| The material was made by adding lanthanum to an existing catalyst, which led to a ninefold increase in catalytic activity. |
|
| Its chemical properties are similar to those of lanthanum, the element above it in the periodic table. |
|
| It is extracted from its ores by heating lanthanum metal with ytterbium oxide. |
|
| Elements in this group are also known as the lanthanides after the first element in that group, lanthanum. |
|
| We see cerium, lanthanum, neodymium, and so forth, which indicate we are dealing with a rare-earth mineral, and that can mean big problems. |
|
| Samarium is a rare earth element, one of the elements that occupy the space in Row 6 of the periodic table between lanthanum and hafnium. |
|
| In contrast, the prolonged increase in cytosolic calcium was greatly enhanced in the presence of gadolinium or lanthanum chloride. |
|
| The relative difficulty in identifying certain elements has given birth to such names as lanthanum, krypton and dysprosium. |
|
| It belongs to the family known as the lanthanides, named after the first member of that series, lanthanum. |
|
| There is no evidence from animal studies that lanthanum crosses the blood brain barrier. |
|
| Abdominal X-rays of patients taking lanthanum carbonate may have a radio-opaque appearance typical of an imaging agent. |
|
| However, both germination and elongation are significantly inhibited by the inclusion of calcium channels blockers, including lanthanum, gadolinium, or verapamil. |
|
| When added to steel, lanthanum not only improves malleability, it also increases the steel's impact resistance. |
|
| The Sichuan ore has more lanthanum, less praseodymium and neodymium, and about the same amount of cerium as the Bayan Obo deposit. |
|
| Lanthanides are part of a group of 15 chemical elements ranging from lanthanum to lutetium in the periodic table of chemical elements. |
|
| Use of lanthanum or scandium ion to amplify nucleic acid polymerase activity and optionally also to inhibit nuclease activity. |
|
| Element 121 should be similar in its chemical properties to lanthanum and actinium, but detailed properties have not been predicted. |
|
| An excess of lanthanum nitrate is added, then the released nitric acid is titrated with sodium hydroxide solution. |
|
| Caution should be exercised in these patients, as elimination of absorbed lanthanum may be reduced. |
|
| There was a dose-related increase in lanthanum concentration in the femur at the end of the 52-week treatment period. |
|
|
|
| The lanthanum level in amniotic fluid was more than 10-fold lower than those found in plasma in the dosed animals. |
|
| In order to bind dietary phosphate efficiently, lanthanum should be administered with or immediately after a meal. |
|
| In the motion picture industry, lanthanum is used in studio lighting and projection. |
|
| Not to mention rare elements such as lanthanum, cerium, and neodymium, essential to modern technology and commanding high prices. |
|
| Rado has pioneered the use of number of materials unique to watch making, like hardmetal, ceramics, lanthanum and sapphire crystal. |
|
| Use as a luminophor in plasma systems of a compound based on an yttrium, lanthanum, gadolinium or lutecium phosphate doped with at least one rare earth chosen from the group comprising terbium, praseodymium and cerium. |
|
| The Bayan Obo deposit is slightly richer in praseodymium and neodymium than the Mountain Pass bastnasite is, primarily at the expense of the lanthanum content, which is 10 percent greater in the Mountain Pass ore. |
|
| Pre-clinical studies also found that chronically renal impaired rats given high doses of lanthanum carbonate resulted in osteomalacia, and non-dietary phosphate supplements minimized this effect. |
|
| The metal is conveniently prepared by metallothermic reduction of its oxide, Sm2O3, with lanthanum metal, followed by distillation of the samarium metal, which is one of the most volatile rare-earth elements. |
|
| As well as being sold in different lengths and thicknesses, TE can be made either from pure tungsten or alloyed with a small percentage of a metal such as thorium, lanthanum, cerium, zirconium, or a combination of those. |
|
| A series of in vitro bone culture studies clearly demonstrated that lanthanum caused a dose-dependent inhibition of osteoblast and osteoclast differentiation. |
|
| Lanthanum is a rare-earth trace metal that naturally occurs in monazite sand and coal. |
|
| Significant values were 3850 ppm Cerium, 1890 ppm Lanthanum, 964 Neodymium and 259 Yttrium. |
