An accelerometer was announced that used infrared light to measure the change in distance between two micromirrors in a Fabry–Perot cavity. The proof mass is a single silicon crystal with a mass of 10–20 mg, suspended from the first mirror using flexible 1.5 μm-thick silicon nitride (Si 3 N 4) beams. The suspension allows the proof mass to ...
Orthogonal tandem catalysis is a "one-pot reaction in which sequential catalytic processes occur through two or more functionally distinct, and preferably non-interfering, catalytic cycles". [7] This technique has been deployed in tandem alkane-dehydrogenation-olefin-metathesis catalysis [ 8 ] [ 9 ]
The LN-3-2B is the Inertial Navigation System used in the Canadian CF-104. [12] The LN-3-13 is fitted to the Italian F-104S/CI and F-104S/CB; [13] enhanced variants of the F-104G from 1969 and onward. In the early 1980s a further upgrade led to the F-104S ASA version which kept the original LN-3; but the ASA-M version of the '90s was equipped ...
These combinations are chosen to satisfy two conditions. First, the total amount of s and p orbital contributions must be equivalent before and after hybridisation. Second, the hybrid orbitals must be orthogonal to each other. [27] [28] If two hybrid orbitals were not orthogonal, by definition they would have nonzero orbital overlap. Electrons ...
Directly below the accelerometer's geometry is a flex cavity that allows the mass in the cavity to flex or move in direction that is orthogonal to the surface of the accelerometer. Accelerometers based upon piezoelectricity are constructed with two piezoelectric transducers.

Example of a localized Wannier function of titanium in barium titanate (BaTiO3) Although, like localized molecular orbitals, Wannier functions can be chosen in many different ways, [3] the original, [1] simplest, and most common definition in solid-state physics is as follows.
U.S. Secretary of State Antony Blinken spoke with Israeli Defense Minister Yoav Gallant on Monday and urged further actions to substantially increase humanitarian aid in Gaza, the State Department ...
