| Where does gold come from? New insights into element synthesis in the universe Posted: 15 Nov 2021 09:34 AM PST How are chemical elements produced in our Universe? Where do heavy elements like gold and uranium come from? Using computer simulations, a research team shows that the synthesis of heavy elements is typical for certain black holes with orbiting matter accumulations, so-called accretion disks. The predicted abundance of the formed elements provides insight into which heavy elements need to be studied in future laboratories to unravel the origin of heavy elements. |
| Bulletproof fingerprint technology takes images in the round Posted: 15 Nov 2021 09:34 AM PST Experts have developed a unique method for retrieving high resolution images of fingermarks from curved objects like bullet casings that offers greater detail and accuracy than traditional forensic methods. |
| Posted: 15 Nov 2021 09:34 AM PST More than 70% of microplastics found in samples from oceans and rivers could come from the scientists collecting them. A new article investigates procedural contamination when sampling for microparticles in aquatic environments. The study shows that a significant amount of microplastics and microfibres from scientists' clothing and gear mixes with environmental pollution in the water samples. |
| Liquid fuels from carbon dioxide Posted: 15 Nov 2021 09:34 AM PST A new electrocatalyst called a-CuTi@Cu converts carbon dioxide (CO2) into liquid fuels. Active copper centered on an amorphous copper/titanium alloy produces ethanol, acetone, and n-butanol with high efficiency. |
| New polymer detection method to turn the (pep)tide in the fight against water pollution Posted: 11 Nov 2021 10:02 AM PST A peptide sensor to detect water-soluble polymers in wastewater, a major contributor to pollution on par with microplastics, has been developed. The new technique takes advantage of the bonding that occurs between peptides and different polymers to train a machine learning algorithm that can both identify and quantify a large number of pollutants in a single solution. |
