Sticky tape

The AiRTRACE system was mounted on either a fixed wing or heiicopter equipped with aerodynes that ingested airborne particies and concentrated this dust on sticky tape that was inside the aircraft. The tape was advanced to a dean position for every five seconds of flight and a record number piaced on the tape and the flight path camera fiim so that the iocation of the dust spot couid be iocated on the ground. 

Zirconium propionate is a polymeric zirconium carboxylate its structure is illustrated in Fig. 10. Use of zirconium propionate markedly increases the adhesion of an ink applied to treated polypropylene film. Figure 11 compares zirconium propionate with titanium acetylacetonate, which is commonly regarded as the industry standard. The standard test method used in the ink industry is the so-called tape test . Sticky tape is placed on the printed film and pressure is applied by the operator s thumb. The tape is then pulled off, by hand, and the amount of ink removed is visually assessed. Although extremely crude, it can be, and is, used for control in the ink industry. 

There are numerous ways to prepare a solid sample for XPS-analysis 17K Because of the 360° angle of acceptance, the optimum sample geometry is a cylinder of 11 mm diameter and 2 mm width. However, with a certain loss in sensitivity, flat samples as well as odd shaped samples can be analyzed as well, if they do not exceed the maximum size defined by the vacuum interlock. Sample powders are normally mounted on sticky tape or pressed into a metal grid 17). Excellent results were also obtained by pressing pellets 31) or by subliming the sample directly unto the sample holder. 

Evidence to support the idea that sensitive skin has a thinner stratum corneum is an experiment using stripping and TEWL. Stripping of the stratum corneum was done by the application of sticky tape and its removal. Sticky tape was applied and removed, taking the upper layers of the stratum corneum. Each time this was done, the TEWL was measured. The average number of tape... 

A second piece of evidence is offered by Frei (7-9) who studied surface debris that was removed from the Shroud with sticky tape. Among the collected materials, he observed and identified pollen from plants that are uniquely indigenous to Palestine and Anatolia (10). Some conclude from these observations that the Shroud originated in the Middle East and was subsequently brought to Europe via Constantinople (4). But we consider it just as likely that the Shroud was produced in Europe and subsequently transported to Palestine, perhaps on one of the Crusades, where it was exposed to the local pollen rain. 

In a more definitive sense, examinations of samples taken on sticky tape (12,13) have shown that the color of the yellow fibrils does not arise from any inorganic pigments (12). Both oxidative and reductive reversal of color back to new -linen white readily demonstrates that the color of the fibrils cannot be due to the presence of iron oxides. Thus the body-only image is due solely to the distribution of the yellow fibrils. 

Microscopic Characteristics. At magnifications of250 X to 1000 X, the fibrils in the blood areas are clearly coated. Joints of the linen fibril are filled with some substance. Samples of ca. 300-year-old Spanish linen were treated with partially clotted blood and allowed to sit for 18 months (11,12). Microscopic samples of this treated linen made with sticky tape in the same manner as the Shroud samples appeared to be very similar to the Shroud samples. Amorphous globs colored orange to orange-red to yellow to yellow-red were observed in the Shroud samples and appeared similar to those from samples taken from such treated linen. In other words, microscopically the Shroud samples taken from the blood areas looked like blood as seen on a simulacrum (12). 

It is important to note that there are also charred linen fibrils, body-only image fibrils, blood particulates, globs, and shards occasionally present on these off-image areas. To our mind, this observation is best explained by the translocation mechanism referred to earlier. This explanation was proposed by Jackson et al. (J7) who attribute numerous foldings of the cloth as the most dominant mechanism. There appear to be at least four distinct fold patterns that are identifiable in the permanent-fold patterns that are on the Shroud. Jackson performed an experiment in which he deposited ferric oxide in locations corresponding to the blood images on the Shroud on a clean piece of cloth of the dimensions of the Shroud. After just four foldings he took sticky tape... 

For SEM examination the same amount of the starting suspension was filtered on a polycarbonate filter, 0.2 /am pore size and 25 mm diameter, placed on a backing cellulosic filter of 1.2 /am pore size, in order to facilitate a more uniform distribution of particles on the filter. A small portion of the particles-laden filter was then mounted on SEM stubs by double sided sticky tape and then coated by gold of about 300 nm thick in a sputter coater [11]. 

To avoid displacement of the particles during SFM imaging, they have to adhere properly on the supporting surface. One possibility is to disperse them by air flow on sticky tapes (Tesa, doublesided, Beiersdorf). Because the adhesive polymer matrix of the tape covers the particles after one day of storage, images have to be taken only on freshly prepared samples. 

Double-sided sticky tapes are popular for the attachment of samples. Various brands and types are available. For many routine measurements conventional tape is sufficient however, some thicker variants may lead to problems when pressure is exerted to fix the samples, since the tape will relax and hence cause substantial drift in the AFM image. A similar effect may be present as a result of thermal expansion, when a cold AFM is operated with high resolution in the first hour(s)... 

The AFM is set up for a standard CM experiment (Sect. 3.2.2). To be able to address the morphology and roughness on various lateral length scales, a large area scanner is selected. After the sample (film firmly attached to the sample puck with double sided sticky tape) has been mounted, care has to be taken to note the relative orientation of cantilever and characteristic film directions (e.g. the machine direction). 

Thin films with a thickness of 50 pm of a commercially available PS-PB-PS triblock copolymer (e.g. from BASF, 74% PS, 26% PB) are prepared by solution casting from a 3% solution in toluene onto TEFLON -foil, which is placed in a precleaned petri-dish. The solvent is slowly evaporated over a period of 2 weeks. Residual solvent is then removed and films are annealed under reduced pressure in a vacuum oven at 120°C (48 h). Finally, the films are removed from the support and are uniaxially stretched at a constant strain rate of 0.1 s 1 beyond the yield point at room temperature. ARM investigations are carried out on prestretched samples that are mechanically clamped or fixated by double-sided sticky tape onto the AFM sample holder.
