A B S T RA C T : Existing data on interatomic potentials have been used to study the interactions between an uncharged clay sheet and a water molecule. Calculations show that most of the clay surface is relatively hydrophobic, with binding energies for a water molecule in the range 1-0-4.5 kcal mo1-1 . There is, howev…

Abstract The ability of two representative oxisols from the Cerrado region of Brazil to adsorb Ca 2+ and SO 2‐ 4 , when in their natural acidic state, was determined by using dissolved CaCl 2 , K 2 SO 4 and CaSO 4 salts as adsorbates. Calcium adsorption from CaCl 2 and CaSO 4 was nearly linearly dependent on the equil…

F.t.i.r. spectroscopy has been used for the study of dehydration of heteropolyacids (HPA) of the series H3+xPMo12–xVxO40 carried out in vacuo at 298–673 K and also for the study of ammonia sorption on the same samples. Pumping at room temperature results in the departure of water of crystallization; the protons, which…

A sulfide ion at the center of an Ni6 prism capped by two additional Ni atoms, and the presence of nine μ2-StBu bridges are the characteristic features of the structure of 1. The mean oxidation state for nickel in diamagnetic 1 is + 1.25. The anion 1 is the first pure nickel–sulfur complex with nickel in an unusual ox…

Grain‐oriented Bi 4 Ti 3 O 12 ceramics have been prepared by hot‐pressing. Platelike grains align during hot‐pressing; the long‐axis direction perpendicular to the crystal c axis is oriented perpendicular to the pressing direction. The effects of hotpressing conditions such as temperature, pressure, time, and type of…

The band gap of the mixed perovskite BaSn1–xSbxO3 has been reported to be 134 kJ mol–1(J-M. Hermann, M. R. Nunes and F. M. A. da Costa, J. Chem. Soc., Faraday Trans. I, 1982, 78, 1983), corresponding to 1.4 eV, which is the optimum value for solar-energy conversion. In order to confirm this value, pressed discs of the…

The coercivity of Nd-Fe-B sintered magnets has been improved by Al additions. To study the microstructural effect of Al addition, two types of investigation were formed: (1) the change in the wetting behavior of the liquid phase, at the sintering temperature, was studied by measurements of the wetting angle; and (2) t…

The hot working is done at a low strain rate (hot pressing) and a high strain rate (hot rolling). Magnetic alignment induced by the hot working is found to be closely related to the microstructure of the cast ingots and the direction of principal stress. The appropriate structure is a columnar structure. The c-axis of…

Amorphous BN that contains hydrogen could be synthesized by pressure pyrolysis of borazine below 700°C at 100 MPa. The fraction of B and N bonded to H in the pyrolysis product could be controlled by changing the pressure pyrolysis condition. The pyrolysis product at 700°C and 100 MPa showed formation of B‐N‐B bonds of…
