Adsorption of Chromium (VI) with Silica Coated on Iron Sand Magnetic Material Modified with Propyldiethylenetriamine

Jurnal Teknik Kimia dan Lingkungan
Chromium metal ions with an oxidation number of six (Cr (VI)) were heavy metals that are toxic and harmful to the environment that pollute the environment from industrial waste, so efforts are needed to overcome the metal ion waste.

Molecular Palaeontology Prospects From Exceptionally Preserved Eocene Brackish‐Water Bivalve Batissa sitakaraensis (Venerida: Corbiculidae) From Hokkaido, Japan

Geological Journal, EarlyView.
This study reports the exceptional preservation of the Eocene freshwater bivalve Batissa sitakaraensis from Hokkaido, Japan. Multimodal analyses reveal that both the aragonitic shell mineralogy and the delicate organic periostracum retain their original structural and chemical characteristics after millions of years.
