This treatment is preferably conducted at a bath temp. about 50°C higher than the plating bath and at 0.5 to 50C/dm2 electricity quantity. A mixed molten salt of the chloride of the alloy component such as AlCl3 and MgCl2 and an inorg. chloride such as NaCl is then used to perform ...
Why does water boil at a higher temp then NH_3 when they are both dipoles? Why does the boiling point of liquids vary with altitude? Explain the trend in melting point of metals across period 3 elements. What is the effect of impurities on the melting and boiling points of a ...
Metal–organic frameworks (MOFs) are microporous materials with huge potential for chemical processes. Structural collapse at high pressure, and transitions to liquid states at high temperature, have recently been observed in the zeolitic imidazolate framework (ZIF) family of MOFs. Here, we show that...
