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 ]
In organic chemistry, a cross-coupling reaction is a reaction where two different fragments are joined. Cross-couplings are a subset of the more general coupling reactions. Often cross-coupling reactions require metal catalyst
The symmetry group of a biaxial nematic is i.e. that of a rectangular right parallelepiped, having 3 orthogonal axes and three orthogonal mirror planes. In a frame co-aligned with optical axes the second rank order parameter tensor , the so-called Q tensor of a biaxial nematic has the form [ citation needed ]
Prolate spheroidal coordinates μ and ν for a = 1.The lines of equal values of μ and ν are shown on the xz-plane, i.e. for φ = 0.The surfaces of constant μ and ν are obtained by rotation about the z-axis, so that the diagram is valid for any plane containing the z-axis: i.e. for any φ.
These were bright, spicy brews made from fermenting ginger root until they reached 2–3% alcohol. “Most ginger beers have less than 0.5% alcohol, which is how they're classified as non ...
This well-rounded kimchi rice bowl is packed with fiber and probiotic foods like kimchi and yogurt to support a healthy gut. Prebiotic foods like edamame and garlic add flavor and additional gut ...
Sportscaster Charissa Thompson got her groove on at Taylor Swift's Eras Tour earlier this year, and the pop star's father was there to see it all.
