Safe Use of Flammable Refrigerants in Cooling/Heating Cycles

open access: yes, 2023
The F-Gas regulation and the resulting phasedown of fluorinated hydrocarbons (HFOs) as safe refrigerants effects an increase in research and development activities for alternative low-GWP refrigerants. Besides new synthetic refrigerants, there is a focus

The Insulation Performance of Novel Refrigerant Gas as an Alternative to SF₆ for Medium Voltage Switchgear

open access: yesIEEE Access
Gas-insulated systems are widely utilized in the electric power sector to transmit and distribute electrical energy. Sulphur-hexafluoride (SF6) has dominated gas insulation in high-voltage insulation technology since the early 60s. It is a greenhouse gas

Exploring the Potential of Metal–Organic Frameworks for the Separation of Blends of Fluorinated Gases with High Global Warming Potential

open access: yesGlobal Challenges, 2023
The research on porous materials for the selective capture of fluorinated gases (F‐gases) is key to reduce their emissions. Here, the adsorption of difluoromethane (R‐32), pentafluoroethane (R‐125), and 1,1,1,2‐tetrafluoroethane (R‐134a) is studied in ...

Intrapatient tumour heterogeneity and clonal evolution in an autopsy study of metastatic salivary gland cancer

open access: yesMolecular Oncology, EarlyView.
Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

Protocol for quantifying miRNA trafficking across the endosomal membrane

open access: yesFEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

USE OF MODERN INFORMATION TECHNOLOGIES FOR SIMULATION OF ADVANCED POWER TECHOLOGIES

open access: yesОткрытое образование (Москва), 2016
A server of the Moscow Power Engineering Institute is presented which gives an opportunity to conduct “cloud” simulation of advanced power technologies. Several examples of using such approach are introduced.

Structures and Properties of trans‐1,3,3,3‐Tetrafluoro‐ propene (HFO‐1234ze) and 2,3,3,3‐Tetrafluoropropene (HFO‐1234yf) Refrigerants

open access: yesChemistryOpen, 2020
The refrigerant trans‐1,3,3,3‐tetrafluoropropene (HFO‐1234ze) is used as a replacement for former cooling agents that have been phased‐out due to their global warming potential or ozone depleting potential.

Intracerebral Hemorrhage Induces Monocyte TNF Signaling in Patients That Is Suppressed by BAF312

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Intracerebral hemorrhage (ICH) causes high morbidity and mortality, with neurotoxic inflammation driven by infiltrating monocytes. This study is an in‐depth longitudinal examination of the immune response during the first week of ICH in the presence and absence of the immunomodulatory drug BAF312 (Siponimod).
