- Retraction Watch noted that a recent paper in the Journal of Applied Polymer Science, "Drug release properties of poly(vinyl pyrrolidone)/acrylic acid copolymer hydrogels", was retracted as it was the third time that some of it had been published, a no-no if there ever one was. But I just wonder what the paper was REALLY about, since it had previously been published in places that I would never think to look for polymer research, the Arab Journal of Nuclear Sciences and Applications and also in Proceeding, 2nd International Conference on Radiation Sciences and Applications.
- Gene Quinn of the IPWatchdog blog (a blog I highly recommend for anyone with an interest in patents [*]) last week discussed some surprisingly short claims that appear in recent applications, such as
"Claim 1 from Application Serial No. 13/416,904:According to the application, symmetrically substituted 1,4-diaminobenzenes are easy to come by; it's the asymmetric ones that are the challenge. I can't say otherwise, but I think I would have expanded the claims to include asymmetrically substituted diaminonathphalenes, anthracenes, and other polycyclic aromatic hydrocarbons.
- Ninesights has a request for a "Reduced Cost and Complexity Heating Plate" which is a laugher. They want this new heatplate to
- Be applicable to plates between 5-10 inches in width and 10-20 inches in length
- Work with 15 Amp, 115 Volt power (20 Amp is acceptable but not preferred
- Provide uniform heat to the entire surface
- Reach 300 F in 3 seconds or less
- Be resistant to water, punctures and cutting by sharp objects
- Be integrated with a power controller/temperature regulator that maintains 300 F when significant heat drain loads are placed on the plates
- Presents a stainless steel surface
Walt Disney famously said "It's kind of fun to do the impossible", but this is not what he had in mind. The conservation of energy and these undergraduate level calculations are spoiling the fun of a "Major Equipment Supplier". Gee, maybe there really is a STEM shortage. There appears to be one at this company.
