Investigation of Ester- and Amide-Linker-Based Porous Organic Polymers for Carbon Dioxide Capture and Separation at Wide Temperatures and Pressures
(
American Chemical Society
, 2016 , Article)
Organic compounds, such as covalent organic framework, metal–organic frameworks, and covalent organic polymers have been under investigation to replace the well-known amine-based solvent sorption technology of CO2 and ...
Bioremediation of Crude Oil Contaminated Desert Soil: Effect of Biostimulation, Bioaugmentation and Bioavailability in Biopile Treatment Systems
(
MDPI AG
, 2016 , Article)
This work was aimed at evaluating the relative merits of bioaugmentation, biostimulation and surfactant-enhanced bioavailability of a desert soil contaminated by crude oil through biopile treatment. The results show that ...
Adsorption Equilibrium and Kinetics of Nitrogen, Methane and Carbon Dioxide Gases onto ZIF-8, Cu10%/ZIF-8, and Cu30%/ZIF-8
(
American Chemical Society
, 2019 , Article)
Various ZIFs (ZIF-8, Cu10%/ZIF-8, and Cu30%/ZIF-8) were exploited in the adsorption of N2, CH4, and CO2 gases over a temperature range from 25 to 55 C. The dual site Langmuir model was used to describe the measured adsorption ...
On the nanogate-opening pressures of copper-doped zeolitic imidazolate framework ZIF-8 for the adsorption of propane, propylene, isobutane, and n-butane
(
Springer New York LLC
, 2019 , Article)
In this study, a zeolitic imidazolate framework-8 (ZIF-8) and its copper-doped variants (Cu-doped ZIF-8) were synthesized using a rapid microwave technique. The products were characterized by XRD, NanoSEM, FTIR, Raman ...
Advancements in concrete mix designs: High-performance and ultrahigh-performance concretes from 1970 to 2016
(
American Society of Civil Engineers (ASCE)
, 2018 , Article)
This paper reviews the methods adopted to produce high-performance concrete (HPC) and ultrahigh-performance concrete (UHPC). The chronological development of these concretes in terms of their constituents, mixture proportions, ...
Solar Energy Storage via Thermochemical Metal Oxide/Metal Sulfate Water Splitting Cycle
(
Materials Research Society
, 2018 , Conference Paper)
This paper reports the effect of Ar molar flow-rate on thermodynamic efficiency analysis of zinc oxide-zinc sulfate (ZnS-ZnO) water splitting cycle useful for solar H2 production. The thermodynamic efficiency analysis is ...
Synthesis and Performance Evaluation of Pulse Electrodeposited Ni-AlN Nanocomposite Coatings
(
Hindawi Limited
, 2018 , Article)
This research work presents the microscopic analysis of pulse electrodeposited Ni-AlN nanocomposite coatings using SEM and AFM techniques and their performance evaluation (mechanical and electrochemical) by employing ...
New insights on estimating pore size distribution of latex particles: Statistical mechanics approach and modeling
(
Elsevier B.V.
, 2016 , Article)
New statistical mechanics approach for pore size distribution applied in wide the relative pressure range is proposed. The new proposed model was applied to nitrogen adsorption-desorption isotherms at 77 K onto five ...
Erosion behavior of API X120 steel: Effect of particle speed and impact angle
(
MDPI AG
, 2018 , Article)
The dry erosion behavior of API-X120 pipeline steel was investigated, under the erosive interaction of aluminum oxide particulates, in a range of speed (43-167 m·s-1) and impact angle (30°-90°). Erosion behavior is ...
Monitoring and measurement of microalgae using the first derivative of absorbance and comparison with chlorophyll extraction method
(
Springer International Publishing
, 2018 , Article)
Monitoring of microalgae in water supplies and industrial applications are becoming increasingly important, yet there are few options available that are simple and accurate, and can provide real-time information. The present ...
