Capsule immersed

Asymmetrical membrane capsules were prepared, for example, by dip coating mandrels with solutions containing 15 wt% CA and 33 wt% ethanol in acetone. After the mandrels were withdrawn from the coating solution they were immersed in water to precipitate the polymer and create the asymmetrical membrane capsule shell. This process was used to create both the body and the cap for the capsules. The capsules were sealed at the juncture between the cap and body by banding with a solution of CA in acetone. 

Figure 7. Release profile from sonicated capsules. Samples that were to be treated with sonic energy were placed in the polypropylene cages and immersed in 10 ml of physiological saline in scintillation vials. The vials were subjected to 3 minutes of sonication at 4 C in a sonic bath. The capsules were then transferred to fresh buffer and the release of myoglobin was followed (- -) and compared with release from capsules containing free myoglobin (-x-).

Experiments were performed using capsules with membranes made of covalently linked human serum albumin (HSA) and alginate [7, 8], Details are given in [4], Figure 2 shows the evolution of a capsule after removal at time I, 0 from a solution of NaCl at 11 g/1 and immersion in a solution at 3.5 g/1. The experimental results fit well to a single exponential, leading to an estimate for D [3],... 

In a spray-drying method of encapsulation, Zhao and Whistler (1994) suspended starch to a concentration of 30% in water containing 0.1-1.0% gelatin or any of a number of polysaccharide bonding agents the suspension was forced through an orifice (2 mm diameter) under 80-100 psig at an inlet temperature of 120°C and outlet temperature of 76°C. Porous 10-40-nm-diameter spherical capsules were obtained that were then immersed in peppermint oil. After diffusion of the peppermint oil into the capsules, the spheres were rinsed free of oil and coated in a fluidized bed with a 3%... 

This allows us to derive the elastic properties of the capsules from the measured shell spring constants. The most precise way to do so is to use the combination of the data in Fig. 3, since the slope of the rescaled data contains the Young s modulus of the material and is an average over all measurements. However, since the measurements were carried out in water and not in dried state, like the thickness measurements, the thickness has to be modified to account for the swelling of PAH/PSS. Kiigler et al. showed that the thickness of the multilayers depends on the degree of humidity [27]. According to their study, PAH/PSS multilayers swell by 15% between multilayers dried under ambient conditions and immersed into water. Similar results were found by Losche et al. [28], who... 

For the first twenty minutes or so of the experience I felt considerable fear. I felt myself lowering down into a softer and more vulnerable place. I could feel the layers of fear peeling off of my torso and moving away into space. I felt immersed in fear for a time. Soon after ingesting the second capsule, I dropped below the fear and contacted a warm and supportive baseline feeling, a space of support that was totally without fear. This gave me my first sense of what it is like to not be a paranoid, to be like other people. 

Analysis of the oxyfluoride for osmium and fluorine followed alkaline hydrol3rsis in a closed vessel. A sealed longnecked capsule, containing the sample, was broken by turning a stopcock, into the hore of which, the neck of the capsule extended. The capsule was wholly immersed in aqueous alkali. Osmium was determined by reduction to the metal with hydrazine hydrate.Fluorine was estimated by the Willard and Winter distillation followed hy precipitation of fluoride as PbClF. Fluorine was also determined in the filtrate following the osmium precipitation (Found F, 31T Os, 61-9, F,OOs requires F, 31-5 O, 5-4 Os, 63-1%). 

Suppose 2.88 X 10 mol of Br2(f) is sealed in a glass capsule that is then immersed in a solution containing excess NaOH(itq ). The capsule is broken, the mixture is stirred, and a measured 121.3 J of heat evolves. In a separate experiment, simply breaking an empty capsule and stirring the solution in the same way evolves 2.34 J of heat. Compute the heat evolved as 1.00 mol Bt2(f) dissolves in excess NaOH( < ). 

The polymerization kinetics were studied via time-conversion relationships at different dose rates (Figures 6-9). The radiation curing was carried out at room temperature in closed aluminum capsules. Percent monomer conversion was determined gravimetrically for N-vinylpyrrolidone. Evaporation was accomplished under vacuum in a ventilated oven at 50 °C until the weight was constant. For butyl methacrylate and polyester resins, the residual monomer content was determined by gas chromatographic analysis after immersion of the cured products in acetone. 

In this experimental section, the production of polysulfone microcapsules containing vanillin is described. Our method is based on the phase inversion by immersion precipitation technique. The herein described process has been successfully employed for the encapsulation of vanillin into polysulfone microcapsules and, in addition, vanillin release from those capsules has been characterized. Polysulfone/vanillin microcapsules could have an application in laundry industry and also in medical applications. ... 

An attempt to use a recently patented concept (Dispersed Nano-Objects Protective Encapsulation—DOPE process) intended to disperse carbon nanotubes in polymeric matrices was reported. Physically cross-linked alginate capsules were successfully formed in the presence of either cellulose whiskers or microfibrillated cellulose [153]. The resulting capsules were extruded with a thermoplastic material. Another possible processing technique of nanocomposites using cellu-losic nanoparticles in the dry state present in the filtration of the aqueous suspension to obtain a film or dried mat of particles followed by immersion in a...

For specimens which comprise or simulate radioactive material enclosed in a sealed capsule, either a leaching assessment as required in para. 711(a) or one of the volumetric leakage assessment methods as specified in para. 711(b) should be applied. The leaching assessment is similar to the method applied to indispersible solid material (see para. 710), except that the specimen is not initially immersed in water for seven days. The other steps, however, remain the same. 

For some products the USP/EP/JP rotating basket apparatus (Figure 2) may be more appropriate for example, in the case of floating capsules and granules. Operation of the basket apparatus is similar to that of the paddle apparatus, except that the basket containing the dosage form is immersed in the dissolution medium prior to starting the rotation. 

The two coupons in the glass capsules did not show any change in appearance even after 1374 days of immersion. This gave further evidence that corrosion can be prevented in high purity water.
