The application of molecularly imprinted polymers (MIPs) as molecular scavengers for ambient plasma ionization mass spectrometry has been reported for the first time. MIPs were synthesized using methacrylic acid as functional monomer; nicotine, propyphenazone, or methylparaben as templates; ethylene glycol dimethacrylate as a cross-linker; and 2,2'-azobisisobutyronitrile as polymerization initi...

Platinum metals have long been used in the glass industry for crucibles and liners because of their high melting points and their chemical inertness to most molten glasses. Contamination of glass by platinum metals has not been reported except in one or two instances where the glasses had a high content of lead or barium. It is well known that heavy lead glasses are more susceptible to colourin...

MELTING UNDER VACUUM in an induction-heated crucible is a tried and tested process in the production of liquid metal. It has its origins in the middle of the 19th century, but the actual technical breakthrough occurred in the second half of the 20th century. Commercial vacuum induction melting (VIM) was developed in the early 1950s, having been stimulated by the need to produce superalloys cont...

The specific heat due to line nodes in the superconducting gap of YBa2Cu3O7 has been blurred up to now by magnetic terms of extrinsic origin, even for high quality crystals. We report the specific heat of a new single crystal grown in a non-corrosive BaZrO3 crucible, for which paramagnetic terms are reduced to ≈ 0.006% spin-1/2 per Cu atom. The contribution of line nodes shows up directly in th...

The author describes aspects of social contezct that are of importance in the genesis of murdmous aiolnnce in childrm and adolescents. Case presentations illustrate the effects of family attachmcnt pathology, diffning outcomes in destru,ctiae child,rm, and, the copycat phmommon. The author concludes by summarizing the continuum of responses of childrm and ad,obscmts to aarious forms of threat: ...
