The nanoparticle product was isolated through centrifugation (Hamilton Bell v6500 Vanguard centrifuge, 6500 RPM for 4 minutes), then sequentially washed with water, ethanol, and acetone (20 mL of each) and dried in a dessicator
under low vacuum (approx.
The loaded filters were heated at a temperature of 300[degrees]C for 8 hours and kept in a dessicator
The grounded material was placed in a muffle furnace at 500[degrees]C for 3 hr and resulted activated carbon (CC) was screened using a sieve shaker for 30 minutes then different sized particle mixtures were collected separately from the sieve analysis and stored in a dessicator
for further use.
The resulting brownish-grey coloured crystals formed was filtered and dried over a silica gel in a dessicator
The dried slices were allowed to cool for about 30 minutes in a dessicator
prior to analysis .
Then, samples were dried at 100[degrees]C for at least 4 h and crucibles were weighed after cooling in a dessicator
. The undigested residues were then collected in a filtration unit (Fibertee System M, Tecator, Sweden) by using dried and pre-weighed glass filter crucibles (d: 3 cm; pore size: 40-90 pm) containing about 0.5 g celite (545, Tecator) as a filter aid.
Aluminum weigh boats (43mm diameter by 12mm high) were pre-dried 4 hours at 120[degrees]C and stored in a dessicator
jar until used.
Coated specimens were rinsed, drained, and dried in cool air and finally stored in a dessicator
(79) After fresh venom is collected it is chemically dried in a dessicator
under vacuum, where it forms into crystals.
Fluoride stock solution (1000 [micro]g [ml.sup.-1]) was prepared from sodium fluoride (NaF; USP reference standard which was dried for 4 hours at 150[degrees]C and then cooled in a dessicator
The ratios of X-ray basal first-order reflection intensities of the 14 [Angstrom] phyllosilicates obtained from variously treated oriented samples of the <4 [micro]m fractions separated from recent bottom sediments [[Mg.sup.2+]-saturated sample dried in air and vapour glycolated; [K.sup.+]-saturated sample dried in air (54 % relative humidity), and vapour glycolated, and then hydrated above water in a dessicator
for 72 hours] are a result not only of different rock-soil sources but also of their transport history.
After conditioning, each board was cut to yield 10 2- by 2-inch (5.08 by 5.08-cm) specimens for tensile strength perpendicular to the face (IB), eight 2.75- by 5-inch (6.99 by 12.7-cm) dessicator
samples, and four 6- by 6-inch (15.24 by 15.24-cm) dimensional stability specimens (thickness swell).
