Laser-induced breakdown spectroscopy: Extending its application to soil pH measurements
(2015-06-23)
Acid-base equilibria are involved in almost all the processes that occur in soil. The bioavailability of nutrients for plants, for instance, depends on the solubilization of mineral nutrients in the soil solution, which ...
After bleaching enamel remineralization using a bioactive glass-ceramic (BioSilicate)
(2016-01-01)
Tooth bleaching agents may weaken the tooth structure, therefore, it is important to minimize any risks of enamel and dentine damage caused by them. In this way, different materials have been used to avoid or minimize the ...

Immersive, interactive, and collaborative distributed applications, due to their real time and multi-platform characteristics, require a monitoring structure of their functionalities during the development period, which ...
Desenvolvimento de procedimentos de preparo de amostras de difícil mineralização para análise direta por laser-induced breakdown spectroscopy (LIBS)
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2019-08-27)
This doctoral thesis proposes sample preparation combined with the use of laser-induced breakdown spectroscopy (LIBS) for analysis of difficult-to-mineralize samples focusing on the analytical development of LIBS as well ...
Determination of femtosecond ablation thresholds by using laser ablation induced photoacoustics (LAIP)
(Springer, 2013-03)
Femtosecond laser material processing as micromachining and nanoparticles fabrication require a careful control of the fluences deposited on the samples. In many cases, best results are obtained by using fluences slightly ...
Caracterização e composição química do material particulado grosso (MP10) no centro da cidade de São Carlos (SP)
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2015-03-27)
Coarse particulate matter with aerodynamic diameter smaller than 10μm (PM10) have long been considered as air pollutants associated with health issues. They penetrate into the upper respiratory tract, causing respiratory ...
Effect of pulse repetition rate and number of pulses in the analysis of polypropylene and high density polyethylene by nanosecond infrared laser induced breakdown spectroscopy
(ELSEVIER SCIENCE BVAMSTERDAM, 2012-02-01)
Pulse repetition rates and the number of laser pulses are among the most important parameters that do affect the analysis of solid materials by laser induced breakdown spectroscopy, and the knowledge of their effects is ...
Precious, strategic and toxic elements in electronic waste: bibliometric evaluation, proposition of reference material and direct analysis by laser-based techniques and fluorescence spectrometry
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2021-03-26)
Waste electrical and electronic equipment (WEEE) is among the fastest growing types of solid waste in the world. In addition, this is a complex waste stream when it comes to recycling, due to the large variety of valuable ...
Graphical high level analysis of communication in distributed virtual reality applications
(2015-01-01)
Analysing distributed virtual reality applications communicating through message-passing is challenging. Their development is complex, and knowing if something is wrong depends on the states of each process, defects (bugs) ...
Estudios comparativos de emisión de gases en el procesado laser sobre cloruro de polivinilo
(2008-11-03)
Resumen: El PVC se degrada químicamente cuando se calienta por acción láser. Las fumarolas emitidas presentan altos niveles de hidruro de cloro, el cual al combinarse con el agua forma el ácido clorhídrico, compuesto ...
