Interfacing, also known as stabilizer, is a light piece of fabric that is sewn or fused onto fabric pieces that need an added stiffness. You would commonly use interfacing for collars, cuffs or on the facing of a shirt or jacket.
Photons of light photoexcite pigment molecules in the antenna complex. Energy from each photon is transferred to an electron, causing an excited state.hotosystem I (PSI) is an integral membrane protein complex that uses light energy to mediate electron transfer from plastocyanin to ferredoxin. The PS I system comprises more than 110 co-factors, significantly more than photosystem II. These various components have a wide range of functions.
A patch antenna (also known as a rectangular microstrip antenna) is a type of radio antenna with a low profile, which can be mounted on a flat surface.It consists of a flat rectangular sheet or patch of metal, mounted over a larger sheet of metal called a ground plane.he impedance bandwidth of a patch antenna is strongly influenced by the spacing between the patch and the ground plane. As the patch is moved closer to the ground plane, less energy is radiated and more energy is stored in the patch capacitance and inductance: that is, the quality factor Q of the antenna increases.
