Abstract: The invention provides novel formulations comprising a stable inclusion complex of tributyrin and a cyclodextrin. In one particular embodiment, the formulation comprises an oven dried inclusion complex of tributyrin and ?-cyclodextrin that is effective in minimizing or preventing the unpleasant taste and odor of tributyrin, thus making it suitable for oral administration and delivery to the digestive tract and intestines. The invention provides compositions of these inclusion complexes and methods of using them that are advantageous as food, medicinal and other products, where the negative sensory properties of tributyrin can be a liability.

Abstract: A high precision micro/nanoscale machining system. A multi-axis movement machine provides relative movement along multiple axes between a workpiece and a tool holder. A cutting tool is disposed on a flexible cantilever held by the tool holder, the tool holder being movable to provide at least two of the axes to set the angle and distance of the cutting tool relative to the workpiece. A feedback control system uses measurement of deflection of the cantilever during cutting to maintain a desired cantilever deflection and hence a desired load on the cutting tool.
