UrduIf you plan on getting a tattoo, consider this: A new study from Binghamton University, State University of New York looking at green and blue tattoo inks from Europe found that most contained ingredients that are not listed on the label – and some contained ingredients that are outright banned.

High-Speed Camera for Molecules: Entangled Photons Enabled Raman Spectroscopy
This scheme significantly improves the frequency-time resolution of spectra, yielding elaborate HOM interference which enables the selective access of stimulated Raman scattering. In addition, no grating is required for detection, simplifying the experimental setup.
Some landfill ‘burps’ contain airborne PFAS, study finds
Many municipal landfills “burp” gas from decomposing organic matter rather than letting it build up. And burps from buried waste containing per- and polyfluoroalkyl substances (PFAS) can release these “forever chemicals” into the air, say researchers in ACS’ Environmental Science & Technology Letters.
Cost-effective, high-capacity, and cyclable lithium-ion battery cathodes
Charge-recharge cycling of lithium-superrich iron oxide, a cost-effective and high-capacity cathode for new-generation lithium-ion batteries, can be greatly improved by doping with readily available mineral elements.
How Scientists Are Accelerating Chemistry Discoveries With Automation
Researchers have developed an automated workflow that could accelerate the discovery of new pharmaceutical drugs and other useful products. The new approach could enable real-time reaction analysis and identify new chemical-reaction products much faster than current laboratory methods.
Water-based paints: Less stinky, but some still contain potentially hazardous chemicals
Choosing paint for your home brings a lot of options: What kind of paint, what type of finish and what color? Water-based paints have emerged as “greener” and less smelly than solvent-based options. And they are often advertised as containing little-to-no volatile organic compounds (VOCs).
Toxic metal particles can be present in cannabis vapes even before the first use
Vapes are thought to be a “safer” way to consume cannabis, but they present their own risks. Researchers have discovered toxic metal particles in vaping liquids even before first use of the device, and this toxicity was worse in illicit products. They will present their results at ACS Spring 2024.
A FORCE to be reckoned with: Computer modeling for optimal energy partnerships
Integrating nuclear power into broader energy systems, including renewable energy sources and heat-intensive industries, could improve flexibility and unlock revenue streams for nuclear power producers.
What makes those pandemic-era sourdoughs so deliciously, uniquely, sour?
Sourdough bread-making took over amid lockdown boredom. Today, scientists report the 21 key chemical compounds responsible for its one-of-a-kind taste and smell. They will present their results at ACS Fall 2023.
Unlocking early Earth chemistry: Salt-induced changes in polyester microdroplet structure
A team of researchers have recently come up with a new strategy for investigating the effect of salt uptake on polyester microdroplets.
Influenza or a cold? A new technology can help you
Some people do such smart and difficult things that it’s hard to see what in the world they might have to do with you and me, so we just shrug them off. But that’s often the wrong response.
Exposing what’s in tattoo ink
Tattoo inks are unregulated in the U.S. A team has analyzed what is in some inks, and it doesn’t always match what’s on ingredient labels. Once the study is complete, they will publish their results on a website for consumers and tattoo artists. They will present their results at ACS Fall 2022.
