Boron nitride (BN) has been deposited in situ on carbon fibers of 3D fibrous preforms by isopressure/isothermal chemical vapor infiltration (ICVI) from BCl 3 –NH 3 –H 2 mixtures, the aim being to produce a coating of uniform thickness in the whole preforms. The deposition temperature has been lowered to 773 K. Even at…

An analytical study was conducted to determine the feasibility of employing solar energy assisted thermoelectric (TE) cooling technology in automobile air conditioners. The study addressed two key issues—power requirements and availability of thermoelectric materials. In this paper, a mathematical model was developed…

This work investigates the intergranular corrosion of a sensitized Type 430 stainless steel in 1 N . Once the grain boundary groove is formed by dissolution of the Cr‐depleted material, a second form of localized corrosion commences within minutes and replaces the Cr‐depletion mechanism. The second‐mechanism attacks b…

Abstract Extensive surface‐enhanced Raman (SER) spectra of acridine and acridinium ions, taken as probes of DNA intercalating agents, were investigated in colloidal silver sols. From comparison of the SER and Fourier transform near‐IR Raman spectra, it is confirmed that acridine is adsorbed on the metal surface via it…

Abstract The energy balance model presented in Part I is applied here to data taken from the literature. Care was taken to choose well‐characterized systems to give a true test of the model's predictive character, rather than its ability to curve‐fit the data. The effects of concentration, particle size, strain rate,…

Abstract In a previous study, the mechanism of EPM peroxide vulcanization in the presence of various aromatic bis (allyl)esters was elucidated. It was concluded that the elastomer-coagent blend was phase separated and that during vulcanization chemical crosslinks are formed between the elastomer matrix and coagent dom…

Photoluminescence and thermoluminescence in BaSO4:Eu is reported. In earlier works, divalent Eu has been studied in BaSO4. In the present work Eu was incorporated as in predominantly Eu3+ or Eu2+ form. It is shown that RE3+ ↔ RE2+ conversion or RE2+ ↔ RE+ conversion is not an integral part of gamma induced TL. Eu3+ ↔…

The optical transmittance of pressureless sintered and of hot isostatically pressed (HIPed) mullite ceramics was studied in the near infrared (NIR), visible light (VIS), and the ultraviolet (UV) spectrum ranges. Both processing methods provided fine‐grained microstructures (mean grain size of 5–10 μm) with equiaxed gr…

A vibratory-type cavitation test rig was constructed to study the effect of polarizing currents applied to a cavitating body. The generation of gas by electrolysis reduced mechanical damage suffered by a cavitating body because of bubble collapse cushioning. However, the net effect on overall damage depended on severa…
