursor that can be used to generate useful compounds such as ethanol and other fuels.

A University of Queensland-led study has shed light on how some lizards have evolved to resist deadly neurotoxins from Australia's most venomous snakes. The research, led by UQ's Professor Bryan Fry , focused on the interactions between venomous Australian snakes such as death adders, and the varanid lizard species which includes Komodo dragons and goannas.

A breakthrough in catalysis research leads to a new wall paint that cleans itself when exposed to sunlight and chemically breaks down air pollutants. Typically, beautiful white wall paint does not stay beautiful and white forever. Often, various substances from the air accumulate on its surface. This can be a desired effect because it makes the air cleaner for a while - but over time, the colour changes and needs to be renewed.
