This work developed flame retarded glass fiber reinforced polyamide 6 (FR-GFPA) composites with excellent mechanical properties, thermal stability and flame retardancy using a novel flame retardant, l...
We propose and demonstrate a stable single-longitudinal-mode lanthanum-codoped bismuth oxide-based erbium doped fiber ring laser. The combination of a free-space thin-film filter and a Lyot filter ena...
The less than 0.45 mm filterable lanthanum (La), cerium (Ce), praseodymium (Pr) and yttrium (Y) concentrations in rainfall, cloud water, stream and groundwater in the upper River Severn catchments of ...
In recent years, lanthanum(La)compounds have been increasingly used in the optical and electronic industries. Such industrial sources of La pose potential environmental problems, and it is therefore n...
Mesoporous lanthanum phosphate was synthesized by supramolecular self-assembly of cetyltrimethylammonium bromide and lanthanum nitrate following digestion in phosphoric acid. TGA-DTA, XRD and SEM were...
Purpose: The objective of the work was to investigate changes in structure and properties of Ag+(0,5%wt)La alloy and its difference to the comparative Ag+(7,5%wt)Cu and pure Ag materials. Design/meth...
2002Vol.37No.4pp.499-502DOI: Influence of the Pseudogap on the Inelastic Neutron Scattering Spectra of the Underdoped Lanthanum Cuprate LOU Ping,1,2 CAO Lie-Zhao,1 and WU Hang-She...
2003Vol.39No.3pp.323-326DOI: Analytical Potential Energy Function for the Ground State X1Σ+ of Lanthanum Monofluoride CHEN Lin-Hong and SHANG Ren-Cheng Center for Astro...
A feeding trial was conducted on pigs to study the effect of La on their growth performance. Sixty barrows were randomly assigned to two groups (each of which included three replicates) and they were ...
The effect of La and Ba additives on the thermal stabilization of g-Al2O3 was investigated through total-surface-area measurements. The parameters considered were additive content, calcination tempera...
Abstract: The retention of hazardous species, including many of the lanthanides, on soils and sediments is vital for maintaining environmental quality. In this study, high-resolution transmission elec...
