Avaliação de permeação de hidrogênio em célula multiteste e susceptibilidade ao trincamento sob tensão em presença de sulfeto de um aço de especificação API 5L X70
… especially serious because of the high levels of CO2 (carbon dioxide), and especially of H2S (hydrogen sulphide), which accelerate the materials corrosion in contact with petroleum. In this environment that the API 5L X70 steel studied in this research operates. In this context, the work present …

Murine Phenotype Analyses and the Role of TRPV1 in Hypoxia
… reaching a lower value for HR, Tb, ACT, V ̇CO2 (carbon dioxide production) and ventilation. We conclude that the animal care environment provides a novel environment to assess murine phenotype and must be considered in genotype/phenotype assessments. Further, TRPV1 provides a significant …

Co-gasification of coal and biomass
… steam or air. The gasification reaction produces CO2 (Carbon-dioxide), H2 (Hydrogen), CO (Carbon-monoxide), CH4 (Methane) and other lower hydrocarbons. The gas produced from a gasifier, known as syngas, can used to produce electricity and liquid fuels. Coal and biomass are used in a gasfier as …

Development of an Analytical Method for Distinguishing Ammonium Bicarbonate from the Products of an Aqueous Ammonia Co2 Scrubber and the Characterization of Ammonium Bicarbonate
The link between anthropogenic emissions of CO2 with increased atmospheric CO2 levels and, in turn, with increased global temperature has been well established and accepted. Using aqueous ammonia to capture CO2 and produce an inexpensive nitrogen fertilizer, ammonium bicarbonate (ABC) has been …

Design and Optimization of Post-Combustion CO2 Capture
… describes the design and optimization of a CO2-capture unit using aqueous amines to remove of carbon dioxide from the flue gas of a coal-fired power plant. In particular we construct a monolithic model of a carbon capture unit and conduct a rigorous optimization to find the lowest solvent …

Morphological and Physiological Studies of the Carbon Concentrating Mechanism in Chlamydomonas reinhardtii
… reinhardtii possesses a single-cell-based CO2-concentrating mechanism (CCM). The CCM is an important element of algal photosynthesis, metabolism, growth and biomass production, which works by increasing the concentration of inorganic carbon (Ci) in the pyrenoid, a dense RuBisCO-packed …

Modelling and Simulation of Carbon Dioxide Transportation in Pipelines: Effects of Impurities
Carbon dioxide capture, transportation, and storage has been identified as the most promising way to reduce anthropogenic carbon dioxide (CO2) released into the atmosphere. Efforts made to achieve this purpose include the Paris (Climate) Accord. This agreement seeks to encourage countries to take …

Development of CaO-based Sorbents for Post-Combustion Carbon Capture in the Calcium Looping Process
Post-combustion carbon capture with solid sorbents is a low-cost and more efficient alternative to traditional amine technologies for CO2 capture. Calcium looping technology is among the most promising technologies for mitigation of CO2 from industrial flue gases. Low price, high theoretical uptake …

The Carbon Budget of the Mekong River Basin: A Spatial and Temporal Study of Chemical Weathering
The chemical weathering of silicate rocks with carbonic acid is thought to play an important role in the consumption of atmospheric carbon dioxide (CO$_{2}$), which regulates global climate over million--year timescales. However, the climatic implications of chemical weathering of carbonate rocks …
