Through reactions of laser-ablated uranium atoms with methylene halides CH2XY (XY = F2, FCl, and Cl2), a series of new actinide methylidene molecules CH2═UF2, CH2═UFCl, and CH2═UCl2 are formed as the ...

Past studies of the various separable carbonaceous fractions have been unable to account for all of C in primitive chondrites. In particular, up to 20-50% of the C is lost during acid leaching of bulk ...

We test the relationship between canopy photosynthesis and reflected near-infrared radiation from vegetation across a range of functional (photosynthetic pathway and capacity) and structural ...

SUMMARY: The Environmental Protection Agency (EPA or Agency) is proposing to extend the compliance date applicable to certain entities subject to the regulation of methylene chloride recently ...

In this study, the potential of rice husk ash (RHA) to act as an adsorbent for treating dye-containing wastewater was demonstrated. The RHA used in this study contained 91.7% silica, which was ...

The US Environmental Protection Agency (EPA) on May 20 proposed to extend the deadline for laboratories to comply with its methylene chloride rule by 18 months. The rule, finalized in May 2024 ...

On May 20, 2025, the U.S. Environmental Protection Agency (EPA) released a proposed rule that would extend certain compliance dates in the final risk management rule for methylene chloride under ...

An additional tweak to the contact lenses allows users to differentiate between different spectra of infrared light by engineering the nanoparticles to color-code different infrared wavelengths ...
