Figure 2From: Fabrication, characterization, and thermal property evaluation of silver nanofluidsUV absorption spectrum during formation of Ag + PVP nanofluids and absorption spectrum of W3 after storage. (A) UV adsorption during the formation of Ag + PVP nanofluids (W0, W1, W2, W3. and W4 at before and after 20, 40, 60, and 90 s MW irradiation times) was on the traces. (B) Absorption spectrum of W3 after storage for 2 and 6 months at room temperature.Back to article page
