The calibrants are monodisperse polystyrene standards, Mw=580 to 3,220,000 from Polymer Laboratories. The universal calibration parameters are as follows: PS (K=0.0001280 and a=0.7120) and CE (K=0.00007572 and a=0.8424). The universal calibration parameters above were determined by light ...
Polystyrene cupsmake fun-sized containers for kids to grow small salad crops such as radishes. Pinch holes out at the base of the cup to make drainage holes Newspapercan be easily made into pots. Fold one page in half lengthways and roll it around a toilet roll tube so that the tube sti...
in raising pots prepared beforehand are taken out of the raising pots and cultivated in a storage tank 205 which is filled with culture solution, in which the storage tank 205 is fabricated of extraction method polystyrene foam and is capable of shielding the outside of the storage tank 205 ...
Also, polystyrene beads were partially aggregated due to the hydrophobic effect although the flow velocity was not significantly influenced by this phenomenon because the size of the microchannel was much larger than the size of the beads. In addition, only liquid would be used in most of practica...
were harvested from wild plants along the shoreline in Mola di Bari. Ascorbic acid at 40 mM was used as pre-treatment to improve sea fennel seed germination, according to the procedure described by Meot-Duros and Magné [23]. The seedlings were produced in polystyrene plug trays (160 cells ...
The seeds (cca. 80 seeds/cross) obtained from the twisted dried capsules were sown in October 2013 in Plants 2020, 9, 160 13 of 19 polystyrene boxes with standard sowing substrates. The boxes were kept at 26 ◦C with a high relative humidity of 98% in the greenhouse. After two ...
