Ethyl acetate acs reagent

In this work, a calendered bleached paper (Advantage MG White High Gloss, Mondi Group, Addlestone, UK) was used, with technical data shown in Table 1, supplied by Serchio Distribuzione (Roma, Italy). According to the technical sheet, the paper is obtained from a long-fiber sulphate pulp. Poly(hexano-6-lactone) (PCL) was purchased from Sigma Aldrich (Taufkirchen, Germany), having average Mw 80,000 g/mol, water content < 0.5%, and melt flow index (160 °C/5 kg) 2.01–4.03. Ethyl acetate (Ethyl acetate—ACS reagent, purity > 99.5%, Mw: 88.11 g/mol) and glycerol (1,2,3-Propanetriol, Glycerin, purity > 99.5%, Mw: 92.09 g/mol) were purchased from Sigma Aldrich (Taufkirchen, Germany). Potato starch (CAS-No 9005-84-9, analytical grade) was purchased from PanReac AppliChem ITW Reagents (Cinisello Balsamo, Milano, Italy); agar-agar was purchased from OXOID, Thermo Fisher Scientific (Rodano, Milano, Italy); polyethylene glycol (PEG) 200 (analytical grade, Density 1.124–1.126 g/cm³, Hydroxyl value: 535–590, Mw~190–210 g/mol; Fluka Analytical, Rodano, Milano, Italy) was used as a plasticizer.

The following chemicals were obtained from commercial suppliers and used as received: the polymer poly(d,l-lactic-co-glycolic acid) 50 : 50 (PLGA; M_W 38 000–54 000 Da, T_g 46–50 °C), under the commercial name of Resomer® RG 504 was purchased from Boehringer Ingelheim (Ingelheim, Germany) and Evonik Industries (Evonik Röhm GmbH, Germany). Sodium cholate, chloroauric acid (HAuCl₄·3H₂O), sodium citrate tribasic dehydrate ≥99.0% (Na₃C₆H₅O₇·2H₂O), PVA (polyvinyl alcohol) M_W 85 000–124 000 Da, 97–99% hydrolyzed, taurocholic acid sodium salt hydrate ≥95% (TLC), ethyl acetate ACS reagent, dodecanethiol, phosphotungstic acid hydrate as a contrast agent for microscopy and fluorescent molecule pyrene ≥99.0% were purchased from Sigma Aldrich (St Louis, MO, USA).
