The stability results are among the most notable numbers in the report. After five consecutive reaction cycles, the average copper particle size increased only slightly, from 69.8 nm to 72.3 nm. The authors attribute this robustness to the interfacial interactions that hold the copper particles in place across successive batches.…
Are you sure you want to import this news into ? Secondary serotonin aptamer (green) binds to the target-bound primary serotonin aptamer (pink). 2026 EPFL CHEMINA CC BY SA EPFL scientists have reimagined how aptamers – short DNA strands used in molecular sensors – detect their targets. Their versatile sensing…
Repetitive DNA, defined as sequence motifs that recur throughout the genome, comprises about 54% of the human genome. Large amounts of repetitive DNA were long labeled “junk” or “selfish” DNA, yet growing evidence shows that…
A battery material can look perfect in the lab and still fail in a real battery. That is the puzzle facing researchers working on solid electrolytes, the materials seen as key to safer, longer-lasting batteries. For years, the race has focused on one number: how quickly ions move through the…
Ammonia is essential for global agriculture, but its production via the Haber-Bosch process is energy-intensive and emits vast amounts of CO₂. Electrocatalytic nitrogen reduction offers a greener alternative, yet breaking nitrogen’s stubborn triple bond under mild conditions has remained a major hurdle. Now, researchers have introduced a conceptually novel mechanism—hydroxide-activated…
New antiperovskite-supported cobalt catalyst can produce ammonia from nitrogen and hydrogen under mild conditions without precious metals, as reported by researchers from Science Tokyo. This self-organizing nanostructured…
Hydrogen could help industries reduce their dependence on fossil fuels, but its environmental benefits depend largely on how it is produced. Conventional hydrogen production can release substantial amounts of greenhouse gases…
