Experimental Performance of R-1234yf as a Drop-in Replacement for R-134a in Domestic Refrigerators
, 2012 Concerns about anthropogenic climate change have generated an interest in low global warming potential (GWP) refrigerants and have spawned policies and regulations that encourage the transition to low GWP refrigerants. Recent research has largely focused

A Review of Sensing Technologies for New, Low Global Warming Potential (GWP), Flammable Refrigerants
, 2023 Commercial refrigeration systems currently utilize refrigerants with global warming potential (GWP) values ranging from 1250 to 4000. The advent of low GWP alternatives (GWP 150) is expected to significantly curtail direct emissions from this segment and

Carbon emission assessment of tunnel infrastructures: From construction to operation
Deep Underground Science and Engineering, EarlyView.This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Variations in Line Profiles of Atomic Transitions in RR Lyrae Stars
The Astronomical JournalWe have investigated the absorption shapes of atomic lines and H α in RR Lyrae stars. We used the database of high-resolution spectra gathered with the Las Campanas Observatory du Pont Telescope, analyzing a set of about 2700 short exposure spectra of 17

Lithium Metal Anode Fabrication: Methods, Challenges, and Strategies
EcoEnergy, EarlyView.Schematic illustration of four representative fabrication techniques for thin lithium metal anodes: extrusion, molten lithium infusion, electroplating, and physical vapor deposition (PVD). ABSTRACT The pursuit of ultra‐high energy‐dense lithium‐metal batteries (LMBs) has reignited the drive to fabricate ultrathin high‐quality lithium metal anodes. This

Unintentional unfairness when applying new greenhouse gas emissions metrics at country level
Environmental Research Letters, 2019 The 2015 Paris Agreement sets out that rapid reductions in greenhouse gas (GHG) emissions are needed to keep global warming to safe levels. A new approach (known as GWP *) has been suggested to compare contributions of long- and short-lived GHGs ...
