Mitochondria-derived ROS activate AMP-activated protein ...

Mitochondrial reactive oxygen species (ROS) production is a tightly regulated redox signal that transmits information from the organelle to the cell. Other mitochondrial signals, such as ATP, are sensed by enzymes, including the key metabolic sensor and regulator, AMP-activated protein kinase (AMPK). AMPK responds to the cellular ATP/AMP and ATP/ADP ratios by matching mitochondrial ATP ...

Comminution

The most common grinding mills are either (a) semi-autogenous and autogenous mills; or, (b) ball mills. A semi-autogenous mill is shown in Figure 14.4. Semi-autogenous and autogenous mills have the advantage that they accept a wide range of feed sizes. Ball mills have the advantage that they deliver finely ground product to flotation.

Synthesis of Cu2ZnSnSe4 thin‐film solar cells from ...

2020-11-1 · 1 Introduction. Quaternary semiconductor Cu 2 ZnSnSe 4 (CZTSe) has drawn increased attention as a low-cost light absorber for thin-film photovoltaic cells in virtue of its cheap raw materials, intrinsic p-type semiconductor and high absorption coefficient (10 4 cm −1) [, ].Thus, the CZTSe solar cell is potentially expected to yield high energy conversion at a lower cost [-].
