1. One way to reduce health care costs is to reduce the demand for health care services. This can be accomplished by teaching employees to make better decisions about when they should see the health care provider or go to the emergency department ver

The feasibility of microcantilever‐based optical detection is demonstrated. Microcantilevers may provide a simple means for developing single‐element and multielement infrared sensors that are smaller, more sensitive, and lower in cost than quant

Laser-induced fluorescence has been applied to the nondestructive inspection of graphite-fiber-reinforced polymer-matrix composites. Upon curing, the epoxy resin in these materials forms a highly cross-linked network of aromatic sub-units. This resul

Since the discovery of the surface-enhanced Raman scattering (SERS) effect, numerous substrate designs have been proposed for a variety of analytical applications. Although many of these have offered exceptional electromagnetic enhancement, the durab

The ESTM can be operated in air, but does well at this stage of development to obtain 2-nm lateral resolution on even a thin layer of an electrically insulating sample place on a conducting substrate. In fact, subatomic resolution is thus far limited

Tunneling of either electrons or photons from a sample to a probe tip yields an exponential signal that permits subwavelenght tangential resolution and even better resolution of the tip-to-sample distance. PSTM provides images of both insulators and

Oscillating silicon nitride microcantilevers coated with a thin gold film have been used to detect mercury vapor in air. Cantilever resonance frequency changes due to surface mass loading as a result of adsorption of mercury vapor. Furthermore, canti

The resolution limit in an atomic force microscope image usually is attributed to the finite radius of the contacting probe. Here, it is shown that this assumption is valid only when adhesion forces are minimal. Relative to the tip‐imposed geometri
