Soil Acidity and for Agronomic …

Even though materials are not the same, they all follow the same process to neutralize soil acidity. Lime supplies a surplus of the basic cations Ca 2+ and/or Mg 2+ in a carbonated, hydroxide, or oxide form (CaCO 3, MgCO 3, CaOH, MgOH, CaO).As the compounds dissolve in soil solution, the carbonate (CO 3 2-), hydroxyl (OH-), or oxide (O 2-) react with active acidity (H +) to form ...

In this work, a pyridine-based CTF (CTF-py, py = pyridine) derived from 2,6-dicyanopyridine is employed as a porous platform to anchor the Re carbonyl complex Re(CO) 3 Cl (Re-CTF-py), which exhibits high efficiency in the photocatalytic CO 2 reduction to CO with a turnover number (TON) of 4.8; the CO evolution rate for Re-CTF-py reached 353.05 μmol g −1 h −1 within 10 hours under full ...

A sound absorption panel containing coiled …

17.12.2020· A sound absorption panel with coiled Helmholtz resonators is proposed. The proposed structure offers a feasible possibility for absorbing undesired sound at low frequencies. The present structure lowers the working frequency and keeps all design attractiveness of Helmholtz resonators.

New collaboration to break ground — by …

29.10.2020· Symmetries have a profound effect on how waves — such as sound waves and light waves — propagate in natural and artificial materials. That's why scientists in an array of disciplines are working to understand symmetries and symmetry breaking in order to design new materials with exotic wave properties and develop new tools for wave manipulation.

Speech recognition with amplitude and …

Amplitude modulation (AM) and frequency modulation (FM) are commonly used in communication, but their relative contributions to speech recognition have not been fully explored. To bridge this gap, we derived slowly varying AM and FM from speech sounds and conducted listening tests using stimuli with different modulations in normal-hearing and cochlear-implant subjects.

Calciumoxid – Wikipedia

Calciumoxid, auch gebrannter Kalk, Branntkalk, ungelöschter Kalk, Kalkerde, Ätzkalk oder Freikalk, chemische Formel CaO, ist eine weiße kristalline Substanz, die mit Wasser unter starker Wärmeentwicklung reagiert.Bei dieser Reaktion wird Calciumhydroxid nach der Reaktionsgleichung + gebildet. Gebrannter Kalk wird in Weichbrannt-, Mittelbrannt-und Hartbranntkalk unterschieden.

Calcium oxide - Wikipedia

Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term " lime " connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate.
