Totally visible transparent chloro - Sulphide glasses based on Ga 2S3 - GeS2 - CsCl
(2007-01-01)
In this paper, the influence on optical properties of alkali halides such as CsCl in a covalent glassy matrix has been investigated. Chalcogenide glasses belonging to the (GeS2)-(Ga2S3)-CsCl system with high ratio of CsCl ...
Editorial path and the visibility of scientific publications: an exploratory case study on the journal Tche Quimica
(Univ Estadual Campinas - Sistema Bibliotecas, 2022-01-01)
Introduction: Traditionally, the Hard Sciences have journals as their preferred channel for disseminating research results. However, in Brazil these disciplines are predominantly publish in international journals. Thus, ...
IR-visible upconversion and thermal effects in Pr3+/Yb3+-codoped Ga2O3 : La2S3 chalcogenide glasses
(Iop Publishing Ltd, 2000-12-04)
IR-visible upconversion fluorescence spectroscopy and thermal effects in pr(3+)/Yb3+-codoped Ga2O3:La2S3 chalcogenide glasses excited at 1.064 mum is reported. Intense visible upconversion emission in the wavelength region ...
STUDY OF PHENOL PHOTODEGRADATION WITH TiO2/-WO3 COUPLED SEMICONDUCTORS ACTIVATED BY VISIBLE LIGHT
(Sociedad Chilena de Química, 2006)
Evacuation under limited visibility
(World Scientific, 2015-01)
A multiplicity of situations can trigger off an evacuation of a room under panic conditions. For "normal" (with "normal" meaning absence of obstacles, perfect visibility, etc.) environmental conditions, the "faster is ...
Multi-authorship and its impact on the visibility of research from Puerto Rico
(Information Processing & Management (IPM), 2011)
High-performance ultraviolet-visible driven ZnO morphologies photocatalyst obtained by microwave-assisted hydrothermal method
(2018-02-15)
The use of extensive, time-consuming synthesis and the cost of an additional element in synthesis makes difficult the synthesis of photocatalyst active under a broad wavelength range. We propose a synthesis method to obtain ...
Semi-permanent hair dyes degradation at W/WO3 photoanode under controlled current density assisted by visible light
(2017-01-01)
The indiscriminate use of hair dyes has attracted great deal of attention due to its toxicological and mutagenic aspects demonstrated by some of these substances. Thus, the effluent from beauty salons and domestic sewages ...
UV-visible absorption characteristics of TEOS-derived and Cr-doped silica sonogels aged in different pH solutions and heat treated up to 600 degrees C
(Kluwer Academic Publ, 2003-08-01)
Cr-doped xerogels were obtained by sol-gel process from the acid-catalyzed and ultrasound-stimulated hydrolysis of tetraethoxysilane (TEOS) with addition of CrCl3.6H(2)O in water solution during the liquid step of the ...
CAN STILL IMAGES TELL STORIES? Symptom and temporality in photojournalism narrative theory
(Sbpjor, 2015-06-01)
Temporality is one of the central concepts in defining narrative. In this sense, photojournalism has always been a problem for narratological studies, since traditional image theories understand photography as a figure ...
