Tetragonal-cubic phase boundary in nanocrystalline ZrO(2)-Y(2)O(3) solid solutions synthesized by gel-combustion
(ELSEVIER SCIENCE SA, 2011)
By means of synchrotron X-ray powder diffraction (SXPD) and Raman spectroscopy, we have detected, in a series of nanocrystalline and compositionally homogeneous ZrO(2)-Y(2)O(3) solid solutions, the presence at room temperature ...
SN-38-loaded nanofiber matrices for local control of pediatric solid tumors after subtotal resection surgery
(Elsevier, 2016-02)
In addition to surgery, local tumor control in pediatric oncology requires new treatments as an alternative to radiotherapy. SN-38 is an anticancer drug with proved activity against several pediatric solid tumors including ...
Evidence for a regulated Ca2+ entry in proximal tubular cells and its implication in calcium stone formation
(The Company of Biologists, 2019)
Abstract: Calcium phosphate (CaP) crystals, which begin to form in the early segments of the loop of Henle (LOH), are known to act as precursors for calcium stone formation. The proximal tubule (PT), which is just
upstream ...
Spectroscopic studies of the Eu3+ and Er3+ ions in the fluorozirconate LaZr2F11 matrix
(Elsevier B.V., 2000-02-15)
An investigation by optical spectroscopy of the Eu3 + and Er3 + active ions in the crystallized fluorozirconate matrix LaZr2F11 is presented. The D-5(1) --> F-7(0-5) emission lines of Eu3 + are used to extract the F-7(0-5) ...
Structural and photoluminescence properties of Eu3+ doped α-Ag2WO4 synthesized by the green coprecipitation methodology
(2015-01-01)
Europium doped silver tungstates α-Ag2-3xEuxWO4 (x = 0, 0.0025, 0.005, 0.0075 and 0.01 mol) were synthesized by the coprecipitation method at 90 °C for 30 minutes. These crystals were structurally characterized by means ...
Silver Molybdate and Silver Tungstate Nanocomposites with Enhanced Photoluminescence
(Intech Europe, 2014-08-01)
Silver molybdate (Ag2MoO4) and silver tungstate (Ag2WO4) nanomaterials were prepared using two complementary methods, microwave assisted hydrothermal synthesis (MAH) (pH 7, 140 degrees C) and co-precipitation (pH 4, 70 ...
Luminescent gold and silver complexes with the monophosphane 1‑(PPh2)‑2-Me‑C2B10H10 and their conversion to gold micro- and superstructured materials
(ACS publications, 2014)
Gold and silver complexes containing the monophosphane
1-PPh2-2-Me-l,2-C2B10H10 with different coordination numbers (2, 3)
have been synthesized: [M(7,8-(PPh2)2-C2B9H10)(1-PPh2-2-Me-

The discovery of stromatolites developing at 3570 m above sea level in a high-altitude volcanic lake Socompa, Argentinean Andes
(Public Library Of Science, 2013-01-07)
We describe stromatolites forming at an altitude of 3570 m at the shore of a volcanic lake Socompa, Argentinean Andes. The water at the site of stromatolites formation is alkaline, hypersaline, rich in inorganic nutrients, ...
