Effective thermal properties and proximate analysis of coke-coal fines mixtures
(2021-06-04)
We report the effective thermal properties at room temperature and proximate analysis
of three mixtures of coke and carbon fines formed by uniaxial pressing at 30 MPa. Using
differential scanning calorimetry and ...
Modelling of DHA Production from S. Limacinum ouc88: fed-batch perspectives
(2021-09-12)
Biotechnology and its need to improve industrial processes have shown the need for
techniques that allow processes optimization. Computer simulation offers the advantage of
determining production prospects without ...
Influence of compression rings on the dynamic characteristics and sealing capacity of the combustion chamber in diesel engines
(Lubricants, 2021-03-02)
Internal combustion engines are widely implemented in several applications; however,
they still face significant challenges due to the sealing capacity of the compression rings. Gas leakage
through the crankcase, also ...
Electrochemical synthesis of titanium dioxide nanostructures and its application in the in dye photocatalytic removal
(2021-06-04)
By electrochemical anodization to titanium sheets, titanium dioxide nanostructures
were sintered for 10 V and 20 V and times of 3 hours and 5 hours. For the electrolytic solution,
0.3 g of ammonium fluoride, 97 mL of ...
Wear synergy of copper-iron mixtures processed by powder metallurgy
(Rasayan Journal of Chemistry, 2021)
Through the powder metallurgy process, copper and iron powders were mixed in the proportions Cu between 15% to
75% and iron from 25% to 85% that made up the binary material systems. The X-ray diffraction technique was ...
Characteristics of refractory bricks used in the coke production kilns in Colombia
(2021-06-04)
A study has been carried out on the main physicochemical characteristics of the
refractory bricks that are currently used in traditional coke-making kilns in Colombia. Two
classes of material (brick) used in this industry ...
Anticorrosive evaluation of copper-iron mixtures processed by powder metallurgy
(Rasayan Journal of Chemistry, 2021)
Through the powder metallurgy process, copper and iron powders were mixed in the proportions Cu between 15% to
75% and iron from 25% to 85% that made up the binary material systems. Material systems were topographically ...
Computer-Aided Evaluation of Ethanol Production from a Continuous Operating Mode using Simulink
(2021-09-10)
Fossil fuels have become a great energy source worldwide. However, its prolonged
use has caused severe environmental pollution problems. Biofuels generated from biomass as a
product of microbial biotechnology emerge as ...
Determination of the structural efficiency of short bridges according to their physical and economic characteristics
(2021-06-04)
Bridges are structures designed and built to overcome natural and artificial
obstacles. The analysis and design of bridges is carried out following principles of physics
applied to engineering. The aim is to estimate the ...
Dynamic Simulation of Bioethanol Production from Banana Rejected using Flocculating Yeast
(2021-09-12)
A dynamic model is presented to simulate a fermentation process for bioethanol
production from banana rejected using a batch system. The critical model feature is using an
inhibition function to relate substrate concentration ...
