An improved synthesis that could produce gram quantities of castasterone was proposed. The starting material was stigmasterol, the cyclic part of which was transformed in the first synthetic step into the 3α,5-cyclo-6-ketone. The side-chain carbon s

Methods of stereoselective synthesis of oxysterols are considered by the examples of (25R)-26-hydroxycholesterol, (24S)-24,25-epoxycholesterol, and (24S)-24-hydroxycholesterol containing functional groups in the terminal fragments of their side chain

The patch PIFA is an ideal compact antenna for wireless and sensing applications. It is usually fine-tuned, if not completely designed, by experimental methods because there is no accurate theoretical approach for the input impedance for all possible

A conventional patch antenna (PA) with its rectangular radiating sheet shorted to a ground plane along the zero potential line forms a rectangular planar inverted-F antenna (PIFA). The PIFA therefore can be considered as an effective compact antenna
