Pectin aerogels, with very low density (around 0.1 g cm) and high specific surface area (up to 600 m g), are excellent thermal insulation materials since their thermal conductivity is below that of air at ambient conditions (0.025 W m K).

Multistage fractionation of pine bark was performed using subcritical and supercritical CO at increasing pressures and temperatures. In total, seven fractions were collected, which demonstrated different enrichments of families of compounds. In particular, subcritical CO yielded 41% of the total extract in which unsaturated fatty acids represented the most abundant family.

Postchromatographic derivatization chambers for Thin Layer Chromatography (TLC) and its high-performance counterpart (HPTLC) are made of glass, which renders them fragile and - given their frequent use - eventually rather expensive. As a consequence, in daily lab routine, staining reagents are often kept in jars or beakers as cheap and available but unsatisfying equipment. This work describes the design and the manufacturing of shock-resistant and affordable dipping chambers from polypropylene (PP) by fused deposition modelling ("3D printing").
