Abstract: Certain metal surfaces are often unable to be effectively contacted with fluids containing hydrofluoric acid due to significant corrosion issues. Titanium and titanium alloy surfaces represent but one example. Corrosion inhibitor compositions comprising boric acid and an N-(phosphonoalkyl)iminodiacetic acid or any salt thereof can be used to suppress metal corrosion, including that taking place on titanium and titanium alloy surfaces.

Abstract: A system and method with increased sensitivity to microorganism growth. The system includes signal processing electronic circuit connected to a consumable or vessel through two or more electrodes that fully penetrate the vessel and are in contact with the fluid contents. The electronic circuit is configured to detect a component of the total impedance of the sample, specifically the “out-of-phase” or imaginary reactance component, which has a sensitive response to organism growth in a frequency-dependent manner. The system detects changes in both the composition of charged molecules in the liquid matrix and the number of microorganisms based on monitoring the sample for change in this parameter. This results in a 5-70% reduction in time-to-detection (TTD). The system and method detect organisms in a plurality of vessel shapes, volumes, and matrix (or media) formats. The electrodes are fully immersed in a continuous body of liquid sample.

Abstract: A substrate for electronic components is formed by bonding a cooling metal layer to one side of a ceramic tile and bonding an electronic metal layer to the other side of the electronic tile. The substrate is secured to a machining base and the cooling metal layer surface is enhanced through an MDT process. In the process, fins are sliced into the cooling metal layer with a tool to a depth of less than the cooling metal layer thickness. The slicing forces material upward without removing material from the cooling metal layer, forming fins that extend beyond the original thickness of the cooling metal layer. The fins can be cross-sliced at an angle to form pins.
