AIR DATA PROBE CORROSION PROTECTION
A method can include vapor depositing a corrosion resistant coating to internal and external surfaces of a metallic air data probe. For example, vapor depositing can include using atomic layer deposition (ALD). The method can include placing the metallic air data probe in a vacuum chamber and evacuating the vacuum chamber before using vapor deposition. The corrosion resistant coating can be or include a ceramic coating. In certain embodiments, vapor depositing can include applying a first precursor, then applying a second precursor to the first precursor to form the ceramic coating.

There is provided a process for the preparation of composition in the form of a plurality of particles having a weight-, number-, and/or volume-based mean diameter that is between amount 10 nm and about 700 μm, which particles comprise: (a) solid cores, preferably comprising a biologically active agent; and (b) two or more sequentially applied, discrete layers, each of which comprises at least one separately applied coating material, and which two or more layers together surround, enclose and/or encapsulate said cores, which process comprises the sequential steps of: (1) applying an initial layer of at least one coating material to said solid cores by way of a gas phase deposition technique; (2) discharging the coated particles from the gas phase deposition reactor and subjecting the coated particles to agitation to disaggregate particle aggregates formed during step (1) by way of mechanical sieving technique; (3) reintroducing the disaggregated, coated particles from step (2) into the gas phase deposition reactor and applying a further layer of at least one coating material to the reintroduced particles; and (1) optionally repeating steps (2) and (3) one or more times to increase the total thickness of the at least one coating material that enclose(s) said solid core. The gas phase deposition technique is preferably atomic layer deposition. When the cores comprise biologically active agent, the compositions may provide for the delayed or sustained release of said active agent without a burst effect.

METAL COMPONENTS WITH INERT VAPOR PHASE COATING ON INTERNAL SURFACES
The invention provides metal liquid chromatography components with uniformly coated internal surfaces and methods for achieving the same. The invention addresses the problem of corrosion or interference of metal components in the flow path for LC analyses in which the sample interacts with metal ions or surfaces. The invention also alleviates the difficulties in coating very long metal tubes and very small metal channels with an inert, continuous coating that adheres well to metal surfaces. The metal flow path is rendered inert by the coating, and thus compatible with bioanalytical separations, for example, by using a vapor phase deposition process to coat the inner surfaces with a coating that continuously covers all metal surfaces in the flow path.
