The inner transition elements occupy a position in between the elements lanthanum (Z=57) and hafnium (Z=72), and between actinium (Z=89) and rutherfordium (Z=104). Elements 58-71, which follow lanthanum, are the lanthanides, and elements 90-103, which follow actinium, are the actinides.There is actually some question as to whether lanthanum and actinium should be considered as part of the ...

Dimoulas et al. demonstrated that high quality lanthanum hafnium oxide (LHO) dielectric layers deposited by molecular beam epitaxy show promising thermodynamic and electrical properties . Atomic layer deposition (ALD) is an excellent deposition method for high- k film growth due to its superb process controllability, even for extremely low ...
Chromium alloys were coated with yttrium, lanthanum, and hafnium, either singly or in com- bination, by pack cementation. Based on ductile-brittle transition temperature, a complex Cr + Y + La coating offered the most potential for protecting chromium alloys from nitrogen embrittlement.
Crystalline hybrid organic/inorganic ion exchangers based on zirconium phosphate and phosphonate compounds were evaluated for application in radium-223 generator for radiopharmaceutical applications. Various compositions were synthesized and the selectivity of these materials was determined for inactive lanthanum, hafnium and barium, and radiotracers yttrium-88 and barium-133.

The solution was traced with the radioisotopes Y-88 or Ba-133 (or with 4 ppm inactive barium, lanthanum or hafnium). The solid was separated from solution by filtration through 0.2 μm syringe filters, and aliquots counted for gamma-activity (Wallac Model 1410) or analyzed for Ba, La and Hf content using atomic adsorption spectroscopy (AAS).

lanthanum (La), chemical element, a rare-earth metal of Group 3 of the periodic table, that is the prototype of the lanthanide series of elements. Lanthanum is a ductile and malleable silvery white metal that is soft enough to be cut with a knife. It is the second most reactive of the rare-earth
Answer (1 of 3): We don't. you are just badly reading the periodic table. admittedly it not clear if you are not used to using one. after lanthanum you are supposed to read the first line of the f block (known as the lanthanides) which is usually placed under the reste of the periodic table. afte...

Hafnium isopropoxide isopropanol adduct was used as a precursor to prepare mesoporous HfO 2 by the thermohydrolytic approach. The high active surface area and uniform porosity enables these HfO 2 to be used as adsorbents for sequestration of heavy metal ions.
The semiconductor industry continues to scale (shrink) transistor dimensions to both increase the number of transistors per integrated circuit and their speed. One important aspect of scaling is the need to decrease the equivalent oxide thickness of the transistor gate dielectric while minimizing leakage current. Traditional thin layer SiO2 or SiOxNy films have been replaced by higher ...
