Flocculation and sedimentation characteristic of coal slurry in coal preparation plant

IOP Conference Series: Earth and Environmental Science, 2019
Abstract Flocculation sedimentation test was carried out on the coal slurry of the selected coal preparation plant. A mathematical correlation model of initial settling velocity, upper clarification turbidity and sediment volume with various influencing factors was established.

Zinc Exposure Causes Disulfidptosis to Induce Miscarriage by Up‐Regulating GATA1/METTL1/SLC7A11 Axis

Advanced Science, EarlyView.
Zn exposure up‐regulates GATA1, promoting GATA1‐mediated METTL1 and SLC7A11 transcription. It also enhances METTL1‐mediated m7G modification on SLC7A11 mRNA, increasing SLC7A11 mRNA stability. Ultimately, Zn exposure up‐regulates SLC7A11 at both transcriptional and post‐transcriptional levels, causing disulfidptosis. Knockdown of murine Slc7a11, Gata1,

Improved Systemic Immunochemotherapy Employing an Oxaliplatin‐TLR7/8 Agonist Prodrug Strategy

Advanced Science, EarlyView.
A platinum(IV) prodrug is developed to systemically deliver the TLR7/8 agonist gardiquimod. Tumor‐targeting is mediated by an albumin‐binding maleimide, which limits premature complex activation. Ox‐Gardi‐Mal accumulates specifically in the tumor, where it activates the immune system.
