A Lifecycle Assessment of a Low-Energy Mass-Timber Building and Mainstream Concrete Alternative in Central Chile
(MDPI, 2022)
While high-rise mass-timber construction is booming worldwide as a more sustainable
alternative to mainstream cement and steel, in South America, there are still many gaps to overcome
regarding sourcing, design, and ...
Effect of plasma oxidation treatment on production of a SiOx/SiOxCyHz Bilayer to protect carbon steel against corrosion
(2021-01-01)
Because of its excellent properties, carbon steel is a material widely used in several sectors. However, it is easily corroded when exposed to the environment. Seeking to remedy this problem, the possibility of coating ...
Dominance of in situ produced particulate organic carbon in a subtropical reservoir inferred from carbon stable isotopes
(2020-12-01)
Sources of particulate organic carbon (POC) play important roles in aqueous carbon cycling because internal production can provide labile material that can easily be turned into CO2. On the other hand, more recalcitrant ...
Hydrogen production from ethanol with low carbon monoxide generation in one-pot reaction with iron oxides as catalysts
(Elsevier, 2014-07-12)
Bulk γ-Fe2O3 (maghemite) and Fe3O4 (magnetite) were synthesized with Fe(III) hydroxyacetate as an intermediate during the preparation step. The fresh and used catalysts were characterized by X-ray diffraction, N2 adsorption ...
Bottom-Up analysis of energy consumption and carbon emissions, with particular emphasis on human capital investment
(Scientific Research, 2013-12)
Short-term and mid-term projections of energy consumption and carbon emissions raise significant concern about the availability of the necessary energy resources to meet the growing demand and about the impact of emissions ...
Processing and characterization of ablative composites used in rocket motors
(Sage Publications Ltd, 2014-08-01)
The main objective of this research work was to obtain two formulations of ablative composites. These composites are also known as ablative structural composites, for applications in atmospherically severe conditions ...
Use of sugarcane bagasse and grass hydrolysates as carbon sources for xylanase production by Bacillus circulans D1 in submerged fermentation
(Elsevier B.V., 2005-12-01)
The use of sugarcane bagasse and grass as low cost raw material for xylanase production by Bacillus circulans D1 in submerged fermentation was investigated. The microorganism was cultivated in a mineral medium containing ...
Biosurfactants production by yeasts using soybean oil and glycerol as low cost substrate
(Sociedade Brasileira de Microbiologia, 2012-03-01)
Biosurfactants are bioactive agents that can be produced by many different microorganisms. Among those, special attention is given to yeasts, since they can produce many types of biosurfactants in large scale, using several ...
