Size dependent change of mean square displacement in gold nanocrystals: A molecular dynamics simulation
(Wiley, 2023-11-01)Thermally activated atomic vibrations significantly decrease the x-ray diffraction intensities of nanocrystalline powders. Hence their quantification is critical for accurate structural characterization of small nanocrystals ... -
Moving from symptom management to upstream plastics prevention: The fallacy of plastic cleanup technology
(Elsevier, 2023-11-17)Plastic removal technologies can temporarily mitigate plastic accumulation at local scales, but evidence-based criteria are needed in policies to ensure that they are feasible and that ecological benefits outweigh the ... -
