Reflections and guidelines for the study of vernacular landscapes
(Univ Fed Goias, Inst Estudos Socio-ambientais, 2021-12-01)
Coined by J.B Jackson in the 1970s, the concept of Vernacular Landscape was used to appreciate certain landscapes in the United States that were considered banal or common, seeking to interpret and value it. Since then, ...
On the Limit of Frequency of Electrochemical Oscillators and Its Relationship to Kinetic Parameters
(AMER CHEMICAL SOCWASHINGTON, 2012-05)
The class of electrochemical oscillators characterized by a partially hidden negative differential resistance in an N-shaped current potential curve encompasses a myriad of experimental examples. We present a comprehensive ...
Theoretical surface-enhanced Raman spectra study of substituted benzenes II. Density functional theoretical SERS modelling of o-, m-, and p-methoxybenzonitrile
(PERGAMON-ELSEVIER SCIENCE LTD, 2008-12-01)
The SERS modelling of o-, m-, and p-methoxybenzonitrile has been performed following the same methodology that in Part I. Optimized structure obtained from DFT calculations in a B3LYP-LANL2DZ level of calculation shows ...
Theoretical design proposal for simulated hot asphalt mixture at a temperature below zero degrees Celsius
(Institute of Physics Publishing, 2020-02-28)
In the world there are adverse climates, climates that hinder the good construction and paving of roads, generating insecurity among the locals and visitors. This over time affects the economy of a country, as a road boosts ...

Substituents role in zinc phthalocyanine derivatives used as dye-sensitized solar cells. A theoretical study using Density Functional Theory
(2015)
A series of zinc phthalocyanine dyes with different electron-donating and electron-withdrawing substituents and using the COOH as the anchor group that interacts with the semiconductor (TiO2) surface, were studied employing ...
