Field Dependence of the Spin Relaxation Within a Film of Iron Oxide Nanocrystals Formed via Electrophoretic Deposition.

The thermal relaxation of macrospins in a strongly interacting thin film of spinel-phase iron oxide nanocrystals (NCs) is probed by vibrating sample magnetometry (VSM). Thin films are fabricated by depositing FeO/Fe(3)O(4) core-shell NCs by electrophoretic deposition (EPD), followed by sintering at 400°C. Sintering transforms the core-shell structure to a uniform spinel phase, which effectively increases the magnetic moment per NC.

Sacrificial layer electrophoretic deposition of free-standing multilayered nanoparticle films.

Sacrificial layer electrophoretic deposition (SLED) is a technique to assemble nanoparticles that yields free-standing, multilayered nanoparticle films with macroscopic lateral dimensions after the sacrificial layer is dissolved.

A clinical and immunologic study of workers with trimellitic-anhydride-induced immunologic lung disease after transfer to low exposure jobs.

The objective of the study was to determine the clinical and immunologic status of trimellitic anhydride (TMA) workers who have had immunologic lung diseases and who have been moved to lower exposure jobs. Twenty-nine consecutive workers with TMA-induced immunologic lung diseases who had been moved to low exposure jobs for more than 1 yr were studied retrospectively. Pulmonary symptoms were obtained by physician-administered questionnaire.

A clinical and immunologic study of employees in a facility manufacturing trimellitic anhydride.

We conducted a 1-year cross-sectional survey of 474 employees of a large chemical manufacturing complex to relate trimellitic anhydride (TMA) exposure to serologic and clinical outcomes. In 1988-1989, employees were evaluated by history and immunologic assay of total (T) and IgE antibody to trimellityl human serum albumin (TM-HSA). All employees were assigned to a TMA exposure class, from 1 (highest) to 5 (lowest), by an industrial hygienist, independent of the clinical and immunological data.
