(1975)It is shown that the energy-momentum tensor of the electromagnetic field, for an electron in a curved space, may be split into two dynamically independent parts. One of them, the radiation tensor, has the following remarkable ...
-
(Elsevier, 2015)We examine the timing and magnitude of the last glacial maximum (LGM) and the last glacial termination (LGT) in northwestern Patagonia, situated in the middle latitudes of South America. Our data indicate that the main ...
-
(SOCIEDAD BIOLGIA CHILE, 2005)In this paper we develop a method to estimate lung Volume using chest x-rays of small mammals. We applied this method to assess the lung volume of several rodents. We showed that a good estimator of the lung volume is: ...
-
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2016)Patterns in rainfall and soil water availability are considered to be the main drivers governing arid and semiarid ecosystems. While the mechanisms by which water limits aboveground net primary production has been widely ...
-
(John Wiley & Sons, 2013)The Raman and surface enhanced Raman scattering (SERS) spectra of a black dyed silk sample (BDS) were registered. The spectral analysis was performed on the basis of Raman and SERS spectral data of isolated samples of ...
-
(Pergamon-Elsevier, 2016)Accurate characterization of two phase bubbly flows is crucial in many industrial processes such as fluidized reactors, ore froth flotation, etc. The bubble size determines the rate at which components present in the gas ...
-
(Sociedad Chilena de Quimica, 2015)The sensor 1-(4-mercaptophenyl)-2,4,6-triphenylpyridinium perchlorate compound was vibrationally characterized using Raman and the Surface-Enhanced Raman techniques, SERS and Shell-Isolated Nanoparticles-Enhanced Raman ...

(Soc Chilena Quimica, 2015)The sensor 1-(4-mercaptophenyl)-2,4,6-triphenylpyridinium perchlorate compound was vibrationally characterized using Raman and the Surface-Enhanced Raman techniques, SERS and Shell-Isolated Nanoparticles-Enhanced Raman ...
-
(Johm Wiley, 2012)Important improvements of diseases of the rotator cuff supraspinatus tendons are seen after shock wave (SW) treatment. Neo-angiogenesis stimulation and hypercellularization result from short periods of treatment. The present ...
-
(Natl Inst R&D Materials Physics, 2020)CuIrSnS4, CuIrSnSe4 and CuIrSnS2Se2 were synthetized by a solid-state reaction at 700 degrees C. Powder X-ray diffraction patterns were consistent with normal spinel-type structure. Scanning electron microscopy (SEM-EDS) ...
-
(2014)A material characterization of two artworks discovered in the San Francisco Church, Santiago, Chile, was performed using micro-Raman spectroscopy. Structural painted beams and a wall painting that belong to the same time ...
-
(Sociedad Chilena Química, 2016)The main pigments in the painting by the Chilean artist Ignacio Gumucio were identified by using micro-Raman spectroscopy. Three works by the artist, two paintings with wooden stand and a wall painting were analyzed. ...
-
(Mimesis Edizioni, 2017)Micro-Raman spectroscopy was used to analyze and identify pigments and determine the palette of color in wall paintings from four churches of the Colonial Period, in the Bolivian highlands. The ancient churches Santiago ...
-
(Taylor & Francis, 2017)Raman, surface-enhanced Raman scattering, and shell isolated nanoparticles-enhanced Raman scattering techniques were used to study the indigo-nanoparticle interaction nature. Silver nanoparticles were employed with and ...
-
(1989)Raman and infrared spectra of evaporated uranyl superphthalocyanine (UO2SPc) films are reported. Raman spectra of UO2SPc (formed by five isoindoline subunits) depart from the general spectral trends observed in metallated ...
-
(Sociedad Chilena de Quimica, 2013)Yellow blocks from the archaeological site Playa Miller 7 (PLM7), on the coast of Atacama Desert in northern Chile, were analyzed by Raman spectroscopy and X-ray fluorescence (XRF) portable. Our results identify for the ...
-
(2011)Pigments and fresco-related materials from the wall painting Historia de Concepción by Gregorio De La Fuente in Concepción, Chile were identified by Raman microscopy. The pigments were compared with those obtained from the ...
-
(Elsevier, 2012)The Raman spectra (1800–200 cm−1) of isolated dried collagen types I and III were recorded at different times after shockwave (SW) application in aqueous media. SWs were applied in a single session. One week after the ...
-
(SOC CHILENA QUIMICA, 2010-08-18)Seven pigments of patrimonial interest for the Chilean artwork were analyzed by means of Raman spectroscopy by using the 632.8 nm excitation laser line. Samples were supplied by the National Center of Conservation and ...
-
(2011)Infrared, Raman and surface-enhanced Raman scattering (SERS) spectra of 3-(1-phenylpropan-2-ylamino)propanenitrile (fenproporex) have been recorded. Density functional theory (DFT) with the B3LYP functional was used for ...
