HFO1234ze(e) As an Alternative Refrigerant for Ejector Cooling Technology

open access: yesEnergies, 2019
The paper presented a mathematical assessment of selected refrigerants for the ejector cooling purpose. R1234ze(e) and R1234yf are the well-known refrigerants of hydrofluoroolefins (HFOs), the fourth-generation halocarbon refrigerants.

Exposure of adult sea urchin Strongylocentrotus intermedius to stranded heavy fuel oil causes developmental toxicity on larval offspring [PDF]

open access: yesPeerJ, 2022
Heavy fuel oil (HFO) spills pose serious threat to coastlines and sensitive resources. Stranded HFO that occurs along the coastline could cause long-term and massive damage to the marine environment and indirectly affect the survival of parental marine ...

Fate and Impacts of Triclosan, Sulfamethoxazole, and 17β-estradiol during Nutrient Recovery via ion Exchange and Struvite Precipitation [PDF]

open access: yes, 2017
Increasing emphasis on resource recovery from wastewater highlights the importance of capturing valuable products, e.g., nutrients such as nitrogen and phosphorus, while removing contaminants, e.g., organic micropollutants. The objective of this research

Investigation on insulation properties of HFO‐1336mzz(E) and N2/CO2 mixtures as SF6 substitutes in gas‐insulated electrical applications

open access: yesHigh Voltage, 2023
The emissions of SF6 have been restricted owing to 3400 years of atmospheric lifetime and high global warming potential (GWP) as an insulating gas in gas‐insulated electrical equipment.

“Low-” versus “high”-frequency oscillation and right ventricular function in ARDS. A randomized crossover study

open access: yesJournal of Intensive Care, 2018
Background Recent, large trials of high-frequency oscillation (HFO) versus conventional ventilation (CV) in acute respiratory distress syndrome (ARDS) reported negative results. This could be explained by an HFO-induced right ventricular (RV) dysfunction/

Direct tunneling through high-$\kappa$ amorphous HfO$_2$: effects of chemical modification [PDF]

open access: yes, 2014
We report first principles modeling of quantum tunneling through amorphous HfO$_2$ dielectric layer of metal-oxide-semiconductor (MOS) nanostructures in the form of n-Si/HfO$_2$/Al. In particular we predict that chemically modifying the amorphous HfO$_2$

Analysis of heavy fuel oil use by ships operating in Canadian Arctic waters from 2010 to 2018

open access: yesFACETS, 2020
In 2018, The International Maritime Organization, officially proposed consideration of a ban on heavy fuel oil (HFO) use by ships in the Arctic, because of the widely accepted understanding that HFO presents a threat to the marine environment.
