چکیده

Magnesium chloride hexahydrate and magnesium nitrate were tested for their thermal energy storage in a mixture with carbon materials. The graphite, graphene zeolite-templated replicas used as nucleating agent to supress supercooling. addition of any type into did not lead decrease the supercooling significant enthalpy fusion crystallisation was observed. mixtures after cycling apparently wet, indicating that some dissolved its structural water. In case hexahydrate, zeolite beta, mordenite or faujasite Nevertheless, graphite provided highest suppression from about 30 2.2 K within fifty cycles. conductivity measurement pressed tablets materials at 2 MPa showed increase 9% 15% 3 mass% respectively. Mixing improved heat transfer significantly reduced unwanted supercooling, which is necessary use accumulation.

Magnesium bis(monoperoxyphthalate) hexahydrate as mild and efficient oxidant for the synthesis of selenones

A new, efficient and mild method for the direct oxidation of selenides to selenones using magnesium bis(monoperoxyphthalate) hexahydrate (MMPP) has been developed. Noteworthy this transformation proceeds at room temperature, employs a cheap and safety oxidant and has a broad functional group tolerance. Moreover, the produced selenones could be useful intermediates for the synthesis of different...

Cadmium sulfite hexahydrate revisited

The present structural revision of the title compound, tetra-cadmium tetra-sulfite hexa-hydrate, [Cd(4)(SO(3))(4)(H(2)O)(5)]·H(2)O, is a low-temperature upgrade (T = 100 K and R = 0.017) of the original room-temperature structure reported by Kiers & Vos [Cryst. Struct. Commun. (1978). 7, 399-403; T = 293 K and R = 0.080). The compound is a three-dimensional polymer with four independent cadmium...

Axillary hyperhidrosis - topical treatment with aluminium chloride hexahydrate.

Forty-two patients with axillary hyperhidrosis on the waiting list for surgery were treated with topical saturated solution of aluminium chloride hexahydrate in absolute alcohol. There have been 7 failures. Three patients were unable to cope with the treatment and 4 more experienced severe local irritation or soreness; these 4 were submitted to local surgery. This is a simple and effective trea...

Temperature Dependence Studies of 3 CI NQR Frequencies in Magnesium and Nickel Hexachlorotellurate(IV) Hexahydrates and Nickel Hexachloroiridate(IV) Hexahydrate*

The C1 NQR frequencies in MgTeCl6 • 6 H 2 0 , NiTeCl6 • 6 H 2 0 , and NiIrCl6 • 6 H 2 0 have been determined at various temperatures. These compounds form rhombohedral crystals with the space group R3, showing a single resonance line. The C1 NQR frequencies of the Te(IV) complexes exhibit an unusual positive temperature coefficient. The deuterated analogs of the Te(IV) complexes show a small fr...
