Reb or REB may refer to:
Reb (/ˈrɛb/, Yiddish: רב) is a Yiddish honorific traditionally used for Orthodox Jewish men. It is not a rabbinic title; it is the equivalent of the English "mister". In writing it is abbreviated as ר׳. It may also be a short form of Rebbe.
The title was adopted by Orthodox Jews at the time of the schism with the Karaites, as a sign of loyalty to Rabbinic Judaism.
When addressing someone directly, Reb is usually used with the first name only ("May I help you, Reb Chaim?"). In other circumstances, it can be used with either the first name or the full name ("This is Reb Chaim Jacobs."; "Would you please help Reb Chaim?"). In formal written address, it is usually used along with the full name.
Rhenium diboride (ReB2) is a synthetic superhard material. It was first synthesized in 1962 and re-emerged recently due to hopes of achieving high hardness comparable to that of diamond. The reported ultrahigh hardness has been questioned, although this is a matter of definition as in the initial test rhenium diboride was able to scratch diamond.
The production method of this material does not involve high pressures as with other hard synthetic materials, such as cubic boron nitride, which makes production cheap. However, rhenium itself is an expensive metal.
The compound is formed from a mixture of rhenium, noted for its resistance to high pressure, and boron, which forms short, strong covalent bonds with rhenium.
ReB2 can be synthesized by at least three different methods at standard atmospheric pressure: solid-state metathesis, melting in an electric arc, and direct heating of the elements.
In the metathesis reaction, rhenium trichloride and magnesium diboride are mixed and heated in an inert atmosphere and the magnesium chloride byproduct is washed away. Excess boron is needed to prevent formation of other phases such as Re7B3 and Re3B.
I will clean and cover my windows
'Cos I don't want to see where the wind blows
I'll love it, I'll covet another one's idol
Because I am the queen of denial
I'll love it, I'll love it
I'll love it, I'll love it
The ego is the master of psyche
And envy tastes sweeter than grey meat
I'll love it and learn to follow behind all
Because I am the king of denial
I'll love it, I'll love it
I'll love it, I'll love it
The back will snap from burdens of envy
And I'll forget the mould who set me
I'll love it, and shove it from proof to trial
Because I carry the weight of denial
I'll love it, I'll love it
I'll love it, I'll love it
