Manganese gluconate, A greener and more degradation resistant agent for H2S oxidation using liquid redox sulfur recovery process

Heliyon, 2020
Iron chelate liquid redox sulfur recovery (LRSR) has been one of the most frequently recommended technologies for the oxidation of H2S in natural gas into elemental sulfur, particularly when the acid gas has a high CO2/H2S molar ratio.

Photoinduced chlorophyll charge transfer state identified in the light-harvesting complex II from a marine green alga Bryopsis corticulans

iScience, 2023
Summary: The light-harvesting complex II of Bryopsis corticulans (B-LHCII), a green alga, differs from that of spinach (S-LHCII) in chlorophyll (Chl) and carotenoid (Car) compositions. We investigated ultrafast excitation dynamics of B-LHCII with visible-

Sizing of reactors by charts of Damköhler's number for solutions of dimensionless design equations

Heliyon, 2020
The reaction kinetic rate and mass transport play an important role in the sizing and scale-up of reactors. The Damköhler's dimensionless number (Da) is the quotient of these effects.

Hydrophobic-modified metal-hydroxide nanoflocculants enable one-step removal of multi-contaminants for drinking water production

iScience, 2021
Summary: Flocculation is a mainstream technology for the provision of safe drinking water but is limited due to the ineffectiveness of conventional flocculants in removing trace low-molecular-weight emerging contaminants.

Influence of chemical residue on the environmental engineering [PDF]

INTERNATIONAL JOURNAL OF EXPERIMENTAL RESEARCH AND REVIEW, 2020
This review summarizes waste management and there is a need for better understanding the scientific findings for recycling the waste materials and suggests areas where further research is needed. In major cities around the world, waste management today is based on a comprehensive, sustainable and environmentally sound system of maximization.

Production of biodiesel by enzymatic transesterification of waste sardine oil and evaluation of its engine performance

Heliyon, 2017
Waste sardine oil, a byproduct of fish industry, was employed as a low cost feedstock for biodiesel production. It has relatively high free fatty acid (FFA) content (32 mg KOH/g of oil).
