Artificial photosynthesis: Chemists develop dye stacks that mimic energy conversion in plants
What does a stack of four dyes synthesized in Würzburg look like? This represents an additional step into artificial photosynthesis as it absorbs light energy and travels quickly and efficiently into the stack. Credit: Leander Ernst / University of Wuerzburg Artificial photosynthesis allowed humans to use solar energy to combine carbon dioxide and produce hydrogen. Chemists from Würzburg and Seoul…

Using the generated AI, chemists quickly calculate the 3D genome structure.
LUSTRATION in the subsequent procedure and chromogen followed by using sequence data to create a chromatin tissue. Credit: Greg Schuette et al All cells in the body contain the same genetic sequence, but each cell expresses only the subset of those gene. These cell -specific genetic expression patterns that guarantee that brain cells are different from skin cells are partially…

Chemists discover easy way to make biodiesel from waste oil
Graphical summary. Credit: Energy and Fuels (2024). DOI: 10.1021/acs.energyfuels.4c03643 Chemists at the University of California, Santa Cruz have discovered a new way to make biodiesel from waste oil that simplifies the process and requires relatively mild heat. The discovery has the potential to make alternative fuel sources more attractive to the large industrial sector that is the backbone of the…

Chemists say it’s time to break 100-year-old rules and rewrite textbooks
Credit: Pixabay/CC0 Public Domain Chemists at UCLA have discovered a big problem with the basic rules of organic chemistry that have existed for 100 years. That’s not true at all. And they say, “It’s time to rewrite the textbooks.” Organic molecules are primarily composed of carbon and are characterized by having a specific shape and arrangement of atoms. Molecules known…

Chemists develop metal-free method to selectively convert symmetric diols into one of two enantiomers
Internal view of the photoreactor setup in operation. Credit: Science (2024). DOI: 10.1126/science.adq8029 A team of chemists at the University of Cambridge has developed a metal-free method to selectively convert symmetric diols into one of their two enantiomers. In a paper published in the journal Science, the research group exploits the ability of the chiral form of quinuclidine (quinuclidine is…

Chemists develop chiral DNA catalyst for asymmetric catalysis
Schematic diagram illustrating the development of new strategies for synthesizing diverse DNA catalysts, making DNA catalysis accessible to those without specialized skills. Credit: Journal of the American Chemical Society Chemists at the National University of Singapore (NUS) have developed a method to create a variety of chiral deoxyribonucleic acid (DNA) catalysts by fusing DNA repair and biorthogonal chemistry, providing a…

Chemists challenge traditional views on crystal growth
Graphical summary. Credit: Matter (2024). DOI: 10.1016/j.matt.2024.08.011 Remember the old high school chemistry experiment where salt crystals precipitate from a salt solution, or rock candy crystals form from sugar water? Learn about how crystals form in these solutions It turns out that your understanding of may be wrong. A new theory elucidates the crystallization process and shows that the substance…

Bioengineers and chemists design fluorescent 3D printed structures with potential medical applications
The ring-shaped “nanohoops” emit light of different colors depending on their structure. Credit: University of Oregon Researchers at the University of Oregon have mixed fluorescent ring-shaped molecules into a new 3D printing process, using the simple process of mixing eggs and flour to make pancakes. The result is complex light-emitting structures that support the development of new classes of biomedical…

“Tameable” molecules for more sustainable catalysis: Chemists synthesize surprising gallium compound
Dr. Tobias Rüffer holds a Petri dish filled with metallic gallium, which melts at about 30°C. Photo by Jakob Müller Catalysts play a key role in the manufacture of many products we encounter in our daily lives, for example in cleaning car exhaust gases or in the chemical industry producing fertilizer. Catalysts ensure that these reactions take place with low…

Chemists discover new way to organize DNA in single-celled organisms
Conventional histone proteins form nucleosomes. Credit: Nature Communications (2024). DOI: 10.1038/s41467-024-52337-y It has only recently been discovered that single-celled organisms (bacteria and archaea) also have histones – proteins that make up DNA. Now, PhD student Samuel Schwab from Leiden University has found that histones in these organisms are much more diverse than previously thought. Schwab and his colleagues describe more…
