Anion-Vacancy Defect Passivation for Efficient Antimony Selenosulfide Solar Cells via Magnesium Chloride Post-growth Activation.

The quasi-1D antimony selenosulfide (Sb(S,Se)) light-harvesting material has attracted tremendous attention for photovoltaic applications because of its superior materials and optoelectronic properties. However, one of the critical obstacles faced by Sb(S,Se) solar cells is the presence of many defects in absorbers, especially those deep-level anion-vacancy defects which are prone to serving as recombination centers. In this work, an effective defect engineering strategy via magnesium chloride (MgCl) postgrowth activation is explored for high performance antimony selenosulfide solar cells.

Exploration and breakthrough in the mode of intervertebral disc cell death may lead to significant advances in treatments for intervertebral disc degeneration.

Low back pain caused by intervertebral disc degeneration (IDD) has emerged as a significant global public health concern, with far-reaching consequences for patients' quality of life and healthcare systems. Although previous research have revealed that the mechanisms of intervertebral disc cell apoptosis, pyroptosis and necroptosis can aggravate IDD damage by mediating inflammation and promoting extracellular matrix degradation, but they cannot explain the connection between different cell death mechanisms and ion metabolism disorders. The latest study shows that cell death mechanisms such as cellular senescence, ferroptosis, and cuproptosis, and PANopotosis have similar roles in the progression of intervertebral disc degeneration, but not exactly the same damage mechanism.
