AFM has also been used to measure, in an aqueous environment, the dispersion force due to polymer adsorbed on the substrate. [17] Forces of the order of a few piconewtons can now be routinely measured with a vertical distance resolution of better than 0.1 nanometers. Force spectroscopy can be performed with either static or dynamic modes.
DFM Engineering is an American telescope and optics manufacturer founded in 1979 by Frank Melsheimer in Longmont, Colorado. [1] [2] DFM makes medium size Cassegrain telescopes and their associated systems including telescope optics, control systems, and mounts. A range of pre-designed telescopes are made, as are various custom installations.
Design for manufacturability (also sometimes known as design for manufacturing or DFM) is the general engineering practice of designing products in such a way that they are easy to manufacture. The concept exists in almost all engineering disciplines, but the implementation differs widely depending on the manufacturing technology.

Fire-ravaged Southern California faces an unprecedented “extreme fire risk” Tuesday with the return of powerful Santa Ana winds — which may reach up to 75 mph, forecasters warned.
The instrumentation involved for pc-AFM is very similar to that necessary for traditional AFM or the modified conductive AFM. The main difference between pc-AFM and other types of AFM instruments is the illumination source that is focused through the inverted microscope objective and the neutral density filter that is positioned adjacent to the illumination source.
Wind gusts and dry conditions will linger throughout the day on Thursday in Los Angeles where firefighters hope to gain on their momentum against two major wildfires that have ravaged everything ...
