Self-Q-switched operation of the all-fiber laser using erbium and samarium fibers in the cavity is realized experimentally. This passively Q-switched all-fiber laser produces very stable pulses with energy of 142 nJ and duration of 450 ns. The experimental results were well reproduced by the results
A simple procedure was developed to compare chelating agents for (153)Sm complexes as a preliminary step to synthesise bifunctional analogues. Several variables affecting the efficiency of complex stability were investigated, such as the pre-organisation concept, cavity size, and the nature of
The gamma-deprotonation of a samarium(III) bis(trimethylsilyl)amide complex derived from a dimetallated trans-dioxaporphyrinogen has been achieved through stabilisation of the counter cation within the macrocyclic cavity.
Brachytherapy continues to play an important role in the management of cancers of several sites, including the head and neck, brain, uterine cervix, endometrium, and prostate. The physical advantages of brachytherapy result from a superior localization of dose to the tumor volume. In brachytherapy,
The isostructural rare-earth titanium antimonides RE 2Ti 11 - x Sb 14 + x ( RE = Sm, Gd, Tb, Yb) have been synthesized by arc-melting reactions of the elements. Single-crystal X-ray diffraction revealed that they adopt a new structure type (Pearson symbol oP54, space group Pnma, Z = 2; a =
The reaction of lanthanide nitrates with cucurbit[n]urils (CBn, n = 5, 6, 7) under hydrothermal conditions in the presence of perrhenic acid and, for some of them, other reactants such as KNO(3) yielded 14 new complexes which were crystallographically characterized and present some original
In 51 patients, the conventional therapy was combined with application of plate prostheses with samarium-cobalt magnets. Clinical investigations showed a beneficial effect of the constant magnetic field on the inflammation relief, erosion epithelialization and papules disappearing from the oral
Introducing of topological insulator concept for fluctuating valence compound - samarium hexaboride - has recently initiated a new round of studies aimed to clarify the nature of the ground state in this extraordinary system with strong electron correlations. Here we discuss the data of magnetic
Osteoarthritis is the most common type of arthropathy and after cardiovascular diseases is the most disabling disease in developing countries. The dosimetry for the clinical application of 153-samarium-hydroxymacroaggregates (¹⁵³Sm-HM) for radiation synovectomy (RSV) and palliative treatment for
This paper examines how physical factors such as the depth of the excision cavity below the skin surface and its distance from the underlying lung may impact upon the choice between the use of an electron field (from a Varian Clinac 1800) or an implant (using a double plane of iridium-192 wires).
Here, we report our trials to regulate the luminescence performance of the macrocyclic samarium(III) complex and prepare four excellent luminescent Sm(III) complex-doped poly(methylmethacrylate) (PMMA) composites. Four 23-membered [1 + 1] Schiff-base macrocyclic mononuclear Sm(III) complexes,
BACKGROUND
Rare earth magnets have been used in prosthodontics, but their tendency for corrosion in the oral cavity and insufficient attractive forces limit long-term clinical application.
OBJECTIVE
The purpose of this study was to evaluate the attractive force of different types of new-generation
In the penta-nuclear title complex,
