Plastic can be as glossy as glass but, unlike glass, it is hydrophobic – it repels water. If water does not flow smoothly over the surface, the mirroring chemicals will not deposit evenly. There are two ways to overcome this problem: You can flood the surface with so much water (or mirroring chemicals) that the beads merge into a smooth sheet. This technique works best using our mirror bath technique where the object to be mirrored is submerged in the chemicals. It is only practical for small objects. You can use a wetting agent (a type of surfactant) to break the surface tension on the plastic before you apply the mirroring chemicals. There are many types of plastic and each type has its own chemistry and surface characteristics. We have tested our Wetting Agent on some types of acrylic, polycarbonate and polyurethane. We have not tested it on all types of plastic. You should test it on a sample of your substrate to confirm that it works. See Cleaning and Polishing for more information on wetting agents.

My takeaway lesson was that the safest strategy was to divulge my results only after they were accepted for publication. And I’m sure I’m not the only one who feels this way. Science is too often a cutthroat venture, with publications as the currency for measuring one’s success. But with everyone keeping their findings secret until they have been approved by the peer-review process, aren’t we slowing the course of scientific discovery?

Scientists have failed to establish clear mores for crediting discoveries

Many believe that false attribution is actually increasing in frequency, likely motivated by the steady decrease in grant-funding rates.

Bending the fiber in one direction leads to a better transmission whereas bending in the other direction leads to a lower transmission, compared to the straight position.

Plastic optical fiber can also be used for seat-occupancy recognition

One approach for seat-occupancy recognition is the Kinotex cavity sensor from Canpolar East (St. John’s, NF, Canada).

how to deal with recommendations for objects whose value diminishes with the number of people who use it.

Clearly the resulting distribution of these different types of particles is entirely different.

The analogy here is with goods that any number of people can share or that only one person can have.
