  2. Chemical force microscopy - Wikipedia

    en.wikipedia.org/wiki/Chemical_force_microscopy

    As stated earlier, the force resolution of CFM does allow one to probe individual bonds of even the weakest variety, but tip curvature typically prevents this. Using Eq 2, a radius of curvature ⁠ ⁠ < 10 nm has been determined as the requirement to conduct tensile testing of individual linear moieties. [2]

  3. Gravity Probe B - Wikipedia

    en.wikipedia.org/wiki/Gravity_Probe_B

    Gravity Probe B (GP-B) was a satellite-based experiment to test two unverified predictions of general relativity: the geodetic effect and frame-dragging. This was to be accomplished by measuring, very precisely, tiny changes in the direction of spin of four gyroscopes contained in an Earth-orbiting satellite at 650 km (400 mi) of altitude ...

    en.wikipedia.org/wiki/Chemotaxis_assay

    Some capillary techniques provide also a chamber like arrangement, however, there is no filter between the cells and the test substance. [5] Quantitative results are gained by the multiwell type of this probe using 4-8-12-channel pipettes. Accuracy of the pipette and increased number of the parallel running samples is the great advantage of ...

    en.wikipedia.org/wiki/Scanning_vibrating...

    Scanning vibrating electrode technique was originally introduced to sensitively measure extracellular currents by Jaffe and Nuccitelli in 1974. [1] Jaffe and Nuccitelli then demonstrated the ability of the technique through the measurement of the extracellular currents involved with amputated and re-generating newt limbs, [5] developmental currents of chick embryos, [6] and the electrical ...

  6. Frame-dragging - Wikipedia

    en.wikipedia.org/wiki/Frame-dragging

    The Gravity Probe B experiment [20] [21] was a satellite-based mission by a Stanford group and NASA, used to experimentally measure another gravitomagnetic effect, the Schiff precession of a gyroscope, [22] [23] [24] to an expected 1% accuracy or better. Unfortunately such accuracy was not achieved.

    While no experiment has ever precisely duplicated the Mars LR test and control results, experiments with hydrogen peroxide-saturated titanium dioxide have produced similar results. [ 45 ] While the majority of astrobiologists still conclude that the Viking biological experiments were inconclusive or negative, Gilbert Levin is not alone in ...
