Figure Lengend Snippet: a Effect of the c-IPN cathode on the specific energy of cells (excluding packaging substances) and the specific capacity of electrode active materials ( C sp ) of NCM811 as a function of the areal-mass-loading ( M / A ). b Photograph of the double-stacked pouch-type cell (area = 34 × 34 (mm × mm)), in which the c-IPN cathode ( C/A = 18 mAh cm –2 ) was coupled with a Li-metal anode (20 mAh cm –2 , negative to positive electrode capacity ratio ( N / P ) of 1.1) under a limited amount (electrolyte mass/cell capacity ( E / C ) ratio of 2.5 g Ah –1 ) of carbonate-based liquid electrolyte). c X-ray microtomography image showing the cross-sectional structure of the double-stacked pouch cell. d Cycling performance of the double-stacked pouch-type cell at a charge/discharge current density of 0.9 mA cm –2 /1.8 mA cm –2 and a voltage range of 3.0–4.4 V at 25 °C.

Article Snippet: The internal structure of the pouch-type cell was characterized using X-ray microtomography (Xradia 520 Versa, Carl Zeiss Inc.).

(C) Double-fluorescence bone labeling by calcein (green) and alizarin complexone (red). Scale bar, 100 μm. (D) Quantification of mineral apposition rate (MAR) from bone labeling images. (E) Quantification of bone formation rate (BFR/BS) from bone labeling images. n = 5. (F) Reconstructed microCT images of L4 vertebra. Scale bar, 500 μm. (G to J) Quantification of microCT images. (G) BMD. (H) BV/TV. (I) Tb.N. (J) Tb.Sp. n = 5. Mechanical measurement for (K) maximum load and (L) stiffness of tibia. n = 12. OV, ovariectomy, vehicle [dimethyl sulfoxide (DMSO)]; OB, ovariectomy, BAY 60-6583 (1 mg/kg). * P < 0.05, ** P < 0.01, *** P < 0.001.

Article Snippet: The reconstruction of scanned images was performed using microCT Evaluation Program V6.6 (Scanco Medical), followed by generation of radiographs and three-dimensional models using microCT Ray V4.0 (Scanco Medical).
