Simple A tunable and transparent metamaterial absorber (MMA) with a water-based substrate is presented, with high optical transparency and broadband microwave absorptivity. In the material structure, indium–tin–oxide (ITO) films are included as the resonant pattern and reflective layers, and distilled water … Formaldehyde (/ f ə r ˈ m æ l d ə h aɪ d / fer-mal-duh-hahyd, also / f ɔːr ˈ m æ l d ə h aɪ d / for-) (systematic name methanal) is a naturally occurring organic compound with the formula CH 2 O (H−CHO). The pure compound is a pungent-smelling colourless gas that polymerises spontaneously into paraformaldehyde (refer to section Forms below), hence it is stored as an aqueous Water (H 2 O) is a transparent, tasteless, odorless, and almost colorless chemical substance and covers over 70% of Earth's surface. No known life can live without it.. Lakes, oceans, seas, and rivers are made of water. Precipitation is water that falls from clouds in the sky.It may be rain (liquid) if it is warm, or it may be frozen if it is cold.
