PASSIVATION OF THE INP(100) SURFACE USING (NH4)(2)S-X
, 1995 InP(100) surface treated with (NH4)(2)S-x has been investigated by using photoluminescence(PL), Auger electron spectroscopy and X-ray photoelectron spectroscopy. It is found that PL intensity increased by a factor of 3.3 after (NH4)(2)S-x passivation and

Active NH4+ absorption by the thick ascending limb
, 1988 Isolated perfused medullary thick ascending limbs from rabbits were studied to determine the mechanism of ammonium ion absorption. Under control conditions, thick ascending limbs spontaneously absorbed NH4+ and generated a lumen-positive potential. When

Increasing NH4+ retention efficiency of sandy soils by adding a modified kaolin material: Mesolite
, 2004 Water and ammonium retention by sandy soils may be low and result in leaching of applied fertiliser. To increase water and nutrient retention, zeolite is sometimes applied as a soil ameliorant for high value land uses including turf and horticulture.\ud \
