Abstract The cationic polymerization of 3,3‐bis(azidomethyl)oxetane (BAMO) was compared with the polymerization of 3,3‐bis(chloromethyl)oxetane (BCMO). The initiating system, boron trifluoride diethyl etherate/diethylene glycol (system. name: 2,2′‐oxydiethanol) was used and it was shown that unusually high concentrati…

A systematic experimental and theoretical study of first-order grating coupling to surface plasma waves existing at an air–Ag interface is presented. The experiment extends beyond previous work to grating depths comparable with the grating period. The grating profiles range from sinusoidal to rectangular. For TM-polar…

The durability of three ceramic waste forms containing Zr as a constituent is examined at 90° and 150°C in HCl or deionized water. The three ceramic waste forms examined are: (A) 10‐mol%‐Y 2 O 3 ‐stabilized ZrO 2 , (B) La 2 Zr 2 O 7 with a pyrochlore structure, and (C) CaZrO 3 with a perovskite structure. Each form co…

Discusses reduction of thread strength as a cause of loading in sewing. Investigates measurements of dynamic loads of the thread during seam formation and reduction of thread strength after loading in sewing. Analysis of results shows that the reduction in thread strength after loading in sewing is a function of dynam…

Complete active space multiconfiguration self-consistent field followed by higher-order configuration interaction calculations reveal that the ground state of Au6 is of 1A1 symmetry with a capped pentagonal structure. Similar calculations on Au−6 are also made. The 1A1g state of the neutral Au6 with a ring structure (…

A new method of pulse sharpening is described in which the risetime of a high-voltage pulse is progressively reduced as it propagates along a uniform lumped-element delay line containing nonlinear ferroelectric capacitors. The capacitors are made from a barium-titanate-based ceramic dielectric whose relative permittiv…
